A clinical study to compare the efficacy, safety and immunogencity of two formulations of trastuzumab in women with HER2 Positive Early breast cancer.
- Conditions
- Malignant neoplasm of breast of unspecified site,
- Registration Number
- CTRI/2019/01/017029
- Lead Sponsor
- Tanvex Biologics Corp
- Brief Summary
This is a randomized, double-blinded, parallel group, equivalence, multicenter Phase III study. The purpose of this study is to compare the research medicine TX05 with the medicine Herceptin® on how effective they are and how well are tolerated, to find out which one is better for treating HER2+ EBC. TX05 has been designed to be a “biosimilar productâ€, which means, TX05 has the same active ingredient as Herceptin®. The active ingredient is called trastuzumab, which blocks HER2 protein. Thus, similar effects as Herceptin® are expected in patients taking TX05. However this has not yet been proven. The study will also measure the amount of TX05 or Herceptin® in your body and whether or not your body makes antibodies against TX05 or Herceptin®. Antibodies against TX05 could reduce the amount of the TX05 in the blood and its effects on your cancer. Herceptin® is approved for use by Drugs Controller General of India (DCGI), the health authority that gives approval for new medicines to be prescribed in India.
