About this study

Official title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of Single Ascending Doses of CM583 in Healthy Adult Participants

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 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.

    Measured: 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.

    Measured: 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.

    Measured: Day 1 up to Day 169 or early discontinuation

  5. Number of Participants With Clinically Significant Laboratory Test Abnormalities

    Laboratory assessments include hematology, blood chemistry, coagulation, lipid tests, and urinalysis. Clinically significant postbaseline abnormalities will be summarized.

    Measured: Day 1 up to Day 169 or early discontinuation

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CM583 in people with Healthy, run by Keymed Biosciences Co.Ltd at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 16 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Qian Jia (028-88610620, clinicaltrial@keymedbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) (time frame: Day 1 up to Day 169 or early discontinuation). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Sep 2026.
