It has also approved an accompanying new indication for Locametz® (kit for the preparation of gallium Ga 68 gozetotide injection), an imaging agent also made by Novartis and first FDA approved in 2020.

    • Pluvicto: 7.4 GBq (200 mCi) once every six weeks, administered via intravenous injection or infusion, for up to six doses or until disease progression or unacceptable toxicity occur.
    • Locametz: 111 MBq to 259 MBq (3 mCi to 7 mCi) radioactivity, administered as a slow intravenous injection.
