Public Communication - Health Canada Endorsed Important Safety Information on APTIVUS® (tipranavir)

July 6, 2006

Subject: New Safety Information Regarding Risk of Intracranial Hemorrhage in HIV Patients using Aptivus® (tipranavir)

Boehringer Ingelheim, in collaboration with Health Canada, is informing you of new safety information regarding APTIVUS (tipranavir), a medication used in adult HIV patients who have not responded to other medications.

Boehringer Ingelheim has identified 14 cases of intracranial hemorrhage (ICH) (bleeding into the brain), including 8 deaths, in 6,840 HIV-1 infected patients receiving APTIVUS in clinical trials.

In more than half of the 14 cases, patients experiencing ICH also had other medical conditions or were taking other medications, including anti-coagulants (blood thinners) and anti-platelet (anti-clotting) agents, which may have contributed to these events.

No pattern of abnormal blood clotting was seen in these patients, however in the test tube, tipranavir has been shown to have effects on platelet clumping similar to those of aspirin. Platelets are blood elements important for blood clotting (stopping bleeding).

Patients taking APTIVUS should not discontinue or modify their treatment with APTIVUS or any other medication, without first consulting their doctor to discuss the most appropriate therapy for their individual treatment needs.

The Product Monograph for APTIVUS is in the process of being updated to reflect this new safety information. Boehringer Ingelheim has also issued a letter to health professionals advising them of this new safety information.

A copy of the letter to health professionals and this communication will be posted on Boehringer Ingelheim's www.boehringer-ingelheim.ca and Health Canada's web site.

Managing marketed health product-related adverse reactions depends on health care professionals and consumers reporting them. Reporting rates determined on the basis of spontaneously reported post-marketing adverse reactions are generally presumed to underestimate the risks associated with health product treatments. Any case of intracranial bleeding or any other serious adverse event occurring in patients receiving APTIVUS should be reported to Boehringer Ingelheim or Health Canada at the following addresses:
