Summary for the public


What is Torisel?

Torisel is a concentrate and diluent that are made up into a solution for infusion (drip into a vein). It contains the active substance temsirolimus.


What is Torisel used for?

Torisel is used to treat patients with the following types of cancer:

  • advanced renal cell carcinoma (a type of kidney cancer). ‘Advanced’ means that the cancer has started to spread;
  • mantle cell lymphoma (an aggressive cancer of a type of white blood cell called B-lymphocytes). Torisel is used in adults when the lymphoma has come back after previous treatment or has not responded to other treatments.

Because the numbers of patients with renal cell carcinoma and mantle cell lymphoma are low, the diseases are considered ‘rare’, and Torisel was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 6 April 2006 (for renal cell carcinoma) and on 6 November 2006 (for mantle cell lymphoma).

The medicine can only be obtained with a prescription.


How is Torisel used?

Torisel must be given under the supervision of a doctor who has experience in the use of anticancer medicines.

For renal cell carcinoma, the recommended dose is 25 mg once a week. For mantle cell lymphoma, it is 175 mg once a week for three weeks, followed by weekly doses of 75 mg.

Torisel is given as an infusion lasting 30 to 60 minutes. Patients should receive an antihistamine to prevent an allergic reaction around 30 minutes before each dose of Torisel. Treatment with Torisel should continue until the patient does not benefit from the medicine any more or has unacceptable side effects. Some side effects can be managed by interrupting treatment or reducing the dose.


How does Torisel work?

The active substance in Torisel, temsirolimus, is an anticancer medicine, which acts by blocking a protein called ‘mammalian target of rapamycin’ (mTOR). In the body, temsirolimus attaches to a protein that is found inside cells to make a ‘complex’. This complex then blocks mTOR. Since mTOR
is involved in the control of cell division, Torisel prevents the division of cancer cells, slowing down the growth and spread of the cancer.


How has Torisel been studied?

In advanced renal cell carcinoma, Torisel has been studied in one main study involving 626 patients who had a poor prognosis. The study compared the effects of 25 mg Torisel given once a week with those of interferon alfa (another anticancer medicine) and with those of 15 mg Torisel once a week in combination with interferon alfa. The main measure of effectiveness was how long the patients survived.

In mantle cell lymphoma, Torisel has been studied in 162 patients whose disease had come back after previous treatment or had not responded to other treatments. Each patient either received one of two doses of Torisel, or the most appropriate alternative treatment chosen by the investigator from a list of medicines commonly used to treat this type of cancer such as gemcitabine and fludarabine. The main measure of effectiveness was how long the patients lived without the disease getting worse.


What benefit has Torisel shown during the studies?

Torisel was more effective than the comparator treatments for both types of cancer.

In advanced renal cell carcinoma, patients receiving Torisel alone survived for an average of 10.9 months, compared with 7.3 months in those receiving interferon alfa alone. The patients receiving the lower dose of Torisel in combination with interferon alfa survived for a similar length of time (8.4 months) as those taking interferon alfa alone.

In mantle cell lymphoma, patients receiving the approved dose of Torisel lived for an average of 4.8 months without their disease getting worse, compared with 1.9 months in those receiving treatment chosen by the investigator.


What is the risk associated with Torisel?

The most common side effects with Torisel (seen in more than 1 patient in 10) are bacterial and viral infections, pneumonia (infection of the lungs), urinary tract infections (infections of the structures that carry urine), pharyngitis (sore throat), upper respiratory tract infection (colds), rhinitis (stuffy and runny nose), thrombocytopenia (low blood platelet counts), anaemia (low red blood cell counts), neutropenia (low levels of neutrophils, a type of white blood cell), leucopenia (low white blood cell counts), lymphopenia (low levels of lymphocytes, a type of white blood cell), hypokalaemia (low blood potassium levels), loss of appetite, hyperglycaemia (high blood sugar levels), diabetes, hypercholesterolaemia (high blood cholesterol levels), hyperlipaemia (high blood fat levels), insomnia (difficulty sleeping), anxiety, dysgeusia (taste disturbances), dyspnoea (difficulty breathing), epistaxis (nose bleeds), cough, abdominal pain (stomach ache), vomiting, stomatitis (inflammation of the lining of the mouth), diarrhoea, nausea (feeling sick), rash, pruritus (itching), acne (spots), nail disorders, dry skin, back pain, arthralgia (joint pain), myalgia (muscle pain), oedema (swelling), asthenia (weakness), pain, pyrexia (fever), mucositis (inflammation of the moist body surfaces), chest pain, chills and increased blood creatinine levels (a marker of kidney problems). For the full list of all side effects reported with Torisel, see the Package Leaflet.

Torisel should not be used in people who may be hypersensitive (allergic) to temsirolimus, to its metabolites (the substances that it is broken down into) including sirolimus (a medicine used to prevent rejection of transplanted kidneys), to polysorbate 80 or to any of the other ingredients of the medicine. Torisel is not recommended for patients with mantle cell lymphoma who have moderate or severe problems with their liver.


Why has Torisel been approved?

The Committee for Medicinal Products for Human Use (CHMP) decided that Torisel’s benefits are greater than its risks for the first-line treatment of patients with advanced renal cell carcinoma who have at least three of six prognostic risk factors, and for the treatment of adult patients with relapsed and/or refractory mantle cell lymphoma. The Committee recommended that Torisel be given marketing authorisation.

4.
CLINICAL PARTICULARS
4.1 Therapeutic indications
Renal cell carcinoma
TORISEL is indicated for the first-line treatment of patients with advanced renal cell carcinoma
(RCC) who have at least three of six prognostic risk factors (see section 5.1).
Mantle cell lymphoma
TORISEL is indicated for the treatment of adult patients with relapsed and/or refractory mantle cell
lymphoma [MCL] (see section 5.1).
4.2 Posology and method of administration
TORISEL must be administered under the supervision of a physician experienced in the use of
antineoplastic medicinal products.
The vial of TORISEL concentrate must first be diluted with 1.8 ml of diluent withdrawn from
the supplied vial to achieve a concentration of temsirolimus of 10 mg/ml. Withdraw the required
amount of the temsirolimus-diluent mixture ( 10 mg/ml) and then inject rapidly into sodium
chloride 9 mg/ml (0.9%) solution for injection.
For instructions on preparation and to help ensure correct dosing, see section 6.6.
Posology
2
Patients should be given intravenous diphenhydramine 25 to 50 mg (or similar antihistamine)
approximately 30 minutes before the start of each dose of temsirolimus.
Treatment with TORISEL should continue until the patient is no longer clinically benefiting from
therapy or until unacceptable toxicity occurs. No special dose modification is required for any of the
populations that have been studied (gender, elderly).
Renal cell carcinoma
The recommended dose of temsirolimus for advanced renal cell carcinoma administered intravenously
is 25 mg infused over a 30- to 60-minute period once weekly (see section 6.6 for instructions on
dilution, administration and disposal).
Management of suspected adverse reactions may require temporary interruption and/or dose reduction
of temsirolimus therapy. If a suspected reaction is not manageable with dose delays, then temsirolimus
may be reduced by 5 mg/week decrements.
Mantle cell lymphoma
The recommended dosing regimen of temsirolimus for mantle cell lymphoma is 175 mg, infused over
a 30-60 minute period once weekly for 3 weeks followed by weekly doses of 75 mg, infused over a
30-60 minute period. The starting dose of 175 mg was associated with a significant incidence of
adverse events and required dose reductions/delays in the majority of patients. The contribution of the
initial 175 mg doses to the efficacy outcome is currently not known.
Management of suspected adverse reactions may require temporary interruption and/or dose reduction
of temsirolimus therapy according to the guidelines in the following tables. If a suspected reaction is
not manageable with dose delays and/or optimal medical therapy, then the dose of temsirolimus should
be reduced according to the dose reduction table below.

