Sotagliflozin to Slow Kidney Function Decline in Persons with Type 1 Diabetes and Diabetic Kidney Disease
Recruiting
I'm InterestedTrial ID: NCT06217302
Purpose
Powerful new drugs that can prevent or delay end stage kidney disease (ESKD) - so called sodium-glucose cotransporter-2 inhibitors (SGLT2i) - are now available for patients with type 2 diabetes. Whether these drugs have similar effects in patients with type 1 diabetes (T1D) remains unknown because of the few studies in this population, due to concerns about the increase in risk of diabetic ketoacidosis (DKA, a serious, potentially fatal acute complication of diabetes due to the accumulation of substances called ketone bodies) observed with SGLT2i therapy in T1D. One of the few T1D studies conducted to date showed that implementing an enhanced DKA prevention plan can reduce the risk of DKA associated with the SGLT2i sotagliflozin (SOTA) to very low levels. In the present study, a similar DKA prevention program will be used to carry-out a 3-year trial to test the kidney benefit of SOTA in 150 persons with T1D and moderate to advanced DKD. After a 2-month period, during which diabetes care will be standardized and education on monitoring and minimizing DKA implemented, eligible study subjects will be randomly assigned (50/50) to take one tablet of SOTA (200 mg) or a similarly looking inactive tablet (placebo) every day for 3 years followed by 2-months without treatment. Neither the participants nor the study staff will know whether a person was assigned to taking SOTA or the inactive tablet. Kidney function at the end of the study will be compared between the two treatment groups to see whether SOTA prevented kidney function loss in those treated with this drug as compared to those who took the inactive tablet. The DKA prevention program will include participant education, close follow-up with study staff, continuous glucose monitoring, and systematic ketone body self-monitoring with a meter provided by the study. If successful, this study will provide efficacy and safety data that could be used to seek FDA approval of SOTA for the prevention of kidney function decline in patients with T1D and DKD.

* Use of non-FDA approved automated insulin delivery devices;
* Use of any SGLT inhibitor in the previous 2 months;
* Use of dual medication RASB therapy (spironolactone, eplerenone, finerenone are allowed in combination with RASB therapy);
* Use of glucagon-like peptide (GLP-1) receptor agonists and other non-insulin glucose lowering agents if in use for less than 3 months and/or not on stable dose at screening;
* Use of anti tumor necrosis factor (TNF) alpha biologic medications at screening;
* Known allergies, hypersensitivity, or intolerance to SOTA;
* History of ≥3 severe hypoglycemic events (requiring third-party assistance for correction) within 3 months of screening;
* History of diabetic ketoacidosis (DKA) or non-ketotic hyperosmolar state within 3 months of screening OR \>1 episode of DKA or non-ketotic hyperosmolar state within 12 months of screening;
* Blood beta-hydroxybutyrate (BHB) \>0.6 mmol/L for \>2 hours on \>2 occasions during the Run-in period;
* Inadequate beta hydroxybutyrate (BHB) testing (\<50% of the prescribed measurements) during Run-in;
* History of primary renal glycosuria;
* History of biopsy-proven non-diabetic chronic kidney disease (CKD);
* History of kidney transplant or currently on chronic dialysis;
* Current or past history of decompensated cirrhosis (defined as variceal bleeding, ascites or hepatic encephalopathy), and/or known diagnosis of cirrhosis based on liver biopsy, imaging, or elastography, and/or aspartate aminotransferase (AST) or alanine transaminase (ALT) at screening \>2 times upper limit of normal, and/or total bilirubin at screening \>1.3 times upper limit of normal).
* History of severe acquired immune deficiency syndrome or human immunodeficiency virus (HIV) infection or severely immunocompromised status;
* Cancer treatment (excluding non-melanoma skin cancer treated by excision, carcinoma in situ of the cervix or uterus, ductal breast cancer in situ, resected non-metastatic breast or prostate cancer) within one year of screening.
* Illicit drug abuse within 6 months of screening;
* Heavy alcohol use (for men, 5 drinks or more on any day or 15 drinks or more per week; for women, 4 drinks or more on any day or 8 drinks or more per week);
* Participation in another interventional clinical research study within 30 days of screening;
* Breastfeeding, pregnancy, or unwillingness to be on contraception during the trial;
* Systolic blood pressure \>155 mmHg or diastolic blood pressure \>95 mmHg at screening;
* Presence of a clinically significant medical history, physical examination, or laboratory finding that may interfere with any aspect of study conduct or interpretation of results;
* Any condition that may render the patient unable to comply with study requirements and/or complete the study.
