A molecule containing radioactive fluorine was used with a PET scan to show that LY3372689 binds in the human brain.[2]
Eli Lilly and Company is recruiting subjects for a clinical trial.[3] Some hospitals in Australia: St Vincent's Hospital, Sydney Hornsby Ku-Ring-Gai Hospital, The Prince Charles Hospital, The Queen Elizabeth Hospital, Adelaide, Box Hill Hospital, and Delmont Private Hospital are involved.[4] Results of the trial were expected by June 2024.[5] Primary completion of the study occurred on 9th July 2024, with full completion expected in August 2024. In an investor call, it was disclosed that LY3372689 missed the primary endpoint of improvement on the Integrated Alzheimer's Disease Rating Scale. The detailed results of this study are expected to be disclosed at a conference in late 2024.[6]
Chemical
editThe molecule contains three rings: thiazole, piperidine and oxadiazole. Other functional groups included are an ether, acetamide, and a fluoride.[7]
