Research Trials

Our clinic has partnered with some of the world’s largest pharmaceutical companies like Pfizer, Astra-Zeneca and Novartis and we are excited to offer residents of Oklahoma the opportunity to participate in cutting-edge research trials.

Patients who choose to enroll in a Research Trial further the advancement and development of new therapies, while obtaining considerable personal benefit and improvement in health.

Eligible patients receive trial-related care at no charge:

Physicals
EKG
Lab Work
Medications
Financial Compensation

All enrolment is 100% voluntary and open to all Oklahomans. Eligible patients are supervised by our physician Angelique Barreto MD, MSc for trial-related care. Patients continue to see their own PCP and Specialists as usual, and regular trial-related updates can be sent to their personal providers at patient request. Dr. Barreto has 19 years of experience in Clinical Research, and has supervised over 80 trials. More than 1,000 Oklahomans have safely participated in trials under her care, and contributed to the development of many life-saving medications now in use through-out the world.

For more information on our ongoing trials please call (405) 286-1075 or Click here.

I will partner with you to develop a tailored, comprehensive wellness plan that delivers in-depth knowledge and one-on-one support all year long.

Getting old is not for old people. But Dr Barreto makes it a lot easier to take. Feeling and being healtier is more important now than any other time in my life and I feel I am in great hands with her keeping me going.

Sue H.

Dr. Barreto explained my lab results to me very thoroughly and when I told her I didn’t want to be dependent on medications for the rest of my life she came up with a plan of supplements to address my pre-diabetes. I am so happy she considered alternatives to meet my needs and the needs of my body. – Sue H.

Debbie D.

I had unexplained weight gain over the past year that was becoming depressing. No one would take the time to find out why it was happening. Dr. Barreto really looked into my concerns and lab results to find out what was going on. Now I am on a plan that includes supplements and exercise and I can see the results I have been looking for. – Debbie D.

Never had so much information given to me. The exam part was easier and less time consuming than expected. The Exam was also pleasant she was very professional and explained everything as it was happening. My visit for the outcome with Dr Barreto was also professional and really informative. I felt that I knew my overall health, risks and what to do.

Wellness Exam

This is my second “Wellness Exam” through MDVIP. Dr. Barreto and her staff provide a thorough process in a very professional and courteous manner. I appreciate the comprehensiveness and how the results are reviewed. Dr. Barreto provides a means of improving any less than good issues and she and her staff follow-up to see that they are effective. I am very pleased with the process. Thank You,
Cindy E.
