A month away from the PDUFA decision date for a Leqembi (lecanemab) subcutaneous autoinjector to be used for maintenance dosing for those with early Alzheimer’s disease, Eisai Co. Ltd. and Biogen Inc. presented clinical data at the Alzheimer's Association International Conference (AAIC) 2025 in Toronto, showing comparable efficacy and safety to the FDA-approved intravenous formulation.
Investigators at Yonsei University have reported findings from studies conducted to identify small molecules capable of disaggregating amyloid-β42 (Aβ42) aggregates, a hallmark of Alzheimer’s disease.
Dysregulation of cholinergic neurotransmission through muscarinic receptors, particularly the M1 and M4 subtypes, has been implicated in the pathophysiology of schizophrenia. Muscarinic M4 receptor agonists and positive allosteric modulators (PAMs) have demonstrated the ability to modulate the disrupted neural circuits associated with this disorder.
At the 2025 Alzheimer’s Association International Conference (AAIC), one of the bigger splashes was made by a cardiovascular drug. In a presentation on July 30, Newamsterdam Pharma Co. NV presented data showing that its cholesterol drug obicetrapib lowered levels of the Alzheimer’s Disease biomarker p-tau217.
Researchers from Insmed Inc. presented findings on INM-901, a novel synthetic cannabinoid analogue, demonstrating its effects in the 5xFAD mouse model of Alzheimer’s disease. Alzheimer’s disease is a progressive neurodegenerative disorder characterized by cognitive decline and sensorimotor impairments, with no available treatments that effectively halt disease progression.
We all look different to HIV, a virus that destroys the immune system. The defensive cells record every interaction with foreign agents, infections from viruses and bacteria, but also with mechanisms occurring within the body, such as microbiome metabolism, the effects of aging, or the development of diseases. At a preconference session at the 13th IAS Conference on HIV Science (IAS 2025), scientists explained the interactions of different microorganisms with HIV.
There is still no effective vaccine or cure for HIV. Scientists are considering options ranging from longer-term antiretroviral therapy (ART) that space out injections by several years to long-lasting pre-exposure prophylaxis (PrEP) that acts as a vaccine while immunization is achieved. What else can be done?
Graves disease (GD)-associated hyperthyroidism is an autoimmune disorder characterized by the presence of autoantibodies that stimulate the thyroid-stimulating hormone receptor (TSHR), leading to excessive production of thyroid hormones.
