Summary for the public


What is Cayston?

Cayston is a powder and solvent that are made up into a nebuliser solution. It contains the active substance aztreonam.


What is Cayston used for?

Cayston is used to suppress long-term lung infection caused by P. aeruginosa bacteria in adults (aged 18 years or over) with cystic fibrosis. Cystic fibrosis is an inherited disease that affects the cells in the lungs and the glands in the gut and pancreas that secrete fluids such as mucus and digestive juices.

Because the number of patients with bacterial lung infection in cystic fibrosis is low, the disease is considered ‘rare’, and Cayston was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 21 June 2004.

 The medicine can only be obtained with a prescription.


How is Cayston used?

Cayston is to be used with a nebuliser (a special machine that changes the solution into an aerosol that the patient can breathe in). Cayston is given three times a day for four weeks, with at least four hours between each dose. A bronchodilator (a medicine that widens the airways in the lungs) should be used before each dose of Cayston. If the doctor thinks that further treatment with Cayston is needed after the first course, a gap of at least four weeks is recommended before any additional Cayston is given.


How does Cayston work?

In cystic fibrosis, the patient’s lungs produce too much thick mucus, which allows bacteria to grow more easily. In patients with cystic fibrosis, P. aeruginosa infections usually start in the first 10 years of life and can cause long-term lung problems.

The active substance in Cayston, aztreonam, is an antibiotic that belongs to the group ‘beta-lactams’. It works by attaching to proteins on the surface on the surface of the P. aeruginosa bacteria. This prevents the bacteria from building their cell walls, which kills them.

Aztreonam has been available as an injection since the 1980s as an ‘arginine salt’. In Cayston, aztreonam is available as a ‘lysine salt’, which makes it possible for the antibiotic to be breathed directly into the lungs without causing irritation.


How has Cayston been studied?

Cayston was compared with placebo (a dummy treatment) in two main studies involving a total of 375 patients with cystic fibrosis, most of whom were adults. The patients were treated for four weeks. In the first study, the main measure of effectiveness was how long it took before the patients needed other antibiotics by inhalation or injection into a vein. In the other study, the main measure of effectiveness was how the patients rated their respiratory symptoms on a standard scale for cystic fibrosis.

An additional study compared four weeks of Cayston with placebo in patients with mild lung disease due to cystic fibrosis. It looked at how well the lungs worked, the amount of P. aeruginosa bacteria in the patients’ mucus and their respiratory symptoms.


What benefit has Cayston shown during the studies?

Cayston was more effective than placebo at suppressing lung infection caused by P. aeruginosa bacteria in adults with cystic fibrosis. In one study, the patients who received Cayston required other antibiotics after 92 days, compared with 71 days for the patients who received placebo. In the second study, respiratory symptoms improved in the patients who received Cayston, compared with the patients who received placebo.

The additional study produced results that were consistent with those of the two main studies.


What is the risk associated with Cayston?

The most common side effects with Cayston (seen in more than 1 patient in 10) are wheezing, cough, pharyngolaryngeal pain (pain in the throat and voice box), nasal congestion (blocked nose) and fever. For the full list of all side effects reported with Cayston, see the package leaflet.

Cayston should not be used in people who may be hypersensitive (allergic) to aztreonam or any of the other ingredients.


Why has Cayston been approved?

The CHMP concluded that there was an unmet medical need for new antibiotics in patients with cystic fibrosis, since many of these patients have already developed resistance to other antibiotics by the time they reach adulthood, and because P. aeruginosa lung infections are a cause of severe health problems in patients with cystic fibrosis. The CHMP decided that Cayston’s benefits are greater than its risks and recommended that it be given marketing authorisation.

Cayston has been given ‘conditional approval’. This means that there is more evidence to come about the medicine, in particular on the repeated use of the medicine. This will confirm whether the benefits seen in the short-term studies will be sustained over several courses of treatment, and will provide information on Cayston’s long-term safety, in particular the development of resistance to aztreonamin P. aeruginosa. Every year, the European Medicines Agency will review any new information that may become available and this summary will be updated as necessary.

