Tolerability, safety and pharmacodynamics of oral, small-molecule glucagon-like peptide-1 receptor agonist danuglipron for type 2 diabetes: A 12-week, randomized, placebo-controlled, Phase 2 study comparing different dose-escalation schemes.

AIM: To evaluate the tolerability, safety and pharmacodynamics of different dose-escalation schemes of the oral small-molecule glucagon-like peptide-1 receptor (GLP-1R) agonist danuglipron. MATERIALS AND METHODS: This Phase 2a, double-blind, placebo-controlled, parallel-group study randomly assigned adults with type 2 diabetes (T2D) treated with metformin to placebo or danuglipron (low [5-mg] or high [10-mg] starting dose, with 1- or 2-week dose-escalation steps, to target doses of 80, 120 or 200 mg twice daily [BID]) and adults with obesity without diabetes to placebo or danuglipron 200 mg BID. RESULTS: Participants with T2D (n = 123, mean glycated haemoglobin [HbA1c] 8.19%) or obesity without diabetes (n = 28, mean body mass index 37.3 kg/m2 ) were randomly assigned and treated. Discontinuation from study medication occurred in 27.3% to 72.7% of participants across danuglipron groups versus 16.7% to 18.8% for placebo, most often due to adverse events. Nausea (20.0%-47.6% of participants across danuglipron groups vs. 12.5% for placebo) and vomiting (18.2%-40.9% danuglipron vs. 12.5% placebo, respectively) were most commonly reported in participants with T2D. Gastrointestinal adverse events were generally related to danuglipron target dose and were not substantially affected by starting dose. In participants with T2D, least squares mean changes from baseline in HbA1c (-1.04% to -1.57% across danuglipron groups vs. -0.32% for placebo), fasting plasma glucose (-23.34 mg/dL to -53.94 mg/dL danuglipron vs. -13.09 mg/dL placebo) and body weight (-1.93 to -5.38 kg danuglipron vs. -0.42 kg placebo) at Week 12 were generally statistically significant for danuglipron compared with placebo (P < 0.05). CONCLUSIONS: Danuglipron resulted in statistically significant reductions in HbA1c, FPG and body weight over 12 weeks, in the setting of higher discontinuation rates and incidence of gastrointestinal adverse events with higher target doses.

The FGF21 analog pegozafermin in severe hypertriglyceridemia: a randomized phase 2 trial.

Pegozafermin, a long-acting glycopegylated analog of human fibroblast growth factor 21, is in development for the treatment of severe hypertriglyceridemia (SHTG) and nonalcoholic steatohepatitis. Here we report the results of a phase 2, double-blind, randomized, five-arm trial testing pegozafermin at four different doses (n = 67; 52 male) versus placebo (n = 18; 12 male) for 8 weeks in patients with SHTG (triglycerides (TGs), ≥500 mg dl-1 and ≤2,000 mg dl-1). Treated patients showed a significant reduction in median TGs for the pooled pegozafermin group versus placebo (57.3% versus 11.9%, difference versus placebo -43.7%, 95% confidence interval (CI): -57.1%, -30.3%; P < 0.001), meeting the primary endpoint of the trial. Reductions in median TGs ranged from 36.4% to 63.4% across all treatment arms and were consistent regardless of background lipid-lowering therapy. Results for secondary endpoints included significant decreases in mean apolipoprotein B and non-high-density lipoprotein cholesterol concentrations (-10.5% and -18.3% for pooled doses compared to 1.1% and -0.6% for placebo (95% CI: -21.5%, -2.0%; P = 0.019 and 95% CI: -30.7%, -5.1%; P = 0.007, respectively), as well as a significant decrease in liver fat fraction for pooled treatment (n = 17) versus placebo (n = 6; -42.2% pooled pegozafermin, -8.3% placebo; 95% CI: -60.9%, -8.7%; P = 0.012), as assessed in a magnetic resonance imaging sub-study. No serious adverse events were observed to be related to the study drug. If these results are confirmed in a phase 3 trial, pegozafermin could be a promising treatment for SHTG (ClinicalTrials.gov registration: NCT0441186).

Characteristics, management, and blood pressure control in patients with apparent resistant hypertension in the US.

Background: Per treatment guidelines, resistant hypertension is defined as uncontrolled blood pressure (BP) while taking 3 concomitant antihypertensives (AHTs) or controlled BP while taking ≥4 AHTs. Characteristics, AHT therapy use, and BP control were analyzed in US patients with hypertension who were prescribed ≥3 classes of AHT medications. Methods: This retrospective analysis of the Optum® Electronic Health Record Database evaluated patients ≥18 years of age with a diagnosis of hypertension classified based on the number of prescribed AHT medication classes (3, 4, or ≥5). For the primary analysis, uncontrolled hypertension was defined as systolic BP (SBP) ≥140 mmHg or diastolic BP (DBP) ≥90 mmHg. For secondary analyses, uncontrolled hypertension was defined as SBP ≥130 mmHg or DBP ≥80 mmHg. Results: 207,705 patients with hypertension and concurrent use of ≥3 AHT medication classes were included. Diuretics, beta blockers, ACE inhibitors and/or ARBs, and CCBs were the most prescribed classes; thiazides and thiazide-like agents were the most prescribed diuretics. Among patients who were prescribed 3, 4, or ≥5 AHT medication classes, approximately 70% achieved a BP goal of <140/90 mmHg; approximately 40% achieved BP <130/80 mmHg. After ≥1 year of follow-up, the number of concurrent AHT medication classes was unchanged from baseline in the majority of patients and the prevalence of uncontrolled hypertension (≥140/90 mmHg) was similar. Conclusions: This study illustrates suboptimal BP control in many patients with apparent resistant hypertension despite the use of multidrug regimens and suggests a need for new drug classes and regimens that effectively manage resistant hypertension.
