We are here to
improve the way
steroids are used.

Track to taper

At Steritas, we address the challenges of measuring and minimizing steroid-toxicity to improve the standard of care for millions of patients around the world. We developed the Steritas GTI (Glucocorticoid Toxicity Index) to enable clinicians to track the direct impact of steroid-toxicity.


Today, the GTI provides a precise measure of the efficacy and safety of new therapies that treat inflammatory diseases and minimize the side-effects associated with glucocorticoid use.

We provide clinicians and patients with the tools to track steroid-toxicity so they can taper steroid usage and optimize treatment outcomes. 

Our Vision

A world free of steroid dependency

Our Mission

Measure and monitor steroid-toxicity, optimize treatment of inflammatory diseases, and improve the quality of patient care around the world


It’s time steroid-toxicity was measured and monitored.

We are clinical investigators
improving clinical investigation.

We solve the challenge of measuring and minimizing steroid-toxicity. The Steritas GTI was developed by an international group of 20 subspecialty experts and clinical investigators in:  rheumatology,pulmonary medicine, nephrology, neurology, psychiatry, dermatology, ophthalmology, pharmacology, maternal-fetal medicine, and infectious disease. The instrument was developed using data-driven analysis, expert consensus, and multi-criteria decision informatics.
