• ELIGIBILITY CRITERIA FOR SCREENING BIOPSY (STEP 0)
• Women of childbearing potential must have a negative serum pregnancy test within 2 weeks prior to registration; patients that are pregnant or breast feeding are excluded; a female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
• Has not undergone a hysterectomy or bilateral oophorectomy; or
• Has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
• Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 4 months after completion of study; should a woman become pregnant or suspect while she or her partner is participating in this study, she should inform her treating physician immediately

• Patients must have progressed following at least one line of standard systemic therapy and there must not be other approval/standard therapy available that has been shown to prolong overall survival (i.e. in a randomized trial against another standard treatment or by comparison to historical controls); patients who cannot receive other standard therapy that has been shown to prolong overall survival due to medical issues will be eligible, if other eligibility criteria are met; if the patient is currently receiving therapy, the clinician must have assessed that the current therapy is no longer benefitting the patient prior to enrolling on MATCH, regardless of whether it is considered standard OR
• Patients for whose disease no standard treatment exists that has been shown to prolong overall survival
• NOTE: No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer; in situ cervical cancer; adequately treated stage I or II cancer from which the patient is currently in complete remission; any other cancer from which the patient has been disease-free for 5 years
• Patients must have measurable disease
• Patients must meet the criteria below and have received results from one of the designated outside laboratories indicating a "rare variant" that is an actionable Mutation of Interest (aMOI) for specific select subprotocols.
• The following requirements apply:
• The outside laboratory specifically notified the site that patient may be a potential candidate for MATCH due to a detected "rare variant"; the outside lab reports are NOT sufficient for this purpose
• NOTE: The content and format of these specific notifications for the Outside Assay process will vary depending on the designated outside lab in question, as they are each responsible for their own outreach efforts; it is strongly recommended that the designated outside laboratory be contacted to confirm the format and receipt of this notification prior to registering any patients to Step 0
• Patients with an applicable "rare variant" must be able to meet the eligibility criteria for the appropriate subprotocols within 4 weeks following notification of treatment assignment
• NOTE: The receipt of this notification (and the start of the associated deadline for Step 1 registration) may occur shortly after Step 0 registration, since these patients will not be submitting tissue for screening purposes; however, for certain "rare variant" arms, submission of archival tissue for central immunohistochemistry (IHC) testing may be required
• Registration to Step 0 must occur after stopping prior systemic anti-cancer therapy; there is no specific duration for which patients must be off treatment prior to registration to Step 0, as long as all eligibility criteria are met
• There is no particular window of time after notification of potential eligibility from an outside lab in which the patient must be registered to Step 0, but treatment slots will be assigned on a first come, first serve basis to those who do register to Step 0, and are not held for those notified of potential eligibility who do not register to Step 0
• Patients may have received other non-targeted, immunotherapy or targeted treatment between the prior genetic testing at the outside lab and registration to Step 0; the decision to stop such treatment in favor of participation in MATCH, if no further clinical benefit is expected, is per the treating physician's discretion; documentation of a lack of response to the prior treatment is not required in these cases
• NOTE: Other potential aMOIs that would be eligibility criteria for "NON RARE" arms, as determined by the designated laboratories, are not applicable for this process in MATCH
• NOTE: Tumor tissue for the confirmation of "rare variant" by the MATCH assay is to be submitted, preferably from the same time of collection as that evaluated by the designated outside laboratory

• Patients must be able to swallow tablets or capsules; a patient with any gastrointestinal disease that would impair ability to swallow, retain, or absorb drug is not eligible
• Patients who are human immunodeficiency virus (HIV)-positive are eligible if:
• CD4+ cell count greater or equal to 250 cells/mm^3
• If patient is on antiretroviral therapy, there must be minimal interactions or overlapping toxicity of the antiretroviral therapy with the experimental cancer treatment; for experimental cancer therapeutics with CYP3A/4 interactions, protease inhibitor therapy is disallowed; suggested regimens to replace protease inhibitor therapy include dolutegravir given with tenofovir/emtricitabine; raltegravir given with tenofovir and emtricitabine; once daily combinations that use pharmacologic boosters may not be used

• NOTE: Prostate cancer patients may continue their luteinizing hormone-releasing hormone (LHRH) agonist
• NOTE: For patients entering the study via the original screening process, patients may receive non-protocol treatment after biopsy (if clinically indicated) until they receive notification of results; however, lack of response must be documented prior to registration to Step 1; new non-protocol treatment will NOT be permitted as intervening therapy after registration to Step 0; the only intervening treatment permitted is prior therapy that the patient already received prior to Step 0 registration; the decision to stop the intervening non-protocol treatment will be left up to the treating physician if patient has an aMOI; however, patients will need to be off such therapy for at least 4 weeks before receiving any MATCH protocol treatment
• NOTE: For patients entering the study via a designated outside laboratory, no intervening systemic non-protocol treatment is permitted after Step 0 registration; all other eligibility requirements still apply to these patients, including the washouts for prior therapy noted above in this section, the time restrictions outlined, and the eligibility criteria for the intended subprotocol

