Clinical trial for Anatomic Stage I Breast Cancer AJCC v8

Official title ShortStop-HER2: 12 Months vs. 6 Months of HER2-targeted Medications for People With HER2+ Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Trastuzumab

ClinicalTrials.gov ID: NCT06876714

What this study is testing

What is Trastuzumab (Herceptin)?

An investigational biological medicine being studied for early stage HER2-positive breast cancer after surgery and chemotherapy. It is designed to bind to the HER2 protein on cancer cells and block signals that promote tumor growth.

Also referred to as Herceptin.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see if 6 months of HER2‑targeted therapy is as good as or better than 12 months for people who had no cancer left after pre‑surgery chemo with trastuzumab.
Who it's for
Women or men with early‑stage HER2‑positive breast cancer who had a pathologic complete response after neoadjuvant chemotherapy with trastuzumab.
What's involved
Participants will receive either 6 or 12 months of HER2‑targeted drugs (trastuzumab and possibly pertuzumab) and will have regular clinic visits and tests to monitor safety and effectiveness.
Time commitment
The trial lasts up to 12 months of treatment, with follow‑up visits every few weeks during treatment and periodic visits afterward to check progress.

Who can take part

Ages 18 and older

You may be able to join if

  • Patients (females and males) with clinical stage T1c-T3 (or Tx) and nodal stage N0-N1 (except T3N1 tumors, which are not eligible)
  • Patients must have no residual invasive disease in the breast or lymph nodes after the completion of neoadjuvant therapy.
  • HER2+ by American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines. Central pathology review is not required.

Who can join
  • Patients (females and males) with clinical stage T1c-T3 (or Tx) and nodal stage N0-N1 (except T3N1 tumors, which are not eligible)
  • Patients must have no residual invasive disease in the breast or lymph nodes after the completion of neoadjuvant therapy. Residual ductal carcinoma in situ (DCIS) is allowed.
  • HER2+ by American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines. Central pathology review is not required.
  • Known hormone receptor status as defined by ASCO/CAP guidelines. Estrogen receptor (ER) and progesterone receptor (PR) of any values are allowed.
  • If invasive disease was present in both breasts, participation in the study is permitted as long as the eligibility criteria are met for both tumors/breasts (including the requirement that at least one biopsied site on...
  • Age ≥ 18 years
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2
  • Patients must have received neoadjuvant chemotherapy in combination with trastuzumab with or without pertuzumab for a minimum of 12 weeks. All chemotherapy must have been completed preoperatively
  • Patient must complete a minimum of 12 weeks of coverage with trastuzumab and a maximum of 24 weeks in the combined neoadjuvant and adjuvant setting prior to trial registration.
  • Administration of endocrine therapy for treatment of this breast cancer is allowed prior to trial registration.
  • No use of investigational anti-cancer agents at time of registration
  • Patient must register within 14 weeks of final surgery
  • Breast surgery: Total mastectomy with grossly negative margins (in the opinion of the surgeon there is no disease grossly at the margins) or breast-conserving surgery with histologically negative margins (no ink on...
  • Lymph node surgery: Lymph node surgery must have been performed and can include sentinel lymph node biopsy, targeted axillary dissection, or axillary dissection, at the discretion of the breast surgeon
  • Adequate radiation: Patients who completed breast-conserving surgery (i.e. lumpectomy) must have received or plan to receive adjuvant radiation.
  • Adjuvant radiation can be given on study, and in this case is encouraged to be given concurrently with adjuvant HER2-directed therapy, per investigator discretion
  • Targeting of the regional nodal basins will be at treating investigator discretion
  • Not pregnant and not nursing, because this study involves agents with known teratogenic potential.
  • Adequate hepatic, renal and bone marrow function to receive adjuvant HER2-directed therapy in the opinion of the treating investigator. There are no specific required laboratory values for eligibility
  • No stage IV (metastatic) breast cancer
  • Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or how well it works assessment of the investigational regimen are eligible for...
  • No history of any prior (ipsilateral [ipsi-] or contralateral) invasive breast cancer. Prior DCIS is allowed
  • No evidence of recurrent disease following preoperative therapy and surgery
  • Patients living with HIV who are healthy and deemed by their medical team to have a low risk of AIDS-related illnesses are included in this trial.
  • Patients with inadequate cardiac function on most recent assessment of left ventricular ejection fraction (LVEF) are not eligible for this trial.
  • No history of grade 3 or 4 toxicity related to trastuzumab. If pertuzumab is planned to be given on trial, patient must also have no history of grade 3-4 toxicity related to pertuzumab
  • No contraindication to receipt of further HER2-directed therapy
  • No patients with severe, uncontrolled systemic disease that may interfere with planned trial therapy.

The study team makes the final eligibility decision.
