Double dummy is a technique for retaining the blinding of a clinical trial, when the two treatments cannot be made identical.
Supplies are prepared for Treatment A–active and indistinguishable placebo, and for Treatment B–active and indistinguishable placebo. Subjects then take two sets of treatment; either A–active and B–placebo, or A–placebo and B–active.
