Milan, Italy, May 3, 2023, 7am CET – Newron Pharmaceuticals S.p.A. (“Newron”) (SIX: NWRN, XETRA: NP5), a biopharmaceutical company focused on the development of novel therapies for patients with diseases of the central and peripheral nervous system (CNS), announced that it will present six posters in various presentation formats at the upcoming 34th CINP World Congress of Neuropsychopharmacology, taking place 7-10 May 2023 at the Fairmont The Queen Elizabeth hotel in Montreal, Québec, Canada, and the 2023 Congress of the Schizophrenia International Research Society (SIRS) taking place 11-15 May 2023 at The Westin Harbour Castle in Toronto, Ontario, Canada.
The posters and presentations will feature first-time disclosures of additional results from study 014/015, an international, randomized, open label, rater-blinded study of evenamide as an add-on to an antipsychotic (excluding clozapine) in patients with moderate to severe TRS not responding to their current antipsychotic medication.
These results offer further analyses of the multidimensional efficacy of glutamate release modification in patients with TRS and the characteristics of early and late responders in patients with TRS, thus deepening the understanding of the potential long-term benefits an innovative add-on therapy that modifies glutamate release could offer to TRS patients.
Presentations at the CINP, Montreal: (all times EDT)

These two renowned international congresses represent essential forums of scientific dialogue for key opinion leaders. For this reason, Newron will host an advisory committee meeting with clinical experts on treatment-resistant schizophrenia, insights of which will contribute to the design of a potentially pivotal, multinational, randomized, placebo-controlled trial with evenamide in patients with TRS.
About treatment-resistant schizophrenia (TRS)
A significant proportion of patients with schizophrenia show virtually no beneficial response to antipsychotics (APs) despite adequate treatment, leading to a diagnosis of treatment-resistant schizophrenia (TRS). TRS is defined as no, or inadequate, symptomatic relief despite treatment with therapeutic doses of two APs from two different chemical classes for an adequate period. About 15% of patients develop TRS from illness onset, and about one-third of patients overall. Increasing evidence supports abnormalities in glutamate neurotransmission in TRS, not targeted by current APs, along with normal dopaminergic synthesis, to explain the lack of benefit of most typical and atypical antipsychotics.
About study 014/015
Study 014 is a six-week, randomized, rater-blinded study being conducted at multiple sites in three countries (India, Italy and Sri Lanka). Study 014 has completed the enrollment of 161 patients with TRS on a stable, therapeutic dose of a single antipsychotic other than clozapine. The primary objective of the study is to evaluate the safety and tolerability of evenamide given orally at three fixed doses (7.5, 15 and 30 mg bid). The assessment of preliminary efficacy is based on changes from baseline in the Positive and Negative Syndrome Scale (PANSS). Changes from baseline in Clinical Global Impression of Change (CGI-C), Severity of Illness (CGI-S), and Strauss-Carpenter Level of Functioning (LOF) scale, are secondary objectives. Study 015 is the extension study to determine the long-term benefits of glutamate release inhibition. Seventy-seven (77) of the first 100 patients completed the 1-year of treatment with evenamide, 16 discontinued the study early, two due to adverse events (one patient due to fever, vomiting, and nausea, the other due to somnolence, reduced concentration and increased sweating), the other 14 due to withdrawal of consent or lost to follow up.
Evenamide, an orally available new chemical entity, specifically blocks voltage-gated sodium channels (VGSCs) and is devoid of biological activity at >130 other CNS targets. It normalizes glutamate release induced by aberrant sodium channel activity (veratridine-stimulated), without affecting basal glutamate levels, due to inhibition of VGSCs. Combinations of ineffective doses of evenamide and other APs, including clozapine, were associated with benefit in animal models of psychosis, suggesting synergies in mechanisms that may provide benefit in patients who are poor responders to current APs, including clozapine.
