This double-blind, placebo-controlled, dose-finding study is designed to identify the lowest AGI-1067 dose that improves glycemic control as measured by HbA1c and fasting glucose in subjects with Type 2 diabetes mellitus. Glycemic control will be measured during a 6-month treatment period in subjects who are on 1 or no antidiabetic drugs
PCI (optimal catheter-based coronary revascularization) + intensive medical therapy is superior to intensive medical therapy alone using the combined endpoint of all-cause mortality or nonfatal MI.
This study will determine if medical treatment of colitis (inflammation of the colon resulting in loose bowel movements, rectal bleeding, and belly pain) that is used for other colitis conditions, such as Crohn's disease and ulcerative colitis, is safe and effective for treating colitis in patients with Hermansky-Pudlak syndrome (HPS). HPS is a hereditary disorder that causes albinism, visual impairment, and abnormal bleeding. Some patients also develop colitis, pulmonary fibrosis, and kidney disease. Patients with HPS and colitis who are 18 years of age or older may be eligible for this study. Participants receive treatment for their colitis symptoms with one or more of several study drugs, which include mesalamine (5-ASA), corticosteroids, infliximab and 6-mercaptopurine, adalimumab and tacrolimus. The drugs are added to the treatment plan one at a time to find the combination that works best for the individual patient. Patients who respond to one or more of the medications may continue treatment with that same combination for up to 6 months. Regular clinic visits are scheduled for blood tests, symptoms ratings questionnaires and periodic physical examinations and colonoscopies to measure the response to treatment and evaluate any side effects.
The purpose of this study is to see if it is safe and effective to treat cryptosporidiosis in AIDS patients with nitazoxanide.
To evaluate the effect of Isoprinosine in patients diagnosed as having AIDS relative to: Laboratory (immunologic defects): * Comparison of total helper and suppressor T-cell numbers among the groups. * Comparison of changes in natural killer cell activity. * Comparison of other laboratory findings among the groups. Clinical changes: * Comparison of the frequency of opportunistic infections among the groups. * Comparison of the frequency of the development of AIDS-related malignancies. * Comparison of other clinical manifestations relative to severity and time of onset.
To determine the safety and efficacy of zidovudine (AZT) treatment combined with syngeneic or HLA identical allogeneic lymphocyte transfer in the presence of interleukin 2 (IL-2) as a treatment for AIDS. Patients with documented HIV viremia will be evaluated. Effects on virus replication, immune function, and clinical condition will be monitored with periodic virus cultures, estimates of lymphocyte type and numbers, cell surface markers, in vitro lymphocyte responses and frequent clinical evaluations.
To study the effectiveness of alpha interferon (IFN-A2b) and zidovudine (AZT) in treating progressive multifocal leukoencephalopathy (PML) as a complication of HIV-1 infection.
To determine the safety, tolerance, and potential in vivo antiviral effects of five dosage levels and a dose to be determined of human anti-cytomegalovirus (CMV) monoclonal antibody (SDZ MSL-109; formerly SDZ 89-109) when administered once every 2 weeks for a total of 12 doses to patients with either AIDS or eligible AIDS-related complex (ARC) and with culture proven evidence of CMV viremia and/or viruria. Sandoglobulin will be employed as a comparative control.
To demonstrate that zalcitabine (dideoxycytidine; ddC) monotherapy is safe and tolerable in the treatment of patients with AIDS or advanced AIDS related complex (ARC) who previously demonstrated intolerance to zidovudine (AZT) treatment while in Protocol N3300 (NIAID ACTG 114) or N3492 (NIAID ACTG 119). NOTE OF CAUTION FOR CONCOMITANT MEDICATIONS ON STUDY: Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole, ganciclovir, intravenous pentamidine, intravenous acyclovir or oral acyclovir or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent clinical and laboratory assessments, as appropriate. Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might be expected to cause increased toxicity when co-administered with ddC. Drugs that could cause serious additive toxicity when co-administered with study medication will be allowed for treatment of an acute intercurrent illness or opportunistic infection at the discretion of the investigator. Their use may be allowed with interruption of study drug for up to 35 days per episode, for a total of 90 days for the study. If the patient's condition requires chronic administration of these medications, the patient will be discontinued from study medication and followed.
To test the effectiveness of recombinant human CD4 Immunoglobulin G (CD4-IgG) in the treatment of HIV-associated immune thrombocytopenic purpura in patients with all levels of HIV infection.
To determine the safety and tolerance of subcutaneous injections of natural interferon alpha (IFN) in asymptomatic HIV-positive persons and record its effects on the HIV virus in these individuals.
The purpose of this pilot study is to evaluate the efficacy of Retrovir (AZT) in the treatment of AIDS-related dementia and various neuromuscular complications. HIV is both a lymphotropic and neurotropic virus which can affect both the central and peripheral nervous systems (CNS, PNS). There is evidence that the CNS and PNS may harbor the virus in a latent state, with the potential for continuous reinfection of other body systems. Therefore, effective therapeutic efforts against HIV infection should provide effective antiviral activity within the nervous system.
