NCT02384889

Brief Summary

This study is a multicenter, double-blind, placebo-controlled, 2:1 randomly assigned, phase 1 clinical trial for individuals with type 1 diabetes. It is a blinded dose-ranging study enrolling patients with new onset type 1 diabetes with documented continued residual C-peptide production. After a 4 week screening and run-in period during which eligibility will be determined and glycemic control optimized, subjects will have a 3-month double-masked treatment period with either DFMO or placebo. After a 3 month wash-out period the durability of effect will be assessed. Subjects will be randomly assigned (6 to DFMO; 3 to placebo in each cohort) to 1 of 4 sequential dose cohorts.

Eligibility Criteria

Age12 Years - 40 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Males and females 12-40 years of age with a clinical diagnosis of T1D within 2 - 8 months after diagnosis at the time of visit 2.
  • Random non-fasting C-peptide level of \>0.2 pmol/mL at visit 1.
  • Positive for any one of the following diabetes-related autoantibodies (mIAA, GADA, IA-2A, or ZnT8A)
  • Treatment naïve of any immunomodulatory agent
  • Normal hearing at screening, defined as acceptable results of pure-tone audiometry (\<20 decibel \[dB\] baseline thresholds for frequencies 250, 500, 1000, and 2000 Hz

You may not qualify if:

  • Presence of severe, active disease that interferes with dietary intake or requires the use of chronic medication, with the exception of well-controlled hypothyroidism and mild asthma not requiring oral steroids. Presence of any psychiatric disorder that will affect ability to participate in study.
  • Diabetes other than T1D
  • Chronic illness known to affect glucose metabolism (e.g. Cushing syndrome, polycystic ovarian disorder, cystic fibrosis) or taking medications that affect glucose metabolism (e.g. steroids, metformin)
  • Inability to swallow pills
  • Psychiatric impairment or current use of anti-psychotic medication
  • Any condition that, in the investigator's opinion, may compromise study participation or may confound the interpretation of the study results.
  • Hematologic abnormalities at screening (anemia, leukopenia (particularly neutropenia), or thrombocytopenia)
  • Impaired renal function (assessed by history and BUN/Creatinine, DFMO is renally excreted)
  • Female participants of child-bearing age must not be pregnant and agree to use an effective form of birth control or be abstinent during the study period.
  • BMI \>95% for age and sex
