Brief summary: A Phase I, Randomized, Double-Blind, Placebo-Controlled, First-in-human, Single-Ascending-Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of retro enversio (RT) thymopentin in Healthy Adult Participants and Patients with Amyotrophic Lateral Sclerosis (ALS)

Detailed description: This is a first-in-human, randomized, double-blind, placebo-controlled, single-ascending-dose (SAD) study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of retro enversio thymopentin (FC-12738) in healthy adult participants and patients with ALS. The clinical trial will be conducted in two parts, initially a SAD study in 3-sequential cohorts of healthy adult participants (PartA), and then follows another SAD study in 4-6-sequential cohorts of patients with ALS (Part B). Dose escalation in the SAD cohorts will be determined after having reviewed of the interim safety data as well as all available PK and/or PD data from the preceding dose level(s).
