Lantheus Medical Imaging
This is an open-label, nonrandomized, multicenter study conducted in two sequential parts: an initial Phase 2 Dose Optimization Period followed by the Phase 3 Diagnostic Performance Period. After the optimal administered activity and imaging time window are selected in Phase 2, Phase 3 will enroll participants with recently diagnosed PCa who are at least high risk or have suspected metastatic disease and are eligible for radical prostatectomy with pelvic lymph node dissection (RP+PLND). Safety assessments throughout the study will include monitoring of adverse events, vital signs, ECGs, and clinical laboratory parameters. Participants will be enrolled sequentially in a nonrandomized manner, with competitive enrollment across study sites.
Phase 2 Dose Optimization Period During the Phase 2 period, participants will receive 5 (±1) mCi (148 to 222 MBq) of \[68Ga\]-LNTH-2401 for PET/CT imaging with the primary objectives of determining the optimal administered activity, imaging parameters and tissue dosimetry. Up to 12 participants with GRPR-positive lesion(s) will undergo serial PET/CT scans at multiple time points during the first imaging visit to assess dosimetry and biodistribution. Data from 6 eligible participants with GRPR-positive lesion(s) will be used to determine the optimal administered activity and imaging time window…
