What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 80 participants in total. It began in 2026-01-08 with a primary completion date of 2027-01-31.

Brief Summary

This study is part of the HEAL Initiative supported by the NIH. The purpose of this study is to learn how safe the study drug, SBS-147, is and how people's bodies respond to and process it. Researchers will also look for any side effects that may occur when taking SBS-147. Some participants will receive SBS-147, and others will receive a placebo, which looks the same but does not contain any medicine. This helps researchers fairly compare results. The study includes two parts: Single-Dose Group, where Participants receive SBS-147 or placebo one time. Multiple-Dose Group, where Participants receive SBS-147 or placebo once or twice daily for 7 days.
