What this trial studies

This is a first-in-human, phase 1 clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of YH35995, a potential treatment for neurological symptoms associated with Gaucher Disease type 3. The study consists of two parts: a single ascending dose (SAD) administered to healthy male participants, followed by a multiple ascending dose (MAD) phase. Participants will receive either YH35995 or a placebo in a randomized, double-blind manner to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adult males aged 19 to 45 who meet specific weight and BMI criteria.

Not a fit: Patients who are not male or fall outside the specified age range or health criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a new treatment option for patients suffering from Gaucher Disease type 3.

How similar studies have performed: While this is a first-in-human study, similar approaches in early-phase trials have shown promise in evaluating new treatments for rare diseases.
