NCT04266249 ↗ CompassHER2-pCR: Decreasing Chemotherapy for Breast Cancer Patients After Pre-surgery Chemo and Targeted Therapy Recruiting National Cancer Institute (NCI) Phase 2 2020-02-11 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.

NCT00551421 ↗ Pertuzumab and Cetuximab in Treating Patients With Previously Treated Locally Advanced or Metastatic Colorectal Cancer Completed National Cancer Institute (NCI) Phase 1/Phase 2 2007-10-01 Monoclonal antibodies, such as pertuzumab and cetuximab, 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. Giving pertuzumab together with cetuximab may kill more tumor cells. This phase I/II trial is studying the side effects and best dose of pertuzumab when given together with cetuximab and to see how well they work in treating patients with previously treated locally advanced or metastatic colorectal cancer
NCT00567190 ↗ A Study to Evaluate Pertuzumab + Trastuzumab + Docetaxel vs. Placebo + Trastuzumab + Docetaxel in Previously Untreated HER2-Positive Metastatic Breast Cancer Completed Hoffmann-La Roche Phase 3 2008-02-12 This study was a Phase III, randomized, double-blind, placebo-controlled, multicenter international clinical trial conducted to investigate the use of pertuzumab in combination with trastuzumab and docetaxel as first-line treatment for participants with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC). Participants could have received one prior hormonal treatment for MBC. Participants may have received systemic breast cancer treatment in the neo-adjuvant or adjuvant setting, provided that the participant had experienced a disease-free interval (DFI) of greater than or equal to (≥)12 months from completion of adjuvant systemic treatment (excluding hormonal therapy) to metastatic diagnosis. Participants may have received trastuzumab and/or a taxane during the neo-adjuvant or adjuvant treatment. Participants were randomized in 1:1 ratio to receive either pertuzumab or placebo, along with trastuzumab and docetaxel once every 3 weeks (q3w), during the treatment phase of the study until investigator-assessed radiographic or clinical progressive disease, unmanageable toxicity, or study termination. Participants in the Placebo arm were not allowed to receive open-label pertuzumab after discontinuation from study treatment. However, if any analysis of overall survival had met the predefined criteria for statistical significance, participants in the Placebo arm still on treatment were offered the option to receive open-label pertuzumab in addition to other study medications.