 


What information is still awaited for Cayston?

The company that makes Cayston will carry out long-term studies of Cayston including a study comparing Cayston with nebulised tobramycin (another antibiotic) and studies in children.


Other information about Cayston:

The European Commission granted a conditional marketing authorisation valid throughout the European Union for Cayston to Gilead Sciences International Limited on 21 September 2009. After a year, the conditional marketing authorisation was renewed for a further year.

For more information about treatment with Cayston, read the package leaflet (also part of the EPAR) or contact your doctor or pharmacist.

Authorisation details
Name: Cayston
EMEA Product number: EMEA/H/C/000996
Active substance: aztreonam lysine
INN or common name: aztreonam
Therapeutic area: Respiratory Tract InfectionsCystic Fibrosis
ATC Code: J01DF01
Treatment of rare diseases: This medicine has an "orphan designation" which means that it is used to treat life-threatening or chronically debilitating conditions that affect no more than five in 10,000 people in the European Union, or are medicines which, for economic reasons, would be unlikely to be developed without incentives.
Conditional Approval: Sometimes, the CHMP recommends that a medicine be given ‘conditional approval’. This happens when the Committee has based its positive opinion on data which, while not yet comprehensive, indicate that the medicine’s benefits outweigh its risks.The company is given obligations to fulfil, such as the performance of further studies. The approval is renewed on a yearly basis until all obligations have been fulfilled, and is then converted from a conditional approval into a normal approval. Conditional approvals can only be granted for medicines that satisfy an ‘unmet medical need’, meaning the medicine is intended to be used for a disease or condition for which no treatment is readily available, and it is therefore important that patients have early access to the medicine concerned.

