A Study to Investigate the Safety, Tolerability and Pharmacokinetics of SUVN-D4010 in Healthy Subjects

This is a single and multiple ascending dose study to assess the safety, tolerability and pharmacokinetics of SUVN-D4010 administered orally once a day to healthy male subjects. The study will be conducted under double blind conditions.

The primary objective is to evaluate the safety and tolerability of SUVN-D4010 following oral administration of single or multiple ascending doses and estimate the maximum tolerated dose of SUVN-D4010,if possible.

The secondary objectives are to evaluate the single and repeat dose plasma pharmacokinetics following oral administration of single and multiple ascending doses of SUVN-D4010 in healthy male subjects.
