Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to determine the safety and tolerability of multiple doses of QRL-201 in people living with ALS

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This first-in-human, Phase 1 study will evaluate the safety, tolerability, and pharmacokinetics (PK) of QRL-201 administered intrathecal (IT) to participants with Amyotrophic Lateral Sclerosis. Two dose escalation cohorts of 8 participants each, followed by an additional 48 participants, receiving the study drug in a 6:2 ratio of QRL-201 to placebo.
