E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of this study is to improve PFS of patients with stage IV colorectal carcinoma, who progressed on (or are intolerant to) 5-FU, oxaliplatin, irinotecan, anti-VEGF (and/or anti-EGFR) containing therapy, treated with high-dose sunitinib (once every 2 weeks) to 5 months, compared to 2 months for patients treated with TAS-102 monotherapy. Progression free survival is defined as the time from randomization to the date of the first documented tumor progression as determined by the investigator using RECIST 1.1 criteria or death due to any cause. PFS between patients included in the two different study arms will be compared. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After 9-10 weeks of treatment by CT-scan (RECIST 1.1) and every 2 weeks by physical exam en laboratory exam. |
|
E.5.2 | Secondary end point(s) |
Secondary objectives are:
1: Overall Survival (OS), counting from the date of study inclusion (and randomization) to the date of death of the patient (from any cause) or to the last day of follow-up.
2: To determine quality of life (QoL) of patients in the study. The difference in quality of life between two treatment arms will be assessed. Patients will complete the European Organisation for Research and Treatment of Cancer Quality of Life questionnaires (EORTC QoL) to evaluate this objective. A total of 2 questionnaires will be included; EORTC QlQ-C30 Version 3.0 to assess QoL of cancer patients in general and EORTC-QLQ-CR29 to asses QoL of CRC cancer patients.
3: To determine safety and tolerability of the two drugs. In this study two therapeutic drugs are compared in an attempt to improve survival of patients with CRC. TAS-102 had been previously safely used in patients with mCRC. Sunitinib is already registered for various cancer types with acceptable toxicity, but not at this dosing regimen and for mCRC. Safety and tolerability will be studied by analysis of adverse events, physical examinations, vital signs, Eastern Cooperative Oncology Group (ECOG) performance status, and laboratory-abnormality assessments (complete blood count with differential count, serum electrolyte measurements, and electro cardiogram). Severity of adverse events will be rated by investigators by use of the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0.27. CTCAE (2006)
4. Liquid biopsies for circulating blood biomarker analysis including microRNA and platelets containing tumor-derived RNA. Evaluation of potentially predictive circulating biomarkers could help in identifying patients, rather easily by venepuncture, who will not benefit from treatment and thereby may provide a potential selection tool to avoid unnecessary treatment and its associated toxicity. The potential value of blood markers for molecular diagnostics, disease and response monitoring will be assessed.
5. A cost effectiveness (utility) analysis will be performed from a health care perspective, using a 3-year time horizon. The median overall survival in this patient population is 7 months, so all health effects and costs will be covered within a 3-year time horizon. The direct-medical and total costs will be included. Direct medical costs taken into account will include treatment costs, cost of hospitalization, medication, imaging, laboratory testing and pathology. Within the trial, resource use will be monitored and this will be linked to integral cost prices or Dutch tariffs, using the CVZ guideline on costing studies as our basis. Health-care costs incurred outside the hospital, such as the attendance of a general practitioner will be assessed using the Health Resource Usage Assessments questionnaire.
The primary health outcome measure in this economic evaluations will be the total quality adjusted life years (QALY) per trial arm. QALYS will be calculated by using the utility scores linked to the various health states of the EQ-5D (Appendix VIII); in essence the length of time a patient spends in a particular health condition is weighed by the corresponding utility. Missing data on costs and utilities will be imputed using multiple imputation. The difference in total costs and total QALYs in both arms will be used to calculate the incremental cost-effectiveness ratio (ICER): the cost per QALY gained (or cost-savings per QALY gained or lost), using the formula: ICUR = (Cintervention - Ccontrol) / (QALYintervention - QALYcontrol).
Using the non-parametric bootstrap, a probabilistic sensitivity analysis will be performed to examine the uncertainty around the base-case cost-effectiveness estimate. Furthermore, as the expiration date of the patent for sunitinib approaches, we foresee that the cost for this treatment will decrease significantly.
6. Phosphoproteomics profiling on tumor biopsy. Development of agents blocking kinases has established the use of molecularly targeted therapy for patients with metastatic cancer. It is unclear which patient will respond to targeted therapy. It is assumed that responses to targeted agents depend on specific receptor and protein signalling activities in tumor tissue. Therefore, protein phosphorylation profiling with phosphoproteomics will be explored as a potential clinical diagnostic tool to predict for tumor response to targeted therapy in a subgroup of the patients that are willing to undergo a tumor biopsy from a metastasis (not mandatory for participation). |

E.5.2.1 | Timepoint(s) of evaluation of this end point |
1: Until death survival follow-up will take place every 12 weeks.
2: After study inclusion, and every 9 weeks (with a possibility to extend with 1 week) until progression of disease, patients will be asked to complete The European Organisation for Research and treatment of Cancer Quality of Life questionnaires (EORTC QoL).
3: Every hospital visit using CTCAE version 4.0
4: By Screening and every 2 weeks (hospital visit) after 8 weeks this wil be extended to every 4 weeks.
