    According to a study published in the British Medical Journal in 2020, the number of diabetic patients in China has exceeded 129.


    This year marks the 100th anniversary of the discovery of insulin by humans.

    Teplizumab (PRV-031) is a humanized anti-CD3 monoclonal antibody that can prevent the formation of CD3-TCR complexes, thereby preventing T cells from attacking pancreatic β cells


    On May 27, Teplizumab was approved by the FDA Endocrine and Metabolic Drug Advisory Committee (EMDAC) with 10 (for): 7 (against) votes


    Clinical efficacy

    Clinical efficacy

    The clinical data published in the New England Journal of Medicine [2] showed that among more than 1,000 patients with type 1 diabetes, more than 800 patients received teplizumab treatment


    Specifically, compared with placebo, a single 14-day course of teplizumab treatment can significantly delay the onset of T1D.


    In addition, in the key TN-10 trial [3], compared with placebo, templizumab can delay the onset of disease in patients with insulin-dependent T1D but not yet symptomatic by an average of about 3 years

    Patients with T2D have an increased risk of cardiovascular disease, kidney disease, and other complications


    SGLT-2 (sodium-glucose cotransporter 2) inhibitors and GLP-1 (glucagon-like peptide 1) receptor agonists are two relatively new types of hypoglycemic drugs.


    Therefore, on May 11, the "British Medical Journal" published an international clinical practice guide, recommending SGLT-2 inhibitors or GLP-1 receptor agonists for adult type 2 diabetes [7]


    Guide recommendations:

    (1) With ≤3 cardiovascular risk factors, but no CVD (cardiovascular disease) or CKD (chronic kidney disease): It is not recommended to initiate SGLT-2 inhibitor or GLP-1 receptor agonist therapy (weak recommendation)


    (2)>3 cardiovascular risk factors, but no CVD or CKD: It is recommended to start using SGLT-2 inhibitors (weak recommendation), and it is not recommended to start GLP-1 receptor agonist therapy (weak recommendation)


    (3) Diagnosed CVD or CKD: It is weakly recommended to start using SGLT-2 inhibitors and GLP-1 receptor agonists
    .

    (4) Diagnosed CVD and CKD: It is strongly recommended to start using SGLT-2 inhibitors, and it is weakly recommended to start using GLP-1 receptor agonists
    .

    Cardiovascular risk factors include: age> 60 years, male, Asian, African or Hispanic, family history of cardiovascular disease or kidney disease, poor control of glycosylated hemoglobin (>6.
    5%), smoking, poor control of hypertension ( >140/90 mm Hg), dyslipidemia (total cholesterol ≥5.
    2 mmol/L)
    .

    GCGR/GLP-1R dual agonist clinical trial application was accepted by CDE

    GCGR/GLP-1R dual agonist clinical trial application was accepted by CDE

    On May 14, the official website of the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) of China showed that AstraZeneca applied for a clinical trial application for a new class 1 drug, cotadutide injection, and was accepted [8]
    .

    Cotadutide is a dual agonist of glucagon receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R)
    .
    GCGR and GLP-1R are members of the G protein-coupled receptor family.
    They are two important "regulators" for maintaining the balance of human blood sugar: in the state of starvation, GCGR can increase human blood sugar levels by binding to its ligand glucagon ; And GLP-1R mainly plays a role after ingestion, by combining with its ligand glucagon-like peptide-1 to stimulate insulin secretion, so that postprandial blood glucose is reduced and maintained at a normal level
    .

    In a randomized, double-blind, phase 2a study in patients with type 2 diabetes, it was preliminarily confirmed that its hypoglycemic effect is mediated by enhanced insulin secretion and delayed gastric emptying
    .
    More clinical research results show that in overweight patients with type 2 diabetes with fatty liver, cotadutide has shown the effect of reducing liver fat levels and reducing liver fibrosis [9]

    GLP-1/GIP dual target agonist, Huadong Medicine introduced USD 28 million

    GLP-1/GIP dual target agonist, Huadong Medicine introduced USD 28 million

    On June 2nd, Huadong Medicine announced that it has reached a cooperation with Japanese SCOHIA company, with a US$4 million down payment and a maximum of US$24 million in development, registration and sales milestone payments to obtain GLP-1/GIPR dual target excitement in clinical phase I The exclusive development, production and commercialization rights of the antidiabetic drug SCO-094 in 25 Asia-Pacific countries and regions (excluding Japan) including China, South Korea and Australia [10]
    .

    Dual target agonists are biological molecules that specifically bind to two receptors at the same time
    .
    When combined with the target, it can activate downstream pathways, enhance the biological effect of the target, and simultaneously give play to the advantages of the two targets, which has a dual effect.
    It has been a focus of attention in the field of diabetes in recent years
    .

    SCO-094 is a specific dual-target agonist that selectively activates GLP-1 receptor and GIP receptor, stimulates downstream pathways, and produces biological effects such as blood sugar control and weight loss
    .
    Preclinical in vitro studies have shown that SCO-094 has strong target binding activity and cell biological activity
    .
    The results of drug efficacy in animals show that it has a powerful hypoglycemic effect, weight loss and liver function improvement, lower triglycerides and inhibit liver steatosis
    .

    In terms of clinical research, SCO-094 is conducting a randomized, placebo-controlled, double-blind, single-center evaluation of the tolerability, safety, pharmacokinetics and pharmacodynamics of a single subcutaneous administration in patients with type 2 diabetes in the United Kingdom.
    Clinical trials
    .
    In clinical trials, the expected hypoglycemic effect has been observed, and currently all subjects have not experienced hypoglycemia.
    This clinical trial is still blind
    .

    With the development of treatment concepts and the continuous production of innovative drugs, it has become the common goal of diabetes treatment and drug research and development to provide patients with hypoglycemic options that take into account the benefits of cardiovascular metabolism and high compliance
    .
    It is believed that in the near future, with the further deepening of scientific research and interdisciplinary and cross-border cooperation, the treatment of diabetes, an ancient disease, will fundamentally change
