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 Recent 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.

  2. Moderate to severe renal impairment as per estimated Glomerular Filtration Rate (eGFR) 60 mL/min/1.73m2, as determined using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation (see Appendix 14.4.3);
  3. Hepatic dysfunction defined by increased ALT/AST > 3 x upper limit of normal (ULN) and increased total bilirubin > 3 mg/dL [>51.3 μmol/L];
  4. Hypoalbuminemia defined as serum albumin < 3 g/dL;
  5. QTcF > 470 msec;
  6. Occurrence of an episode of ketoacidosis or hypoglycemic coma in the past 2 weeks;
  7. A history of significant cardiovascular disease/abnormality;
  8. Known hypersensitivity to non-steroidal anti-inflammatory drugs;
  9. Concomitant treatment with drugs metabolized by CYP2C9 with a narrow therapeutic index [i.e. phenytoin, warfarin, sulphanylurea hypoglycemics (e.g. tolbutamide, glipizide, glibenclamide/glyburide, glimepiride, nateglinide) and high dose amitriptyline (> 50 mg/day)];

    10. Previous (past 2 weeks) and concomitant treatment with antidiabetic agents as

    metformin, sulfonylureas, glinides, thiazolidinediones, exenatide, liraglutide, DPP-IV inhibitors, SGLT2-inhibitors or amylin, or any medications known to influence glucose tolerance (e.g. beta-blockers, angiotensin-converting enzyme inhibitors, interferons, quinidine antimalarial drugs, lithium, niacin, etc.);

    11. Past (past month) or current administration of any immunosuppressive medications

    (including oral or systemic corticosteroids) and use of any investigational agents, including any agents that impact the immune response or the cytokine system;

    12. Significant systemic infection during the 4 weeks before the 1st dose of the study

    drug (e.g., infection requiring hospitalization, major surgery, or IV antibiotics to resolve; other infections, e.g., bronchitis, sinusitis, localized cellulitis, candidiasis, or urinary tract infections, must be assessed on a case-by-case basis by the investigator regarding whether they are serious enough to warrant exclusion);

    13. History of positive status for hepatitis A (IgM), hepatitis B (not due to

    immunization), hepatitis C and HIV..

    14. Pregnant or breast-feeding women. Unwillingness to use effective contraceptive

    measures up to 2 months after the end of study drug administration (females and males). Effective contraceptive measures include a hormonal birth control (e.g. oral pills, long term injections, vaginal ring, patch); the intrauterine device (IUD); a double barrier method (e.g. condom or diaphragm plus spermicide foam); abstinence.
