Multimodal Therapy With and Without Cetuximab in Patients With Locally Advanced Esophageal Carcinoma - An Open-Label Phase III Trial
OBJECTIVES:
Primary
- To determine the efficacy of neoadjuvant radiochemotherapy comprising docetaxel,
cisplatin, and radiotherapy in combination with cetuximab followed by surgery and
adjuvant cetuximab versus neoadjuvant radiochemotherapy comprising docetaxel,
cisplatin, and radiotherapy followed by surgery in patients with locally advanced
esophageal carcinoma.
Secondary
- To compare the toxicity of the two therapy arms.
- To determine patterns of failure overall and with regard to histology.
- To evaluate economic aspects in a subproject and to perform a radiotherapy quality
assurance program.
OUTLINE: This is a multicenter study. Patients are stratified according to center, histology
(adenocarcinoma vs squamous cell carcinoma), primary tumor (T2 vs T3-4), and gender (male vs
female). Patients are randomized to 1 of 2 treatment arms.
- Arm A:
- Induction chemotherapy (docetaxel and cisplatin) and concurrent cetuximab Patients
receive docetaxel IV over 1 hour and cisplatin IV over 1 hour on day 1 and
cetuximab IV over 1-2 hours on day 1, 8, and 15. Treatment repeats every 21 days
for 2 courses.
- Chemotherapy (docetaxel and cisplatin), cetuximab, and concurrent radiotherapy
Beginning in week 7, patients receive cetuximab IV over 1 hour, docetaxel IV over
30 minutes, cisplatin IV over 1 hour on days 43, 50, 57, 64, and 71 and undergo
radiotherapy 5 days a week for 5 weeks. Patients then undergo surgery 4-7 weeks
after completion of radiotherapy.
- Adjuvant cetuximab Beginning 3-6 weeks after completion of surgery, patients
receive cetuximab IV over 1-2 hours once every 2 weeks for a total of 6 doses.
- Arm B: Patients receive induction chemotherapy comprising docetaxel IV and cisplatin IV
for 2 courses as in arm A. Beginning in week 7, patients receive docetaxel IV,
cisplatin IV, and concurrent radiotherapy for 5 weeks as in arm A. Patients then
undergo surgery 4-7 weeks after completion of radiotherapy.
After completion of study therapy, patients are followed up at 1 (arm B) or 6 (arm A)
months, every 3 months for 3 years, and then every 6 months for 2 years.
