Daniel Drucker

The first to identify the actions of GLP-1 and GLP-2, enabling medicines for diabetes, obesity and intestinal disorders

Daniel Drucker

Revealed the potential for gut hormones to achieve dramatic clinical outcomes in the treatment of life-limiting and life-threatening metabolic and intestinal disorders

Short bowel syndrome, a disorder affecting newborns and adults recovering from major intestinal resection, has increased more than two-fold in the last 40 years, reflecting complications in babies born prematurely, and an increase in surgical interventions for severe Crohn’s disease. Dr. Drucker’s discoveries helped to develop teduglutide, a GLP-2-based medication, providing long-term therapy for the treatment of adults and children. Approximately one of every five patients on teduglutide in the real world has completely discontinued intravenous feeding, leading to remarkable improvement in quality of life. Dr. Drucker has also contributed to the development of new classes of therapeutic medications for type 2 diabetes and obesity, prescribed to more than a hundred million patients worldwide and transforming the treatment of metabolic disease. A profoundly gifted laboratory researcher, Dr. Drucker has personally translated advanced scientific discoveries into real-world clinical applications, substantially improving the lives of patients. A much-honoured clinical-scientist at the Lunenfeld-Tanenbaum Research Institute of Mt. Sinai Hospital, and a Professor of Medicine at the University of Toronto, Dr. Drucker’s laboratory studies have revolutionized the treatment of metabolic disorders and exemplify exceptional bench-to-beside translation of scientific research.

Key Facts

Elucidated the role of GLP-1 (glucagon-like peptide 1) in insulin secretion leading to the development of patented medications for the treatment of type 2 diabetes

GLP-1 based medications facilitated weight loss and reduced the incidence of cardiovascular complications extending their application to effective treatment of obesity rivaling outcomes of bariatric surgery

Emerging evidence suggests GLP-1 acting on the brain is neuroprotective and early studies in disorders such as Parkinson’s disease show promise; Phase 3 trials in Alzheimer’s are also underway

Discovered medical application of GLP-2 in stimulating nutrient absorption leading to development of teduglutide medications providing therapeutic treatment for short bowel disease freeing many patients from reliance on intravenous feeding

Professional timeline

Impact on lives today

Short bowel syndrome affects newborns and adults recovering from intestinal resection surgery and its incidence has significantly increased. Patients who were once tethered to intravenous feeding are now often free to live improved lives due to Dr. Drucker’s discoveries, which contributed to the development of teduglutide medications. Dr. Drucker has also advanced the treatment of Type 2 diabetes and obesity with therapeutic medications revolutionizing the treatment of metabolic disease. Millions of patients worldwide suffering from metabolic illnesses have been helped by these new medications.
