Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: EARLY_PHASE1

Brief Summary

This study is a randomized, double-blind, placebo/positive control Phase Ia clinical trial evaluating the safety, tolerability, and pharmacokinetics of SIBP-A16 injection in healthy adults

Detailed Description

This study plans to set up 5 queues, with queues 1, 3, 4, and 5 each containing 20 participants in the experimental group and 4 participants in the placebo group. Queue 2 contains 20 participants in the experimental group, 20 participants in the positive control group, and 4 participants in the placebo group. The total number of participants included in the five queues is 140. SIBP-A16 injection and placebo will be administered in four different doses and two different ways of administration. The study adopted a sequential injection design. After completing a 14-day preliminary safety observation of drug administration in the previous group, the Safety Review Committee (SRC) will conduct a preliminary safety assessment. Once the SRC evaluation results are safe (not meeting the dose escalation termination criteria), the next group will be enrolled.
