Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Bretaris Genuair.

What is in this leaflet

This leaflet answers some common questions about BRETARIS GENUAIR.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your pharmacist or doctor will be able to advise you about the risks and benefits of using BRETARIS GENUAIR.

If you have any concerns about using this medicine, ask your pharmacist or doctor.

Keep this leaflet with the medicine. You may need to read it again.

What BRETARIS GENUAIR is used for

The active ingredient of BRETARIS GENUAIR is aclidinium bromide, which belongs to a group of medicines called bronchodilators. Bronchodilators relax airways and help keep bronchioles open.

BRETARIS GENUAIR is a dry powder inhaler that uses your breath to deliver the medicine directly into your lungs. This makes it easier for chronic obstructive pulmonary disease (COPD) patients to breathe.

BRETARIS GENUAIR is indicated to help open the airways and relieve symptoms of COPD, a serious, long-term lung disease characterised by breathing difficulties. Regular use of BRETARIS GENUAIR can help you when you have ongoing shortness of breath related to your disease and will help you to minimise the effects of the disease on your everyday life.

BRETARIS GENUAIR is indicated for maintenance treatment of your COPD; it should not be used to treat a sudden attack of breathlessness or wheezing. If your COPD symptoms (breathlessness, wheezing, cough) do not improve or get worse you should contact your doctor for advice as soon as possible.

Ask your doctor if you have any questions about why BRETARIS GENUAIR has been prescribed for you.

This medicine is only available with a doctor's prescription.

It is not addictive.

Before you use BRETARIS GENUAIR

When you must not use it

Do not use BRETARIS GENUAIR if you have an allergy to:

  • aclidinium bromide or any of the other ingredients of this medicine listed at the end of this leaflet
  • atropine or related bronchodilator medicines, for example ipratropium, tiotropium or oxitropium.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

Do not use this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. In that case, return it to your pharmacist.

Before you start to use it

Tell your doctor if you have any of the following medical conditions:

  • if you have asthma
  • if you have had heart problems recently
  • if you see halos around lights and coloured images, have eye pain or discomfort or temporary blurring of vision (narrow angle glaucoma)
  • if you have an enlarged prostate, problems passing urine, or a blockage in your bladder
  • if you have rare hereditary galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.

Your doctor may want to take special precautions if you have any of the above conditions.

BRETARIS GENUAIR may cause dryness in the mouth, which may cause tooth decay after using your medicine for a long time. Therefore, please remember to pay attention to oral hygiene.

Tell your doctor if you are pregnant, intend to become pregnant or are breastfeeding. BRETARIS GENUAIR is not recommended for use during pregnancy or while breastfeeding. If it is necessary for you to use this medicine during pregnancy or while breastfeeding, your doctor will discuss with you the benefits and risks involved.

Children and adolescents

BRETARIS GENUAIR is not for use in children or adolescents below 18 years of age.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and BRETARIS GENUAIR may interfere with each other. These include other medicines used to treat breathing difficulties, such as tiotropium, ipratropium or oxitropium (called anticholinergics).

You may need to take different amounts of your medicines or you may need to take different medicines. Your doctor and pharmacist have more information.

If you have not told your doctor about any of these things, tell him/ her before you start using BRETARIS GENUAIR.

How to use BRETARIS GENUAIR

Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in the leaflet.

If you do not understand the instructions, ask your doctor or pharmacist for help.

How much to use

The recommended dose is one inhalation twice a day in the morning and night.

The effects of BRETARIS GENUAIR last for 12 hours; therefore, you should try to use your BRETARIS GENUAIR inhaler at the same time every morning and at night. This ensures that there is always enough medicine in your body to help you breathe more easily throughout the day and night. It will also help you to remember to use it.

How to use

See instructions at the end of this leaflet or refer to booklet contained within the carton for instructions on how to use the BRETARIS GENUAIR inhaler.

If you are not sure of how to use BRETARIS GENUAIR, ask your doctor or pharmacist.

How long to use

Continue to use this medicine for as long as your doctor tells you to.

If it helps your breathing problems, your doctor may want you to keep using it for a long time.

This medicine helps to control your condition but it does not cure it.

If you want to stop treatment, first talk to your doctor, as your symptoms may worsen.

