简要总结
This is a parallel, treatment, Phase 2, double-blind, 2 arm, 12-week Proof of Concept (PoC) study with 2 staggered cohorts (2 arms in each cohort) that is designed to assess the efficacy, safety, and tolerability of rilzabrutinib in adult participants (aged 18-70 years) with moderate-to-severe asthma who are not well controlled on ICS/LABA therapy. Study treatment includes investigational medicinal product (IMP) (rilzabrutinib or placebo) added-on to a background therapy of ICS/LABA (fluticasone/salmeterol [non-investigational medicinal product], standardized at screening). Background therapy of ICS/LABA will be withdrawn during the 12week randomized treatment period and resumed at the end of the IMP treatment period, as outlined below:
-
Screening period (4 weeks)
-
Randomized IMP treatment period (12 weeks ± 3 days)
-
Background therapy stabilization phase (4 weeks)
-
Background therapy withdrawal phase (4-5 weeks)
-
No background therapy phase (3-4 weeks)
-
Post IMP treatment safety follow-up period (4 weeks ± 3 days)
详细描述
The total study duration per participant is expected to be up to 20 weeks: up to 4 weeks screening, 12 weeks on-treatment double-blind period, and 4-week post-IMP treatment follow up.

- •Conditions that may predispose the participant to excessive bleeding
- •History of solid organ transplant.
- •A history of malignancy of any type within 5 years before Day 1, other than surgically excised non-melanoma skin cancers or in situ cervical cancer.