Product Characteristics

ANNEX I

SUMMARY OF PRODUCT CHARACTERISTICS


1.
NAME OF THE MEDICINAL PRODUCT
Cayston 75 mg powder and solvent for nebuliser solution
2.
QUALITATIVE AND QUANTITATIVE COMPOSITION
Cayston contains aztreonam lysine (formed in situ from 75 mg aztreonam) as a sterile lyophilised
powder in a vial and a 1 ml ampoule of sterile solvent (0.17% w/v sodium chloride). After
reconstitution of the powder in the solvent, the nebuliser solution contains 75 mg aztreonam (as
lysine).
For a full list of excipients, see section 6.1.
3.
PHARMACEUTICAL FORM
Powder and solvent for nebuliser solution.
White to off-white, lyophilised powder.
4.
CLINICAL PARTICULARS
4.1 Therapeutic indications
Cayston is indicated for the suppressive therapy of chronic pulmonary infections due to Pseudomonas
aeruginosa in patients with cystic fibrosis (CF) aged 18 years and older.
The primary support for this indication is based on two single 28-day course placebo-controlled
studies. The data to support the sustainability of the observed short term benefit over subsequent
courses of treatment are limited (see section 5.1). Consideration should be given to official guidance
on the appropriate use of antibacterial agents.
4.2 Posology and method of administration
Patients should use a bronchodilator before each dose of Cayston. Short acting bronchodilators can be
taken between 15 minutes and 4 hours and long acting bronchodilators can be taken between
30 minutes and 12 hours prior to each dose of Cayston.
For patients receiving several respiratory therapies, the recommended order is:
1.
bronchodilator
2.
chest physiotherapy
4.
other inhaled medicinal products
5.
Cayston.
Adults
The recommended dose for adults is 75 mg three times per 24 hours for 28 days.
Doses should be taken at least 4 hours apart.
Multiple course, controlled efficacy data are not yet available (see section 5.1). Additional courses,
beyond the initial 28-day course, should be considered only at the discretion of the physician. If
additional courses are prescribed, a minimum of 28 days without Cayston is recommended.
2
3.
dornase alfa
Paediatric population
Cayston is not recommended for use in children below the age of 18 years due to insufficient data on
safety and efficacy (see section 5.1).
Elderly population
Clinical studies with Cayston did not include sufficient numbers of patients aged 65 years and over to
determine whether they responded differently from younger patients. If Cayston is to be prescribed to
the elderly then the posology is the same as for adults.
Renal impairment
Aztreonam is known to be excreted renally and therefore administration of Cayston in patients with
renal impairment (serum creatinine > 2 times upper limit of normal) should be undertaken with
caution. No dose adjustment is necessary in cases of renal impairment since the systemic
concentration of aztreonam following inhaled administration of Cayston is very low (approximately
1% of the concentration resulting from a dose of 500 mg aztreonam for injection).
Hepatic impairment
There are no data on the use of Cayston in patients with severe hepatic impairment (ALT or AST
greater than 5 times the upper limit of normal). No dose adjustment is necessary in cases of hepatic
impairment.
Method of administration
Cayston is only for inhalation use.
Cayston should only be used with the Altera Nebuliser Handset and Altera Aerosol Head connected to
an Altera Control Unit or an eFlow rapid Control Unit. For instructions on reconstitution of the
medicinal product before administration, see section 6.6.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients.
4.4 Special warnings and precautions for use
Allergic reactions
If an allergic reaction to Cayston does occur, stop administration of the medicinal product and initiate
treatment as appropriate. The occurrence of rash may be indicative of an allergic reaction to Cayston.
Cross-reactivity may occur in patients with a history of allergy to beta-lactam antibiotics, such as
penicillins, cephalosporins, and/or carbapenems. Animal and human data demonstrate low risk of
cross-reactivity between aztreonam and beta-lactam antibiotics. Aztreonam, a monobactam, is only
weakly immunogenic. Caution is advised when administering Cayston to patients if they have a
history of beta-lactam allergy.
The following rare and severe adverse reactions, although these have not been observed to date with
Cayston, have been reported after parenteral use of other aztreonam containing products: toxic
epidermal necrolysis, anaphylaxis, purpura, erythema multiforme, exfoliative dermatitis, urticaria,
petechiae, pruritus, diaphoresis.
3
Bronchospasm
Bronchospasm is a complication associated with nebulised therapies. Patients were pre-treated with a
bronchodilator before dosing with study therapy. An acute reduction of ≥ 15% in forced expiratory
volume in 1 second (FEV 1 ) following administration of study therapy was observed in 3% of patients
treated with Cayston and 4% of patients receiving placebo despite pre-treatment with a bronchodilator
before dosing with study therapy. Patients should use a bronchodilator before each dose of Cayston.
If a case of bronchospasm is suspected to be part of an allergic reaction appropriate measures should
be taken (see “allergic reactions” paragraph above).
Other precautions
In clinical studies, the efficacy and safety of Cayston were not tested in patients with FEV 1 %
predicted < 25% or > 75%. Patients with Burkholderia cepacia isolated from sputum within the
previous 2 years were excluded from the clinical studies.
Aztreonam for injection must not be used in the Altera or other nebulisers. Aztreonam for injection
has not been formulated for inhalation, and contains arginine, a substance known to cause pulmonary
inflammation.
The development of antibiotic-resistant P. aeruginosa and superinfection with other pathogens
represent potential risks associated with antibiotic therapy. Development of resistance during inhaled
aztreonam therapy could limit treatment options during acute exacerbations. In clinical studies of
Cayston, no increases of clinical significance were observed in the prevalence of antibiotic-resistant
P. aeruginosa or other bacterial respiratory pathogens among patients treated three times daily with
Cayston. Among patients with multidrug-resistant P. aeruginosa , improvements in respiratory
symptoms and pulmonary function were observed following treatment with Cayston. An increased
prevalence of Aspergillus and Candida species were observed over time in patients treated with
several Cayston treatment courses. The clinical significance of this finding is unknown.
4.5 Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed. However, no evidence of any drug interactions with
Cayston were identified from clinical studies in which Cayston was taken concomitantly with
bronchodilators, dornase alfa, pancreatic enzymes, azithromycin, tobramycin, oral steroids (less than
10 mg daily/20 mg every other day) and inhaled steroids.
4.6 Pregnancy and lactation
There are no data from the use of aztreonam in pregnant women. Animal studies do not indicate direct
or indirect harmful effects with respect to reproductive toxicity (see section 5.3).
Systemic concentration of aztreonam following inhaled administration of Cayston is low compared to
a standard dose of aztreonam for injection (approximately 1% of the concentration resulting from a
dose of 500 mg aztreonam for injection).
Cayston should not be used during pregnancy unless the clinical condition of the woman requires
treatment with aztreonam.
Following administration of aztreonam for injection, aztreonam is excreted in human milk at very low
concentrations. Systemic concentration of aztreonam following inhaled administration of Cayston is
approximately 1% of the concentration resulting from a standard dose of aztreonam for injection.
Therefore, and because of low oral absorption, aztreonam exposure in breast-fed infants due to
mothers receiving Cayston is likely to be extremely low.
Cayston can be used during breast-feeding.
4
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. However,
based on the safety profile and mechanism of action, Cayston is not expected to adversely affect the
ability to drive or use machines.
4.8 Undesirable effects
The safety of Cayston was evaluated in three Phase 3 studies in 344 predominantly adult patients
(77%) with chronic P. aeruginosa . In two Phase 3 placebo-controlled studies patients received
Cayston 75 mg 2 times (69 patients) or 3 times a day (146 patients) for 28 days. In one Phase 3 open-
label follow-on study 274 CF patients received up to nine 28-day treatment courses of Cayston 75 mg
2 times or 3 times a day.
The adverse reactions with suspected (at least possible) relationship to treatment in the placebo-
controlled studies are listed below by body system organ class and frequency.
Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.
Frequencies are defined as follows: very common (≥ 1/10) and common (≥ 1/100 to < 1/10).
Respiratory, thoracic and mediastinal disorders
Very common: wheezing, cough, pharyngolaryngeal pain, nasal congestion
Common: non-allergic bronchospasm, chest discomfort, rhinorrhoea
Skin and subcutaneous tissue disorders
Common: rash
General disorders and administration site conditions
Very common: pyrexia
The following rare and severe adverse reactions, although these have not been observed to date with
Cayston, have been reported after parenteral use of other aztreonam containing products: toxic
epidermal necrolysis, anaphylaxis, purpura, erythema multiforme, exfoliative dermatitis, urticaria,
petechiae, pruritus, diaphoresis.
4.9 Overdose
Adverse reactions specifically associated with overdose of Cayston have not been identified. Since
the plasma concentration of aztreonam following administration of Cayston (75 mg) is approximately
0.6 µg/ml, compared to serum levels of 54 µg/ml following administration of aztreonam for injection
(500 mg), no safety issues associated with Cayston overdose are anticipated.
