Investigator Global Assessment Scale

Validated Investigator Global Assessment for Atopic Dermatitis (VIGA-AD™) Scale

Eli Lilly and Company (Lilly) worked with numerous atopic dermatitis experts, including International Eczema Council advisors and Industry experts, to develop the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD™) scale for use in clinical trials.

The vIGA-AD™ scale and the investigator training modules are available to companies and academic groups and offer licensed training and certification. The vIGA-AD™ scale, available in several languages, can be downloaded below. The training and certification exam are available through WCG's™ InvestigatorSpace® platform. To get started, visit WCG InvestigatorSpace™ to complete the form to receive EASI, BSA & TLSS certified training. Licensing for the vIGA-AD™ Scale beyond the provided training and certification is not available.

Once the inquiry form is submitted, you will be granted access to the requested training within 48 weekday business hours. Additional login information will be sent separately to the email provided. 

To ensure harmonization in the assessment of atopic dermatitis patients, we recommend that additional modifications are not made to the vIGA-AD™ scale. To use the scale in clinical trials or for other research purposes, use appropriate citations. If new translations are developed, we ask that copies of the translations and their certification of linguistic validation are provided to IEC to be made available to all and ensure consistency in the use of the scale across geographies.

Early development drafts of the vIGA-AD™ scale and its final version were previously shared with the US Food and Drug Administration (FDA) for input, and that feedback was incorporated into the final morphological descriptors. The FDA indicated that the final vIGA-AD™ scale was adequate to assess the efficacy of one of Lilly’s products under development for the treatment of atopic dermatitis at that time. 

The IEC thanks the Academic and Industry experts who participated in the development and validation of the vIGA-AD™ scale.
