177Lu-PSMA (177Lu-PNT2002) in PSMA-Positive Adenoid Cystic Carcinoma

Summary

This is a single arm trial with one Cohort for people with recurrent or metastatic adenoid cystic carcinoma that cannot be treated with surgery. 10 participants will be enrolled in Cohort 1 at Johns Hopkins and will undergo DCFPyL PET/CT and 177Lu-PSMA dosimetry imaging only (single tracer dose). A feasibility analysis of dosimetry will be performed after meeting the accrual goal of Cohort 1 to determine if the study will proceed into Cohort 2. If Cohort 2 proceeds, based on the dosimetry analysis, the major requirements of the study are to undergo treatment with 177Lu-PNT2002, have bloodwork, physical exams, and imaging done at study-specific time points, and to answer questionnaires. Patients will be in the study for about two years after enrolling.
