Brief Summary:
This phase II trial studies how well mirvetuximab soravtansine works as first line in treating patients with triple negative breast cancer. Drugs used in chemotherapy, such as mirvetuximab soravtansine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Detailed Description:

PRIMARY OBJECTIVES:

  • I. Determine if mirvetuximab soravtansine as a single agent is likely to induce response in at least 20% of patients with metastatic folate receptor (FR) alpha+ triple negative breast cancer (TNBC).
  • II. Determine if mirvetuximab soravtansine as a single agent in the neoadjuvant setting will improve rates of excellent pathologic response (pathologic complete response [pCR]/residual cancer burden [RCB]-0 or RCB-I) from 5% to 20% in patients with high risk, chemotherapy insensitive, FRalpha+ TNBC.

SECONDARY OBJECTIVES:

  • I. Determine the radiographic response rate as measured by ultrasound and/ or magnetic resonance imaging (MRI) (partial response + complete clinical response) for mirvetuximab soravtansine in chemotherapy insensitive, FRalpha

    + localized TNBC or using Response Evaluation Criteria in Solid Tumors (RECIST) criteria in patients with FRalpha+ advanced TNBC.

  • II. Determine toxicity of 4 cycles of mirvetuximab soravtansine given in the neoadjuvant setting following anthracycline based therapy (Cohort B) and unrestricted cycles in patients receiving therapy in the advanced/metastatic setting (Cohort A).
  • III. Determine disease free survival (DFS) at 3 years for patients treated with mirvetuximab soravtansine given in the neoadjuvant setting; progression free survival (PFS), duration of response (DOR) and overall survival at 3 years (overall survival [OS] at 3 years) in patients receiving therapy for advanced/ metastatic TNBC.
  • IV. Compare disease response (as measured by pCR/RCB-I) in patients with FRalpha+ chemotherapy resistant disease treated on clinical trial with mirvetuximab soravtansine in the neoadjuvant setting to those with similar molecular features who receive standard taxane-based chemotherapy as the second phase of their NACT.

Primary Outcome Measures :
  1. Response rate [ Time Frame: Up to 1 year ]

Secondary Outcome Measures :
  1. Radiographic response rate (partial response + complete clinical response) [ Time Frame: Up to 1 year ]
    Will be estimated, and reported with a 95% confidence interval (CI).

  2. Incidence of adverse events [ Time Frame: Up to 1 year ]
    Will be assessed by Common Terminology Criteria for Adverse Events version 4.0. Adverse events and serious adverse events will be summarized in order of prevalence, with the highest grade experienced by each patient reported for each adverse event.

  3. Disease free survival [ Time Frame: Up to 1 year ]
    Will be estimated using the Kaplan-Meier method from the date of enrollment onto this study. Will be reported with a 95% CI.

  4. Progression free survival [ Time Frame: Up to 1 year ]
    Will be estimated using the Kaplan-Meier method from the date of enrollment onto this study. Will be reported with a 95% CI.

  5. Overall survival [ Time Frame: Up to 1 year ]
    Will be estimated using the Kaplan-Meier method from the date of enrollment onto this study. Will be reported with a 95% CI.

  6. Duration of response [ Time Frame: From the date of confirmed response to the date of disease progression (as measured by Response Evaluation Criteria in Solid Tumors) or discontinuation of study drug due to toxicity, assessed up to 1 year ]
  7. Disease response (as measured by pathologic complete response [pCR]/residual cancer burden [RCB]-I (Cohort B) [ Time Frame: Up to 1 year ]
    Will be compared to those with similar molecular features who receive standard taxane-based chemotherapy while enrolled in the ARTEMIS trial. A one-sided Fisher's exact test will be used to compare the pCR rate (RCB=0 or I) between the standard therapy patients and the mirvetuximab soravtansine treated patients.

  • (For Cohort A) Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST). (For cohort B) Clinical or radiologic primary tumor size of at least 1.5 cm prior to enrollment onto protocol 2014-0185 (ARTEMIS). Primary tumor of at least 1.0 cm or evidence of continued lymph node involvement by imaging (ultrasound or magnetic resonance imaging [MRI]) after adriamycin-based neoadjuvant therapy
