Active clinical trials for "Tuberculosis"

The primary objective of the study is to evaluate the safety and tolerability of single and multiple doses of TBA-7371 in healthy subjects

Each year, 10.4 million patients are diagnosed with and 1.8 million people die from Tuberculosis (TB). Despite the availability of highly effective and accessible medications in the developing world where TB is endemic, the 6-18 month treatment regimen is often thwarted as patients fail to comply due to a lack of knowledge about the disease, desire for privacy, and/or stigma avoidance. Inappropriate medication use leading to multi-drug resistant (MDR) TB infects 5% of all TB patients, yet accounts for a significant proportion of all spending. In Kenya, the burden of TB is among the highest in the world with a prevalence rate of 558 cases per 100,000 people. There is a great need for the development of alternative protocols, which reduce the costs of treatment and burden of adherence, and more effectively motivate patients to adhere to the program. A substantial and growing literature in the social sciences demonstrates the potential of behavioral interventions for generating large increases in contributions to public goods. This 1200 participant, Randomized Controlled Trial (RCT) explores the capacity of Keheala, a feature-phone and Internet-based digital platform that uses Unstructured Supplementary Service Data (USSD) technology, to deliver behavioral interventions for improving treatment adherence, outcomes and quality of life for TB patients in Nairobi, Kenya. Keheala taps into this underutilized potential by developing a powerful, cost-effective platform for better engaging patients' sense of responsibility to their community in order to increase adherence.

The purpose of this study is to determine whether one or two four-month regimens of tuberculosis treatment are as effective as a standard six-month regimen for treatment of pulmonary tuberculosis (TB). All three regimens are administered daily, seven days each week, with direct observation of each dose by a health-care worker at least five of the seven days of each week. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide followed by four months of isoniazid and rifampin. The first short regimen is a single substitution of rifapentine for rifampin: two months of isoniazid, rifapentine, ethambutol, and pyrazinamide, followed by two months of isoniazid and rifapentine. The second short regimen is a double substitution of rifapentine for rifampin and moxifloxacin for ethambutol: two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid, rifapentine, and moxifloxacin. Target enrollment is 2500 participants. Each study participant will remain in the study for 18 months in order to include at least 12 months of evaluation of whether the participant's TB recurs.

Efavirenz (EFV) is an anti-HIV medicine that is commonly used to treat HIV infection in adults and children older than 3 years of age. This study is being conducted to look at the safety of EFV, blood levels of EFV, genetic factors that may affect blood levels of EFV, and how easy it is for infants and young children to take and tolerate EFV. This information will help recommend the best doses of EFV for children younger than 3 years of age.

LTBI Treatment is effective in prison

The purpose of this study is to evaluate the safety, tolerability and effectiveness of TMC207 in combination with an individualized background regimen (BR) of antibacterial drugs as treatment for MDR-TB

The overall aim of the project is to evaluate rifabutin (RBT) as a replacement for rifampicin (RMP), for the combined treatment of tuberculosis and HIV infection. RBT represents an alternative to RMP for HIV infected patients as its half-life is longer and the enzymatic induction effect appears to be less important on the associated antiretroviral therapy (ART) drugs. This phase II trial is to determine precisely the pharmacokinetics parameters of RBT in combination with different ART regimens in Vietnamese HIV infected patients with pulmonary tuberculosis, in order to define optimal doses that will be further tested in a larger phase III trial comparing safety, tolerability and efficacy of RBT and RMP regimens.

The primary goal of this study is to assess the effectiveness of two alcohol interventions administered singly or in combination as an integrated component of TB care provided to patients with co-occurring TB and AUDs in Tomsk, Russia. Here we propose two parts of this study: First, a pilot study to provide Naltrexone to TB patients will be conducted. If feasibility and safety are demonstrated, then we will conduct a randomized clinical trial (RCT) of the following four study arms: A Behavioral Counseling Intervention (BCI) plus treatment as usual (TAU) (i.e. standard referral to and management by an addictions specialist); Naltrexone/ Brief Behavioral Compliance Enhancement Treatment (BBCET) plus TAU BCI + Naltrexone/BBCET plus TAU TAU The RCT will be conducted only if Naltrexone use proves safe and feasible in the pilot study. However, because the pilot does not have a control group and nor is it a Phase I clinical trial, we define "safety" here as demonstration of appropriate adverse event management and adequate safety monitoring procedures, all of which will also be used in the RCT. The specific aims of the pilot are: To determine the feasibility of administering Naltrexone to patients receiving TB treatment, and To assess the safety of administering Naltrexone to patients receiving TB treatment. The investigators aim to test the following hypotheses for the pilot: co-administration of Naltrexone with TB treatment is feasible and safe in a population of TB patients with AUDs. The specific aims of the RCT are: To compare TB treatment outcomes among patients in each of the three intervention arms with the control arm of treatment as usual, and To compare the change in mean number of heavy drinking days in last month of study period compared with baseline among patients in each of the three intervention arms with the control arm of treatment as usual. The investigators aim to test the following hypotheses for the RCT: Individuals receiving one of the three interventions (Naltrexone, BCI or the combination of Naltrexone/BCI) will experience better TB outcomes and a greater change in the mean number of heavy drinking days, compared with individuals receiving treatment as usual.

This study will evaluate the effect of adding metronidazole to standard second-line therapy for tuberculosis in patients who have multi-drug resistant tuberculosis (MDR-TB) of the lungs. It will evaluate the safety and tolerability of metronidazole in combination with antituberculosis agents. Metronidazole is a drug widely used to treat bacterial and parasitic infections occurring in environments with very little oxygen such as the human colon. Nine million new cases of sputum-positive tuberculosis are diagnosed worldwide each year. Patients ages 20 and older who have symptoms of TB, who have been treated for tuberculosis but whose disease is multi-drug resistant, and who are not pregnant or breast feeding may be eligible for this study. They will be recruited in the National Masan Tuberculosis Hospital (NMTH), Masan, Republic of Korea. Patients will undergo the following tests and procedures: Collection of sputum for counting of bacteria. Drawing of blood for routine blood chemistry analysis; for measuring levels of metronidazole; TB lipid analysis; and for testing levels of T-cells, which are part of an immune response. Two targeted positron emission tomography (PET) scans, each with a computed tomography (CT) scan, and five high-resolution CT scans. Patients will receive either an 8-week course of standard second-line agents plus placebo (sugar pill) or an 8-week course of standard agents plus metronidazole. The subjects, doctors and researchers will not know which patients are taking the metronidazole until after the first 2 years of the trial. A total of 60 patients will be assigned to two cohorts of 30 patients each. After 8 weeks, all patients will return to the standard of care chemotherapy, according to normal procedures at NMTH. Side effects of metronidazole commonly reported are vaginal discharge, symptoms of Candida cervicitis and vaginitis, headache, nausea and vomiting, and dizziness. Peripheral neuropathy, an abnormal condition of the nerves, may also be a side effect. The precise incidence of neuropathy is unknown but is usually related to the duration of metronidazole use. It can almost always be reversed when the drug is discontinued. Serious side effects, though rare, may include leukopenia and thrombocytopenia (disorders in the blood), seizures and other central nervous system problems, and hepatitis. This study may or may not have a direct benefit for participants. However, it is possible that patients' drug-resistant disease may be more effectively treated as a result of metronidazole. The study may help identify new methods for measuring drug effectiveness during TB studies.
