US FDA Expands Approval Of Roche Hemophilia Drug

Roche is counting on new medicines like Hemlibra to replace falling revenue from its trio of blockbuster cancer medicines, Rituxan, Avastin and Herceptin.

ROCHE, RECENTLY received an US regulators approval for expanded use of its drug Hemlibra to include almost all patients with hemophilia A, as the Swiss drugmaker increases its focus on diseases beyond cancer to help replace revenue from older products that have lost patent protection.

The Food and Drug Administration cleared Hemlibra to treat adults, children and newborns with the genetic disorder in which blood does not clot properly, putting them at risk of dangerous bleeding.

Hemlibra can now be used for patients who have not become resistant to standard treatment, known as factor replacement therapy. It is the only preventive treatment for hemophilia A patients with and without factor VIII inhibitors that can be self-administered subcutaneously once weekly, every two weeks or every four weeks. Older treatments, sold by companies like Shire, require more frequent intravenous infusions.

Hemlibra won initial US approval last year only for hemophilia A patients with factor VIII resistance, or inhibitors. That accounted for only about 5 per cent to 7 per cent of the estimated 16,000 US hemophilia A patients. Factor VIII is a protein involved in clotting.

For a hemophilia A patient of average weight of about 140 pounds (63.4 kg), the annual list price for Hemlibra will be about $ 492,000 per year, following the initial first-year dose that costs an additional $ 38,000, a spokeswoman for Roche’s US Genentech unit said on Thursday. Dosing is based on a patient’s weight.