5.
PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antibacterials for systemic use, other beta-lactam antibacterials, ATC
code: J01DF01
Mechanism of action
Aztreonam exhibits activity in vitro against gram-negative aerobic pathogens, including
P. aeruginosa . Aztreonam binds to penicillin-binding proteins of susceptible bacteria, which leads to
inhibition of bacterial cell wall synthesis, followed by filamentation and cell lysis.
5
Mechanisms of resistance
Loss of susceptibility to aztreonam in CF patients with P. aeruginosa occurs either through selection
of strains with mutations located on the chromosome or rarely through acquisition of plasmid/integrin
mediated genes.
Known mechanisms of resistance to aztreonam mediated by mutation of chromosomal genes include:
hyperexpression of the Class C beta-lactamase AmpC and up-regulation of the efflux pump
MexAB-OprM. The known mechanism of resistance to aztreonam mediated by acquisition of genes
involves acquisition of extended spectrum beta-lactam enzymes (ESBLs) that hydrolyse the four-
member, nitrogen-containing ring of aztreonam.
ESBLs from Class A, B and D beta-lactamases generally have little or no activity against aztreonam.
Class A beta-lactamases reported to hydrolyse aztreonam include the VEB type (primarily Southeast
Asia), PER type (Turkey), and GES and IBC types (France, Greece, and S. Africa). There are rare
reports of organisms with metallo-beta-lactamases (MBLs), Class B, that are resistant to aztreonam,
VIM-5 ( K. pneumoniae and P. aeruginosa - Turkey), VIM-6 ( P. putida - Singapore) and VIM-7
( P. aeruginosa - United States), however, it is possible that these organisms were expressing multiple
resistance mechanisms and thus a MBL was not responsible for the observed resistance to aztreonam.
There are rare reports of Class D beta-lactamases from clinical isolates of P. aeruginosa , OXA-11
(Turkey) and OXA-45 (United States) that hydrolyse aztreonam.
Microbiology
A single sputum sample from a CF patient may contain multiple isolates of P. aeruginosa and each
isolate may have a different level of in vitro susceptibility to aztreonam. The in vitro antimicrobial
susceptibility test methods used for parenteral aztreonam therapy can be used to monitor the
susceptibility of P. aeruginosa isolated from CF patients.
In the Phase 3 placebo-controlled studies of Cayston, local aztreonam concentrations generally
exceeded aztreonam MIC values for P. aeruginosa , regardless of the level of P. aeruginosa
susceptibility.
Treatment with a 28-day course of 75 mg 3 times a day Cayston therapy resulted in clinically
important improvements in respiratory symptoms, pulmonary function, and sputum P. aeruginosa
CFU density, regardless of whether the highest aztreonam MIC for P. aeruginosa was above or below
the established susceptibility breakpoint for intravenous aztreonam administration (8 µg/ml). Based
on categorical analyses of the relationship between MIC and treatment response, a susceptibility
breakpoint for Cayston cannot be established. Over 6 courses of Cayston therapy, P. aeruginosa
MIC 50 and MIC 90 did not change (± 2 dilution change), however there is a theoretical risk that patients
treated with Cayston may develop P. aeruginosa isolates resistant to aztreonam or other beta-lactam
antibiotics.
In studies of up to six 28-day courses of Cayston therapy, no increases of clinical significance have
been observed in the treatment-emergent isolation of other bacterial respiratory pathogens
( Stenotrophomonas maltophilia, Alcaligenes xylosoxidans, and Staphylococcus aureus ).
Clinical Experience:
Cayston was evaluated over a period of 28-days of treatment (one course) in two randomised, double-
blind, placebo-controlled, multicentre studies (CP-AI-005 and CP-AI-007). Patients participating in
these studies could subsequently receive multiple courses of Cayston in an open-label follow-on study
(CP-AI-006). Entry criteria included CF baseline FEV 1 % predicted between 25% and 75% and
chronic P. aeruginosa lung infection. Overall, 344 predominantly adult patients (77%) were treated in
these studies. Studies were conducted using the Altera Nebuliser System.
6
CP-AI-007
CP-AI-007 enrolled 164 adult (predominantly) and paediatric patients randomised in a 1:1 ratio
comparing inhaled Cayston 75 mg (80 patients) or placebo (84 patients) administered 3 times a day for
28-days (one course). Patients were required to have been off antipseudomonal antibiotics for at least
28 days before treatment with study drug.
Pulmonary function and respiratory symptoms significantly improved from baseline to Day 28 in
patients treated with one course of Cayston.
CP-AI-005
CP-AI-005 enrolled 246 adult (predominantly) and paediatric patients. All patients were treated with
Tobramycin Nebuliser Solution (TNS) 300 mg, 2 times a day in the four weeks immediately prior to
receiving Cayston or placebo either 2 or 3 times a day for 28 days. Patients continued on their
baseline medications, including macrolide antibiotics. Patients were randomised in a 2:2:1:1 ratio to
