Who may be able to join
- PRE-REGISTRATION: Histological or cytological evidence of prostate cancer. Patients with variant histologies including neuroendocrine, small cell and sarcomatoid prostate cancer are allowed to enroll and these will not be used as selection criteria for individual arms. Central pathology review is not required.
- PRE-REGISTRATION: Measurable disease and/or non-measurable metastatic disease per RECIST version 1.1.
- PRE-REGISTRATION: Tissue procured within 12 months of pre-registration (metastatic disease preferred over primary tissue, though both are acceptable) available for submission per Section 6.2. For patients who have progressed on A032102 and are pre-registering again, repeat tissue procurement will not be mandated.
- PRE-REGISTRATION: Molecular report available performed as part of standard of care testing via any Clinical Laboratory Improvement Act (CLIA)-certified next generation sequencing (NGS) assay. Patients may be assigned based on pre-determined qualifying molecular/DNA alterations as stated in Section 4.8 after receipt of local molecular testing by the A032102 molecular tumor board (MTB). Final determination of arm assignment will be determined by the MTB. For qualifying DNA alteration determined by the MTB, testing may be from tumor tissue collected at any time or circulating tumor DNA (ctDNA) within 12 months of pre-registration. If no qualifying DNA alteration is identified based on the CLIA-certified next generation sequencing assay and MTB review, Caris testing, should be performed for both DNA/RNA profiling. Arm assignment based RNA requires testing of tumor tissue collected within 12 months of pre-registration and MTB review.
- PRE-REGISTRATION: Age ≥ 18 years.
- REGISTRATION: Progressive mCRPC as defined: 1) castrate levels of serum testosterone \< 50 ng/dL AND one or more of the following criteria (choose all the apply):
Show all 77Show fewer
- PSA progression, defined by at least 2 consecutive rising PSA values at a minimum of 1-week intervals with the most recent PSA value being 2.0 ng/mL or higher, if confirmed PSA rise is the only indication of progression. Patients who received an anti-androgen must have PSA progression after withdrawal of anti-androgen therapy.
- Radiographic progression per RECIST 1.1 criteria for soft tissue lesions
- Bone metastasis progression per Prostate Cancer Working Group 3 (PCWG3) criteria.
- REGISTRATION: Patients selected to receive lutetium Lu 177 vipivotide tetraxetan treatment are required to have prostate-specific membrane antigen (PSMA) positive mCRPC as determined by investigator assessment. For reference, in the VISION trial this was defined as at least 1 PSMA+ metastatic lesion (defined as uptake greater than that of liver parenchyma in lesions of any size in any organ system) and no PSMA- lesions (defined as uptake equal to or lower than that of liver parenchyma in any lymph node with a short axis of at least 2.5 cm, in any solid organ lesion with a short axis of at least 1.0 cm, or in any bone lesion with a soft-tissue component of at least 1.0 cm in the short axis).
- REGISTRATION: Prior treatment with androgen receptor signaling inhibitor (ARSI) in either the metastatic hormone sensitive setting or mCRPC is required. Prior taxane therapy in either metastatic hormone sensitive setting or mCRPC is mandated unless patient is taxane ineligible or the patient refuses taxane therapy. Prior lutetium LU177 vipivotide tetraxetan treatment is permitted but not mandated. Patients with known germline or somatic deleterious BRCA 1/2 mutations must have received a prior PARPi.

No treatment with radiation therapy within 2 weeks of registration.
- REGISTRATION: No major surgery within 4 weeks of registration.
- REGISTRATION: No prior treatment with EZH inhibitors.
- REGISTRATION: Prior treatment with cabazitaxel + carboplatin.
- REGISTRATION: None of the following conditions:

About this study
Official title: PREcision DIagnostics in Prostate Cancer Treatment (PREDICT)
This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells. Assigning patients to targeted treatment based on genetic testing may help shrink or slow the cancer from growing

