Study of Safety of CSJ117 in Participants With Moderate to Severe Uncontrolled Asthma

Asthma Clinical Trial

Official title: A 24-week, Multicenter, Randomized, Double-blind, Parallel-arm, Placebo-controlled Extension Study to Assess the Safety of CSJ117, When Added to Existing Standard of Care Asthma Therapy in Patients ≥18 Years of Age

Status Terminated

Clinical Trial Summary

The purpose of this study is to provide safety and tolerability, pharmacokinetics and immunogenicity data for multiple CSJ117 doses inhaled once daily compared with placebo, in adult asthma participants treated with medium or high dose ICS plus LABA alone or with additional asthma controllers (additional controllers allowed: LTRA, LAMA, Theophylline and its derivatives), who have completed the prior phase llb study CCSJ117A12201C (NCT04410523).

Clinical Trial Description

This is a 12/24-week Phase llb, multicenter, multi-national, double-blind, randomized, parallel-arm, placebo-controlled extension study to evaluate the safety and tolerability, pharmacokinetics and immunogenicity of 5 dose levels of CSJ117 in adult asthma participants treated with medium or high dose ICS plus LABA alone or with additional asthma controllers (allowed: LTRA, LAMA, theophylline or its derivatives), who have completed the prior core phase llb study CCSJ117A12201C (NCT04410523). The study will include the following three parts:

A Screening period of up to 3 days to assess eligibility.

A Treatment period of 12 or 24 weeks. There are two scenarios on when a participant can enroll into the extension study depending on when the study site is activated for the extension study CCSJ117A12201E1:

• A 24 week treatment period: Participants on each of the five treatment arms (CSJ117 0.5 to 8 mg) or placebo of the core study CCSJ117A12201C, who will enter the extension study after the last Treatment period visit (week 12) of the core study, will be randomized in a 1:1 ratio to continue on their previously assigned CSJ117 dose or placebo from CCSJ117A12201C for 24 weeks, or to first go through a 12-week "washout period" receiving placebo (for the blinding purpose) and then restart on their previously assigned CSJ117 dose or placebo from CCSJ117A12201C for 12 weeks.

• A 12 week treatment period: Participants on each of the five treatment arms (CSJ117 0.5 to 8 mg) or placebo of the core study CCSJ117A12201C, who will enter the extension study after the last Follow-up visit (week 24) of the core study, will restart on their previously assigned CSJ117 dose or placebo from CCSJ117A12201C for 12 weeks.

A Follow-up period of 12 weeks, study drug free, following the last dose of study drug. ;
