Brief Summary:
The goal of this protocol is to evaluate the safety and efficacy of an alternative systemic combination approach that omits or delays the use of chemotherapy in metastatic disease, while improving efficacy and durability of response. The approach combines two potentially effective and previously studied strategies: androgen receptor blockade and immune checkpoint therapy.

Condition or disease Intervention/treatment Phase
Breast Neoplasm Female Breast Cancer Breast Carcinoma Breast Tumor Drug: Nivolumab Drug: Ipilimumab Drug: Bicalutamide Phase 2

Detailed Description:

This is a phase II trial to assess the clinical efficacy and safety of nivolumab (anti-Programmed Death receptor-1, or anti-PD-1) combined with bicalutamide (Androgen Receptor (AR) inhibitor) and ipilimumab (anti-cytotoxic T-lymphocyte-associated protein 4, or anit-CTLA4) in patients with advanced breast cancer.

This study will include adult women with metastatic or locally advanced unresectable Human Epidermal Growth Factor (HER2)-negative breast cancer (by National Comprehensive Cancer Network (NCCN) criteria). Triple-negative breast cancer tumors will require confirmation of AR positivity at screening. Participants will have had no more than one line of previous chemotherapy in non-curative setting; subjects with metastatic progression within 1 year following completion of curative-intent chemotherapy are eligible if they have not received any additional lines of systemic therapy in the non-curative setting.

Women who meet all of the study inclusion criteria, none of the study exclusion criteria, and agree to participate will receive a combination of the following:

  • Intravenous nivolumab 240mg, every 2 weeks until progression or unacceptable toxicity
  • Intravenous ipilimumab 1mg/kg, every 6 weeks until progression or unacceptable toxicity
  • Oral bicalutamide 150mg, daily until progression or unacceptable toxicity

Participants are to be treated for up to 24 months. Patients who have ongoing response will discontinue ipilimumab and nivolumab after 24 months, but at the discretion of the investigator may continue bicalutamide, and will continue assessments as per standard of care. Any patient who subsequently progresses will have the option to resume treatment upon disease progression.

Primary Outcome Measures :
  1. iRECIST Clinical Benefit Rate (the number of patients with objective response or ongoing stable disease at week 24 using iRECIST guidelines) [ Time Frame: 24 weeks ]
    To assess the 24-week clinical benefit rate of nivolumab combined with bicalutamide and ipilimumab in advanced HER2-negative breast cancers assessed by radiographic criteria (computed tomography (CT) scan or magnetic resonance imaging (MRI) according to iRECIST criteria.

Secondary Outcome Measures :
  1. Assess best overall objective response rate (proportion of patients who achieve a complete or partial response) [ Time Frame: 24 months ]
    Best overall objective response rate will be assessed by radiographic criteria from CT or MRI scans and will be based on RECIST 1.1 and iRECIST criteria

  2. Duration of progression free survival [ Time Frame: From first patient enrolled through last patient's progression or 24 months following last patient enrolled, whichever comes first. ]
    Average length of time between study entry and disease progression or death

  3. Overall survival rate [ Time Frame: 24 months. ]
    Number of patients who are alive

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Gender Based Eligibility:   Yes
Gender Eligibility Description:   Females, aged 18 or older

Inclusion Criteria:

  • ECOG performance status of 0-1;
  • Metastatic or locally advanced unresectable HER2-negative breast cancer (by NCCN criteria);
  • Triple Negative Breast Cancer tumors will require confirmation of androgen-receptor (AR) positivity at screening (refer to laboratory manual for guidelines). Local testing permitted for eligibility if reviewed by a designated study pathologist;
  • RECIST1.1 measurable disease;
  • Participants must be willing (if clinically feasible) to provide a fresh tumor biopsy (or archived tissue). For archived tissue, a tissue block from the most recent biopsy is acceptable if no intervening anti-neoplastic therapies have been administered since the time of biopsy.
  • Previous systemic chemotherapy: no greater than one line of previous chemotherapy in non-curative setting; subjects with metastatic progression within 1 year following completion of curative-intent chemotherapy are eligible if they have not received any additional lines of systemic therapy in the non-curative setting.
  • Participants must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal patient care.
  • Participants must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests, tumor biopsies, and other requirements of the study