be treated with Cayston 75 mg 2 or 3 times a day or volume-matched placebo 2 or 3 times a day for
28 days immediately following the 28-day lead-in course of open-label TNS.
Cayston therapy resulted in significant improvements in pulmonary function and respiratory
symptoms at Day 28 in the 66 patients treated with one course Cayston 75 mg 3 times a day.
CP-AI-006
CP-AI-006 was an open-label follow-on study to CP-AI-005 and CP-AI-007 evaluating the safety of
repeated exposure to Cayston and the effect on disease-related endpoints over multiple 28-day courses.
Patients received Cayston at the same frequency (2 or 3 times a day) as they took Cayston or placebo
in the randomised studies. Patients continued on their baseline medications and whenever indicated
additional antibiotics were used in the majority of patients to treat exacerbations. Each 28-day course
of Cayston was followed by a 28-day off drug period. Over six 28-day courses of therapy, measures
of pulmonary function (FEV 1 ), CFQ-R respiratory symptoms scores, and log 10 P. aeruginosa CFUs
showed a trend to improvement while the patients were on treatment compared with off treatment.
However, due to the uncontrolled nature of the study and concomitant medications no conclusion can
be drawn on the sustainability of the observed short term benefit over subsequent courses of treatment.
This medicinal product has been authorised under a so-called “conditional approval” scheme.
This means that further evidence on this medicinal product is awaited.
The European Medicines Agency will review new information on the product every year and this
SmPC will be updated as necessary.
5.2 Pharmacokinetic properties
Absorption
Sputum concentrations
Individual patients’ sputum aztreonam concentrations exhibited considerable variability. For the
combined Phase 3 placebo-controlled studies, ten minutes following a single dose of 75 mg Cayston
on Days 0, 14, and 28, the mean sputum concentrations in 195 patients with CF were 726 µg/g,
711 µg/g, and 715 µg/g, respectively, indicating no increased accumulation of aztreonam following
repeated dosing.
Plasma concentrations
Individual patients’ plasma aztreonam concentrations exhibited considerable variability. One hour
following a single dose of 75 mg Cayston (at approximately peak plasma concentration), the mean
plasma level in patients with CF was 0.59 µg/ml. Mean peak plasma levels at Days 0, 14, and 28 of a
7
course with 75 mg Cayston 3 times a day were 0.55 µg/ml, 0.67 µg/ml, and 0.65 µg/ml, respectively,
indicating no systemic accumulation of aztreonam following 3 times a day dosing. In contrast, the
serum concentration of aztreonam following administration of aztreonam for injection (500 mg) is
approximately 54 µg/ml.
Elimination
The elimination half-life of aztreonam from serum is approximately 2.1 hours following inhalation
administration, similar to what has been reported for aztreonam for injection. Systemically absorbed
aztreonam is eliminated by both active tubular secretion and glomerular filtration.
Pharmacokinetics in special populations
Age and gender
There was no clinically relevant effect of age or sex on the pharmacokinetics of Cayston.
Renal and hepatic impairment
Pharmacokinetic studies have not been performed in patients with renal or hepatic impairment.
Pharmacokinetic properties for aztreonam for injection
Peak levels of aztreonam are achieved at about one hour after i.m. administration. After identical
single i.m. or i.v. doses, the serum concentrations are comparable at 1 hour (1.5 hours from the start of
i.v. infusion), with similar slopes of serum concentrations thereafter. The serum half-life of aztreonam
averaged 1.7 hours in subjects with normal renal function, independent of the dose and route. In
healthy subjects 60-70% of a single i.m. or i.v. dose was recovered in the urine by 8 hours, and urinary
excretion was essentially complete by 12 hours.
5.3 Preclinical safety data
A 104-week rat inhalation toxicology study to assess the carcinogenic potential of ascending doses
(31, 56 and 120 mg/kg/day) of Cayston demonstrated no drug-related increase in malignant tumours.
The only evidence of Cayston-related carcinogenicity was a small increase in the incidence of benign
C-cell adenomas in females at 120 mg/kg/day. The clinical relevance of this effect is unknown. No
such added effect was observed at 56 mg/kg/day in which exposures exceeded 2.2 to 9 times the
human exposure, based on AUC or C max respectively.
Genotoxicity (Chromosomal aberration and mouse lymphoma mutation assay) studies with aztreonam
were negative indicating that the mechanism of benign C-cell adenomas in female rats was not
genotoxically mediated.
Fertility, teratology, perinatal and postnatal studies were conducted with aztreonam for injection in
rats at daily doses up to 750 mg/kg without adverse effects. The survival rate during the lactation
period was slightly reduced in the offspring of rats that received the highest dose.

