Ladarixin as Adjunctive Therapy to Improve Insulin Sensitivity and Glucometabolic Outcomes in Type 1 Diabetes

Withdrawn before enrolling · Phase 2 · Has a placebo group

Conditions studied: Type I Diabetes

In brief

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.

Who can join

Age: 21 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

clinical diagnosis of autoimmune T1D as documented by positive T1D diabetes-related autoantibodies [the presence at diagnosis of at least one or more of - Insulin autoantibodies (IAA), Anti-GAD (GAD65), Anti-IA2 (IA2), Zinc Transporter 8 (ZnT8) must be documented from medical records or new laboratory measurement (not including IAA)];
age 21-65 years at the time of consent;
T1D duration =>5 years;
current insulin standard of care (ISOC), either use of an insulin pump or a stable dose level and dose frequency (i.e. established dose range that does not fluctuate beyond 1SD of the median over a period of the last two months prior to enrollment), multiple daily injections of insulin (at least 3 injections per day) for the last two months prior to enrollment, with no plans to switch the modality of insulin administration during the 4 months following screening (e.g., injection user switching to a pump, pump user switching to injections);
HbA1c between 7.5%-10.0%, inclusive, as per results of screening laboratory measurement;
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;
subject is overweight or obese with a BMI of between 25-40 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 written informed consent prior of any study-related procedure not part of standard medical care.

You may not qualify if…

patients with known or suspected hypersensitivity to 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);
use of medications for weight reduction (such as: Belviq (lorcaserin), Qsymia (Phentermine + topiramate), Orlistat (xenical));
use of a medication such as stimulants, antidepressants and/or psychotropic agents that could affect weight gain or glycemic control of T1D;
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)];
any medications known to influence glucose tolerance (e.g. beta-blockers, angiotensin-converting enzyme inhibitors, interferons, quinidine antimalarial drugs, lithium, niacin, etc.);
evidence of cardiac QTcF > 470 msec and/or any history of significant cardiovascular disease/abnormality;
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;
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).
clinical diagnosis of celiac disease that is in poor control as defined by most recent tissue transglutaminase (tTG) that is in the abnormal range;
history of ≥1 Diabetic Ketoacidosis (DKA) events in the past 6 months;
history of ≥1 severe hypoglycemic events (cognitive impairment that required assistance to treat) in the past 6 months;
hypoalbuminemia defined as serum albumin < 3 g/dL ;
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];
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;
poor accessibility to veins for blood collection;
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;
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;
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).
