Testing FTX-101 in healthy male volunteers

A Randomized, Double-Blind, Placebo-Controlled, First-in-Human Study to Assess Safety, Tolerability, Pharmacokinetics, and Immunogenicity of Single and Multiple Ascending Doses of FTX-101 After Subcutaneous Injection of FTX-101 in Healthy Male Subjects

Phase 1 Interventional Find Therapeutics · NCT06617546

This study is testing a new drug called FTX-101 in healthy men to see how it affects the body and if it can help repair nerve damage.

What this trial studies

This Phase 1 clinical trial evaluates FTX-101, a synthetic peptide aimed at promoting myelin self-repair, in healthy male subjects. The study consists of two parts: a Single Ascending Dose (SAD) and a Multiple Ascending Dose (MAD) to assess the safety, tolerability, and pharmacokinetics of FTX-101. Participants will receive either the drug or a placebo, and the study will also investigate the immunogenic potential of FTX-101 and its effects on heart function. The goal is to understand how FTX-101 interacts with the body and its potential to aid in remyelination processes.

Who should consider this trial

Good fit: Ideal candidates are healthy adult males aged 18 to 59 with a BMI between 18.5 and 32.0.

Not a fit: Patients with significant health issues or those outside the specified age and BMI range may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatments that enhance myelin repair, potentially benefiting patients with demyelinating conditions.

How similar studies have performed: While this approach is novel, similar studies targeting remyelination have shown promise, indicating potential for success.