a Upon recovery to ANC ≥1.0 x 10 9 /l (1000 cells/mm 3 ) and platelets to ≥50 x 10 9 /l (50,000 cells/mm 3 ), the doses
should be modified to the next lower dose level according to the table above. If the patient cannot maintain
ANC >1.0 x 10 9 /l and platelets >50 x 10 9 /l on the new dose reduction level, then the next lower dose should be
given once the counts have recovered.
Abbreviation: ANC = absolute neutrophil count.
Paediatric population
There is no relevant use of temsirolimus in the paediatric population in the indications treatment of
renal cell carcinoma and treatment of mantle cell lymphoma.
3
 
Temsirolimus should not be used in the paediatric population for the treatment of neuroblastoma,
rhabdomyosarcoma or high-grade glioma, because of efficacy concerns based on the available data
(see section 5.1).
Elderly population
No specific dose adjustment is necessary.
Renal impairment
No dose adjustment of temsirolimus is recommended in patients with renal impairment. Temsirolimus
should be used with caution in patients with severe renal impairment (see section 4.4).
Hepatic impairment
Temsirolimus should be used with caution in patients with hepatic impairment (see section 4.4).
No dose adjustment of temsirolimus is recommended for patients with advanced renal cell carcinoma
(RCC) and mild to moderate hepatic impairment. For patients with RCC and severe hepatic
impairment, the recommended dose for patients who have baseline platelets ≥ 100 x 10 9 /l is 10 mg IV
once a week infused over a 30-60 minute period (see section 5.2).
Method of administration
TORISEL must be administered by intravenous (IV) infusion. For instructions on dilution and
preparation of the medicinal product before administration, see section 6.6.
4.3 Contraindications
Hypersensitivity to temsirolimus, its metabolites (including sirolimus), polysorbate 80, or to any of the
excipients of TORISEL.
Use of temsirolimus in patients with mantle cell lymphoma with moderate or severe hepatic
impairment is not recommended (see section 4.4).
4.4 Special warnings and precautions for use
The incidence and severity of adverse events is dose-dependent. Patients receiving the starting dose of
175 mg weekly for the treatment of MCL must be followed closely to decide on dose
reductions/delays.
Paediatric population
Temsirolimus is not recommended for use in paediatric patients (see sections 4.2, 4.8 and 5.1).
Elderly population
Based on the results of a phase 3 study in renal cell carcinoma, elderly patients (≥ 65 years of age) may
be more likely to experience certain adverse reactions, including oedema, diarrhoea, and pneumonia.
Based on the results of a phase 3 study in mantle cell lymphoma, elderly patients (≥ 65 years of age)
may be more likely to experience certain adverse reactions, including pleural effusion, anxiety,
depression, insomnia, dyspnoea, leukopaenia, lymphopaenia, myalgia, arthralgia, taste loss, dizziness,
upper respiratory infection, mucositis, and rhinitis.
4
Renal impairment
Temsirolimus elimination by the kidneys is negligible; studies in patients with varying renal
impairment have not been conducted (see sections 4.2 and 5.2). TORISEL has not been studied in
patients undergoing haemodialysis.
Renal failure
Renal failure (including fatal outcomes) has been observed in patients receiving TORISEL for
advanced renal cell cancer and/or with pre-existing renal insufficiency (see section 4.8).
Hepatic impairment
Temsirolimus is cleared predominantly by the liver. Based on an open-label, dose-escalation study in
112 subjects with advanced malignancies and either normal or impaired hepatic function, no dose
adjustment of temsirolimus is recommended for patients with baseline platelet counts ≥ 100x10 9 /l and
advanced renal cell carcinoma (RCC) and mild to moderate hepatic impairment (total bilirubin up to 3
times upper limit of normal [ULN] with any abnormality of AST, or as defined by Child-Pugh Class A
or B). For patients with RCC and severe hepatic impairment (total bilirubin > 3 times ULN with any
abnormality of AST, or as defined by Child-Pugh Class C), the recommended dose for patients who
have baseline platelets ≥ 100 x 10 9 /l is 10 mg IV once a week infused over a 30-60 minute period (see
section 4.2).
Intracerebral bleeding
Patients with central nervous system (CNS) tumours (primary CNS tumours or metastases) and/or
receiving anticoagulation therapy may be at an increased risk of developing intracerebral bleeding
(including fatal outcomes) while receiving therapy with temsirolimus.
Thrombocytopaenia and neutropaenia
Grades 3 and 4 thrombocytopaenia and/or neutropaenia have been observed in the MCL Clinical Trial
(see section 4.8). Patients on temsirolimus who develop thrombocytopaenia may be at increased risk of
bleeding events, including epistaxis (see section 4.8). Patients on temsirolimus with baseline
neutropaenia may be at risk of developing febrile neutropaenia.
Infections
Patients may be immunosuppressed and should be carefully observed for the occurrence of infections,
including opportunistic infections. Among patients receiving 175 mg/week for the treatment of MCL,
infections (including grade 3 and 4 infections) were substantially increased compared to lower doses
and compared to conventional chemotherapy.
Cataracts
Cataracts have been observed in some patients who received the combination of temsirolimus and
interferon-α.
Hypersensitivity/infusion reactions
Hypersensitivity/infusion reactions (including some life-threatening and rare fatal reactions), including
and not limited to flushing, chest pain, dyspnoea, hypotension, apnoea, loss of consciousness,
hypersensitivity and anaphylaxis, have been associated with the administration of temsirolimus (see
section 4.8). These reactions can occur very early in the first infusion, but may also occur with
subsequent infusions. Patients should be monitored early during the infusion and appropriate
supportive care should be available. Temsirolimus infusion should be interrupted in all patients with
severe infusion reactions and appropriate medical therapy administered. A benefit-risk assessment
5
should be done prior to the continuation of temsirolimus therapy in patients with severe or life-
threatening reactions.
If a patient develops a hypersensitivity reaction during the TORISEL infusion, despite the
premedication, the infusion must be stopped and the patient observed for at least 30 to 60 minutes
(depending on the severity of the reaction). At the discretion of the physician, treatment may be
resumed after the administration of an H 1 -receptor antagonist (diphenhydramine or similar
antihistamine) and a H 2 -receptor antagonist (intravenous famotidine 20 mg or intravenous ranitidine
50 mg) approximately 30 minutes before restarting the TORISEL infusion. Administration of
corticosteroids may be considered; however, the efficacy of corticosteroid treatment in this setting has
not been established. The infusion may then be resumed at a slower rate (up to 60 minutes) and should
be completed within six hours from the time that TORISEL is first added to sodium chloride 9 mg/ml
(0.9%) solution for injection.
Because it is recommended that an H 1 antihistamine be administered to patients before the start of the
intravenous temsirolimus infusion, temsirolimus should be used with caution in patients with known
hypersensitivity to the antihistamine or in patients who cannot receive the antihistamine for other
medical reasons.
Hypersensitivity reactions, including anaphylactic/anaphylactoid reactions, angioedema, exfoliative
dermatitis and hypersensitivity vasculitis, have been associated with the oral administration of
sirolimus.
Hyperglycaemia/glucose intolerance/diabetes mellitus
Patients should be advised that treatment with TORISEL may be associated with an increase in blood
glucose levels in diabetic and non-diabetic patients. In the RCC Clinical Trial, a phase 3 clinical trial
for renal cell carcinoma, 26% of patients reported hyperglycaemia as an adverse event. In the MCL
Clinical Trial, a phase 3 clinical trial for mantle cell lymphoma, 11% of patients reported
hyperglycaemia as an adverse event. This may result in the need for an increase in the dose of, or
initiation of, insulin and/or hypoglycaemic agent therapy. Patients should be advised to report
excessive thirst or any increase in the volume or frequency of urination.
Interstitial lung disease
There have been cases of non-specific interstitial pneumonitis, including fatal reports, occurring in
patients who received weekly intravenous TORISEL. Some patients were asymptomatic or had
minimal symptoms with pneumonitis detected on computed tomography scan or chest radiograph.
Others presented with symptoms such as dyspnoea, cough, and fever. Some patients required
discontinuation of TORISEL or treatment with corticosteroids and/or antibiotics, while some patients
continued treatment without additional intervention. It is recommended that patients undergo baseline
radiographic assessment by lung computed tomography scan or chest radiograph prior to the initiation
of TORISEL therapy. Periodical follow-up assessments may be considered. It is recommended that
patients be followed closely for occurrence of clinical respiratory symptoms and patients should be
advised to report promptly any new or worsening respiratory symptoms. If clinically significant
respiratory symptoms develop, consider withholding TORISEL administration until after recovery of
symptoms and improvement of radiographic findings related to pneumonitis. Empiric treatment with
corticosteroids and/or antibiotics may be considered.
Hyperlipaemia
The use of TORISEL was associated with increases in serum triglycerides and cholesterol. In the RCC
Clinical Trial 1, hyperlipaemia was reported as an adverse event in 27% of patients. In the MCL
Clinical Trial, hyperlipaemia was reported as an adverse event in 9.3% of patients. This may require
initiation, or increase, in the dose of lipid-lowering agents. Serum cholesterol and triglycerides should
be tested before and during treatment with TORISEL.
6
Wound healing complications
The use of TORISEL has been associated with abnormal wound healing; therefore, caution should be
exercised with the use of TORISEL in the peri-surgical period.
Concomitant use of temsirolimus with sunitinib
The combination of temsirolimus and sunitinib resulted in dose-limiting toxicity. Dose-limiting
toxicities (grade 3/4 erythematous maculopapular rash, gout/cellulitis requiring hospitalisation) were
