Investigators at the Weizmann Institute of Science have identified changes in oligodendrocytes that were shared across multiple dementia types. The team reported its results in the June 27, 2022, online issue of Nature Neuroscience.

Alzheimer’s experts have suggested that future research may involve combination therapies after yet another trial failure involving a drug targeting amyloid – in this case Roche Holding AG’s crenezumab. Originally discovered by Swiss biotech AC Immune SA, of Lausanne, crenezumab failed to slow or prevent cognitive decline in people with a certain mutation that causes early onset in a closely watched trial.

Astrazeneca plc’s Alexion rare diseases unit has taken an option to buy all remaining equity in Caelum Biosciences Inc., adding a rare disease drug to its pipeline in a deal worth $500 million. At the center of the deal is CAEL-101, a potentially first-in-class monoclonal antibody designed to tackle the toxic amyloid deposits that build up in organs of people with the rare disease light chain amyloidosis.

Researchers at Curtin University in Perth, Australia, have discovered that leakage from blood into the brain of fat-carrying particles transporting toxic proteins are a possible cause of Alzheimer's disease.

Brain-wide genome editing via a single systemic dose of modified adeno-associated virus variants that cross the blood-brain barrier may represent a promising new approach for the development of disease-modifying treatments for familial Alzheimer's disease. This strategy could also be applicable to other central nervous system (CNS) disorders, according to a proof-of-concept (PoC) study led by researchers at The Hong Kong University of Science and Technology (HKUST).

In a deal that could be worth up to $565 million, Simcere Pharmaceutical Group Ltd. licensed in glutaminyl cyclase inhibitor varoglutamstat (PQ-912) and monoclonal N3pE-antibody PBD-C06, which target the neurotoxic amyloid species N3pE (pGlu-Abeta), from Vivoryon Therapeutics AG to develop and commercialize for Alzheimer’s disease in greater China.
