Experimental ALS Drug Shows Unprecedented Recovery in some Patients
- Researchers at Columbia University announced on May 23, 2025, that the experimental drug ulefnersen shows promise for treating a rare aggressive form of ALS caused by FUS gene mutations.
- The development began six years ago when neurologist Neil Shneider first tested ulefnersen in Iowa patient Jaci Hermstad under the FDA's expanded access program amid no expected clinical improvement.
- A case series of 12 patients treated globally demonstrated that two patients had remarkable recoveries, including restored walking and breathing abilities, while others experienced slowed disease progression with no serious adverse events.
- After six months on ulefnersen, patients showed up to an 83% decrease in neurofilament light, a nerve damage biomarker, and Shneider noted that early intervention can reverse some functional losses.
- The ongoing global clinical trial aims to confirm these findings and could lead to ulefnersen's approval, representing a precision medicine breakthrough for young patients with FUS-ALS.

Experimental drug may benefit some patients with rare form of ALS
When Columbia neurologist and scientist Neil Shneider speaks to his ALS patients who volunteer for experimental therapies, he's unwaveringly honest. "Patients always ask me, 'What can I hope to get out of this?"' Shneider says. "And I always say, in most clinical trials, our hope is that we can slow the disease or maybe even halt progression."
Experimental drug 'Ulefnersen' offers unprecedented hope for rare form of ALS
An experimental drug known as ulefnersen has shown remarkable efficacy in treating a rare, aggressive form of ALS. Some patients experienced unprecedented functional recovery, offering new hope in a previously devastating diagnosis In a surprising and deeply motivating turn for the ALS research community and patients, an experimental drug has shown remarkable efficacy in treating a rare, aggressive form of Amyotrophic Lateral Sclerosis (ALS) cau…
