`Treatment with a DPP-IV Inhibitor, NVP-DPP728, Increases
`Prandial Intact GLP-1 Levels and Reduces Glucose Exposure in

`NVP-DPP728 is a highly selective, orally active inhibitor of dipeptidyl
`peptidase-IV (DPP-IV) designed to augment the glucose-lowering activity
`of endogenously secreted GLP-1. Recent studies have demonstrated that
`NVP-DPP728 prevents N-terrninal degradative inactivation of GLP-1 and
`improves glucose tolerance in insulin-1'esistant rats. The present crossover
`trial evaluated the single dose pharmacodynamics of NVP-DPP728 admin-
`istered to 12 healthy normoglycemic volunteers. Afier an overnight fast,
`subjects were administered 100 mg NVP-DPP728 or placebo, followed 30
`minutes later by a 1000 kcal solid meal (23g protein, 42g fat, 36g carbo-
`hydrate, standard FDA breakfast). Blood samples were obtained predose
`V and for up to 24 hours afier each dose for analysis of plasma glucose and
`insulin levels and also for active, undegraded GLP-1 levels by direct
`ELISA (Linco Research). NVP-DPP728 increased peak plasma levels of
`active GLP-1 (l5i2 vs. 9i2 pmol/1, p = 0.018) and also increased active
`GLP-1 prandial exposures, AUCGu,_,(04,,) (28i4’vs. l4i4 pmol.l‘l.h'1, p <
`0.0001). Prandial glucose excursions above baseline were reduced by
`NVP-DPP728 relative to placebo (l2i3 vs. 20i4 mg.dl".h", respectively,
`p = 0.04), while glucose excursions below baseline were unchanged (-
`22i4 vs. -16:4, p=0.3). Insulin excursions were not affected. No clinical-
`ly significant adverse events were observed. In addition, administration of
`NVP-DPP728 to fasting individuals was unaccompanied by-clinically sig-
`nificant changes in plasma glucose levels.
`Thus NVP-DPP728 increased prandial active GLP-1 levels with con-
`comitant reduction in prandial glucose exposure in normal subjects with-
`out causing hypoglycemia. These results provide the first direct clinical
`demonstration that DPP-1V inhibition is a viable new pharmacological
`approach for potentiating endogenous GLP-1 activity, and support the
`investigation of the glucose-lowering potential of NVP-DPP728 for the
`treatment of type 2 diabetics.

`decreases of 2 -0.7% for the 5mg or 10mg doses. The overall tolerability
`profile of GI262570 was similar to that observed with other PPAR7 ago-
`nists, with dose-related weight gain, hemoglobin decreases, and peripher-
`al edema. These data suggest that GI262570 will have clinical 11tility in the
`treatment of T2DM.

`Monotherapy with GI262570, a Tyrosine-Based Non-Tliiazolidinedione
`PPAR'yAgonist, Significantly Reduces Triglyceride and Increases HDL-

`GI262570 is a novel, non-thiazolidinedione, L-tyrosine-based peroxi-
`some proliferator-activated receptor gamma (PPAR7) agonist
`that
`is
`~l000-fold more selective for human PPAR7 compared to the human
`PPAROL isoform. A total of 376 Type 2 diabetes mellitus (T2DM) patients
`were randomized to receive either placebo (P) or one of 5 daily doses of
`GI262570 (0.25, 1, 2, 5, or 10mg) in a 12-week double-blind placebo-con-
`trolled study. Mean baseline fasting triglyceride (TG) and high-density
`lipoprotein cholesterol (HDL-C) concentrations are listed in the table.
`Approximately 60% of T2DM patients had mild fasting hypertriglyc-
`eridemia (HT) defined as TG > 150 mg/dL. Twelve weeks of treatment
`with GI262570 resulted in significant metabolic improvement in fasting
`TG and HDL-C (see table) along with changes in glycemic parameters that
`are described in a separate abstract. The maximum reduction in TG was
`achieved within 4 weeks and the effect was maintained over 12 weeks.
`While metabolic improvement in TG and HDL-C levels \vas observed
`across the range of T2DM patients regardless of baseline TG status, the
`greatest reductions were observed in subjects with mild/moderate HT.
`Apolipoprotein B levels fell by 8-14% for the 5mg and ,l0mg doses and
`there was also a non-significant decrease in LDL-C at these two GI262570
`doses. These findings suggest that GI262570 will enhance overall meta-
`bolic control for T2DM patients by improving the high TG/low HDL-C
`dyslipidemia associated with T2DM as \vell as by improving hyper-
`glycemia.

`Rosiglitazone Liver Safety Update
`HAROLD E. LEBOVITZ,“ 2 ALAN sALzMAN,‘» 2 Brooklyn, NY;
`Collegeville, PA
`Rosiglitazone is a potent thiazolidinedione for the treatment of type 2
`diabetes. The thiazolidinedione troglitazone has been associated with
`hepatotoxicity, including liver failure and hepatic-related deaths. To date,
`no signal of hepatotoxicity has been seen with rosiglitazone, which has
`been extensively evaluated.
`The incidence in rosiglitazone-treated patients ofALT elevations greater
`than 3x the upper limit of normal (ULN) \vas low and similar to place-
`bo/comparators at the time of FDA filing in November 1998, at which time
`total exposure to rosiglitazone was 3600 patient years. Subsequently, expo-
`sure to rosiglitazone in clinical trials has substantially increased and as of
`November 1999 comprised over 5000 patient years including more than
`1000 patients treated for Z 2 years. For all rosiglitazone-treated patients
