iGlarLixi CGM Study in Chinese T2D Individuals After OADs

Official title

A 20-week, Multicenter, Prospective, Parallel-group Treatment, Open-label, 2-Arm, Phase 4, Randomized Study to Evaluate the Efficacy of iGlarLixi Versus Gla-100 on Glycemic Time in Range (TIR) From Continuous Glucose Monitoring (CGM) in Chinese Insulin Naïve Patients With Type 2 Diabetes (T2D) Inadequately Controlled With Oral Antidiabetics

Overview

This study is an open-label, 1:1 randomized, active-controlled, 2-arm, 20-week treatment duration, parallel-group, multicenter, phase IV study to evaluate the effect of iGlarLixi versus Gla-100 on glycemic control measured as TIR from CGM device in Chinese insulin naïve patients with T2D inadequately controlled with OADs. At the end of the screening period, eligible participants will be randomized to one of two treatment groups (iGlarLixi or Gla-100 group). The randomization (1:1) will be stratified by values of HbA1c at screening (\<8.0%, ≥8.0%), and background treatment (metformin only, metformin+SGLT-2i). Study details include: * The study duration per participant will be approximately up to 24 weeks. * The treatment duration will be up to 20 weeks. * The number of visits will be 14 visits including 9 times of on-site visits and 5 times of phone call visits in total during screening and treatment periods. On-site every 1 week will be from screening till randomization (Week 0), then on site or phone call visit every 2 weeks till Week 12, then every 3 weeks till Week 18, and the End of Treatment visit will be conducted at Week 20. There will be a safety follow-up by a phone call visit (End of Study) in 3 days (-1/+3 days) after the last dose of the treatment. * Health measurement/Observation: change in TIR as the primary endpoint * Intervention name: iGlarLixi and Gla-100 * Participant gender: male and female * Participant age range: adults at least 18 years of age * Condition/disease: type 2 diabetes * Study hypothesis: compared to Gla-100, iGlarLixi will demonstrate a superiority therapeutic effect on glycemic control assessed by change in TIR measured with CGM from baseline to Week 20 in the study participants.

Interventions

• Drug iGlarLixi (insulin glargine/lixisenatide)
  iGlarLixi will be supplied as a sterile aqueous solution in a pen-injector. There will be 2 pen-injectors with different insulin glargine/lixisenatide fixed ratios which allow insulin glargine titration from 5 U/day to 40 U/day while limiting lixisenatide dose to a maximum of 20 μg/day: \- iGlarLixi must not be mixed with other insulins nor diluted.
• Drug Gla-100 (insulin glargine)
  Gla-100 will be supplied as a 3 mL sterile aqueous solution for SC injection in a pre-filled disposable Gla-100 SoloStar® pen containing 300 U insulin glargine (100 U/mL). Doses could be set in the range of 5 to 80 U in increments of 1 unit.

Primary outcome measures

• Superiority of mean change in the percentage of TIR [3.9-10.0 mmol/L (70-180 mg/dL)] [Time frame: from baseline to Week 20]

Secondary outcome measures (12)

• 2a Proportion (%) of participants achieving TIR target as >70% [Time frame: Week 20]
• 2b Change (%) in TAR >10.0 mmol/L (>180 mg/dL) [Time frame: from baseline to Week 20]
• 2c Change (mg/dL) in mean daily glucose [Time frame: from baseline to Week 20]
• 2d Proportion (%) of participants achieving composite target of TIR as >70% [3.9-10.0 mmol/L (70-180 mg/dL)] with TAR as <25% [>10.0 mmol/L (>180 mg/dL)] with TBR as <4% [<3.9 mmol/L (<70 m)/dL)] [Time frame: Week 20]
• Change (%) in coefficient of variation (CV) [Time frame: from baseline to Week 20]
• Change (%) in the percentage of time in tight range (TITR) [3.9-7.8 mmol/L (70-140 mg/dL)] [Time frame: from baseline to Week 20]
• Proportion (%) of participants achieving TITR [3.9-7.8 mmol/L (70-140 mg/dL)] >50% [Time frame: Week 20]
• Proportion (%) of participants achieving ≥5% TIR improvement [Time frame: from baseline to Week 20]
• Proportion (%) of participants achieving ≥10% TIR improvement [Time frame: from baseline to Week 20]
• Change (%) in TAR >13.9 mmol/L (>250 mg/dL) [Time frame: from baseline to Week 20]
• Change (%) in time below range (TBR) [Time frame: from baseline to Week 20]
• Change in mean glucose standard deviation (SD) [Time frame: from baseline to Week 20]
