Hotspots, Households and Hospitals: Enhanced Drug-resistant Tuberculosis Case Finding in Namibia...

TuberculosisMultidrug-Resistant

Poor case management, pharmacokinetic variability and on-going transmission have fostered the drug-resistant tuberculosis (DR-TB) epidemic leading to a global estimated number of >500,000 new multidrug resistant (MDR) TB cases per year, of which roughly 10% are extensively drug resistant (XDR). Namibia is a high TB burden country with an incidence rate of 446/100,000 in 2016; about 11,000 new cases per year. 3.9% of new cases and 8.7% of previously treated cases have MDR-TB. Whole genome sequencing (WGS) has recently been applied to interrogate the complete genetic code of Mycobacterium tuberculosis (Mtb) strains. WGS can be used to infer relationships between identified strains as well as determine genomic variations involved in resistance development. The specific aims of the H3TB study are to: (i) characterise the DR-TB epidemic, in terms of clinical, epidemiological, geospatial, social network and laboratory data, to identify transmission hotspots in three regions of Namibia, (ii) evaluate the feasibility of targeted case finding intervention strategies to improve DR-TB control in highly affected populations and (iii) develop a transmission model to investigate the potential impact of the case finding intervention strategies on DR-TB incidence in Namibia. A prospective surveillance study started in January 2020, which includes all DR-TB cases in Namibia, and which will nest H3TB. Data collection tools and other study implementation tools have been designed and implemented. The study team is working in close collaboration with the National Institute of Pathology, where all DR-TB cases from the country are registered, to ensure all possible cases are captured. This is important for the identification of transmission hotspots. After HREC and MOHSS approval, individuals with GeneXpert® MTB/RIF rifampicin-resistant samples and a positive Mtb culture from three regions in Namibia will be included in a transmission hotspot identification study. Preliminary data have shown that DR-TB clusters exist in these regions. Clinical, epidemiological, geospatial, social network and laboratory data (GeneXpert® MTB/RIF, culture, drug sensitivity tests) will be collected. WGS capacity has been established at the UNAM research laboratory, where WGS will be performed on the samples of H3TB participants; results will be validated at the Research Center Borstel in Germany. These study results in conjunction with a systematic review and meta-analysis will inform the design of case finding interventions which will be evaluated through a mixed-methods feasibility study conducted at high transmission areas (hotspots, households and hospitals). Data from these studies and the TB programme will be used to develop the model which will include a health economics component. The study will strengthen DR-TB diagnosis, surveillance and control, inform DR-TB case finding policy in Namibia and regionally, inform resource allocation by identifying high transmission areas and create preliminary data to design a large scale DR-TB case finding intervention.

Training Protocol on the Natural History of Tuberculosis

Mycobacterium InfectionsTuberculosis4 more

Background: - Tuberculosis (TB) is an infectious disease that affects numerous people worldwide. Researchers are interested in actively recruiting individuals with TB for research and treatment studies. Objectives: - To collect blood and other samples to study the natural history of tuberculosis. Eligibility: - Individuals 2 years of age and older who have either active or latent tuberculosis. Design: Latent TB patients: Participants will have a single study visit with a physical examination and medical history, and will provide blood samples for testing. Active TB patients: Participants will have an initial visit with a physical examination and medical history, and will provide blood samples for testing. Participants will also provide sputum samples if required, and may have an optional skin punch biopsy to collect a sample of skin tissue for study. Treatment for active TB will be provided as part of this protocol. Active TB participants may be asked to return for study visits every 1-2 months while receiving treatment....

An Adaptive Randomized Controlled Trial

Multi Drug Resistant TuberculosisHIV Infections

This is a prospective, adaptive, randomized controlled trial comparing the effectiveness of 4 intervention arms on a combined endpoint in adults with confirmed MDR-TB HIV initiating Bedaquiline-containing MDR-TB treatment regimens and on ART (integrase strand transfer inhibitor (INSTI)-based fixed dose combination therapy) in KwaZulu-Natal, South Africa. Interventions arms include: enhanced standard of care; psychosocial support; mHealth using cellular-enabled electronic dose monitoring; combined mHealth psychosocial support. Level of support will be adjusted using a differentiated service delivery (DSD)- informed assessment of treatment support needs.

Safety of RUTI® Vaccination in MDR-TB Patients

TuberculosisMultidrug Resistant

Prospective, randomized, double-blind, multicentre, placebo-controlled clinical phase IIa trial to evaluate safety and immunogenicity of RUTI® vaccine in Multidrug-resistant Tuberculosis (MDR-TB) patients favourably responding to standard MDR-TB treatment. Time point of vaccination starts at 16 weeks upon start of standard MDR-TB treatment (cohort A), and if clinically safe as evaluated by an independent panel of experts (DSMB), another cohort of patients will be vaccinated at 2 weeks upon start of standard MDR-TB treatment (cohort B), All the patients will be followed up 8 weeks after vaccination.

FS-1 Drug for Treatment of Multiple Drug-resistant Tuberculosis

TuberculosisMDR

Drug-resistant tuberculosis is becoming a major problem for the whole humanity, and development of new Anti-TB drugs is of great importance. Since Kazakhstan is a country with the high burden of tuberculosis, the Government of the Republic of Kazakhstan has founded initiative on the development of new Anti-TB drug to treat drug-resistant forms of this infectious disease. JSC "Scientific Center for Anti-infectious Drugs" has developed original drug FS-1 for the treatment of multidrug resistant tuberculosis (MDR-TB).

A Trial to Evaluate Safety, Tolerability, and Efficacy of Orally Administered OPC-67683

TuberculosisMultidrug-Resistant

A phase 2, multicenter, uncontrolled, open-label trial in participants with Multi-drug Resistant Tuberculosis (MDR-TB). Only participants who completed Trial 242-07-204 (NCT00685360) were eligible. The trial was performed globally at 14 sites qualified to treat MDR-TB. All 434 participants who completed Trial 242-07-204 were eligible for this trial if there was still potential clinical benefit to them and all inclusion criteria and no exclusion criteria were met.
