Brief Summary:
This is a multicenter, randomized, double-blind, placebo-controlled, dose-escalation trial. The goal of this clinical trial is to evaluate the safety and preliminary efficacy of nasal drop exosomes derived from human umbilical cord blood mesenchymal stem cells (hUC-MSC-sEV-001) in amyotrophic lateral sclerosis.
Detailed Description:
This is a multicenter, randomized, double-blind, placebo-controlled, dose-escalation trial. The study will consist of two parts: Part 1 will be a dose-escalation study, and Part 2 will be an expanded safety study based on the findings from Part 1.
A traditional 3+3 dose-escalation design will be implemented in Part 1. Cohort 1 will receive low-dose; Cohort 2 will receive middle-dose; and Cohort 3 will receive high-dose. (Cohort 1 to Cohort 3 will receive a dose of 1 mL per nostril, administered once daily, twice a week, for a total of two weeks.) If no dose-limiting toxicities (DLTs) are observed for 2 weeks after the administration of the first nasal drop, a new cohort will be enrolled at the next planned dose level. If DLTs are observed in one participant in the cohort, an additional three participants will be treated at the same dose level. Dose escalation will be stopped if DLTs are observed in more than 33% of the participants.
In Part 2, 20 subjects will be randomized in a 1:1 ratio \[exosome (n=10) or exosome placebo (n=10)\]. The dose level will be determined by the primary researcher based on the findings from Part 1.
