Summary

This phase I/II trial studies the best dose of M3814 when given together with radium-223 dichloride or with radium-223 dichloride and avelumab and to see how well they work in treating patients with castrate-resistant prostate cancer that had spread to other places in the body (metastatic). M3814 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radioactive drugs, such as radium-223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This study is being done to find out the better treatment between radium-223 dichloride alone, radium-223 dichloride in combination with M3814, or radium-223 dichloride in combination with both M3814 and avelumab, to lower the chance of prostate cancer growing or spreading in the bone, and if this approach is better or worse than the usual approach for advanced prostate cancer not responsive to hormonal therapy.

Objectives

PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of peposertib (M3814) in combination with radium-223 dichloride or in combination with radium-223 dichloride and avelumab in patients with advanced metastatic castrate-resistant prostate cancer (mCRPC) based on dose limiting toxicities (DLTs) in the doublet or triplet combinations. (Phase 1)
II. Radiographic progression free survival (rPFS) will be evaluated based on both skeletal and extraskeletal progression following Prostate Cancer Working Group 3 (PCWG3) methodology. (Phase 2)

SECONDARY OBJECTIVES:
I. To determine the time to the first symptomatic skeletal event [SSE].
II. To determine the safety of radium-223 dichloride, M3814, and avelumab combination treatment.
III. To observe and record anti-tumor activity.
IV. To evaluate progression free survival (PFS) and overall survival (OS).
V. To evaluate symptomatic skeletal events (SSE) per standardized case report form (CRF) distinguishing between pathologic and non-pathogenic fractures.
VI. To explore patient-reported symptomatic adverse events (AE) for tolerability of each treatment arm.
VII. To examine the radium-223 dichloride bio-distribution and absorbed dose in each bone metastatic lesions as well as elsewhere in the body including critical organs using dosimetry.

EXPLORATORY OBJECTIVES:
I. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES), and messenger ribonucleic acid (RNA) sequencing (RNAseq), in order to:
Ia. Identify potential predictive and prognostic biomarkers beyond any genomic alteration by which treatment may be assigned, and
Ib. Identify resistance mechanisms using genomic deoxyribonucleic (DNA)- and RNA-based assessment platforms.
II. To contribute genetic analysis data from de-identified biospecimens to Genomic Data Commons (GDC), a well annotated cancer molecular and clinical data repository, for current and future research; specimens will be annotated with key clinical data, including presentation, diagnosis, staging, summary treatment, and if possible, outcome.
III. To bank plasma and peripheral immune cells from patients to assess predictive biomarkers of response at the Experimental Therapeutics Clinical Trials Network (ETCTN) biorepository at Nationwide Children's Hospital.
IV. To correlate change in level of total alkaline phosphatase, bone-specific alkaline phosphatase, and serum osteocalcin to rPFS and OS.

OUTLINE: This is a phase I, dose-escalation study of peposertib, followed by a phase II study. Patients are randomized to 1 of 3 arms.

ARM A: Patients receive radium-223 dichloride intravenously (IV) over 1 minute on day 1. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive radium-223 dichloride as in Arm A and peposertib orally (PO) once daily (QD) or twice daily (BID) on days 3-26. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM C: Patients receive radium-223 dichloride IV as in Arm A and peposertib PO QD or BID as in Arm B. Patients also receive avelumab IV over 60 minutes on days 1 and 15 of cycles 2-6. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 2 years.

Eligibility

  1. PHASE 1: Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (Karnofsky >= 70%)
  2. PHASE 2: ECOG performance status =< 2 (Karnofsky >= 60%)
  3. Unless a patient has had orchiectomy by surgery, the patient is expected to be on antiandrogen therapy (ADT) for “medical castration”. ADT needs to be maintained throughout the study. Testosterone level should be checked, and kept consistently lower than 50 ng/dL, similar to that obtained with bilateral orchiectomy
  4. Progressive castration-resistant prostate cancer with two or more skeletal metastases identified by 99mTC bone scintigraphy. One or more lymph node metastases allowed, but not mandatory. Lymph node metastases in each individually must measure less than 3 cm in the longest dimension. Visible visceral organ metastases are not allowed. A diagnosis of prostate cancer must have been histologically confirmed at any time point
  5. Baseline prostatic specific antigen (PSA) level of 1 ng/mL or higher with evidence of progressively increasing PSA values (two consecutive increases over the previous reference value)
  6. Progression after at least one of the following: abiraterone, enzalutamide, apalutamide, darolutamide, or taxane chemotherapy (docetaxel, cabazitaxel). There is no maximum number of prior therapies. Prior immunotherapies (for example, Sipuleucel-T or pembrolizumab) do not exclude the patient from participation

  21. Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
  22. Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional classification. To be eligible for this trial, patients should be class 2B or better
