Masupirdine (SUVN-502), a pure 5-HT6 receptor antagonist: Rationale for evaluation in patients with agitation in dementia of Alzheimer's type (WCC Halls A-C) - Nov 3, 2023 - Abstract #Neuroscience2023NEUROSCIENCE_7246; P2a, P3 In addition, masupirdine significantly modulated levels of dopamine and norepinephrine in brain at a dose of 10 mg/kg, s.c. The post hoc analysis of the Phase-2 study (NCT02580305) in patients with moderate AD suggested treatment with masupirdine at 50 mg and 100 mg significantly decreased the agitation/aggression score from Week 13 to Week 26 suggesting potential treatment effects of masupirdine on agitation/aggression symptoms. To explore the beneficial effects, masupirdine is currently being evaluated as a monotherapy in a global Phase-3 study for the potential treatment of agitation in participants with dementia of Alzheimer's type (NCT05397639).

Journal: A 2023 update on the advancements in the treatment of agitation in Alzheimer's disease. (Pubmed Central) - Mar 25, 2023 Clinical trials remain underway utilizing both novel and repurposed agents to address symptoms of agitation in AD. With increasing understanding of the neurobiological mechanisms that fuel the development of agitation in AD, the use of enhanced trial design and conduct, advanced statistical approaches, and accelerated pathways for regulatory approval, we are advancing closer to having safe and efficacious treatment options for agitation in AD.

[VIRTUAL] MASUPIRDINE (SUVN-502) IN COMBINATION WITH DONEPEZIL AND MEMANTINE - PATIENTS WITH MODERATE AD - MEMANTINE REGIMEN, CONCENTRATIONS AND TREATMENT DURATION (EXHIBITION HALL) - Jan 6, 2020 - Abstract #AATADPD2020AAT_ADPD_790; Results In the mITT population, 65.7% of subjects were on donepezil 10 mg+memantine 10 mg BID; 17.9% were on donepezil 10 mg daily+Namenda XR 28 mg daily; and 16.4% were on Namzaric – there is no significant differences in assignment across the three treatment arms. Conclusions The results of these exploratory subgroup analyses to assess potential differential effects of memantine regimen, memantine plasma concentrations and memantine treatment duration on outcome measures in this masupridine triple therapy trial will be presented.

Journal: SUVN-502, a novel, potent, pure, and orally active 5-HT6 receptor antagonist: pharmacological, behavioral, and neurochemical characterization. (Pubmed Central) - Aug 8, 2019 The beneficial effects of SUVN-502 on learning and memory might be mediated through the modulation of cholinergic and/or glutamatergic neurotransmission in relevant brain regions. In summary, behavioral, neurochemical, and electrophysiological outcomes indicate that SUVN-502 may augment the beneficial effects of donepezil and memantine combination.
