Glucocorticoids can severely impact growth and development in children, lead to adverse events in puberty, and can affect overall wellness throughout adulthood. To fully address these impairments, the pGTI:

The pGTI provides the only clinical outcome assessment (COA) that drug developers can rely on to demonstrate improved safety of their new treatment compared to steroids alone. When a new therapy is shown to be non-inferior to standard therapy with regard to efficacy, the safety of the new agent, as measured by the pGTI, becomes of paramount importance.
The Steritas pGTI is comprised of two components: the Core Index and the Damage Checklist. The Core Index is built on nine domains that are standardized and weighted to quantify and compare indicators of toxicity that may occur over the course of a clinical trial. The Damage Checklist is an inventory of steroid toxicities that are less common yet are often severe and generally reflect permanent damage from prior steroid use. The pGTI merges these two components in an intuitive workflow that aligns with the normal course of data collection in a clinic visit.
The Steritas pGTI provides a nuanced view of patient results, which are summarized in the SteriTox Profile for each patient. The Cumulative Worsening Score (CWS), and the Aggregate Improvement Score (AIS), summarize all of the data entered into the pGTI. Higher scores indicate higher toxicity (worsening); lower scores indicate lower toxicity (improvement). Therefore, if an investigational treatment is effective in decreasing steroid-toxicity over time, the CWS and AIS will be lower in the investigational arm of the trial.
The pGTI balances rigorous data analytics with an intuitive data entry process that simplifies use for everyone that collects patient data during the course of a clinical trial.
Each patient visit can be recorded in just a few minutes. Data entry can be entered all at once or as patient data become available. Your patient’s SteriTox Profile is reported as soon as all required modules are complete.

“What you gain by adding the Steritas GTI to a clinical trial is a systematic way of assessing steroid-toxicity.”
We welcome your interest in the Steritas GTI and pGTI. All uses of these instruments require a license, whether you are an academic researcher, biotech start-up, a large pharmaceutical company, or a clinical research organization.
Steritas will structure a use license to support the scope and design of your trial and the needs of your organization.
The Steritas GTI provides a definitive outcome measure for clinical investigators to compare efficacy and safety of new drug protocols to conventional steroid therapies. In recent clinical trials that resulted in FDA approval of avacopan as an add-on treatment to standard therapy including glucocorticoids for adult patients with severe active anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, glucocorticoid-induced toxic effects were secondary endpoints of the trial, as measured by both the GTI-CWS and GTI-AIS. Additional clinical trials are underway that are using the Steritas GTI to support primary and secondary safety endpoints.
