NEW YORK and MUMBAI (January 30, 2026)—TB Alliance, a nonprofit drug developer, and Lupin Limited (Lupin), a global pharma major, today announced a global collaboration to advance the clinical development and commercialization of the investigational drug telacebec (formerly known as Q203) for the treatment of tuberculosis (TB), leprosy, and Buruli ulcer.
Under the collaboration, TB Alliance and Lupin will work together to support the continued clinical development of telacebec and prepare for its potential future commercialization, with the shared goal of improving treatment options for people affected by these neglected diseases. TB Alliance will continue to lead development activities, while Lupin will bring its global manufacturing, regulatory, and supply expertise to help ensure broad access to telacebec.
“Telacebec represents the kind of scientific innovation that has the potential to transform treatment for diseases that have long been neglected,” said Mel Spigelman, MD, President and CEO, TB Alliance. “By partnering with Lupin, we are combining deep scientific expertise with global Chemistry, Manufacturing and Controls (CMC) and access capabilities to help move this promising compound forward as quickly and responsibly as possible, with the ultimate goal of delivering better treatment options to people affected by tuberculosis, leprosy, and Buruli ulcer around the world.”
“Our collaboration with TB Alliance underscores Lupin’s dedication to addressing unmet medical needs of the patients affected by TB, leprosy, and Buruli ulcer. By leveraging our manufacturing and distribution capabilities together with TB Alliance’s leadership in drug development, we aim to deliver Telacebec to those in need and positively contribute to the global efforts against these diseases,” said Ramesh Swaminathan, Executive Director, Global CFO, and Head of API Plus SBU, Lupin.
Telacebec is a novel, first-in-class compound with potent activity against multiple mycobacterial pathogens. TB Alliance already has clinical development underway to evaluate the safety and efficacy of telacebec for Buruli ulcer, including an active Phase 2 clinical trial in Australia. In parallel, TB Alliance is advancing the TEBULA program, supported by the European & Developing Countries Clinical Trials Partnership (EDCTP), to accelerate development of telacebec for both Buruli ulcer and leprosy. These trials and this partnership underscore TB Alliance’s commitment to identifying and advancing new treatment options with the potential to help bring an end to neglected diseases. Telacebec has the potential to offer a novel therapeutic approach across multiple mycobacterial diseases, helping to simplify treatment and improve outcomes for people impacted by these neglected diseases worldwide.
TB, leprosy, and Buruli ulcer are all caused by mycobacterial infections and disproportionately affect underserved and marginalized populations. TB remains one of the world’s leading infectious disease killers, claiming more than a million lives each year. Leprosy, a chronic infectious disease, continues to cause disability and stigma for hundreds of thousands of people globally. Buruli ulcer, a neglected tropical disease, can lead to severe skin and soft tissue damage if not treated early and remains poorly served by current therapies. Together, these diseases underscore the urgent need for new, effective, and accessible treatment options.
About Telacebec
Telacebec (Q203) is a novel, first-in-class investigational compound being developed by TB Alliance for the treatment of multiple mycobacterial diseases, including tuberculosis, leprosy, and Buruli ulcer. TB Alliance in-licensed telacebec from Qurient under an exclusive license agreement, enabling the nonprofit organization to advance the compound’s development with a focus on public health impact and access. Telacebec works by targeting mycobacterial energy production, disrupting a critical pathway required for bacterial survival. Preclinical studies have demonstrated potent activity against Mycobacterium tuberculosis, as well as Mycobacterium ulcerans, the causative agent of Buruli ulcer, and Mycobacterium leprae, the causative agent of leprosy. These findings support the continued clinical development of telacebec as a potential new treatment option for diseases that disproportionately affect underserved populations worldwide.