If you forget to use it

If you forget to have a dose of BRETARIS, inhale the dose as soon as you remember. However, if it is nearly time for your next dose, skip the missed dose.

Do not take a double dose to make up for the one that you missed. This may increase the chance of you getting an unwanted side effect.

If you have trouble remembering when to use your medicine, ask your pharmacist for some hints.

If you use too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have used too much BRETARIS. Do this even if there are no signs of discomfort or poisoning.

While you are using BRETARIS GENUAIR

Things you must do

Use this medicine exactly as your doctor has prescribed. Try not to miss any doses and use it even if you feel well.

If you do not follow your doctor's instructions, you may not get relief from your breathing problems or you may have unwanted side effects.

If you find that the usual dose of BRETARIS is not giving as much relief as before, or does not last as long as usual, contact your doctor so that your condition can be checked. This is important to ensure your COPD is controlled properly.

If you become pregnant while using this medicine, tell your doctor. Your doctor can discuss with you the risks of using it while you are pregnant.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are using BRETARIS GENUAIR.

Tell any other doctors, dentists, and pharmacists who treat you that you are using this medicine.

Things you must not do

Do not exceed the recommended daily dose – it will not help you to do this.

Do not take any other medicines for your breathing problems without checking with your doctor.

Do not give this medicine to anyone else, even if their condition seems similar to yours.

Do not use it to treat any other complaints unless your doctor tells you to.

Things to be careful of

Be careful driving, operating machinery or doing jobs that require you to be alert until you know how BRETARIS GENUAIR affects you. This medicine may cause headache, dizziness or blurred vision. If you are affected by either of these side effects do not drive or use machinery until the headache has cleared and your vision has returned to normal.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using BRETARIS GENUAIR.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by these lists of possible side effects. You may not experience any of them. Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • headache
  • inflammation of the sinuses (sinusitis)
  • runny nose or sneezing (rhinitis)
  • common cold or flu symptoms
  • cough
  • diarrhoea, vomiting, nausea or abdominal discomfort
  • dry mouth
  • changes in voice
  • fungal infection in the mouth (candidiasis)
  • dizziness
  • toothache or infection in the tissues at the base of a tooth (tooth abscess)
  • inflammation of the mouth (stomatitis)
  • blurred vision
  • fall
  • heart failure, diabetes, arthritis
  • itchy rash.

Tell your doctor as soon as possible if you notice any of the following:

  • palpitations (feeling your heartbeat is unusually fast or irregular)
  • difficulty passing urine (urinary retention).

Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if any of the following happen:

  • you develop signs of an allergic reaction such as swelling of the face, lips, tongue, throat or other part of the body; severe dizziness or fainting, faster heart rate, redness, itching or rash on the skin
  • if you get tightness of the chest, coughing, wheezing or breathlessness immediately after using the medicine. These may be signs of a condition called bronchospasm.

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell.

After using BRETARIS GENUAIR

Storage

Keep the BRETARIS GENUAIR inhaler protected in the sealed pouch until you need to start using it.

The inhaler must be used within 90 days of opening the pouch.

Keep your inhaler in a cool dry place where the temperature stays below 30°C.

Do not store BRETARIS GENUAIR or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Disposal

If your doctor tells you to stop using the inhaler or the expiry date has passed, ask your pharmacist how to dispose of it properly.

Instructions for Use

Getting Started

Before using the BRETARIS GENUAIR inhaler, please read the full instructions.

You should become familiar with the parts of your inhaler (see image 1).

Before Use

  • Before first use, tear the sealed pouch along the notch and remove the inhaler.
  • Do not press the green button until you are ready to take a dose.
  • When you are about to take your dose of medicine, remove the protective cap by LIGHTLY SQUEEZING THE ARROWS marked on each side and pulling outwards (see image 2).

Step 1: Activate your inhaler

1.1 Look to see that nothing is blocking the mouthpiece (see image 3).

1.2 Look at the coloured control window and it should be red (see image 3).

1.3 Hold the inhaler horizontally with the mouthpiece towards you and the green button facing straight up (see image 4).

Make sure the green button is on top. DO NOT TILT.

1.4 Press the green button all the way down to load your dose (see image 5). When you press the button all the way down, the control window changes from red to green.

1.5 Release the green button (see image 6).

Make sure you release the green button so the inhaler can work correctly.

