Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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 acid (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. Patients undergo blood sample collection, bone scan, and computed tomography (CT) or magnetic resonance imaging (MRI) throughout the study.
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. Patients undergo blood sample collection, bone scan, and CT or MRI throughout the study.
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. Patients undergo blood sample collection, bone scan, and CT or MRI throughout the study.
After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 2 years.

Inclusion Criteria
* PHASE 2: ECOG performance status =\< 2 (Karnofsky \>= 60%)
* 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
* 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

* 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

* Medications or substances that are strong inducers of CYP3A4/5 or CYP2C19 must be stopped at least 3 weeks prior to the first M3814 dose.
* Drugs mainly metabolized by CYP3A with a narrow therapeutic index (as judged by the Investigator or authorized designee) must be discontinued at least 1 day prior to first M3814 dose.
* Note: Because the lists of these agents are constantly changing, it is important to regularly consult a frequently- updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the- counter medicine or herbal product.
