NCT06329830

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • 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

  • 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.

Study Arms (1)

177Lu-PSMA-617 in Combination with Niraparib/Abiraterone Acetate plus Prednisone

EXPERIMENTAL

177Lu-PSMA-617 will be administered per standard of care at 7.4 gigabecquerel (GBq) (200 mCi) via intravenous (IV) infusion once every cycle (6 weeks) for 6 cycles. Niraparib/Abiraterone Acetate (Nira/AA) will be taken orally by the participant daily until disease progression or unacceptable toxicity. The starting dose level is 150 mg/1000 mg Nira/AA. Other dose levels include 200 mg/1000 mg, 100 mg/1000 mg, or 50 mg/500 mg Nira/AA once daily. Prednisone (5 mg) will be taken orally by the participant twice daily each day that Nira/AA is taken.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • Should have previous therapy with at least one androgen receptor pathway inhibitor in castration resistant or sensitive setting, and
  • 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:
  • PSA progression: based on rising values at a minimum of 1-week intervals. The minimum starting value of PSA being 1 ng/mL
  • 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:
  • Metastatic disease in the bones visible on technetium-99m-MDP (methylene diphosphonate) bone scan ("bone scan") and/or
  • Pathologically enlarged lymph nodes of any distribution and/or
  • Visceral metastasis of any size or distribution.
  • +6 more criteria

You may not qualify if:

  • Pathological finding consistent with small cell or neuroendocrine carcinoma of the prostate
  • Prior therapy with poly adenosine diphosphate (ADP)-ribose polymerase (PARP) inhibitor
  • Prior therapy with 177Lu-PSMA 617 therapy. Exception: prior therapy with radium 223 is allowed if last dose was ≥ 6 months from study therapy. Note that other prior radiation therapy (such as external beam radiation therapy or brachytherapy) to prostate or other metastatic sites is allowed.
  • History of adrenal dysfunction
  • Active malignancies (i.e., progressing or requiring treatment change in the last 24 months) other than the disease being treated under study. The only allowed exceptions are:
  • Non-muscle invasive bladder cancer
  • Skin cancer (non-melanoma or melanoma) treated within the last 24 months that is considered completely cured

  • Current evidence within 3 months of study consent of any of the following: severe/unstable angina, myocardial infarction, symptomatic congestive heart failure, clinically significant arterial or venous thromboembolic events (i.e., pulmonary embolism), or clinically significant ventricular arrhythmias.
  • Presence of sustained uncontrolled hypertension (systolic blood pressure \>160 mm Hg or diastolic blood pressure \>100 mm Hg). Participants with a history of hypertension are allowed, provided that blood pressure is controlled to within these limits by an antihypertensive treatment.
  • Known allergies, hypersensitivity, or intolerance to the excipients of Nira/AA tablets.
  • Current evidence of any medical condition that would make prednisone use contraindicated.
  • Received an investigational intervention (including investigational vaccines) or used an invasive investigational medical device within 30 days before the planned first dose of study medication
