YQ23 Study in Patients With Critical Limb Ischaemia — YAN  

Critical Limb Ischemia Clinical Trial

Official title:
A Randomised, Double-Blind, Phase 1b/2a, Placebo-Controlled, Single Dose Study to Evaluate Safety, Tolerability, and Efficacy of YQ23 in Adult Patients With Critical Limb Ischaemia

Clinical Trial Summary

This is an early phase study to assess how safe and tolerable is the new study drug YQ23 and to compare the effectiveness of YQ23 against normal saline to treat critical limb ischaemia. The study also aims to understand how it affects the body and an optional substudy to assess how the human body takes up, breaks down, and clears the study drug. Eligible patients will be randomised to have a 2:1 chance to receive a single, intravenous, fixed dose of YQ23 or normal saline. Neither the patient nor the study site will know which treatment has been given. On the day of YQ23 administration, patients will be asked to stay in the study site for 3 days for safety observation. After discharge, they will be required to visit the study clinic for 3 times in a year to continue safety monitoring and assessment of treatment effect. Each subject's participation will be about 13 months after signing the informed consent.

Clinical Trial Description

This is a Phase 1b/2a, randomised, double-blind, placebo-controlled study to evaluate the safety, tolerability, and efficacy of an investigational product, YQ23, in patients with Critical Limb Ischaemia (CLI) during a follow-up period of 12 months. Fifty-one patients are planned for enrolment. The study consists of a screening period (up to 28 days), a double-blind treatment period, and a follow-up (12 months). Prior to randomisation, patients diagnosed with CLI will be stratified into: - Group of patients in whom revascularisation is not planned - Group of patients with planned revascularisation Within each group, patients will be randomised in a 2:1 ratio to receive single intravenous infusion of YQ23 120 mg/kg and normal saline, respectively at the study site. On the day of YQ23 administration, the patient will be admitted to the study site on Day 1 and will be discharged on Day 3. The total duration of participation in the study for each patient is approximately 13 months. Data on the study endpoints will be collected from baseline (pre-dose on Day 1), Day 3, Month 1, 6 and up to 12 months after study treatment infusion. ;
