Criteria

Inclusion Criteria:

1. Capacity to consent; participants or their parents/legal guardians or responsible representatives must be willing and able to give signed informed consent. Participants without capacity must provide assent where applicable.

2. Diagnosis of Type 1 Diabetes, defined by American Diabetes Association Criteria, for at least 12 months.

3. Sex: Male and Female.

4. Age: 12 years to <19 years.

5. HbA1c: 7.0-10 % at time of screening. Participants with a higher HbA1c (10-11%) may be considered, based upon investigator discretion, if patient is adherent with study safety criteria, including a good understanding of diabetes management, regular and consistent blood glucose monitoring, appropriate ketone testing and DKA symptom recognition, appropriate adjustment of insulin doses for meals and activity as well as illness.

6. On Insulin Therapy: Daily injections, to include TID (three times a day), multiple daily dose insulin injection (MDI, > 3 injections daily) or Pump (CSII).

7. A minimum total daily dose (TDD) of insulin ≥0.6 Units/kilogram/day.

8. Females of child bearing potential must be willing to use medically acceptable contraception for the duration of the study and at least one week plus 30 days (one menstrual cycle) post last dose of study drug.

Exclusion Criteria:

1. Pregnancy (positive serum or urine pregnancy test) or breastfeeding.

2. Allergies to any member of SGLT2i class of medications.

3. Type 2 diabetes, Maturity onset Diabetes of Young (MODY) as defined by American Diabetes Association Criteria or pancreatic disorders with resultant impaired pancreatic function.

4. Body Mass Index > 98th percentile by age and sex.

5. Presence of severe hypoglycemic event requiring assistance or glucagon rescue medication within 30 days of screening visit.

6. Presence of documented Diabetic Ketoacidosis (DKA) within 90 days of screening visit.

7. Current and/or anticipated adoption of a carbohydrate-restrictive diet

8. Current eating disorder or weight loss >10% of body weight within 90 days of screening visit.

9. Current and or/anticipated systemic corticosteroid therapy for greater than 5 days (not including inhaled, topical, eye or ear drops containing corticosteroids).

10. Current or history of alcohol, drug or substance abuse.

11. Participation in another drug intervention study within the past 30 days.

12. Presence of a clinically untreated or unstable medical condition (including diagnosed Hypertension, SBP>95%) or laboratory finding that may interfere with any aspect of the study.

13. Any concomitant medication known to interfere with the investigational product and/or renal function and/or planned study assessments based on investigators' judgement.

14. Unable to adhere with study safety criteria, in the investigator's opinion, including a suboptimal understanding of diabetes management that would include regular and consistent blood glucose monitoring, appropriate ketone testing and DKA symptom recognition, appropriate adjustment of insulin doses for meals and activity as well as illness

15. Participants are not allowed to change their insulin administration method (injection to pump or vice versa) throughout the study period, nor change to hybrid or closed loop insulin pumps during the study period.

16. Known Hypersensitivity to Iohexol
