| NCT02566044 | Safety, Pharmacokinetics and Pharmacodynamics Study of Inhaled QBW276 in Patients With Cystic Fibrosis | PHASE1 | COMPLETED | 16 | — | — | Sep 27, 2017 | Apr 24, 2018 | Dec 30, 2020 | 4 | United States, Germany |
Adverse events were summarized by the number of patients having any adverse event overall and presented in the safety section. Study was prematurely terminated
Blood collection will be used to observe the maximum plasma concentration (Cmax) following administration of QBW276. Pharmacokinetic blood samples were collected at the time points. In Cohorts 1 and 2 this consisted of multiple samples through 6 hours after inhalation on Days 1 and 7 in Cohort 1 and Days 1 and 14 in Cohort 2 with predose samples on selected days. The Cmax, was determined using the actual recorded sampling times and noncompartmental methods. Since steady state was likely reached by Day 7, Cmax on Days 7 or 14 correspond to Cmax,ss
Blood collection will be used to observe the maximum plasma concentration (Tmax) following administration of QBW276. Pharmacokinetic blood samples were collected at the time points. In Cohorts 1 and 2 this consisted of multiple samples through 6 hours after inhalation on Days 1 and 7 in Cohort 1 and Days 1 and 14 in Cohort 2 with predose samples on selected days. The Tmax, was determined using the actual recorded sampling times and noncompartmental methods. Since steady state was likely reached by Day 7, Tmax on Days 7 or 14 correspond to Tmax,ss
Blood collection will be used to observe the maximum plasma concentration (AUCtau) following administration of QBW276. Pharmacokinetic blood samples were collected at the time points. In Cohorts 1 and 2 this consisted of multiple samples through 6 hours after inhalation on Days 1 and 7 in Cohort 1 and Days 1 and 14 in Cohort 2 with predose samples on selected days. The AUCtau, was determined using the actual recorded sampling times and noncompartmental methods. Since steady state was likely reached by Day 7, AUCtau on Days 7 or 14 correspond to AUClast,ss
The accumulation ratio (Racc) will be reported using blood samples taken on days 1 -7 in cohort 1 and days 1-14 in cohort 2. Accumulation ratio (Racc) for QBW276 and metabolites was not calculated by PK software for patients where BLOQ values were observed for all blood samples in their PK profile.

| CQBW276 | EXPERIMENTAL | Cohorts 1 and 2 will enroll 8 patients each (6:2 QBW276 and placebo, respectively). Cohort 1: dose is 3 mg bid (6 mg daily) QBW276 or placebo for 7 days. Cohort 2: dose and frequency will be confirmed after cohort 1 is complete. The duration is 14 days. Cohort 3: dose and frequency will be confirmed after cohort 2 is complete. The duration is approximately 4 months. Patients will be randomized to one of two treatment sequences: QBW276 in Period 1 and Placebo in Period 2 or Placebo in Period 1 and QBW276 in Period 2. Twenty four patients are required to complete cohort 3. |
