Summary

This is a parallel, treatment, Phase 2, double-blind, 2 arm, 12-week Proof of Concept (PoC) study 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 inhaled 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 Background therapy of ICS/LABA will be withdrawn during the 12week randomized treatment period and resumed at the end of the IMP treatment period, as outlined below: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.

Inclusion Criteria

A physician diagnosis of asthma for at least 12 months based on the Global Initiative for Asthma (GINA) 2018,2019, 2020 Guidelines
Participants with existing treatment with at least moderate to high doses of ICS therapy in combination with a LABA as second controller for at least 3 months with a stable dose ≥1 month prior to Visit 1
Participants with prebronchodilator FEV1 >40% of predicted normal at Visit 1/Screening. Prebronchodilator FEV1 ≥50% but ≤85% of predicted normal at Visit 2/Baseline
Participants with reversibility of at least 12% and 200 mL in FEV1 15 to 30 minutes after administration of 2 to 4 puffs (200-400 mcg) of albuterol/salbutamol or levalbuterol/levosalbutamol during screening or documented history of a reversibility test that meets this criteria within 12 months prior to Visit 1 or documented positive response to methacholine challenge (a decrease in FEV by 20% [PC20] of <8mg/mL) within 12 months prior to Visit 1/Screening is considered acceptable to meet this inclusion criterion
Participants must have experienced, within 2 years prior to Visit 1, any of the following asthma exacerbation events at least once: Treatment with a systemic steroid (oral or parenteral) for worsening asthma OR Hospitalization or emergency medical care visit for worsening asthma
Body mass index (BMI) ≥17.5 and ≤40 kg/m2
All Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies

Exclusion Criteria

History of serious infections requiring intravenous therapy with the potential for recurrence or currently active moderate to severe infection at Screening (Grade 2 or higher) including active coronavirus disease 2019 (COVID-19)
Chronic lung disease (for example, chronic obstructive pulmonary disease [COPD], or idiopathic pulmonary fibrosis [IPF]) which may impair lung function, or another diagnosed pulmonary or systemic disease associated with elevated peripheral eosinophil counts, for e.g. eosinophilic granulomatosis with polyangiitis
History of life-threatening asthma (i.e., severe exacerbation that requires intubation)
Participants with any of the following events within the 4 weeks prior to their Screening Visit 1 or during the screening period: Treatment with 1 or more systemic (oral and/or parenteral) steroid bursts for worsening asthma OR Hospitalization or emergency medical care visit for worsening asthma
Asthma Control Questionnaire 5-question version (ACQ-5) score <1.25 or >3.0 at V2/randomization. During the screening period an ACQ-5 of up to ≤4 is acceptable

Previous smoker with a smoking history >10 pack-years
Current or chronic history of liver disease
Known hepatic or biliary abnormalities
Symptomatic herpes zoster within 3 months prior to screening
Refractory nausea and vomiting, malabsorption, external biliary shunt, or significant bowel resection that would preclude adequate rilzabrutinib/placebo absorption

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
Is not up-to-date with recommended vaccinations per local guidelines

Use of inhalers other than ICSs, LABAs, and short-acting beta agonists (no long-acting muscarinic antagonists (LAMAs) or mucolytics) and leukotriene receptor antagonists (montelukast, zafirkulast) during the study period
Participants who have received bronchial thermoplasty within 2 years prior to Visit 1 or plan to begin therapy during the screening period or the randomized treatment period
Use of proton pump inhibitor drugs such as omeprazole and esomeprazole within 3 days of Day 1
Use of known strong-to-moderate inducers or inhibitors of CYP3A within 14 days or 5 half-lives (whichever is longer) of Study Day 1 and until the end of the active treatment period
Live vaccine except Bacille Calmette Guerinn-vaccination within 28 days prior to Day 1 or plans to receive one during the trial; Calmette Guerin-vaccination within 12 months prior to Screening
COVID-19 vaccine within 14 days prior to Study Day 1
Previous use of a Bruton tyrosine kinase (BTK) inhibitor
Has received any investigational drug (or is currently using an investigational device) within the 30 days before Day 1, or at least 5 times the respective elimination half-life time (whichever is longer)