Stop and Check: Make sure your dose is ready for inhalation

1.6 Make sure the coloured control window has changed to GREEN (see image 7).

  • The green control window confirms that your medicine is ready for inhalation.

IF THE COLOURED CONTROL WINDOW STAYS RED AFTER PRESSING THE GREEN BUTTON ALL THE WAY DOWN, GO BACK TO 'STEP 1 ACTIVATE YOUR INHALER' AND REPEAT STEPS 1.1 TO 1.6.

Step 2: Inhale your dose

Read steps 2.1 to 2.7 fully before use. DO NOT HOLD THE GREEN BUTTON DOWN WHILE INHALING. Do not tilt.

2.1 Before bringing the inhaler to your mouth, breathe out completely away from the mouthpiece. Do not breathe out into the mouthpiece of the inhaler.

2.2 Hold your head upright and close your lips tightly around the mouthpiece of the inhaler.

2.3 Breathe in STRONGLY and DEEPLY through your mouth (see image 8). This strong, deep breath pulls the medicine through the inhaler into your lungs.

While you breathe in you will hear a “CLICK” which signals that you are inhaling correctly. Keep breathing in for as long as possible even after you have heard the “CLICK” to be sure you get the full dose.

ATTENTION: DO NOT HOLD THE GREEN BUTTON DOWN WHILE YOU ARE INHALING. DO NOT TILT.

2.4 Remove the inhaler from your mouth.

2.5 Hold your breath for as long as is comfortable.

2.6 Breathe out slowly through your nose, away from the mouthpiece.

Some patients may experience a grainy sensation in their mouth, or a slightly sweet or bitter taste when inhaling the medicine. Do not take an extra dose if you do not taste or feel anything after inhaling.

Stop and Check: Make sure you have inhaled correctly

2.7 Make sure the control window is now RED (see image 9). This confirms that you have inhaled your full dose correctly.

IF THE COLOURED CONTROL WINDOW IS STILL GREEN, THIS MEANS YOU HAVE NOT INHALED YOUR FULL DOSE CORRECTLY. GO BACK TO 'STEP 2 INHALE YOUR DOSE' AND REPEAT STEPS 2.1 TO 2.7.

  • If the control window still does not change to RED, you may have forgotten to release the green button before inhaling or may not have inhaled correctly. If that happens, try again.

Make sure you have RELEASED the green button and take a STRONG DEEP breath in through the mouthpiece.

Note: If you are unable to inhale correctly after several attempts, consult your doctor.

  • Once the control window has turned red, replace the protective cap by pressing it back onto the mouthpiece (see image 10). This will prevent moisture from getting inside the mouthpiece of your inhaler.

Additional Information

What should you do if you accidentally prepared a dose?
Store your inhaler with the protective cap in place until it is time to inhale your dose, then remove the cap and start at Step 1.6.

How should you clean the inhaler?
You DO NOT NEED to clean your inhaler. However, if you wish to clean it you should do so by wiping the outside of the mouthpiece with a dry tissue or paper towel.

NEVER use water to clean the inhaler, as this may damage your medicine.

How does the dose indicator work?

  • The inhaler is equipped with a dose indicator to show you approximately how many doses are left in the inhaler.
  • On first use, every inhaler contains at least 60 doses, or at least 30 doses, depending on the pack size.
  • Each time you load a dose by pressing the green button all the way down, the dose indicator moves down slowly displaying intervals of 10 (60, 50, 40, 30, 20, 10, 0) (see image 11).

When should you get a new inhaler?

You should get a new inhaler:

  • When a RED STRIPED BAND appears in the dose indicator (see image 11); this means you are nearing your last dose, or
  • If your inhaler appears to be damaged or if you lose the cap, or
  • If your inhaler is empty (see 'How do you know that your inhaler is empty?').

How do you know that your inhaler is empty?

  • When 0 (zero) appears in the middle of the dose indicator, you should continue using any doses remaining in the inhaler.
  • When the last dose has been prepared for inhalation, the green button will not return to its full upper position, but will be locked in a middle position (see image 12). Even though the green button is locked, your last dose may still be inhaled. After that, the inhaler cannot be used again and you should start using a new BRETARIS GENUAIR inhaler.

4 Clinical Particulars

4.1 Therapeutic Indications

Bretaris Genuair is indicated as a long-term maintenance bronchodilator treatment to relieve symptoms in adult patients with chronic obstructive pulmonary disease (COPD).

