Clinical Trial Summary

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 Background therapy of ICS/LABA will be withdrawn during the 12week randomized treatment period and resumed at the end of the IMP treatment period, as outlined below: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)

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of participants with an LOAC event during the treatment period	Loss of Asthma Control (LOAC) event is defined as any of the following: A 30% or greater reduction from baseline in morning peak expiratory flow (PEF) on 2 consecutive days; =6 additional reliever puffs of salbutamol/albuterol or levosalbutamol/levalbuterol in a 24-hour period (compared to baseline) on 2 consecutive days; Increase in ICS =4 times the last prescribed ICS dose (or =50% of the prescribed ICS dose at V2 if background therapy withdrawal completed); Requiring use of systemic (oral and/or parenteral) steroid treatment; Requiring hospitalization or emergency room visit for asthma exacerbation	Until Week 12
Secondary	Pre-bronchodilator FEV1 (Forced expiratory volume in one second) change from baseline to EOT (end of treatment)		From baseline to Week 12
Secondary	Post-bronchodilator FEV1 change from baseline to EOT		From baseline to Week 12
Secondary	The absolute change in the percent predicted FEV1 from baseline to EOT (pre- and post-bronchodilator)		From baseline to Week 12
Secondary	Change from baseline in pre- and post-bronchodilator FEV1 and forced vital capacity [FVC] at each spirometry endpoint		From baseline until Week 12
Secondary	Change from baseline in peak expiratory flow [PEF] and forced expiratory flow [FEF] 25-75% at each spirometry endpoint		From baseline until Week 12
Secondary	Asthma Control Questionnaire-5 (ACQ-5) score change from baseline at EOT and at each assessment time point	The ACQ-5 is a questionnaire that measures the adequacy of asthma control and any changes in asthma control that may occur spontaneously or as a result of treatment. The ACQ-5 has five questions on the asthma symptoms and patients are asked to recall how their asthma has been during the previous week and to respond on a 7-point scale for each question (0 = no impairment, 6 = maximum impairment). The ACQ-5 score is the mean of the 5 questions and, therefore, between 0 (totally controlled) and 6 (severely uncontrolled). A high score indicates low asthma control.	From baseline until Week 12
Secondary	Asthma Quality of Life Questionnaire with Standardized Activities (AQLQ[S]) Self-administered score change from baseline at EOT and at each assessment time point	The AQLQ(S) was designed as a self-administered patient reported outcome to measure the functional impairments that are most troublesome to adolescents and adults =12 years of age as a result of their asthma. The instrument is comprised of 32 items, each rated on a 7-point Likert scales from 1 to 7. Higher scores indicate better quality of life.	From baseline until Week 12
Secondary	Change in Asthma Daytime Symptom Diary (ADSD) and Asthma Nighttime Symptom Diary (ANSD) scores from baseline to EOT and each week	ADSD and ANSD assess asthma severity based on patient self-report of asthma core symptoms, i.e., difficulty of breathing; wheezing; shortness of breath; chest tightness; chest pain; and cough. Both the ADSD and ANSD are composed of 6 items rated using an 11-point numerical rating scale (NRS) that ranges from 0 = None to 10 = As bad as you can imagine. The participants will record their daytime and nighttime asthma symptoms in an electronic diary, once in the evening and once in the morning, respectively.	From baseline until Week 12
Secondary	Plasma pharmacokinetic (PK) concentrations of rilzabrutinib in participants with asthma		Until Week 16
Secondary	Participants with Treatment Emergent Adverse Events		Until Week 16
Secondary	Change in numbers of inhalations/day of albuterol or levalbuterol for symptom relief from baseline to EOT and each week		From baseline until Week 12
