Effectively, the data indicate that the COMT val158met allele could represent a marker for placebo responders in IBS patients at least, the investigators state. (genengnews.com)
And inclusion of the control waitlist patients, who were by far the least likely to "respond" and didn't show any link between response and COMT polymorphism, acted to support the notion that met is a true predictor of the placebo effect, and not just improvements in general. (genengnews.com)
In fact, they point out, although a number of studies have previously looked at the placebo response, it's the addition of a no-treatment control arm (the waitlist group in this case), and an 'augmented' therapy arm that has provided a clear demonstration that a genetic factor can play a role in whether patients will respond to placebo, albeit with subjective (in the case of IBS), but measurable improvements in symptoms.
