NCT00000126
To follow all patients enrolled in the original Ischemic Optic Neuropathy Decompression Trial (IONDT) to determine (1) the incidence of non-arteritic ischemic optic neuropathy (NAION) in the second eye, (2) changes in visual acuity over time in both the study and second eye, and (3) other aspects of the natural history of NAION.
NCT00113412
One measurement of an HIV infected person's risk of progressing to AIDS is the number of viral particles of HIV in their blood (called a "viral load"). In a previous phase I/II study, SP01A was observed to significantly lower the amount of HIV in blood, improve quality of life (how well subject's felt), have a favorable safety profile (minimal side effects), and be well tolerated. Moreover, in in vitro testing SP01A: (1) demonstrated comparable or greater efficacy than currently approved anti-HIV drugs in preventing HIV virus replication; (2) was observed to have minimal toxic effect on human cells; and (3) demonstrated significant efficacy in preventing virus replication of HIV virus strains that resist currently approved anti-HIV treatments. Based on these results, SP01A demonstrates promise as a new and novel anti-HIV treatment. The goal of this study is to further look at the dose response, efficacy, and safety of SP01A as monotherapy, given as a capsule to be swallowed, in the treatment of HIV-infected subjects. The investigators want to see if SP01A will lower the amount of HIV in blood. Subjects will be assigned by chance to 1 of 4 groups. Neither the subject nor the study doctor or nurse will know which dose of the study drug the subject is taking or if the subject is receiving the placebo (a capsule that looks like the study drug but does not contain any active ingredient). At the end of the 10-day study, the subject will be offered testing of their virus for resistance to approved drugs (genotype) and transferred to their physician for continued treatment with FDA-approved antiretroviral therapies. If the subject experiences a side effect, which continues past the end of the study, they will be further monitored until the side effect goes away.

NCT00215215

NCT00073502

NCT00094003
This study is to investigate the safety of NS-9 and to see how well it is tolerated in patients with cancer that has metastasized (spread) to the liver from another primary tumor. NS-9 is a drug developed to go to the liver to cause cell death specifically in tumor cells. This study is also set up to determine the best dose to use.

Subjects will receive oral lenalidomide days 1-21 and weekly gemcitabine days 1, 8, \& 15 in 28 day cycles until documented disease progression occurs.
NCT00023348

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.
NCT00000363
Acute otitis media is one of the most common diseases of childhood and is one of the major causes of hearing loss in children. Despite the availability of effective antibiotic therapy for otitis media, treatment failures, persistent effusions, and recurrences are common. This Phase III outpatient study aims to test whether adjuvant therapy (an antihistamine or a corticosteroid), in addition to antibiotic therapy, improves the acute and long-term outcomes of patients with acute otitis media. This study is targeted to recruiting 200 infants (age less than one year); patient (and parent) participation is estimated to continue for one year after enrollment.
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.
NCT00033150
Brief Summary: Nearly 7% of elementary school children present with difficulties learning and using language. Unfortunately, language impairments are often long lasting and may have serious social, academic, and vocational ramifications. More than 1 million children receive language intervention in the public schools each year, and many more are seen in hospitals and other clinical settings. This randomized clinical trial compares the language outcomes of Fast ForWord to two other interventions (computer assisted language intervention without acoustically modified speech and individual language intervention) and to the outcomes of an academic enrichment (control) condition. Each year for 3 years, children will be randomly assigned to each of the four conditions at three regional sites (Austin, Texas, Dallas, Texas, and Lawrence, Kansas). The treatments will be administered in special summer programs. The primary research question is which intervention results in the most improvement in the composite language score from the Oral and Written Language Scales. Secondary questions include which intervention results in the greatest gains in conversational language,which intervention results in the greatest gains 3 and 6 months after training, which intervention results in the greatest improvement in auditory perception, and which intervention is the most cost effective. The results of the study will have theoretical and practical value. Theoretically, the study tests the temporal processing hypothesis of language impairment. Practically, the study will describe and compare the language, communication, auditory processing and academic outcomes of different language interventions. The study will help clinicians and administrators choose the most effective and least expensive treatment for the children they serve.
