Targeted Treatment for Metastatic Prostate Cancer, The PREDICT Trial

Launched by ALLIANCE FOR CLINICAL TRIALS IN ONCOLOGY · Oct 7, 2024

ClinConnect Summary

The PREDICT Trial is a clinical study designed to explore how genetic testing can help doctors choose the best treatment options for patients with advanced prostate cancer that no longer responds to hormone therapy. In this trial, doctors will examine cancer tissue samples from patients to look for specific genetic changes. Based on these findings, patients may receive one of several treatments, including medications that can slow tumor growth or target cancer cells more effectively. This personalized approach aims to improve treatment outcomes for those with metastatic prostate cancer.

To participate in the trial, patients must be at least 18 years old and have been diagnosed with advanced prostate cancer that has shown signs of progression. They should have tissue samples available for testing and may need to have already tried certain cancer treatments. Throughout the trial, participants will receive close monitoring to assess how well the treatments are working and to manage any side effects. This study is currently recruiting patients, and those interested should discuss the opportunity with their healthcare provider to see if they meet the necessary criteria.

Eligibility criteria

• Inclusion Criteria:
• • 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):
• • 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.
