I think the reason is simply there is not a "placebo" group. As these are very ill patients (in an advance phase of the disease) the control group is usually the standard treatment they are receiving, to which the new treatment is added in the test groupUsually this is the case in cancer research but I will try to find the study and let you know what I find outRegards
