Trial Outcomes & Findings for Definitive Radiochemotherapy Plus/Minus Cetuximab in Unresectable Locally Advanced Esophageal Cancer (NCT NCT01787006)

NCT ID: NCT01787006

Last Updated: 2020-03-10

Results Overview

Overall Survival (OS) was defined as freedom from death of any cause. Time to death was calculated from the day of randomization, and the patients were followed for a maximum of 24 months (2 years).

Cetuximab, Cisplatin, 5-FU, Radiotherapy
Cetuximab: Initial doses 400mg/m2 (day 1), followed by weekly doses of 250mg/m2 for 14 weeks in total, IV 5-FU: 1000mg/m2 per day as continuous infusion on day 8-11 and 36-39, 750mg/m2/day as continuous infusion on day 71-74 and 99-102 Cisplatin 20mg/m2/day as intravenous bolus over 60 min on day 1-4 of every cycle (day 8-11, 36-39, 71-74 and 99-102) radiotherapy: 59.4 Gy (33 fractions of 1.8 Gy) over 6.5-7 weeks (5 x 1.8 Gy per week)on primary tumor. 50.4 Gy on locoregional lymphnodes. If resectability is reached after 4-4.5 weeks (36-41.4 Gy) the radiotherapy stops after 45 Gy and the patient undergoes surgery.
Cisplatin, 5-FU, Radiotherapy
5-FU: 1000mg/m2 per day as continuous infusion on day 1-4 and 29-32, 750mg/m2/day as continuous infusion on day 64-67 and 92-95 Cisplatin 20mg/m2/day as intravenous bolus over 60 min on day 1-4 of every cycle (day 1-4, 29-32, 64-67 and 92-95) radiotherapy: 59.4 Gy (33 fractions of 1.8 Gy) over 6.5-7 weeks (5 x 1.8 Gy per week)on primary tumor. 50.4 Gy on locoregional lymphnodes.

Timeframe: up to 2 years

Response was defined according to the RECIST criteria (Version 1.1) based on the assessments (computed tomography, magnetic resonance imaging or other) for target lesions, non-target lesions as well as considering the occurrence of new lesions. The best overall response (RECIST) was chosen for each patient out of all valid tumour assessments before start of next-line therapy (complete response=CR being the best and progressive disease=PD the worst). Frequencies with percentages were to be given for each category (CR, partial response (PR), stable disease (SD), PD) by treatment group. The data were to be presented as the dichotomous endpoint of objective response, for which patients with best overall response of CR or PR were considered as responders, and those with best overall response of SD or PD as non-responders. The difference between objective response rates in the two treatment arms was to be compared with a Chi-square test.

Cetuximab, Cisplatin, 5-FU, Radiotherapy
n=32 Participants
Cetuximab: Initial doses 400mg/m2 (day 1), followed by weekly doses of 250mg/m2 for 14 weeks in total, IV 5-FU: 1000mg/m2 per day as continuous infusion on day 8-11 and 36-39, 750mg/m2/day as continuous infusion on day 71-74 and 99-102 Cisplatin 20mg/m2/day as intravenous bolus over 60 min on day 1-4 of every cycle (day 8-11, 36-39, 71-74 and 99-102) radiotherapy: 59.4 Gy (33 fractions of 1.8 Gy) over 6.5-7 weeks (5 x 1.8 Gy per week)on primary tumor. 50.4 Gy on locoregional lymphnodes. If resectability is reached after 4-4.5 weeks (36-41.4 Gy) the radiotherapy stops after 45 Gy and the patient undergoes surgery.

n=36 Participants
5-FU: 1000mg/m2 per day as continuous infusion on day 1-4 and 29-32, 750mg/m2/day as continuous infusion on day 64-67 and 92-95 Cisplatin 20mg/m2/day as intravenous bolus over 60 min on day 1-4 of every cycle (day 1-4, 29-32, 64-67 and 92-95) radiotherapy: 59.4 Gy (33 fractions of 1.8 Gy) over 6.5-7 weeks (5 x 1.8 Gy per week)on primary tumor. 50.4 Gy on locoregional lymphnodes. If resectability is reached after 4-4.5 weeks (36-41.4 Gy) the radiotherapy stops after 45 Gy and the patient undergoes surgery.

SECONDARY outcome

Timeframe: end of treatment (after 5 to 13 weeks)

Population: All scales used for the rows below in the outcome measure data table ranged between 0 and 100. For scales indicated \[H\], a higher score represents a better situation (quality of life, functioning). For scales indicated \[L\], a lower value represents a better outcome (symptoms/problems).

Quality of Life was assessed with EORTC QLQ-C30 and QLQ-OES18 questionnaires. For QLQ-C30, global health status, functional scales (physical, role, emotional, cognitive and social functioning) and symptom scales (fatigue, nausea/vomiting, pain, dyspnea, loss of appetite, constipation, diarrhea, financial difficulties) were calculated. Scores ranged from 0 to 100; higher scores represented higher levels of quality of life, functioning, or symptoms/problems. Score were calculated using mean values. For QLQ-OES18, symptom scales (problems with eating, reflux, pain, problems swallowing saliva, dry mouth, taste disorders, problems while coughing or speaking) and functional scale (dysphagia) were assessed the same way. A change between two time points, i.e. baseline (prior to treatment) and end of treatment (after 5 to 13 weeks, depending on treatment arm (6.5 weeks without and 13 weeks with cetuximab) and achievement of resectability (end of treatment after 5 weeks), is reported.

Cetuximab, Cisplatin, 5-FU, Radiotherapy
n=32 participants at risk
Cetuximab: Initial doses 400mg/m2 (day 1), followed by weekly doses of 250mg/m2 for 14 weeks in total, IV 5-FU: 1000mg/m2 per day as continuous infusion on day 8-11 and 36-39, 750mg/m2/day as continuous infusion on day 71-74 and 99-102 Cisplatin 20mg/m2/day as intravenous bolus over 60 min on day 1-4 of every cycle (day 8-11, 36-39, 71-74 and 99-102) radiotherapy: 59.4 Gy (33 fractions of 1.8 Gy) over 6.5-7 weeks (5 x 1.8 Gy per week)on primary tumor. 50.4 Gy on locoregional lymphnodes.
