Aptinyx to Initiate Phase 2b Study of Post-traumatic Stress Disorder Drug, Discloses Statistical Error In Previously Reported Phase 1 Data

Aptinyx Inc. APTX announced that it has finalized the design of its Phase 2b program for NYX-783 in patients with post-traumatic stress disorder after having received the minutes from its recent Type C meeting with the FDA.

The company expects to initiate the Phase 2b program in the fourth quarter of 2021.

Aptinyx also announced that, in its preparation for Phase 2b, it identified a statistical error made by the contract research organization that performed the statistical analysis of the previously completed exploratory Phase 2 study in PTSD. Accordingly, the company is providing updated statistical analysis for the exploratory Phase 2 study, which has no impact on the study conclusions.

The revised mixed model for repeated measures p-values are higher than previously reported in October 2020. The CRO confirmed the error in late May and reported the updated statistical analysis to the company in June.

The stock slipped 9.74% to $3.15 in after-hours trading.

Regeneron's Antibody Cocktail Found Effective Against Hospitalized Severe COVID-19 Patients In a Large U.K. Study

Regeneron Pharmaceuticals, Inc. REGN announced positive results from the largest trial assessing any monoclonal antibody treatment in patients hospitalized with severe COVID-19.

The UK RECOVERY trial found that adding investigational REGEN-COV to usual care reduced the risk of death by 20% in patients who had not mounted a natural antibody response on their own against SARS-CoV-2, compared to usual care on its own.

"There was great uncertainty about the value of antiviral therapies in late-stage COVID-19 disease. It is wonderful to learn that even in advanced COVID-19 disease, targeting the virus can reduce mortality in patients who have failed to mount an antibody response of their own," said Sir Peter Horby, joint chief investigator for the RECOVERY trial.

Regeneron said it is in discussions with the FDA to expand the current emergency use authorization to other populations, including the prevention and hospitalized patient settings. The company expects to submit a full biologics license application for REGEN-COV this summer.