4.2 Dose and Method of Administration

Use in adults.

The recommended dose is one inhalation of Bretaris Genuair twice daily, once in the morning and once at night.

Method of administration.

Bretaris Genuair must be administered only by the oral inhalation route. Bretaris Genuair should be administered in the morning and at night and should be taken 12 hours apart. If a dose is missed the next dose should be taken as soon as possible. However, if it is nearly time for the next dose, the missed dose should be skipped.

Use in children.

Bretaris Genuair should not be used in patients under 18 years of age.

Use in the elderly.

No dose adjustments are required for elderly patients (see Section 5 Pharmacological Properties).

Use in patients with impaired renal function.

No dose adjustments are required for patients with renal impairment (see Section 5 Pharmacological Properties).

Use in patients with impaired hepatic function.

No dose adjustments are required for patients with hepatic impairment (see Section 5 Pharmacological Properties).

4.3 Contraindications

Bretaris Genuair is contraindicated in patients with a history of hypersensitivity to atropine or its derivatives, including ipratropium, oxitropium or tiotropium or to any other component of this product (see Section 2 Qualitative and Quantitative Composition).

4.4 Special Warnings and Precautions for Use

Asthma.

Bretaris Genuair should not be used for the treatment of asthma; clinical trials of aclidinium bromide in asthma have not been conducted.

Paradoxical bronchospasm.

As with other inhalation therapies, administration of Bretaris Genuair may cause paradoxical bronchospasm. If paradoxical bronchospasm occurs, treatment with Bretaris Genuair should be discontinued immediately and alternative therapy instituted.

Deterioration of disease.

Aclidinium bromide is a maintenance bronchodilator and should not be used for the relief of acute episodes of bronchospasm, i.e. as a rescue therapy. In the event of a change in COPD intensity while the patient is being treated with Bretaris Genuair so that the patient considers additional rescue medication is required, medical advice and a re-evaluation of the patient and the patient's treatment regimen should be conducted. An increase in the daily dose of Bretaris Genuair beyond the maximum dose is not appropriate.

Cardiovascular effects.

Bretaris Genuair should be used with caution in patients with a myocardial infarction during the previous 6 months, unstable angina, newly diagnosed arrhythmia within the previous 3 months, or hospitalisation within the previous 12 months for heart failure functional classes III and IV as per the "New York Heart Association". Experience in patients with cardiovascular comorbidities in clinical trials is limited (see Section 5.1 Pharmacodynamic Properties). These conditions may be affected by the anticholinergic mechanism of action.

Anticholinergic activity.

Dry mouth, which has been observed with anticholinergic treatment, may in the long term be associated with dental caries.
Consistent with its anticholinergic activity, Bretaris Genuair should be used with caution in patients with symptomatic prostatic hyperplasia or bladder neck obstruction or with narrow angle glaucoma (even though direct contact of the product with the eyes is very unlikely).

Excipients.

Bretaris Genuair contains lactose. Therefore, patients with rare hereditary problems of galactose intolerance, severe lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Use in the elderly.

No dosage adjustment is required for elderly patients.

Paediatric use.

Bretaris Genuair should not be used in patients under 18 years of age.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

The coadministration of Bretaris Genuair with inhaled anticholinergic (e.g. tiotropium bromide, glycopyrronium, aclidinium) containing medicinal products has not been studied and is therefore, like for other anticholinergics, not recommended.
In vitro studies have shown that aclidinium bromide or the metabolites of aclidinium bromide at the therapeutic dose are not expected to cause interactions with P-glycoprotein substrate drugs or drugs metabolised by cytochrome P450 (CYP450) enzymes and esterases (see Section 5 Pharmacological Properties).

