Clinical trials are a necessary component in developing new medicine. Research teams investigate new drugs to test their effectiveness. Trials on new drugs can only begin once they are deemed safe and effective for people to use.

There are eligibility requirements for those interested in participating in clinical studies. These requirements can vary, depending on the patient's medical condition, age or even gender. Once qualifying, a study coordinator will meet with participants and explain the study, including its risks and benefits.

Patients must be fully-informed and completely understand the schedule of treatment, any procedures, potential positive or negative effects, before they can participate in the study. A volunteer may decide at any time to withdraw from the study, completing exit interviews to confirm a safe exit from the study.

It is a weighted decision to participate in these studies. Our staff is prepared to give any assistance necessary for patients to make informed decisions regarding their health. By participating in a clinical trial, patients are contributing to the advancements of new therapeutic areas of medicine. Our staff remains dedicated to ensuring the best patient care in all of RCA's clinical research.

Are you a patient seeking new treatments for your condition? RCA seeks patients with a wide range of conditions.
