About us
Leading the way in physician-led clinical trials
Yanuvia is the unique integrated research organization created out of one physician’s desire to elevate clinical trial procedures. The result: We provide significant advantages for both medical practices and trial sponsors — faster start up, streamlined processes, and the highest quality every step of the way.
For years, clinical research trials were all conducted in much the same way: a time-consuming, challenging procedure that made sponsors anxious, burdened patients, and held little attraction for physician involvement.
But at Yanuvia, we’ve changed all that — for the better. Our unique focus on community physician-led clinical trials has transformed the landscape. Sponsors can focus on analyzing the data and bringing their products to market sooner, while physicians can further advance patient care while realizing ancillary revenue.
We invite you to experience a more cost-effective, more productive and less stressful clinical trial experience.