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

Studies in rats have shown slight reductions in male and female fertility only at dose levels much higher than the maximum human exposure to aclidinium bromide. Fertility was unaffected in rats with inhalational administration at doses up to 0.86 mg/kg/day (females) or 1.84 mg/kg/day (males), yielding plasma AUC values for aclidinium bromide > 62 times higher than in patients at the recommended human dose. It is considered unlikely that Bretaris Genuair administered at the recommended dose will affect fertility in humans.
(Category B3)
There are no data available on the use of aclidinium bromide in pregnant women. Aclidinium bromide and/or its metabolites were shown to cross the placenta in rats. Developmental toxicity studies in animals revealed delayed ossification of fetuses in rats treated at ≥ 0.78 mg/kg/day by inhalation (yielding 24 times the plasma AUC for aclidinium bromide in patients at the recommended dose) and decreased fetal weight in rabbits with oral administration at ≥ 300 mg/kg/day; these doses were maternotoxic. Embryofetal development was unaffected in the rabbit at inhalational doses ≤ 3.58 mg/kg/day (yielding 11 times the plasma AUC in patients). Aclidinium bromide was not teratogenic in either animal species.
Because there are no adequate and well controlled studies in pregnant women, Bretaris Genuair should only be used during pregnancy if the expected benefits justify the potential risks to the fetus.
It is unknown whether aclidinium bromide and/or its metabolites are excreted in human milk. Excretion of small amounts of aclidinium bromide and/or metabolites into milk has been shown in the rat, with postnatal body weight gain suppressed in the offspring of animals given the drug during pregnancy and lactation at ≥ 0.20 mg/kg/day by inhalation (there was no effect at 0.018 mg/kg/day, estimated to yield around 7 times the clinical plasma AUC). A decision must be made whether to discontinue breastfeeding or to discontinue therapy with Bretaris Genuair taking into account the benefit of breastfeeding for the child and the benefit of long-term Bretaris Genuair therapy to the woman.

4.7 Effects on Ability to Drive and Use Machines

Aclidinium bromide may have minor influence on the ability to drive and use machines. The occurrence of blurred vision, dizziness or headache following the administration of aclidinium bromide may influence the ability to drive or to use machinery.

4.8 Adverse Effects (Undesirable Effects)

The safety data below reflect exposure of 636 patients to Bretaris Genuair 322 microgram twice daily in three placebo controlled trials. Two of these trials were 12 weeks and one was 24 weeks in duration. In these trials, 367 and 269 COPD patients were exposed to Bretaris Genuair 322 microgram twice daily for 12 weeks and 24 weeks, respectively. In this population, 5.1% of patients who received placebo and 4.6% of patients who received Bretaris Genuair 322 microgram discontinued the studies prematurely due to adverse events.
A placebo-controlled trial in 1791 patients with moderate to very severe COPD treated with Bretaris Genuair up to 36 months identified a similar pattern of adverse reactions.
Table 1 summarises the adverse reactions from the three placebo controlled clinical trials that occurred with a frequency of ≥ 1% in the Bretaris Genuair groups.
Other adverse reactions that occurred in the Bretaris Genuair groups at a frequency of < 1% where rates exceeded that in the placebo group include:

Cardiac disorders.

Cardiac failure.

Gastrointestinal disorders.

Abdominal discomfort, dry mouth.

Infections and infestations.

Candidiasis, tooth abscess.

Metabolism and nutrition disorders.

Diabetes mellitus.

Musculoskeletal and connective tissue disorders.

Osteoarthritis.

Respiratory, thoracic and mediastinal disorders.

Dysphonia.

Eye disorder.

Blurred vision.

Renal and urinary disorders.

Urinary retention.

Long-term safety trials.

Bretaris Genuair was studied in three long-term safety trials, two double blind and one open label, ranging from 40 to 52 weeks in patients with moderate to severe COPD. In these trials, 1005 patients were treated with Bretaris Genuair at the recommended dose of 322 microgram twice daily. The adverse events reported in the long-term safety trials were similar to those occurring in the placebo controlled trials of 3 to 6 months.

Post-marketing experience.

Table 2 includes post-marketing events reported in patients treated with aclidinium bromide. Adverse drug reactions are listed according to system organ classes in MedDRA and the frequency established in the EU SmPC.

Reporting of suspected adverse reactions.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at http://www.tga.gov.au/reporting-problems.

