SYN
Roluperidone (former developmental code names MIN-101, CYR-101, MT-210) is a 5-HT2A and σ2 receptor antagonist that is under development by Minerva Neurosciences for the treatment of schizophrenia.[1][2][3][4] One of its metabolites also has some affinity for the H1 receptor.[2] As of May 2018, the drug is in phase III clinical trials.[5]
Minerva Neurosciences (following the merger of Cyrenaic and Sonkei Pharmaceuticals ), under license from Mitsubishi Tanabe Pharma , is developing roluperidone (MIN-101, CYR-101, MT-210), a dual 5-HT2A /sigma 2 antagonist, as a modified-release formulation, for the potential oral treatment of schizophrenia. In December 2017, a phase III trial was initiated in patients with negative symptoms of schizophrenia. By March 2020, Minerva had filed an IND for apathy in dementia.
Schizophrenia is a complex, challenging, and heterogeneous psychiatric condition, affecting up to 0.7% of the world population according to the World Health Organization (WHO, 2006). Patients suffering with schizophrenia present with a range of symptoms, including: positive symptoms, such as delusions, hallucinations, thought disorders, and agitation; negative symptoms, such as mood flatness and lack of pleasure in daily life; cognitive symptoms, such as the decreased ability to understand information and make decisions, difficulty focusing, and decreased working memory function; and sleep disorders.
The etiology of schizophrenia is not fully understood. A major explanatory hypothesis for the pathophysiology of schizophrenia is the Dopamine (DA) hypothesis, which proposes that hyperactivity of DA transmission is responsible for expressed symptoms of the disorder. This hypothesis is based on the observation that drugs effective in treating schizophrenia share the common feature of blocking DA D2 receptors. However, these so-called typical antipsychotics are associated with a very high incidence of extrapyramidal symptoms (EPS). Furthermore, negative symptoms and cognitive impairment are considered relatively unresponsive to typical antipsychotics.
Most currently approved therapies for schizophrenia show efficacy primarily in the management of positive symptoms. An estimated 4.2 million people suffered from schizophrenia in 2012 in the United States and the five major European Union markets. Of those, an estimated 48% experienced predominantly negative symptoms and 80% suffered from cognitive impairment. In addition, about 50% of patients with schizophrenia experience sleep disorders, which can further exacerbate both positive and negative symptoms.
The introduction of the so-called atypical antipsychotics in the last decade represented a significant advance in the treatment of schizophrenia. Although these atypical antipsychotics differ widely in chemical structure and receptor-binding profiles, they share a characteristic of potent antagonism of the Serotonin (5-hydroxytryptamine) type 2 receptor (5-HT2A). A high 5-HT2A:D2 affinity ratio is thought to substantially reduce the liability for inducing EPS, compared with typical antipsychotics.
However, many patients are still treatment-noncompliant despite the advantage of atypical antipsychotics of tolerability. Although the risk of EPS is clearly lower with the atypical antipsychotics, the high doses required with some atypical antipsychotics are likely to result in an increased incidence of EPS and require concomitant medications such as antiparkinson drugs.
In addition to EPS, antipsychotic medications cause a broad spectrum of side effects including sedation, anticholinergic effects, prolactin elevation, orthostatic hypotension, weight gain, altered glucose metabolism, and QTc prolongation. These side effects can affect patients’ compliance with their treatment regimen. It should be noted that noncompliance with treatment regimen is a primary reason for relapse of the disease.
Although atypical antipsychotics offer advantages over typical antipsychotics in terms of symptom alleviation and side effect profile, these differences are generally modest. A certain population of patients still remains refractory to all currently available antipsychotics. Newer agents to address these issues continue to be sought.
