Testimonials
I was very fortunate to participate in a clinical research study, not only because I have benefited from a new cholesterol-reducing drug, but also because of the relationship with the doctor’s office that developed out of the trial led to the early detection and treatment of a heart condition that might otherwise have been fatal in a few years.
I have participated in many asthma clinical research studies. You really feel like they [study staff] care about your health and they are there to provide support and suggestions regarding your health such as new drugs that may help you down the road. That is why I participate in these studies because I am always looking to improve my health.
The clinical trial I participated in was a very rewarding experience. The drug I was trailing was a positive for my condition. My provider of the study was very knowledgeable and extremely helpful. My appointments were always on time and conducted with the utmost care. A job well done.