4.9 Overdose

For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).
High doses of aclidinium bromide may lead to anticholinergic signs and symptoms.
However, single inhaled doses up to 6000 microgram aclidinium bromide have been administered to healthy subjects without systemic anticholinergic adverse effects. Additionally, no clinically relevant adverse effects were observed following 7 day twice daily dosing of up to 800 microgram aclidinium bromide in healthy subjects.
Acute intoxication by inadvertent medicinal product ingestion of aclidinium bromide is unlikely due to its low oral bioavailability and the breath actuated dosing mechanism of the Genuair inhaler.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Aclidinium bromide is a competitive muscarinic receptor antagonist (also known as an anticholinergic), with subnanomolar affinity for all five human muscarinic receptor subtypes (M1-M5) and a longer residence time at the M3 receptors than the M2 receptors. M3 receptors mediate contraction of airway smooth muscle. Inhaled aclidinium bromide acts locally in the lungs to antagonise M3 receptors of airway smooth muscle and induce bronchodilation. Nonclinical in vitro and in vivo studies showed rapid, dose dependent and long lasting inhibition by aclidinium bromide of acetylcholine induced bronchoconstriction. Aclidinium bromide is quickly broken down in plasma, the level of systemic anticholinergic side effects is therefore low.

Effects on cardiac electrophysiology.

No effects on QT interval (corrected using either the Fridericia or Bazett method or individually corrected) were observed when aclidinium bromide (200 microgram or 800 microgram) was administered once daily for 3 days to healthy subjects in a thorough QT study.
In addition, no clinically significant effects of Bretaris Genuair on cardiac rhythm were observed on 24 hour Holter monitoring after 3 months treatment of 336 patients (of whom 164 received Bretaris Genuair 322 microgram twice daily).

Clinical trials.

The Bretaris Genuair phase III clinical development programme included 269 patients treated with Bretaris Genuair 322 microgram twice daily in one 6 month randomised, placebo controlled study and 190 patients treated with Bretaris Genuair 322 microgram twice daily in one 3 month randomised, placebo controlled study. Efficacy was assessed by measures of lung function and symptomatic outcomes such as breathlessness, disease specific health status, use of rescue medication and occurrence of exacerbations.

Lung function.

Clinical efficacy studies showed that Bretaris Genuair provided clinically meaningful improvements in lung function (as measured by the forced expiratory volume in 1 second [FEV1]) over 12 hours following morning and evening administration, which were evident within 30 minutes of the first dose (increases from baseline of 124-133 mL). Maximal bronchodilation was achieved within 1-3 hours after dosing with mean peak improvements in FEV1 relative to baseline of 227-268 mL at steady-state.
In the 6 month study, patients receiving Bretaris Genuair 322 microgram twice daily experienced a clinically meaningful improvement in their lung function (as measured by FEV1). Maximal bronchodilatory effects were evident from day one and were maintained over the 6 month treatment period. After 6 months treatment, the mean improvement in morning predose (trough) FEV1 compared to placebo was 128 mL (95% CI = 85-170; p < 0.0001).
Similar observations were made with Bretaris Genuair in the 3 month study.
In the long-term safety studies, Bretaris Genuair was associated with bronchodilatory efficacy when administered over a 1 year treatment period.

Disease specific health status and symptomatic benefits.

Bretaris Genuair provided clinically meaningful improvements in breathlessness (assessed using the Transition Dyspnoea Index [TDI]) and disease specific health status (assessed using the St George's Respiratory Questionnaire [SGRQ]). Table 3 shows symptom relief obtained after 6 months treatment with Bretaris Genuair.
Patients treated with Bretaris Genuair required less rescue medication than patients treated with placebo (a reduction of 0.95 puffs per day at 6 months [p = 0.005]). Bretaris Genuair also improved daily symptoms of COPD (dyspnoea, cough and sputum production) and night time and early morning symptoms.

Long term safety and efficacy trial up to 3 years.

