NCT00023400
Primary Objective: To define the impact of nelfinavir (given at 1250mg bid as part of a combination antiretroviral regimen) on peak levels and area under the curve for rifabutin and the rifabutin metabolite, 25-O-desacetyl rifabutin when rifabutin is given at 300 mg bi-weekly as part of tuberculosis chemotherapy. Secondary Objectives: To compare the pharmacokinetics of nelfinavir given twice daily at 1250 mg bid with twice-weekly isoniazid and rifabutin to the pharmacokinetics of nelfinavir 1250 mg twice-daily in historical HIV-infected patients not receiving isoniazid and rifabutin. To evaluate the correlation between pharmacokinetic parameters of rifabutin and 25-O-desacetyl rifabutin and the occurrence of toxicity attributed to rifabutin in patients with HIV-related tuberculosis. To define detailed pharmacokinetics of isoniazid given at 15mg/kg or 900 mg in patients with HIV-related tuberculosis. To attempt to derive optimal sampling times for nelfinavir and rifabutin pharmacokinetic studies.
NCT00002447
The purpose of this study is to compare 2 anti-HIV drug combinations.
NCT00051766
The purpose of this study is to evaluate the effectiveness of a computer-assisted, self-administered adherence program for patients on complicated anti-HIV drug regimens.
NCT00002310
To evaluate the safety and tolerance of topically applied SP-303T in AIDS patients. To observe the effect of this drug on herpes simplex virus lesions in patients who have failed to heal in response to oral or intravenous acyclovir therapy. The lack of alternative treatments for herpes simplex virus infection in patients with AIDS and the development of resistance to acyclovir for patients requiring repeated treatment presents a therapeutic dilemma for physicians. SP-303T has good in vitro activity against resistant strains and offers a convenient and inexpensive means of drug administration in comparison to the use of intravenous medication.
NCT00002187
The purpose of this study is to compare the safety and effectiveness of two dosage schedules for ISIS 2922 in the treatment of advanced cytomegalovirus (CMV) retinitis
NCT00002058
This study will examine the effectiveness of clofazimine in the prophylaxis of Mycobacterium avium complex infection in HIV infected individuals who are at risk to develop this untreatable opportunistic disease. In the absence of truly effective antiretroviral therapy, a potential mode of treatment of patients with HIV infection is to prevent the development of the life-threatening opportunistic infections. Current studies demonstrate a possible efficacy of clofazimine in the prophylaxis against Pneumocystis carinii pneumonia (PCP), the most common AIDS-defining opportunistic infection. Future studies will examine the potential for prophylaxis against the other opportunistic infections. This proposal hopes to define the role of prophylactic clofazimine in preventing the currently untreatable Mycobacterium avium complex infection. AMENDED: To include prophylaxis for Asymptomatic and ARC.
NCT00002069
To determine if ditiocarb sodium (sodium diethyldithiocarbamate; DTC) restores immune and host defense function; if DTC ameliorates the AIDS related complex (ARC) symptoms in patients with AIDS and ARC; if DTC prevents progression from ARC to AIDS or progression of AIDS; and if DTC prolongs survival in AIDS.
NCT00002332
To evaluate the mechanism whereby thymopentin appears to retard the progressive immune suppression attributable to HIV infection.
NCT00004582
The purpose of this study is to see if ABT-378/ritonavir plus efavirenz is safe and effective in lowering the amount of HIV in the blood of patients who have been treated with more than 1 protease inhibitor (PI).
NCT00002389
To compare the durability of the viral load response following 48 weeks of treatment with 1592U89/lamivudine (3TC)/zidovudine (ZDV) versus 3TC/ZDV alone. To compare the early antiviral activity following 16 weeks treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone as demonstrated by the proportion of subjects with viral load \< 400 copies/ml, plasma HIV-1 RNA profiles and CD4+ profiles. To assess the safety and tolerance following 16 and 48 weeks of treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone.
NCT00000155
To describe the clinical course of keratoconus and to describe the relationships among its visual and physiological manifestations, including high- and low-contrast visual acuity, corneal curvature, slit lamp biomicroscopic findings, corneal scarring, and quality of life. To identify risk factors and protective factors that influence the severity and progression of keratoconus.
NCT00005012
The purpose of this study is to see if it is effective to give PEG-Intron (PEG-IFN) to HIV-infected patients who are not doing well with their current anti-HIV drug combination (HAART).
NCT00037128
Lupus flares and other symptoms associated with systemic lupus erythematosus (SLE) may be caused by a deficiency of dehydroepiandrosterone (DHEA). GL701 is an investigational new drug meant to enhance DHEA levels. This study is designed to evaluate both the safety and efficacy of GL701 in male lupus patients.
NCT00131313
This research study measures the safety and efficacy of the combination of three drugs that are approved, Nipent, Rituxan and Cytoxan in the treatment of Chronic Lymphocytic Leukemia (CLL). These drugs are being given together for investigational purposes as the specific combination of these three drugs has not been approved for treatment of CLL by the FDA.
NCT00127751
The primary objective of this study was to evaluate the effectiveness of a multifactor cardiovascular disease (CVD) risk reduction program using team case management in high risk patients who have low family incomes and limited access to medical care. Patients were randomized to case management (99) or usual care (49) with baseline, 6-month and 12-month evaluations of CVD risk factors, clinical status and quality of life.
NCT00049803
The initial portion of the protocol involves discontinuing any medications for cataplexy that the patient may be taking. Subsequently, the patient is prescribed a dose of oral solution of study drug or placebo over a 10-11 week period. During the trial, narcolepsy symptoms will be evaluated. Participants are allowed to continue using stimulant medications at constant doses during the study. A total of 1 to 3 daytime visits in addition to 4 overnight visits to the sleep center will be required to complete the study.
NCT00032279
The purpose of this phase II study is to evaluate an investigational monoclonal antibody for the treatment of glucocorticoid-refractory Graft Versus Host Disease (GVHD). Patients diagnosed with GVHD who have not responded satisfactorily to, or are intolerant of, treatment with standard agents will be considered for entry. Patients will be allowed to continue on their other immunosuppressive drugs at stable doses during the trial. The research is being conducted at up to 20 clinical research sites in the US.
NCT00048776
Juvenile secondary Raynaud's (ray-knows) Phenomenon is a disorder of the blood vessels in the fingers and sometimes can affect the toes, nose, or ears. Children with secondary Raynaud's Phenomenon have an underlying condition such as systemic lupus, scleroderma, or mixed connective tissue disease. When children with secondary Raynaud's are exposed to chilly or cold conditions from weather, cold temperatures, or even holding cold items from the refrigerator, their fingers may become cold, numb, hurt, and/or turn purple or white. The investigational drug, Pletal(cilostazol), which has been approved for other conditions, inhibits the ability of one type of blood cell, platelets, to form blood clots, and also widens narrowed blood vessels. It has been used in a variety of other conditions in which blood flow is decreased. This study will test the safety and effectiveness Pletal(cilostazol) to lessen the severity of the symptoms and decrease the number of secondary Raynaud's episodes in juvenile patients.
NCT00048763
