Novus Therapeutics Announces First Patient Enrolled in Phase 2a Clinical Trial of Anti-CD40L Antibody AT-1501 in Amyotrophic Lateral Sclerosis

IRVINE, Calif.–(BUSINESS WIRE)– Novus Therapeutics, Inc. (“Novus”) (NASDAQ: NVUS), a clinical stage biopharmaceutical company focused on developing life-changing, targeted medicines for patients undergoing organ or cellular transplantation, as well as those living with immunological diseases, today announced that the first subject has been enrolled in the Phase 2a clinical trial evaluating AT-1501, the Company’s lead product candidate, in adults with amyotrophic lateral sclerosis (ALS). AT-1501 blocks the activation of the CD40L pathway, which has been shown to improve muscle function, slow disease progression, and improve survival in a pre-clinical animal model of ALS. AT-1501 previously received orphan drug designation from the U.S. Food and Drug Administration for the treatment of ALS.

“Novus is committed to providing people living with ALS and their families with a therapeutic solution to treat this progressive and devastating disease as expeditiously as possible,” said Steven Perrin, Ph.D., President and Chief Scientific Officer of Novus. “We look forward to the safety and biomarker insights from this study and we anticipate top-line data from this important trial in 2022.”

“There is strong evidence that the reduction of peripheral neuroinflammation has the capacity to influence disease progression in ALS,” said Dr. Merit Cudkowicz, Director of the Sean M. Healey & AMG Center for ALS, and Chief of Neurology at Massachusetts General Hospital, Boston. “I am excited to see the clinical advancement of AT-1501, which targets a key signaling pathway in the generation of pro-inflammatory responses.”

The AT-1501 Phase 2a trial in ALS is a 12-week, open label, dose escalating, safety and biomarker study. The endpoints of the study are safety and tolerability, and changes in pro-inflammatory biomarkers as well as neurofilament light chain. Exploratory clinical endpoints will also be assessed.

“We are in urgent need of new therapies for people living with ALS,” said Dr. Michael Rivner, Charbonnier Professor of Neurology and Director of the ALS Clinic at Georgia Regents Medical Center, Augusta. “AT-1501 and the CD40/CD40L pathway represent a highly promising approach to treating this disease.”

Novus Therapeutics has completed a Phase 1a/1b single ascending dose trial in healthy volunteers and adults living with ALS. In that trial, AT-1501 was well tolerated at all doses tested and demonstrated a good safety profile. AT-1501 also demonstrated linear dose proportionality across the dose range and a half-life of up to 26 days.

About AT-1501

AT-1501 is a humanized IgG1 anti-CD40L antibody with high affinity for CD40L, a well-validated target with broad therapeutic potential. The CD40/CD40L pathway plays a central role in generating pro-inflammatory responses in autoimmune disease, allograft transplant rejection, and neuroinflammation. In a Phase 1 safety study of healthy volunteers and adults with ALS, AT-1501 was well tolerated at all doses tested.

The discovery and early development of AT-1501 for ALS received support from The ALS Therapy Development Institute, Augie’s Quest, The Muscular Dystrophy Association, The ALS Association, ALS One, ALS Finding a Cure, and The ALS Ice Bucket Challenge.
