News Brief: TrialNet Explores Plasmid Therapy for Type 1 Diabetes

Phase 1 study now recruiting adults diagnosed in past 4 years

JANUARY 14, 2021—TrialNet is testing a new plasmid therapy in adults diagnosed with type 1 diabetes in the past 4 years.

Designed by Novo Nordisk, NNC0361-0041 is a recombinant supercoiled plasmid encoding four human proteins: pre-proinsulin (PPI), transforming growth factor β1 (TGF-β1), interleukin-10 (IL-10), and interleukin-2 (IL-2). Preclinical findings show these therapies working together might retrain the immune system to stop attacking insulin-producing beta cells.

This is a Phase 1 study, meaning it is the first time this plasmid is being tested in people. If the study results in no safety concerns, TrialNet plans to conduct a larger study to see if the same treatment can slow or stop disease progression in high-risk individuals prior to type 1 diabetes diagnosis.
