Clinical Trial Summary

The purpose of this research study is to test the safety and possible side effects of Lutetium-177 (177Lu)-Prostate-Specific Membrane Antigen (PSMA)-617 along with niraparib and abiraterone acetate plus prednisone when it is given to people diagnosed with metastatic castration-resistant prostate cancer (prostate cancer that has spread to other parts of the body and does not improve with hormonal therapies) at different dose levels. Once an optimal dose is selected, the researchers want to find out what how well these treatments work to improve survival and control the growth of the tumor.

Eligibility Inclusion Criteria: - Signed informed consent must be obtained prior to participation in the study - Adults = 18 years of age - Eastern Cooperative Oncology Group (ECOG) performance score of 0 to 2 - Life expectancy of greater than six months as determined by the treating physician - Evidence of metastatic castration resistant prostate cancer with histological or cytology confirmed adenocarcinoma. This can be based on prior biopsy of prostate or metastatic disease. 1. Should have previous therapy with at least one androgen receptor pathway inhibitor in castration resistant or sensitive setting, and 2. Should have prior therapy with at least one line of therapy with taxane chemotherapy in castration resistant or sensitive setting - Evidence of disease progression on current therapy which is based on either: 1. PSA progression: based on rising values at a minimum of 1-week intervals. The minimum starting value of PSA being 1 ng/mL 2. Radiologic progression: growth of known metastases or evidence of new metastases. - Evidence of PSMA positive disease based on PSMA positron emission tomography (PET)/computed tomography (CT) scan utilizing radiotracers F-18 piflufolastat PSMA or Ga-68 PSMA-11. PSMA positive is defined as having at least one tumor lesion with radiotracer uptake greater than normal liver. Patients will be excluded if any lesions exceeding size criteria in short axis [organs = 1 cm, lymph nodes = 2.5 cm, bones (soft tissue component) = 1 cm] have uptake less than or equal to uptake in normal liver. - Patients must have evidence of metastatic disease with at least one of the following: 1. Metastatic disease in the bones visible on technetium-99m-MDP (methylene diphosphonate) bone scan ("bone scan") and/or 2. Pathologically enlarged lymph nodes of any distribution and/or 3. Visceral metastasis of any size or distribution. - Adequate organ function: 1. Bone marrow reserve: absolute neutrophil count (ANC) = 1500 cells/microliter (uL), platelets = 100,000 cells/uL, hemoglobin = 9 g/dL 2. Hepatic function: total bilirubin = 2 × institutional upper limit of normal (ULN), for patients with known Gilbert syndrome = 3 × institutional ULN is permitted. Alanine transaminase (ALT) or aspartate transaminase (AST) = 3 × institutional ULN or = 5 × institutional ULN if liver metastases 3. Renal function: estimated glomerular filtration rate (eGFR) = 45 mL/min - Able to swallow the study medication tablets whole. - While on study medication and for 4 months following the last dose of study medication, participants must agree to use condom and an adequate contraception method for partner of childbearing potential.

A transfusion (platelets or red blood cells); 2. Hematopoietic growth factors; 3. Major surgery - Participants with known history of human immunodeficiency virus with 1 or more of the following: 1. Not receiving highly active antiretroviral therapy or on antiretroviral therapy for less than 4 weeks 2. Receiving antiretroviral therapy that may interfere with the study medication 3.

Outcome

Type Measure Description Time frame Safety issue
Primary Determination of the recommended phase 2 dose (RP2D) RP2D is determined based on the number of participants experiencing a dose-limiting toxicity (DLT) during phase 1. DLT is defined as any of the following treatment-related adverse events (AE) during Cycle 1, per Common Terminology Criteria for Adverse Events (CTCAE) V5.
Grade 4 thrombocytopenia or Grade =3 requiring platelet transfusion
Grade 4 anemia or Grade =3 requiring blood transfusion
Grade 4 neutropenia =7 days, or Grade 3/4 associated with infection or fever >38.5°C
Seizure, any grade
Concurrent elevation of ALT/AST >3×ULN & bilirubin >2×ULN, unless concurrent elevation is related to biliary obstruction or otherwise unrelated to study treatment
Grade 3 fatigue >5 days
Grade 3 nausea >3 days, despite optimal medical therapy
Grade =3 hypertension despite receiving >2 weeks of optimal medical therapy
Grade =3 vomiting or diarrhea persisting >3 days, despite optimal medical therapy
Other treatment-related Grade =3 non-hematologic toxicity except Grade 3 rash
6 weeks
Primary Prostatic-specific antigen (PSA)-50 response rate PSA-50 response is defined as a decrease = 50% from baseline to the lowest post-baseline PSA result. This measure will be expressed as a percent of participants who experience this response. 2 years
Secondary Radiographic progression-free survival (rPFS) rPFS is defined as the duration of time in months from treatment initiation to the first date of documented radiographic progression using conventional imaging or death due to any cause, whichever occurs first. The radiographic progression will be assessed per Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 for soft tissue and Prostate Cancer Working Group 3 (PCWG3) for bone lesions. 2 years
Secondary Overall survival (OS) OS is defined as the duration of time in months between the first dose of study therapy and death from any cause (participants who have not died will be censored at the most recent last-known-alive date). 2 years
Secondary PSA-80 response rate PSA-80 response is defined as a decrease = 80% from baseline to the lowest post-baseline PSA result. This measure will be expressed as a percent of participants who experience this response. 2 years
Secondary Duration of response (DOR) DOR is defined as the duration of time in months from when criteria are met for complete response (CR) or partial response (PR) (whichever is recorded first) until the date that recurrent or progressive disease is objectively documented or expiration. RECIST 1.1 criteria will be used for soft tissue lesions and PCWG3 criteria will be used for bone lesions. 2 years
Secondary Objective response rate (ORR) ORR is defined as the percent of participants who meet criteria for CR or PR. RECIST 1.1 criteria will be used for soft tissue lesions and PCWG3 criteria will be used for bone lesions. 2 years
