What will I be asked to do?

You will be offered a screening visit and be provided with an information sheet describing the study in detail. If you are willing to enter the study, you will have some tests to confirm if you are able to take part. If eligible, you will attend a randomisation visit at which you will have further tests including a mixed meal tolerance test (MMTT) and your first treatment of Siplizumab or placebo. This will be followed by 13 further treatment visits of approximately 1 hour. After treatment, you will attend 3 further visits at weeks 24, 36 and 52, each lasting between 3 and 5 hours.
