At a recent meeting on “Research priorities for preventing and treating Alzheimer’s disease and related dementias” (ADRD), convened by the National Academies, one consensus priority on ADRD research was that there needs to be more of it at every stage. Several speakers presented stark numbers on the relative volume of research in cancer and neurodegeneration. Research output, measured in peer-reviewed papers, for dementia is estimated to be around 10,000 papers annually, compared to 150,000 for cancer, while AD clinical trials are also few and far between compared to cancer trials. This final installment of BioWorld’s series on Alzheimer’s explores some of the reasons for this discrepancy along with the latest advances and ongoing efforts to accelerate research and drug development in the field.
Less than a month after disclosing that its confirmatory phase III trial of Relyvrio (sodium phenylbutyrate plus taurursodiol) fell short of its endpoint, Amylyx Pharmaceuticals Inc. is withdrawing the amyotrophic lateral sclerosis (ALS) drug from the market.
Building D&D Pharmatech Inc. has been a rollercoaster ride, according to CEO Seulki Lee. The U.S. and Korea-based biotech is on another ascent, having scored U.S. FDA fast track designation for its metabolic dysfunction-associated steatohepatitis (MASH) drug, ahead of its third attempt at a public listing.
Ironically, the first person to be diagnosed with what is now Alzheimer’s disease was missing its major risk factor. When she first began showing symptoms of dementia in 1901, Auguste Deter was not particularly old. Despite Deter’s case, aging is the largest risk factor for developing Alzheimer’s, by a large margin. But “geroscience has not been translated into drugs for Alzheimer’s disease,” Howard Fillit, Alzheimer’s Drug Discovery Foundation co-founder and chief scientific officer, told BioWorld. “We’re just starting to see that cross-fertilization now.”
Neuron23 Inc. has synthesized leucine-rich repeat kinase 2 (LRRK2; dardarin) inhibitors reported to be useful for the treatment of cancer, neurodegeneration and Parkinson’s disease.
Discovery of novel Nav1.8 inhibitors capable of achieving high levels of target modulation at low oral doses for the potential treatment of pain was reported by Merck & Co. Inc.
After decades of trying and dozens of failed trials, amyloid targeting has paid off with the first disease-modifying agents reaching the market. But success does not mean slam dunk. Aduhelm (aducanumab, Biogen Inc.) was dogged by controversy throughout its brief tenure, and Biogen pulled the plug on it in early 2024. Leqembi (lecanemab, Biogen Inc.) has received full approval. In this second installment of a three-part series on Alzheimer’s, BioWorld looks at the nuanced view of amyloid’s role in the disease.
Addex Therapeutics has offloaded its portfolio of preclinical allosteric modulation drugs into Neurosterix, a new company that arrives on the scene with a $63 million series A round.
