Experimental: Treatment-Arm |
Drug: Cabozantinib
Cabozantinib is administered orally at the dose of 60 mg per day.. |
- Evaluate the efficacy of Cabozantinib treatment via DCR after 6 months. [ Time Frame: 6 months ]Disease control rate (DCR) 6 months after treatment start .
- Evaluate short- and long term efficacy of Cabozantinib treatment via DCR. [ Time Frame: 12 months ]DCR 3 and 12 months after treatment start.
- Evaluate short- and long term efficacy of Cabozantinib treatment via ORR. [ Time Frame: 12 months ]Objective response rate (ORR) 3, 6 and 12 months after treatment start and best objective response rate.
- Evaluate short- and long term efficacy of Cabozantinib treatment via PFS. [ Time Frame: 24 months ]Progression free survival (PFS).
- Evaluate short- and long term efficacy of Cabozantinib treatment via OS. [ Time Frame: 24 months ]Overall survival (OS).
- Evaluate exposure time. [ Time Frame: 12 months ]Time on drug (TOD).
- Assess quality-of-life during and after Cabozantinib treatment. [ Time Frame: 15 months ]EORTC QLQ-C30 Quality of Life Questionnaire monthly for 12 months after treatment start and after 15 months. Different questions regarding Quality of Life on a scale of 1 - 4. The lower the numbers, the better the quality of Life.
- Safety of Cabozantinib via AE and SAE assessment. [ Time Frame: 24 months ]Adverse events and serious adverse events will be assessed in contingency tables.
