This study is an open label, randomized, multicenter trial of MM-302 plus trastuzumab. The trial is designed to demonstrate whether MM-302 plus trastuzumab is more effective than the chemotherapy of physician's choice (CPC) plus trastuzumab in locally advanced/metastatic HER2-positive breast cancer patients who have received prior treatment with trastuzumab in any setting and who have either progressed or are intolerant to each of pertuzumab and ado-trastuzumab emtansine in the metastatic or locally advanced setting. Patients must not have been previously treated with an anthracycline in any setting.

Primary Outcome Measures:
  • Independently assessed progression-free survival according to modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Locally assessed progression-free survival according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]
  • Overall Survival [ Time Frame: Approximately 3 years ] [ Designated as safety issue: No ]
  • Time to Treatment Failure [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]
  • Objective Response Rate based on independent and investigator review of tumor assessments [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]
  • Duration of Response (DoR) based on independent and investigator review of tumor assessments [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]
  • Safety [ Time Frame: Approximately 2 years ] [ Designated as safety issue: Yes ]
    We will look specifically at the Number of Participants with Adverse Events related to MM-302 as compared to the control arm

  • Pharmacokinetic exposure of MM-302 [ Time Frame: Approximately 2 years ] [ Designated as safety issue: No ]
    Area Under Curve (AUC) Time Frame: Cycles 1 and 2 - pre-infusion, post-infusion, and 168 hours post-dose. An optional timepoint at 8-96 hours post infusion is included during both cycles as well.

Inclusion Criteria:

  • Patients must have histologically or cytologically confirmed invasive cancer of the breast
  • Patients must have documented locally advanced/metastatic disease, defined by the investigator, which is not amenable to resection with curative intent.
  • Patients must have HER2-positive breast cancer as defined by ASCO/CAP 2013 guidelines that is confirmed by a Sponsor-designated central laboratory
  • Patients must have progressed on, or be intolerant to pertuzumab in the LABC/MBC setting
  • Patients must have progressed on, or be intolerant to ado-trastuzumab emtansine in the LABC/MBC setting
  • Patients must have been previously treated with trastuzumab in any setting (which may have been previously administered with or without pertuzumab)
  • ECOG Performance Status of 0 or 1

Exclusion Criteria:

  • Patients who have previously been treated with doxorubicin, liposomal doxorubicin, epirubicin, mitoxantrone, or any other anthracycline derivative
  • Subjects with central nervous system (CNS) metastases, unless they have been treated and are stable without symptoms for 4 weeks after completion of treatment and must be off steroids for at least 4 weeks prior to enrollment
  • Patients with any class of New York Heart Association (NYHA) CHF or heart failure with preserved ejection fraction (HFPEF)
  • Patients with a history of known coronary artery disease or a myocardial infarction within the last 12 months
  • Patients with a known history of serious cardiac arrhythmias requiring treatment (exception: controlled atrial fibrillation, paroxysmal supraventricular tachycardia)
  • Patients who previously discontinued trastuzumab due to unacceptable cardiac toxicity
  • Patients with a history of LVEF decline to below 50% during or after prior trastuzumab/lapatinib or other HER2 directed therapy.
