About this trial
This is an interventional treatment trial for Type 1 Diabetes focused on measuring glycemic control, insulin-resistant type 1 diabetes.
Eligibility Criteria
Inclusion Criteria:
- clinical diagnosis of autoimmune T1D as documented by positive T1D-related autoantibodies [the presence of at least one or more of Insulin autoantibodies (IAA), Anti-GAD (GAD65), Anti-IA2 (IA2), Zinc Transporter 8 (ZnT8)];
- age 21-65 years, inclusive, at the time of consent;
- T1D duration > 1 year;
- detectable fasting C-peptide (≥ 0.02 nmol/L) as per the result of screening laboratory measurement;
- current insulin standard of care (ISOC), either established use of an insulin pump (closed loop system excluded) or a stable dose level and dose frequency for the last two months prior to screening, with no plans to switch the modality of insulin administration during the trial;
- routine use of a self-owned Continuous Glucose Monitoring (CGM) system that can record glucose concentrations continuously for at least 7 days;
- HbA1c value >7.5% as per the result of screening laboratory measurement;
- evidence of IR based on a total daily insulin dose >0.8 U/kg/day;
- subject is overweight or obese as per body mass index (BMI) of between 24-33 kg/m2, inclusive;
- ability to comply with all protocol procedures for the duration of the study, including scheduled follow-up visits and examinations, and willing to be contacted by clinical trial staff;
- provision of signed informed consent prior of any study-related procedure not part of standard medical care.
Exclusion Criteria:
- use of a "closed loop system" for integrated glucose reading/insulin infusion;
- known or suspected hypersensitivity to the active pharmaceutical ingredient, non-steroidal anti-inflammatory drugs or any excipient of the investigational medicinal products (e.g. lactose and croscarmellose) as well as patients with congenital lactase deficiency, galactosaemia or glucose-galactose intolerance will have to be excluded;
- 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) within one month of randomization as well as required in the participant's standard of care;

- 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 (CKD-EPI) creatinine equation;
- past (within 1 month prior to screening) or current administration of any immunosuppressive medications (including oral or systemically injected steroids) and use of any investigational agents, including any agents that impact the immune response;
- a condition already known which interferes with the ability to accurately determine glycated HbA1c;
- significant systemic infection during the 4 weeks before the 1st 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-by-case basis by the investigator regarding whether they are serious enough to warrant exclusion).

5. Study Description
Brief Summary
Primary objective: To determine whether oral ladarixin versus placebo adjunctive therapy improves glycemic control in overweight, insulin resistant (IR) adult subjects with type 1 diabetes (T1D).
Secondary objectives: To ascertain the effect of ladarixin on glycemic variability as per CGM derived parameters. To determine the safety of oral ladarixin versus placebo adjunctive therapy in overweight, IR adult subjects with T1D.
Exploratory objectives (if site is able and deems appropriate to accommodate and conduct these objectives): To determine the effects on insulin sensitivity and circulating markers of inflammation (leukocytes and inflammatory cytokines). Glycemic variability by additional CGM parameters. eGDR and BMI assessments.
Detailed Description
This study will be a randomized, placebo-controlled, double-blinded, 2- parallel arm, phase II trial. It will enroll up to 86 patients across all genders, 21-65 years, inclusive, with established insulin-requiring T1D and IR, assigned (1:1) to receive either oral ladarixin 400 mg b.i.d. for 7 cycles (26 weeks) of 14 days on/14 days off (treatment group) or matched placebo (control group). Patients will be involved in the trial for 4 study visits, for a total of 28 weeks. Recruitment will be competitive among the study sites, until the planned number of patients is randomized.

Masking Description
Appearance, including packaging and labelling, of the IMP (capsules, packaging) will not allow to recognize actual treatment (either ladarixin or placebo).
During the trial, blinding will be broken by the Investigator for emergency purposes only, where knowledge of the blinded treatment could influence further patient care.
