Brief Summary
To examine the safety and tolerance of the administration of ganciclovir and foscarnet given together or alternately; to determine the interactive pharmacokinetics (blood level) profile of long-term combined and alternating therapy with these two drugs. Additional objectives are to examine the effect of these treatments in controlling time to cytomegalovirus (CMV) retinitis progression and to examine the antiviral activity of combined and alternating ganciclovir/foscarnet treatment and development of antiviral resistance. Sight-threatening CMV retinitis occurs in at least 6 percent of AIDS patients. By 1991 (US), there may be 6000 to 10000 patients with CMV retinitis. Many clinical reports suggest that both ganciclovir (DHPG) and foscarnet have an antiviral effect against CMV that is often associated with clinical stabilization. Effectiveness of ganciclovir and foscarnet is correlated with weekly maintenance and since toxicity is dose-limiting in up to 20 percent of patients receiving either drug for long periods, it may be beneficial in long-term maintenance treatment to combine or alternate these two drugs at a lower total weekly dose of each drug. This strategy may result in a greater net antiviral effect with less toxicity than is seen with either drug alone, because the toxicities of each drug are quite different.

Eligibility Criteria
You may qualify if:
- Concurrent Medication:
- Allowed:
- Chemotherapy for Kaposi's sarcoma (excluding interferon) if patient is hematologically stable for at least 30 days prior to entry.
- Zidovudine (AZT), dideoxyinosine (ddI), dideoxycytidine (ddC) after first two weeks of study period if absolute neutrophil count is \> 1000 cells/mm3 and hemoglobin = or \> 8 g/dl.
- Vancomycin.
- Fluconazole or investigational triazoles (e.g., itraconazole, SCH 39304) for disseminated fungal infection.
- Pneumocystis carinii pneumonia prophylaxis (except parenteral pentamidine).
- Acyclovir or other appropriate medication may be instituted in the event of the appearance of Herpes simplex virus
- (HSV) or Varicella zoster virus (VZV) infections.
- G-CSF or GM-CSF for grade 4 neutropenia.
- Concurrent Treatment:
- Allowed:
- Recombinant human erythropoietin.
- Prior Medication: Required:
- Completion of 14-day course of intravenous ganciclovir induction therapy (2.5 mg/kg IV q8h or 5 mg/kg q12h for 14 days) or foscarnet induction therapy (60 mg/kg q8h adjusted for renal function for 14 days) within 1 week prior to study entry. Patients who do not initiate the study immediately upon completing ganciclovir induction therapy should receive a maintenance ganciclovir regimen of 5 mg/kg/day or 6 mg/kg/day 5 x week or a foscarnet regimen of 90-120 mg/kg/day until initiating study drug.
- +5 more criteria
You may not qualify if:
- Co-existing Condition:
- Patients with the following conditions or symptoms are excluded:
- Evidence of tuberculous, diabetic or hypertensive retinopathy.
- Osteomalacia, neoplasm metastatic to bone or other bone disease.
- Any clinically significant pulmonary or neurologic impairment (for example, patients who are intubated or comatose).
- Retinal detachment.
- Corneal, lens, or vitreous opacification precluding funduscopic exam.
- Concurrent Medication:
- Excluded:
- Immunomodulators, biologic response modifiers or investigational agents not specifically allowed.
- Aminoglycosides, amphotericin B, probenecid, parenteral pentamidine.
- Zidovudine (AZT), dideoxyinosine (ddI), dideoxycytidine (ddC) until completion of second week of maintenance therapy. ddC use is discouraged but not prohibited because of paucity of experience of this drug with ganciclovir and foscarnet.
- Anti-cytomegalovirus (CMV) therapy:
- Ganciclovir, CMV hyperimmune serum/globulin, interferons, immunomodulators.
- Prophylactic antiviral therapy with acyclovir.
