Ritonavir, also known as Norvir, is a type of medicine called a protease inhibitor (PI). PIs act by blocking protease, a protein that HIV needs to make more copies of itself. Ritonavir was approved by the FDA on March 1, 1996, for use with other antiretroviral agents in the treatment of HIV infection in adults and children 2 years of age or older. Ritonavir is now approved with other anti-HIV drugs in the treatment of HIV-1 infection in children in individuals over 1 month in age. Studies have shown that ritonavir works as a booster for some other PIs. Taking ritonavir makes it possible to take a lower dose of the other PIs. This medicine does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people.

Merck today announced plans to initiate a Phase II investigational proof-of-concept clinical study to evaluate its oral antifungal agent posaconazole for the treatment of chronic Chagas disease. Chagas disease results from infection with the parasite Trypanosoma cruzi that is spread by biting insects. The disease is estimated to affect approximately eight million people in Latin America, of whom approximately 30-40 percent will develop serious cardiac disease, digestive disease, or both as a result of this infection.

Bristol-Myers Squibb Company and Otsuka Pharmaceutical Co., Ltd. today announced four-year follow-up results from a Phase 3 randomized, open-label, dose-optimization study of SPRYCEL® (dasatinib) in chronic-phase chronic myeloid leukemia (CML-CP) patients resistant or intolerant to Gleevec®* (imatinib mesylate). At four years, for all patients administered SPRYCEL 100 mg once daily, overall survival was 82% (95% CI: 76%-88%) and progression-free survival was 66% (95% CI: 57%-74%).
Preliminary findings from a unique study with sunitinib suggest that it might be possible to tweak the dosage of chemotherapy drugs used to treat HIV-positive cancer patients to achieve therapeutic benefit. Given the type of drug cocktail patients use to treat their HIV, much more or considerably less chemotherapy may be warranted, say the researchers, part of the NCI-supported AIDS Malignancy Consortium (AMC). The trial design is being presented at the 2010 annual meeting of the American Society of Clinical Oncology (ASCO).
Merck announced today results from a new non-inferiority trial of an antiemetic regimen containing fosaprepitant dimeglumine administered as a single intravenous (IV) 150-mg dose in combination with a 5-HT3 antagonist and dexamethasone compared with a three-day regimen of aprepitant with a 5-HT3 antagonist and dexamethasone for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving a first cycle of cisplatin-based chemotherapy.
Sanofi-aventis announced today the initiation of a multinational, randomized double-blind Phase IIIb trial, PALLAS, to assess the potential clinical benefit of Multaq(R) (dronedarone) in over 10, 000 patients with permanent atrial fibrillation (AF) to reduce major adverse cardiovascular events.
