EA1181 (CompassHER2-pCR): Preoperative THP and postoperative HP in patients who achieve a pathologic complete response.

Protocol Number:
NCTNEA1181
Phase:
NULL
Physician:
Antonio Wolff
Sites:
Johns Hopkins Kimmel Cancer Center in Baltimore
Sibley Memorial Hospital
Purpose:
This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When these drugs attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment.

For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral loadExclusion Criteria:•Patient must not have a history of any prior (ipsilateral or contralateral) invasive breast cancer?One exception: a patient with a history of T1N0 triple negative breast cancer diagnosed more than 10 years earlier, who remains disease free is eligible•Patient must not have prior ipsilateral ductal breast carcinoma in situ (DCIS). Patients with prior lobular breast carcinoma in situ (LCIS), atypical hyperplasia, other high risk benign lesions or contralateral DCIS (without evidence of microinvasion) are eligible?NOTE: Patients currently receiving endocrine therapy for prior contralateral DCIS are eligible•Patient must not have stage IV (metastatic) breast cancer?Staging studies (computed tomography [CT] chest/abdomen/pelvis and a bone scan or positron emission tomography [PET]-CT scan) are required for stage III disease or those with abnormal baseline liver function tests (LFTs), symptoms (e.g. new bone pain) or abnormal physical exam findings •Patient must not have T4 and/or N3 disease, including inflammatory breast cancer•Patient must not have any prior treatment for the current breast cancer, including surgery, chemotherapy, hormonal therapy, radiation or experimental therapy•Patients must not have greater than grade 1 peripheral neuropathy of any etiology•Patient must not have a concurrent serious medical condition that would preclude completion of study therapy.
