Reviva Pharmaceuticals Holdings, Inc. provided a regulatory update following a pre-New Drug Application (pre-NDA) meeting with the FDA regarding Brilaroxazine, a treatment for schizophrenia.

Reviva's strategy to commence the RECOVER-2 trial reflects a proactive approach to address FDA recommendations, demonstrating responsiveness to regulatory guidance. The successful execution of the trial hinges on securing financing, indicating potential funding implications for Reviva's stakeholders.

The constructive feedback received from the FDA signifies a collaborative relationship between Reviva and the regulatory agency, enhancing transparency and regulatory compliance in Brilaroxazine's development process.
