About this trial

This is a randomized, double-blind, placebo-controlled, single-ascending-dose Phase 1 study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of CM583 in healthy adult participants. Approximately 40 participants will be enrolled in five dose cohorts. Within each cohort, participants will be randomized in a 3:1 ratio to receive a single subcutaneous dose of CM583 or placebo.

Trial outcomes

Primary outcomes

1

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

TEAEs will be coded using Medical Dictionary for Regulatory Activities(MedDRA) and summarized by System Organ Class and Preferred Term. Serious, severe, treatment-related, fatal TEAEs and TEAEs leading to study withdrawal will also be summarized.

Time frame
Day 1 up to Day 169 or early discontinuation
2

Number of Participants With Clinically Significant Physical Examination Abnormalities

Physical examination findings judged to be clinically significant by the investigator will be summarized.

Time frame
Day 1 up to Day 169 or early discontinuation
3

Number of Participants With Clinically Significant Vital Sign Abnormalities

Vital sign assessments include systolic and diastolic blood pressure, pulse rate, respiratory rate, and body temperature. Clinically significant postbaseline abnormalities will be summarized.

Time frame
Day 1 up to Day 169 or early discontinuation
4

Change From Baseline in Heart Rate, PR Interval, QRS Duration, QT Interval, QTcF Measured by 12-Lead Electrocardiogram

Heart Rate, PR Interval, QRS Duration, QT Interval, QTcF (calculated as QT/RR\^0.33) will be measured using a 12-lead electrocardiogram.

Time frame
Day 1 up to Day 169 or early discontinuation
