Welcome. There was a study with Cisplatin combined with or without
Erbitux RTOG 05-22, which MSKCC mentions that combining the two did not prove posituve, if I understand it right. They also mention in their letter to the Journal of Clinical Oncology, posted below, that they recommend that
Erbitux should not replace Cisplatin, outside clinical trials, as mono tretament anytime soon, until the direct comparison in RTOG 1016 phase III study is complete.
ECOG-E1308 is using Induction chemo, and substituting platinum based chemo with
Erbitux for CRT. Dana Farber has a phase II study, NCT01221753, with Induction chemo, and low dose carboplatin plus
Erbitux or full dose Carboplatin with
Erbitux, I guess depending on Induction results.
I hope this helps.
