MADRID, SPAIN and CAMBRIDGE, MA, UNITED STATES, March 15th, 2021 - 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, announces a constructive and successful  pre-IND meeting with the FDA for the clinical development of vafidemstat, a selective inhibitor of the  epigenetic target LSD1, in Borderline Personality Disorder (BPD).

Based on the FDA’s feedback from the meeting, Oryzon will proceed to file an IND application in the next  weeks with the aim to initiate the PORTICO Phase IIb clinical study in the US in 1H2021. PORTICO (EudraCT No.: 2020-003469-20) is a multicenter, double-blind, randomized, placebo-controlled Phase IIb trial to evaluate the efficacy and safety of vafidemstat in BPD patients. The two primary independent objectives of the trial will be a reduction of aggression and agitation and an overall improvement of BPD. The study aims to include 156 patients in total, with 78 patients in each arm, and has an adaptive design with a pre-defined interim analysis to adjust the sample size in case of excessive variability around the endpoints or an unexpectedly high placebo rate. The study is already approved in Europe by the Spanish Medicinal Agency (AEMPS).

PORTICO builds on clinical data from the Phase IIa REIMAGINE trial, where vafidemstat reduced agitationaggression in patients with attention deficit hyperactivity disorder (ADHD), autism spectrum disorder  (ASD) and BPD after 2 months of treatment, and from the Phase IIa REIMAGINE-AD trial, where vafidemstat reduced agitation-aggression in patients with severe and moderate Alzheimer's disease after 6 months of treatment. Vafidemstat has proven safe and well-tolerated across multiple clinical trials in approximately 300 treated subjects, some on continuous therapy for up to 18 months. PORTICO’s scientific rationale is based on vafidemstat’ s ability to inhibit LSD1 and modulate aggression and sociability, as tested in several preclinical models (see Maes et al., PLOS ONE 2020, https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0233468).

Oryzon has one of the strongest portfolios in the field. Oryzon’s LSD1 program has rendered two compounds, vafidemstat and iadademstat, in Phase II clinical trials. In addition, Oryzon has ongoing programs for developing inhibitors against other epigenetic targets. Oryzon has a strong technological platform for biomarker identification and performs biomarker and target validation for a variety of malignant and neurological diseases. Oryzon has offices in Spain and the United States. Oryzon is one of the most liquid biotech stocks in Europe with +90 M shares negotiated in 2020 (ORY:SM / ORY.MC / ORYZF US OTC mkt).

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 Alzheimer’s 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. A Phase IIb trial in borderline personality disorder (PORTICO) has been recently authorized and the company is preparing a Phase IIb trial in schizophrenia patients (EVOLUTION). 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.

About Borderline Personality Disorder

Borderline Personality Disorder (BPD) is one of the most complex, functionally debilitating and costly psychiatric illnesses for health care systems, affecting between 0.5 and 1.6% of the general population. BPD patients often experience emotional instability, impulsivity, irrational beliefs and distorted perception, and intense but unstable relationships with others. Up to 10% of those affected die by suicide. Psychotherapy is the first-line treatment and while medications may be prescribed to treat specific symptoms, there is no FDA-approved treatment for BPD patients. It is estimated that around 1.4 million BPD patients in the U.S. are being treated with off-label drugs, approved for other conditions and which manage symptoms rather than the disease itself.
