Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: • To study the efficacy of everolimus combined with temozolomide as first-line treatment in advanced gastrointestinal neuroendocrine carcinoma with a Ki67 of 20-55%, measured as disease control rate (non-progressive disease) at 6 months.; Secondary Objective: To assess: • Overall survival • Progression free survival • Objective response rate • Response duration • Safety profile • Quality of life using EORTC QLQ-C30 ;Primary end point(s): Disease control rate (CR+PR+SD) at six months according to RECIST-criteria (version 1.1). ; Timepoint(s) of evaluation of this end point: Baseline CT scans must be taken within 15 days prior to start of treatment. First CT evaluation must be performed after 6 weeks on treatment. Thereafter patients should be evaluated every 8th (+/- 2) week. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Objective response rates (CR+PR) according to RECIST v 1.1 Duration of response defined as time from objective response to progression of disease. Progression-free survival defined as time from study inclusion until progression of disease or death from any cause. Overall survival defined as time from study inclusion until death from any cause. Toxicity according to NCI CTCAE-criteria (v 4.0). Quality of life as measured with EORTC QLQ-C30. ; Timepoint(s) of evaluation of this end point: First CT evaluation must be performed after 6 weeks on treatment. Thereafter patients should be evaluated every 8th (+/- 2) week. Adverse events and symptoms: Every 4th (+/- 1) week from start of treatment. | — |
