Testing Trastuzumab and Pertuzumab in Patients With Higher Than Normal Copies of the HER2 Gene Found in Their Tumors (MATCH - Subprotocol J)

Summary

This phase II MATCH treatment trial tests how well trastuzumab and pertuzumab work in treating patients with HER2-amplified non-breast, non-gastric/gastroesophageal junction, and non-colorectal cancers. Pertuzumab and trastuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When pertuzumab or trastuzumab attach to HER2, 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. Trastuzumab is approved for the treatment of certain types of HER2-amplified cancers such as breast and gastric cancers. Research has shown that treatment with two anti-HER2 therapies in combination may be more effective at treating HER2-positive patients than giving one anti-HER2 therapy alone. Giving trastuzumab and pertuzumab in combination may be effective at treating patients with HER2-amplified cancers that aren't breast, gastric, or colorectal.
