Brief Summary

The study is a prospective, randomized, 52-week double-blind, placebo-controlled, multicenter trial in subjects with T1D followed by a 2-year safety follow-up.

Detailed Description

The SUNRISE study is a prospective, multi-center, double-blind, randomized, placebo-controlled trial in subjects aged 12.0 to <41.0 years diagnosed with T1D, as defined by American Diabetes Association (ADA) criteria, and within 5 years of diagnosis. Time of diagnosis is defined as the first day of insulin administration. Subjects will be stratified by duration (zero up to 1 year and 1 year up to five years) to ensure balance of disease duration across treatment and placebo groups in each strata. For analytical purposes, all subjects12-<41 will be considered cohort A, subjects aged 12-<18 will considered cohort B and subjects aged 18-<41 will be considered cohort C. For subjects aged 12-<18 (Cohort B), dosing will be staggered with an initial 6 subjects aged 14-<18 being enrolled with the last subject a having a minimum of 2 injections with at least 1 week follow-up after the 2nd injection. Safety data from this cohort will be evaluated before opening the study to subjects 12 and older. Subjects should be randomized no sooner than 6 weeks after diagnosis, unless glycemic range is adequately controlled as confirmed by time in glycemic range (70-180 mg/dL) >55% by CGM recording over 3 or more consecutive or non-consecutive days. Screening assessments will include a physical examination, a fundoscopic photograph, chemistry and hematology safety labs, urinalysis, 24-hour urine protein and creatinine, HbA1c, presence of T1D antibodies, and a 4-hour MMTT. Approximately 99 qualified subjects who meet all selection criteria will be randomized in a 2:1 ratio to treatment with TOL-3021 or placebo and treated for 52 weeks. Study drug treatments will be administered via an IM injection into a large muscle every week for 52 weeks. Continuous glucose monitoring (CGM) will be initiated within 5 days prior to the screening MMTT visit and continued through Week 52. Subjects will agree to diabetes management during the study with the goal of maintaining HbA1c levels of approximately 7.0% without frequent episodes of hypoglycemia.

Eligibility Criteria

Inclusion Criteria

1. Diagnosis of Type 1 Diabetes Mellitus based on American Diabetes Association (ADA) criteria and within 5.0 years from diagnosis, defined as the first day of insulin administration.

2. Age at randomization of 12.0 - <41.0 years of age .

3. Adequate glycemic control as defined by HbA1c ≤7.9% based on point-of-care or local lab measurement and time in glycemic range (70-180 mg/dL) >55% by CGM recording over 3 or more consecutive or non-consecutive days within 5 days prior to baseline mixed meal tolerance test (MMTT).

4. On insulin therapy (total insulin dose >0.125 U/kg BW)

5. Presence of antibodies to at least one of the following antigens: GAD65, IA-2, ZnT8, or insulin if obtained within 10 days of the onset of exogenous insulin therapy, or documentation of positive antibodies. In the absence of a positive result for one of the specified antibodies, diagnosis of T1D as per the ADA guidelines..

6. Peak C-peptide during screening 4-hour mixed meal tolerance test (MMTT) ≥ 0.150 nmol/L.

7. Willingness to wear the Dexcom G6 continuous glucose monitoring (CGM) device and use according to instructions including recording of total daily insulin dose taken most of each day from screening to end of treatment period.

8. Written informed consent and, for subjects aged 12-<18 years of age, patient assent and parental or guardian consent, including authorization to release health information.

9. Willingness and ability of subject to comply with all study procedures of the study protocol, including attending all clinic visits.

Exclusion Criteria

1. Receiving a dose of acetaminophen >4,000 mg per day.

2. Body Mass Index (BMI) >32 kg/m² for patients 18 and older (>85th percentile for ages 12-17)

3. Previous immunotherapy for T1D within 2 years of enrollment.

4. Diagnosis of liver disease or hepatic enzymes, as defined by ALT and/or AST ≥ 2.5 times the upper limit of normal (ULN).

5. Hematology: white blood cells (WBC) <3 x 10⁹/L; platelets <100 x 10⁹/L; hemoglobin <10.0 g/dL. (Low WBC values may be repeated every 3-7 days, and results to be discussed with the Medical Monitor.) Any underlying conditions likely to impact red blood cell turnover.

6. Latent autoimmune diabetes of adults (LADA), which is generally associated with preceding history and treatment of T2D with medications typically used for treatment of T2D for more than 30 days.

7. Monogenic diabetes (MODY).

8. Estimated glomerular filtration rate (eGFR) <60 ml/min for ages 18-<41, and <75 ml/min per 1.73 m² for ages 12-<18.