The effect of aclidinium bromide on the occurrence of major adverse cardiovascular events (MACE) was assessed in a randomised, double-blind, placebo-controlled, parallel-group study in 3630 adult patients between 40 and 91 years of age with moderate to very severe COPD treated for up to 36 months. 58.7% were male and 90.7% were Caucasian, with a mean post-bronchodilator FEV1 of 47.9% of predicted value and a mean CAT (COPD Assessment Test) of 20.7. All patients had a history of cardiovascular or cerebrovascular disease and/or significant cardiovascular risk factors. 59.8% of patients had at least one COPD exacerbation within the past 12 months from the screening visit. Approximately 48% of enrolled patients had a prior history of at least 1 documented previous cardiovascular event; cerebrovascular disease (13.1%), coronary artery disease (35.4%), peripheral vascular disease or history of claudication (13.6%).
The study had an event-driven design and was terminated once sufficient MACE events for the primary safety analysis were observed. Patients discontinued treatment if they experienced a MACE event and entered into the post-treatment follow-up period during the study. 70.7% of patients completed the study per investigator assessment. The median time on-treatment in the Bretaris Genuair and placebo groups was 1.1 and 1 year, respectively. The median time on-study in the Bretaris Genuair and placebo groups was approximately 1.4 and 1.3 years, respectively.
The primary safety endpoint was the time to first occurrence of MACE, defined as any of the following adjudicated events: cardiovascular death, non-fatal myocardial infarction (MI), or non-fatal ischemic stroke. The frequency of patients with at least one MACE was 3.85% vs. 4.23% patients in the Bretaris Genuair and placebo groups, respectively. Bretaris Genuair did not increase the MACE risk in patients with COPD compared to placebo when added to current background therapy (hazard ratio (HR) 0.89; 95% CI: 0.64, 1.23). The upper bound of the confidence interval excluded a pre-defined risk margin of 1.8.
The Kaplan-Meier-based cumulative event probability is presented in Figure 1.
The rate of moderate or severe COPD exacerbations per patient per year during the first year of treatment was evaluated as the primary efficacy endpoint in the study. Moderate to severe exacerbations were defined as worsening of COPD symptoms (e.g. dyspnoea, cough, sputum) for at least 2 consecutive days that required a treatment with antibiotics and/or systemic corticosteroids or resulted in hospitalisation or led to death. Patients treated with Bretaris Genuair 400 microgram BID showed a statistically significant reduction of 22% compared to placebo (rate ratio [RR] 0.78; 95% CI 0.68 to 0.89; p < 0.001). In addition, Bretaris Genuair showed a statistically significant reduction of 35% in the rate of hospitalisation due to COPD exacerbations while on-treatment during the first year compared with placebo (RR 0.65; 95% CI 0.48 to 0.89; p = 0.006).
The Kaplan-Meier curves indicate that the time to first moderate or severe COPD exacerbation was delayed in the aclidinium 400 microgram group while on treatment compared to the placebo group (see Figure 2). Patients in the aclidinium bromide 400 microgram group had a 18% relative reduction of the risk of an exacerbation (HR 0.82; 95% CI [0.73, 0.92], p < 0.001).

Exercise tolerance.

In a 3 week crossover, randomised, placebo controlled clinical study Bretaris Genuair was associated with a statistically significant improvement in exercise endurance time in comparison to placebo of 58 seconds (95% CI = 9-108; p = 0.021; pretreatment value: 486 seconds). Bretaris Genuair statistically significantly reduced lung hyperinflation at rest (functional residual capacity [FRC] = 0.197 L [95% CI = 0.321, 0.072; p = 0.002]); residual volume [RV] = 0.238 L [95% CI = 0.396, 0.079; p = 0.004] and also improved trough inspiratory capacity (by 0.078 L; 95% CI = 0.01, 0.145; p = 0.025) and reduced dyspnoea during exercise (Borg scale) (by 0.63 Borg units; 95% CI = 1.11, 0.14; p = 0.012).
The efficacy and safety of aclidinium bromide (400 microgram BID) beyond 1 year has not been evaluated.

5.2 Pharmacokinetic Properties

Absorption.

Aclidinium bromide is rapidly absorbed from the lung, achieving maximum plasma concentrations within 5 minutes of inhalation in healthy subjects, and normally within the first 15 minutes in chronic obstructive pulmonary disease (COPD) patients. The fraction of the inhaled dose that reaches the systemic circulation as unchanged aclidinium is very low at less than 5%.
Steady state peak plasma concentrations achieved after dry powder inhalation by COPD patients of 400 microgram aclidinium bromide were approximately 224 (± 94) picogram/mL. Steady-state plasma levels were attained within seven days of twice daily dosing.

Distribution.

Whole lung deposition of inhaled aclidinium bromide via the Genuair inhaler averaged approximately 30% of the metered dose.
The plasma protein binding of aclidinium bromide determined in vitro most likely corresponded to the protein binding of the metabolites due to the rapid hydrolysis of aclidinium bromide in plasma; human plasma protein binding was 87% for the carboxylic acid metabolite and 15% for the alcohol metabolite. The main plasma protein that binds aclidinium bromide is albumin.

