Epidemiological Assessment of the Risk for Pancreatic Cancer Associated With the Use of Semaglutide in Patients With Type 2 Diabetes - A Cohort Study Based on Nordic Registry Data

Inclusion Criteria: * Use of semaglutide or initiation of active comparators from when the first subject is dispensed semaglutide in the respective country (2018) until December 31, 2022. Initiation is defined as no previous prescription of a drug with the same active ingredient in the past 10 years as recorded in the national prescription registries. Previous use of the same class of drug is however accepted. Further, a patient who shift from Ozempic® to Rybelsus® or vice versa will be considered a continued user in the semaglutide group. * At least two prescriptions of either semaglutide or active comparators (at the level of the active ingredient) with the second prescription filled less than one year after the initial prescription. Two prescriptions filled at first day of treatment will, however, only be counted as one prescription. * 18 years or older at the cohort entry date. The cohort entry date is defined as the dispensing date of the initial prescription (i.e. treatment initiation). * Ten years or more of continuous residency in the country of residence before initiation of semaglutide or active comparators. Exclusion Criteria: Patients with rare but strong risk factors for developing pancreatic cancer are excluded. Therefore, patients with any history of the following conditions (identified according to 10th version of International Classification of Diseases \[ICD-10\]) before cohort entry date (based on the last 10 years of data or more) are excluded: * A history of any cancer except non-melanoma skin cancer * Acute pancreatitis * Alcohol-induced chronic pancreatitis * Other chronic pancreatitis * Cystic fibrosis * Other phacomatoses, not elsewhere classified (including Peutz-Jeghers syndrome and Von Hippel-Lindau syndrome) * Neurofibromatosis (non-malignant, Von Recklinghausen disease) In addition, the following patients are excluded: * Patients with a history of pancreatic cancer as these patients are no longer at risk for an incident pancreatic cancer * Patients who initially started insulin as first-line antidiabetic treatment and who did not add on or switch to non-insulin treatment within 3 months. Those initiating insulin as first-line treatment during the study period is disregarded in terms of study inclusion, although they may be included upon initiating additional therapy, provided it is started within three months. * Patients with polycystic ovary syndrome (PCOS) * Patients with gestational diabetes * Patients who meet one of the conditions used as exclusion criteria listed above (except acute and chronic pancreatitis) after cohort entry date but before start of follow-up (i.e. during the first year after treatment initiation)
