Confirmatory Phase 3 trial of roluperidone (MIN-101C19) ongoing with topline efficacy data expected 2H 2027

Scientific Advisory Board of leading experts in psychiatry and neuroscience established to guide the confirmatory Phase 3 trial of roluperidone

Roluperidone remains the only late-stage drug candidate for this high-need population

BURLINGTON, Mass., Aug. 07, 2026 (GLOBE NEWSWIRE) -- Minerva Neurosciences, Inc. (NASDAQ:NERV), a clinical-stage biopharmaceutical company focused on the development of therapies to treat central nervous system (CNS) disorders, today reported financial and business updates for the second quarter ended June 30, 2026.

"The psychiatry field has increasingly recognized negative symptoms as a distinct, undertreated driver of disability in schizophrenia, separate from the positive symptoms that current antipsychotics are designed to address," said Remy Luthringer, Ph.D., Chief Executive Officer of Minerva Neurosciences. "Roluperidone is the only late-stage candidate targeting negative symptoms directly. The C19 study, our ongoing confirmatory Phase 3 trial, is designed to confirm the effect we saw in our prior studies. We remain focused on execution and on track for topline efficacy data in the second half of 2027."

Roluperidone - potentially the First Treatment for Negative Symptoms of Schizophrenia

Minerva’s global confirmatory Phase 3 clinical trial of roluperidone for the treatment of negative symptoms of schizophrenia (the C19 Study) is designed to enroll 380 patients across approximately 40 clinical sites worldwide, including the United States (US) and multiple European countries.
The C19 Study follows productive discussions with the FDA on the overall design and efficacy assessments and builds directly on Minerva’s clinical success in the prior pivotal Phase 2b and Phase 3 trials (C03 and C07).
Phase A of the C19 Study will evaluate roluperidone 64 mg versus placebo to confirm the effect of roluperidone on primary negative symptoms at 12 weeks.
Phase B of the C19 Study will evaluate longer-term relapse of positive symptoms for roluperidone versus commonly prescribed antipsychotic medications for an additional 52-week period. The topline data from Phase B is expected in 2H 2028.

Roluperidone remains the only late-stage drug candidate for this high-need population.

Scientific Advisory Board

Minerva previously announced the formation of its Scientific Advisory Board (SAB) on June 1, 2026, comprising eight members with significant experience in psychiatry and neuroscience research, who will advise on the ongoing Phase 3 confirmatory trial of roluperidone as well as potential future pipeline programs.
Minerva recently added three additional members to its SAB, bringing the total to eleven members:

Christoph Correll, MD – Clinical Professor of Psychiatry and Molecular Medicine, The Donald and Barbara Zucker School of Medicine at Hofstra University;

Stefan Leucht, MD – Head of the Section for Evidence-Based Medicine in Psychiatry and Psychotherapy at the Department of Psychiatry and Psychotherapy, Technical University of Munich; and

Michael Sand, PhD, MPH – S2 Consulting LLC; formerly a board observer on the Minerva board of directors representing Boehringer Ingelheim.

Scientific Publication – Minerva team advancing thought leadership in schizophrenia research

Remy Luthringer, Ph.D. (Chief Executive Officer), Michael Davidson, MD (Chief Medical Officer) and Jonathan Rabinowitz, PhD (biostatistical consultant) continue to advance thought leadership in schizophrenia research through coauthoring findings from a longitudinal analysis of 1,139 patients enrolled in the CATIE trial, one of the largest and most influential studies conducted in schizophrenia (Speyer et al., 2026). The analysis found that patients with greater negative symptom severity experienced a lower likelihood of short-term worsening of positive symptoms.
The findings suggest a relatively stable illness course among individuals with more severe negative symptoms. These results have implications for prognosis and treatment planning, while underscoring the persistent functional burden imposed by negative symptoms despite lower exacerbation risk.

Second Quarter and Six Months 2026 Financial Results

Research and development (R&D) expense: For the three months ended June 30, 2026 and 2025, R&D expense was $7.2 million and $1.3 million, respectively. For the six months ended June 30, 2026 and 2025, R&D expense was $12.4 million and $2.7 million, respectively. R&D expense was higher versus the prior year period in both the three and six months ended June 30 primarily due to expenses related to the C19 trial as well as higher compensation costs.

General and administrative (G&A) expense: For the three months ended June 30, 2026 and 2025, G&A expense was $3.5 million and $2.1 million, respectively. G&A expense was higher versus the prior year period primarily due to higher professional service fees and compensation costs. For the six months ended June 30, 2026 and 2025, G&A expense was $14.9 million and $4.6 million, respectively. G&A expense was higher versus the prior year period primarily due to higher professional service fees as well as costs related to a severance agreement in the first quarter, which included a $6.6 million one-time, non-cash charge for the modification of the terms of previously granted stock options.

Other income and expense: For the three months ended June 30, 2026 and 2025, investment income was $0.6 million and $0.1 million, respectively. For the six months ended June 30, 2026 and 2025, investment income was $1.2 million and $0.3 million, respectively. The increase is primarily due to higher cash equivalents and marketable securities balances.

Change in Fair Value of Warrant Liability¹: For the three months ended June 30, 2026, the Company recorded a non-cash gain of $27.6 million related to the change in fair value of the warrant liability. For the six months ended June 30, 2026, the Company recorded a non-cash loss of $81.8 million related to the change in fair value of the warrant liability. The gain and loss, respectively, on the change in fair value of the warrant liability is related to the warrants issued in conjunction with the October 2025 private placement.

