Filter by:To make intravenous (IV) ganciclovir available to immunocompromised patients with life-threatening or sight-threatening Cytomegalovirus (CMV) infection, where the symptoms of the disease are too severe to allow admission to a controlled clinical study of ganciclovir therapy. To determine the safety and tolerance of 2 - 3 weeks induction course of ganciclovir IV followed by a maintenance course of ganciclovir IV for an indefinite duration. To tabulate the patient's clinical response.
To provide ganciclovir on a compassionate use basis to immunocompromised patients with serious cytomegalovirus (CMV) infections and to study safety and efficacy in this patient population.
To determine the maximum tolerated dose (MTD) and toxicity of sargramostim (recombinant granulocyte-macrophage colony-stimulating factor; GM-CSF) given by continuous intravenous infusion (CIV) in patients with leukopenia in association with AIDS virus infection. In addition, single dose and steady state pharmacokinetics will also be determined.
To determine the safety, immunogenicity, biological activity, ad pharmacokinetics of sargramostim ( recombinant granulocyte-macrophage colony-stimulating factor; GM-CSF ) human granulocyte-macrophage colony-stimulating factor ( GM-CSF ), given by subcutaneous ( SC ) injection to patients with leukopenia in association with HIV infection.
To evaluate the safety of repeated courses of sargramostim ( recombinant granulocyte-macrophage colony-stimulating factor; GM-CSF ) administered subcutaneously to patients with HIV infection and leukopenia. To determine if administration of GM-CSF will prevent some or all of the hematologic toxicity associated with zidovudine ( AZT ) treatment in patients with pre-existing leukopenia. To assess any clinical and/or virologic benefits from administering alternating weeks of GM-CSF and AZT to patients with symptomatic HIV infection who have a history of cytologically confirmed Pneumocystis carinii pneumonia ( PCP ) or a circulating absolute CD4 lymphocyte count less than 200 cells/mm3.
To assess the safety and efficacy of subcutaneously administered sargramostim ( granulocyte-macrophage colony-stimulating factor; GM-CSF ) in increasing and maintaining the neutrophil count in HIV-infected adults who have developed neutropenia as a result of receiving the antiretroviral agent, zidovudine ( AZT ). To assess the safety and efficacy of subcutaneously administered GM-CSF in increasing and maintaining the neutrophil count in HIV-infected adults with pre-existing neutropenia who are at high risk of developing hematologic intolerance while receiving the antiretroviral agent, AZT, for the first time. To assess the potential therapeutic benefit of concomitant GM-CSF and AZT on the natural history of HIV infection and associated infectious complications.
To evaluate the safety and efficacy of oral valacyclovir hydrochloride (256U87) vs. acyclovir in the treatment of recurrent anogenital herpes in HIV-infected patients (CD4 greater than or equal to 100).
To determine if a drug regimen containing rifabutin will eradicate or decrease the numbers of Mycobacterium avium complex (MAC) organisms in blood, improve the symptoms associated with MAC infection, and increase survival in patients with AIDS. To assess the safety of the drug regimen.
This study will evaluate the reliability of a new test called Real-Time Polymerase chain reaction (RT PCR) in detecting cytomegalovirus (CMV) in the blood and predicting the course of CMV disease in patients who have recently had a bone marrow transplant. The test's effectiveness will be compared with that of the "pp65 antigenemia assay" now routinely used for this purpose. CMV is a common virus that is transmitted from person to person by close personal contact. In most healthy people, CVM can remain in the body indefinitely without causing any harm. But, in people with weakened immune systems-including those who have just undergone bone marrow transplant-CMV infection can cause serious, and possibly fatal, complications. Drugs are available to treat this infection, however. Optimum treatment depends on early and accurate detection. Patients aged 10 to 80 years who are scheduled to undergo bone marrow transplant at the NIH Clinical Center as part of an NIH protocol may be eligible for this 2-phase study. In phase 1, patients will have blood drawn for both RT PCR and antigenemia testing once before the bone marrow transplantation and then weekly for the first 100 days after the transplant. During Phase 2-which begins immediately after the end of phase 1 and continues for one year after the transplant-blood samples for both tests will be drawn up to once a week. The samples for both tests will be collected at the same time and will be taken through a catheter (a thin flexible tube inserted into a vein) that has already been placed for the transplant study. RT PCR testing will require an extra 5 milliliters (1 teaspoon) above what is needed for antigenemia testing, amounting to a maximum of about one-half pint extra over the course of the 1-year study. It is hoped that the new RT PCR test will prove to be more accurate in detecting CMV infection and predicting disease development, thus enabling doctors to plan early and effective treatment.
This study will test the safety and effectiveness of a drug called interleukin-12 (IL-12) in fighting severe infectious (other than tuberculosis) caused by a group of bacteria called mycobacteria. IL-12 is similar to a substance the body produces naturally to strengthen immune function (infection-fighting ability). It works by stimulating white blood cells to increase production of a chemical called interferon gamma, which can improve or cure mycobacterial infections in some patients. In previous studies, IL-12 has improved immune function against mycobacteria in test tube experiments and in mice. A recent study of three patients with mycobacterial infections treated with the drug showed encouraging results. The drug has also been studied more extensively in patients with cancer, HIV infection and hepatitis C. Patients in this study will receive IL-12 injections under the skin twice a week for one year. They will be taught how to self-administer the drug, but a home care nurse or a physician may also give the injections. The drug dosage will be increased each week to determine the safest and most effective dose for fighting this infection. If intolerable side effects develop at a certain dose, the previous dose level will be used for the next injection. That dose will then be used for the rest of the study, unless unacceptable side effects develop at that level, in which case the dose will again be lowered. Patients will receive an antibiotic against mycobacteria. Physical examinations and blood and urine tests will be done once a month for at least the first year and then every 3 months the following year to evaluate kidney, liver, and immune function. The first evaluation-at the start of the study-is done on an inpatient basis.
