Drugs in Clinical Pipeline: SUVN-502 | 5-HT6 receptor antagonist | Treatment for Alzheimer's Disease

SUVN- 502 is a novel, potent, and selective 5-HT6 receptor antagonist with Ki of 1.71 nM and exhibited antagonist like inhibition with EC50 of 0.103 mM. SUVN-502 is effective in animal models of cognition. In microdialysis studies, SUVN-502 enhanced brain acetylcholine and glutamate levels in rat ventral hippocampus and frontal cortex. SUVN-502 has completed all regulatory safety and toxicity studies.

5-HT6 receptor a member of serotonin family predominates in brain regions associated with cognition and behavior. The blockade of 5-HT6 receptors leads to an improvement of cognitive performance in a wide variety of learning and memory paradigms.

The tolerability of SUVN-502 upto highest dose administered was considered as very good. No serious adverse events occurred. No clinically significant changes or study medication related abnormalities were observed with respect to ECG’s and laboratory evaluations. It is in Phase I/II trials and being developed as a treatment for Alzheimer's disease (AD).
