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 88 participants in total. It began in 2026-03-05 with a primary completion date of 2026-11.

Brief Summary

This study is a first-in-human (FIH) trial of CMS-D017 conducted in healthy Chinese adult participants, consisting of two parts: Part 1-a single ascending dose (SAD) study (referred to as Part 1 SAD), and Part 2-a multiple ascending dose (MAD) study (referred to as Part 2 MAD). The study aims to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) characteristics of CMS-D017 capsules following single and multiple oral administrations in healthy Chinese adult participants. Both parts of the study are designed as randomized, double-blind, placebo-controlled, sequential cohort trials. Part 1 SAD plans to include 6 dose cohorts, with 8 participants per cohort (6 receiving CMS-D017 and 2 receiving placebo), for a total of 48 participants. Part 2 MAD plans to include 4 dose cohorts, with 10 participants per cohort (8 receiving CMS-D017 and 2 receiving placebo), for a total of 40 participants.
