Reviva Pharmaceuticals Announces Successful Completion of Pre-IND Meeting with FDA on Brilaroxazine for the Treatment of Idiopathic Pulmonary Fibrosis (IPF)

June 3, 2019

CUPERTINO, Calif.--()--Reviva Pharmaceuticals, Inc. (Reviva), a privately held, clinical stage pharmaceutical company today announced that it has successfully completed a pre-Investigational New Drug (IND) Application meeting with the U.S. Food and Drug Administration (FDA) for its drug candidate brilaroxazine, which is being developed for the treatment of idiopathic pulmonary fibrosis (IPF). The FDA has recently granted Orphan Drug Designation to brilaroxazine for treating patients with IPF.

A pre-IND meeting provides an opportunity for an open communication between the sponsor and the FDA to discuss the IND development plan and to obtain the agency’s guidance for clinical studies for the sponsor’s new drug candidate. The FDA has reviewed brilaroxazine IND enabling preclinical data, and clinical phase 1 study results and phase 2 study plan for IPF. The FDA addressed Reviva’s questions and provided guidance on the brilaroxazine clinical development plan for IPF.

“We are very pleased with the outcome of the pre-IND meeting with the FDA,” said Laxminarayan Bhat, PhD. Reviva’s Founder, President and Chief Executive Officer. “We look forward to initiating brilaroxazine phase 2 study for IPF soon.”

About Idiopathic Pulmonary Fibrosis (IPF)

IPF is a progressive, debilitating and fatal lung disease that affects approximately 3 million people worldwide. IPF is characterized by inflammation and fibrosis of the lungs, hindering the ability to process oxygen and causing shortness of breath. Mortality from IPF is increasing steadily worldwide with a median survival time from diagnosis of 2-5 years. It is estimated that there will be between 28,000 and 65,000 deaths in Europe and between 13,000 and 17,000 deaths in the United States from IPF per year. Currently, the treatment options are limited and there is no cure for IPF.

About Brilaroxazine

Brilaroxazine is a new chemical entity (NCE) that acts on serotonin signaling pathways. Whilst dysfunctional serotonin (5-HT) signaling in the brain contributes to the pathophysiology of neuropsychiatric and neurological diseases, in the lung it leads to IPF and pulmonary arterial hypertension (PAH). Serotonin signaling derived from activated 5-HT2A/2B/7 receptors in the lung has been reported to mediate inflammation, fibrosis and proliferation, and pulmonary hypertension that are hallmarks of IPF and PAH. Brilaroxazine is a potent inhibitor of the 5-HT2A/2B/7 receptors and, consequently, attenuates these functional changes in a series of highly recognized translational animal models proven to emulate IPF and PAH conditions in humans.

PAH and neuropsychiatric symptoms are among the major comorbidities in patients with IPF. Reviva has already successfully completed a multicenter, multinational phase 2 clinical study for brilaroxazine in patients with schizophrenia and schizoaffective disorders where it demonstrated robust efficacy with remission in acute schizophrenia and promising efficacy for comorbid negative, cognition, depression and mood symptoms. Moreover, brilaroxazine showed an excellent safety and tolerability profile compared to the placebo with no weight gain, metabolic, cardiac or movement side effects, which resulted in good acceptance and compliance. Data from preclinical and clinical studies with brilaroxazine are currently available in several published research articles in peer reviewed journals (
