Problems solved by technology

Clinically, simultaneous inhibition of wild-type EGFR can lead to rashes and diarrhea in patients, which limits the dose of second-generation EGFR inhibitors, so that the plasma concentration of the drug is not enough to inhibit T790M, making the clinical effectiveness of this class of drugs subject to greater restrictions
