The complaint alleges that throughout the classroom, defendants made materially false and / or misleading statements and failed to advise investors that BLU-5937 had a much higher risk of not demonstrating effectiveness in chronic coughing. Accordingly, despite Merck’s successful Phase 2 study, BLU-5937 had a high risk of failing the Phase 2 study.

Before the markets opened on July 6, 2020, defendants revealed the truth about BLU-5937’s effectiveness. They announced that the drug had failed a Phase 2 study in chronic cough patients who were unsuccessful with other treatments. In particular, BLU-5937 was not significantly better than placebo in reducing the frequency with which patients coughed. The phase 2 study showed a “clinically meaningful and statistically highly significant effect only in a subset of patients with high cough counts (approximately 32 per day). Therefore, the company planned a phase 2b study that focused on these patients.

In this news, indicating that BELLUS had fallen even further behind Merck in developing an FDA-cleared treatment for refractory chronic cough, the company’s share price fell over 75% and closed on July 8, 2020 due to high trading volume at $ 2.97.