Further information
1.
WHAT CAYSTON IS AND WHAT IT IS USED FOR
Cayston is an antibiotic used to suppress chronic lung infection caused by the bacteria Pseudomonas
aeruginosa in adult patients with cystic fibrosis. Cystic fibrosis, also known as mucoviscidosis, is a
life-threatening inherited disease that affects the mucus glands of internal organs, especially the lungs,
but also of the liver, pancreas, and the digestive system. Cystic fibrosis in the lungs leads to clogging
them with thick sticky mucus. This makes it hard to breathe.
2.
BEFORE YOU TAKE CAYSTON
Do not take Cayston
-
if you are allergic (hypersensitive) to aztreonam or any of the other ingredients of Cayston.
Take special care with Cayston
Your doctor needs to know:
- if you are allergic to any other antibiotics (such as penicillins, cephalosporins, and/or
carbapenems)
- if you do not tolerate or have chest tightness from taking other inhaled medicines
- if you have kidney problems.
If any of these apply to you tell your doctor before using Cayston.
Cayston is not for use in children under the age of 18.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
27
-
Keep this leaflet. You may need to read it again.
3.
How to take Cayston
Pregnancy and breast-feeding
It is important to tell your doctor if you are breast-feeding, if you are pregnant or planning to become
pregnant, or when you think you are pregnant. Your doctor will help you decide what is best for you
and your child.
There are no clinical data on the use of Cayston in pregnant women, therefore you should not take
Cayston during pregnancy unless specifically discussed with your doctor.
If you plan to breast-feed ask your doctor for advice before taking Cayston. You can breast-feed
during treatment with Cayston because the amount of Cayston likely to be passed to your child during
breast-feeding will be extremely small.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Cayston is not expected to affect your ability to drive or use machines.
3.
HOW TO TAKE CAYSTON
Always take Cayston exactly as your doctor has told you. You should check with your doctor or
pharmacist if you are not sure.
-
Take Cayston 3 times a day for the 28-day treatment course. Each of the three doses should
be taken by inhalation at least four hours apart, using an Altera Nebuliser Handset. You can use
either an Altera Control Unit or an eFlow rapid Control Unit with the Altera Handset.
-
Each dose consists of one vial of Cayston mixed with one ampoule of solvent. Cayston needs to
be mixed with a solvent before being inhaled through the Altera Nebuliser.
Put the prepared Cayston solution in the Altera Nebuliser Handset (see below). Each treatment takes
about 2 to 3 minutes to inhale.
Use a bronchodilator before each dose of Cayston. Short acting bronchodilators can be taken between
15 minutes and 4 hours and long acting bronchodilators can be taken between 30 minutes and 12 hours
prior to each dose of Cayston.
If you are using other therapies to treat cystic fibrosis, the recommended order is as follows:
1. bronchodilator
2. dornase alfa (a medicine that helps to dissolve the thick mucous produced in the lungs)
3. chest physiotherapy
4. any other inhaled medicines
and finally:
5.
Cayston.
Do not mix Cayston with any other medicines in the Altera Nebuliser Handset.
-
Do not put the intravenous (injectable) form of aztreonam in the Altera Nebuliser Handset.
Intravenous aztreonam is not suitable for inhalation.
28
-
Do not put other medicines in the Altera Nebuliser Handset.
How to take Cayston using the Altera Nebuliser Handset
You will need the following:
One amber-coloured vial of Cayston
One plastic ampoule of solvent (0.17% w/v sodium chloride)
An Altera Nebuliser Handset containing an Altera Aerosol Head connected to an Altera Control
Unit (678G) or an eFlow rapid Control Unit (178G)
You must use the Cayston specific Altera Nebuliser Handset containing an Altera Aerosol Head.
Do not try to take Cayston using any other type of nebuliser handset (including the eFlow rapid
handset).
Check that your nebuliser works properly before starting your treatment with Cayston. Read the
manufacturer’s instructions for use provided with your Altera Nebuliser System carefully.
Preparing your Cayston for inhalation
-
Do not prepare Cayston until you are ready to administer a dose.
-
Do not use Cayston if it has been stored outside a refrigerator for more than 28 days.
-
Do not use the solvent or prepared Cayston if it is cloudy or if there are particles in the solution.
1. Take one amber vial of Cayston and one ampoule of solvent from the box. Solvent ampoules
must be separated by gently pulling them apart.
2. Gently tap the amber vial containing the Cayston so that the powder settles at the bottom. This
helps to ensure that you get the proper dose of medicine.
3. Open the amber vial by lifting up the metal flap on the top (Figure 1a) and pulling down
(Figure 1b) to carefully remove the entire metal ring and overcap from the vial (Figure 1c). Safely
dispose of the ring. Carefully remove the rubber stopper.
4. Open the ampoule of solvent by twisting off the tip. Squeeze out the contents completely into the
vial (Figure 1d). Next, gently swirl the vial until the powder has completely dissolved and the
liquid is clear.
It’s best to use Cayston immediately after you have made up the solution. But, if you cannot use
the prepared dose straight away, replace the stopper in the vial and store in a refrigerator. Use the
prepared solution within 8 hours.
Preparing the Altera Nebuliser to take your Cayston
1. Make sure the Altera Nebuliser Handset is on a flat, stable surface.
2. Remove the medicine cap by twisting anticlockwise.
29
-
Do not use Cayston if you notice that the package has been tampered with.
 
