AryoTrust (Trastuzumab) for Treatment of Breast cancer and Gastric cancer

AryoTrust contains the active ingredient Trastuzumab (a monoclonal antibody). Trastuzumab attach to specific proteins or antigens and is designed to bind selectively to an antigen called human epidermal growth factor receptor 2 (HER2). HER2 is found on the surface of some cancer cells where it stimulates their growth. AryoTrust binds to HER2 and stops the growth of such cells, causing them to die.

AryoTrust is used to treat breast and gastric cancer.

it is prescribed only when:

  • You have early breast cancer, with high levels of a protein called HER2.
  • You have metastatic breast cancer with high levels of HER2. AryoTrust may be prescribed in combination with the chemotherapy medicine paclitaxel or docetaxel as the first treatment for metastatic breast cancer or it may be prescribed alone if other treatments have proved unsuccessful. AryoTrust is also used in combination with medicines called aromatase inhibitors with patients with high levels of HER2 and hormone receptor-positive metastatic breast cancer.
  • You have metastatic gastric cancer with high levels of HER2, when it is in combination with the other cancer medicines capecitabine or 5-flououracil and cisplatin.
