This research study is studying a combination of drugs as a possible treatment for breast cancer that has tested positive for a protein called HER2. The names of the study interventions involved in this study are: - Trastuzumab emtansine (also called T-DM1) - Pertuzumab
Active, not recruiting
Phase 2
| Drug | Synonyms | Arms |
|---|---|---|
| T-DM1 | Kadcyla | T-DM1 and Pertuzumab |
| Pertuzumab | Perjeta | T-DM1 and Pertuzumab |
This research study is a Phase II clinical trial. Phase II clinical trials test the safety
and effectiveness of an investigational intervention to learn whether the intervention works
in treating a specific disease. "Investigational" means that the intervention is being
studied. The FDA (the U.S. Food and Drug Administration) has not approved T-DM1 for
pre-operative use in breast cancer but it has been approved for other uses in breast cancer.
The FDA has approved pertuzumab as a pre-operative treatment.
| Name | Type | Description | Interventions |
|---|---|---|---|
| T-DM1 and Pertuzumab | Experimental | T-DM1 3.6 mg per kg of body weight via IV every 3 weeks for 6 doses and Pertuzumab loading dose of 840 mg via IV on Cycle 1 Day 1 followed by maintenance dose of 420 mg via IV every 3 weeks for 6 doses. Excision of tumor/mastectomy of biopsy residual tumor within 42 days of the last cycle of therapy. |

Inclusion Criteria:
- Patients must have HER2-positive Stage II or III histologically confirmed invasive
carcinoma of the breast. A minimum tumor size of 2 cm determined by physical exam or
imaging is required.
- HER-2 positive, confirmed by central testing (Clarient labs): IHC 3+ and/or FISH
positive based on one of the three following criteria:
- Single-probe average HER2 copy number≥6.0 signals/cell OR
- Dual-probe HER2/CEP17 <2.0 with an average HER2 copy number ≥6.0 signals/cell OR

- ER/PR determination is required.
- Bilateral breast cancers are allowed if both cancers are HER2-positive.
- Patients with multifocal or multicentric disease are eligible as long as one area
meets eligibility criteria.
- Breast imaging should include the ipsilateral axilla. For subjects with a clinically
negative axilla, a sentinel lymph node biopsy will be performed either before or after
preoperative therapy at the discretion of the subject's physicians. For subjects with
a clinically positive axilla, a needle aspiration, core biopsy or SLN procedure will
be performed to determine the presence of metastatic disease in the lymph nodes.

the direct bilirubin should be within the institutional normal range.

- Documentation of hepatitis B virus (HBV) and hepatitis C virus (HCV) serologies is
required: this includes hepatitis B surface antigen (HBsAg) and/or total hepatitis B
core antibody (HBcAb) in addition to HCV antibody testing.
- Only for patients who test positive for hep B/C virus: PTT/INR < ULN (institutional)
- Left ventricular ejection fraction (LVEF) ≥ 55%

have had a tubal ligation and for women less than 12 months after the onset of
menopause.

be willing to use one highly effective form of non-hormonal contraception or two
effective forms of non-hormonal contraception by the patient and/or partner and
continue its use for the duration of the study treatment and for 7 months after the
last dose of study treatment.
- Potent CYP3A4 inhibitors, such as ketoconazole and erythromycin, should be avoided
during the study treatment period with T-DM1.
- Excessive alcohol intake should be avoided (occasional use is permitted).
- Patients with a history of ipsilateral DCIS are eligible.
- Patients undergoing breast conservation therapy (i.e. lumpectomy) must not have any
contraindications to radiation therapy.
- Willing and able to sign informed consent.
- Willing to provide tissue for research purposes.
Exclusion Criteria:
- Pregnant or nursing women due to the teratogenic potential of the study drugs.
- Active, unresolved infection.
- Receipt of intravenous antibiotics for infection within 7 days prior to enrollment.
- Patients with active liver disease, for example, due to hepatitis B virus, hepatitis C
virus, autoimmune hepatic disorder, or sclerosing cholangitis.
- Uncontrolled hypertension (systolic >180 mm Hg and/or diastolic >100 mm Hg) or
clinically significant (i.e. active) cardiovascular disease: cerebrovascular
accident/stroke or myocardial infarction within 6 months prior to first study
medication, unstable angina, congestive heart failure (CHF) of New York Heart
Association (NYHA) Grade II or higher, or serious cardiac arrhythmia requiring
medication.
- Significant symptoms (Grade ≥2) peripheral neuropathy.
- Other concurrent serious diseases that may interfere with planned treatment, including
severe pulmonary conditions/illness, uncontrolled infections, uncontrolled diabetes.
- Any prior treatment for the current breast cancer, including chemotherapy, hormonal
therapy, radiation or experimental therapy.
