Lung Cancer Risk in Type 2 Diabetes With COPD: SGLT2 Inhibitors vs. Sulfonylureas

21,692 participantsStarted 2009-01-01

Plain-language summary

The goal of this observational study is to learn if a specific diabetes medicine can lower the risk of lung cancer in people with type 2 diabetes and chronic obstructive pulmonary disease (COPD). The main question it aims to answer is: \- Does taking medicines called SGLT2 inhibitors lower the chance of getting lung cancer compared to medicines called sulfonylureas? Researchers will compare the medical records of people taking SGLT2 inhibitors to those taking sulfonylureas to see if the SGLT2 group has fewer cases of lung cancer. Participants will not need to visit a doctor or take new medicines for this study. Researchers will use information from existing medical records to answer the research question.

Inclusion Criteria: * Adults aged ≥40 years with prior COPD (from 2009) and newly diagnosed diabetes who initiated SU or SGLT2i between January 1, 2014 and December 31, 2023 Exclusion Criteria: * Pre-existing * ESRD * Cancer * Concurrent prescribing of the study drugs at the index date * Exposure to the drugs of interest during the year preceding the index date * Death or cancer incidence within a month In the sensitivity analysis, we are planning to substitute sulfonylurea to DPP4 inhibitors.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