A taxane regimen is defined as a minimum exposure of 2 cycles of a taxane. If a patient has received only 1 taxane regimen, the patient is eligible if: 1. The patient is not willing to receive a second taxane regimen, or 2. The patient's physician deems him unsuitable to receive a second taxane regimen (e.g. frailty assessed by geriatric or health status evaluation or intolerance). 11. Patients must have progressive mCRPC. Documented progressive mCRPC will be based on at least 1 of the following criteria: 1. Serum PSA progression defined as 2 consecutive increases in PSA over a previous reference value measured at least 1 week prior. The minimal start value is 2.0 ng/mL. 2. Soft-tissue progression defined as an increase ≥20% in the sum of the diameter (SOD) (short axis for nodal lesions and long axis for non-nodal lesions) of all target lesions based on the smallest SOD since treatment started or the appearance of one or more new lesions. 3. Progression of bone disease: evaluable disease or new bone lesions(s) by bone scan (2+2 PCWG3 criteria, Scher et al 2016). 12. Patients must have≥ 1 metastatic lesion that is present on baseline CT, MRI, or bone scan imaging obtained ≤28 days prior to beginning study therapy. 13. Patients must have recovered to ≤ Grade 2 from all clinically significant toxicities related to prior therapies (i.e. prior chemotherapy, radiation, immunotherapy, etc.). 14. Patients must have adequate organ function: 1. Bone marrow reserve:
• White blood cell (WBC) count ≥2.5 x 109/L (2.5 x 10^9/L is equivalent to 2.5 x 10^3/µL and 2.5 x K/µL and 2.5 x 10^3/cumm and 2500/µL) OR absolute neutrophil count (ANC) ≥1.5 x 10^9/L (1.5 x 10^9/L is equivalent to 1.5 x 10^3/µL and 1.5 x K/µL and 1.5 x 10^3/cumm and 1500/µL)
• Platelets≥ 100 x 10^9/L (100 x 10^9/L is equivalent to 100 x 10^3/µL and 100 x K/µL and 100 x 10^3/cumm and 100,000/µL)
• Hemoglobin≥ 9 g/dL (9 g/dL is equivalent to 90 g/L and 5.59 mmol/L) 2. Hepatic:
• Total bilirubin ≤1.5 x the institutional upper limit of normal (ULN). For patients with known Gilbert's Syndrome ≤ 3 x ULN is permitted
• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤3.0 x ULN OR ≤5.0 x ULN for patients with liver metastases 3. Renal:
• Serum creatinine ≤1.5 x ULN or creatinine clearance ≥50 mL/min 15. Albumin >3.0 g/dL (3.0 g/dL is equivalent to 30 g/L) 16. Patients on a stable bisphosphonate or denosumab regimen for ≥30 days prior to randomization are eligible. 17. HIV-infected patients who are healthy and have a low risk of AIDS-related outcomes are included in this trial. For patients who have partners of childbearing potential: 18. Partner and/or patient must use a method of birth control with adequate barrier protection, deemed acceptable by the principle investigator during the study and for 3 months after last study drug administration.
• Patients who meet any of the following criteria will be excluded from the study: 1. Previous treatment with Strontium-89, Samarium-153, Rhenium-186, Rhenium-188, Radium-223 or hemi-body irradiation within 6 months prior to randomization. Previous PSMA-targeted radioligand therapy is not allowed. 2. Any systemic anti-cancer therapy (e.g. chemotherapy, immunotherapy or biological therapy [including monoclonal antibodies]) within 28 days prior to day of randomization. 3. Any investigational agents within 28 days prior to day of randomization. 4. Known hypersensitivity to the components of the study therapy or its analogs. 5. Other concurrent cytotoxic chemotherapy, immunotherapy, radioligand therapy, or investigational therapy. 6. Transfusion within 30 days of randomization. 7. Patients with a history of CNS metastases must have received therapy (surgery, radiotherapy, gamma knife) and be neurologically stable, asymptomatic, and not receiving corticosteroids for the purposes of maintaining neurologic integrity. Patients with epidural disease, canal disease and prior cord involvement are eligible if those areas have been treated, are stable, and not neurologically impaired. For patients with parenchymal CNS metastasis (or a history of CNS metastasis), baseline and subsequent radiological imaging must include evaluation of the brain (MRI preferred or CT with contrast). 8. A superscan as seen in the baseline bone scan. 9. Symptomatic cord compression, or clinical or radiologic findings indicative of impending cord compression. 10. Concurrent serious (as determined by the Principal Investigator) medical conditions, including, but not limited to, New York Heart Association class III or IV congestive heart failure, history of congenital prolonged QT syndrome, uncontrolled infection, active hepatitis B or C, or other significant co-morbid conditions that in the opinion of the investigator would impair study participation or cooperation. 11. Diagnosed with other malignancies that are expected to alter life expectancy or may interfere with disease assessment. Patients with adequately treated non-melanoma skin cancer, superficial bladder cancer and patients with prior history of malignancy who have been disease free for more than 3 years are eligible.
