Evaluation Safety, Tolerability, and Pharmacokinetics of Single and Multiple Ascending Doses of 83-0060 in Healthy Volunteers

This is a Phase 1, double-blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, PK, PD of orally administered 83-0060 in Healthy Volunteers. The study will be conducted in 2 parts: a single ascending dose (SAD) part at up to 5 dose levels and a multiple ascending dose (MAD) part at up to 3 dose levels. Evaluation of dose levels will be conducted in a sequential fashion with lower dose levels evaluated first in the sequence.

• Adult males and females, 18 to 65 years of age (inclusive) at screening.

• Acute infections within 4 weeks prior to screening or current infection that requires systemically absorbed antibiotic, antifungal, antiparasitic or antiviral medications.
• Presence or history of any abnormality or illness, including gastrointestinal surgery, which in the opinion of the PI may affect absorption, distribution, metabolism or elimination of the study drug.
