Brilaroxazine exhibits positive results for Schizophrenia in Phase 3 trial

Reviva Pharmaceuticals Holdings, Inc. reported the successful completion of its key Phase 3 RECOVER trial for brilaroxazine, which represents a significant advancement for the treatment of schizophrenia. The outcomes have been promising in the trial, it assessed the safety, tolerability, and effectiveness of once-daily brilaroxazine, a serotonin-dopamine signaling modulator, in individuals with schizophrenia.

The pivotal trial achieved its primary aim, showing that the 50 mg dose of brilaroxazine reduced the Positive and Negative Syndrome Scale (PANSS) total score by 10.1 points when compared to a placebo, a statistically significant and clinically meaningful difference. This result represents a major breakthrough in the management of schizophrenia, a condition that affects over 24 million people globally.

In addition to the primary endpoint, brilaroxazine achieved statistically significant and clinically meaningful reductions in all major symptom domains and secondary endpoints at week 4 compared to the placebo. This includes positive and negative symptoms, personal and social performance, and PANSS Social Cognition. The broad efficacy profile, coupled with low discontinuation rates and favorable tolerability, suggests that brilaroxazine could address the limitations of current standards of care and offer a long-term treatment option for schizophrenia.

The clinical safety and tolerability findings of brilaroxazine further support its potential as a treatment option. No drug-related serious adverse events were observed, and there was no incidence of suicidal ideation. Additionally, there were no significant changes in body weight, blood glucose levels, lipid levels, or endocrine hormones when compared to the placebo. Akathisia and extrapyramidal symptoms were reported in less than 1% of patients taking brilaroxazine.

Reviva Pharmaceuticals plans to initiate a registrational Phase 3 RECOVER-2 trial in the first quarter of 2024, with the aim of supporting a New Drug Application (NDA) submission to the FDA in 2025. This advancement could significantly improve treatment options for individuals living with schizophrenia, providing hope for better management and enhanced quality of life.

Laxminarayan Bhat, the Founder, President, and CEO of Reviva, expressed excitement about the results and emphasized the multifaceted mechanism of action of brilaroxazine, which could potentially address key disease drivers like neuroinflammation. The long-term data from the ongoing OLE trial is expected to be reported in the fourth quarter of 2024, further adding to the growing body of evidence supporting brilaroxazine as a promising treatment for schizophrenia.
