Phase 2 Trial.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT01730833). This is a study registration, not published results. Lead sponsor: City of Hope Medical Center. Recruitment status: COMPLETED. Phase: PHASE2. Study type: INTERVENTIONAL. Enrollment: 63 participants (ACTUAL). Conditions: HER2-positive Breast Cancer, Recurrent Breast Cancer, Stage IIA Breast Cancer, Stage IIB Breast Cancer, Stage IIIA Breast Cancer, Stage IIIB Breast Cancer, Stage IIIC Breast Cancer, Stage IV Breast Cancer, Breast Adenocarcinoma, Inflammatory Breast Carcinoma. Interventions: BIOLOGICAL: pertuzumab; BIOLOGICAL: trastuzumab; DRUG: paclitaxel albumin-stabilized nanoparticle formulation; OTHER: laboratory biomarker analysis. Primary outcome measures: Progression Free Survival (MBC Cohort) , assessed up to 5 years; Five Year Disease-free Survival (LABC Cohort) , assessed up to 5 years. Brief summary: This phase II trial studies how well pertuzumab, trastuzumab, and paclitaxel albumin-stabilized nanoparticle formulation work in treating patients with human epidermal growth factor receptor (HER) 2-positive stage II-IV breast cancer. Monoclonal antibodies, such as pertuzumab and trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to kill tumor cells or stop them from growing. Giving pertuzumab and trastuzumab together with paclitaxel albumin-stabilized nanoparticle formulation may be a better way to block tumor growth.
