Brief summary
The purpose of this study was to investigate the safety, tolerability and efficacy of VAY736 as potential therapy for the treatment of idiopathic pulmonary fibrosis (IPF).
Detailed description
This was an exploratory (non-confirmatory) randomized, patient-, investigator-, sponsor- blinded, placebo controlled study of VAY736 in IPF patients. This study investigated the safety and efficacy of 300 mg VAY736 administered subcutaneously (s.c.) every 4 weeks for 48 weeks. Participants were randomized in a 1:1 ratio on top of local standard of care (SOC), to receive VAY736 or placebo. Randomized subjects entered the treatment epoch (for up to 48 weeks), followed by two follow-up epochs: the PK/safety follow-up epoch and the PD/safety follow-up epoch. The PK/safety follow-up epoch lasted for 20 weeks. When the PK/safety follow-up epoch was completed, participants in the placebo arm were discharged from the study; but participants in the active arm (those who had received VAY736) continued into the PD/safety follow-up epoch. Participants in the PD/safety follow-up epoch were followed until B-cell recovery (in the peripheral blood), defined as: B cells \>=50/μL or B cells \>= 80% of baseline (whichever occurred first). If a participant had not recovered his/her B-cells after a period of 2 years from the last dose of VAY736, then this participant was discharged from the study.
