Clinical Trial Summary

This is an investigator-initiated, randomized controlled trial in adult KTRs (N=50) with stable allograft function to assess: 1) the reversibility of the expected acute changes in eGFR with sotagliflozin (donated by Lexicon); 2) proportion of patients completing the protocol according to different eGFR reporting strategies (using a predefined algorithm to manage the expected pharmacological effect of sotagliflozin on eGFR); 3) safety and tolerability of sotagliflozin.

• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Adults =18 years
• Recipients of kidney transplant with stable eGFR*
• eGFR-creatinine (CKD-EPI 2021) =25 mL/min/1.73 m2
• Informed consent
• Stable eGFR will be ascertained by careful chart review establishing that the patient's current graft has been functioning for at least 12 months post-transplantation, patients have not been treated for acute rejection within the prior 3 months, and a creatinine-based eGFR is stable (two consecutive measurements separated by at least 28 days within 5 mL/min/1.73 m2) and =25 mL/min/1.73 m2.

Exclusion Criteria:

• Recurrent urinary tract infections (>2 episodes/year or antibiotic prophylaxis)
• Biopsy-proven acute rejection within 12 weeks
• Screening serum potassium >5.5 mmol/L
• Uncontrolled hypertension (systolic blood pressure >180/100 mmHg)
• New York Heart Association (NYHA) Class IV HF
• Myocardial infarction, unstable angina, revascularization procedure (e.g., stent or bypass graft surgery), or cerebrovascular accident within 12 weeks
• History of diabetic ketoacidosis
• Type 1 Diabetes Mellitus
• Hereditary glucose-galactose malabsorption or primary renal glucosuria
• Liver disease (e.g., acute hepatitis, chronic active hepatitis, cirrhosis); Alanine aminotransferase (ALT) levels >2.0 times the upper limit of normal (ULN) or total bilirubin >1.5 times the ULN, unless consistent with Gilbert's disease
• Malignancy within 5 years (exceptions: squamous and basal cell carcinomas of the skin and carcinoma of the cervix in situ, or a malignancy that in the opinion of the investigator is considered cured with minimal risk of recurrence)
• Human immunodeficiency virus antibody positive
• Major surgery within 12 weeks
• Atraumatic amputation within past 12 months of screening, or an active skin ulcer, osteomyelitis, gangrene, or critical ischemia of the lower extremity within 6 months of screening
• Combination use of ACEi and ARB
• Current use of an SGLT2 inhibitor (within 12 weeks prior to randomization)
• Known allergies, hypersensitivity, or intolerance to SGLT2i or its excipients
• Digoxin plasma level >1.2 ng/mL
• Clofibrate, fenofibrate, dronedarone, or ranolazine treatment that has not been at a stable dose in the 30 days prior to screening or randomization, or a dose adjustment is expected
• Received an active investigational drug (including vaccines) other than a placebo agent, or used an investigational medical device within 12 weeks before Day 1/baseline
• Pregnant or breast-feeding or planning to become pregnant or breast-feed during the study
• Women of childbearing potential not willing to use a highly-effective method(s) of birth control, or who are unwilling or unable to be tested for pregnancy
• Any condition that in the opinion of the investigator would make participation not in the best interest of the subject

Intervention

Diagnostic Test:
• eGFR reporting
To test the proportion of patients successfully completing the protocol according to different eGFR reporting strategies, randomization in a 1:1 fashion at the patient level (n=50) will occur as follows: only study-related eGFR values >25% below baseline will be reported to patients and providers all study-related eGFR will be provided to patients and providers

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Safety Assessments	- Acute changes in eGFR (baseline to 4 weeks)	4 weeks
Other	Safety Assessments	- Longer-term changes in eGFR (baseline to 12 weeks and 4 weeks to 12 weeks)	12 weeks
Other	Safety Assessments	- Reversibility of changes in eGFR (12 to 16 weeks - after drug discontinuation)	Weeks 12-16 (off-drug)
Other	Safety Assessments	- Acute Kidney Injury (>50% increase in serum creatinine/40% decline in eGFR within one week), which will be assessed throughout the on-drug period of 12 weeks	12 weeks
Other	Safety Assessments	- All adverse events (AEs)	12 weeks
Other	Safety Assessments	- All serious adverse events (SAEs)	12 weeks
Other	Safety Assessments	- Diarrhea	12 weeks
Other	Safety Assessments	- Infection requiring treatment with anti-microbials (including urogenital infection and urinary tract infections)	12 weeks
Other	Safety Assessments	- Severe hypoglycemia (event that requires assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions)	12 weeks
Other	Safety Assessments	- Diabetic ketoacidosis	12 weeks
Other	Safety Assessments	- Hyperkalemia (>5.5 mmol/L)	12 weeks
Other	Safety Assessments	- Hypotension (symptomatic SBP <90 mmHg or hypotension requiring adjustment in blood pressure medications or treatment in an emergency or hospitalized setting)	12 weeks
Other	Tolerability Assessments	- Proportion of participants able to complete the full 12 weeks of treatment, according to randomized arm	12 weeks
Other	Tolerability Assessments	- Study medication discontinuation rates	12 weeks
Other	Tolerability Assessments	- KDQOL-36 questionnaire	12 weeks
Primary	Reversibility of eGFR changes	Following 12 weeks of open-label drug treatment, participants will stop drug and be followed for a further four weeks (16 weeks total). Reversibility will be assessed as the proportion of patients who return to baseline eGFR (+/- 10%) by the end of the 4-week off-treatment period.	16 weeks total
Secondary	Proportion of patients successfully completing the full treatment protocol, according to randomized groups	Following 12 weeks of open-label drug treatment, participants will stop drug and be followed for a further four weeks. The proportion of patients completing the full 16 weeks will be compared according to randomized groups.	16 weeks total
