Scientists are closing in on new treatments for a debilitating lung disease that slowly robs patients of their ability to breathe.
The therapies, originating from a 2017 breakthrough by Duke-NUS Medical School and its Academic Medicine partner SingHealth, were licensed to German pharmaceutical company Boehringer Ingelheim and have since progressed into phase two clinical evaluation, placing the drug development programme among the few discoveries from Singapore to reach this stage.
The breakthrough showed that interleukin-11 (IL-11), a gene long believed to be protective, was in fact causing damage instead.
Assistant professor Anissa Widjaja, the molecular biologist who co-led the five-year research, explains: “We found that IL-11 plays a key role in driving scarring, chronic inflammation and organ injury – three processes that sit at the heart of many age-related diseases and organ failure.”
The team eventually found that blocking IL-11 did not only slow disease progression but could also reverse damage and help organs repair themselves.
This paradigm shift has opened the door to therapies that could potentially restore function to organs such as the liver and kidneys, too – with potential applications across a range of complex chronic diseases.
“It’s less about turning back the clock but about reducing the years people spend in poor health, frailty, weakness and disease,” says Prof Widjaja.
Prof Widjaja credits the discovery to the school’s support and collaborative culture, saying: “Duke-NUS has played a very critical role in enabling my research and how I think about impact”.
Competitive grants and internal funding supported her team’s work from its earliest stages, alongside expertise in intellectual property, industry engagement, and legal and licensing. These less visible elements often determine whether a scientific idea becomes a viable therapy, she says.
She adds: “As an early career scientist at that time, having access to that ecosystem was incredibly formative.”
