5. Study Description

Brief Summary
Study NPT 2042 CL 101 is a first in human (FIH) study to evaluate the safety and pharmacokinetics (PK) of single and repeated ascending doses of NPT 2042 in healthy adult male and female subjects.
Detailed Description
The long-term goal of this program is to develop NPT 2042 an adjunct antiseizure treatment for patients with medically intractable epilepsy. Prior to evaluating efficacy in the intended patient population, safety and pharmacokinetics of NPT 2042 will be investigated.
