| E.5 End points |
| E.5.1 | Primary end point(s) |
Primary Outcome Measures:
1. Definitive (efficacy) endpoint: overall survival time
2. Interim outcome measure (activity stages): event free survival time
|
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
For the arm 3 and 4 comparisons, once 71 control EFS events (for the ‘eligible comparison’) have been recorded then this will trigger the analysis for stage I; 116 control EFS events are required for stage II. It is now anticipated that the primary outcome measure for the original experimental arms (3 and 4) will be reached after 8.5 years
Arm 5;
The interim assessments for arm 5 will be carried out when 45 (1st stage) and 75 (2nd stage) contemporaneous control (arm 1) EFS events have been observed.
The total recruitment for the arm 5 comparison is forecast to be 4.5 years |
|
| E.5.2 | Secondary end point(s) |
Secondary Outcome Measures:
1. Total number of acute (<3 months post-treatment) and late (up to 2 years) severe (grade 3-5) toxicity events at 2 years post randomisation, measured by Common Terminology Criteria for Adverse Events version 4.0
2. Overall and head and neck specific Quality of Life at 24 months post randomisation, using the European Organisation for Research and Treatment of Cancer (EORTC) C30 and HN35 Questionnaires
3. Swallowing outcomes using M.D. Anderson Dysphagia Inventory (MDADI) Questionnaire at 24 months and percutaneous endoscopic gastrostomy utilisation rates at 1 year
4. Cost effectiveness using EuroQol Group (EQ-5D), patient diaries and primary and secondary resource utilisation data
5. Surgical complication rates |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
1. Measured weekly during treatment and then monthly during year 1 of follow-up and 2 mothly during year 2 of follow-up
2. Measured at baseline (trial entry) and at months 3, 6, 12, 18 and 24 of follow-up.
3. Measured at baseline (trial entry) and at months 3, 6, 12, 18 and 24 of follow-up.
4. Measured at baseline (trial entry) and at months 3, 6, 12, 18 and 24 of follow-up.
5. Following surgical resection
The secondary outcome measure of event free survival will be evaluated on 3 occasions as an interim analysis after 70, 114, & 169 event free survival events have been observed. These are projected to be at approximately 3, 4 and 5 years after recruitment has commenced. |
