In the more than 9,000 patients treated with nimotuzumab worldwide to date in numerous cancer indications, there have been very few reports of Grade 3/4 acneform rash and rare occurrences of the other severe toxicities frequently reported with other EGFR-targeting agents.  The absence of acneform rash to date and the rare instances of any of the other debilitating side-effects holds the potential for nimotuzumab to become best-in-class for this important family of EGFR-targeting agents.
