Researchers at the University of Cape Town have compared the T-cell responses of individuals who were infected with Mycobacterium tuberculosis but were able to control the infection to those who developed active disease. The researchers wrote that the shared antigens in controllers “can be considered as high-priority targets for future vaccine development.” Their results were published online in Nature Medicine on Jan. 5, 2023. In their experiments, the team first sequenced the CDR3β region of the T-cell repertoire in a total of 166 individuals with M. tuberculosis infection who progressed to either TB or controlled infection.
Given all the advances that have been made over the past decade, the U.S. FDA decided to issue a new draft guidance on developing antibacterial drugs to treat pulmonary tuberculosis (TB) rather than finalize the draft it issued in 2013. In releasing the new draft, the agency cited advancements made in nonclinical models, streamlined clinical development programs and growing interest in treatment-shortening combination regimens.
George Washington University has described N-ACYL fosmidomycin prodrug analogues acting as 1-deoxy-D-xylulose-5-phosphate reductoisomerase (Dxr; IspC) (Mycobacterium tuberculosis) and Dxr (Plasmodium falciparum) inhibitors reported to be useful for the treatment of malaria and tuberculosis.
Researchers at St. Louis University, Washington University in St. Louis, and Fimbrion Therapeutics Inc. have identified ubiquinol-cytochrome C reductase cytochrome b subunit (qcrB) (Mycobacterium tuberculosis) inhibitors reported to be useful for the treatment of tuberculosis.
At the Saturday, Oct. 22 session, ‘Basic Science: Correlates of protection, immune response and the host-microbe interaction,’ of the IDWeek 2022 infectious disease conference, moderator Luiz Bermudez, professor at Oregon State University, introduced the latest advances to prevent infections with Treponema pallidum during neurosyphilis (NS), Staphylococcus aureus and osteomyelitis, and Mycobacterium tuberculosis during influenza.

GSK plc scientists seeking compounds with the potential to treat resistant tuberculosis infection identified a series of tetrazole agents using phenotypic screening against Mycobacterium tuberculosis.
Scientists have discovered a new antibiotic called evybactin that is able to selectively target Mycobacterium tuberculosis, the bacteria that causes tuberculosis (TB) lung infections. As described in NatureChemicalBiology on Aug. 22, 2022. the work is still at an early stage and requires further validation. But, if successful in clinical trials, evybactin could form part of a new group of specific antibiotics designed to target TB.
The Project to Accelerate New Treatments for Tuberculosis is progressing two investigational tuberculosis combination treatment regimens into phase II trials under a joint development agreement.
