CM583: CM583 injection administered SC(Subcutaneous), once
Placebo: Placebo injection administered SC, once
Study summary
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.

Primary outcome measure(s)
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) — Day 1 up to Day 169 or early discontinuation 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.
Number of Participants With Clinically Significant Physical Examination Abnormalities — Day 1 up to Day 169 or early discontinuation Physical examination findings judged to be clinically significant by the investigator will be summarized.
Number of Participants With Clinically Significant Vital Sign Abnormalities — Day 1 up to Day 169 or early discontinuation Vital sign assessments include systolic and diastolic blood pressure, pulse rate, respiratory rate, and body temperature. Clinically significant postbaseline abnormalities will be summarized.
Change From Baseline in Heart Rate, PR Interval, QRS Duration, QT Interval, QTcF Measured by 12-Lead Electrocardiogram — Day 1 up to Day 169 or early discontinuation Heart Rate, PR Interval, QRS Duration, QT Interval, QTcF (calculated as QT/RR\^0.33) will be measured using a 12-lead electrocardiogram.
Number of Participants With Clinically Significant Laboratory Test Abnormalities — Day 1 up to Day 169 or early discontinuation Laboratory assessments include hematology, blood chemistry, coagulation, lipid tests, and urinalysis. Clinically significant postbaseline abnormalities will be summarized.
