Design outcomes

Primary

MeasureTime frame
Dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) at the end of cycle measured by adverse events monitoring

Secondary

MeasureTime frame
1. Safety profile at each visit measured by adverse events monitoring 2. Tumour response evaluation at baseline and at the final visit measured by imaging and blood tests 3. Tumour perfusion measurements only for schedule 1 using functional imaging 4. Exploration of changes in biological markers (optional part in schedule 1) using biopsies
