Clinical trial: Ipilimumab and Nivolumab in Treating Patients With Recurrent Stage IV HER2 Negative Inflammatory Breast Cancer

Summary: The purpose of this research study is to look at the efficacy (the effect on tumor) and the safety (the effect on body) of the study drugs when given as a combination in patients with metastatic recurrent epidermal growth factor receptor 2 (HER2) negative inflammatory breast cancer. This is a phase II study of 2 drugs used in combination: nivolumab and ipilimumab. The combination of these drugs is already approved by the Food and Drug Administration (FDA) to treat advanced melanoma (a type of skin cancer). Nivolumab and ipilimumab are not approved by the FDA for patients with metastatic recurrent HER2 negative inflammatory breast cancer, hence the treatment is considered experimental or investigational.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine progression free survival (PFS) in patients with newly recurrent HER2 negative inflammatory breast cancer (IBC) treated with nivolumab and ipilimumab according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1.
  SECONDARY OBJECTIVES:
  I. To assess the overall response rate (ORR) and clinical benefit rate (CBR) according to RECIST criteria v1.1, in patients with recurrent IBC treated with nivolumab and ipilimumab.
  II. To assess overall survival in patients with recurrent HER2 negative IBC treated with nivolumab and ipilimumab.
  III. To assess the safety and tolerability of nivolumab and ipilimumab in patients with recurrent IBC according to the National Cancer Institute Common Terminology Criteria for Adverse Events v 4.03.
  TERTIARY OBJECTIVES:
  I. To assess the predictive value of baseline iSCORE and programmed cell death 1 ligand 1 (PDL-1) expression using archival tissue samples as well as any standard of care tissue obtained during study treatment.
  II. To assess the predictive value of circulating cell-free tumor DNA (ctDNA) and immune signature by exosome analysis using blood samples at baseline.
  OUTLINE:
  Patients receive nivolumab intravenously (IV) over 30 minutes every 2 weeks (Q2W) and ipilimumab IV over 90 minutes every 6 weeks (Q6W) in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up every 4 weeks for 12 weeks, and then every 3 months for up to 2 years.

Eligibility: Inclusion Criteria:
  -  Patients must have histologically or cytologically confirmed stage IV breast carcinoma with a previous clinical diagnosis of IBC based on the presence of inflammatory changes in the involved breast, such as diffuse erythema and edema (peau d'orange), with or without an underlying palpable mass involving the majority of the skin of the breast; pathological evidence of dermal lymphatic invasion should be noted but is not required for diagnosis
  -  Patients must have local or metastatic recurrence of IBC after prior surgery
  -  Patients must have a metastatic tumor negative for HER2; the lack of HER2 overexpression by immunohistochemistry (IHC), is defined as 0 or 1+ where as hyperexpression is defined as 3+; if equivocal IHC, 2+, the tumor must be non-gene amplified by fluorescence in situ hybridization (FISH) performed upon the primary tumor or metastatic lesion (ratio < 2 and HER2 copy number < 4)
