Australia’s Therapeutic Goods Administration (TGA) has once again decided against approving Eisai Australia Pty Ltd.’s amyloid beta binder, Leqembi (lecanemab), for treating patients with mild cognitive impairment due to Alzheimer's disease and mild Alzheimer's dementia.
Zhongzhi Pharmaceutical Holdings Ltd. made a $3 million investment in a series A financing round of stem cell therapy developer Gabaeron Inc. Dec. 21, expected to help propel Gabaeron’s preclinical Alzheimer’s disease (AD) candidate into phase I testing.

The EMA has changed its mind about an earlier decision that the risks of Leqembi (lecanemab) outweigh the benefits and is now recommending the Alzheimer’s disease drug is approved for a subgroup of patients. That follows an appeal by Eisai Co. Ltd. and a re-examination of the data, after details relating to 274 patients with two copies of the ApoE4 gene were removed from the file.
Reducing microglial activity in the presence of apolipoprotein E4 (APOE4) has uncovered a mechanism associated with the deposition of misfolded amyloid and tau in a novel mouse model of Alzheimer’s disease. By transplanting human neurons into the mouse brain and eliminating the mouse microglia, scientists at the Gladstone Institutes in San Francisco observed that amyloid and tau deposition was reduced. These results support therapeutic strategies that target APOE4 and microglia.
The E4 variant of the APO gene, the R47H variant of the TREM2 gene, and female sex are three of the strongest risk factors for the development of Alzheimer’s disease (AD). By combining all three of them in a mouse model of tauopathy, researchers at Weill Cornell Medical School have identified microglial inflammation and senescence as processes that occurred more strongly in female mice as tauopathy developed.
Seoul, South Korea-based Adel Inc. raised ₩17 billion (US$12.39 million) in bridge financing to advance its pipeline of Alzheimer’s disease therapies, including its tau antibody-based ADEL-Y01 candidate, currently in a U.S.-based phase I study.

Alzheon Inc. has raised $100 million in a series E financing round to push its oral drug candidate for early Alzheimer’s disease (AD), ALZ-801 (valiltramiprosate), through a late-stage, Apolloe4 study.
Based on its analysis of a large cohort of individuals homozygous for the ε4 variant of apolipoprotein E (APOE4), a multinational team of researchers is arguing that homozygosity for APOE4 should be considered a genetic form of Alzheimer’s disease. However, not everyone agrees that the findings warrant reclassifying APOE from risk factor to causal gene. Currently, APOE4 is classified as the strongest risk factor for developing AD. Another variant, the APOE2 variant, is protective, while APOE3 is neutral.
