9. Normal renal function with eGFR ≥ 90 mL/min at Screening

10. Must match to the pooled mean age (± 10 years), BMI (within 20%) and gender (ratio should be similar) of mild, moderate, and severe (if applicable) renal impaired subjects at Screening.

    Subjects with Mild, Moderate, and Severe Renal Impaired Function (Groups 1, 2, and 3):

11. Considered clinically stable in the opinion of an Investigator

12. Presence of mild renal impairment (eGFR ≥ 60 and <90 mL/min), moderate renal impairment (eGFR ≥ 30 and <60 mL/min), or severe renal impairment (eGFR <30 mL/min) or kidney failure not receiving dialysis, at Screening: renal impairment should have been stable for at least 1 month prior to Screening.

Exclusion Criteria (All Participants)

1. Female who is lactating or breastfeeding

2. Female who is pregnant according to the pregnancy test at Screening or prior to study drug administration or planning to become pregnant before 90 days after the last study drug administration.

3. History of significant hypersensitivity to MBX 2109 or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.

4. History of, or positive test for hepatitis B surface antigen (HbsAg), hepatitis C antibody (HCV Ab), or HIV antibody, at Screening.

5. Presence or history of any disorder that could interfere with completion of the study based on the opinion of an Investigator.

6. Intake of MBX 2109, or any investigational product (IP) in the 28 days prior to study drug administration.

7. Have urinary incontinence without catheterization

8. Receipt of blood products within 3 months prior to study drug administration.

9. Donation of 50 mL or more of blood in the 28 days prior to study drug administration

10. Donated 500 mL or more of blood within 56 days prior to study drug administration

11. Donated plasma within 2 weeks prior to Screening or donated platelets within 6 weeks prior to Screening.

12. Immunization with a Coronavirus Disease 2019 (COVID-19) vaccine in the 14 days prior to the first study drug administration.

13. Scheduled immunization with a COVID-19 vaccine during the study that, in the opinion of an Investigator, could potentially interfere with subject participation, subject safety, study results, or any other reason.

14. Use of St. John's wort in the 28 days prior to the first study drug administration.

15. Inclusion in a previous group for this clinical study

16. Any skin condition and/or tattoo that may interfere with the injection site evaluation.

    Subjects with Normal Renal Function (Group 4):

17. Presence of significant gastrointestinal, liver, or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism, or excretion of drugs or known to potentiate or predispose to undesired effects.

18. History of significant gastrointestinal, liver, or kidney disease that may affect drug bioavailability.

19. Presence of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic, or dermatologic disease.

20. Presence of clinically significant ECG abnormalities at the Screening visit, as defined by medical judgment.

21. Positive test result for alcohol and/or drugs of abuse at Screening or prior to the first study drug administration.

22. Supine or semi-supine blood pressure below 90/50 mmHg at the Screening visit

23. Supine or semi-supine blood pressure higher than 140/90 mmHg at the Screening visit (blood pressure readings greater than 140/90 mmHg may be retested if completed thought to be influenced by stress, at the discretion of the Investigator).

24. Supine or semi-supine pulse rate less than 40 beats per minute (bpm) or more than 100 bpm at Screening.

25. Any clinically significant illness in the 28 days before Day 1 of the study

26. Use of any prescription drugs (with the exception of hormonal contraceptives or hormone replacement therapy) in the 28 days before Day 1 of the study.

27. Use of over-the-counter (OTC) drugs and natural health products (eg, herbal remedies) at least 7 days (or 5-times the half-life of the drug, if longer) prior to study drug administration.

28. Use of any enzyme-modifying drugs, or drugs with effects on membrane transporters, including any strong cytochrome P450 3A4 and P-glycoprotein inducers and inhibitors in the previous 28 days before Day 1 of the study.

    Subjects with Mild, Moderate, and Severe Renal Impaired Function (Groups 1, 2, and 3):

29. History of renal transplant

30. Supine or semi-supine blood pressure below 90/50 mmHg at the Screening visit.

31. Supine or semi-supine blood pressure higher than 180/110 mmHg at the Screening visit.

35. Presence of clinically significant physical examination, laboratory test, or ECG finding that, in the opinion of an Investigator and/or Sponsor, may interfere with any aspect of study conduct or interpretation of results.

36. Subjects requiring treatment for renal impairment or other chronic disease (eg, well controlled diabetes, hypertension) must be on a stable treatment plan (medicines, doses, and regimens) for at least 14 days (except insulin) prior to study drug administration and during the entire study.

37. Positive Screening of alcohol and/or drugs of abuse at Screening or prior to study drug administration unless results can be explained by a prescription medication.
