• Accepted abstract to include results from phase 2 proof of concept trial on the potential for CXCR1/2 inhibition to slow-down the progression of new-onset T1D
• Trial objective was to investigate whether ladarixin, an orally available investigational small molecule drug, has sufficient activity to preserve β-cell function in new-onset T1D

MILAN and SAN MATEO, Calif., May 18, 2020. – Dompé Farmaceutici S.p.A and Dompé U.S. Inc., (collectively Dompé) announced today that the Company will present new data at the American Diabetes Association's 80th Scientific Sessions in Chicago, IL, June 12-16, 2020. The abstract will highlight clinical data from Dompé’s recently completed Phase II clinical trial (MEX0114) for its novel CXCR1/2 inhibitor, ladarixin, in new-onset T1D.1[Oral Presentation: 249-OR]A Randomized, Double-blind Phase 2 Trial of The CXCR1/2 Inhibitor Ladarixin In Adult Patients with New Onset Type 1 DiabetesPresenter: Prof. Paolo Pozzilli, MDSunday, June 14, 2020 5:00 PM – 5:15 PM CDTFor media queries or to schedule an interview, please contact Randi Kahn or Stefano Amoroso/Guido Romeo (contact information below).About Type 1 Diabetes (T1D)T1D is a chronic autoimmune disease that, over time, results in an immune-mediated loss of functional pancreatic β-cell mass, leading to symptomatic diabetes and lifelong insulin dependence.2,3 Currently available treatment approaches focus on glycemic control and do not address the high unmet medical need of delaying disease progression by preserving β-cell function.4CXCL-8, a pro-inflammatory chemokine also known as IL-8, is an important mediator in several immune and metabolic disorders, including T1D.5 Modulation or inhibition of CXCL-8 activity through blockade of its cellular receptors, CXCR1/2, may be considered a target for the development of innovative treatments aimed at slowing the progression of T1D.6About MEX0114MEX0114 was a phase 2, multicenter, randomized, double-blind, placebo-controlled study in adult patients with new-onset type 1 diabetes. The objective of this clinical trial was to investigate whether ladarixin, a non-competitive allosteric inhibitor of CXCR1/2, has sufficient activity to preserve β-cell function and slow-down the progression of new-onset T1D. T1D was considered “new-onset” if the patient had received their first insulin administration within the past 100 days of randomization into the trial.1The primary endpoint was the 2-hour AUC of C-peptide response to the mixed meal tolerance test (a standard measure of endogenous insulin secretion in T1D7) after three cycles of oral ladarixin treatment administered over 12 weeks. The safety of ladarixin as well as prespecified secondary analyses for A1c and total daily insulin requirement were also evaluated.1About Dompé
