Phase 1, Randomized, Double-blind, Placebo-controlled, Single Ascending Dose Study to Assess the Safety, Tolerability, and Pharmacokinetics of JST-018 in Healthy Adults
Just-Evotec Biologics
Summary
The goal of this clinical trial is to learn if a single dose of the study drug, JST-018, is safe and tolerable when administered by injection into the arm or thigh muscle of healthy men and women aged 18 to 55. The main questions it aims to answer are: * Is a single administration of JST-018 safe? * What is the concentration of the JST-018 in the blood over time? * Do antibodies to JST-018 develop following a dose of JST-018? Researchers will compare JST-018 to Placebo to see if there are any differences in the safety and tolerability of a single dose at different dose levels. Participants will be confined to the clinic for the first 3 days. They will receive an injection on the second day, and then return for 9 more visits over the period of 1 year for: * Physical exam with vital signs * Electro-cardiogram (ECG) * Bood collection for clinical labs and research samples * Urine sample * Assessment of potential adverse effects and medications taken
Description
This is a Phase 1, first-in-human (FIH), randomized, double-blind, placebo-controlled, single ascending dose (SAD) study to assess the safety, tolerability, and PK of a single dose of JST-018 administered IM to healthy participants. The study will be comprised of a minimum of 3 cohorts (Cohorts A, B, and C, with 12 participants per cohort), each evaluating a single dose of JST-018 administered IM. In each cohort, 2 sentinel participants will be randomized 1:1 such that one participant receives JST-018 and 1 participant receives placebo. Following a favorable blinded safety review committee (S…
