JAK1 Inhibitor Ivarmacitinib for Improving Pancreatic Islet Function in T1D (INSPIRE-T1D)
INhibiting JAK1 to Save Pancreatic Islet Function in Recently Established T1D(INSPIRE-T1D)
This is a double-blind, randomized, placebo-parallel-controlled, multicenter study. The objective is to evaluate the efficacy and safety of Ivarmacitinib 8 mg administered for 52 weeks in preserving pancreatic β cell function in subjects with newly-onset type 1 diabetes mellitus. The study consists of a screening period (V1, up to 2 weeks), a 52-week double-blind treatment period (V2 to V14), and a 4-week safety follow-up period (V15).

Beskrivelse
Inclusion Criteria:
- Confirmed diagnosis of type 1 diabetes mellitus.
- Able to complete randomization and initiate treatment with the study drug within 100 days of being formally diagnosed with type 1 diabetes.
- Peak stimulated C-peptide level ≥ 0.2 pmol/mL during the mixed-meal tolerance test performed in the screening period.
- Tested positive for at least one type 1 diabetes-associated autoantibody.
Exclusion Criteria:
- Presence of any autoimmune disease other than type 1 diabetes mellitus, except for stable autoimmune thyroid disease.
- Presence of active infection and/or fever.
- Known current or prior infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV), or serological evidence of such infection at screening.
- Active pulmonary tuberculosis, malignancy, etc.
- Severe hepatic impairment (AST or ALT >3 × upper limit of normal), or severe renal impairment or end-stage renal disease (eGFR < 30 mL/min/1.73 m²).
- Prior exposure to immunomodulatory agents, including baricitinib, ivarmacitinib, IL-1 receptor antagonists, tocilizumab (anti-IL-6 monoclonal antibody), infliximab (anti-TNF-α monoclonal antibody), interferons, etc.
- Severe cardiovascular disease such as angina pectoris, myocardial infarction, or stroke within the previous 6 months.
- Severe gastrointestinal disease.
- Surgical procedure performed within the past 6 months.
- Medical, psychological, or social conditions that, in the opinion of the investigator, may interfere with trial safety or proper completion.
