Roche To Stop Antiretroviral Research, Company Says

Pharmaceutical company Roche in a memo circulated last week announced that it will stop research on antiretroviral drugs because of "disappointing results in clinical trials," the Financial Times reports. According to the memo, which was sent to HIV/AIDS specialists and advocates, Roche has canceled its program to research compounds that were targeting two different ways to attack HIV. The company stressed that it will continue to manufacture its current antiretrovirals -- Fuzeon, Viracept and Invirase -- as well as its HIV diagnostic test and other treatments related to the disease.
