Herceptin is used for breast cancer, specifically HER2-positive early breast cancer and HER2-positive metastatic or locally advanced cancer. It is being studied in breast neoplasms and other neoplasms. Herceptin is an investigational drug in clinical development, not yet approved.
Herceptin targets ERBB2, also known as HER2, and acts as an inhibitor of this receptor. By inhibiting ERBB2, Herceptin interferes with signaling pathways that drive cancer cell growth in HER2-positive tumors.
Herceptin is developed by Roche Holding AG, traded as RHHBY. Roche is conducting clinical trials to evaluate the drug's safety and efficacy in breast cancer patients.
Herceptin is in Phase 3 clinical development. It has completed Phase 1, Phase 2, and Phase 3 trials. Herceptin is investigational and not yet approved for any indication.
Herceptin has completed four clinical trials: NCT00800436, a Phase 1 dose-finding study in healthy volunteers and HER2-positive females; NCT01401166, a Phase 2 preference study; NCT01566721, a Phase 3 safety study; and NCT02721641, a Phase 3 continuation study. All trials are completed.
Yes, Herceptin is also known as Trastuzumab and Trastuzumab SC. These names refer to the same drug, with Trastuzumab SC indicating the subcutaneous formulation.
