Initiation of enrollment into the expanded access program -- which will be for heavily treatment-experienced adults living with HIV/AIDS -- is contingent on the approval of local health authorities and recruitment of pivotal phase III trials. Expanded access programs provide people with severe or life-threatening illnesses with access to treatments currently being evaluated in clinical trials.
"We know that many people living with HIV/AIDS have run out of treatment options because of the increasingly significant issue of viral resistance, and we are working to provide them with access to TMC114 as soon as possible through this program," said Paul Stoffels, M.D., President of Tibotec.
TMC114 belongs to a class of antiretroviral agents known as protease inhibitors. Protease inhibitors are commonly used in combination with other classes of anti-HIV drugs to prevent the replication of HIV in the body.
After 24 weeks, the percentage of patients reaching undetectable virus levels (<50 copies/ml) ranged from 30% (lowest dose group) to 47% (highest dose group) in the TMC114/RTV arms, compared with 10% in the control arm. The most common adverse events were headache and diarrhea, which were 17% and 14% respectively across all TMC114/RTV arms compared with 23% and 20% in the control arm. These studies will continue to 144 weeks.
Based on these 24-week results, the selected dose of TMC114/RTV for treatment-experienced patients in phase III trials is 600mg/100mg BID. TMC114 will be studied in both treatment-experienced and -naive patients in phase III trials.
