A team of researchers from the Indian Institute of Technology (IIT) Guwahati, the National University of Singapore, and the University of Michigan has introduced a groundbreaking clinical trial method that could transform personalized healthcare. The new multi-stage trial approach adapts treatments based on real-time patient responses, allowing for more effective and customized medical care.
The study, recently published in the journal Biometrics, is co-authored by Palash Ghosh and Rik Ghosh from IIT Guwahati, Bibhas Chakraborty from Duke-NUS Medical School at the National University of Singapore, and Inbal Nahum-Shani and Megan E. Patrick from the University of Michigan, USA.
The research focuses on Dynamic Treatment Regimes (DTRs) developed through Sequential Multiple Assignment Randomized Trials (SMARTs). These frameworks help improve treatment strategies for patients who respond differently to various therapies over time. Unlike conventional treatment plans, DTRs adjust treatment approaches dynamically based on individual patient progress. For example, if a diabetes patient does not respond well to an initial drug, the DTR method may suggest switching medications or combining therapies based on real-time health indicators like blood sugar levels.
Explaining the significance of the study, Palash Ghosh, Assistant Professor in the Department of Mathematics at IIT Guwahati, said that multi-stage clinical trials play a crucial role in designing effective treatment plans. SMART trials involve multiple stages, where patients are reassigned to different treatments depending on their responses to earlier interventions. Unlike traditional trials that assign equal numbers of patients to different treatment options, this new approach adjusts patient allocation in favor of more effective treatments. This reduces the risk of unnecessary treatment failures and ensures better health outcomes.
“Our adaptive randomization method dynamically assigns patients to treatment arms based on real-time trial data. This means patients are more likely to receive effective treatments while maintaining scientific accuracy in the research,” said Ghosh. He further explained that the method improves both short-term and long-term patient care by reducing treatment failures and personalizing medical solutions.
The researchers believe this innovation will encourage greater patient participation in clinical trials since participants will receive treatments tailored to their specific needs. Beyond clinical medicine, this approach could also be valuable in public health interventions, such as personalized recovery plans for substance abuse and chronic disease management.
Looking ahead, the research team is collaborating with Indian medical institutions to conduct SMART trials for mental health treatment using traditional Indian medicines. This effort aims to explore how ancient healing practices can be integrated into modern, data-driven treatment methods to improve patient outcomes.
