In the Phase 2 trial, 72% of participants who had prediabetes at the start had normal glycated hemoglobin levels at 48 weeks, compared to just 22% on placebo
However, after addition of ligands, these permutants gained specific activity and the native-like structural properties, including a large change in their melting behavior, such as lower C p values at low temperatures and the presence of a distinct heat absorption peak (Uversky et al., 1996)
