R eal-world data from the largest U.S. Lyme disease registry, MyLymeData, shows current clinical trials for persistent Lyme disease (PLD) systematically exclude most patients who are clinically diagnosed with the condition.
A groundbreaking analysis of over 4,000 patients reveals that 9 out of 10 people with PLD are barred from participating in clinical trials, primarily due to outdated eligibility criteria.
The impact is severe. Nearly two million Americans live with PLD, with 72% reporting poor or fair health—compared to just 13% of the general population. These patients also face elevated suicide risk.
“The way researchers currently design clinical trials excludes 90% of patients, resulting in small studies that take too long, cost too much, and don’t apply to most patients,” states Lorraine Johnson, CEO of LymeDisease.org and principal investigator of MyLymeData. “Overly stringent criteria exclude the very patients we need to study, leaving clinicians without relevant findings for their practice.”
