Abstract

Context: Cotadutide is a dual receptor agonist with balanced glucagon-like peptide-1 and glucagon activity. Objective: To evaluate different doses of cotadutide and investigate underlying mechanisms for its glucose-lowering effects. Design/setting: Randomized, double-blind, phase 2a study conducted in 2 cohorts at 5 clinical trial sites. Patients: Participants were 65 adult overweight/obese patients with type 2 diabetes mellitus; 63 completed the study; 2 were withdrawn due to AEs. Intervention: Once-daily subcutaneous cotadutide or placebo for 49 days. Doses (50–300 µg) were uptitrated weekly (cohort 1) or biweekly (cohort 2). Main outcome measures: Co-primary end points (cohort 1) were percentage changes from baseline to end of treatment in glucose (area under the curve from 0 to 4 hours [AUC0–4h]) post–mixed-meal tolerance test (MMTT) and weight. Exploratory measures included postprandial insulin and gastric emptying time (GET; cohort 2). Results: Patients received cotadutide (cohort 1, n = 26; cohort 2, n = 20) or placebo (cohort 1, n = 13; cohort 2, n = 6). Significant reductions were observed with cotadutide vs placebo in glucose AUC0–4h post MMTT (least squares mean [90% CI], −21.52% [−25.68, −17.37] vs 6.32% [0.45, 12.20]; P < 0.001) and body weight (−3.41% [−4.37, −2.44] vs −0.08% [−1.45, 1.28]; P = 0.002). A significant increase in insulin AUC0–4h post MMTT was observed with cotadutide (19.3 mU.h/L [5.9, 32.6]; P = 0.008) and GET was prolonged on day 43 with cotadutide vs placebo (t½: 117.2 minutes vs −42.9 minutes; P = 0.0392). Conclusion: These results suggest that the glucose-lowering effects of cotadutide are mediated by enhanced insulin secretion and delayed gastric emptying. Trial Registration: ClinicalTrials.gov, NCT03244800.

  • Clinical research on GLP-1/glucagon receptor co-agonists reveals clear decreases in amino acid levels.

    “Clinical research on GLP-1/ glucagon receptor co-agonists also reveals clear decreases in amino acid levels (Parker et al, 2020;Simonsen et al, 2022).”

    From Emerging pharmacotherapies for obesity: A systematic review (2025) · cites this paper as Parker et al, 2020

    The Results report a significant decrease in alanine with cotadutide versus placebo by day 49. They describe decreases in several other amino acids as numerical, not significant, so this paper does not establish clear decreases in amino acid levels generally. (LLM, conf=0.85)

    “Clinical research on GLP-1/ glucagon receptor co-agonists also reveals clear decreases in amino acid levels (Parker et al, 2020;Simonsen et al, 2022).”

    From Emerging pharmacotherapies for obesity: A systematic review (2025) · cites this paper as Parker et al, 2020

    The Results (page unavailable) report a significant decrease in alanine with cotadutide versus placebo. They describe decreases in other amino acids as numerical, so this paper does not establish clear decreases across amino acid levels generally. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Clinical trials of once-daily GLP-1R/GcgR co-agonists cotadutide and SAR425899 have generated guarded optimism over the modest effects on weight reduction (<10% after 4-6 weeks of treatment).

    “data from clinical trials of once-daily GLP-1R/GcgR co-agonists cotadutide (previously MEDI0382) [[21], [22], [23]] and SAR425899 [24,25] have generated guarded optimism over the modest effects on weight reduction (<10% after 4–6 weeks of treatment)”

    From Next generation GLP-1/GIP/glucagon triple agonists normalize body weight in obese mice (2022) · cites this paper as [22]

    The Results report weight loss of 3.41% with cotadutide versus 0.08% with placebo, supporting a modest reduction below 10%. The study administered once-daily cotadutide for 49 days (seven weeks), so it does not support the claim’s 4–6-week treatment window. The citation is attached to cotadutide, not SAR425899. (LLM, conf=0.86)

  • Cotadutide effectively lowered blood sugar levels and reduced weight in obese individuals and T2DM patients, increased insulin secretion, delayed gastric emptying, with the most common side effects being dose-dependent gastrointestinal symptoms (nausea and vomiting).

    “Cotadutide effectively lowered blood sugar levels and reduced weight in obese individuals and T2DM patients, increased insulin secretion, delayed gastric emptying, with the most common side effects being gastrointestinal symptoms (nausea and vomiting), which were dose-dependent [99,100].”

    Experimental — accuracy not yet measured
  • A phase IIa study showed that cotadutide reduced glucose levels in those with obesity and T2DM, with the mechanism being greater insulin secretion and delayed gastric emptying.

    “There were two further phase IIa studies evaluating cotadutide with the first one showing that it reduced glucose levels in those with obesity and T2DM with the mechanism being greater insulin secretion and delayed gastric emptying [46].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
