Study Description

Brief Summary:

To test and evaluate the efficacy and safety of intravenous cidofovir (Vistide, previously known as HPMPC) for the treatment of retinitis.

Condition or disease	Intervention/treatment	Phase
HIV Infections; CMV Cytomegalovirus Retinitis	Drug: Cidofovir	Phase 2; Phase 3

Detailed Description:

CMV (cytomegalovirus) retinitis is the most common intraocular infection in patients with AIDS and is estimated to affect 35 percent to 40 percent of patients with AIDS. Untreated CMV (cytomegalovirus) retinitis is a progressive disorder, the end result of which is total retinal destruction and blindness. As of September 1997, drugs approved by the United States Food and Drug Administration (FDA) for the treatment of CMV (cytomegalovirus)retinitis were ganciclovir (Cytovene), foscarnet (Foscavir), and cidofovir (Vistide). Cidofovir has a prolonged duration of effect permitting intermittent administration. All systemically administered anti-CMV drugs are given in a similar fashion consisting of initial 2-week high-dose treatment (induction) to control the infection followed by long-term lower dose treatment (maintenance) to prevent relapse. Cidofovir is administered as an intravenous infusion once weekly for induction therapy and once every 2 weeks as maintenance therapy. The HPCRT evaluated the efficacy and safety of cidofovir therapy.

The HPCRT was a multicenter, randomized, controlled clinical trial of cidofovir for the treatment of CMV (cytomegalovirus) retinitis. Patients with small peripheral CMV (cytomegalovirus) retinitis lesions (i.e., not at risk of immediate loss of visual acuity) were randomized to immediate treatment with cidofovir or deferred therapy until the retinitis had progressed. Patients randomized to immediate therapy received either 1) low-dose cidofovir at 5 mg/kg once weekly induction for 2 weeks, followed by 3 mg/kg once every 2 weeks for maintenance or 2) high-dose cidofovir at 5 mg/kg once weekly induction for 2 weeks followed by 5 mg/kg once every 2 weeks for maintenance. Patients whose retinitis progressed were given treatment according to best medical judgement, and those assigned to deferral were generally treated with cidofovir.

Outcomes in this trial included retinitis progression, loss of retinal area, and morbidity.

• 13 years or older
• Diagnosis of CMV (cytomegalovirus) retinitis as determined by a SOCA-certified Ophthalmologist.
• At least one lesion whose size is one-quarter disc area or more that can be photographed.
• Visual acuity in an affected eye of 3 or more lines on the (ETDRS) Early Treatment Diabetic Retinopathy Study chart at 1 meter distance (Snellen equivalent 8/200).
• score of 60 or more on the Karnofsky scale.
• Serum creatinine of 1.5mg/dL or less
