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 Background therapy of ICS/LABA will be withdrawn during the 12week randomized treatment period and resumed at the end of the IMP treatment period, as outlined below: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

Primary Outcome Measures :
- Proportion of participants with an LOAC event during the treatment period [ Time Frame: Until Week 12 ]
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
Secondary Outcome Measures :
- Pre-bronchodilator FEV1 (Forced expiratory volume in one second) change from baseline to EOT (end of treatment) [ Time Frame: From baseline to Week 12 ]
- Post-bronchodilator FEV1 change from baseline to EOT [ Time Frame: From baseline to Week 12 ]
- The absolute change in the percent predicted FEV1 from baseline to EOT (pre- and post-bronchodilator) [ Time Frame: From baseline to Week 12 ]
- Change from baseline in pre- and post-bronchodilator FEV1 and forced vital capacity [FVC] at each spirometry endpoint [ Time Frame: From baseline until Week 12 ]
- Change from baseline in peak expiratory flow [PEF] and forced expiratory flow [FEF] 25-75% at each spirometry endpoint [ Time Frame: From baseline until Week 12 ]
- Asthma Control Questionnaire-5 (ACQ-5) score change from baseline at EOT and at each assessment time point [ Time Frame: From baseline until Week 12 ]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.
- Asthma Quality of Life Questionnaire with Standardized Activities (AQLQ[S]) Self-administered score change from baseline at EOT and at each assessment time point [ Time Frame: From baseline until Week 12 ]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.
- Change in Asthma Daytime Symptom Diary (ADSD) and Asthma Nighttime Symptom Diary (ANSD) scores from baseline to EOT and each week [ Time Frame: From baseline until Week 12 ]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.
- Plasma pharmacokinetic (PK) concentrations of rilzabrutinib in participants with asthma [ Time Frame: Until Week 16 ]
- Participants with Treatment Emergent Adverse Events [ Time Frame: Until Week 16 ]
- Change in numbers of inhalations/day of albuterol or levalbuterol for symptom relief from baseline to EOT and each week [ Time Frame: From baseline until Week 12 ]
