Prostate Cancer Clinical Trial
Official title:
Phase I/II Trial of Pembrolizumab and Androgen-receptor Pathway Inhibitor With or Without 225Ac-J591 for Progressive Metastatic Castration Resistant Prostate Cancer
This is a phase I/II study investigating the combination of 225Ac-J591 (a drug that can deliver radiation to prostate cancer cells) with pembrolizumab (immunotherapy, a drug that increases the immune system's ability to destroy cancer cells). This study will assess whether 225Ac-J591 + pembrolizumab + androgen receptor pathway inhibitor (ARPI) is more effective against prostate cancer than pembrolizumab + ARPI alone.

Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention. - Diagnosis of deep vein thrombosis and/or pulmonary embolus within 1 month of C1D1 - Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator - Has received radiotherapy within 4 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (=2 weeks of radiotherapy) to non-CNS disease. - Patients on stable dose of bisphosphonates or denosumab, which have been started no less than 4 weeks prior to treatment start, may continue on this medication, however patients are not allowed to initiate bisphosphonate/Denosumab therapy during the DLT-assessment period of the study. These drugs may be added after week 12. - Unless azoospermia is present (whether due to surgery or underlying medical condition), having partners of childbearing potential and not willing to use a method of birth control deemed acceptable by the principal investigator and chairperson during the study and for 4 months after last study drug administration. - Is expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment - Has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of study drug. Administration of killed vaccines are allowed. - Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or any of its excipients. - Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease. - Has an active infection requiring systemic therapy at the time of treatment initiation - Has a known history of active TB (Bacillus Tuberculosis) - Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial - Has had an allogenic tissue/solid organ transplant |
