June 20, 2022 updated by: Shanghai Henlius Biotech
A Randomized, Double-Blind, Placebo-Controlled, Dose Escalation Phase I Clinical Study to Evaluate Safety and Pharmacokinetics of HLX70 in Healthy Adult Volunteers
A single-center, randomized, double-blind, placebo-controlled, dose escalation, phase I clinical study to evaluate safety and pharmacokinetics of HLX70 in healthy adult volunteers
Study Overview
Detailed Description
A randomized, double-blind, single-dose by intravenous administration, placebo-controlled, dose escalation, first-in-human study is proposed to evaluate the safety, PK, and immunogenicity of HLX70 in healthy subjects.
We plan to enroll 8 subjects in each of the 3 dose cohorts at 3 mg/kg, 10 mg/kg, and 30 mg/kg, of which 2 receive intravenous injections of placebo and 6 receive intravenous injections of the investigational product (IP).
A total of 24 subjects will be enrolled.
