Filter by:Tuberculosis (TB) remains the most important infectious disease in the world. Preventive treatment plays an important role in successful control of TB. The investigators' previous study showed a 3-month weekly rifapentine and isoniazid regimen had a high protective efficacy but an unsatisfactory completion rate. Therefore, the investigators suppose that a one-month (12-dose) regimen of rifapentine and isoniazid (1RPT/INH) to be equivalent to a 3-month weekly rifapentine and isoniazid regimen with similar efficacy and higher completion rate. Relevant study is lacking in China where the TB burden is high with the incidence rate of 70/100, 000. Silicosis is a risk factor of Mycobacterium tuberculosis infection. This is an open-label, non-randomized clinical trial to evaluate the efficacy and safety of the 1RPT/INH to prevent tuberculosis (TB) compared with those who do not receive preventive treatment among silicotic patients.
Tuberculous meningitis (TBM) is the most serious form of Mycobacterium tuberculosis infection, causing mortality and disability in more than half of the patients. Current standard treatment for TBM is based on those developed to treat pulmonary tuberculosis, which does not take into account the differential ability of anti-tuberculosis drugs to penetrate the brain. With both good central nervous system penetrance and anti-tuberculosis efficacy that have been demonstrated in drug-resistant tuberculosis, linezolid may be a promising antimicrobial in TBM treatment. The purpose of this study is to evaluate the effectiveness of linezolid in the treatment of TBM.
This is a Phase I, open-label, single dose, sequential group study to compare the safety and pharmacokinetics of pretomanid in the following groups of subjects: 1) subjects with severe renal impairment including those with End Stage Renal Disease (ESRD) not needing dialysis, and subjects with mild or moderate renal impairment, designated as Groups 2, 3, and 4, respectively; and 2) subjects with normal renal function matched to the above renal impairment groups, designated as Groups 1A, 1B, and 1C, respectively. The study will be conducted following a reduced Pharmacokinetic (PK) study design in Part A and Part B. Part A will enroll subjects from Group 1A (i.e., 6 healthy matched controls) and Group 2 (i.e., 6 subjects with severe renal impairment and ESRD, not on dialysis). A decision will be made after the PK of pretomanid and safety of subjects enrolled in Part A have been reviewed. If Part A demonstrated different pretomanid exposures at least a 50-100% increase in Area under the Curve (AUC) in Group 2 (severe renal impairments and ESRD, not on dialysis) relative to the exposures in Group 1A (matched subjects with normal renal function), then the reduced PK study will extend to the full PK study to enroll subjects into Part B (i.e., to investigate mild, and moderate renal impairment) and all enrollment will be initiated concurrently in Part B groups (1B, 1C, 3 and 4). If no difference in PK and safety is observed in Part A, then no further study (Part B) is recommended The approximate patient involvement will be 3 months. The primary objective is to evaluate the PK profiles of pretomanid in plasma and urine after a single oral dose of 200 mg in subjects with renal impairment compared to matched healthy controls.
endTB-Q Clinical Trial is a Phase III, randomized, controlled, open-label, non-inferiority, multi-country trial evaluating the efficacy and safety of two new, all-oral, shortened regimens for multidrug-resistant tuberculosis (MDR-TB) with fluoroquinolone resistance.
The purpose of this study is to evaluate the safety, pharmacokinetics, and effects of imatinib on myelopoiesis in adults when given with and without isoniazid and rifabutin. The results of this trial will determine the imatinib dose to be studied in a subsequent Phase IIB treatment trial of imatinib as an adjunctive therapy with an antimicrobial regimen (rifabutin, pyrazinamide (PZA), isoniazid (INH) and ethambutol) for drug-sensitive TB.
Drug therapy for persons living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) co-infected with latent tuberculosis infection (LTBI) is complex. Anti-tuberculosis drugs used to treat LTBI often induce drug metabolizing enzymes that share the same metabolic pathway as antiretroviral drugs used for those living with HIV/AIDS. This study evaluates the drug-drug interaction (DDI) potential of an antiretroviral drug when co-administered with a common anti-tuberculosis regimen of drugs.
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of pravastatin adjunctive therapy when combined with the standard tuberculosis (TB) treatment regimen in adults with TB.
Isoniazid preventive therapy (IPT) reduces the risk of tuberculosis in 60%. Young children are at higher risk of developing severe forms of TB, though this can be prevented with a full course of IPT. Preliminary data indicate that 60% of eligible children start IPT, and 30% complete it. Furthermore, children can be exposed to more than one case of TB in the household. Adults exposed to TB in the household setting are not necessarily aware of their risk. Uncertainties in the decisions of staff to prescribe IPT and limited health literacy among caretakers and families contribute to this. The investigators will determine the efficacy of an intervention package to increase IPT adherence and completion among children < 5 years old exposed to TB in the household. The investigators will assess the efficacy of the intervention by 1) measuring IPT completion at 6 months after treatment initiation and by 2) determining adherence to IPT by measuring isoniazid in urine at weeks 2, 8 and 24 in a random cluster sample of 10 health facilities and 20 control facilities with 10 children included in each facility (100 in intervention and 200 in control). The investigators will measure fidelity and reach, and acceptability among caretakers and health staff. The intervention package will consist of: 1) educational booklet for caretakers explaining why IPT needs to be given 2) a children's storybook, with weekly installments, over the 6-month course of IPT as a non-monetary incentive and 3) short messages services (SMS) reminders delivered to the caretaker for the weekly pick-up In September 2020, the protocol was updated to adapt to the COVID19 situation in Lima. One of the secondary outcome (isoniazid concentration in urine) was cancelled and the full intervention (educational booklet, weekly children storybook and weekly SMS) is now delivered through WhatsApp.
This is a double-blind, randomized (in 3:1 ratio -vaccine : placebo) study to assess the safety, reactogenicity and immunogenicity in healthy, BCG vaccinated adults.
Previous studies have shown that a small incentive can have a large impact on health behaviors like vaccinating children. New Incentives, an international non-governmental organization (NGO), aims to boost demand for immunization by offering cash incentives to caregivers who have their child vaccinated at a program clinic. In collaboration with New Incentives, IDinsight is conducting a study to see whether this approach will increase immunization in North West Nigeria. This study aims to investigate whether giving cash to caregivers in North West Nigeria who bring their infants to receive vaccination against common infections (tuberculosis, diphtheria, tetanus, pertussis, hepatitis B virus (HBV) infection, Haemophilus influenzae Type B (Hib), pneumococcal bacteria, measles, rotavirus, polio, yellow fever) increases the proportion of children who are immunized. The study's main hypothesis is that New Incentives' program will increase the percentage of children immunized with BCG, any PENTA, or Measles 1 by an average increase of at least 7-percentage points across all program clinics that share a similar profile to the clinics New Incentives will operate in at scale. The study is taking place in Jigawa, Katsina, and Zamfara States between August 2017 and January 2020.
