CUPERTINO, Calif., April 15, 2024 (GLOBE NEWSWIRE) -- Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (“Reviva” or the “Company”), a late-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), inflammatory and cardiometabolic diseases, today reported financial results for the full year ended December 31, 2023 and summarized recent business highlights.

“2023 was an exciting and productive year for Reviva that included significant progress in the late-stage development of our brilaroxazine program for schizophrenia. Building on the clinical momentum in 2023, we plan to initiate a registrational RECOVER-2 Phase 3 trial in the second quarter of 2024 which will replicate the successful trial design of our positive pivotal RECOVER-1 Phase 3 trial,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “In the year ahead, we also expect topline data from our 1-year OLE trial in the fourth quarter which will inform on the long-term safety and efficacy of brilaroxazine. With these important trials advancing and most non-clinical activities complete, we are targeting a potential NDA submission in the third quarter of 2025.”

Financial Results for 2023 and Restatement

For the year ended December 31, 2023, net loss was approximately $39.3 million, or $1.65 per share, compared to approximately $28.3 million, or $1.45 per share, for the year ended December 31, 2022 (as restated).

As of December 31, 2023, the Company’s cash and cash equivalents totaled approximately $23.4 million compared to approximately $18.5 million as of December 31, 2022.

The financial and related data for 2022 included in this press release, including in this “Financial Results” section and in the attached tables, is reflective of the restatement adjustments to the Company’s previously issued financial statements for the year ended December 31, 2022. As previously disclosed, on April 12, 2024, the Company concluded that the Company’s previously issued financial statements for the restatement periods, including the fiscal year ended December 31, 2022, should be restated to correct historical errors due primarily to the Company’s failure to properly review and evaluate expenses incurred in those clinical trial contracts resulting in the Company not properly accruing for clinical trial expenses that were incurred but for which invoices were not yet received. This impacted the Company’s previously-issued financial statements for the year ended December 31, 2022, which had understated by approximately $3.9 million certain R&D expenses and associated accrued liabilities, representing the under accrual of clinical expenses which would have otherwise been accounted for in the year ended December 31, 2023. The financial information in this press release has been updated to reflect the effects of the restatement adjustments.

About Brilaroxazine
Brilaroxazine is an in-house discovered new chemical entity with potent affinity and selectivity against key serotonin and dopamine receptors implicated in schizophrenia and its comorbid symptoms. Positive topline data from the global Phase 3 RECOVER-1 trial in schizophrenia demonstrated the trial successfully met all primary and secondary endpoints with statistically significant and clinically meaningful reductions across all major symptom domains at week 4 with 50 mg of brilaroxazine vs. placebo with a generally well-tolerated side effect profile comparable to placebo and discontinuation rates lower than placebo. Positive data from a clinical drug-drug interaction (DDI) study investigating the potential effect of CYP3A4 enzyme on brilaroxazine in healthy subjects supports no clinically significant interaction when combined with a CYP3A4 inhibitor. Reviva believes that a full battery of regulatory compliant toxicology and safety pharmacology studies has been completed for brilaroxazine. Reviva intends to develop brilaroxazine for other neuropsychiatric indications including bipolar disorder, major depressive disorder (MDD) and attention-deficit/hyperactivity disorder (ADHD).

Additionally, brilaroxazine has shown promising nonclinical activity for inflammatory diseases psoriasis, pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF) with mitigation of fibrosis and inflammation in translational animal models. Brilaroxazine has already received Orphan Drug Designation by the U.S. FDA for the treatment of PAH and IPF conditions.
