Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Clinical Benefit Rate
Tidsramme: At the completion of 6 cycles of chemotherapy, which is after 18 weeks
|
Defined as stable disease rate + partial response rate+complete response rate according to RECIST 1.1 criteria
|
At the completion of 6 cycles of chemotherapy, which is after 18 weeks
|
|
Objective Response Rate
Tidsramme: At completion of 6 cycles of chemotherapy, which is after 18 weeks.
|
Objective response rate (ORR) is defined as complete response (CR) plus partial response (PR) as per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by CT scan every 6 weeks. Tumours were assessed at baseline and compared to the response seen at the completion of treatment. Only responses seen within the 6 cycles of treatment e.g. up to and including the end of treatment tumour assessment are included in this measure. CR - Disappearance of all target lesions; PR >=30% decrease in the sum of the longest diameter of target lesions. |
At completion of 6 cycles of chemotherapy, which is after 18 weeks.
|
|
Overall Survival
Tidsramme: Determined as the time from randomisation to death from any cause. Average survival rates for this population may be approximately 18 months.
|
Survival duration from randomisation to date of death.
|
Determined as the time from randomisation to death from any cause. Average survival rates for this population may be approximately 18 months.
|
|
Time to Next Chemotherapy Treatment
Tidsramme: Measured from from the date of the last day of trial treatment. approximately after progression which on average would be after 12 months.
|
time from randomisation to another chemotherapy treatment after confirmed progression.
|
Measured from from the date of the last day of trial treatment. approximately after progression which on average would be after 12 months.
|
|
Time to Response
Tidsramme: Determined by time from randomisation to radiological partial response. This was sometimes seen after treatment end but all responses occurred by 8 months from randomisation therefore within 32 weeks.
|
Time taken for tumour burden to respond to treatment
|
Determined by time from randomisation to radiological partial response. This was sometimes seen after treatment end but all responses occurred by 8 months from randomisation therefore within 32 weeks.

Assessment of EQ-5D-5L Questionnaire
Tidsramme: EQ5D-5L and FACT B will be completed at baseline, prior to cycle 3 (approximately Day 63), prior to cycle 5 (approximately Day 105) and at the end of treatment visit, (approximately 21 weeks)
|
EQ-5D-5L will be assessed at baseline, prior to cycle 3 and cycle 5 and at the end of treatment.
The patients answer 5 questions which have 5 possible answers from no issue to extreme issue.
The answers are given a code, 1, 2, 3, 4 or 5 with 1 for no issue through to 5 for extreme issues which results in a 5 digit 'health state' for that time point.
Using a formula this is translated into the 'EQ-5D index value' where 1 is full health and 0 is the worst health.
This is what is presented here, the lower the score the worse the quality of life.

EQ5D-5L and FACT B will be completed at baseline, prior to cycle 3 (approximately Day 63), prior to cycle 5 (approximately Day 105) and at the end of treatment visit, (approximately 21 weeks)

Assessment of EQ-5D-5L VAS Score
Tidsramme: EQ5D-5L and FACT B will be completed at baseline, prior to cycle 3 (approximately Day 63), prior to cycle 5 (approximately Day 105) and at the end of treatment visit, (approximately 21 weeks)
|
EQ-5D-5L VAS score was assessed at baseline, prior to cycle 3 and 5 and at the end of treatment.
Patients are asked to score their health on a scale 0-100, the higher the score the better they are feeling.
|
EQ5D-5L and FACT B will be completed at baseline, prior to cycle 3 (approximately Day 63), prior to cycle 5 (approximately Day 105) and at the end of treatment visit, (approximately 21 weeks)

Assessment of FACT-B Questionnaire
Tidsramme: EQ5D-5L and FACT B will be completed at baseline, prior to cycle 3 (approximately Day 63), prior to cycle 5 (approximately Day 105) and at the end of treatment visit, (approximately 21 weeks)
|
FACT-B will be assessed at baseline, prior to cycle 3 and cycle 5 and at the end of treatment.
The patients answer 37 questions which have 5 possible answers from not at all to very much.
The answers are given a code, 0, 1, 2, 3 or 4 with 0 for not at all through to 4 for very much.
The scores are reversed and then totalled to give a value out of 148.
This is what is presented here, the higher the score the better the quality of life.
