Anti-Human GLP-1(aa 9-18) monoclonal antibody

Purpose: Hypoglycemia is a common and sometimes life-threatening adverse event associated with insulin, sulfonylurea, and meglitinide therapies. In patients who are disoriented or unconscious, treatment with injectable glucagon is recommended, along with a call for emergency medical assistance. However, limitations of this formulation include difficulty with reconstitution and an unwillingness to administer an injection. In July 2019, intranasal glucagon was approved for use in the acute treatment of severe hypoglycemia in patients >= 4 years of age with diabetes. The purpose of this systematic review was to describe the efficacy, usability, and tolerability of intranasal glucagon 3 mg in patients with diabetes. Methods: To identify studies, the following databases were systematically searched: Ovid MEDLINE, Embase, CINAHL, Web of Science Core Collection, Cochrane CENTRAL (EBSCO), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform, from inception to March 3, 2020. Comparative studies included patients with diabetes and an active comparator. Usability studies enrolled participants who used a device for glucagon administration. Findings: Ten studies met the inclusion criteria. In 5 comparative studies in insulin-induced hypoglycemia (intranasal vs injectable glucagon), the criteria for successful treatment varied. In 3 studies, it was defined as an increase in blood glucose of >= 70 mg/dL (3.9 mmol/L) or an increase of >= 20 mg/dL (1.1 mmol/L) within 30 min of glucagon administration. In 1 study, the criteria were stricter, with success defined as an increase in blood glucose of >= 27 mg/dL (>= 1.5 mmol/L) within 15 min. In the pediatrics study, success was defined as an increase in blood glucose of >= 25 mg/dL (1.4 mmol/L) within 20 min. In 2 studies of intranasal glucagon monotherapy in clinical practice, the primary end point was the percentage of patients who awakened or returned to normal status within 30 min of intranasal glucagon administration. In these 7 studies, almost all of the participants met the criteria for success as defined in their respective studies. The mean time to treatment success was between 10 and 20 min with intranasal and injectable glucagon. Nausea and vomiting were common adverse events with both formulations; watery eyes and runny nose occurred more frequently with intranasal glucagon. In 3 simulation studies, caregivers and noncaregivers administered intranasal glucagon within 1 min versus 1.3-5 min with IM glucagon. Implications: In patients who are disoriented or unconscious, treatment with injectable or ready-to-use intranasal glucagon increases blood glucose within 15-30 min. Intranasal glucagon was preferred by most caregivers and noncaregivers due to its ease of use. Additional studies of intranasal glucagon in younger patients (1-<3 years of age), pregnant women, and in comparison with SC glucagon are needed to further clarify bioavailability, efficacy, and tolerability (Clin Ther. 2020;42:e177ee208) (c) 2020 Elsevier Inc.

This work demonstrates synthetic strategies for the incorporation of a synthesized pyrimidine glucagon-like peptide-1 (GLP-1) agonist into alginate-coated ZIF-8. The prepared pyrimidine GLP-1 agonist used for the treatment of diabetes type II, was trapped inside polymer coated ZIF-8. The encapsulation of the GLP-1 agonist was confirmed by UV-visible and FT-IR spectroscopies. Furthermore, the release kinetics of GLP-1 agonist drug from alginate-coated ZIF-8 were investigated in phosphate-buffered saline at 37 degrees C at pH 8 and 1.5. The alginate-coated ZIF-8 exhibited much faster drug release at basic pH than at pH 1.5, indicating the potential of the alginate-coated ZIF-8 system to overcome the fast degradation at acidic pH of the stomach and improve the drug's activity. This study may open the way for the synthesis of new metal organic frameworks (MOFs) to enhance drug delivery systems.