3. Pour all of the prepared Cayston from the vial into the Altera Nebuliser Handset medicine
reservoir (Figure 2a). Be sure to completely empty the vial. Gently tap the vial against the side of
the medicine reservoir if necessary.
4. Close the medicine reservoir by aligning the tabs of the medicine cap with the slots on the
reservoir. Press down and turn the cap clockwise as far as it will go (Figure 2b).
Figure 2a
Figure 2b
Using the Altera Nebuliser to take your Cayston
1. Begin your treatment. Sit in a relaxed, upright position. Hold the handset level and place the
mouthpiece in your mouth and close your lips around it (Figure 3).
Figure 3
Keep the handset level.
2. Press and hold the On/Off button on the Control Unit for a few seconds. You will hear one
“beep” and the status light will turn green.
3. After a few seconds, an aerosol mist will begin to flow into the Aerosol Chamber of the Altera
Nebuliser Handset. If aerosol mist does not begin to flow, please refer to the Altera manual for
information.
30
4. Breathe normally (inhale and exhale) through the mouthpiece. Avoid breathing through your
nose. Continue to inhale and exhale comfortably until the treatment is finished.
5. When all of the medicine has been delivered, you will hear a tone that means “treatment
complete” (2 beeps).
6. When treatment is complete, open the medicine cap to ensure that all medicine has been used. A
few drops of medicine may remain in the reservoir at the end of treatment. If there is more than a
few drops of liquid left, replace the medicine cap and restart treatment.
7. Once treatment is complete, disconnect the Control Unit and take apart the Altera Nebuliser
Handset for cleaning and disinfecting. For complete details on cleaning and disinfecting refer to
the manufacturer’s instructions for use provided with your Altera Nebuliser Handset.
What if I need to stop my treatment before I’ve finished?
8. If for any reason you must stop the treatment before you have finished, press and hold the On/Off
button for one full second. To re-start the treatment, press and hold the On/Off button for one full
second and then restart the treatment.
Replacing the Altera Nebuliser Handset
The Altera Nebuliser Handset is designed to last for three 28-day courses of Cayston when used as
directed. After this time replace your Altera Nebuliser Handset, including the aerosol head. If you
notice that the performance has changed before this time (for instance, if it takes longer to produce a
mist, more than 5 minutes), please refer to the Altera Nebuliser instructions for use.
If you take more Cayston than you should
If you have taken more Cayston than you should, talk to a doctor or pharmacist immediately.
If you forget to take Cayston
If you miss a dose, you can still take all 3 daily doses as long as they are at least 4 hours apart. If you
can’t leave a gap of 4 hours just skip the missed dose.
If you want to stop taking Cayston
Do not stop taking Cayston without first talking to your doctor.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4.
