### The Placebo Effect in Veterinary Medicine: Interpreting Clinical Study Results in Placebo-Controlled Studies
Here’s a number that should make every clinical development team uncomfortable: in placebo-controlled veterinary studies, 40–74% of pet owners report their animal improved — on a placebo.
Trained veterinarians? They’re not much better. 43–45% report improvement too.
On March 24, Tommy Jackson is sitting down with Dr. Marie-Paul Lachaud, who co-founded Europe’s first veterinary CRO and has spent 35 years designing effectiveness studies, to dig into what this means for our field.
**In this session, we’ll cover:**
- Why the caregiver placebo effect is structurally different from the human placebo effect
- Where it’s killing trials that should have succeeded (and masking drugs that should have failed)
- Study design strategies that separate real effects from perception
**Tuesday, March 24 | 10:00 AM Central Time | 30 minutes**
