A Study of the Treatment-Sparing Effects of AEROVANT™ AER 001 Inhalation Powder in Asthma Patients, AEROTRIAL
Bu çalışma, mevcut tedaviyle tam kontrol altına alınamayan astım (asthma) hastalarında AEROVANT™ (AER 001) inhalasyon tozunun, standart tedavi ihtiyacını azaltıp azaltmadığını plaseboyla karşılaştırarak incelemiştir. Çalışmaya, orta-ağır düzeyde kalıcı astımı olan ve yüksek doz inhaler steroid ile uzun etkili bronkodilatör kullanan 18 yaş ve üzeri hastalar katılabilmiştir. Aerovance, Inc. tarafından yürütülen çalışma Faz 2 aşamasında yürütülmüş ve tamamlanmıştır.

Inclusion Criteria: 1. Male or female patient, ≥ 18 years of age with a documented clinical history of asthma, has been treated for asthma and, in the opinion of the Investigator, is not fully controlled on current asthma therapy. 2. Patient satisfies, or has satisfied in the past, the GINA definition of moderate persistent to severe persistent asthma. 3. Patient has been maintained on moderate-to-high doses of ICS and LABA in the form of combination therapy or as individual agents (equivalent to fluticasone ≥ 250 mcg bid and salmeterol ≥ 50 mcg bid for ≥ 4 weeks before Screening \[Visit 1\]). 4. Patient has experienced an asthma exacerbation at least once in the past 2 years (defined here as use of physician prescribed oral corticosteroids or asthma requiring treatment increase approximately 4 times the baseline dose of inhaled corticosteroids or hospitalization due to asthma). 5. Patient has a pre-bronchodilator FEV1 ≥ 50% but ≤ 95% of the predicted value at both Screening (Visit 1) and Visit 2. 6. Patient demonstrates ≥ 12% reversibility (and a ≥ 200 mL difference) from prebronchodilator FEV1 within 15 to 30 minutes of receiving up to 4 puffs of a short-acting beta-agonist at Screening (Visit 1) or has ≥ 10% reversibility from pre-bronchodilator FEV1 plus a documented reversibility of ≥ 12% within the previous 12 months (documented methacholine or histamine sensitivity (PC20) \<8mg/mL is also acceptable evidence or reversible airways disease). 7. Patient scores ≤ 20 on The Asthma Control Test™ at Screening (Visit 1) and Visit 2. 8. Female patient of childbearing potential or male patient and his female partner are practicing adequate and effective forms of contraception and agree to continue for the duration of the study. If female, must have a negative urine pregnancy test. 9. Patient has a pre-study medical history, physical examination, 12-Lead ECG, and safety laboratory test results within normal reference ranges or clinically acceptable to the Investigator. 10. Patient is a non-smoker for at least 6 months before Screening (Visit 1) and has a \< 10 pack/year history of smoking. 11. Patient is medically stable for at least 8 weeks before Randomization (Visit 2), and the Investigator does not consider study participation to place the patient at increased risk of AEs (with the exception of possible asthma exacerbations). 12. Patient is able and willing to give written informed consent. Exclusion Criteria: 1. Patient has a current diagnosis of respiratory disorder other than asthma (e.g., chronic bronchitis, bronchiectasis, emphysema, chronic obstructive pulmonary disease \[COPD\], etc). 2. Patient has received oral corticosteroid treatment within 8 weeks of Randomization (Visit 2)or patient has been intubated for ventilation in the past 5 years. 3. Patient has used any leukotriene antagonist within 1 week before Screening (Visit 1) or anti-IgE medications within 4 weeks of Screening (Visit 1). 4. Female patient is pregnant, breastfeeding, or not using an adequate method of contraception. 5. Patient has a clinically relevant medical history of very severs asthma that would preclude steroid reduction or sufficient compliance with the protocol. 6. Patient uses concomitant medications, including herbal, over-the-counter, or prescription medicines that, in the opinion of the Investigator, may affect the outcome of study endpoints and/or well-being of the patient. 7. Patient has a history of alcohol or substance abuse within 2 years of Screening (Visit 1). 8. Patient consumes more than 28 units (male) or 21 units (female) of alcohol a week (unit = 1 glass of wine = 1measure of spirits = ½ pint or 8 fluid ounces of beer). 9. Patient cannot communicate reliably with the Investigator or is unlikely to cooperate with the requirements of the study. 10. Patient has previously taken AEROVANT™ or another formulation of AER 001 (e.g., BAY 16-9996, pitrakinra). 11. Patient has participated in any clinical trial involving use of an investigational drug within 12 weeks of first dose of study drug.
