TAUVID

After intravenous administration of TAUVID, flortaucipir F 18 was distributed throughout the body with less than 10% of the injected F 18 radioactivity present in the blood by 5 minutes following administration, and less than 5% present in the blood by 10 minutes after administration. The residual F 18 in circulation during the 80-minute to 100-minute imaging window was approximately 28% to 34% parent, with the remainder being metabolites. Clearance occurs primarily by hepatobiliary and renal ex...

The performance of TAUVID imaging to estimate the density and distribution of aggregated tau neurofibrillary tangles (NFTs) was evaluated in two clinical studies:

Study 1(NCT02516046) and

Study 2(NCT03901092). In each study, TAUVID imaging was interpreted by 5 independent readers who were blinded to clinical information. Readers interpreted TAUVID imaging as positive or negative [see Dosage and Administration ( 2.6 )] . Study 1 enrolled 156 terminally ill patients who agreed to undergo TAUVID imaging and to participate in a postmortem brain donation program. In 64 of these patients, reader i...

Most common adverse reactions (frequency ≥ 0.5%) were headache, injection site pain, and increased blood pressure.

Risk of Misdiagnosis in Patients Evaluated for Alzheimer's disease : Consider additional evaluation to confirm the absence of AD pathology in patients with a negative TAUVID scan. ( 2.6 , 5.1 ) Risk of Chronic Traumatic Encephalopathy Misdiagnosis : The safety and effectiveness of TAUVID have not been established for patients being evaluated for CTE. ( 1 , 5.2 ) Radiation Risk : Ensure safe drug handling to protect patients and health care workers from unintentional radiation exposure. ( 2.1 , 5...
