Neoadjuvant Cetuximab in HNSCC Combined With Curative Surgery (CHIRON)
Neoadjuvant Cetuximab Monotherapy Followed by Surgery in Squamous Cell Carcinoma of Head and Neck: Phase I/II Study
Primary diagnose HNSCC carcinoma patients eligible for curative surgery will be proposed the addition of 2 or 3 neoadjuvant cetuximab infusions. The main objective is to reduce to a minimal delay the time elapsing between last infusion and surgery.
Iterative biomarkers will be taken at 6 time points permitting to investigate expression gen profile and protein mutation.
Studieöversikt
Detaljerad beskrivning
This is a Phase I/II trial of neoadjuvant cetuximab monotherapy in the preoperative treatment of patients with operable HNSCC. It is a monocenter study (St-Luc university Hospital, Université catholique de Louvain, Brussels).
This part of the trial will determine the safe minimum delay between the neoadjuvant cetuximab infusion and surgery. The aim is to investigate if cetuximab given 24 hours before surgery is safe.
Patients will receive cetuximab with a loading dose of 400 mg/m2 for the first administration followed by 250 mg/m2/week at the second and third administrations, if applicable. The delay between the last administration of cetuximab and surgery will be progressively reduced (Figure 1).
Five levels are pre-defined before final administration of 3 preoperative doses of cetuximab with a 24-hour delay between the last dose of cetuximab and surgery.
Level I: 10-12 days delay between the second cetuximab infusion and surgery (total of 2 doses pre-op) Level II: 6-8 days delay between the second cetuximab infusion and surgery (total of 2 doses pre-op) Level III: 3-4 days delay between the second cetuximab infusion and surgery (total of 2 doses pre-op) Level IV: 3-4 days delay between the third cetuximab infusion and surgery (total of 3 doses pre-op) Level V: 24-hour delay between the third cetuximab dose and surgery (total of 3 doses pre-op) The cohort size is 3 patients per level, extended to 6 patients if one "limiting toxicity" is observed. Decision rules are the same than as in any classic 3+3 phase 1design (Figure 2).
"Limiting toxicity" is defined as (i) any life-threatening (grade 4) surgical complication or (ii) an unexpected surgical grade 3 toxicity. Unexpected toxicity will be determined by the safety committee after careful review of the patient file.
The safety committee will consist of the surgical team of UCL Saint-Luc, one external surgeon, one representative from Merck and the study coordinators.
Patients treated at level V will be evaluated like patients in the phase II part.

Övrig: I-1
This is a phase I/II trial. PhaseI: The delay between the last administration of cetuximab and surgery will be progressively reduced. Five delay schedules are pre-defined before final administration of 3 preoperative doses of cetuximab with a 24-hour delay between the last dose of cetuximab and surgery. The cohort size is 3 patients per delay schedule, extended to 6 patients if one "limiting toxicity" is observed. Phase II: will proceed if delay schedule V is safe. The patients included in delay schedule V of the Phase I part of the study will be involved in the phase II analysis. Recruitment of a total of 12 patients (3-6 of delay schedule V in phase I plus an additional 3-9 patients). |
