Abbott Announces Phase 3 Hepatitis C Program Details

About Abbott's HCV Development ProgramsAbbott's HCV portfolio includes investigational medicines with three different mechanisms of action, including protease (ABT-450/r), polymerase (ABT-333) and NS5A (ABT-267) inhibitors, currently being studied in clinical trials. ABT-450 is being developed with low-dose (non-therapeutic) ritonavir which enhances the pharmacokinetic properties of ABT-450. The use of ritonavir 100mg with ABT-450 for the treatment of HCV is investigational.

ABT-450 was discovered during the course of a collaboration between Abbott and Enanta Pharmaceuticals for HCV protease inhibitors and regimens that include protease inhibitors. ABT-450 is being developed by Abbott for use in combination with Abbott's other investigational medicines for the treatment of HCV. Abbott is well-positioned to explore combinations and co-formulations of these medicines.

Ritonavir Use in Treatment of HIVRitonavir is in a class of medicines called the HIV protease inhibitors. Ritonavir is used in combination with other anti-HIV medicines to treat people with human immunodeficiency virus (HIV) infection. Ritonavir is for adults and for children greater than 1 month in age and older.

Ritonavir does not cure HIV infection or AIDS and does not reduce the risk of passing HIV to others. People taking ritonavir may still get opportunistic infections or other conditions that happen with HIV infection. Some of these conditions are pneumonia, herpes virus infections, and Mycobacterium avium complex (MAC) infections.

Ritonavir Safety in Treatment of HIVPatients should not take ritonavir with certain medicines, as these can cause serious or life-threatening problems such as irregular heartbeat, breathing difficulties, or excessive sleepiness. Patients should not take ritonavir if they have had a serious allergic reaction to any of its ingredients. Some patients taking ritonavir may develop liver and pancreas problems, which can cause death.

Patients may develop large increases in triglycerides and cholesterol, diabetes, high blood sugar, changes in body fat, increased bleeding in people with hemophilia, allergic reactions, and/or changes in heart rhythm. Patients may develop signs and symptoms of infections that they already have after starting anti-HIV medicines. For more information, please see the Important Safety Information and Full Prescribing Information for Ritonavir .
