Minerva Neurosciences Receives FDA Requirement for Confirmatory Study of Roluperidone in Schizophrenia Treatment and Initiates Strategic Review Process

FDA confirms requirement for confirmatory study of roluperidone for the treatment of negative symptoms in schizophrenia

Evaluation of strategic alternatives

BURLINGTON, Mass., Aug. 14, 2025 (GLOBE NEWSWIRE) -- Minerva Neurosciences, Inc. (Nasdaq: NERV), a clinical-stage biopharmaceutical company focused on the development of therapies to treat central nervous system disorders, today provided business updates.

FDA Discussions & Roluperidone Update

The Company has had multiple interactions with the FDA following receipt of the Complete Response Letter (CRL) for its New Drug Application (NDA) in February 2024 and the FDA has confirmed the requirement for an additional confirmatory clinical trial to address the deficiencies cited in the CRL and resubmit the NDA.

As in the two previous studies (C03 and C07), the required confirmatory clinical trial would include patients diagnosed with schizophrenia who present with impairing negative symptoms and stable positive symptoms. Patients would be selected based on stable positive symptoms and impairing negative symptoms for the six months prior to entering the trial. Minerva agreed with FDA that best efforts will be made to secure 25-30% of patients from USA (subject to competitive recruitment). The FDA has confirmed that roluperidone can be studied in monotherapy where patients would receive a double-blinded single daily 64 mg dose of roluperidone or placebo. The FDA has also confirmed that, the primary endpoint would be the change from Baseline in PANSS Marder negative symptoms factor score (NSFS) at 12 weeks of treatment with roluperidone compared to placebo. The FDA advised that, to support a monotherapy indication, it would be necessary to assess relapses on an observational basis for at least 52 weeks in patients treated in monotherapy with roluperidone, placebo or antipsychotics. The FDA has stated that it would consider a resubmission of the NDA that included a double-blind, placebo- or active-controlled trial of roluperidone with a duration of at least 52 weeks.

The trial’s potential sole key secondary endpoint would be the comparison of the change from Baseline in the Personal and Social Performance scale total score (PSP) to Week 12, which is a scale to assess patients’ social functioning. The trial will also potentially measure the change from Baseline in Clinical Global Impression of Severity (CGI-S), change from Baseline in NSFS, PSP, and CGI-S at earlier timepoints and safety & tolerability.

The FDA has agreed that an adjunctive trial with antipsychotics would not be required for resubmission of the NDA if Minerva could provide robust, controlled data demonstrating the efficacy and safety of long-term monotherapy with roluperidone in subjects with negative symptoms of schizophrenia.

Second Quarter 2025 Financial Results

Research and development (R&D) expense : For the three months ended June 30, 2025 and 2024, R&D expense was $1.3 million and $3.9 million, respectively. R&D expense was lower versus the prior year period primarily due to lower costs associated with our drug substance validation campaign and lower consultant fees. For the six months ended June 30, 2025 and 2024, R&D expense was $2.7 million and $8.0 million, respectively. R&D expense was lower versus the prior year period primarily due to lower costs associated with our drug substance validation campaign, costs for the C18 study, consultant fees, and lower compensation expenses.

General and administrative (G&A) expense : For the three months ended June 30, 2025 and 2024, G&A expense was $2.1 million and $2.4 million, respectively. For the six months ended June 30, 2025 and 2024, G&A expense was $4.6 million and $4.9 million, respectively. G&A expense was lower versus the prior year periods primarily due to lower professional service fees.

Non-cash interest expense : For the three and six months ended June 30, 2025, non-cash interest expense for the sale of future royalties was zero, as compared to $2.3 million and $4.6 million for the three and six months ended June 30, 2024, respectively. Non-cash interest expense was lower versus the prior year periods due to revising our estimates for the timing and amount of future royalty payments to be received under the royalty arrangement. During the third quarter of 2024, we adjusted the carrying amount of our liability related to the sale of future royalties to the initial payment of $60 million. This adjustment resulted in the recognition of $26.6 million in other income during the third quarter of 2024, representing the amount of non-cash interest expense amortized through June 30, 2024.

Net loss : Net loss for the three and six months ended June 30, 2025 was $3.3 million and $7.0 million, or a basic and diluted net loss per share of $0.43 and $0.93, respectively, as compared to a net loss for the three and six months ended June 30, 2024 of $8.2 million and $16.8 million or a basic and diluted net loss per share of $1.09 and $2.22, respectively.

Cash Position: Cash, cash equivalents and restricted cash at June 30, 2025 were approximately $15.3 million, as compared to $21.5 million at December 31, 2024.
