A Phase 2 interventional study of Sotagliflozin initiation in Type 1 Diabetes Mellitus, Chronic Kidney Disease (CKD) With Diabetes Mellitus (DM) and Chronic Kidney Disease, sponsored by HealthPartners Institute. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-10-23.

The goal of this clinical trial is to develop and evaluate a novel diabetes ketoacidosis risk mitigation strategy to support the safe use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) therapy in participants with type 1 diabetes (T1D) and mild to moderate chronic kidney disease (CKD). The main objectives of this study are to:
Participants will be asked to:
Sodium-glucose cotransporter 2 (SGLT2) inhibitors and similar medications can prevent progression of heart and kidney disease but strategies to safely use these medications in people with type 1 diabetes (T1D) have not yet been developed. We will conduct an open-label trial of sotagliflozin (an SGLT 1/2 inhibitor) in 80 people with T1D with no chronic kidney disease (CKD), moderate risk CKD and high or very high risk CKD. Through the use of continuous ketone monitoring, we will characterize ketone levels in both individuals with chronic kidney disease (CKD) and T1D, compared to those with T1D without CKD, before and after starting sotagliflozin. We will improve our understanding of the risk factors for developing elevated ketone levels and optimize prevention of diabetes ketoacidosis through the development and refinement of an enhanced combined continuous glucose and ketone monitoring data visualization report.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

In this single arm trial, all patients will be started on sotagliflozin at a dose of 200mg/d. After 3 months of sotagliflozin 200 mg/d, patients who do not achieve good glycemic control (TIR \>60%) and who have moderate or no CKD (eGFR \>60) will be offered the option to increase sotagliflozin to 400mg/d. All other participants will continue taking 200 mg sotagliflozin daily.
Drug: Sotagliflozin initiation
All patients will be started on sotagliflozin at a dose of 200mg/d. After 3 months of sotagliflozin 200 mg/d, patients who do not achieve good glycemic control (TIR \>60%) and who have moderate or no CKD (eGFR \>60) will be offered the option to increase sotagliflozin to 400mg/d. The decision to increase sotagliflozin dose will be a shared decision between the study subject and the study investigators. All other participants will continue taking 200 mg sotagliflozin daily. After completing all study visits, all participants will stop taking sotagliflozin and continue care with their healthcare provider(s).

Start is estimated for Jan 2027; primary completion for Feb 2029, 25 months later.
Of 83 non-industry phase 2 interventional studies under Diabetes Mellitus, Type 1, half reached primary completion within 51 months of starting (the median), counting those still running; a quarter within 31 and three quarters within 76. This study's planned 25 months is below that.
Counting every sponsor, half of 133 studies reached it within 36 months; a quarter within 17 and three quarters within 63.
Start moved once since we started tracking on Sep 25, 2026: Sep 2026 → Jan 2027, on Oct 23, 2026.
