SOFT GELATIN CAPSULES
FORTOVASE brand of saquinavir is an inhibitor of the human immunodeficiency virus (HIV) protease. FORTOVASE is available as beige, opaque, soft gelatin capsules for oral administration in a 200-mg strength (as saquinavir free base).
FORTOVASE is indicated for use in combination with other antiretroviral agents for the treatment of HIV infection. This indication is based on studies that showed increased saquinavir concentrations and improved antiviral activity for FORTOVASE 1200 mg tid compared to INVIRASE 600 mg tid.
In treatment-naive and treatment-experienced patients, the efficacy of FORTOVASE (with or without ritonavir coadministration) has not been compared against the efficacy of antiretroviral regimens currently considered standard of care.
When used in combination with other antiretroviral agents, FORTOVASE and INVIRASE have been shown to decrease plasma HIV RNA levels and increase CD4 cell counts in an open-label randomized study (NV15355) in treatment-naive, HIV-infected patients. In addition, in a randomized, double-blind study (NV14256) in ZDV-experienced, HIV-infected patients, a combination regimen of FORTOVASE and HIVID was shown to be superior to either INVIRASE or HIVID monotherapy in decreasing the cumulative incidence of clinical disease progression to AIDS-defining events or death. It should be noted that HIV treatment regimens that were used in the initial clinical studies of INVIRASE are no longer considered standard of care.
FORTOVASE 1000 mg bid coadministered with ritonavir 100 mg bid was studied in a heterogeneous population of 148 HIV infected patients (MaxCmin 1 study). At baseline 42 were treatment naive and 106 were treatment experienced (of which 52 had an HIV RNA level <400 copies/mL at baseline). Results showed that 91/148 (61%) subjects achieved and/or sustained and HIV RNA level <400 copies/mL at the completion of 48 weeks.
Study NV15182 was an open-label safety study of FORTOVASE in combination with other antiretroviral agents in HIV-infected patients. The 48-week safety results from this study are displayed in the ADVERSE REACTIONS section.

Bioequivalence study of two oral tablet formulations containing tenofovir disoproxil fumarate in healthy volunteers. 
Tenofovir disoproxil fumarate (TDF, CAS 147127-20-6) is a nucleotide reverse transcriptase inhibitor which is indicated in combination with other antiretroviral agents for the management of HIV-1 infection. The objective of this study was to compare the rate and extent of absorption and to assess the bioequivalence between a new pharmaceutical equivalent tablet formulation containing 300 mg of TDF and the innovator product...
Saquinavir/ritonavir monotherapy as a new nucleoside-sparing maintenance strategy in long-term virologically suppressed HIV-infected patients. [2010.09.01]
BACKGROUND: The high antiviral potency and low toxicity of saquinavir/ritonavir (SQV/r) prompted us to assess a viable strategy in chronic virologically suppressed HIV-infected patients... CONCLUSION: SQV/r as monotherapy has proven to be a valid, safe, and economical option for virologically suppressed HIV-infected patients, especially in those who experience intolerance or toxicity with nucleoside analogs.
Gemini: a noninferiority study of saquinavir/ritonavir versus lopinavir/ritonavir as initial HIV-1 therapy in adults. [2009.04.01]
INTRODUCTION:: Direct comparison of the efficacy and safety of different agents is needed to guide selection of optimal treatment regimens for therapy-naive HIV-1-infected patients... CONCLUSIONS:: In treatment-naive, HIV-1-infected patients, SQV/r treatment was noninferior in virologic suppression at 48 weeks to LPV/r treatment and offered a better triglyceride profile.
Pharmacokinetics and safety of saquinavir/ritonavir and omeprazole in HIV-infected subjects. [2008.06]
We investigated the pharmacokinetics and safety of saquinavir/ritonavir when administered with omeprazole simultaneously and 2 h apart to human immunodeficiency virus (HIV) subjects. Saquinavir/ritonavir 12-h pharmacokinetics was assessed with and without omeprazole 40 mg... In the presence of omeprazole, saquinavir plasma exposure is significantly increased in HIV-infected subjects whether administered simultaneously or 2 h apart.
