Enrollment Complete for DNL343 Trial in HEALEY ALS Study

Denali Therapeutics, a firm dedicated to developing a range of therapeutics for neurodegenerative and lysosomal storage diseases, has made significant progress in its clinical trials. The company has reported that the Phase 2/3 HEALEY ALS Platform Trial, which is evaluating Denali’s DNL343, has completed its enrollment for Regimen G. DNL343 is an innovative ALS treatment that targets eIF2B, a key component of the integrated stress response (ISR), which is implicated in ALS due to its overactivity leading to neuronal damage.

The HEALEY ALS Platform Trial is a collaborative initiative aimed at accelerating the development of potential ALS treatments by evaluating multiple therapies concurrently. The trial is conducted by the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital in conjunction with the Northeast ALS Consortium. The platform has been instrumental in advancing the research and development of ALS treatments.

Denali’s DNL343 has shown promise in preclinical studies where it was observed to dissolve stress granules that contain TDP-43, a protein associated with ALS, and reduce biomarkers of the ISR. The drug’s safety, pharmacokinetics, and pharmacodynamics have been assessed in Phase 1 and Phase 1b studies, demonstrating good tolerance and significant penetration into cerebrospinal fluid. The therapy is taken orally once a day.

The completion of enrollment for Regimen G is a pivotal advancement, and the trial's investigators, including principal investigator Merit Cudkowicz, express gratitude for the support from the ALS community and are eager to share the forthcoming results. Denali’s Chief Medical Officer, Carole Ho, also acknowledges the milestone and the collaborative efforts with the ALS community to enhance scientific understanding and develop effective treatments for ALS patients.

Denali Therapeutics is committed to rigorously pursuing new treatments by focusing on genetically validated targets and ensuring delivery across the blood-brain barrier. The company is based in South San Francisco and continues to work towards its mission of developing transformative therapies for severe neurological and lysosomal storage disorders.

It is important to note that DNL343 is still under investigation and has not yet been approved for commercial use by any regulatory authority. The journey towards developing effective treatments for ALS is complex and involves overcoming numerous scientific and clinical challenges. However, the dedication and collaboration evident in the HEALEY ALS Platform Trial offer hope for the advancement of ALS therapeutics.
