ORYZON receives approval to start EVOLUTION Phase IIb trial with vafidemstat in schizophrenia – Yahoo Finance

Clinical Trial Application approved by Spanish Drug Agency

Primary objectives: to assess the effect of vafidemstat to address negative and cognitive symptoms in schizophrenia

Second Phase IIb study of vafidemstat in CNS disorders

MADRID, Spain and CAMBRIDGE, Mass., July 13, 2021 (GLOBE NEWSWIRE) -- Oryzon Genomics, S.A. (ISIN Code: ES0167733015, ORY), a clinical-stage biopharmaceutical company leveraging epigenetics to develop therapies in diseases with strong unmet medical need, announced today that it has received approval from the Spanish Drug Agency (AEMPS) for its Clinical Trial Application (CTA) to conduct a Phase IIb clinical trial with vafidemstat in patients with schizophrenia.

EVOLUTION (EudraCT No.: 2021-000350-26) is a multicenter, double-blind, randomized, placebo-controlled, 24-week Phase IIb trial to evaluate the efficacy and safety of vafidemstat in adult schizophrenia patients under stable antipsychotic therapy. The trial has two primary independent objectives: to assess the effect of vafidemstat on negative symptoms of schizophrenia, and to assess improvement on cognitive impairment associated with schizophrenia. To accommodate this second ambitious primary objective, patients will be treated for 6 months. The trial includes multiple primary and secondary endpoints focusing on negative and positive symptoms, as well as cognition. The trial will be conducted in 6-10 sites in Spain and aims to include 100 patients in total, with 50 patients in each arm. An interim analysis is foreseen to adjust the final number of patients needed to assess efficacy.

Dr. Carlos Buesa, President and CEO of Oryzon, said: The initiation of EVOLUTION is another important milestone for our CNS program following the recent start of the PORTICO Phase IIb trial of vafidemstat in borderline personality disorder. We are planning to further expand our clinical development of vafidemstat in personalized medicine trials in genetically defined subpopulations of certain CNS disorders.

Story continues

EVOLUTIONs scientific rationale is based on vafidemstats ability to inhibit LSD1, reducing aggression, enhancing sociability and mitigating social withdrawal, as demonstrated in several preclinical models (see Maes et al., PLOS ONE 2020 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0233468). Importantly, EVOLUTION builds on clinical data from the Phase IIa REIMAGINE trial, where vafidemstat reduced agitation-aggression in patients with attention deficit hyperactivity disorder, autism spectrum disorder and borderline personality disorder and showed positive global effects across these psychiatric disorders after 2 months of treatment. Vafidemstat has a favorable safety and tolerability profile in multiple Phase I/II clinical trials, with over 300 subjects treated, some for up to 24 months. Vafidemstat has not been associated with sedation, weight gain or extrapyramidal side effects, which are common in current antipsychotic therapy, nor with any other adverse events.

Oryzons Chief Medical Officer for CNS, Dr. Michael Ropacki, said: We believe that modulation of LSD1 has transformative potential in the treatment of various CNS diseases. There is growing evidence suggesting a connection between LSD1 and schizophrenia. We are excited in vafidemstats potential to treat the negative symptoms of schizophrenia and address cognitive impairment associated with schizophrenia, given there are no approved therapies for these symptoms.

Schizophrenia is a severe mental disorder characterized by positive symptoms such as delusions and hallucinations, negative symptoms including amotivation and social withdrawal, and cognitive symptoms such as deficits in working memory and cognitive flexibility. While new antipsychotics are available to improve the positive symptoms, no approved medications are available yet for the negative symptoms and cognitive impairment that are the most debilitating aspects of this disease. Prevalence of schizophrenia and related psychotic disorders in the US range between 0.25% and 0.64% of the population.

About Vafidemstat Vafidemstat (ORY-2001) is an oral, CNS optimized LSD1 inhibitor. The molecule acts on several levels: it reduces cognitive impairment, including memory loss and neuroinflammation, and at the same time has neuroprotective effects. In animal studies vafidemstat not only restores memory but reduces the exacerbated aggressiveness of SAMP8 mice, a model for accelerated aging and Alzheimers disease (AD), to normal levels and also reduces social avoidance and enhances sociability in murine models. In addition, vafidemstat exhibits fast, strong and durable efficacy in several preclinical models of multiple sclerosis (MS). Oryzon has performed two Phase IIa clinical trials in aggressiveness in patients with different psychiatric disorders (REIMAGINE) and in aggressive/agitated patients with moderate or severe AD (REIMAGINE-AD), with positive preliminary clinical results reported in both. Additional finalized Phase IIa clinical trials with vafidemstat include the ETHERAL trial in patients with Mild to Moderate AD, where a significant reduction of the inflammatory biomarker YKL40 has been observed after 6 months of treatment, and the pilot, small scale SATEEN trial in Relapse-Remitting and Secondary Progressive MS. Two Phase IIb trials in borderline personality disorder (PORTICO) and in schizophrenia patients (EVOLUTION) have been recently authorized. The company is also deploying a CNS precision medicine approach with vafidemstat in genetically-defined patient subpopulations of certain CNS disorders. Vafidemstat is also being explored in a Phase II in severe Covid-19 patients (ESCAPE) assessing the capability of the drug to prevent ARDS, one of the most severe complications of the viral infection.
