Abstract
- This report describes the rationale, purpose and design of A011801 (CompassHER2 RD), an ongoing prospective, multicenter, Phase III randomized trial. Eligible patients in the United States (US) and Canada with high-risk (defined as ER-negative and/or node-positive) HER2-positive (HER2+) residual disease (RD) after a predefined course of neoadjuvant chemotherapy and HER2-directed treatment are randomized 1:1 to adjuvant T-DM1 and placebo, versus T-DM1 and tucatinib. Patients have also received adjuvant radiotherapy and/or endocrine therapy, if indicated per standard of care guidelines. The primary objective of the trial is to determine if the invasive disease-free survival (iDFS) with T-DM1 plus tucatinib is superior to iDFS with T-DM1 plus placebo; other outcomes of interest include overall survival (OS), breast cancer-free survival (BCFS), distant recurrence-free survival (DRFS), brain metastases-free survival (BMFS) and disease-free survival (DFS). Correlative biomarker, quality of life (QoL) and pharmacokinetic (PK) end points are also evaluated.Lay abstract In this research study (A011801; CompassHER2 RD), patients with early stage HER2-positive breast cancer who already received treatment with chemotherapy and anti-HER2 targeted therapies followed by surgery are mainly enrolled. If cancer is still present in the breast and/or lymph nodes at the time of surgery, there is a higher risk of a recurrence in the future, and enrollment on A011801 is an option. Usually, if there is tumor remaining after chemotherapy and anti-HER2 targeted therapies, the main treatment is the use of an FDA-approved intravenous drug called T-DM1. Additional treatment may also include radiotherapy and/or medications to block the activity of estrogen. The usual treatment approach reduces the likelihood of breast cancer recurring in the future. This study has been performed to answer the following question: Is the combination of T-DM1 and a newer drug tucatinib better than usual treatment with T-DM1 alone at preventing cancer from returning? Study participants will receive treatment with T-DM1 and placebo (a pill that looks like the study drug but contains no medication) or T-DM1 and tucatinib, for up to 14 cycles, unless their breast cancer returns or the side effects become too severe. Research bloods are taken on study along with standard blood work, and we also request a stored tumor sample from the original biopsy and from the breast cancer surgery for research purposes. Optional Quality of Life Questionnaires are also included in the trial. After the study, participants finish T-DM1 and placebo, or T-DM1 and tucatinib, and their doctor will continue to follow their condition with clinic visits every 6 months for 10 years and watch for side effects and for signs of breast cancer recurring.
