This study was the first-in human study of CT-P59. It was a Phase 1, randomized, double-blind, placebo-controlled, parallel group, single ascending dose study to evaluate the safety, tolerability and pharmacokinetics of CT-P59 in healthy subjects.
Single IV infusion over 90 minutes (±15 minutes) of CT-P59 in doses of 10 mg/kg, 20 mg/kg, 40 mg/kg and 80 mg/kg was safe and well-tolerated in healthy subjects and no new major safety concerns were identified.
Based on the pharmacokinetic analysis, CT-P59 was approximately dose proportional in terms of maximal and systemic exposure over the studied dose range of 10 mg/kg to 80 mg/kg and these active moieties will be largely out of the systemic circulation after 5 half-lives, i.e. approximately 95 days after administration.
