The Placebo Problem, Part 9: Training Achieves Smaller Placebo Responses

This is the ninth installment of our look at the increasingly high placebo response that is plaguing clinical trials in analgesia and psychiatry. View the other posts in the series here. Our last post reviewed several potential strategies to reduce the placebo effect, focusing on excluding high placebo responders and alternative trial designs. Today, we’ll...

The Placebo Problem, Part 7: Drug-Placebo Interactions

Our seventh installment of The Placebo Problem continues our look at the increasingly high placebo response that is plaguing clinical trials in analgesia and psychiatry. Check out the other posts here. The placebo response is broad. It goes far beyond the effects of merely consuming a sugar pill; it is the patient’s response to the...

The Placebo Problem, Part 6: Measuring the Placebo Response

This is the next installment of our look at the increasingly high placebo response that is plaguing clinical trials in analgesia and psychiatry. Check out the other posts here. Over the past few weeks, we’ve discussed the psychological, neurobiological, and genetic mechanisms responsible for the placebo response. Today, we turn to the study designs used...

The Placebo Problem, Part 5: The Placebome

This is the fifth installment of our look at placebo response issues in analgesia and psychiatry clinical trials. Read other posts in the series here. Studies examining genetic variants associated with high or low placebo responses – the “placebome” – are relatively recent, but represent an important line of research that can yield insights into...

The Placebo Problem, Part 4: Neurobiological Mechanisms

This is the fourth in our series examining the increasingly high placebo response issues plaguing analgesia and psychiatry clinical trials. Additional posts in the series are located here. As with many other aspects of placebo research, the majority of research on underlying neurobiological mechanisms has focused on placebo analgesia. In fact, roughly 40 positron emission...

The Placebo Problem, Part 1: Overview

For hundreds of years, the medical community has known that the mere act of receiving treatment, even if it’s just a sugar pill, can improve a patient’s symptoms. Therefore, in order to ensure that the effects of an experimental treatment are real, most randomized controlled trials (RCTs) include a placebo arm. Placebos are most often...

Fighting the Placebo Effect in Fibromyalgia Drug Trials

Placebo response is an ever-present threat in analgesia clinical trials, and failure to sufficiently prove the efficacy of the researched compound can easily doom your promising new product. The risk can be especially pronounced when studying drugs to treat fibromyalgia. Fibromyalgia patients can be — and don’t use the term casually or critically — needy....
