Panbela Therapeutics, Inc. announced that it has commenced a Phase II double-blind, randomized study to evaluate CPP-1X-T (Eflornithine tablets) for recent onset type 1 diabetes, in collaboration with Indiana University School of Medicine and funded by JDRF, the leading global type 1 diabetes research and advocacy organization. Indiana University expects to enroll 70 patients in the Phase II clinical trial at approximately 6 centers in the United States. Study eligibility will be for patients with recent onset type 1 diabetes.

Participants will be randomized 2:1 to CPP-1X-T, administered orally with food, twice daily, at a 1000 mg/m2 dose, or placebo over 6 months followed by a 6 month wash out period to assess durability of response. The primary objective will be to determine the difference between the treated and placebo 2-hour Area Under the Curve (AUC)-mean using the log (mean C-peptide+1) at the 6-month end of treatment period. Secondary objectives will include C-peptide AUC, fasting and stimulated proinsulin/c-peptide ratios a biomarker of ß cell stress, and the urine polyamine content at 3, 9, and 12 months timepoints.