To determine the safety and tolerance of various combinations of zidovudine (AZT) and didanosine (ddI) administered concurrently. To determine the pharmacokinetics of concurrent AZT and ddI administered orally. To evaluate the antiviral, immunologic and virologic effects of AZT and ddI administered concurrently.
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 test the safety and immunogenicity of rgp 120/HIV-1IIIB vaccine in HIV-1 seropositive adult patients.
This study involves GLQ223 administration to patients who have not previously been exposed to it, but who have received at least 9 months of zidovudine therapy. Efficacy evaluations will include survival, opportunistic infections, T4 cell count, and assessments of viral load.
To evaluate the safety and toxicity of combination therapy for AIDS-associated Kaposi's sarcoma with zidovudine (AZT) and two kinds of interferon alpha. The two kinds are interferon alpha (IFN-A) and interferon alpha-2A (recombinant) (IFN-A2A). To define the pharmacokinetics of AZT and IFN-A or AZT and IFN-A2A when given in combination. To define the maximum tolerated dose (MTD) of each drug in combination and to define doses to be used in Phase II trial. AZT has been found to be effective against the effects of HIV in vitro (test tube) and both interferons have shown antiviral and antitumor effect on Kaposi's sarcoma. It is reasonable to assume that a synergism and an enhanced antitumor response may be seen with combination therapy. A study to evaluate the safety and effectiveness of AZT in the combination with IFN-A2A is warranted.
To find out which of four doses of (recombinant) human interferon gamma (IFN-G) is most effective in stimulating the white blood cells (monocytes) to fight infection and to see if treatment with IFN-G can strengthen the ability of AIDS patients to control infections. This study will also determine how long after a single injection of IFN-G white blood cells remain stimulated. AIDS is a disease that progressively destroys that aspect of the body's defense called the immune system. It is particularly harmful to a class of cells called helper T-lymphocytes. The specific opportunistic infections and malignancies associated with AIDS have been treated with therapies that are often poorly tolerated by the patients and are associated with dose-limiting toxicities. The principal focus of AIDS therapy research at present is to control the underlying retroviral infection and to restore immune function with recombinant lymphokines, adoptive immunotherapy, and/or lymphocyte transplants. These treatments include zidovudine (AZT), which has been shown to control the HIV infection, and IFN-G, a lymphokine which activates tumor-destroying and germ-killing functions. Studies are needed to find the dose by which IFN-G works best.
AMENDED: To evaluate the pharmacokinetics of intravenously administered AZT to HIV-1 infected pregnant women in labor; to evaluate the pharmacokinetics and urinary excretion of AZT and its metabolites in newborns of HIV-1 infected mothers who receive IV AZT only during labor; to evaluate the safety of IV AZT administered by continuous infusion to HIV-1 infected laboring women and their infants. Original design: To determine the distribution and elimination of zidovudine (AZT) in the body as well as its safety in the treatment of pregnant women and their unborn children. The information derived from this study is required in order to design a future study that will assess the efficacy of AZT in reducing the transmission rate of HIV-1 from seropositive women to their fetus by treating them during the third trimester of pregnancy. An estimated 30 percent to 40 percent infected pregnant women risk transmission of HIV-1 to their infants, whether they be symptomatic or asymptomatic. Zidovudine (AZT) has previously demonstrated its effectiveness as a potent inhibitor of HIV replication in vitro and in adult patients; benefits of treatment include decreased mortality rate, decreased incidence of opportunistic infections, and increased number of CD4 cells. Phase I AZT studies in children, however, have resulted in uncontrolled information regarding clinical efficacy. The present study, therefore, will investigate the safety and pharmacokinetics of intravenous (IV) and oral AZT administration to HIV-1 infected pregnant women in the 3rd trimester, as well as the safety and efficacy of such treatment in their newborns. It is hoped that the results will be instrumental in designing future studies to assess the efficacy of AZT in reducing the transmission risk of HIV-1.
To determine the safety and effectiveness of an investigational drug trimetrexate (TMTX) with leucovorin rescue (LCV) in the treatment of Pneumocystis carinii pneumonia (PCP) in patients who have AIDS, are HIV positive, or are at high risk for HIV infection, and who have demonstrated serious adverse effects from the conventional therapies for PCP. The drugs usually used to treat PCP in AIDS patients (trimethoprim / sulfamethoxazole and pentamidine) have had to be discontinued in many patients because of severe adverse effects. Currently there are no proven alternatives to these drugs. TMTX was chosen for this trial because it has been found to be very active against the PCP organism in laboratory tests. In a preliminary trial, TMTX in combination with LCV has been effective against PCP with fewer and less severe adverse effects.
