Study of Single and Multiple Oral Doses of SCB0020160 in Healthy Adult Male Subjects

June 26, 2026 updated by: SCBIO Inc.

A First-in-Human, Double-blind, Placebo-controlled, Single and Multiple Ascending Dose, Phase 1 Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Food Effect of SCB0020160 After Oral Administration in Healthy Adult Male Subjects

This study aims to evaluate the safety, tolerability, pharmacokinetics, and food effect of a new investigational medicine called SCB0020160 in healthy adult men. This is the first time SCB0020160 will be administered to humans.

Healthy adult men aged 18 to 65 years who meet the study eligibility criteria.

Study details

Participants will be randomly assigned to receive either SCB0020160 or placebo. The study includes single-dose and multiple-dose treatment periods, as well as an assessment of the effect of food on the absorption of SCB0020160.

Participants will undergo safety assessments including physical examinations, vital signs, ECGs, blood and urine tests, and monitoring of adverse events. The study will also assess how SCB0020160 is processed by the body.

There is no direct health benefit expected from participation. The results may help determine safe dose levels and support future clinical development of SCB0020160.

Detailed Description

This study evaluates the safety, tolerability, and pharmacokinetics of SCB0020160 or placebo following single and multiple oral doses in healthy adult male subjects. A total of 74 subjects were planned, including 64 target subjects (8 per dose group) and 10 substitute subjects. The study may be completed without enrolling substitute subjects if all 64 target subjects complete the study.
