Ado-trastuzumab emtansine, also known as T-DM1, is a groundbreaking antibody-drug conjugate (ADC) utilized in targeted cancer therapies, particularly for HER2-positive breast cancer. As a research-grade biosimilar, it enables cost-effective and high-quality options for laboratory investigations, drug development, and preclinical testing.
T-DM1 combines trastuzumab, a monoclonal antibody targeting HER2 (human epidermal growth factor receptor 2), with DM1, a cytotoxic agent. This unique mechanism ensures selective delivery of the drug to HER2-positive cancer cells, sparing healthy tissues and reducing systemic toxicity. To explore detailed studies on HER2 biology, visit resources such as National Cancer Institute (NCI) and PubMed Central (PMC).
Mechanism of Action
T-DM1 exerts its therapeutic effects by binding to HER2-overexpressing cells. Upon binding, the conjugate is internalized and undergoes proteolytic degradation, releasing DM1 to inhibit microtubule assembly and induce apoptosis in cancer cells. You can learn more about ADC mechanisms from NIH’s National Library of Medicine and FDA’s biosimilar guidelines.
