A first-quarter 2024 launch for Alzheimer’s drug donanemab appears to be off the table as Eli Lilly and Co. disclosed a last-minute decision by the U.S. FDA to convene an advisory committee to review data from the phase III Trailblazer-ALZ 2 trial.

Tweaks made to the design of the phase III trial called Phoenix (vs. the narrowly positive phase II Centaur study) with Amylyx Pharmaceuticals Inc.’s amyotrophic lateral sclerosis (ALS) drug Relyvrio (sodium phenylbutyrate plus taurursodiol) didn’t work. Now, the Cambridge, Mass.-based firm is facing possible withdrawal of the treatment from the U.S. and Canada, where it’s known as Albrioza. Shares of Amylyx (NASDAQ: AMLX) closed March 8 at $3.36, down $15.61, or 82.3%, after the firm disclosed top-line results from Phoenix, a global, 48-week, randomized, placebo-controlled phase III effort with Relyvrio, also known as AMX-0035.

Rehab Technologies Lab recently unveiled a new robotic exoskeleton, Twin, designed for lower limbs to allow patients with spinal cord injuries to walk independently. Although Twin is currently a prototype, the company will work towards getting CE mark to bring it to the market to help patients with physical impairments integrate back into social and work environments.

Vascular dementia accounts for the second most common cause of dementia after Alzheimer’s disease.

Satellos Bioscience Inc. recently presented preclinical data for the novel oral small-molecule AP2-associated protein kinase 1 (AAK1) inhibitor SAT-3247, being developed for the treatment of Duchenne muscular dystrophy and other muscle degenerative diseases, at the Muscular Dystrophy Association conference.

Since microglia play a critical role in resolving amyloid pathology and it has been previously demonstrated that microglia function can be induced by TREM2 activation, TREM2 agonism has been considered a promising novel therapeutic approach to delay or prevent the progression of Alzheimer’s disease.

Solid Biosciences Inc. has announced a nonexclusive worldwide license and collaboration agreement with Armatus Bio Inc. for the use of Solid’s proprietary capsid AAV-SLB101 for the development and commercialization of Armatus’ vectorized RNAi candidate to treat facioscapulohumeral muscular dystrophy (FSHD).

At the 2024 Alzheimer’s & Parkinson’s Diseases Conference this week, Michel Goedert from the MRC Laboratory of Molecular Biology in Cambridge gave the Donald L. Price Memorial Plenary Lecture entitled, “Cryo-EM structures of disease filaments from human brains.” Donald Price was particularly well-known for his work on plaques and tangles in nonhuman aged primate brains and for the development of several animal models of neurodegenerative diseases.
