What is Telaprevir and why is this study important?

Telaprevir is an investigational drug developed by Vertex Pharmaceuticals. This study is important because it evaluates Telaprevir's effectiveness in patients who have previously not responded to standard Hepatitis C treatments (Peginterferon and Ribavirin). The preliminary results offer early insights into Telaprevir's potential as a new treatment option for this resistant patient group.

Where can I find the detailed preliminary results?

The filing itself contains an abstract (Exhibit 99.1) with the preliminary results. This abstract was posted online by the European Association for Study of the Liver (EASL) and will be presented at their 43rd Annual Meeting. Investors interested in the specifics should refer to this abstract and any subsequent presentations or publications from EASL.

What does 'preliminary results' mean for investors?

'Preliminary results' indicates that the study data is early and has not yet undergone full analysis or peer review. While encouraging, these findings are subject to change as the study progresses and more comprehensive data is gathered. Investors should view these results as an initial indicator of potential and not a final determination of efficacy or safety.

What is the significance of EASL for this announcement?

EASL (European Association for Study of the Liver) is a reputable medical association. Having preliminary results posted and presented through EASL lends credibility to Vertex's findings and suggests that the data is considered scientifically significant by the liver disease community.
