Study Overview
Brief Summary
To evaluate the safety and efficacy of foscarnet induction treatment of cytomegalovirus (CMV) retinitis in AIDS patients who have previously suffered severe dose-limiting ganciclovir-related myelosuppression, who are ineligible for ganciclovir treatment due to myelosuppression or who have clearly failed to have a therapeutic response to ganciclovir therapy. To assess the duration of clinical response. To evaluate the effect on quantitative CMV cultures of blood and urine. To determine the effect on recovery of HIV p24 antigen capture direct from plasma.

- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- •Concurrent Medication:
- •Ganciclovir.
Exclusion Criteria
- •Co-existing Condition:
- •Patients with the following are excluded:
- •Known allergy to foscarnet.
- •Any clinically significant pulmonary or neurologic impairment (e.g., patients who are intubated or comatose).
- •Corneal, lens, or vitreous opacification which precludes examination of the fundi in patients with cytomegalovirus (CMV) retinitis.
- •Concurrent Medication:
- •Acyclovir.
- •Nephrotoxic agent.
- •Patients with the following are excluded:
- •Known allergy to foscarnet.
- •Any clinically significant pulmonary or neurologic impairment (e.g., patients who are intubated or comatose).
- •Corneal, lens, or vitreous opacification which precludes examination of the fundi in patients with CMV retinitis.
- •Prior Medication:
- •Excluded within 7 days of study entry:
- •Immunomodulators.
- •Biologic response modifiers.
- •Investigational agents.
- •AIDS patients experiencing cytomegalovirus (CMV) retinitis may be enrolled if they meet one of the following criteria:
- •Myelosuppression:
- •Previously suffered severe dose-limiting ganciclovir-related myelosuppression, or are ineligible for ganciclovir treatment due to myelosuppression.
- •Ganciclovir treatment failure:
- •Clearly failed to have a therapeutic response to ganciclovir therapy.
- •Patients must be able to give informed consent.
- •Patients presenting with a baseline absolute neutrophil count < 750 cells/mm3 or baseline platelet count < 50000 platelets/mm3 will be categorized as ineligible to receive ganciclovir induction therapy and will be allowed to enter the study.
- •Patients who enter the study because of ganciclovir toxicity will have received ganciclovir therapy which resulted in either absolute neutrophil count falling to < 750 cells/mm3 or platelet count falling to < 50000 platelets/mm3 on two separate occasions during either
- •1) a ganciclovir induction regimen of 7.5 mg or less ganciclovir/kg/day in divided doses or 2) a maintenance regimen of 5 mg or less ganciclovir/kg/day as a single dose.
- •Patients who enter the study because of ganciclovir treatment failure will meet one of the following criteria:
- •1) CMV retinitis progression as defined in section V.C.1., i.e., has occurred either at the end of a 10 - 21 day induction course of ganciclovir (7.5 - 10.0 mg/kg/day in divided doses) or 2) during the first 28 days of maintenance ganciclovir therapy (5 or more mg/kg/day in at least 5 days/week) where maintenance therapy began within
- •week of completing induction therapy.
