Treatment of animal models of Alzheimer's disease with extracellular vesicles or exosomes and involvement of microRNAs. (PubMed, Neural Regen Res) - "Conventional treatments focus on symptom management through acetylcholinesterase inhibitors, such as donepezil, galantamine, and rivastigmine, and the N-methyl-D-aspartate receptor antagonist memantine. However, the past few years have seen the approval of newer agents such as sodium oligomannate, aducanumab, and lecanemab, which show some promise in slowing disease progression...Loading extracellular vesicles and exosomes with microRNA mimics (e.g., miR-22, -29b, -124, -132, -138-5p, -342-5p, -711, and -7670-3p) or antagomirs (e.g., miR-206-antagomir) improved outcomes in animal models of Alzheimer's disease. Supporting results were found in the in vitro cell studies reviewed."

Study on the improvement of cognitive deficits in APP/PS1 mice by danggui shaoyao san and its disassembled prescriptions through modulation of the gut microbiota. (PubMed, Front Microbiol) - "Forty APP/PS1 and eight C57BL/6 mice were divided into six groups: DSS (6.4 g/kg/d), QDW (4.6 g/kg/d), DW (1.8 g/kg/d), GV971 (positive control, 40 mg/kg/d), model (saline), and control (saline)...Danggui Shaoyao San and its disassembled prescriptions ameliorate AD-related cognitive impairment and gut dysbiosis, enhance microbial diversity, and modulate metabolic pathways, supporting their therapeutic potential via gut-brain axis regulation. This study elucidates the multi-target mechanisms of DSS in AD treatment, advancing TCM rationalization for neurodegenerative disorders."

Chinese authorities did not renew a conditional approval of Green Valley Pharmaceuticals’ controversial Alzheimer’s disease drug sodium oligomannate, also known as GV-971... (Fierce Pharma) - "As part of its routine disclosure of regulatory activities on Aug. 12, China’s National Medical Products Administration (NMPA) put its responses to Green Valley’s applications to turn GV-971’s conditional nod into a full approval in a group marked 'notification delivery' but not the 'approval document delivery' list. This move suggests that the drug did not get approval....The exact reason for the rejection is unclear."

Chinese Firm Halts Production of Controversial Alzheimer’s Drug (Bloomberg) - "A Chinese company that developed the country’s first indigenous therapy for Alzheimer’s disease has suspended production and sales of the drug, casting doubts on the treatment’s future. The drug’s license has expired and its renewal is now in the final stages of a regulatory review, during which it must stop commercial production and sales, Green Valley Pharmaceutical Co. said in an emailed statement to Bloomberg News on Tuesday....Green Valley’s drug - a seaweed-derived compound known as sodium oligomannate, or GV-971 - was hailed as a major advance when China’s drug regulator gave it conditional approval in 2019....Local and international medical experts have since questioned how effective it really is in slowing or reversing the cognitive declines of Alzheimer’s patients given the relatively short duration of - and the inconsistent results shown in - its late-stage clinical trial in China."
