Protocol Interventions
Drug: AAA617, Drug: Gonadotropin-releasing hormone (GnRH) analogues, Drug: Gonadotropin-releasing hormone (GnRH) antagonists
Brief Summary
This study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)>=
Protocol Interventions
Radiation: Radiation SBRT only
Brief Summary
This is a four-part study evaluating the safety and efficacy of a PSMA-directed radioantibody (rosopatamab tetraxetan, conjugated to either In-111 or Ac-225). Part 1 will consist of one administration of In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants then will be enrolled into either Part 2 (Dose Optimization) or Part 3 (Dose Escalation and Expansion) depending on their prior treatment history. Part 4 will be an extended regimen in dose escalation and expansion. Participants qualifying for Part 2 will be randomized to receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle (dose administration on Day 1 and Day 15) at either 45 or 60 kBq/Kg. Participants qualifying for Part 3 must have received prior Lu-177-PSMA-radioligand therapy and will receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle at 45, 55, or 60 kBq/Kg. Dose limiting toxicities (DLTs) will be monitored in Part 3 to determine the recommended phase 2 dose (RP2D), and the study may enroll additional participants to be treated with the RP2D dose level. Participants qualifying for Part 4 will initially receive two doses (dose administration on Day 1 and Day 15) at the dose level selected in Part 2, followed by a single third dose of Ac-225 rosopatamab tetraxetan administered approximately 12 weeks after completion of the Part 2 fractionated dosing regimen. The starting dose level for Part 4 will be 22 kBq/kg (or fixed activity equivalent). Dose limiting toxicities (DLTs) will be monitored following administration of the third dose in Part 4 to determine the recommended phase 2 dose (RP2D) of a third dose of Ac-225 rosopatamab tetraxetan. Participants enrolled into any part will attend study visits which will include blood samples, electrocardiogram (ECG), radiographic imaging, and physical examinations along with other assessments.
Protocol Interventions
Biological: Single dose 22 kBq/kg or equivalent fixed dose activity Ac-225 rosopatamab tetraxetan, Biological: Single dose 34 kBq/kg or equivalent fixed dose activity Ac-225 rosopatamab tetraxetan, Biological: Single dose 45 kBq/kg or equivalent fixed dose activity Ac-225 rosopatamab tetraxetan
Brief Summary
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.
Protocol Interventions
Procedure: Biospecimen Collection, Procedure: Computed Tomography, Radiation: External Beam Radiation Therapy, Procedure: Magnetic Resonance Imaging, Procedure: Positron Emission Tomography, Other: Quality-of-Life Assessment, Other: Questionnaire Administration
Brief Summary
The purpose of this study is to identify the recommended phase 2 regimen(s) RP2R(s) of pasritamig and combination regimens in Part 1 (dose escalation) and to determine safety at the putative RP2R(s) of pasritamig with the combination regimens in Part 2 (dose expansion).
Protocol Interventions
Drug: Pasritamig, Drug: Cetrelimab, Drug: Cabazitaxel, Drug: Docetaxel, Drug: Apalutamide, Drug: Enzalutamide, Drug: Darolutamide, Drug: Abiraterone acetate plus prednisone (AAP), Drug: Lutetium Lu-177 vipivotide tetraxetan, Drug: JNJ-101556143
Brief Summary
The purpose of this study is to evaluate the efficacy and safety of lutetium (177Lu) vipivotide tetraxetan (AAA617) in participants with oligometastatic prostate cancer (OMPC) progressing after definitive therapy to their primary tumor. The data generated from this study will provide evidence for the treatment of AAA617 in early-stage prostate cancer patients to control recurrent tumor from progressing to fatal metastatic disease while preserving quality of life by delaying treatment with androgen deprivation therapy (ADT).
Protocol Interventions
Drug: AAA617
Brief Summary
This study is a first-in-human, Phase 1, open-label, multicenter study to assess the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and the preliminary efficacy of JANX007 in adults with metastatic castration-resistant prostate cancer (mCRPC).
Protocol Interventions
Biological: JANX007, Drug: Darolutamide
Brief Summary
The aim of this study is to determine the safety and efficacy of 67Cu-SAR-bisPSMA in participants with PSMA-expressing metastatic castrate resistant prostate cancer.
Protocol Interventions
Drug: 64Cu-SAR-bisPSMA, Drug: 67Cu-SAR-bisPSMA
Brief Summary
This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen [PSA] after surgical removal of the prostate cancer).
A second question tests treatment in patients with biochemical recurrence who show prostate cancer spreading outside the pelvis (metastasis) by positron emission tomography (PET) imaging. In these patients, the benefit of adding metastasis-directed radiation to enhanced therapy (apalutamide in combination with abiraterone + prednisone) is tested.
Diagnostic procedures, such as PET, may help doctors look for cancer that has spread to the pelvis. Androgens are hormones that may cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Metastasis-directed targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.

Brief Summary
This phase I/II trial studies the best dose of M3814 when given together with radium-223 dichloride or with radium-223 dichloride and avelumab and to see how well they work in treating patients with castrate-resistant prostate cancer that had spread to other places in the body (metastatic). M3814 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radioactive drugs, such as radium-223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This study is being done to find out the better treatment between radium-223 dichloride alone, radium-223 dichloride in combination with M3814, or radium-223 dichloride in combination with both M3814 and avelumab, to lower the chance of prostate cancer growing or spreading in the bone, and if this approach is better or worse than the usual approach for advanced prostate cancer not responsive to hormonal therapy.
Protocol Interventions
Drug: Avelumab, Procedure: Biospecimen Collection, Procedure: Bone Scan, Procedure: Computed Tomography, Procedure: Magnetic Resonance Imaging, Drug: Peposertib, Other: Questionnaire Administration, Radiation: Radium Ra 223 Dichloride
