Phase 1
Recruiting
Conditions
Hemophilia a
Hemophilia B
Blood Coagulation Disorders
Interventions
Drug: Normal saline
Registration Number
NCT06025552
Lead Sponsor
TiumBio Co., Ltd.
Brief 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.

Detailed 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.

Primary Outcome Measures
NameTimeMethod
Number and proportion of participants with adverse events30 days post-dose

Number and proportion of participants with adverse events/ adverse reaction /SAE overall and by treatment group

Number of subjects with significant abnormal laboratory values30 days post-dose

Mean with standard deviation, median, maximum, minimum results of laboratory values in each treatment group. The laboratory parameters that will be assessed are clinical chemistry, hematology and urinalysis.

ADA and Neutralizing antibody results30 days post-dose

Incidence of subjects with ADA and Nab positive results

Number of subjects with significant abnormal Electrocardiography (ECG) findings30 days post-dose

Mean with standard deviation, median, maximum, minimum results of ECG results in each treatment group. The ECG parameters that will be assessed are heart rate, PR interval, QRS interval, QT interval, and QTcF interval.

Number of subjects With Significant Abnormal vital sign findings30 days post-dose

Mean with standard deviation, median, maximum, minimum results of vital sign values in each treatment group. The vital signs that will be assessed are body temperature, pulse rate, respiratory rate, and systolic and diastolic blood pressure.

Pharmacokinetics assessment_Maximum concentration4 days post-dose

Maximum plasma VIIa activity level in each dose level

Pharmacokinetics assessment_AUC last4 days post-dose

Area under plasma activity-time curve after TU7710 single administration from time zero to last quantifiable concentration

Pharmacokinetics assessment_AUC inf4 days post-dose
