ANTI-TB
Antibiotics nanocarrier for therapeutic inhalation against tuberculosis

 

Tuberculosis is worldwide the most relevant bacterial infectious disease in humans with around 10 million new cases in 2017. Its agent, Mycobacterium tuberculosis, tops the WHO list of the deadliest infectious diseases, which killed 1,6 million people in 2017. The pathogen hides in host scavenger cells encapsulated in inflammatory foci, the granulomas, in the infected tissue, primarily in the lung. Antibiotic treatment is required to be given for at least 6 months but is often accompanied by significant adverse effects, which can lead to premature termination of the therapy. Thereby, the occurrence of antibiotic-resistant strains is promoted further hampering successful therapy.

The "ANTI-TB – antibiotics nanocarrier for therapeutic inhalation against tuberculosis" consortium explores a nanomedical approach to better target the infectious hideout of tuberculosis agent thereby enhancing local but lowering systemic antibiotic levels. We hope this approach will help to limit future development of antibiotic resistance. Our nanocarriers are combined with novel anti-tuberculosis drugs to form antibiotic-nanocarriers. For targeting, nanocarrier surfaces are modified to be specifically recognized by infected cells for optimal transport to the pathogen’s intracellular niche. Most effective antibiotic-nanocarriers will be further developed for inhalation therapy to make application easier for the patients.

Our strategy aims to increase local drug concentration in infectious sites within lungs to shorten duration of therapy, reduce adverse effects and consequently, improve patient compliance.

Reading tip: Nanoparticles - Use in medicine

Nanoparticles can provide valuable services in many areas of medicine: whether in diagnostics, e.g. in the early detection of various types of cancer, or in therapy, through the development of so-called nanocarriers, which can transport drugs specifically to the sources of disease. Helmholtz Center Munich, in cooperation with the German Centre for Lung Research (DZL), has now published an overview article on the current state of research and the future of medical nanoparticles on its Lung Information Service portal: www.lungeninformationsdienst.de

With small particles against tuberculosis: BMBF supports nanomedical research project to fight against therapy-resistant pathogens

Over the next three years, the ANTI-TB research consortium will receive 2.8 million Euros of funding from the German Federal Ministry of Education and Research (BMBF). The aim of the project is use nanocarriers to improve therapies of antibiotic resistant tuberculosis. The project partners include the Borstel Research Centre, the Leibniz Institute for Medicine and Biosciences (FZB), the Karlsruhe Institute of Technology (KIT), the Fraunhofer Institute for Toxicology and Experimental Medicine Hanover (ITEM), the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), the Martin Luther University Halle-Wittenberg (MLU-HW) as well as the biopharmaceutical company Rodos Biotarget GmbH (RBT). The Borstel Research Centre is the coordinator of this innovative research network. Rodos Biotarget is responsible for the commercialization of the research and development results.

With 2.2 billion infected people worldwide, tuberculosis is the most important bacterial infection in humans. According to the WHO, 10.4 million people worldwide contracted tuberculosis in 2015 alone and 1.8 million died as a result of the infection. The fight against tuberculosis is hampered by the increased occurrence of therapy-resistant strains of the pathogenic agent, which is further accelerated by therapy drop outs. "Patients with multi-drug resistant or extensively drug resistant tuberculosis must take medication for up to 24 months - with sometimes severe adverse effects. With our new therapeutic approach, we aim to target specifically the infectious foci in order to enhance local drug concentrations, shorten duration of therapy and minimize systemic adverse effects. Thereby, we hope to increase the willingness of patients to stick to the therapy to the very end and reduce drop-out rates to 50%" said Prof. Ulrich E. Schaible, Director of the Program Area Infections at the Borstel Research Centre and coordinator of ANTI-TB.

In order to improve tuberculosis therapy and limit further development of resistant strains of the tuberculosis agent, ANTI-TB follows a nanomedical approach by constructing nanocarriers of only a few nanometers in diameter and a modified surface carrying address molecules for infected cells. These nanocarriers are loaded with novel antibiotics should specifically target infectious sites in the lung. "The aim of our joint project is to develop antibiotic nanocarriers ready for clinical testing. The most effective variants will be designed for an aerosol or powder-based inhalation therapy," explains Professor Schaible. "Through inhalation, we hope to increase antibiotic concentrations in the infected lungs to minimize length of therapy and to reduce the burden of adverse effects for the patients.”

In the field of medical imaging and tumor therapy, nanomaterials are intensively studied, and some are already in clinical use. Nanocarriers as transport systems for antibiotics have so far been less developed. ANTI-TB starts exactly at this point. The interdisciplinary cooperation between chemists, pharmacists and microbiologists within this consortium will lead to the development of a new therapeutic concept that could also become applicable to other diseases in the future. While KIT and Rodos Biotarget are designing novel nanocarriers, ITEM and HIPS are developing inhalable formulations, the Pharmaceutical Institute of the University of Halle is carrying out toxicological studies. The FZB, with its expertise in tuberculosis research, uses appropriate infection models to investigate the efficacy of the new therapeutics against the tuberculosis agent. As an enterprise, Rodos Biotarget will finally generate the most effective formulations according to international quality standards ready to be marketed.

Against the background of increasing resistance of bacterial pathogens to antibiotics, the Federal Ministry of Education and Research (BMBF) established the program "Promotion of Diagnostics and Novel Therapies for the Treatment of Bacterial Infections" in 2016. Thereby, the BMBF hopes to advance the development of new diagnostics for the targeted use of antibiotics as well as the development of novel therapies for the treatment of bacterial infections in human medicine. The ANTI-TB research project was approved by the BMBF at the end of September and will start on October 1st, 2017.
