Clinical Research

Time & Travel Compensation For Most Trials. Enroll Today!

Centennial Research Center has managed over 160 clinical trials since 2003 ranging from high enrolling vaccine studies, to new diagnostic device studies, to complex pharmaceutical trials that involve highly specialized patient bases. We have worked with most major pharmaceutical companies, many of whom come back again and again to our practice because of the quality of our data, availability of our Primary Investigators, ability to enroll different therapeutic areas, and the ease of doing business with us.

The overarching company, Centennial Medical Group, is a Primary Care medical practice working closely with our research division in patient recruitment and management. The practice has a database of over 100,000 patients who are widely diverse in both age and condition and who receive routine care in a variety of specialty areas. The sizable primary care practice allows our research providers to maintain a constant presence on the front lines of patient care.

Our operations and staff are qualified to handle a wide variety of Phase 1 through phase 4 studies, ranging from 1 to 700 study participants, and our research-patient population includes a cross section of ethnic backgrounds, ages, and medical conditions. The research department was awarded the Site Patient Recruitment innovation award (SPRIA) by the Society of Clinical Research Sites in 2021 for achieving high enrollment and high diversity of enrolled patients through innovative recruitment using mobile buses.

Centennial Research Center is committed to world-class research results and the development of quality assurance programs via rigorous staff education and internal audit programs. Continuous quality improvement, an ongoing effort, involves CRC’s entire staff, and weekly training meetings are mandatory, as the key to quality research is constant training. Constant communication between sponsors, CROs, monitors, and Centennial Research Center staff helps provide optimal results.

What Is A Clinical Trial?

Clinical trials are the method by which new medications and treatments are evaluated for safety and effectiveness. The Food and Drug Administration requires all new drugs and treatments to be thoroughly tested before they are approved for use, usually in 4 phases of trials.

Participants in clinical trials can gain access to new treatments before they become widely available for routine use, and contribute to the advancement of medical science. These advancements help improve our quality of life and provide cures for previously untreatable diseases.

Clinical research volunteers receive free medical evaluations during the research visits and are compensated for their time and travel expenses.
