Cetuximab Plus Radiotherapy Versus Cisplatin Plus Radiotherapy in Locally Advanced Head and Neck Cancer (CTXMAB+RT)

Multiinstitutional Open Label Randomized Phase II Study Comparing Cetuximab and Radiotherapy Versus Cisplatin and Radiotherapy as Firstline Treatment for Patients With Locally Advanced Squamous Cell Carcinoma of the Head and Neck (LA-NHSCC)

BACKGROUND:

Concomitant radiotherapy and cisplatin (CDDP) based chemotherapy is the standard treatment for LA-NHSCC. This combined modality treatment is linked with considerable acute local and systemic toxicity.EGFR is overexpressed in 90-100% of the HNSCC cases and is considered an unfavourable prognostic marker. EGFR costitutive activation is linked with HNSCC pathogenesis.

Cetuximab is a monoclonal anti-EGFR antibody blocking the activation of the receptor and signal transduction. Cetuximab combined with radiotherapy is superior to radiotherapy only in the treatment of LA-HNSCC and is characterized by an acceptable toxicity profile.

RATIONALE:

A direct comparison between concomitant chemoradiotherapy with Cisplatin and the concomitant treatment with radiotherapy associated to cetuximab does not exist.

STUDY DESIGN:

Arm A: Radical radiotherapy (doses and volumes) concomitant with chemotherapy with Cisplatin (40 mg/mq/week) Arm B: Radical radiotherapy (doses and volumes) concomitant with therapy with the monoclonal antibody Cetuximab (400 mg/m2 ["loading dose"] and subsequently 250 mg /m2/week)

Study Overview

• Status: Terminated
• Conditions: Head and Neck Neoplasms; Pharyngeal Neoplasms; Mouth Neoplasms; Laryngeal Neoplasms
• Intervention / Treatment: Drug: cetuximab; Drug: cisplatin (associated to radiotherapy)

Detailed Description

PRIMARY OBJECTIVES:

Evaluation and comparison of the compliance of the two treatments;

SECONDARY OBJECTIVES:

Evaluation and comparison of the grade and incidence of acute toxicity; Evaluation and comparison of local control; Evaluation and comparison of event free survival (both local control and distant metastases); Evaluation and comparison of cause specific and overall survival.
