Aug. 6, 2013 — Cancer drugs known as ErbB inhibitors have shown great success in treating many patients with lung, breast, colon and other types of cancer. However, ErbB drug resistance means that many other patients do not respond, and even among those who do, tumors commonly come back.
A new study from MIT reveals that much of this resistance develops because a protein called AXL helps cancer cells to circumvent the effects of ErbB inhibitors, allowing them to grow unchecked. The findings suggest that combining drugs that target AXL and ErbB receptors could offer a better way to fight tumors, says Doug Lauffenburger, the Ford Professor of Bioengineering, head of MIT's Department of Biological Engineering and an affiliate member of MIT's Koch Institute for Integrative Cancer Research.
