Clinical Trials

Focused on high-quality research

Texas Diabetes & Endocrinology (TDE) is dedicated to advanced research in Endocrinology.  Our three research sites are integrated within all of our office locations (Central Austin, South Austin and Round Rock).  Our board-certified physicians and experienced industry professionals are focused on high quality research in many areas of  Internal Medicine, but specialize in Diabetes, Thyroid, Osteoporosis, PCOS, Cholesterol, and Obesity/Weight loss.  Our goal is to improve the lives of our patients.  Through our practice- integrated research program, we have been able to increase the amount of Diabetes, Obesity, Thyroid, and Lipid research done in central Texas.  Our patients consistently tell us that they want new and better treatments for their endocrine conditions.  With over 10 years of clinical and device research experience, we are fortunate to have participated in studies involving new oral agents and injectables for the treatment of Diabetes,  CGM and pump devices, and multiple other oral and injectable medications for various indications, including lower cost generic medications. 

We excel at conducting Phase II-IV clinical, observational and device trials by recruiting directly from our large patient database, working with skilled coordinators and creating a team of enthusiastic Investigators.  Our extensive research sites have the capability to perform many protocol-specific procedures, such as nutritional counseling, HbA1c testing, Lipid testing, and Thyroid ultrasounds.
