Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is an open label, phase I/II, multi-center study in adult participants with metastatic hormone sensitive prostate cancer (mHSPC) and with metastatic castration resistant prostate cancer (mCRPC) who have received prior anti-cancer treatment and have a positive 68Ga-PSMA-11 PET scan. The purpose of this study is to learn if the study drug, \[225Ac\]Ac-PSMA-R2, is safe and tolerable, and has anti-tumor activity in treated patients.

Inclusion Criteria	Exclusion Criteria
* Evidence of PSMA-positive disease by 68Ga-PSMA-11 PET/CT and eligible as determined by central reading * Documented progressive mCRPC or mHSPC * Adequate organ function * Prior orchiectomy or ongoing ADT and should have received prior 177Lu-PSMA-RLT (Group1 dose escalation \& expansion) or never received 177Lu-PSMA-RLT (Group 2 and Group 3 dose escalation \& expansion).	* Any other investigational agents within 28 days of the anticipated C1D1 of 225Ac-PSMA-R2 therapy * Any systemic anti-cancer therapy within 28 days of the anticipated C1D1 of 225Ac-PSMA-R2 therapy * Uncontrolled pain or incompatibility that may result in participant's lack of ability to comply with imaging procedures * History of CNS metastases and symptomatic cord compression, or clinical or radiologic findings indicative of impending cord compression * History of myocardial infarction, angina pectoris, or coronary artery bypass graft within 6 months prior to ICF signature and/or clinically active significant cardiac disease * Diagnosis of other malignancies in the past three years expected to alter life expectancy or may interfere with disease assessment
