Our commitment

Clinical trial information needs to reach the widest possible audience, including people who use assistive technology. We aim to conform to Web Content Accessibility Guidelines (WCAG) 2.2 Level AA across the public study site.

Accessibility is an ongoing effort. We review changes before release and accept feedback at any time.

What we do

Semantic HTML for structure and landmarks; visible focus rings on all interactive elements; keyboard support for every user flow; text content that reads correctly with screen readers; color contrast tested against WCAG AA thresholds; reduced-motion support for animations.

Known gaps

The interactive map on the Find a Site page can be challenging with some screen readers. A text-only site list is provided alongside the map, and all site details are reachable without using the map itself.

PDFs linked from the Resource Center are provided as a convenience; the primary content on each page is available in HTML for the best screen-reader experience.

Feedback
