Summary
The purpose of this study is to estimate the relative potency for bronchoprotective effect
of formoterol Novolizer 12 µg (test) compared to formoterol Aerolizer 12 µg (reference).
Clinical Details
Official title: Relative Potency of Formoterol Novolizer® 12 µg Compared to Formoterol Aerolizer® 12 µg in Patients With Stable Asthma Using Bronchoprovocation With Methacholine as a Bioassay Randomized, Double-blind, Four-period, Four-sequence Cross-over Trial
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: PC20 = Provocation Concentration of Methacholine That Cause a 20% Decrease in Forced Expiratory Volume in the First Second (FEV1)
Eligibility
Minimum age: 18 Years.
Maximum age: 60 Years.
Gender(s): Both.
Criteria:
Inclusion Criteria:
1. Male or female patients aged from 18 to 60 years (inclusive).
2. Patients with asthma indicated by
- history of asthma symptoms and
- airway hyperresponsiveness to methacholine with a provocation concentration of
methacholine that cause a 20% decrease in FEV1 (PC20) ≤8 mg/ml at Visit 1.
3. Patients with stable asthma condition with baseline forced expiratory volume in the
first second (FEV1) ≥70% predicted at first visit.
4. The PC20 methacholine should increase at least 4-fold after inhaling 24 μg of
formoterol Aerolizer (2 applications of 12 μg) at Visit 2.
5. Able to be taught correct inhalation technique for both devices at screening.
Exclusion Criteria:
1. Known hypersensitivity to formoterol, lactose, or methacholine.
2. History of life-threatening asthma in the last three years.
3. Major malignancies including pheochromocytoma within the last 5 years. Exception will
be considered where malignancies have been resolved as judged by investigator.
4. Pregnancy, breast-feeding, planned pregnancy during the study, or women of
child-bearing potential not using adequate contraception. These methods include total
abstinence (no sexual intercourse), oral contraceptives, an intrauterine device
(IUD), an etonogestrel implant (Implanon), or medroxyprogesterone acetate injections
(Depo-Provera shots). If one of these cannot be used, using contraceptive foam and a
condom are recommended.
Lack of suitability for the study:
5. Screening visit 2 has to be postponed repeatedly.
6. Evidence of respiratory tract infection within 4 weeks before the study (screening
visit 1).
7. Seasonal or episodic exposure to an allergen or occupational chemical sensitizer
which are likely to vary in symptom presentation and severity during the course of
the study (e. g. ragweed sensitive patients in Iowa during Aug-Oct). This does not
apply to patients who can be well controlled on therapy.
8. History of non-reversible pulmonary disease; chronic obstructive pulmonary disease
(COPD), cystic fibrosis, bronchiectasis, or pulmonary fibrosis.
9. History of severe cardiovascular, renal, neurologic, liver or endocrine dysfunction
(patients with well-controlled hypertension, hypercholesterolemia, thyroid disease or
diabetes may be included if medication for these diseases does not affect
methacholine challenge or formoterol metabolism).
10. History of hemophilia or coagulation disease.
11. Electrocardiogram (ECG) abnormalities of clinical relevance, in particular abnormal
prolongation of QT-interval (QTc according to Bazett in women ≥450 msec, in men ≥430
msec).
12. Potassium level below lower limit of laboratory normal range plus 0. 3 mmol/l as
safety margin.
13. Exacerbation of bronchial asthma requiring emergency department visit or
hospitalization during the last 3 months prior to this study.
14. Prior or concomitant treatment with systemic glucocorticosteroids during the last 3
months (a short course of oral corticosteroids for asthma is permissible if for <10
days and at least 30 days have passed).
15. Use of long-acting ß2-agonists in last 3 weeks before the first methacholine
challenge or during the study
16. Change in dosage of other controller therapy (inhaled glucocorticosteroids,
leukotriene modifier, slow-release theophylline) during the last 3 weeks before the
first methacholine challenge or during the study.
17. Use of short-acting ß2-agonists more than thrice a week in the previous month.
18. Inability to temporary withhold the following medications/substances before lung
function test:
- short-acting ß2-agonists and short-acting anticholinergics at least 6 hours,
- regular long-acting ß2-agonists at least 3 weeks,
- long-acting anticholinergics at least 36 hours,
- inhaled glucocorticosteroids at least 2 hours
- Disodium cromoglycate (DSCG) at least 24 hours,
- slow release theophylline at least 48 hours,
- rapid release theophylline at least 24 hours,
- caffeine at least 4 hours
19. Patients with aspirin induced bronchospasm.
20. Any treatment with ß2-antagonists (including eye drops).
21. Non-cooperative patients, inability to perform outcome measurement correctly.
22. Inability to measure PC20 methacholine after 24 μg of formoterol Aerolizer (PC20 >128
mg/ml).
23. Current smokers or regular smokers during last 12 months or more than 10 pack-year
history.
24. Drug or alcohol abuse which would interfere with the patient's proper completion of
the protocol assignment.
Administrative reasons:
25. Participation in another clinical study within 1 month prior to or during this study
26. Lack of ability or willingness to give informed consent.
27. Lack of willingness to have personal study related data collected, archived or
transmitted according to protocol.
28. Personnel involved in the planning or conduct of the study.
29. Anticipated non-availability for study visits/procedures.
