In the ASPECCT final analysis, panitumumab remained non-inferior to cetuximab for overall survival (OS).
Patients who developed hypomagnesaemia had longer median OS versus those who did not.
For panitumumab, OS was longer for those with prior bevacizumab therapy versus those without.
OS/progression-free survival improvement correlated with worse skin toxicity for either anti-epidermal growth factor receptor therapy.
