Brief Summary:

The purpose of this study is to make valganciclovir available, before it is approved for marketing, to HIV-infected patients who have cytomegalovirus (CMV) retinitis (eye infection) and cannot take drugs by injection. This study also will look at the safety of using valganciclovir as starting and/or ongoing therapy.

CMV can cause serious AIDS-related infections in patients with HIV. Drugs that are effective against CMV eye infections can be given only by injection; this calls for a thin tube to be placed into a vein in the chest so that the patient is not put through getting too many needle sticks. An experimental drug, valganciclovir, is similar to 1 of these approved drugs, ganciclovir, but is more convenient and easier to use since it can be taken by mouth. Once in the body, valganciclovir changes to ganciclovir. Studies have shown that valganciclovir tablets can result in the same level of ganciclovir in the blood as ganciclovir injection.

Condition or disease Intervention/treatment Phase
Cytomegalovirus Retinitis HIV Infections Drug: Valganciclovir Phase 3

Detailed Description:

CMV causes sight- or life-threatening opportunistic infections in people with AIDS. Intravenous agents including ganciclovir, foscarnet, and cidofovir are presently approved as treatments for CMV retinitis within this population. Ganciclovir and foscarnet induction and maintenance therapy require daily infusions and usually require the use of long-term indwelling central venous catheters. Although the treatment interval of cidofovir is longer, administration necessitates the use of pre-hydration and probenecid in order to avoid a risk of renal toxicity. Oral ganciclovir is an alternative to the intravenous formulation for the maintenance treatment of CMV retinitis. However, because blood levels achieved after oral ganciclovir are low compared to intravenous, oral ganciclovir cannot be used for induction therapy. In an attempt to improve the bioavailability of ganciclovir, valganciclovir was developed. Valganciclovir is a ganciclovir prodrug which, when administered orally, is rapidly converted to the active compound ganciclovir during a first-pass process, with the majority of hydrolysis occurring pre-systemically. Studies have shown that valganciclovir tablets allow systemic exposure of ganciclovir comparable to that achieved with recommended doses of intravenous ganciclovir.

Patients undergo an ophthalmologic exam by an ophthalmologist and safety and other laboratory tests to establish eligibility. No specific visits are requested by the drug usage plan following enrollment; however, patients should be seen for safety and/or clinical assessments and medication dispensation at periodic visits, consistent with standard of care. An ophthalmologic exam should be performed again at Week 3 (no later than Week 4), at the end of the induction treatment phase consistent with standard of care in order to ensure adequate response to therapy. Valganciclovir is provided on a monthly basis and only as long as the patient is assessed and information provided in a timely manner. This supply will be terminated 1 month subsequent to when the drug is available by prescription, unless otherwise decided.
