Who we are

A research site built on decades of clinical care.

The mission of EndoTrials Clinical Research Center is to help discover, apply, and translate science about endocrine disease, diabetes, and their complications, to improve health and wellness. EndoTrials continues the clinical research legacy of Diabetes and Endocrine Associates, a hallmark practice that has operated in the same San Diego–area locations since 1991.

We build on decades of know-how in clinical care and research, but what sets us apart is the operational nimbleness that modern trials demand. We are problem-solvers and creative thinkers committed to the highest quality standards. Work practice guidelines and standard operating procedures were developed specifically for EndoTrials, alongside site-specific forms used throughout every study. All documentation — including GCP training and IATA, EDP, and IMP certifications — is available for review upon request.
