Attached is the prescribing information for Tykerb as approved by the FDA. Due to strict FDA regulations, GSK cannot comment or advise on any condition not addressed within this document.
But your oncologist is free to discuss with you any questions or applications of Tykerb not covered by this document. Feel free to talk to her/him.

This is one of the most important reasons to consider entering clinical trials of Tykerb or any other promising drug. The FDA will only act on proven studies submmited to them. Without solid information confirming the suitability of any application, the FDA will not approve any devience from the "boxed labeling"
