Drug Name | Trade Name | Synonyms | Drug Classes | Drug Description |
---|---|---|---|---|
Letrozole | Femara | Letrozol | Aromatase Inhibitor 3 | Femara (letrozole) is an aromatase inhibitor, which inhibits estrogen synthesis, and is approved for postmenopausal women with hormone receptor positive breast cancer (FDA.gov). |
Pertuzumab | Perjeta | 2C4 Antibody | HER2 (ERBB2) Antibody 76 | Perjeta (pertuzumab) is a monoclonal antibody that binds ERBB2 (HER2) to prevent dimerization and subsequent HER signaling, thereby resulting in apoptosis and tumor growth inhibition (PMID: 15699478). Perjeta (pertuzumab) is FDA approved in combination with Herceptin (trastuzumab) and Taxotere (docetaxel) for patients with ERBB2 (HER2)-positive breast cancer and in combination with Herceptin (trastuzumab) and chemotherapy as neoadjuvant treatment for patients with ERBB2 (HER2)-positive breast cancer (FDA.gov). |
Trastuzumab | Herceptin | Anti HER2 | HER2 (ERBB2) Antibody 76 | Herceptin (trastuzumab) is a monoclonal antibody, which binds ERBB2 (HER2) to induce tumor cellular cytotoxicity (PMID: 17611206). Herceptin (trastuzumab) is FDA approved for HER2-overexpressing (or amplification) breast cancer, gastric adenocarcinoma, and gastroesophageal junction adenocarcinoma (FDA.gov). |
Tucatinib | Tukysa | ONT-380|ARRY-380|irbinitinib | HER2 Inhibitor 42 | Tukysa (tucatinib) selectivity inhibits ERBB2 (HER2), resulting in decreased proliferation and increased apoptosis in ERBB2 (HER2) expressing tumor cells (PMID: 28053022). Tukysa (tucatinib) in combination with Herceptin (trastuzumab) and Xeloda (capecitabine) is FDA approved for use in patients with advanced unresectable or metastatic ERBB2 (HER2)-positive breast cancer, including patients with brain metastasis, who have received prior anti-HER2 therapies, and in combination with Herceptin (trastuzumab) for patients with RAS wild-type ERBB2 (HER2)-positive unresectable or metastatic colorectal cancer that has progressed following fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy (FDA.gov). |