observed in two out of three patients treated in the first cohort of a phase 1 study at doses of
temsirolimus 15 mg intravenous per week and sunitinib 25 mg oral per day (days 1-28 followed by a
2-week rest).
Concomitant use of angiotensin-converting enzyme (ACE) inhibitors
Angioneurotic oedema-type reactions (including delayed reactions occurring two months following
initiation of therapy) have been observed in some patients who received temsirolimus and ACE
inhibitors concomitantly (see section 4.5).
Agents inducing CYP3A metabolism
Agents such as carbamazepine, phenobarbital, phenytoin, rifampicin, and St. John’s Wort are strong
inducers of CYP3A4/5 and may decrease composite exposure of the active moieties, temsirolimus and
its metabolite, sirolimus. Therefore, for patients with renal cell carcinoma, continuous administration
beyond 5-7 days with agents that have CYP3A4/5 induction potential should be avoided. For patients
with mantle cell lymphoma, it is recommended that coadministration of CYP3A4/5 inducers should be
avoided due to the higher dose of temsirolimus (see section 4.5).
Agents inhibiting CYP3A metabolism
Agents such as protease inhibitors (nelfinavir, ritonavir), antifungals (e.g., itraconazole, ketoconazole,
voriconazole), and nefazodone are strong CYP3A4 inhibitors and may increase blood concentrations
of the active moieties, temsirolimus and its metabolite, sirolimus. Therefore, concomitant treatment
with agents that have strong CYP3A4 inhibition potential should be avoided. Concomitant treatment
with moderate CYP3A4 inhibitors (e.g., aprepitant, erythromycin, fluconazole, verapamil, grapefruit
juice) should only be administered with caution in patients receiving 25 mg and should be avoided in
patients receiving temsirolimus doses higher than 25 mg (see section 4.5). Alternative treatments with
agents that do not have CYP3A4 inhibition potential should be considered (see section 4.5).
Vaccinations
Immunosuppressants may affect responses to vaccination. During treatment with TORISEL,
vaccination may be less effective. The use of live vaccines should be avoided during treatment with
TORISEL. Examples of live vaccines are: measles, mumps, rubella, oral polio, BCG, yellow fever,
varicella, and TY21a typhoid vaccines.
Excipients
After first dilution of TORISEL 30 mg concentrate with 1.8 ml of withdrawn diluent, the concentrate-
diluent mixture contains 35% volume ethanol (alcohol); i.e., up to 0.693 g per 25 mg dose of
TORISEL, equivalent to 17.6 ml beer, 7.3 ml wine per dose. Patients administered the higher dose of
175 mg of TORISEL for the initial treatment of MCL may receive up to 4.85 g of ethanol (equivalent
to 123 ml beer, 51 ml wine per dose).
Harmful for those suffering from alcoholism.
7
To be taken into account in pregnant or breast-feeding women, children and high-risk groups, such as
patients with liver disease or epilepsy. The amount of alcohol in this medicinal product may alter the
effects of other medicines. The amount of alcohol in this medicinal product may impair your ability to
drive or use machines.
4.5 Interaction with other medicinal products and other forms of interaction
Interaction studies have only been performed in adults.
Concomitant use of angiotensin-converting enzyme (ACE) inhibitors
Angioneurotic oedema-type reactions (including delayed reactions occurring two months following
initiation of therapy) have been observed in some patients who received temsirolimus and ACE
inhibitors concomitantly (see section 4.4).
Agents inducing CYP3A metabolism
Co-administration of TORISEL with rifampicin, a potent CYP3A4/5 inducer, had no significant effect
on temsirolimus C max (maximum concentration) and AUC (area under the concentration vs. time
curve) after intravenous administration, but decreased sirolimus C max by 65% and AUC by 56%,
compared to TORISEL treatment alone. Therefore, concomitant treatment with agents that have
CYP3A4/5 induction potential should be avoided [e.g., carbamazepine, phenobarbital, phenytoin,
rifampicin, and St. John’s Wort] (see section 4.4).
Agents inhibiting CYP3A metabolism
Co-administration of TORISEL 5 mg with ketoconazole, a potent CYP3A4 inhibitor, had no
significant effect on temsirolimus C max or AUC; however, sirolimus AUC increased 3.1-fold, and
AUC sum (temsirolimus + sirolimus) increased 2.3-fold compared to TORISEL alone. The effect on the
unbound concentrations of sirolimus has not been determined, but is expected to be larger than the
effect on whole-blood concentrations due to the saturable binding to red blood cells. The effect may
also be more pronounced at a 25 mg dose. Therefore, substances that are potent inhibitors of CYP3A4
activity (e.g., nelfinavir, ritonavir, itraconazole, ketoconazole, voriconazole, nefazodone) increase
sirolimus blood concentrations. Concomitant treatment of TORISEL with these agents should be
avoided see section 4.4).
Concomitant treatment with moderate CYP3A4 inhibitors (e.g., diltiazem, verapamil, clarithromycin,
erythromycin, aprepitant, amiodarone) should only be administered with caution in patients receiving
25 mg and should be avoided in patients receiving temsirolimus doses higher than 25 mg.
Interaction with medicinal products metabolised by CYP2D6 or CYP3A4
In 23 healthy subjects, the concentration of desipramine, a CYP2D6 substrate, was unaffected when
25 mg of temsirolimus was co-administered. No clinically significant effect is anticipated when
TORISEL is co-administered with agents that are metabolised by CYP2D6 in patients with renal cell
carcinoma. For patients with mantle cell lymphoma, the effect of a 175 or 75 mg temsirolimus dose on
CYP2D6 or 3A4 substrates has not been studied. However, based on in vitro studies in human liver
microsomes, the plasma concentrations achieved after a 175 mg dose of temsirolimus might possibly
lead to inhibition of CYP3A4/5 and CYP2D6 (see section 5.2). Therefore, caution is advised during
concomitant administration of temsirolimus at a dose of 175 mg with medicinal products that are
metabolised via CYP3A4/5 or CYP2D6 and that have a narrow therapeutic index.
Interactions with drugs that are P-glycoprotein substrates
In an in vitro study, temsirolimus inhibited the transport of P-glycoprotein (P-gp) substrates with an
IC 50 value of 2 µM. In vivo , the effect of P-gp inhibition has not been investigated, but mean C max
concentrations of temsirolimus are 2.6 µM in MCL patients receiving the 175 mg IV dose of
8
temsirolimus. Therefore, when temsirolimus is co-administered with medications which are P-gp
substrates (e.g. digoxin, vincristine, colchicine, and paclitaxel) close monitoring for adverse events
related to the co-administered drugs should be observed.
Amphiphilic agents
Temsirolimus has been associated with phospholipidosis in rats. Phospholipidosis has not been
observed in mice or monkeys treated with temsirolimus, nor has it been documented in patients treated
with temsirolimus. Although phospholipidosis has not been shown to be a risk for patients
administered temsirolimus, it is possible that combined administration of temsirolimus with other
amphiphilic agents such as amiodarone or statins could result in an increased risk of amphiphilic
pulmonary toxicity.
4.6 Fertility, pregnancy and lactation
Women of childbearing potential/ Contraception in males and females
Due to the unknown risk related to potential exposure during early pregnancy, women of childbearing
potential must be advised not to become pregnant while using TORISEL.
Men with partners of childbearing potential should use medically acceptable contraception while
receiving TORISEL (see section 5.3).
Pregnancy
There are no adequate data from the use of temsirolimus in pregnant women. Studies in animals have
shown reproductive toxicity. In reproduction studies in animals, temsirolimus caused
embryo/foetotoxicity that was manifested as mortality and reduced foetal weights (with associated
delays in skeletal ossification) in rats and rabbits. Teratogenic effects (omphalocele) were seen in
rabbits (see section 5.3).
The potential risk for humans is unknown. TORISEL must not be used during pregnancy, unless the
risk for the embryo is justified by the expected benefit for the mother.
Breastfeeding
It is unknown whether temsirolimus is excreted in human breast milk. The excretion of temsirolimus
in milk has not been studied in animals. However, sirolimus, the main metabolite of temsirolimus, is
excreted in milk of lactating rats. Because of the potential for adverse reactions in breast-fed infants
from temsirolimus, breast-feeding should be discontinued during therapy.
Fertility
In male rats, decreased fertility and partly reversible reductions in sperm counts were reported (see
section 5.3).
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed.
For patients receiving the higher dose of 175 mg IV of TORISEL for the treatment of MCL, the
amount of ethanol in this medicinal product may impair your ability to drive or use machines (see
section 4.4).
9
4.8 Undesirable effects
Due to the different approved posology for RCC and MCL and the dose-dependency of the frequency
and severity of undesirable effects, adverse drug reactions are listed separately.
Renal cell carcinoma
A total of 626 patients were randomly assigned in a phase 3, three-arm, randomised, open-label study
of Interferon alfa (IFN-α) alone, TORISEL alone, and TORISEL and IFN-α. A total of 616 patients
received treatment: 200 patients received IFN-α weekly; 208 received TORISEL 25 mg weekly, and
208 patients received a combination of IFN-α and TORISEL weekly. Based on the results of the
phase 3 study, elderly patients may be more likely to experience certain adverse reactions, including
face oedema and pneumonia.
The most serious reactions observed with TORISEL are hypersensitivity/infusion reactions (including
some life-threatening and rare fatal reactions), hyperglycaemia/glucose intolerance, infections,
interstitial lung disease (pneumonitis), hyperlipaemia, intracerebral bleeding, renal failure, bowel
perforation, and wound healing complication.
The most common (≥30%) adverse reactions (all grades) observed with TORISEL include anaemia,
nausea, rash (including rash, pruritic rash, maculopapular rash, pustular rash), anorexia, oedema
(including facial oedema and peripheral oedema), and asthenia.
Cataracts have been observed in some patients who received the combination of temsirolimus and
interferon-α.
See section 4.4 for additional information concerning serious adverse reactions, including appropriate
actions to be taken if specific reactions occur.

