The objective of this clinical trial is to assess whether ladarixin treatment is effective in preserving beta-cell function and delaying the progression of type 1 diabetes (T1D) in adolescent and adult patients. The safety of ladarixin in the specific clinical setting will be also evaluated.

Official Title

Phase 3, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Assess Efficacy - Safety of 400 mg Twice a Day Oral Ladarixin in Pts With New-onset Type 1 Diabetes and Low Residual β-cell Function at Baseline (GLADIATOR STUDY)


This is a phase 3, multicenter, double-blind, placebo-controlled study. It has been designed to further evaluate whether ladarixin is effective in preserving beta-cell function and slowing-down the progression of T1D) in patients with a more severe disease presentation. The study is planned to be performed at about 40 study centers in EU, US and in other countries, if appropriated. At each study center, the Principal Investigator (PI) will be responsible for ensuring that the investigation is conducted according to the signed Investigator agreement, the protocol, GCP guidelines, and local regulations. The study is planned to involve -327 patients with new-onset T1D, to include about 200 adolescents (14-17 years). Patients will be randomly (2:1) assigned to receive either ladarixin treatment (400 mg b.i.d. for 13 cycles of 14 days on/14 days off - treatment group) or matched placebo (control group). The two groups will be balanced within centers.
