Recent Advances in Measuring Response to Immune Checkpoint Inhibitors

In recent years, the U.S. Food and Drug Administration has approved immune checkpoint inhibitors, a class of immunotherapy, to treat 10 different types of cancer, in addition to solid tumors located anywhere in the body that have certain DNA damage and repair-related biomarkers. However, only a small percentage of patients respond to these treatments, and they can have significant side effects. Researchers are looking for biomarkers that can identify patients who are likely to respond to immune checkpoint inhibitors.

Overcoming Drug Resistance: The EGFR Enigma

Currently, anti-EGFR therapies are approved by the U.S. Food and Drug Administration for the treatment of non-small cell lung cancer, squamous cell carcinoma of the head and neck, pancreatic cancer, and colorectal cancer. Most patients receiving anti-EGFR therapies benefit from the treatment, but the challenge they face, as do patients receiving most other targeted therapies, is that their tumors ultimately develop drug resistance. So efforts are underway to develop newer anti-EGFR therapies that can circumvent resistance to existing EGFR inhibitors.