Mantle cell lymphoma
A total of 54 patients were treated with 175/75 mg TORISEL in the MCL Clinical Trial, a phase 3,
three-arm, randomised, open-label study of TORISEL comparing 2 different dosing regimens of
temsirolimus with an investigator's choice of therapy in patients with relapsed and/or refractory mantle
cell lymphoma. Based on the results of the phase 3 study, elderly patients (≥65 years) may be more
likely to experience certain adverse reactions, including pleural effusion, anxiety, depression,
insomnia, dyspnoea, leukopaenia, lymphopaenia, myalgia, arthralgia, taste loss, dizziness, upper
respiratory infection, mucositis, and rhinitis.
The most serious reactions observed with TORISEL are thrombocytopaenia, neutropaenia, infections,
interstitial lung disease (pneumonitis), bowel perforation, hypersensitivity reactions, and
hyperglycaemia/glucose intolerance.
The most common (≥30%) adverse reactions (all grades) observed with TORISEL include
thrombocytopaenia, asthenia, anaemia, diarrhoea, bacterial and viral infections*, rash*, pyrexia,
anorexia, epistaxis, mucositis, oedema*, and stomatitis*.
The occurrence of undesirable effects following the dose of 175 mg TORISEL/week for MCL, e.g.
grade 3 or 4 infections or thrombocytopaenia, is associated with a higher incidence than that observed
with either 75 mg TORISEL/week or conventional chemotherapy.

*Body system totals are not necessarily the sum of the individual adverse events since a subject may report two
or more different adverse events in the same body system.
**Grades 3 and 4 (thrombocytopaenia) are defined as 50,000-25,000 platelets/mm 3 and <25,000 platelets/mm 3 ,
respectively. Grades 3 and 4 (neutropaenia) are defined as 1000-500 neutrophils/mm 3 and <500 neutrophils/mm 3 ,
respectively.
***Patients should be advised that treatment with TORISEL may be associated with an increase in blood glucose
levels in diabetic and non-diabetic patients.
****One case of fatal pneumonitis was reported in a mantle cell lymphoma patient receiving 175/25 mg/week
that is not included in this table.
Serious adverse reactions observed in clinical trials of temsirolimus for advanced renal cell carcinoma,
but not in clinical trials of temsirolimus for mantle cell lymphoma include: anaphylaxis, impaired
wound healing, renal failure with fatal outcomes, and pulmonary embolus.
Adverse reactions for which frequency is undetermined
Angioneurotic oedema-type reactions in some patients who received temsirolimus and ACE-inhibitors
concomitantly.
Post Marketing Experience
There have been reports of Stevens-Johnson syndrome in patients who received TORISEL.
There have been reports of rhabdomyolysis in patients who received TORISEL.
Paediatric population
In a phase 1/2 study, 71 patients (59 patients, aged from 1 to 17 years old, and 12 patients, aged 18 to
21 years) were administered temsirolimus at doses ranging from 10 mg/m 2 to 150 mg/m 2 (see section
5.1).
The adverse reactions reported by the highest percentage of patients were haematologic (anaemia,
leukopaenia, neutropaenia, and thrombocytopaenia), metabolic (hypercholesterolaemia, hyperlipaemia,
hyperglycaemia, increase of serum aspartate amino transferase [AST] and serum alanine
aminotransferase [ALT] plasma levels), and digestive (mucositis, stomatitis, nausea, and vomiting).
4.9 Overdose
There is no specific treatment for TORISEL intravenous overdose. While TORISEL has been safely
administered to patients with renal cancer with repeated intravenous doses of temsirolimus as high as
220 mg/m 2 , in MCL, two administrations of 330 mg TORISEL/week in one patient resulted in grade 3
rectal bleeding and grade 2 diarrhoea.

PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Protein Kinase Inhibitors; ATC code: L01X E09
Temsirolimus is a selective inhibitor of mTOR (mammalian target of rapamycin). Temsirolimus binds
to an intracellular protein (FKBP-12), and the protein/temsirolimus complex binds and inhibits the
activity of mTOR that controls cell division. In vitro , at high concentrations (10-20 µM), temsirolimus
can bind and inhibit mTOR in the absence of FKBP-12. Biphasic dose response of cell growth
inhibition was observed. High concentrations resulted in complete cell growth inhibition in vitro ,
whereas inhibition mediated by FKBP-12/temsirolimus complex alone resulted in approximately 50%
decrease in cell proliferation. Inhibition of mTOR activity results in a G1 growth delay at nanomolar
concentrations and growth arrest at micromolar concentrations in treated tumour cells resulting from
15
selective disruption of translation of cell cycle regulatory proteins, such as D-type cyclins, c-myc, and
ornithine decarboxylase. When mTOR activity is inhibited, its ability to phosphorylate, and thereby
control the activity of protein translation factors (4E-BP1 and S6K, both downstream of mTOR in the
P13 kinase/AKT pathway) that control cell division, is blocked.
In addition to regulating cell cycle proteins, mTOR can regulate translation of the hypoxia-inducible
factors, HIF-1 and HIF-2 alpha. These transcription factors regulate the ability of tumours to adapt to
hypoxic microenvironments and to produce the angiogenic factor vascular endothelial growth factor
(VEGF). The anti-tumour effect of temsirolimus, therefore, may also in part stem from its ability to
depress levels of HIF and VEGF in the tumour or tumour microenvironment, thereby impairing vessel
development.
Clinical Efficacy
Renal cell carcinoma
The safety and efficacy of TORISEL in the treatment of advanced renal cell carcinoma were studied in
the following two randomised clinical trials:
RCC Clinical Trial 1
RCC Clinical Trial 1 was a phase 3, multi-centre, three-arm, randomised, open-label study in
previously untreated patients with advanced renal cell carcinoma and with 3 or more of 6 pre-selected
prognostic risk factors (less than one year from time of initial renal cell carcinoma diagnosis to
randomisation, Karnofsky performance status of 60 or 70, haemoglobin less than the lower limit of
normal, corrected calcium of greater than 10 mg/dl, lactate dehydrogenase>1.5 times the upper limit of
normal, more than one metastatic organ site). The primary study endpoint was overall survival (OS).
Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), clinical
benefit rate, time to treatment failure (TTF), and quality adjusted survival measurement. Patients were
stratified for prior nephrectomy status within three geographic regions and were randomly assigned
(1:1:1) to receive IFN-α alone (n = 207), TORISEL alone (25 mg weekly; n = 209), or the combination
of IFN-α and TORISEL (n = 210).
In RCC Clinical Trial 1, TORISEL 25 mg was associated with a statistically significant advantage
over IFN-α in the primary endpoint of OS at the 2 nd pre-specified interim analysis (n = 446 events,
p = 0.0078). The TORISEL arm showed a 49% increase in median OS compared with the IFN-α arm.
TORISEL also was associated with statistically significant advantages over IFN-α in the secondary
endpoints of PFS, TTF, and clinical benefit rate.
The combination of TORISEL 15 mg and IFN-α did not result in a significant increase in overall
survival when compared with IFN-α alone at either the interim analysis (median 8.4 vs. 7.3 months,
hazard ratio = 0.96, p = 0.6965) or final analysis (median 8.4 vs. 7.3 months, hazard ratio = 0.93,
p = 0.4902). Treatment with the combination of TORISEL and IFN-α resulted in a statistically
significant increase in the incidence of certain grade 3-4 adverse events (weight loss, anaemia,
neutropaenia, thrombocytopaenia and mucosal inflammation) when compared with the adverse events
observed in the IFN-α or TORISEL-alone arms.

In RCC Clinical Trial 1, 31% of patients treated with TORISEL were 65 or older. In patients younger
than 65, median overall survival was 12 months (95% CI 9.9, 14.2) with a hazard ratio of 0.67
(95% CI 0.52, 0.87) compared with those treated with IFN-α. In patients 65 or older, median overall
survival was 8.6 months (95% CI 6.4, 11.5) with a hazard ratio of 1.15 (95% CI 0.78, 1.68) compared
with those treated with IFN-α.
RCC Clinical Trial 2
RCC Clinical Trial 2 was a randomised, double-blind, multi-centre, outpatient trial to evaluate the
efficacy, safety, and pharmacokinetics of three dose levels of TORISEL when administered to
previously treated patients with advanced renal cell carcinoma. The primary efficacy endpoint was
ORR, and OS was also evaluated. One hundred eleven (111) patients were randomly assigned in a
1:1:1 ratio to receive 25 mg, 75 mg, or 250 mg temsirolimus intravenous weekly. In the 25 mg arm
(n = 36), all patients had metastatic disease; 4 (11%) had no prior chemo- or immunotherapy; 17
(47%) had one prior treatment, and 15 (42%) had 2 or more prior treatments for renal cell carcinoma.
Twenty-seven (27, 75%) had undergone a nephrectomy. Twenty-four (24, 67%) were Eastern
Cooperative Oncology Group (ECOG) performance status (PS) = 1, and 12 (33%) were ECOG PS = 0.
For patients treated weekly with 25 mg temsirolimus OS was 13.8 months (95% CI: 9.0, 18.7 months);
ORR was 5.6% (95% CI: 0.7, 18.7%).
Mantle cell lymphoma
The safety and efficacy of intravenous (IV) temsirolimus for the treatment of relapsed and/or
refractory mantle cell lymphoma were studied in the following phase 3 clinical study.

MCL Clinical Trial
MCL Clinical Trial is a controlled, randomised, open-label, multicenter, outpatient study comparing 2
different dosing regimens of temsirolimus with an investigator's choice of therapy in patients with
relapsed and/or refractory mantle cell lymphoma. Subjects with mantle cell lymphoma (that was
confirmed by histology, immunophenotype, and cyclin D1 analysis) who had received 2 to 7 prior
therapies that included anthracyclines and alkylating agents, and rituximab (and could include
haematopoietic stem cell transplant) and whose disease was relapsed and/or refractory were eligible
for the study. Subjects were randomly assigned in a 1:1:1 ratio to receive temsirolimus IV 175 mg
(3 successive weekly doses) followed by 75 mg weekly (n = 54), temsirolimus IV 175 mg
(3 successive weekly doses) followed by 25 mg weekly (n=54), or the investigator’s choice of
single-agent treatment (as specified in the protocol; n = 54). Investigator's choice therapies included:
gemcitabine (IV: 22 [41.5%]), fludarabine (IV: 12 [22.6%] or oral: 2 [3.8%]), chlorambucil (oral:
3 [5.7%]), cladribine (IV: 3 [5.7%]), etoposide (IV: 3 [5.7%]), cyclophosphamide (oral: 2 [3.8%]),
thalidomide (oral: 2 [3.8%]), vinblastine (IV: 2 [3.8%]), alemtuzumab (IV: 1 [1.9%]), and
lenalidomide (oral: 1 [1.9%]). The primary endpoint of the study was progression-free survival (PFS),
as assessed by an independent radiologist and oncology review. Secondary efficacy endpoints included
overall survival (OS) and objective response rate (ORR).
The results for the MCL Clinical Trial are summarized in the following table. Temsirolimus 175/75
(temsirolimus 175 mg weekly for 3 weeks followed by 75 mg weekly) led to an improvement in PFS
compared with investigator's choice in patients with relapsed and/or refractory mantle cell lymphoma
that was statistically significant (hazard ratio = 0.44; p-value = 0.0009). Median PFS of the
temsirolimus 175/75 mg group (4.8 months) was prolonged by 2.9 months compared to the
investigator's choice group (1.9 months). Overall survival was similar.
Temsirolimus also was associated with statistically significant advantages over investigator’s choice in
the secondary endpoint of overall response rate (ORR). The evaluations of PFS and ORR were based
on blinded independent radiologic assessment of tumour response using the International Workshop
Criteria.