Metabolism.

Aclidinium bromide is rapidly and extensively hydrolysed to its pharmacologically inactive alcohol and carboxylic acid derivatives. The hydrolysis occurs both chemically (nonenzymatically) and enzymatically by esterases (principally in plasma), with butyrylcholinesterase being the main human esterase involved in the hydrolysis. Plasma levels of the acid metabolite are approximately 100-fold greater than those of the alcohol metabolite and the unchanged active substance following inhalation.
The low absolute bioavailability of inhaled aclidinium bromide (< 5%) is because aclidinium bromide undergoes extensive systemic and presystemic hydrolysis whether deposited in the lung or swallowed.
Biotransformation via CYP450 enzymes plays a minor role in the total metabolic clearance of aclidinium bromide.
In vitro studies have shown that aclidinium bromide and its major metabolites do not inhibit human CYPs 1A2, 2A6, 2B6, 2B8, 2C9, 2C19, 2D6, 2E1, 3A4/5 or 4A9/11, do not induce CYPs 1A2, 2B6, 2C8, 2C9, 2C19 or 3A4/5, and do not inhibit esterases (carboxylesterase, acetylcholinesterase and butyrylcholinesterase) at therapeutic concentrations.
In vitro studies have shown that neither aclidinium bromide nor the main metabolites of aclidinium bromide are inhibitors of P-glycoprotein. The same studies have also demonstrated that aclidinium bromide and its acid metabolite are not substrates of P-glycoprotein, however its alcohol metabolite is a potentially weak substrate.

Elimination.

The effective half-life of aclidinium was approximately 10 hours following inhalation of twice daily 400 microgram doses in COPD patients.
Following intravenous administration of 400 microgram radiolabelled aclidinium bromide to healthy subjects, approximately 1% of the dose was excreted as unchanged aclidinium bromide in the urine. Up to 65% of the dose was eliminated as metabolites in the urine and up to 33% as metabolites in the faeces.
Following inhalation of 200 microgram and 400 microgram of aclidinium bromide by healthy subjects or COPD patients, the urinary excretion of unchanged aclidinium was very low at about 0.1% of the administered dose, indicating that renal clearance plays a minor role in the total aclidinium clearance from plasma.

Linearity/ nonlinearity.

Aclidinium bromide demonstrated kinetic linearity and a time independent pharmacokinetic behaviour in the therapeutic range.

Pharmacokinetic/ pharmacodynamic relationship.

Aclidinium bromide acts locally in the lungs and is quickly broken down in plasma. Consequently, there is no direct relationship between pharmacokinetics and pharmacodynamics.

Pharmacokinetics in special patient groups.

Elderly patients.

The pharmacokinetic properties of aclidinium bromide in patients with moderate to severe COPD appear to be similar in patients aged 40-59 years and in patients aged ≥ 70 years. Therefore, no dose adjustment is required for elderly COPD patients.

Patients with renal impairment.

No significant pharmacokinetic differences were observed between subjects with normal renal function and subjects with renal impairment. Therefore, no dose adjustment and no additional monitoring are required for renally impaired COPD patients.

Patients with hepatic impairment.

No studies have been performed on hepatically impaired patients. As aclidinium bromide is metabolised mainly by chemical and enzymatic cleavage in the plasma, hepatic dysfunction is very unlikely to alter its systemic exposure. No dose adjustment is required for hepatically impaired COPD patients.

5.3 Preclinical Safety Data

Genotoxicity.

Aclidinium bromide returned equivocal results in assays for bacterial mutagenicity and in the mouse lymphoma tk assay in vitro. Aclidinium bromide, at high levels of systemic exposure, was devoid of genotoxicity in vivo in the mouse bone marrow micronucleus test and in the unscheduled DNA synthesis (UDS) assay in rat liver. Aclidinium bromide is not considered to pose a genotoxic hazard to patients.

Carcinogenicity.

No treatment related neoplastic lesions were noted in the carcinogenicity studies of 2 years duration in mice and rats, involving inhalational administration. The highest dose levels employed in the respective species (2.45 mg/kg/day in mice and 0.20 mg/kg/day in rats) yield approximately 50 and 21 times the plasma AUC in patients at the recommended dose and approximately 120 and 11 times the local dose in the lung.
