BTI320: BTI320, also known as SUGARDOWN®, is derived from galactomanan which blocks key enzymes that break down carbohydrate in the gut. BTI320 therefore helps to slow down the absorption of carbohydrates to lower post-meal blood sugar.

Change in Serum Fructosamine in Subjects Treated With Low Dose and High Dose BTI320 Compared With Placebo

Changes in 3-hour post-prandial glucose incremental area under curve on continuous glucose monitoring system from baseline to Week 16.
Note that this is not a pharmacokinetic study and this is not pharmacokinetic data as we are not measuring drug levels. Here we are examining glucose levels after meals as one of the anticipated glycemic outcomes of using glucose-lowering therapy (BTI320 in this case). With data-analysis based on continuous glucose monitoring, it is conventional to present post-prandial (i.e. post-meal) glucose incremental area under curve at up to 3 hours. It is not meaningful to look at post-meal glucose changes at more than 3 hours after meal for the obvious reason that subject might have taken another meal by then.