The temsirolimus 175 mg (3 successive weekly doses) followed by 25 mg weekly treatment arm did
not result in a significant increase in PFS when compared with investigator’s choice (median
3.4 vs. 1.9 months, hazard ratio = 0.65, CI = 0.39, 1.10, p = 0.0618).
In the MCL Clinical Trial, there was no difference in efficacy in patients with respect to age, sex, race,
geographic region, or baseline disease characteristics.
Paediatric population
In a phase 1/2 safety and exploratory efficacy study, 71 patients (59 patients, aged from 1 to 17 years,
and 12 patients, aged from 18 to 21 years) received temsirolimus as a 60-minute IV infusion once
weekly in three-week cycles. In part 1, 14 patients aged from 1 to 17 years with advanced
recurrent/refractory solid tumours received temsirolimus at doses ranging from 10 mg/m 2 to
150 mg/m 2 . In part 2, 45 patients aged from 1 to 17 years with recurrent/relapsed rhabdomyosarcoma,
neuroblastoma, or high grade glioma were administered temsirolimus at a weekly dose of 75 mg/m 2 .
Adverse events were generally similar to those observed in adults (see section 4.8).
Temsirolimus was found to be ineffective in paediatric patients with neuroblastoma,
rhabdomyosarcoma, and high-grade glioma (n = 52). For subjects with neuroblastoma, the objective
response rate was 5.3% (95% CI: 0.1%, 26.0%). After 12 weeks of treatment, no response was
observed in subjects with rhabdomyosarcoma or high-grade glioma. None of the 3 cohorts met the
criterion for advancing to the second stage of the Simon 2-stage design.
5.2 Pharmacokinetic properties
Absorption
Following administration of a single 25 mg intravenous dose of temsirolimus in patients with cancer,
mean C max in whole blood was 585 ng/ml (coefficient of variation, CV = 14%), and mean AUC in
blood was 1627 ng•h/ml (CV = 26%). For patients receiving 175 mg weekly for 3 weeks followed by
75 mg weekly, estimated C max in whole blood at end of infusion was 2457 ng/ml during week 1, and
2574 ng/ml during week 3.
Distribution
Temsirolimus exhibits a polyexponential decline in whole blood concentrations, and distribution is
attributable to preferential binding to FKBP-12 in blood cells. The mean (standard deviation, SD)
dissociation constant (K d ) of binding was 5.1 (3.0) ng/ml, denoting the concentration at which 50% of
binding sites in blood cells were occupied. Temsirolimus distribution is dose-dependent with mean
(10th, 90th percentiles) maximal specific binding in blood cells of 1.4 mg (0.47 to 2.5 mg). Following
a single 25 mg temsirolimus intravenous dose, mean steady-state volume of distribution in whole
blood of patients with cancer was 172 liters.
Metabolism
Sirolimus, an equally potent metabolite to temsirolimus, was observed as the principal metabolite in
humans following intravenous treatment. During in vitro temsirolimus metabolism studies, sirolimus,
seco-temsirolimus and seco-sirolimus were observed; additional metabolic pathways were
hydroxylation, reduction and demethylation. Following a single 25 mg intravenous dose in patients
with cancer, sirolimus AUC was 2.7-fold that of temsirolimus AUC, due principally to the longer
half-life of sirolimus.
Elimination
Following a single 25 mg intravenous dose of temsirolimus, temsirolimus mean ± SD systemic
clearance from whole blood was 11.4 ± 2.4 l/h. Mean half-lives of temsirolimus and sirolimus were
19
17.7 hr and 73.3 hr, respectively. Following administration of [ 14 C] temsirolimus, excretion was
predominantly via the faeces (78%), with renal elimination of active substance and metabolites
accounting for 4.6% of the administered dose. Sulfate or glucuronide conjugates were not detected in
the human faecal samples, suggesting that sulfation and glucuronidation do not appear to be major
pathways involved in the excretion of temsirolimus. Therefore, inhibitors of these metabolic pathways
are not expected to affect the elimination of temsirolimus.
Model-predicted values for clearance from plasma, after applying a 175 mg dose for 3 weeks, and
subsequently 75 mg for 3 weeks, indicate temsirolimus and sirolimus metabolite trough concentrations
of approximately 1.2 ng/ml and 10.7 ng/ml, respectively.
Temsirolimus and sirolimus were demonstrated to be substrates for P-gp in vitro . Possible effects of
inhibition of P-gp on elimination of temsirolimus and sirolimus in vivo have not been investigated.
Inhibition of CYP isoforms
In in vitro studies in human liver microsomes, temsirolimus inhibited CYP3A4/5, CYP2D6, CYP2C9
and CYP2C8 catalytic activity with Ki values of 3.1, 1.5, 14 and 27 µM, respectively. IC 50 values for
inhibition of CYP2B6 and CYP2E1 by temsirolimus were 48 and 100 µM, respectively. Based on a
whole blood mean C max concentration of 2.6 µM for temsirolimus in MCL patients receiving the
175 mg dose there is a potential for interactions with concomitantly administered drugs that are
substrates of CYP3A4/5 and CYP2D6 in patients treated with the 175 mg dose of temsirolimus (see
section 4.5). However, it is unlikely that whole blood concentrations of temsirolimus after IV
administration of temsirolimus will inhibit the metabolic clearance of concomitant drugs that are
substrates of CYP2C9, CYP2C8, CYP2B6 or CYP2E1.
Special Populations
Hepatic impairment
Temsirolimus and sirolimus pharmacokinetics have been investigated in an open-label, dose-escalation
study in 112 patients with advanced malignancies and either normal or impaired hepatic function. For
7 patients with severe hepatic impairment (ODWG, group D) receiving the 10 mg dose of
temsirolimus, the mean AUC of temsirolimus was ~1.7-fold higher compared to 7 patients with mild
hepatic impairment (ODWG, group B). For patients with severe hepatic impairment, a reduction of the
temsirolimus dose to 10 mg is recommended to provide levels of temsirolimus and sirolimus
exposures in blood (AUC sum 6580 ng·h/ml), which approximate to those following the 25 mg dose
(AUC sum 7280 ng·h/ml) in patients with normal liver function (see sections 4.2 and 4.4).
Gender, weight, race, age
Temsirolimus and sirolimus pharmacokinetics are not significantly affected by gender. No relevant
differences in exposure were apparent when data from the Caucasian population was compared with
either the Japanese or Black population.
In population pharmacokinetic-based data analysis, increased body weight (between 38.6 and
158.9 kg) was associated with a two-fold range of trough concentration of sirolimus in whole blood.
Pharmacokinetic data on temsirolimus and sirolimus are available in patients up to age 79 years. Age
does not appear to affect temsirolimus and sirolimus pharmacokinetics significantly.
Paediatric population
In the paediatric population, clearance of temsirolimus was lower and exposure (AUC) was higher
than in adults. In contrast, exposure to sirolimus was commensurately reduced in paediatric patients,
such that the net exposure as measured by the sum of temsirolimus and sirolimus AUCs (AUC sum ) was
comparable to that for adults.
20
5.3 Preclinical safety data
Adverse reactions not observed in clinical studies, but seen in animals at exposure levels similar to or
even lower than clinical exposure levels and with possible relevance to clinical use, were as follows:
pancreatic islet cell vacuolation (rat), testicular tubular degeneration (mouse, rat and monkey),
lymphoid atrophy (mouse, rat and monkey), mixed cell inflammation of the colon/caecum (monkey),
and pulmonary phospholipidosis (rat).
Diarrhoea with mixed cell inflammation of the caecum or colon was observed in monkeys and was
associated with an inflammatory response, and may have been due to a disruption of the normal
intestinal flora.
General inflammatory responses, as indicated by increased fibrinogen and neutrophils, and/or changes
in serum protein, were observed in mice, rats, and monkeys, although in some cases these clinical
pathology changes were attributed to skin or intestinal inflammation as noted above. For some
animals, there were no specific clinical observations or histological changes that suggested
inflammation.
Temsirolimus was not genotoxic in a battery of in vitro (bacterial reverse mutation in Salmonella
typhimurium and Escherichia coli , forward mutation in mouse lymphoma cells, and chromosome
aberrations in Chinese hamster ovary cells) and in vivo (mouse micronucleus) assays.
Carcinogenicity studies have not been conducted with temsirolimus; however, sirolimus, the major
metabolite of temsirolimus in humans, was carcinogenic in mice and rats. The following effects were
reported in mice and/or rats in the carcinogenicity studies conducted: granulocytic leukaemia,
lymphoma, hepatocellular adenoma and carcinoma, and testicular adenoma.
Reductions in testicular weights and/or histological lesions (e.g., tubular atrophy and tubular giant
cells) were observed in mice, rats, and monkeys. In rats, these changes were accompanied by a
decreased weight of accessory sex organs (epididymides, prostate, seminal vesicles). In reproduction
toxicity studies in animals, decreased fertility and partly reversible reductions in sperm counts were
reported in male rats. Exposures in animals were lower than those seen in humans receiving clinically
relevant doses of temsirolimus.

