A Trial to Learn How Safe AZD9550 is in People With Type 2 Diabetes Who Are Overweight or Obese

• Status: Recruiting
• Trial end date: 2025-04-04
• Target enrollment: 0
• Participant gender: All

Summary

AZD9550 is in early development for the treatment of NASH, a type of liver disease that commonly affects overweight and obese patients who have T2DM.

The purpose of this study is to investigate the safety, tolerability, and effects of increasing doses of AZD9550 in overweight and obese participants aged 18 through 65 years living with T2DM, and to investigate how AZD9550 is absorbed, distributed, and eliminated from the body.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Part D only: Participants who are diagnosed with T2DM, have inadequate glycaemic control with diet and exercise. Participants who are prescribed an oral anti-diabetic agent such as metformin, a DPP IV inhibitor, sulphonylurea, glinides, alphaglucosidase inhibitors, and an SGLT2 inhibitor may be eligible to enter the study following a washout of 4-weeks or 5-half lives (whichever is longer) washout period.

≤75 mmol/mol (6% to 9%).

3. Participants with T2DM treated with a GLP-1RA within 3 months of screening.

4. History of any clinically important disease or disorder which, in the opinion of the investigator, may either put the participant at risk because of participation in the study, or influence the results or the participant's ability to participate in the study.

5. Serum calcitonin suggestive of thyroid C-cell hyperplasia (calcitonin level > 50 ng/L), medullary thyroid carcinoma, or history or family history of multiple endocrine neoplasia at screening.

6. History or presence of GI, renal, or hepatic disease (with the exception of Gilbert's syndrome), or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs, as judged by the investigator.

8. Any clinically important illness (apart from T2DM), as judged by the investigator.

11. Positive hepatitis B or hepatitis C virus serology at screening.

12. Positive human immunodeficiency virus test at screening or participant taking antiretroviral medications as determined by medical history or participant's verbal report.

13. At screening blood tests, any of the following:

• AST ≥ 1.5 × ULN

• ALT ≥ 1.5 × ULN

• TBL ≥ 1.5 × ULN (with the exception of Gilbert's syndrome)

• Haemoglobin below the lower limit of the normal range or any other clinically significant haematological abnormality as judged by the investigator.

14. Impaired renal function defined as estimated glomerular filtration rate (eGFR)

≤ 60 mL/minute/1.73m2 as defined by Chronic Kidney Disease Epidemiology Collaboration (2021).

15. Any clinically important abnormalities in clinical chemistry, haematology, coagulation, or urinalysis results other than those specifically described as exclusion criteria herein, as judged by the investigator.

16. Significant late diabetic complications (macroangiopathy with symptoms of congestive heart disease or peripheral arterial disease, microangiopathy with symptoms of neuropathy, gastroparesis, retinopathy requiring treatment, nephropathy) detected in laboratory results or in clinical history/documentation as judged by the investigator.

17. Abnormal vital signs, after 10 minutes of supine rest, defined as any of the following:

• Systolic BP < 90 mmHg or ≥ 150 mmHg

• Diastolic BP < 50 mmHg or ≥ 90 mmHg

• HR < 50 or > 85 bpm at resting state

• Participants may be re-tested for the vital signs criteria only once if, in the investigator's judgement, they are not representative of the participant.

18. Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG and any abnormalities in the 12-lead ECG that, as considered by the investigator, may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology or left ventricular hypertrophy.
