NCT03770455

Brief Summary

This is a nonrandomized, open-label trial of avelumab in subjects with metastatic castration-resistant prostate cancer (mCRPC) experiencing PSA or radiographic progression while receiving 2nd generation ADT (abiraterone / enzalutamide/ apalutamide or darolutamide). Metastases must be radiographically evident by whole body bone scintigraphy or CT/MRI scan. Thirteen African American subjects will be enrolled into the initial cohort. If at least one positive response (PSA decrease by \>50% and or radiographic per RECIST 1.1) is found, the study will be expanded to accrue a total of 27 patients. The trial will be conducted in accordance with Good Clinical Practices. Subjects enrolled in the study will receive avelumab 10 mg/kg every 2 weeks (Q2W) and continue their previously started 2nd generation ADT (abiraterone or enzalutamide). Treatment with avelumab will continue until documented confirmed disease progression, unacceptable AEs, intercurrent illness that prevents further administration of treatment, Investigator's decision to withdraw the subject, subject discontinuation from the study, noncompliance with trial treatment or procedure requirements, subject receives 52 administrations of avelumab (approximately 2 years), or administrative reasons requiring the cessation of treatment. After the end of treatment, each subject will be followed for 30 days for AE monitoring (serious AEs will be collected for 90 days after the end of treatment or 30 days after the end of treatment if the subject initiates new anticancer therapy, whichever is earlier). Subjects who discontinue treatment for reasons other than disease progression will remain on study and continue to undergo study-related disease assessments until documented disease progression, initiation of a new non-study prostate cancer treatment, withdrawal of consent, or becoming lost to follow-up. All subjects will enter survival follow up, and will be contacted at their regularly scheduled clinic visit, or by telephone approximately every 6 months, until death or withdrawal of consent or end of study.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Prostate-Specific Antigen (PSA) Response Greater Than or Equal to 50%

    The primary endpoint is a PSA response at 8 weeks or greater from starting study treatment and with a minimum of 3 treatments administered. A PSA response is defined as a ≥50% PSA decline at 8 weeks or greater from the time of starting study treatment. The two-stage minimax design of the study will be utilized to determine whether further investigation of the study drug is warranted.

    8 Weeks, 6 months

Secondary Outcomes (3)

  • PSA Progression-free Survival (PFS)

    pPFS will be assessed 12 months after enrollment of last subject.

  • Radiographic Progression-free Survival (PFS)

    rPFS will be assessed 12 months after enrollment of last subject.

  • Overall Survival (OS)

    Overall survival with be assessed at 3 years from time of enrollment of last study subject.

  • Be ≥18 years of age on day of signing informed consent.
  • Have histologically or cytologically confirmed adenocarcinoma of the prostate without small cell histology. Diagnosis must be stated in a pathology report.
  • Have evidence of metastatic disease as determined by CT/MRI scans and/or bone metastases by whole body bone scintigraphy. (Use MRI if CT is contraindicated, and for imaging of the brain if clinically indicated).

This treatment must be continued throughout the study.
  • Be receiving and tolerating either abiraterone acetate, enzalutamide, apalutamide or darolutamide for at least 8 weeks prior to documented disease progression. Note: the 2nd generation ADT that the patient is currently progression on needs to be the first 2nd gen ADT used in the CRPC setting

Limitations and Caveats

Study did not reach target number of participants needed to reach target power for statistically reliable results due to poor recruitment during Coronavirus Disease 2019 (COVID-19) pandemic and early termination of study. Study closed early due to safety concerns regarding rapid clinical progression of several participants, therefore, the secondary outcome measures were not analyzed and no data was reported for those outcome measures, so they were deleted from the study record.
