This phase I trial studies talimogene laherparepvec given together with ipilimumab and nivolumab before surgery in patients with triple-negative or estrogen receptor positive, HER2 negative localized breast cancer. Ipilimumab and Nivolumab are immune checkpoint inhibitors that enhance immune response towards cancer cells. Talimogene laherparepvec is a modifies human herpes virus 1 that is an oncolytic virus targeting cancer cells and makes tumor microenvironment more immunogenic to promote immune response against cancer. This study will assess the safety and efficacy of talimogene laherparepvec, ipilimumab, and nivolumab, and provide an insight for further improvement of immunotherapy in breast cancer.

Official Title

A Phase 1 Study of Ipilumumab, Nivolumab and Talimogene Laherparepvec Preoperative Treatment of Localized Breast Cancer-deleted


PRIMARY OBJECTIVES: I. To explore the safety of talimogene laherparepvec in combination with nivolumab and ipilimumab in this population assessed by the frequency and severity of adverse events (AEs) using Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.0 toxicity criteria. SECONDARY OBJECTIVES: I. Assess tumor response of talimogene laherparepvec in combination with nivolumab and ipilimumab comparing to no treatment, in subjects with localized estrogen receptor (ER) positive and triple negative infiltrating ductal breast cancer. II. Descriptively analyze the evidence of tumor necrosis and inflammatory infiltration on histopathological examination and immuno-oncological findings in tumor and peripheral blood of patients treated with talimogene laherparepvec in combination with nivolumab and ipilimumab. EXPLORATORY OBJECTIVES: I. Descriptively compare tumor response in patients whose tumors are PD-L1 positive (+) and PD-L1 negative (-) at baseline. II. Determine the baseline mutational load of patients at the start of treatment and relate it to the response to treatment. III. Determine if hormone receptor status correlates with tumor responses. IV. Determine the number of tumor infiltrating lymphocytes in patient samples at the start and at the end of treatment and relate them to tumor response. V. Analyze T-cell receptor (TCR) repertoire in tumor infiltrating lymphocytes and peripheral blood mononuclear cells. OUTLINE: Participants receive talimogene laherparepvec intratumorally on days 1, 22, and 36, nivolumab intravenously (IV) over 60 minutes on days 1, 15, 29, and 43, and ipilimumab IV over 90 minutes on days 1 and 43 in the absence of disease progression or unacceptable toxicity. After completion of study treatment, participants are followed up for 30 days.

  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1
  • Localized, palpable, biopsy proven triple negative or ER positive HER2 negative infiltrating ductal breast cancer with size > 1.5 cm by palpation, excluding breast cancer where neoadjuvant chemotherapy is indicated by current guidelines (i.e. inflammatory subtype, etc.)
  • Tumor that is palpable and injectable
  • Hemoglobin >= 9 g/dL
  • Absolute neutrophil count >= 1,500/mm3

  • Platelet count >= 100,000/mm3

  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x institutional upper limit of normal (ULN)
  • Bilirubin =< 1.5 x ULN; for subjects with documented/suspected Gilbert?s disease, bilirubin =< 3 x ULN
  • Albumin >= 2.5 g/dl
  • Prothrombin time (PT) / International normalized ratio (INR) and partial thromboplastin time (PTT) =< 1.5 x institutional upper limit of normal unless the patient is on anticoagulant therapy within 28 days prior to enrollment (if the patient is receiving anticoagulant therapy, PT, and a PTT must be within therapeutic range of intended use of anticoagulants)
  • Patients must be willing to submit blood and tissue specimens for translational medicine studies
  • Patients must be offered the opportunity to participate in specimen banking for future research
  • Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the start of study drug
  • Women must not be breastfeeding
  • Women of childbearing potential (WOCBP) must be willing to use either two adequate barrier methods or a barrier method plus a hormonal method of contraception to prevent pregnancy, or to abstain from heterosexual activity (complete abstinence) throughout the study, starting with visit 1 through 5 months after the last dose of study therapy. Approved contraceptive methods include, for example, intrauterine device, diaphragm with spermicide, cervical cap with spermicide, male condoms, female condoms with spermicide, or oral contraceptives. Spermicides alone are not an acceptable method of contraception. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
  • Male patients must agree to use an adequate method of contraception, or to abstain from heterosexual activity (complete abstinence) starting with the first dose of study drug through 7 months after the last dose of study therapy
