- Registration Number
- NCT04893109
- Lead Sponsor
- Dana-Farber Cancer Institute
- Brief Summary
This research study is studying how well newly diagnosed breast cancer that has tested positive for a protein called HER2 responds using one of two different combination of HER2-directed therapies as a treatment after surgery.
The name of the study drugs involved are:
* Trastuzumab-emtansine (T-DM1, Kadcyla)
* Trastuzumab SC (Herceptin Hylecta)
* Paclitaxel
- Detailed Description
This is a randomized phase II adjuvant study for women and men with Stage I HER2-positive invasive breast cancer. Participants will be randomized into one of two treatment arms in this study and receive:
* Arm 1: trastuzumab-emtansine (T-DM1, Kadcyla) and trastuzumab SC (Herceptin Hylecta)
* Arm 2: paclitaxel and trastuzumab SC (Herceptin Hylecta) This research study is looking to see if the study drug T-DM1 followed by trastuzumab SC will have less side-effects than traditional HER2-positive breast cancer treatment of trastuzumab and paclitaxel.The study is also looking to learn about the long-term benefits and disease-free survival of participants who are treated with T-DM1 followed by trastuzumab SC.
T-DM1 is an antibody-drug conjugate; it is made up of an antibody (trastuzumab) linked to a cytotoxic drug, DM1 (chemotherapy). T-DM1 functions as a targeted cancer therapy because it targets HER2-positive breast cancer cells directly, limiting exposure of the rest of the body to chemotherapy. More specifically, the trastuzumab in T-DM1 first binds to the HER2 protein on the surface of the breast cancer cells and the DM1 then enters the cells and can cause them to die, preventing tumor growth. The FDA (the U.S. Food and Drug Administration) has not approved T-DM1 for use on its own in patients with stage I, II, or III breast cancer. However, it has been approved for use in (a) advanced or metastatic, previously treated breast cancer and (b) in some patients receiving postoperative treatment after preoperative chemotherapy and surgery have been completed.
Trastuzumab SC is a subcutaneous form of trastuzumab.Trastuzumab is a monoclonal antibody, which are disease-fighting proteins made by cloned immune cells. Paclitaxel and trastuzumab are considered a standard-of-care regimen in early breast cancer. Trastuzumab is FDA-approved to be administered as an IV (intravenous) or subcutaneous (muscular injection).
The research study procedures include screening for eligibility and study treatment including laboratory evaluations and follow up visits.
Participants will receive study treatment for a year in total and will be followed for 5 years after treatment.
It is expected that about 500 people will take part in this research study.
Genentech is supporting this research study by providing funding for the study and supplying trastuzumab-emtansine (T-DM1) and trastuzumab SC (subcutaneous).
Recruitment & Eligibility
- Status

- Sex
- All
- Target Recruitment
- 500
-
Patients must have HER2-positive Stage I histologically confirmed invasive carcinoma of the breast. Patients must have node-negative (N0) or micrometastases (N1mic) breast cancer according to the AJCC 8th edition anatomic staging table.
- If the patient has had a negative sentinel node biopsy, then no further axillary dissection is required, and the patient is determined to be node-negative. If an axillary dissection without sentinel lymph node biopsy is performed to determine nodal status, at least six axillary lymph nodes must be removed and analyzed, and determined to be negative, for the patient to be considered node-negative. Axillary nodes with single cells or tumor clusters ≤ 0.2 mm by either H&E or immunohistochemistry (IHC) will be considered node-negative.
- Any axillary lymph node with tumor clusters between 0.02 and 0.2 cm is considered a micrometastasis. Patients with a micrometastasis are eligible. An axillary dissection is not required to be performed in patients with a micrometastasis found by sentinel node evaluation. In cases where the specific pathologic size of lymph node involvement is subject to interpretation, the principal investigator will make the final determination as to eligibility. The investigator must document approval in the patient medical record.
- Patients who have an area of a T1aN0, ER+ (defined as >10%), HER2-negative cancer in addition to their primary HER2-positive tumor are eligible.
-
HER2-positive by ASCO CAP 2018 guidelines, confirmed by central testing. NOTE: HER-2 status must be confirmed to be positive by central review by NeoGenomics prior to patient starting protocol therapy. Patients previously having had HER2 immunohistochemical testing by NeoGenomics do not need to undergo retesting for central confirmation of HER2 status.
NOTE: DCIS components will not be counted in the determination of HER2 status
-
ER/PR determination is required. ER and PR assays should be performed by immunohistochemical methods according to the local institution standard protocol.
-
Bilateral breast cancers that individually meet eligibility criteria are allowed.
-
Patients with multifocal or multicentric disease are eligible, as long as each tumor individually meets eligibility criteria. Central confirmation is needed for any site of disease that is tested to be HER2-positive by local testing (unless testing was previously done by NeoGenomics).
-
Patients with a history of ipsilateral DCIS are eligible if they were treated with wide excision alone, without radiation therapy, or treated with a mastectomy for this current breast cancer. Patients with a history of contralateral DCIS are not eligible.
-
≤ 90 days between the planned treatment start date and the patient's most recent breast surgery for this breast cancer
-
≥ 18 years of age with any menopausal status.
-
ECOG Performance Status 0 or 1
-
All tumor should be removed by either a modified radical mastectomy or a segmental mastectomy (lumpectomy), with either a sentinel node biopsy or axillary dissection
- All margins should be clear of invasive cancer or DCIS (i.e. no tumor on ink). The local pathologist must document negative margins of resection in the pathology report. If all other margins are clear, a positive posterior (deep) margin is permitted, provided the surgeon documents that the excision was performed down to the pectoral fascia and all tumor has been removed. Likewise, if all other margins are clear, a positive anterior (superficial; abutting skin) margin is permitted provided the surgeon documents that all tumor has been removed.
-
Patients undergoing breast conservation therapy (i.e. lumpectomy) must not have any contraindications to radiation therapy. Radiation to the conserved breast is required.
-
Patients may have received up to 4 weeks of tamoxifen therapy, or other hormonal therapy, for adjuvant therapy for this cancer. Patients cannot receive adjuvant hormonal therapy during protocol treatment for the first 12 weeks.
-
Prior oophorectomy for cancer prevention is allowed.
-
Patients who have undergone partial breast radiation (duration ≤ 14 days) prior to registration are eligible. Partial breast radiation must be completed prior to 2 weeks before starting protocol therapy. Patients who have undergone whole breast radiation are not eligible.
-
Patients who have participated in a window study (treatment with an investigational agent prior to surgery for ≤ 2 weeks) are eligible. Patients must have discontinued the investigational agent at least 14 days before participation.
-
Adequate bone marrow function:
- ANC ≥ 1000/mm3,

Contraceptive use must be continued for the duration of the study treatment and for 7 months after the last dose of study treatment. Hormonal birth control methods are not permitted.
-
Patients should have tumor tissue available, and a tissue block of sufficient size to make 15 slides, which must be sent to DFCI for correlative research. If a tissue block is unavailable, sites may send one H&E-stained slide and 15 unstained sections of paraffin-embedded tissue on uncharged slides. Slide sections should be 4-5 microns in thickness. It is also acceptable to submit 2 cores from a block of invasive tissue using a 1.2 mm diameter coring tool. If tumor is not available, the investigator must document why tissue is not available in the patient medical record, and that efforts have been made to obtain tissue.
