Filter by:Clofazimine (CFZ) is a promising drug for the treatment of NTM diseases. CFZ is highly active in vitro against M. abscessus and M. avium, the most common NTM pathogens, and shows synergy with macrolides and amikacin. The results from limited clinical studies with CFZ-based treatment regimens are promising. CFZ is currently considered an alternative drug for patients with M. avium complex infections, who are intolerant of first-line drugs. CFZ is a first-line oral drug for treatment of M. abscessus infections. CFZ might prove to be a cornerstone in NTM treatment, but its optimal dosage is not known. The current dose for adults is 100 mg oncedaily. However, due to the complex pharmacokinetics (PK) of CFZ - it is highly protein bound, extremely lipophilic and accumulates in fatty tissues resulting in a long elimination half-life of ~30 days - it takes several months before steady state, and presumably effective, concentrations are achieved. With the use of a loading dose regimen concentrations similar to those at steady state could be reached faster, possibly leading to improved early treatment efficacy. The overarching aim of this study is to contribute to dose optimization of CFZ in the treatment of NTM diseases. It will be an explorative, single-center, one-arm, open label, pharmacokinetic study. A number of 10 patients with pulmonary or extrapulmonary NTM disease will be included. Patients will receive a loading dose regimen of 300 mg once daily for 4 weeks and will then continue with a standard dose of 100 mg once daily until a total 4 months of treatment with CFZ. The primary objective of this study is to describe the PK of CFZ, after 4 weeks of treatment with a loading dose regimen of 300 mg once daily, in adult patients with pulmonary or extrapulmonary NTM disease
Based on the collected antibiotic concentration data and individual patient's clinical information, a pharmacokinetic analysis report that can be applied for dose adjustment of the individual patient is provided. The pharmacokinetic/pharmacodynamic index using the minimum inhibition concentration (MIC) of the antibiotic obtained from the patient's clinical isolate is also explored. Utilizing these, we intend to establish a population pharmacokinetic model of antibiotics prescribed in treating Tuberculosis and Nontuberculous mycobacteria (NTM). The developed population pharmacokinetic model can be applied for therapeutic drug monitoring (TDM) based on dose adjustment through the obtained pharmacokinetic parameters.
The SALINE trial will investigate the effect of Hypertonic Saline inhalation plus best supportive care on burden of symptoms, clearance of mycobacteria and functional capacities in participants with Mycobacterium avium complex lung disease and compare the effect to treatment with best supportive care alone.
- To evaluate the change in M. abscessus cfu/g in induced sputum samples from baseline to the end of treatment with RESP301 in patients with cystic fibrosis who have treatment-naïve or treatment-refractory M. abscessus-pulmonary disease - To assess the safety and tolerability of RESP301 during treatment (28 days) and follow up (84 days) in patients with cystic fibrosis who have treatment naïve or treatment refractory M. abscessus-pulmonary disease
Non-tuberculous mycobacteria (NTM) are increasingly common and have a poor prognosis: 5-year mortality can reach 40 to 50%, depending on the type of mycobacteria and the immune system of the host involved. Cancer patients are at higher risk of infectious morbidity and mortality, which may be due to disease-related immune dysfunction, immunosuppressive effects of chemotherapy, or long-term placement of a vascular catheter. However, data on the treatment of NTM species that cause infections and the disease characteristics of these pathogens in cancer patients are limited despite the growing cancer population worldwide. Recently, M. avium infections have been described in patients suffering from cancers (hematological or not), in particular in patients receiving checkpoint inhibitors. Although the proportion of M. avium pneumonia in retrospective series is low (0.8-2%), it has been shown that this population is younger, suffers less from sub-pulmonary pathology. (indicating immunosuppression in these patients) but are therefore treated less than non-cancerous subjects. This retrospective study in CHU Amiens is searching on the number of side effects of NTM treatment in two groups (cancerous and no cancerous) to assess the cause of the decrease of NTM treatment in cancerous patients.
The purpose of this study is to evaluate the efficacy, safety and tolerability of oral omadacycline as compared to placebo in the treatment of adults with Nontuberculous Mycobacterial (NTM) pulmonary disease caused by Mycobacterium abscessus complex (MABc)
The MAC-HS study is a testing whether hypertonic saline helps improve symptoms and clearance of mycobacteria in patients with M. avium complex lung infections.
This is pilot study of the immunologic effects of intradermal Bacille Calmette-Guerin (BCG) vaccination of adults with cystic fibrosis (CF), non-CF bronchiectasis (NCFB), and healthy volunteers.
This study is a Phase 1, single-center, open-label study to investigate the absorption, metabolism, and excretion of BTZ-043 after a single oral administration of 500 mg BTZ-043 containing 3.7 MBq of [14C]BTZ-043 in 4 healthy adult male subjects
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.
