Population: The analysis of toxicity was made in all study patients who had received at least 1 treatment cycle, or who had completed the observation period equivalent to 1 cycle.

Safety will be assessed by standard clinical and laboratory tests (haematology, serum chemistry). AE grade were defined by the NCI CTCAE (National Cancer Institute Common Terminology Criteria for Adverse Events).
