Clinical Trial Summary

This is a Phase 1a, double-blind, randomized, placebo- controlled, SAD study to assess safety, tolerability, PK, and PD of TU7710 in warfarin treated healthy male participants.

Description:

The 40 subjects will be divided into 5 cohorts, and the subjects assigned to each cohort will be randomly assigned with 6 persons receiving TU7710 and 2 persons receiving a placebo for TU7710. Each cohort will proceed in sequence and the next cohort study will be decided by the Safety Monitoring Committee (SMC) . Subjects will be participated in the study after warfarin anti-coagulation to maintain the INR between 2.00 and 3.00 as a preventive measure for potential thrombosis prior to the IP administration.

Intervention

Drug:
• TU7710
In each dose level, 6 subjects will be assigned to TU7710. Anticipated escalating dose levels are 100mcg/kg, 200mcg/kg, 400mcg/kg, 800mcg/kg and the last dose will be decided after assessing cohort 1~4 PK, PD, safety, and exploratory efficacy data.
• Normal saline
Placebo of TU7710 at corresponding TU7710 dose level. In each dose level, 2 subjects will be assigned to placebo group.