6.2 Incompatibilities
This medicinal product must not be mixed with other medicinal products, except those mentioned in
section 6.6.
21
TORISEL 30 mg concentrate must not be added directly to aqueous infusion solutions. Direct addition
of TORISEL 30 mg concentrate to aqueous solutions will result in precipitation of medicinal product.
Always dilute TORISEL 30 mg concentrate with 1.8 ml of the supplied diluent before adding to the
infusion solution. The concentrate-diluent mixture may only be administered in sodium chloride
9 mg/ml (0.9%) solution for injection.
TORISEL, when diluted, contains polysorbate 80, which is known to increase the rate of
di-(2-ethylhexyl) phthalate extraction (DEHP) from polyvinyl chloride (PVC). This incompatibility
has to be considered during the preparation and administration of TORISEL. It is important that the
recommendations in sections 4.2 and 6.6 be followed closely.
PVC bags and medical devices must not be used for the administration of preparations containing
polysorbate 80, because polysorbate 80 leaches DEHP from PVC.
6.3 Shelf life
2 years.
After first dilution of TORISEL 30 mg concentrate with 1.8 ml of withdrawn diluent: 24 hours when
stored below 25°C and protected from light.
After further dilution of the concentrate-diluent mixture with sodium chloride 9 mg/ml (0.9%) solution
for injection: 6 hours when stored below 25°C and protected from light.
6.4 Special precautions for storage
Store in a refrigerator (2°C-8°C).
Do not freeze.
Keep the vials in the outer carton in order to protect from light.
For storage conditions of the diluted medicinal product, see section 6.3.
6.5 Nature and contents of container
TORISEL 30 mg concentrate:
Clear glass vial (type 1 glass) with butyl rubber stopper and a plastic flip-top closure sealed with
aluminum.
Diluent:
Clear glass vial (type 1 glass) with butyl rubber stopper and a plastic flip-top closure sealed with
aluminum.
Pack size: 1 vial of 1.2 ml of concentrate and 1 vial of 2.2 ml of diluent.
6.6 Special precautions for disposal and other handling
During handling and preparation of admixtures, TORISEL should be protected from excessive room
light and sunlight.
TORISEL, when diluted, contains polysorbate 80, which is known to increase the rate of
di-(2-ethylhexyl) phthalate (DEHP) extraction from polyvinyl chloride (PVC).
22
Therefore, PVC bags and medical devices must not be used for the preparation, storage and
administration of TORISEL solutions for infusions.
Bags/containers that come in contact with TORISEL must be made of glass, polyolefin, or
polyethylene.
Dilution
TORISEL 30 mg concentrate must be diluted with the supplied diluent before administration in
sodium chloride infusion.
Note: For mantle cell lymphoma, multiple vials will be required for each dose over 25 mg. Each vial
of TORISEL must be diluted according to the instructions below. The required amount of concentrate-
diluent mixture from each vial must be combined in one syringe for rapid injection into 250 ml of
sodium chloride 9 mg/ml (0.9%) solution for injection (see section 4.2).
In preparing the solution, the following two-step process must be carried out in an aseptic manner
according to local standards for handling cytotoxic/cytostatic drugs:
STEP 1 : DILUTION OF TORISEL 30 mg CONCENTRATE WITH THE SUPPLIED DILUENT
Withdraw 1.8 ml of the supplied diluent.
Inject the 1.8 ml of diluent into the vial of TORISEL 30 mg concentrate.
Mix the diluent and the concentrate well by inversion of the vial. Sufficient time should be
allowed for air bubbles to subside. The solution should be a clear to slightly turbid, colourless
to light-yellow to yellow solution, essentially free from visual particulates.
One vial of TORISEL concentrate contains 30 mg of temsirolimus: when the 1.2 ml concentrate is
combined with 1.8 ml of withdrawn diluent, a total volume of 3.0 ml is obtained, and the concentration
of temsirolimus will be 10 mg/ml. The concentrate-diluent mixture is stable below 25°C for up to 24
hours.
STEP 2: ADMINISTRATION OF CONCENTRATE-DILUENT MIXTURE IN SODIUM
CHLORIDE INFUSION
Withdraw the required amount of concentrate-diluent mixture (containing temsirolimus
10 mg/ml) from the vial; i.e., 2.5 ml for a temsirolimus dose of 25 mg.
Inject the withdrawn volume rapidly into 250 ml of sodium chloride 9 mg/ml (0.9%) solution
for injection to ensure adequate mixing.
The admixture should be mixed by inversion of the bag or bottle, avoiding excessive shaking, as this
may cause foaming.
The resulting solution should be inspected visually for particulate matter and discolouration prior to
administration, whenever solution and container permit. The admixture of TORISEL in sodium
chloride 9 mg/ml (0.9%) solution for injection should be protected from excessive room light and
sunlight.
Administration
• Administration of the final diluted solution should be completed within six hours from the time that
the TORISEL is first added to sodium chloride 9 mg/ml (0.9%) solution for injection.
• TORISEL is infused over a 30- to 60-minute period once weekly. The use of an infusion pump is the
preferred method of administration to ensure accurate delivery of the medicinal product.
23
• Appropriate administration materials must be composed of glass, polyolefin, or polyethylene to avoid
excessive loss of medicinal product and to decrease the rate of DEHP extraction. The administration
materials must consist of non-DEHP, non-PVC tubing with appropriate filter. An in-line
polyethersulfone filter with a pore size of not greater than 5 microns is recommended for
administration to avoid the possibility of particles bigger than 5 microns being infused. If the
administration set available does not have an in-line filter incorporated, a filter should be added at the
end of the set (i.e., an end-filter) before the admixture reaches the vein of the patient. Different
end-filters can be used ranging in filter pore size from 0.2 microns up to 5 microns. The use of both an
in-line and end-filter is not recommended.
• TORISEL, when diluted, contains polysorbate 80, which is known to increase the rate of DEHP
extraction from PVC. This should be considered during the preparation and administration of
TORISEL following constitution. It is important that the recommendations in section 4.2 be followed
closely.
Disposal
Any unused product or waste material should be disposed of in accordance with local requirements.