To study the tolerance and safety of increasing doses of AL-721 in patients with persistent generalized lymphadenopathy (PGL) and symptomatic HIV infection, and to obtain preliminary information on the effectiveness of AL-721 against the human immunodeficiency virus (HIV) in HIV-infected persons with PGL and symptomatic HIV infection. Although zidovudine (AZT) prolongs life in certain AIDS patients, it is not a cure for AIDS and it also has toxic effects in many patients. Therefore, it is necessary to test other drugs in HIV-infected patients. AL-721 is a mixture of lipids (fats) extracted from egg yolks. Laboratory tests suggest that it might inhibit the infectivity of the HIV. AL-721 has been tried so far in a few patients for short periods of time and has been found to be well tolerated.
To compare the effect of zidovudine (AZT) given alone with the combination of AZT and acyclovir (ACV) on the human immunodeficiency virus (HIV) in persons infected with HIV, and to study the pharmacokinetics (how fast AZT reaches certain levels in blood and how long it remains), safety, and effectiveness of AZT given alone and in combination with ACV in treating HIV-infected patients. Other studies have shown that AZT offers potential benefits to specific AIDS patients when given over long time periods, and experiments in vitro (in the test tube) suggest that ACV may stimulate the action of AZT against HIV. It is necessary to obtain information on how these drugs perform in HIV-infected humans.
To determine the effectiveness and safety of dextran sulfate (DS) as a treatment for patients with AIDS, AIDS related complex (ARC), or asymptomatic HIV infection with or without persistent generalized lymphadenopathy (PGL), and to determine antiviral activity at different doses of DS. Although zidovudine (AZT) has shown promise in prolonging life in patients with AIDS and severe ARC, it has significant blood toxicities. It would be beneficial to combine AZT with another antiviral agent that does not have the same toxicity. DS might be a suitable drug since it has shown antiviral activity against HIV in the laboratory, and in preliminary studies it has shown little toxicity. Also, the combination of DS with AZT has been shown to be more effective than either alone.
To determine if methadone treatment will affect the blood levels of zidovudine (AZT) in patients with AIDS or AIDS-related complex (ARC) who are receiving oral AZT and methadone therapy. In addition, the blood levels of methadone both before and during AZT treatment will be studied, and patients receiving daily oral methadone treatment will be evaluated for signs of narcotic withdrawal during treatment with AZT. The number of deaths due to AIDS in high-risk populations continues to increase. Nationwide approximately 25 percent of AIDS patients are intravenous (IV) drug abusers, and it is very likely that an increasingly larger number of AIDS patients receiving AZT therapy will have had a history of IV drug abuse. The major chemical treatment for IV drug abuse is daily methadone maintenance therapy, and IV drug abusers who are HIV positive represent a large number of patients who will undergo long-term treatment with both methadone and AZT. Therefore, the study of potential drug interactions is essential.
To determine if intravenous (IV) and oral zidovudine (AZT) can be safely given to children aged 1 day to 3 months who were born to mothers with an HIV infection. Also to determine the correct dose of AZT for young children. Of a total of 908 pediatric AIDS cases, 78 percent have acquired HIV infection from a mother with HIV infection or at high risk for acquisition of HIV, and the number of cases in children is expected to increase over the next several years. AZT therapy may be effective in altering the course of the disease and decreasing the high mortality in these children. It is also possible that early intervention with AZT may prevent the establishment of HIV contracted before, during, or just after birth.
To determine the toxic effects of AS-101 at various doses in patients with AIDS or AIDS related complex. Also to determine the effect of various doses of AS-101 on immune functions and the occurrence of infections in these patients. AIDS is a viral disease that is characterized by a loss of some immune function and the development of frequent, eventually fatal, infectious diseases. Although zidovudine (AZT) has prolonged survival in some patients with AIDS, AZT is quite toxic and there is a need for more effective and less toxic drugs. AS-101 is a synthetic organic compound containing the metal tellurium that is being tested because in laboratory studies it improved immune functions.
AMENDED: To investigate whether subcutaneous (SC) injection of IL-2 produces biological responses which parallel those observed with IV dosing. Original design: To evaluate the short-term effects of combined administration of zidovudine (AZT) and increasing doses of recombinant interleukin-2 (aldesleukin; IL-2) in patients infected with HIV, who have lymphadenopathy, but who are otherwise asymptomatic (no other symptoms). The first phase of this clinical trial will establish maximum tolerated dose ( MTD ). How quickly the drugs get into the blood and how long they remain there (pharmacokinetics) will also be studied at each dose as well as the effect on HIV. Since AZT has no effect on cells that contain inactive virus (latently infected cells) and these cells may act as viral reservoirs, that a second agent that can destroy these infected cells would be useful in combination with AZT. The different activities of AZT and IL-2, as well as the non-overlapping nature of their mechanisms of action and toxicity, increase the theoretical benefits of combining AZT, a drug which has clinically significant activity in HIV-related disease but cannot eliminate infected cells, with IL-2, a drug which may enhance anti-HIV immunity, destroy chronically infected cells, and allow immune recognition of latently infected cells.
