Additional Data Analyses From Phase IIb Trial of MIN-101 in Schizophrenia Underscore Benefit in Multiple Measurements of Cognitive Function

WALTHAM, Mass., 2017-01-20 14:30 CET (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 announced the results of additional data analyses related to cognitive function from its 12-week, randomized, double-blind, placebo-controlled Phase IIb clinical trial of MIN-101 as monotherapy in patients with negative symptoms of schizophrenia. Data from this trial were reported in May 2016, and data from the 24-week open-label extension period of this trial were reported in October 2016.

“Cognitive impairment is a core feature of schizophrenia, affects up to 75 percent of the patient population and is a predictor of poor quality of life and functional status in patients with this disease,” said Dr. Remy Luthringer, president and chief executive officer of Minerva. “We have recently completed additional analyses from our Phase IIb trial with MIN-101 that show significant improvements in several sub-tests of cognitive functioning, including motor tests and verbal fluency in patients with schizophrenia. Deficits in these capabilities are associated with poor interpersonal and real-world functioning for these patients. We believe these latest findings hold promise for further clinical research in the improvement of cognitive function and drug development in schizophrenia.”

Cognitive function in this trial was evaluated using the Brief Assessment of Cognition in Schizophrenia (BACS) scale. This scale was developed specifically to assess cognitive impairment in patients with schizophrenia. Key data findings include the following:

P-value Effect size
32mg 64mg 32mg 64mg
- Motor Function: Token Motor Task 0.0306 0.0493 0.42 0.38
- Motor Function: Symbol Coding Task 0.6310 0.0781 0.09 0.33
- Verbal Fluency: Semantic Fluency 0.0299 0.1838 0.42 0.25
- Verbal Fluency: Letter Fluency 0.0328 0.0878 0.41 0.32
- Total Verbal Fluency 0.0076 0.0554 0.51 0.36
- Verbal Memory 0.1544 0.3158 0.27 0.19
- Executive Function: Tower of London 0.3988 0.1952 0.16 0.25
BACS cognition assessment (Composite T Score) 0.2737 0.8253 0.21 -0.04

Top line results previously announced from the double-blind, placebo-controlled 12-week core phase of the Phase IIb trial with MIN-101 showed that it met its primary endpoint of statistically significant improvement in negative symptoms as measured by the PANSS pentagonal structure model (PSM) and also showed statistically significant benefit in multiple secondary endpoints that included general psychopathology. Data from the extension phase of this trial showed continuous improvement in negative symptoms over a nine month period.

About MIN-101

MIN-101 is a drug candidate with equipotent affinities for sigma2 and 5‑hydroxytryptamine-2A (5-HT2A) and lower affinity at α1-adrenergic receptors. MIN-101 has no direct dopaminergic post-synaptic blocking effects, known to be involved in some side effects like extrapyramidal symptoms, sedation, prolactin increases and weight gain.

About Schizophrenia

As described by the National Institute of Mental Health, schizophrenia is a chronic and severe disorder that affects how a person thinks, feels and acts1. In 2015 approximately 3.2 million people suffered from schizophrenia in the U.S., Japan and the five major European markets. Schizophrenic patients suffer from positive, negative and cognitive symptoms. Negative symptoms are disruptions to normal emotions and behaviors that may signal social withdrawal. Patients may be socially inhibited, lack the ability to begin and sustain planned activities, or speak little even when forced to interact. Negative symptoms account for a substantial portion of the morbidity associated with schizophrenia2. They persist chronically throughout an individual patient’s lifetime and increase with severity over time. Similar to negative symptoms, cognitive symptoms may be difficult to recognize and often are detected only when specific testing is performed. Cognitive symptoms include: poor “executive functioning,” or the ability to understand information and use it to make decisions; trouble focusing or paying attention; problems with “working memory,” or the ability to use information immediately after learning it. Poor cognition is related to worse employment and social outcomes for patients with schizophrenia.
