Exploratory PK and Imaging Study of PSMA-Targeted Trillium Compounds and PTI-122 in Metastatic Prostate Cancer
Completed · Early Phase 1
Conditions studied: Prostate Cancer
In brief
Exploratory study in adult males with metastatic prostate cancer intended to characterize the pharmacokinetics and biodistribution of PSMA-Targeted \[In-111\]-Labeled Trillium Compounds with and without the cytoprotective agent PTI-122. Up to 36 eligible subjects will be enrolled. Additional subjects may be enrolled if there is insufficient data for evaluation, for example if the original study subjects do not complete required imaging studies for reasons unrelated to adverse events. Up to four PSMA-Targeted \[In-111\]-Labeled Trillium Compounds will be evaluated. Each compound will be evaluated first without the cytoprotective agent, PTI-122, then the \[In-111\]-labeled Trillium Compound may be co-administered with PTI-122.
