Single-dose CR059, a circular RNA-encoded GLP-1 analogue, enables sustained exposure and prolonged body weight reduction in non-human primates (EASD 2026) - "Materials and Male healthy rhesus monkeys (n=2/group, baseline body weight ~7-8 kg) received single subcutaneous doses of CR059 (180 or 540 µg/kg) or reference exenatide (Byetta, 0.6 µg/kg, twice daily for 5 weeks). Single-dose CR059 demonstrates rapid and robust body weight-lowering activity in rhesus monkeys, with clear dose- dependent effects and sustained plasma GLP-1RA exposure. Its long-acting profile allows for monthly dosing, potentially reducing gastrointestinal side effects such as nausea and vomiting, and supporting continuous therapy as an alternative or follow-up to existing GLP-1RAs. Together, the PK, PD, and ddPCR data highlight CR059's potential as a durable circRNA-based GLP-1 therapy for weight management and other metabolic diseases."

Quantitative analysis of free polyethylene glycols in PEGylated peptides using reverse-phase high-performance liquid chromatography and charged aerosol detection. (PubMed, PLoS One) - "Herein, systematically optimized reverse-phase high-performance liquid chromatography (RP-HPLC) coupled with charged aerosol detection (CAD) was developed and validated for the quantification of free PEG in three representative PEGylated peptide therapeutics: PEG-loxenatide, pegmolesatide, and visepegenatide...Practical applicability was confirmed by analyzing multiple drug batches and accelerated stability samples.A Wilcoxon signed-rank test showed no statistically significant difference between the results obtained under the default and co-optimized settings (P > 0.05), indicating that the two settings produced comparable results under the conditions evaluated. The proposed HPLC-CAD method provides a practical analytical approach in the analysis of PEGylated peptide pharmaceuticals by achieving a linearized CAD response through PFV and PL co-optimization, providing an effective approach for free PEG quantification in routine quality control."

Efficacy and safety of incretin co-agonists: Transformative advances in cardiometabolic healthcare. (PubMed, World J Cardiol) - "The GLP-1 receptor agonists (GLP-1RAs), namely liraglutide, dulaglutide, albiglutide, exenatide, and semaglutide, have been found to have beneficial effects on glycated hemoglobin, weight, lipid profile, and liver fat and thereby improving cardiometabolic health. Other drugs of the same group in development include Orforglipron, which has a high weight loss efficacy (-15% weight reduction). Long-acting GLP-1RAs in trials are Ecnoglutide, Efpeglenatide, TG103, and Visepegenatide...Retatrutide and Efocipegtrutide belong to this novel group of drugs. The newer drugs in the broad category of incretin co-agonists include the GLP-1/amylin receptor agonist like CagriSema and Amycretin, oral GLP-1 agonists other than semaglutide, and the peptide YY/GLP-1 receptor dual agonists. The profound biochemical and weight loss outcomes associated with incretin co-/poly-agonists are expected to translate into outstanding cardiometabolic benefits, the theme of this evidence review."

A Phase 1b/2a Trial to Assess the Safety, Tolerability, Pharmacokinetics, and Efficacy of PB-718, a GLP-1R/GCGR Dual Agonist in Subjects with Obesity (ADA 2024) - P1/2 | "Introduction: PB-718 is a fixed dose combination of PB-119 (GLP-1 receptor agonist) and PB-722 (glucagon receptor agonist in clinical development. PB-718 was safe, had predicted PK profile, and led to greater reductions in BW, HbA1c, blood lipids, uric acid, liver fat content and visceral fat mass. These data highlight the potential for PB-718 to provide additional benefit, and support the development of PB-718 as a promising treatment for obesity and NASH."
