TerminatedPhase 1

A Clinical Trial of the Study Medicine (PF-07081532) in People With Diabetes and Kidney Dysfunction

Stopped: The decision to terminate clinical development of lotiglipron is based on pharmacokinetic data from Phase 1 drug-drug-interaction studies and laboratory measurements of elevated transaminases in these Phase 1 studies as well as a Phase 2 study.

Plain-language summary

The purpose of this study is to understand the effects of kidney functional impairment may have on the study medicine (PF-07081532). People with certain level of kidney functional impairment may process PF-07081532 differently from healthy people. PF-07081532 is developed as a potential treatment for type II diabetes. Participants will take the study medicine as a tablet by mouth once at the study clinic and then will stay at the study clinic for about 7 days. During that time, the study team will monitor their treatment experience and take some blood samples to test the level of PF-07081532. This will help us understand if certain degree of kidney functional impairment will have an effect on the study medicine PF-07081532.

Inclusion criteria

. Stable renal function (for participants not on dialysis) defined as ≤25% difference between 2 measurements of BSA-unnormalized eGFR
. A prior diagnosis of T2DM with an HbA1c ≥6% and ≤10.5%
. Women may be of child-bearing potential
. BMI of 17.5 to 45.4 kg/m2
. NORMAL FUNCTION (GROUP 1): Normal renal function (mean eGFR ≥90 mL/min) based on an average of measures from Screening visits S1 and S2 (eGFR should be calculated using the 2021 CKD EPI Scr-Scys combined equation:

Exclusion criteria

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.
