CUPERTINO, Calif., April 26, 2021 (GLOBE NEWSWIRE) -- Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (along with its subsidiaries, “Reviva” or the “Company”), a clinical-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), cardiovascular, metabolic, and inflammatory diseases, today announced the full details of its Phase 2 clinical trial for its lead drug candidate, RP5063 (brilaroxazine) for Acute Schizophrenia.
Brilaroxazine has a unique pharmacology profile against key serotonin (5-HT) and dopamine (D) receptors, which Reviva believes can modulate and stabilize the D/5-HT system. Brilaroxazine demonstrated high affinity and selectivity for key serotonin receptors (5-HT1A/2A/2B/7), as it is pharmacologically different from other antipsychotics through its combination of potent affinity and selectivity for target receptors implicated for schizophrenia and its comorbid symptoms.
In its randomized, double-blind, placebo-controlled, multicenter Phase 2 trial to assess the safety and efficacy of brilaroxazine in 234 subjects with acute exacerbation of schizophrenia or schizoaffective disorder, brilaroxazine met its primary endpoint, which was reduction in total Positive and Negative Syndrome Scale (PANSS) at the end of the treatment from baseline versus placebo. The drug candidate also met all safety endpoints including clinical, labs, body weight, prolactin, lipids, fasting glucose, and EKG. The PANSS total score was reduced by 20 points, a statistically significant treatment difference from the placebo. Brilaroxazine also mitigated positive symptoms and negative symptoms, and improved social functioning and cognition. Importantly, the FDA has agreed to consider a potential ‘Superior Safety’ label claim, if there is a positive outcome on a relevant endpoint in a pivotal Phase 3 clinical study in schizophrenia.
Chief Executive Officer, Laxminarayan Bhat, PhD, commented: “Schizophrenia affects about 3.5 million people in the U.S. and 20 million globally, yet we believe there are currently no therapies that adequately address the complex mix of positive symptoms, negative symptoms, mood, and cognitive impairment associated with Schizophrenia. We are very excited about our promising phase 2 clinical data and the potential for our drug candidate to address major unmet needs associated with current treatments.”
Dr. Bhat also added, “In addition to the suboptimal efficacy of current antipsychotic treatments, patients also suffer from side effects and poor tolerability, which include side effects such as akathisia, weight gain/obesity, diabetes, high cholesterol, hypothyroidism and sexual dysfunction. Moreover, we estimate discontinuation/non-compliance rates at 30 to 45% in the acute phase treatment and up to 74% in the long-term treatment of stable schizophrenia patients. Our phase 2 data shows that brilaroxazine potentially can mitigate the negative side effects of current treatments and ultimately that would hopefully improve patient’s compliance to the treatment. We have published several research papers on the results of brilaroxazine’s pharmacology, and the clinical phase 1 and phase 2 studies in peer reviewed journals (https://revivapharma.com/publications/).
