About

The main aim of this clinical trial is to assess the safety of FT1 in participants aged 18 to 45 years. The main questions it aims to answer are:

• Is FT1 safe in healthy adults? Researchers will compare FT1 to a placebo (a look-alike substance that contains no drug) to see if FT1 is safe and active in human.

Participants will

• Receive one subcutaneous injection or multiple injections of FT1 or placebo according to weight.
• Visit the clinic for assessment.

Full description

This study is a first-in-human study, which is a single-center, randomized, placebo-controlled, double-blind, dose escalation clinical study, aiming to evaluate the safety, tolerability, pharmacokinetics and immunogenicity of FT1 in healthy adult volunteers.

The trial is divided into 2 parts, single-dose part and multiple-dose part. In multiple-dose part, participants will receive once weekly subcutaneous injection of FT1 for 3 weeks.

Enrollment: 76 estimated patients

Sex: All

Ages: 18 to 45 years old
