- Phase 2 Study for Potential Best-in-Class Therapeutic for Refractory Chronic Cough Patients Expected to Start in Mid-2019 -
LAVAL, QC, April 3, 2019 /CNW/ - BELLUS Health Inc. (TSX: BLU) ("BELLUS Health" or the "Company"), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of chronic cough and other hypersensitization-related disorders, today announced that the U.S. Food and Drug Administration ("FDA") has accepted the Company's Investigational New Drug ("IND") application, thus clearing the start of its Phase 2 study for BLU-5937 in chronic cough patients in the United States.
"We're very pleased that our first interactions with U.S. regulators have been positive and look forward to treating chronic cough patients with BLU-5937 shortly," commented Roberto Bellini, President and CEO of BELLUS Health. "Unlike other P2X3 antagonists, BLU-5937 is highly-selective, meaning that it can potentially reduce coughing, with very little to no effect on taste."
BELLUS Health expects to initiate the clinical Phase 2 study for BLU-5937 in chronic cough patients in mid-2019, with top-line results anticipated in mid-2020. This will be a randomized, double-blind, placebo-controlled crossover, and dose-escalation study to assess the efficacy, safety, and tolerability of BLU-5937, in addition to helping confirm the optimal dose regimen. Four doses of BLU-5937 will be tested: 25, 50, 100, and 200 mg twice-daily. The study is expected to be conducted in approximately 50 patients with refractory chronic cough at 10 to 12 clinical sites in the United States and the United Kingdom.
Phase 1 data reported in November 2018 showed that BLU-5937 is safe and well-tolerated, with very limited taste alterations at the anticipated therapeutic doses and a pharmacokinetic profile supporting twice-daily dosing.
BLU-5937, a highly selective P2X3 antagonist, has the potential to be a best-in-class therapeutic for refractory chronic cough patients. BLU-5937 has been shown to be highly selective (>1500 fold) for human P2X3 receptors versus P2X2/3 receptors.
The P2X3 receptor in the cough reflex pathway is a rational target for treating refractory chronic cough, and it has been validated in animal and human studies. With a modestly-selective P2X3 antagonist therapy for chronic cough, an adverse effect on taste perception is a well-known and widely-documented tolerability issue. The Company believes that a highly selective P2X3 antagonist can reduce coughing in patients with refractory chronic cough, while maintaining taste function by not inhibiting P2X2/3 receptors.
In addition to chronic cough, BLU-5937 may potentially have clinical benefit in other afferent hypersensitization-related disorders, such as visceral pain, hypertension, and migraine, among others. BELLUS Health is currently conducting preclinical studies in additional undisclosed indications.
