 Participants will be offered information about this study by their clinical teams if they are considered to meet the entry criteria and express interest in taking part in an experimental study. It will be made clear that the study is experimental in nature and that there will not necessarily be a therapeutic benefit from taking part in the study. It will also be made clear that, should patients decide not to take part their future care will not be affected. Patients will be given sufficient time and information to make an informed decision about entering the trial, and not less than 24 hours; all patients entering the trial will give written informed consent. Inclusion and exclusion criteria for this study are standard for a phase 1 trial of a new oncology drug.
