Stereotactic Body Radiation Therapy With REGN2810 and/or Ipilimumab Before Surgery in Treating Participants With Progressive Advanced or Oligometastatic Prostate Cancer
R2810-ONC-16XX: A Phase 1 Neoadjuvant Study of Stereotactic Body Radiation Therapy With Systemic REGN2810 and Intraprostatic Ipilimumab, Alone or in Combination, in Patients With Locally Advanced Prostate Cancer Prior to Radical Prostatectomy
Study Overview
Status
Conditions
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the safety and tolerability for an established effective dose of systemic REGN2810 and intraprostatic ipilimumab with stereotactic body radiation therapy (SBRT) in patients with locally advanced prostate cancer with or without oligometastatic disease.
SECONDARY OBJECTIVES:
I. To determine overall pathologic response rate after radical prostatectomy. II. To determine prostate-specific antigen (PSA) progression free survival in men treated with REGN2810 and intraprostatic ipilimumab with SBRT.
III. To determine radiographic progression free survival in men treated with REGN2810 and intraprostatic ipilimumab with SBRT.
IV. Acute and chronic adverse events (AEs).

Exclusion Criteria:
- Is currently participating and receiving study therapy or has participated in a study of an investigational agent within 4 weeks of the first dose of treatment
- Prior treatment with an agent that blocks PD-1/PD-L1 pathway or other immune modulating agents within fewer than 4 weeks of 4 half-lives
- Has a diagnosis of immunodeficiency or is receiving any systemic steroid therapy or any form of immunosuppressive therapy within 7 days prior to day 1 of trial treatment

- Has had prior treatment with idelalisib
- Has had prior or current treatment with Androgen Deprivation Therapy
Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., ≤ grade 1 or at baseline) from adverse events due to a previously administered agent

- Has evidence of interstitial lung disease, active, non-infectious pneumonitis
- Has evidence of significant liver disease
- Has an active infection requiring systemic therapy; prior to dosing with REGN2810 the subject must be at least 5 half-lives from their last dose of antibiotic
- Has a history of listeriosis or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
- Has psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
- Has a contraindication to administration of amoxicillin, ampicillin, ciprofloxacin, erythromycin, gentamycin, penicillin, trimethoprim/sulfamethoxazole, and vancomycin

- Has contraindication to administration of non-steroidal anti-inflammatory drugs (NSAIDS)
- Is or has an immediate family member (spouse or children) who is investigational site or staff directly involved with this trial, unless prospective Institutional Review Board (IRB) approval (by chair or designee) is given allowing exception to this criterion for a specific subject
