A Phase 1 SAD/MAD dose escalation and expansion study to determine the safety and effectiveness of ²¹²Pb-DOTAM-GRPR1 in subjects with various GRPR-expressing Tumors
Full description
In this open-label, dose escalation and dose expansion single ascending dose (SAD) and multiple ascending dose (MAD) phase 1 study, adult subjects with recurrent or metastatic histologically confirmed GRPR-expressing tumors will be enrolled. In the dose escalation portion, a classic 3+3 design will be utilized. Dose escalation may proceed until the recommended MAD dose is determined. Up to four cohorts are expected to be enrolled. Once the recommended MAD dose is determined, no additional subjects will be enrolled in the SAD escalation portion and the MAD portion of the study will commence. Subjects will be treated with up to four cycles administered every 8 weeks.
