Filter by:PredictEndTB signature is a non-inferiority, prospective, parallel-group open-label randomized controlled trial evaluating the efficacy of individualised antituberculous treatment durations that utilize the transcriptomic signature-based model compared to the standardised twenty months treatment in a cohort of multidrug-resistant tuberculosis patients.
To evaluate the pharmacokinetics (PK) of SPR719, the active moiety, generated from the orally (po) administered SPR720 prodrug in a patient population with nontuberculous mycobacteria pulmonary disease (NTM-PD)
A prospective, single-center, single-blinded study involving patients with refractory nontuberculous mycobacteria lung disease to ascertain pharmacokinetics, safety, efficacy, and tolerability of two dose levels of parenteral administration of recombinant Interleukin-7 (IL-7) (CYT107).
A study to evaluate the efficacy of inhaled molgramostim administered open-label to adult cystic fibrosis (CF) subjects with chronic pulmonary nontuberculous mycobacterial (NTM) infection, with or without ongoing antimycobacterial guideline based combination therapy.
Although Cystic Fibrosis is a complex genetic disease affecting many organs, lung disease is the primary cause of mortality. The objective of this study is to determine the safety and tolerability of SNSP113 in healthy subjects and subjects with stable cystic fibrosis.
Background: Tuberculosis (TB) is a severe disease and a major cause of death in many people worldwide. It is caused by a bacteria that enters through the lungs and can spread elsewhere in the body. People with latent TB have the bacteria that lie dormant but can become active and cause disease. These people are offered treatment to prevent development of active TB. Worldwide, a lot of people with LTBI also have a parasitic worm called a helminth that can stay in the gut or the blood. These parasites can affect the immune system and cause diseases like TB to become worse. Researchers want to see how helminth infection makes it harder for people to fight TB infection. Objectives: - To study how the immune system of people with latent tuberculosis infection (LTBI) acts to prevent development of active TB. Also, to study how helminth infection might affect this immune response. Eligibility: - Adults age 18 70 with LTBI as defined by an approved blood test called QuantiFERON TB Gold. - No evidence of infections like Hepatitis or HIV - Pregnant subjects and subjects taking medications that suppress the immune system are not eligible. - Have not received prior treatment for LTBI. Participants might be still eligible if prior treatment for active TB has been received Design: Screening phase: - Participants will be screened with medical history, physical exam, and blood tests for other infections/conditions which might affect the immune system. They will have testing for active TB i.e. blood testing as well as testing of their spit, scans and X-rays. Baseline phase: - Only eligible participants will be entered into the study. - Participants will have interviews, medical history, and physical exam. - Blood will be drawn from an arm vein for testing. - Participants will collect stool samples at home for 3 days in a row to test for helminth infection.. - Participants may have apheresis. Blood cells are removed by needle. They pass through a separator machine which returns everything but the cells back to the participant. - Participants may have procedures at the start and end of the study that let researchers look into the lungs and collect cells. Study phase, about 2 years: - All participants will be offered treatment for LTBI which lasts 6-9 months. - Participants being treated for LTBI will have about 11 study visits. They will visit monthly for 9 months while on treatment, then 6 and 12 months after treatment. - Participants not eligible/refusing treatment for LTBI will be made aware of active TB, then have 3 other visits, about 6, 12, and 24 months after the baseline visit. - Participants who have helminth infection will receive appropriate treatment. - All participants will have blood drawn at each visit.
Little is known about the disease caused by the nontuberculous or environmental mycobacteria (NTM) and only limited data are available showing treatment outcome. This project will study the patients with nontuberculous mycobacterial (NTM) diseases in the University of Illinois Hospital & Health Sciences System (UIMC). The aim of study is finding treatment outcome and risk factors that are associated with treatment failure in NTM patients. This is a retrospective, observational study for collecting data on patients with NTM in UIMC. The study initially involves populating the study of NTM patients seen at UIMC during the study period. This will add our knowledge about current treatment outcome of patients with NTM diseases and will be of interest to physicians, and public health authorities.
Background: -Tuberculosis (TB) is an infection of the lungs caused by bacteria. In Mali, TB is diagnosed with a test that is fast and inexpensive but not always accurate. The purpose of this study is to test a new method for diagnosing TB, called the microscopic-observation drug-susceptibility (MODS) test. The MODS test takes 7 days to show results. The test also gives information on which drugs will work best in each case. Objective: -To test a new method for diagnosing tuberculosis called the microscopic observation drug susceptibility test. Eligibility: - Participants must be 12 years of age or older. - They must have a diagnosis of TB from a sputum smear, or have symptoms of TB and an x-ray indicating that TB is present. Design: - Participants will take part in the study from 6 months to 21 months and be assigned to one of three groups, depending on what type of TB they have. - At the first visit, researchers ask questions about general health and symptoms of TB. They check vital signs, draw blood, and ask for a sputum sample. The blood is used to check for HIV infection and for the number of CD4 cells, which measures the severity of the HIV infection. - The 2-, 5-, and 6-month visits are similar to the first. Those who do not have multidrug-resistant (MDR) TB will end their participation after the 6-month visit. MDR TB is tuberculosis that has not responded to isoniazid and rifampicin. Participants with MDR TB will remain in the study for 21 months. - No treatment is provided as part of this study.
This is a phase 3 randomized, active-controlled, open-label, multicenter study that will be conducted in approximately 120 investigational sites worldwide. Subjects with either recurrent or refractory NMIBC (Ta high grade, T1 low or high grade, CIS) will be eligible for participation in this study. Refractory disease is defined as evidence of persistent high grade bladder cancer (Ta HG, T1, and/or CIS) at least 6 months from the start of a full induction course of BCG with or without maintenance/re-treatment at 3 months. Recurrent disease is defined as reappearance of disease after achieving a tumor-free status by 6 months following a full induction course of BCG with or without maintenance/re-treatment at 3 months. Subjects with recurrent disease must have recurred within 18 months following the last dose of BCG. Approximately 450 subjects will be randomized. The primary objective of this study is to evaluate the efficacy of intravesical EN3348 as compared with mitomycin C in the treatment of subjects with recurrent or refractory NMIBC. The secondary objective is to evaluate the safety of EN3348 as compared with mitomycin C in the treatment of subjects with BCG recurrent or refractory NMIBC. This study will consist of 4 phases: Screening, Induction, Maintenance and Follow-Up and will be conducted over 3 years.
The aim of the study is to evaluate the polymerase chain reaction (PCR)-Reverse Blot Hybridization Assay (REBA) for identification of nontuberculous mycobacteria (NTM) species in acid-fast bacilli (AFB) smear-positive respiratory specimens.
