Sosei Group Corp. is getting €25 million (US$27.3 million) up front in a global collaboration and option-to-license deal with Boehringer Ingelheim GmbH aimed at developing GPR52 agonists, a new target for schizophrenia designed to potentially address positive, negative and cognitive symptoms at the same time.

After a disappointment with the same product in another indication about two years ago, Sensorion SA met the primary endpoint in its proof-of-concept phase IIa trial with SENS-401 for residual hearing preservation after cochlear implant.

The third day of the AD/PD 2024 conference in Lisbon started with a plenary lecture given by Professor Howard Fillit entitled, “Translating the biology of aging into new therapeutics for Alzheimer’s disease.” Fillit, a recognized neuroscientist and geriatrician, and co-founder of the Alzheimer’s Drug Discovery Foundation (ADDF), pointed to the geroscience hypothesis which postulates that targeting aging processes may result in preventive and therapeutic options for diseases of old age, including Alzheimer’s disease (AD).

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.

On March 4, 2024, several groups of scientists discussed the challenges of investigating the effects of HIV in the central nervous system (CNS) at the oral abstract session on neuropathogenesis of HIV held during the 31st Conference on Retroviruses and Opportunistic Infections (CROI), in Denver. A cure for HIV will require eliminating the virus in all its reservoirs, those tissues where HIV remains latent but retains the capacity for reactivation and replication. However, despite antiretroviral therapy (ART), the virus could continue to replicate continuously at a low level in some reservoirs, including the CNS.

Biovie Inc.’s double-barrelled blast of positive data with insulin sensitizer NE-3107 in Alzheimer’s disease (AD) and Parkinson’s disease (PD) launched shares (NASDAQ:BIVI) on a wild ride to close March 1 at $2.23, up 99 cents, or almost 80%, after trading as high as $3.31.

Pharmaust Ltd.’s monepantel met its primary safety endpoints and showed positive signals of potential efficacy in a phase I trial in patients with motor neuron disease (MND)/amyotrophic lateral sclerosis (ALS).
