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.
NCT00050843
The primary objective of the study is to determine the efficacy of thalidomide for the treatment of anemia in patients with myelodysplastic syndromes (MDS).
NCT00046072
Sepsis is a serious condition where there is inflammation and damage to body tissue, usually caused by an infection. This infection can lead to decreased function of vital body organs and in some cases may lead to permanent health problems or death. Much of the injury is due to endotoxin, a harmful substance produced by certain types of bacteria. An endotoxin antagonist is designed to block the effects of endotoxin. This study is designed to study the safety and efficacy when treating patients with severe sepsis.
NCT00078065
This trial is a phase II, randomized study of patients with multiple myeloma. All patients will receive Xcellerated T Cells, with or without prior fludarabine therapy. 15 patients in each study arm will be followed for 6 months.
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.
NCT00134225
The investigators hypothesize that non able-bodied participants with reported acute, sub-acute, or chronic symptoms of neck or back pain of a musculoskeletal origin will have magnetic resonance imaging (MRI), X-ray and blood parameters that do not demonstrate a statistical difference between "normal" (able-bodied) volunteers. Muscle pattern recognition (MPR) testing will show statistically different results between these groups. This statistically significant finding in MPR results will enhance a clinician's determination of clinical normality or abnormality. If this hypothesis is demonstrated, the MPR modality will be the first quantitative tool developed for assisting in the diagnosis of the presence or absence of a musculoskeletal dysfunction in a patient population. The availability of such an evaluation tool to a healthcare provider for patients with soft tissue, non-surgical neck or back complaints will substantially improve the accuracy of diagnosis and case management decisions.
NCT00002322
To determine the tolerance and antiviral response of two different doses of atevirdine mesylate (U-87201E) in symptomatic HIV-positive patients with CD4 counts of 50-350 cells/mm3, who also take zidovudine (AZT).
NCT00087542
The primary objective is to demonstrate that the investigational new drug, ACP-103, is well tolerated by, and will not worsen parkinsonism in, patients with Parkinson's disease and psychosis. The secondary objectives are to determine whether ACP-103 will ameliorate psychosis in patients with Parkinson's disease and whether ACP-103 is safe in Parkinson's disease patients taking multiple anti-parkinsonian medications.
NCT00121147
The purpose of this study is to compare the additive effect on eye pressure of Azopt and Alphagan P to Travatan.
NCT00023348
Primary Objectives: 1\) To determine the proportion of patients with HIV-related tuberculosis who have abnormal pharmacokinetic parameters for isoniazid and rifabutin. Secondary Objectives: 1. To determine risk factors for abnormal pharmacokinetic parameters for isoniazid and rifabutin. 2. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the occurrence of toxicity attributed to antituberculous therapy. 3. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the efficacy of TB therapy. 4. To define and correlate phenotypic INH acetylator status with the results of genotypic acetylator data obtained in the parent trial.
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.
NCT00088192
To provide Pegaptanib sodium injection to patients with subfoveal choroidal neovascularization (CNV) secondary to AMD, who are unable to participate in any of the Sponsor's other clinical studies with this drug for AMD, until such time as the patient's lesion is considered to have resolved or stabilized in the opinion of the treating ophthalmologist, or product becomes commercially available.
NCT00100724
The purpose of this study is to assess the safety and immunogenicity of rPA102 vaccine given intramuscularly at 0 and 4 weeks over 2 dose ranges and 4 adjuvant levels.
NCT00073502
Multi-center, open-label, non-randomized Phase II study to evaluate the efficacy and safety of OSI-7904L in gastric and GEJ cancers. Those patients who do not derive clinical benefit after two cycles may be switched to a commonly used combination regimen.
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
Juvenile primary Raynaud's (ray-knows) Phenomenon is a disorder of the blood vessels in the fingers and sometimes can affect the toes, nose, or ears. When children with primary Raynaud's Phenomenon 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. Children with primary Raynaud's Phenomenon have no underlying systemic disease. The cause for their symptoms is unknown. 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 primary Raynaud's episodes in juvenile patients.
NCT00002257
