Participant Flow

Participants were recruited by physician referral at academic medical centers in the United States and Canada. Of 28 sites activated, 23 sites (16 in the United States and 7 in Canada) enrolled at least 1 participant. The study was initiated on 30May2019. The first participant consented on 07Jun2019 and last participant consented on 10Jun2022.

A total of 177 participants were screened. Of 132 participants who underwent piflufolastat imaging, 123 met the inclusion criterion of PSMA avidity.

Participants received up to 4 (8-week) cycles of I-131-1095: 100 mCi for the first dose. Subsequent dose(s) were reduced to 75 mCi for participants experiencing any of the dose-limiting toxicities. The third and fourth therapeutic doses could be reduced to 75 mCi on the basis of dosimetry assessment after administration of 10 mCi of I-131-1095 prior to the third dosing cycle. Participants also received the label dosage of enzalutamide once daily for up to 53 weeks..
