Clinical Trial Summary

The goal of this clinical trial is to learn about the safety and pharmacokinetics (PK, the amount of drug in the blood) of a new drug called CDI-988 in healthy volunteers.

The main questions it aims to answer are:

• Are there any side effects of the drug?

• What is the amount of drug that reaches the bloodstream? Participants will be assigned by chance to take either CDI-988 or placebo by mouth and have physical exams, electrocardiograms (ECGs), vital signs, and blood tests to look for any side effects.

Description:

CDI-988 is a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) 3-chymotrypsin-like (3CL) protease inhibitor for oral administration. This study is being conducted in 2 parts to examine the safety, tolerability, and PK of CDI-988 in healthy participants. Part 1 will entail escalating single doses in sequential cohorts and Part 2 will enroll escalating multiple-dose cohorts. Participants will be monitored for adverse events, vital signs, laboratory values, and electrocardiograms (ECGs).