6. Further information
1.
WHAT TORISEL IS AND WHAT IT IS USED FOR
Your doctor has prescribed TORISEL because you have one of the following types of cancer:
-
Advanced cancer of the kidney (renal cancer).
-
Previously treated mantle cell lymphoma, a type of cancer affecting the lymph nodes
TORISEL is a selective inhibitor of mTOR (mammalian target of rapamycin) that blocks tumour cell
growth and division.
2.
BEFORE YOU RECEIVE TORISEL
Do not use TORISEL
-
If you are allergic (hypersensitive) to temsirolimus, to polysorbate 80 or any of the other
ingredients of TORISEL
-
If you are allergic (hypersensitive) to sirolimus (used to prevent the body from rejecting
transplanted kidneys) since sirolimus is released from temsirolimus in the body.
-
If you have mantle cell lymphoma and liver problems please tell your doctor.
Take special care with TORISEL
-
If you are allergic (hypersensitive) to antihistamines or cannot take antihistamines for other
medical reasons.
-
If you have high cholesterol, TORISEL may elevate triglycerides and/or cholesterol. This may
require treatment with lipid-lowering agents (medicine used to reduce cholesterol in the blood).
-
If you are going to have an operation, if you have had recent major surgery, or if you still have
an unhealed wound following surgery, you should tell your doctor before receiving this
medicine, as TORISEL may increase the risk of problems with wound healing.
-
If you are planning to have a vaccination during treatment with TORISEL, the vaccination may
be less effective. The use of certain vaccinations should be avoided during treatment with
TORISEL.
-
If you have a history of kidney failure or kidney problems.
34
-
Keep this leaflet. You may need to read it again.
-
If you have a history of liver problems.
-
If you are a child or adolescent under 18 years of age, your doctor will consider the potential
benefit to you in relation to any risk.
-
If you are over 65 years of age, you may be more likely to have certain side effects, including
swelling of your face, diarrhoea, pneumonia, anxiety, depression, shortness of breath, decreased
number of white cells in the blood, muscle pain, change in the sense of taste, upper respiratory
infection, fluid around the lungs, sores and inflammation in the mouth and/or the digestive tract
and runny nose, dizziness and infections.
-
If you have tumours in your brain or spinal cord, or are taking medicines to prevent your blood
from clotting (such as warfarin), you may be more likely to have bleeding into your brain.
TORISEL may also
-
increase blood glucose levels and worsen diabetes mellitus. This may result in the need for
insulin and/or oral antidiabetic agent therapy. Tell your doctor if you experience any excessive
thirst or increased frequency and quantity of urination.
-
weaken your immune system; therefore, you may be at risk of getting an infection while you are
taking TORISEL.
-
cause shortness of breath, cough, and fever. Tell your doctor if you experience new or
worsening symptoms.
-
increase the risk of cerebral haemorrhage (bleeding in the brain).
-
cause cataracts when taken with interferon-α (a medicine used in the treatment of hepatitis and
cancer).
-
cause serious allergic reactions. Tell your doctor if you experience difficulty in breathing and/or
swelling of the face.
-
cause a decrease in the number of cells that help blood to clot, which may increase the risk of
bleeding.
Using TORISEL with other medicines
Some medicines can interfere with the breakdown or metabolism of TORISEL. In particular, you
should inform your doctor if you are taking any of the following:
-
protease inhibitors used in the treatment of HIV
-
antibiotics (including rifampicin) or antifungal medicines (including ketoconazole) used to treat
infections
-
nefazodone or selective serotonin re-uptake inhibitors used to treat depression
-
anti-epileptic medicines, including carbamazepine, phenytoin and phenobarbital
-
herbal medicines or natural remedies containing St. John’s Wort ( Hypericum perforatum ) used
to treat mild depression
-
Angiotensin converting enzyme (ACE) inhibitors used to treat high blood pressure or other
cardiovascular problems (such as enalapril, ramipril, lisinopril), amphiphilic medicines used to
treat heart arrhythmias (such as amiodarone), or statins used to treat high cholesterol
Using TORISEL with food and drink
-
Grapefruit juice may increase blood concentrations of TORISEL and should be avoided.
Please tell your doctor if you are taking, or have recently taken, any other medicines, including
medicines obtained without a prescription.
Pregnancy and breast-feeding
TORISEL has not been studied in pregnant women, and it must not be used during pregnancy. It is
important that you tell your doctor if you are pregnant or are planning to become pregnant before
receiving TORISEL.
35
-
rifabutin used to treat infection in people with HIV and other diseases
Women of childbearing potential must avoid pregnancy by using an effective method of birth control
during treatment with TORISEL. Men with partners of childbearing potential should use medically
acceptable contraception while receiving TORISEL.
Women should not breast-feed during treatment with TORISEL, as this medicine may interfere with
the growth and development of the baby. Ask your doctor for advice before breast-feeding your baby,
as it is not known if TORISEL passes into breast milk.
Driving and using machines
No studies on the ability to drive and use machines have been performed. However, the very common
side effects include feeling or being sick (nausea and vomiting) and difficulty falling or staying asleep.
It is recommended you do not drive immediately after treatment.
For patients receiving the higher dose of TORISEL for the treatment of mantle cell lymphoma,
the amount of alcohol in this medicinal product may impair your ability to drive or use machines.
Important information about some of the ingredients of TORISEL

3.
HOW TORISEL IS GIVEN
TORISEL will always be prepared and given to you by a doctor or another healthcare professional as
an intravenous infusion (into your vein).
TORISEL 30 mg concentrate must first be diluted with 1.8 ml of withdrawn diluent to achieve a
concentration of 10 mg/ml before administration in sodium chloride 9 mg/ml (0.9%) solution for
injection (see dilution instructions at the end of the package leaflet).
For renal cancer, the recommended dose is 25 mg infused (as a drip) over a 30- to 60-minute period
once weekly.
For mantle cell lymphoma, the recommended dosing is 175 mg infused (as a drip) over a
30- to 60-minute period once weekly for 3 weeks followed by single weekly doses of 75 mg infused
(as a drip) over a 30- to 60-minute period.
You should receive an injection of antihistamine (to try to prevent allergic reaction to TORISEL)
directly into your vein approximately 30 minutes before your dose of TORISEL.
Treatment with TORISEL should continue until you are no longer benefiting from therapy or until
unacceptable side effects occur.
36
If too much TORISEL is given or you miss a dose
As this medicine is prepared and given by a healthcare professional, it is unlikely you will be given too
much.
If you are concerned about this, or think you may have missed a dose, tell your doctor immediately.
4.

__________________________________________________________________________________
The following information is intended for medical or healthcare professionals only:
During handling and preparation of admixtures, TORISEL should be protected from excessive room
light and sunlight.
Bags/containers that come in contact with TORISEL must be made of glass, polyolefin, or
polyethylene.
Polyvinyl chloride (PVC) bags and medical devices must not be used for the administration of
preparations containing polysorbate 80, because polysorbate 80 leaches di-2-ethylhexylphthalate
(DEHP) from PVC.
Dilution
TORISEL 30 mg concentrate must be diluted with 1.8 ml of withdrawn diluent before
administration in sodium chloride 9 mg/ml (0.9%) solution for injection.
Note: For mantle cell lymphoma, multiple vials will be required for each dose over 25 mg. Each vial
of TORISEL must be diluted according to the instructions below. The required amount of concentrate-
diluent mixture from each vial must be combined in one syringe for rapid injection into 250 ml of
sodium chloride 9 mg/ml (0.9%) solution for injection.
In preparing the solution, the following two-step process must be carried out in an aseptic manner
according to local standards for handling cytotoxic/cytostatic drugs:
STEP 1 : DILUTION OF CONCENTRATE WITH THE SUPPLIED DILUENT
Withdraw 1.8 ml of the supplied diluent.
Inject the 1.8 ml of extracted diluent into the vial of TORISEL 30 mg concentrate.
Mix the diluent and the concentrate well by inversion of the vial. Sufficient time should be
allowed for air bubbles to subside. The solution should be a clear to slightly turbid, colourless
to light-yellow to yellow solution, essentially free from visual particulates.
One vial of TORISEL 30 mg concentrate contains 30 mg of temsirolimus: when the 1.2 ml concentrate
is combined with 1.8 ml of withdrawn diluent, a total volume of 3.0 ml is obtained and the
concentration of temsirolimus will be 10 mg/ml. The concentrate-diluent mixture is stable below 25°C
for up to 24 hours.
STEP 2 : ADMINISTRATION OF CONCENTRATE-DILUENT MIXTURE IN SODIUM
CHLORIDE INFUSION
Withdraw the required amount of concentrate-diluent mixture (which contains temsirolimus
10 mg/ml) from the vial; i.e., 2.5 ml for a temsirolimus dose of 25 mg.
Inject the withdrawn volume rapidly into 250 ml of sodium chloride 9 mg/ml (0.9%) solution
for injection to ensure adequate mixing.
The admixture should be mixed by inversion of the bag or bottle, avoiding excessive shaking, as this
may cause foaming.
The resulting solution should be inspected visually for particulate matter and discolouration prior to
administration, whenever solution and container permit. The admixture of TORISEL in sodium
chloride 9 mg/ml (0.9%) solution for injection should be protected from excessive room light and
sunlight.
For mantle cell lymphoma, multiple vials will be required for each dose over 25 mg.
41
Administration
• Administration of the final diluted solution should be completed within six hours from the time that
the TORISEL is first added to sodium chloride 9 mg/ml (0.9%) solution for injection.
• TORISEL is infused over a 30- to 60-minute period once weekly. The use of an infusion pump is the
preferred method of administration to ensure accurate delivery of the medicinal product.
• Appropriate administration materials must be composed of glass, polyolefin, or polyethylene to avoid
excessive loss of medicinal product and to decrease the rate of DEHP extraction. The administration
materials must consist of non-DEHP, non-PVC tubing with appropriate filter. An in-line
polyethersulfone filter with a pore size of not greater than 5 microns is recommended for
administration to avoid the possibility of particles bigger than 5 microns being infused. If the
administration set available does not have an in-line filter incorporated, a filter should be added at the
end of the set (i.e., an end-filter) before the admixture reaches the vein of the patient. Different
end-filters can be used ranging in filter pore size from 0.2 microns up to 5 microns. The use of both an
in-line and end-filter is not recommended.
• TORISEL, when diluted, contains polysorbate 80, which is known to increase the rate of DEHP
extraction from PVC. This incompatibility has to be considered during the preparation and
administration of TORISEL. It is important that the recommendations in sections 4.2 and 6.6 in the
SPC be followed closely.
Disposal
Any unused product or waste material should be disposed of in accordance with local requirements.
