Brief Summary:

The goal of this clinical research study is to learn if mirvetuximab soravtansine can help to control either newly diagnosed or metastatic (has spread) triple-negative breast cancer (TNBC).

Mirvetuximab soravtansine is designed to stop cell growth by blocking certain proteins in the cancer cells related to the mineral folate. This is believed to cause the cancer cells to die.

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

Inclusion Criteria:

  1. Age =/> 18 years.
  2. ECOG performance status of 0 or 1.
  3. Confirmed invasive triple-negative breast cancer defined as ER<10%; PR<10% by IHC and HER2 0-1+ by IHC or 2+, FISH < 2, gene copy number < 4.
  4. (For Cohort A) - Archived tissue available at pre-screening to confirm FR alpha+ breast cancer.
  5. (For Cohort A) Archived tissue available pre-screening to confirm FR alpha+ breast cancer. (For Cohort B) Confirmed FRalpha+ breast cancer defined as high FRalpha expression: =/>75% of cells having =/>1+ expression, or moderate FRalpha expression: 25%-74% of cells with =/>1+ expression.
  6. (For Cohort A) Measurable disease per RECIST. (For cohort B) Clinical or radiologic primary tumor size of at least 1.5cm prior to enrollment onto protocol 2014-0185 (ARTEMIS). Primary tumor of at least 1.0 cm or evidence of continued lymphnode involement by imaging (ultrasound or MRI) after Adriamycin-based neoadjuvant therapy.
  7. (For cohort B): primary tumor sample collected before NACT started (on ARTEMIS) and underwent molecular testing for integral biomarkers including immunohistochemical assessment of FRalpha.
  8. (For cohort A): no limit on prior therapies for metastatic disease. (Relapse of disease within 6 months of adjuvant or neoadjuvant chemotherapy is considered 1 line of therapy for metastatic disease). (For cohort B): received at least one dose of an anthracycline-based NACT. Patients are eligible if therapy was discontinued due to disease progression or therapy intolerance. Patients with disease progression on anthracycline-based therapy should be evaluated by the surgical team. If the patient is deemed inoperable at the time of evaluation, the patient may continue to undergo protocol therapy with a goal of reduction in tumor size to become operable. If the patient is deemed at high risk of becoming inoperable by the surgical team based upon tumor size or location, the patient will be considered ineligible for study and will be recommended to go to surgery.
  9. (For cohort B): Primary tumor size of at least 1.0 cm by imaging (ultrasound or MRI) or evidence of continued lymph node involovement by imaging (ultrasound or MRI) after Adriamycin-based neoadjuvant therapy.
  10. (For cohort B): baseline MUGA or echocardiogram showing LVEF =/> 50% within 6 weeks prior to initiation of NACT.
  11. (For both cohorts A and B): Adequate bone marrow function as shown by: • ANC =/>1.5x10^9 /L, • Platelets =/ >100x10^9 /L, • Hb >9 G/dL.
  12. (For both cohorts A and B): Adequate organ function as shown by: • Total serum bilirubin =/<2.0 mg/dL, • ALT and AST =/<2.5x ULN (=/<5x ULN in patients with liver metastases), • INR =/<2; • Serum creatinine =/<1.5x ULN; • Serum albumin >2.
  13. Signed informed consent obtained prior to any screening procedures.
  14. (For cohort A only): Time from prior therapy: a. Systemic anti-neoplastic therapy: five half-lives or four weeks, whichever is shorter. Hormonal therapy is not considered anti-neoplastic therapy. b. Radiotherapy: wide-field radiotherapy (e.g. > 30% of marrow-bearing bones) completed at least four weeks, or focal radiation completed at least two weeks, prior to starting study treatment
  15. (For cohort B only): patients must have at least 3 and no more than 5 weeks between anthracycline-based therapy and start of treatment with mirvetuximab soravtansine.

  17. (For both cohorts A and B): WCBP must have a negative pregnancy test within 3 days prior to the first dose of study treatment.

Exclusion Criteria:

  1. Pregnant or lactating women.
  2. Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable or will not be able to complete the entire study

In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of childbearing potential.

Patients with previously treated CNS metastasis (excluding carcinomatous meningitis) may participate if they are stable (without evidence of progression by imaging, using identical imaging modality at each assessment, for at least 4 weeks prior to first dose of study treatment), have no evidence of new or emerging CNS metastasis, and are not using steroids for at least 7 days prior to first dose of study treatment.
