 (submitted: April 1, 2019)
  • Progression-free survival (PFS) [ Time Frame: within approximately 3 years ]
    PFS based on Investigator Assessment is defined as the time from randomization to the first clinical observation of disease progression or death.
  • Objective (overall) response rate (ORR) [ Time Frame: within approximately 3 years ]
    ORR is defined as the percentage of participants who achieve objective CR or PR, confirmed by second assessment

    OS is defined as the time from randomization to death
  • Duration of Response (DoR) [ Time Frame: within approximately 3 years ]
    DoR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death

Brief Title  ICMJE Study of IMMU-132 in HR+/HER2- MBC (TROPICS-02)
Official Title  ICMJE Phase 3 Study of Sacituzumab Govitecan vs Physician's Choice in Subjects With Hormonal Receptor-Positive Human Epidermal Growth Factor Receptor 2 Negative Metastatic Breast Cancer Who Have Failed at Least 2 Prior Chemotherapy Regimens
Brief Summary This is an open-label, randomized, multicenter Phase 3 study to compare the efficacy and safety of Sacituzumab Govitecan versus TPC in subjects with metastatic or locally recurrent inoperable HR+/HER2- MBC, after failure of at least 2, and no more than 4, prior chemotherapy regimens for metastatic disease.

Control Arm:

Recommended doses and schedules as per NCCN guidelines (with dose modifications if too toxic).

Eribulin; Capecitabine; Gemcitabine; Vinorelbine

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Female or male subjects aged ≥18 years at the time of signing the informed consent form
  • Documented evidence of hormone receptor-positive HER2-negative (HR+/HER2-) MBC confirmed
  • Refractory to or relapsed after at least 2, and no more than 4, prior systemic chemotherapy regimens for MBC including:
  • At least 1 prior anticancer hormonal treatment.
  • At least 1 cyclin-dependent kinase inhibitor 4/6 in the metastatic setting.
  • Eligible for one of the chemotherapy options listed in the TPC arm
  • Documented disease progression after the most recent therapy
  • Adequate bone marrow function (hemoglobin > 9 g/dL, ANC > 1,500 per mm3, platelets > 100,000 per mm3).
  • Adequate renal function: calculated creatinine clearance ≥30 mL/minute according to the Cockcroft and Gault formula

Exclusion Criteria:

  • Previous treatment with Topoisomerase 1 Inhibitors as a free form or as other formulations
  • History of significant cardiovascular disease or clinically significant ECG abnormality
  • Patients with Gilbert's disease.
  • Active infection requiring intravenous antibiotic use
  • Patients with a history of an anaphylactic reaction to irinotecan.
  • Other concurrent medical or psychiatric conditions that, in the Investigator's opinion, may be likely to confound study interpretation or prevent completion of study procedures and follow-up examinations.