What is being measured
The primary outcome is the main question the study is designed to answer.
Objective Response
Objective response is defined by modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Prostate Cancer Working Group 3 (PCWG3) for patients with measurable disease.
Measured: Within 6 months from the start of treatment
Secondary outcomes (7)
Radiographic Progression Free Survival (rPFS)
Radiographic progression is defined by PCWG-3 for patients with bone metastases and modified RECIST 1.1 criteria for patients with soft tissue metastases. The 9-month radiographic progression-free proportion will be estimated by treatment arm, where patients who withdraw from study after the start of treatment but prior to nine months of follow-up will be counted as failures. rPFS will be calculated from registration date under progression or death by any cause, censoring event-free patients at the date of last disease evaluation. Will be estimated in each treatment arm using the Kaplan-Meier method.
Measured: From initiation of treatment up to 9 months
Overall Survival
Will be calculated from registration date until death due to any cause, censoring event-free patients at the date of last contact. Will be estimated in each treatment arm using the Kaplan-Meier method.
Measured: Up to 5 years after study registration
Duration of Response
Will be estimated according to RECIST v1.1 for patients with measurable disease in each treatment arm using the cumulative incidence function.
Measured: Up to 5 years after study registration
Prostate-specific antigen response
Defined as greater than or equal to 50% decline in PSA from baseline using PCWG-3 criteria. Will be estimated as a proportion in each treatment arm.
Measured: Through treatment completion, an average of one year
Time to systematic skeletal events
A skeletal related event is defined as the use of external beam radiotherapy to relieve skeletal symptoms or the occurrence of new symptomatic pathological bone fractures (vertebral or non-vertebral) or the occurrence of spinal cord compression or a tumor related orthopedic surgical intervention. Will be estimated in each treatment arm using the cumulative incidence function.
Measured: Up to 5 years after registration
Time to subsequent anti-cancer therapy
Defined as time from registration to first subsequent anti-cancer therapy or death, censoring event-free patients at date of last follow-up. Will be estimated in each treatment arm using the cumulative incidence function.
Measured: Up to 5 years after registration
Rate of Grade 3+ AEs
Will be collected and graded according ot the NCI CTCAE v5.0 criteria and per PRO-CTCAE.
Measured: Up to 6 months after completion of study treatment

- Adult, Older adult
Key inclusion criteria (77 listed)
- PRE-REGISTRATION: Histological or cytological evidence of prostate cancer. Patients with variant histologies including neuroendocrine, small cell and sarcomatoid prostate cancer are allowed to enroll and these will not be used as selection criteria for individual arms. Central pathology review is not required.
- PRE-REGISTRATION: Measurable disease and/or non-measurable metastatic disease per RECIST version 1.1.
- PRE-REGISTRATION: Tissue procured within 12 months of pre-registration (metastatic disease preferred over primary tissue, though both are acceptable) available for submission per Section 6.2. For patients who have progressed on A032102 and are pre-registering again, repeat tissue procurement will not be mandated.
- PRE-REGISTRATION: Molecular report available performed as part of standard of care testing via any Clinical Laboratory Improvement Act (CLIA)-certified next generation sequencing (NGS) assay. Patients may be assigned based on pre-determined qualifying molecular/DNA alterations as stated in Section 4.8 after receipt of local molecular testing by the A032102 molecular tumor board (MTB). Final determination of arm assignment will be determined by the MTB. For qualifying DNA alteration determined by the MTB, testing may be from tumor tissue collected at any time or circulating tumor DNA (ctDNA) within 12 months of pre-registration. If no qualifying DNA alteration is identified based on the CLIA-certified next generation sequencing assay and MTB review, Caris testing, should be performed for both DNA/RNA profiling. Arm assignment based RNA requires testing of tumor tissue collected within 12 months of pre-registration and MTB review.
- PRE-REGISTRATION: Age ≥ 18 years.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Genetic testing, Valemetostat Tosylate and Magnetic Resonance Imaging in people with Castration-Resistant Prostate Carcinoma and Stage IVB Prostate Cancer AJCC v8, run by Alliance for Clinical Trials in Oncology at 108 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 77 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 108 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rana McKay, MD (858-822-6185, rmckay@health.ucsd.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective Response (time frame: Within 6 months from the start of treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06632977, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
