Minerva Neurosciences Receives Complete Response Letter from FDA for New Drug Application for Roluperidone for the Treatment of Negative Symptoms in Patients with Schizophrenia

BURLINGTON, Mass., Feb. 27, 2024 (GLOBE NEWSWIRE) -- Minerva Neurosciences, Inc. (Nasdaq: NERV), a clinical-stage biopharmaceutical company focused on the development of therapies to treat central nervous system disorders, announced today that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) to the Company’s New Drug Application (NDA) for roluperidone for the treatment of negative symptoms in patients with schizophrenia.

In the CRL, the FDA cited the following clinical deficiencies:

1. Although one study (MIN-101C03) demonstrated statistical significance on the primary efficacy endpoint, it is insufficient on its own to establish substantial evidence of effectiveness.
   
   
2. The NDA submission lacks data on concomitant antipsychotic administration.
   
   
3. The NDA submission lacks data needed to establish that the change in negative symptoms of schizophrenia with roluperidone treatment was clinically meaningful.
   
   
4. The submitted safety database included an inadequate number of subjects exposed to roluperidone at the proposed dose (64 mg) for at least 12 months.

To address these deficiencies, the FDA stated that Minerva must submit at least one additional positive, adequate, and well-controlled study to support the safety and effectiveness of roluperidone for the treatment of negative symptoms. Minerva must also provide additional data to demonstrate the safety and efficacy of roluperidone co-administered with antipsychotic medications, to support that observed effect on negative symptoms with roluperidone treatment corresponds to a clinically meaningful change, and to demonstrate the long-term safety of the proposed dose.

In addition to the clinical deficiencies described above, the FDA also provided comments on, among other items, clinical pharmacology, product quality, biopharmaceutics, and nonclinical issues.

“We are disappointed that the FDA has not approved roluperidone and will request a meeting to discuss the issues raised and attempt to address FDA’s feedback,” said Dr. Remy Luthringer, Executive Chairman and Chief Executive Officer of Minerva. “There is a critical need for a treatment for the negative symptoms of schizophrenia. We believe that roluperidone is a safe and effective therapy for negative symptoms of schizophrenia and we will review FDA’s feedback and consider our potential paths forward, including continuing to work closely with the FDA and providing any additional information as needed, with the goal of bringing this much needed therapy to patients and physicians.”

About roluperidone

Roluperidone has been shown to block serotonin, sigma and α-adrenergic receptors that are all involved in the regulation of important brain functions, including mood, cognition, sleep, and anxiety.

Roluperidone was designed to avoid a direct blockade of dopaminergic receptors (the key pharmacological target for first- and second-generation antipsychotics), while maintaining blockade of a specific subtype of serotonin receptor called 5-HT_2A (an additional key target of second-generation antipsychotics) as well as additional pharmacological targets (sigma₂ and adrenergic-α_1A).

About Schizophrenia and Negative Symptoms
Schizophrenia is a chronic, severe, and debilitating type of mental illness characterized by distortions in thinking, perception, emotions, language, sense of self and behavior. Schizophrenia affects 20 million people worldwide. (World Health Organization).

Negative symptoms can cause individuals with schizophrenia to withdraw from society, become disinterested or unable to complete tasks or feel pleasure. Negative symptoms are characterized by five constructs: blunted affect, alogia, avolition, anhedonia, and asociality (Marder and Galderisi, 2017).

Negative symptoms are the main cause of the poor functional outcome of patients suffering from schizophrenia (Harvey et al., 2020) and may also be one of the main reasons ultra-high risk adolescents may develop full blown schizophrenia (Gomes and Grace, 2017). There are currently no treatments approved for negative symptoms of schizophrenia in the US.

Minerva believes that research continues to emerge indicating that there is a large subgroup of patients with schizophrenia who have moderate to severe primary negative symptoms and minimal positive symptoms (Galderisi 2021) and have a low risk of worsening of positive symptoms even in the absence of antipsychotic treatments (Harrow 2013; Moilanen 2016;  Murray 2016;  Wils 2017; Wunderink 2013; Landolt 2016).
