Abstract

Background & aims Glucagon-like peptide-1-based therapy is gaining widespread use for type 2 diabetes, although there are concerns about risks for pancreatitis and pancreatic and thyroid cancers. There are also concerns that dipeptidyl peptidase-4 inhibitors could cause cancer, given their effects on immune function.Methods We examined the US Food and Drug Administration's database of reported adverse events for those associated with the dipeptidyl peptidase-4 inhibitor sitagliptin and the glucagon-like peptide-1 mimetic exenatide, from 2004-2009; data on adverse events associated with 4 other medications were compared as controls. The primary outcomes measures were rates of reported pancreatitis, pancreatic and thyroid cancer, and all cancers associated with sitagliptin or exenatide, compared with other therapies.Results Use of sitagliptin or exenatide increased the odds ratio for reported pancreatitis 6-fold as compared with other therapies (P<2×10(-16)). Pancreatic cancer was more commonly reported among patients who took sitagliptin or exenatide as compared with other therapies (P<.008, P<9×10(-5)). All other cancers occurred similarly among patients who took sitagliptin compared with other therapies (P=.20).Conclusions These data are consistent with case reports and animal studies indicating an increased risk for pancreatitis with glucagon-like peptide-1-based therapy. The findings also raise caution about the potential long-term actions of these drugs to promote pancreatic cancer.

  • Pharmacovigilance databases reflect nonsubstantiated events reported by individuals and attributed to a particular drug; they do not establish a causal or even an association relationship between a drug and the event, serving instead for hypothesis generation.

    “However, these databases reflect nonsubstantiated events reported by individuals and attributed—by those individuals—to a particular drug.61–63 They do not establish a causal or even an association relationship between a drug and the event, serving instead for hypothesis generation and prompt for future investigation of disproportional increased reporting of events.”

  • In an analysis of the U.S. FDA database, the OR was 4.73 for a report of a thyroid cancer event for exenatide compared with comparators (rosiglitazone, nateglinide, repaglinide, and glipizide) (p = 0.004).

    “In their analysis, they found an OR = 4.73 for a report of a thyroid cancer event for exenatide compared with comparators (rosiglitazone, nateglinide, repaglinide, and glipizide) (p = 0.004).62”

    From Glucagon-Like Peptide-1 Receptor Agonists and Thyroid Cancer: A Narrative Review (2024) · cites this paper as [62]

    The Results (Thyroid cancer; page unavailable) report an OR of 4.73 and P = 0.004 for reported thyroid cancer with exenatide in the FDA adverse-event database. The Methods (Study Design; page unavailable) name all four drugs as controls, but the thyroid-cancer Results specify rosiglitazone as the comparator for this analysis, not the four-drug group stated in the claim.

  • In that report, the incidence of pancreatic cancer was 2.9 and 2.7 times greater with exenatide and sitagliptin, respectively, compared to other oral antidiabetic medications.

    “In that report, the incidence of pancreatic cancer was also 2.9 and 2.7 times greater with exenatide and sitagliptin, respectively, compared to other oral antidiabetic medications.”

    From Exploring the Side Effects of GLP-1 Receptor Agonist: To Ensure Its Optimal Positioning (2025) · cites this paper as [51]

    The Results (Pancreatic cancer) give the claimed 2.9-fold and 2.7-fold comparisons for exenatide and sitagliptin. But these are rates of reported adverse events, not measured pancreatic-cancer incidence; the Methods describe the FDA adverse-event reporting database, and the Discussion notes its reporting biases. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Initial observational signals from 2011 suggested an increased risk of acute pancreatitis and pancreatic cancer in patients using GLP-based therapies compared to non-users (adjusted OR 2.24, 95% CI 1.36, 3.68).

    “Initial observational signals from 2011 suggested an increased risk of acute pancreatitis and pancreatic cancer in patients using GLP-based therapies compared to non-users (adjusted odds ratio [OR]: 2.24, 95% CI 1.36, 3.68),67,68 leading the FDA to issue a warning on the pancreatic safety of GLP-1 RAs.69”

    From The expanding role of GLP-1 receptor agonists: a narrative review of current evidence and future directions (2025) · cites this paper as [67]

    The Results (page not available in our copy) report more frequent adverse-event reports of pancreatitis and pancreatic cancer with exenatide or sitagliptin than with other diabetes therapies. They do not report the claimed adjusted OR of 2.24 (95% CI 1.36–3.68), and the comparator was other therapies, not non-users. The paper cautions that its retrospective reporting analysis cannot fully account for confounding. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Searches of adverse event-reporting databases indicated a substantially higher risk for acute pancreatitis with GLP-1RA treatment.

    “The case reports of pancreatitis prompted searches of adverse event–reporting databases (65), which indicated a substantially higher risk for acute pancreatitis with GLP-1RA treatment.”

    From The science of safety: adverse effects of GLP-1 receptor agonists as glucose-lowering and obesity medications (2026) · cites this paper as [65]

    The Results (Control Events, Pancreatitis) report substantially more frequent pancreatitis adverse-event reports for exenatide and sitagliptin than for comparator therapies. The Discussion cautions that the FDA AERS database has reporting biases and is not ideal for comparing adverse-event rates. The finding therefore supports a reporting signal, not an established higher clinical risk; it also combines exenatide with sitagliptin rather than examining GLP-1 receptor agonists alone.

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.
