Study summary

Objectives Primary study objective: To determine whether orally-administered ladarixin versus placebo adjunctive therapy improves insulin sensitivity in overweight, insulin-resistant (IR) type 1 Diabetic (T1D) adult subjects.

Secondary study objectives: To determine whether orally-administered ladarixin versus placebo adjunctive therapy is safe and well-tolerated in overweight, IR T1D adult subjects.

Read the detailed description

This study is a randomized, placebo-controlled, double-blinded, 2-arm, 2-period crossover phase II trial using the CXCR1/CXCR2 chemokine receptor antagonist ladarixin versus placebo as adjunctive therapy to insulin to improve insulin sensitivity as well as glucometabolic outcomes in adult, insulin-requiring, overweight, IR T1D patients.

This trial will randomize 38 male and female patients 21-65 years of age, inclusive, with established insulinrequiring T1D and IR. After a 2:1 randomization into a treatment sequence (either ladarixin followed by placebo, or placebo followed by ladarixin, respectively), patients will be followed up for a maximum of 53 weeks.

The study database will be locked when the last patient randomized has completed visit 9 (week 52/53) and data have been cleaned.

  5. HbA1c between 7.5%-10.0%, inclusive, as per results of screening laboratory measurement;
  6. evidence of IR based on a total daily insulin dose >0.8 U/kg/ day and/or a screening estimated glucose disposal rate (eGDR) \< 9 mg/kg/min 1-3 value strongly indicative of IR, sex- and ageadjusted;
  7. subject is overweight or obese with a BMI of between 25-40 kg/m2, inclusive;

  2. use of non-insulin medications for adjunctive blood glucose control (e.g: antidiabetic agents such as metformin, sulfonylureas, glinides, thiazolidinediones, exenatide, liraglutide, DPP-IV inhibitors, SGLT-2 inhibitors or amylin);
  3. use of medications for weight reduction (such as: Belviq (lorcaserin), Qsymia (Phentermine + topiramate), Orlistat (xenical));
  4. use of a medication such as stimulants, antidepressants and/or psychotropic agents that could affect weight gain or glycemic control of T1D;
  5. subject is on treatment with drugs metabolized by CYP2C9 with a narrow therapeutic index [i.e., phenytoin, warfarin, and high dose of amitriptyline (>50 mg/day)];
  6. any medications known to influence glucose tolerance (e.g. beta-blockers, angiotensin-converting enzyme inhibitors, interferons, quinidine antimalarial drugs, lithium, niacin, etc.);
  7. evidence of cardiac QTcF > 470 msec and/or any history of significant cardiovascular disease/abnormality;
  8. any condition, including unstable dietary approach and disordered eating behaviour patterns, that in the judgment of the investigator will adversely affect patient's safety or the completion of the protocol or otherwise confound study outcome;
  9. pregnancy (females) based on serum test (quantitative beta hCG) at screening; unwillingness to use effective contraceptive measures up to 2 months following trial discharge (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).
  10. clinical diagnosis of celiac disease that is in poor control as defined by most recent tissue transglutaminase (tTG) that is in the abnormal range;
  11. history of ≥1 Diabetic Ketoacidosis (DKA) events in the past 6 months;
  12. history of ≥1 severe hypoglycemic events (cognitive impairment that required assistance to treat) in the past 6 months;
  13. hypoalbuminemia defined as serum albumin \< 3 g/dL ;
  14. 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];
  15. moderate to severe renal impairment calculated by estimated Glomerular Filtration Rate (eGFR) \<60 mL/min/1.73 m2 as determined using Chronic Kidney Disease Epidemiology Collaboration (CKDEPI) creatinine equation;
  16. poor accessibility to veins for blood collection;
  17. past (within 1 month prior to randomization) or current administration of any immunosuppressive medications (including oral, inhaled or systemically injected steroids) and use of any investigational agents, including any agents that impact the immune response or the cytokine system;
  18. condition which interferes with the ability to accurately determine glycated HbA1c. Examples include: Genetic variants (e.g. HbS trait, HbC trait), elevated fetal hemoglobin (HbF) and chemically modified derivatives of hemoglobin (e.g. carbamylated Hb in patients with renal failure); Any condition that shortens erythrocyte survival or decreases mean erythrocyte age (e.g., recovery from acute blood loss, hemolytic anemia); Iron deficiency anemia, iron replacement therapy;
  19. significant systemic infection during the 4 weeks before the first dose of study drug (e.g., infection requiring hospitalization, major surgery, or i.v. antibiotics to resolve; other infections, e.g., bronchitis, sinusitis, localized cellulitis, candidiasis, or urinary tract infections, must be assessed on a case-bycase basis by the investigator regarding whether they are serious enough to warrant exclusion).

What researchers measure

Primary outcomes

  1. The mean difference in glucose infusion rate (GIR) from baseline

    The glucose infusion rate (GIR) is a measure of the rate at which the patient receives intravenous administration of dextrose, which increases blood sugar levels. GIR is expressed in mg per kilogram body weight per minute (mg/Kg/min).

    Time frame: Week 25 of each treatment period (visits 4 and 8)

Secondary outcomes

  1. Change from baseline of HbA1c levels

    In this study glycated hemoglobin (HbA1c) must be between 7.5%-10.0%, inclusive, as per results of screening laboratory measurement.

    Time frame: Week 25/26 (no later than 10 days after the last IMP dose) of each treatment period (visits 5 and 9)

  2. Change in average (previous 3 days) daily insulin requirements

    In this study insulin requirement is calculated as IU/kg/day averaged over the previous 3 days.

    Time frame: Week 25/26 (no later than 10 days after the last IMP dose) of each treatment period (visits 5 and 9)
