Alkermes plc’s placebo-controlled phase II study of alixorexton in treating narcolepsy type 2 (NT2) hit its dual primary endpoints, producing statistically significant and clinically meaningful improvement in wakefulness and excessive daytime sleepiness. Alkermes said alixorexton is the first oral orexin 2 receptor agonist that has shown efficacy in a large phase II clinical trial in those with NT2.
The U.S. FDA is turning the clock back more than 20 years to advance women’s health by narrowing the boxed warning on hormone replacement therapies (HRTs) for menopause. The agency announced at a Nov. 10 news conference that it’s working with companies to update their HRT labeling to remove references to risks of cardiovascular disease, breast cancer and probable dementia.
In Alzheimer’s disease, microglia act as a double-edged sword. They can either protect the brain or worsen the damage, depending on their activation state. Inflammatory activation harms healthy neurons. However, a study reveals that a special type of microglia expressing specific receptors and behaving like T cells may help mitigate this neurodegenerative condition.
Despite the formidable challenges for developing precision psychiatry, the approach is notching its first successes in the preclinical and even some clinical settings. Many individual studies as well as large projects like the Psychiatric Ratings using Intermediate Markers studies and the Psychiatric Biomarkers Network have been looking at multiple biomarker types, and have begun to identify predictors of specific symptoms, or disease progression.
Centessa Pharmaceuticals plc’s unremarkable third-quarter 2025 earnings report was greatly overshadowed by an early readout from its orexin receptor 2 (OX2R) agonist program in narcolepsy, particularly promising phase IIa data demonstrating ORX-750’s efficacy across a group of sleep disorders, though investors seek further data to differentiate Centessa’s program from potential competitors such as Takeda Pharmaceutical Co. Ltd.’s oveporexton and Alkermes plc’s alixorexton.
The U.S. FDA’s complete response letter (CRL) for Biohaven Ltd.’s lead asset, troriluzole, to treat spinocerebellar ataxia has prompted a wave of downstream changes at the company. There will be a roughly 60% cutback in annual R&D spending, not including personnel, as Biohaven focuses on three other late-stage clinical programs.
Psychiatry has struggled to enter the precision medicine era. But through a mix of innovations and bootstrapping, progress is coming to the field. Scientists are working on improving diagnoses by investigating potential biomarkers and collection methods.

Uniqure NV is regrouping after a surprise switcheroo by the havoc-beset U.S. FDA regarding phase I/II studies with AMT-130 vs. external control in Huntington’s disease (HD) – news of which pushed down the Lexington, Mass.-based firm’s shares (NASDAQ:QURE) Nov. 3 by $33.40, a loss of 49%, at the closing price of $34.29.
Neurodegeneration specialist Vesper Bio ApS has announced positive results from the phase Ib/II trial of its oral sortilin inhibitor VES-001 in frontotemporal dementia. The small study involved six participants who had not progressed to symptomatic disease but were carriers of mutations in the GRN gene that codes for progranulin, a growth factor that is essential for neuronal health.
