This is an international, multi-center, open-label, randomized, Phase III study in patients with metastatic TNBC refractory or relapsing after at least 2 prior chemotherapies (including a taxane) for their metastatic disease. Patients meeting eligibility will be randomized 1:1 to receive either sacituzumab govitecan or treatment of physician choice (TPC), which needs to be selected prior to randomization from one of the 4 allowed regimens. Randomization will be stratified by number of prior chemotherapies for advanced disease (2-3 vs > 3) and geographical location (North America vs Europe).

Patients will be treated until progression, unacceptable toxicity, study withdrawal, or death, whichever comes first. Tumor progression leading to treatment withdrawal will be assessed by the investigator. Starting with the initial dose of sacituzumab govitecan or TPC, CT scans (or MRI if contrast allergic) will be obtained at least every 8 weeks until the occurrence of progression of disease requiring discontinuation of further treatment.All patients, including those prematurely terminating study participation, will be followed every 4 weeks during the first year and every 8 weeks thereafter for survival follow-up.

Primary Outcome Measures:
  • Progression-Free Survival (PFS): [ Time Frame: 3 YEARS ]

Secondary Outcome Measures:
  • Overall Survival (OS): [ Time Frame: 3 YEARS ]

    OS will compared between the two treatment groups.

    PFS will be measured by an independent centralized and blinded group of radiology experts who will be assessing tumor response using RECIST 1.1 criteria. FDA definitions and guidance as described in Guidance for Industry:

  • Objective Response Rate [ Time Frame: 3 years ]
    ORR will compared between the two treatment groups.

  • Duration of Response [ Time Frame: 3 years ]
    Duration of response will compared between the two treatment groups.

  • Time to Onset of response [ Time Frame: 3 years ]
    Time to onset of response will compared between the two treatment groups.

Estimated Enrollment: 328

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Female or male patients, >18 years of age, able to understand and give written informed consent.
  • Histologically or cytologically confirmed TNBC based on the most recent analyzed biopsy or other pathology specimen. TNBC determination as per local institution as per standard guidelines.
  • Refractory to or relapsed after at least two prior standard therapeutic regimens for advanced/metastatic TNBC. Prior use of cisplatin (or carboplatin) is permitted.
  • Prior exposure to a taxane (paclitaxel or docetaxel)-based regimen in localized or advanced/metastatic setting.
  • Eligible for one of the chemotherapy options listed as TPC (Eribulin, capecitabine, gemcitabine, or vinorelbine) as per investigator assessment.
  • ECOG performance score of 0 or 1 .
  • Measurable disease by CT or MRI as per RECIST 1.1. Bone-only disease is not permitted.
  • At least 2 weeks beyond prior treatment (chemotherapy, investigational drugs including small molecular inhibitors, endocrine therapy, immunotherapy and/or radiation therapy) or major surgery, and recovered from all acute toxicities to Grade 1 or less (except alopecia and peripheral neuropathy).
  • At least 2 weeks beyond high dose systemic corticosteroids (however, low dose corticosteroids < 20 mg prednisone or equivalent daily are permitted).
  • Adequate hematology without ongoing transfusional support (hemoglobin > 9 g/dL, ANC > 1,500 per mm3, platelets > 100,000 per mm3).
  • Adequate renal and hepatic function (creatinine ≤ 2.0 x IULN, bilirubin ≤ 1.5 IULN, AST and ALT ≤ 3.0 x IULN or 5 x IULN if known liver metastases).
  • Otherwise, all toxicity at study entry < Grade 1 by NCI CTCAE v4.00 (Patients with ≤ Grade 2 neuropathy are eligible).

  • Patients with Gilbert's disease.
  • Presence of bulky disease (defined as any single mass > 7 cm in its greatest dimension). Patients with a mass over 7 cm, but otherwise eligible, may be considered for enrollment after discussion and approval with the medical monitor.
  • Patients with active ≥ grade 2 anorexia, nausea or vomiting, and/or signs of intestinal obstruction.
  • Patients with non-melanoma skin cancer or carcinoma in situ of the cervix are eligible, while patients with other prior malignancies must have had at least a 3-year disease-free interval.
