Well clearly that's not true because placebo controlled trials into FMT for c.diff have been done in the USA. AIDS and cancer have objective measures, whereas with c.diff the trials just look at subjective measures.
Also, given that the placebo improvement rates are 40-90% in all c.diff trials, it would be unethical to not use a placebo arm.
