Pfizer Inc. (PFE) and Mylan Inc. (MYL) agreed to lower the prices on medicines for patients with drug-resistant HIV in developing countries, President Bill Clinton and the companies announced.

The medicines and prices will be available to governments that are members of the William J. Clinton Foundation's Procurement Consortium in Africa, Asia, Latin America and the Caribbean.

Pfizer has committed to lowering the price on its drug to treat tuberculosis in patients taking second-line antiretroviral therapies for HIV/AIDS patients that have developed resistance to first-line remedies by 60% to $1 a dose.

Mylan will make available its four second-line antiretroviral treatments - Atazanavir, Ritonavir, Tenofovir and Lamivudine - in three pills for $475 a year. Next year the pills will be packaged together, allowing a price cut to $425. In addition to reducing the number of pills taken per day, the products will include the first heat stable-version of Ritonavir, eliminating the need for refrigeration, removing a major obstacle to distributing the drug in developing countries with limited infrastructure.

It is the first time the combination has been available for less than $500 a year, the announcement said. If fully adopted the new regimen could lead to a cumulative cost savings of $400 million over the next five years compared with recent prices for alternative treatments.

There were between 200,000 and 250,000 HIV drug-resistant patients across the developing world last year. The number is expected to double over the next three years, the announcement said.