Total Liabilities: Under U.S. Generally Accepted Accounting Principles ("GAAP"), for the periods ended June 30, 2026 and December 31, 2025, total liabilities were $296.6 million and $233.8 million, respectively. Excluding the warrant liability and liability related to the sale of future royalties, non-GAAP total liabilities* were $4.0 million and $2.3 million for the periods ended June 30, 2026 and December 31, 2025, respectively.

Net Income (Loss): For the three months ended June 30, 2026, Minerva recorded GAAP net income of $17.5 million, or $0.36 per basic share and $(0.14) per diluted share, compared to a net loss of $3.3 million, or $(0.43) per basic and diluted share, for the three months ended June 30, 2025. The quarter's GAAP net income was driven by a $27.6 million non-cash gain on the change in fair value of the warrant liability¹; excluding that gain and stock-based compensation expense, adjusted (non-GAAP) net loss* for the quarter was $7.8 million, compared to an adjusted net loss* of $3.0 million in the prior-year period.

For the six months ended June 30, 2026, Minerva recorded a GAAP net loss of $107.9 million, or $2.38 per basic and diluted share, compared to a net loss of $7.0 million, or $0.93 per basic and diluted share, for the six months ended June 30, 2025. The six-month loss reflects a $81.8 million non-cash loss on the change in fair value of the warrant liability¹, the inverse of the gain recorded in the second quarter, meaning the liability's fair value moved unfavorably in the first quarter by more than it moved favorably in the second. Excluding that loss and stock-based compensation expense, adjusted (non-GAAP) net loss* for the six months was $15.1 million, compared to an adjusted net loss* of $6.4 million in the prior year period.

Cash Position: Cash, cash equivalents, marketable securities and restricted cash at June 30, 2026 was approximately $75.4 million, as compared to $82.4 million at December 31, 2025.

About the Phase 3 MIN-101C19 Trial

Minerva’s Phase 3 MIN-101C19 trial (the C19 Study) is designed to enroll 380 adults aged 18–55 with moderate to severe negative symptoms of schizophrenia, confirmed by a Positive and Negative Syndrome Scale (PANSS) negative subscale score greater than 20 and stable positive symptoms for at least six months. The C19 Study utilizes a two-part design. The overall objective of the study is to confirm the effect of roluperidone on primary negative symptoms at 12 weeks compared to placebo (Phase A) and to evaluate longer-term relapse of positive symptoms compared with commonly prescribed antipsychotic medications for an additional 52 weeks (Phase B).

The trial is designed to minimize variability and maximize sensitivity to treatment effect, including standardized assessments, and comprehensive caregiver engagement. The trial’s operational model includes intensive rater training, real-time monitoring of scoring data, and structured caregiver outreach to support safety tracking, functional assessments, and adherence.

Phase A is a 12-week, randomized, double-blind, placebo-controlled phase during which patients will receive 64 mg of roluperidone or placebo to evaluate the primary endpoint: change from baseline in the Marder Negative Symptoms Factor Score (NSFS), which is a factor-analytic composite created from selected PANSS items. The sole key secondary endpoint is the change from baseline in the Personal and Social Performance (PSP) total score. Other secondary endpoints include a broad set of additional clinical measures, including PANSS subscales, Clinical Global Impression – Severity (CGI-S), Clinical Global Impression – Improvement (CGI-I), the Calgary Depression Scale, avolition-specific analyses, and patient and caregiver treatment-satisfaction ratings. Topline data from Phase A of the trial is expected in the second half of 2027.

Phase B extends the trial for an additional 52 weeks using a double-dummy, active-controlled, randomized design comparing continued roluperidone with three commonly prescribed antipsychotic medications (risperidone, aripiprazole, or olanzapine). This phase is designed to compare relapse rates between treatment groups. Relapses of positive symptoms will be evaluated using a rigorous, multi-component definition incorporating psychometric endpoints based on PANSS score worsening, and clinically meaningful events such as hospitalization or dangerous behavior. Topline data from Phase B of the trial is expected in the second half of 2028.

Non-GAAP Financial Measures

In addition to the financial information presented in this release in accordance with accounting principles generally accepted in the United States of America (GAAP), Minerva also presents adjusted non-GAAP financial measures.

Non-GAAP financial measures are included with the intent of providing investors with an understanding of Minerva’s historical financial results and trends and to facilitate comparisons between periods. In addition, these non-GAAP financial measures are among the indicators that Minerva’s management uses for planning and forecasting purposes and measuring Minerva’s performance. Minerva believes that these non-GAAP financial measures, when considered together with U.S. GAAP measures, can enhance the understanding of its financial and operating performance. Non-GAAP financial measures have no standardized meaning and investors are cautioned that, unlike financial measures prepared in accordance with U.S. GAAP, non-GAAP measures may not be comparable with the calculation of similar measures for other companies. The limitations of using non-GAAP financial measures as performance measures are that they provide a view of Minerva’s results of operations without including all events during a period and may not provide a comparable view of Minerva’s performance to other companies in the biopharmaceutical industry. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate the business.

Non-GAAP total liabilities is defined as GAAP total liabilities, excluding warrant liability and liability related to the sale of future royalties.

Non-GAAP adjusted net income (loss) is defined as GAAP net income (loss), adjusted to exclude non-cash items related to: (i) stock-based compensation expense and (ii) changes in fair value of warrant liability.
