comparison of insulin tregopil (in-105) with insulin aspart in type 2 diabetes mellitus patients

Conditions: Type2 Diabetes Mellitus

Summary: this is an open label phase ii/iii study to evaluate the efficacy and safety of test drug, insulin tregopil (in-105) compared with insulin aspart (iasp) in type 2 diabetes mellitus patients. on stable dose of metformin and insulin glargine. the study will be conducted in 2 parts, part i and part ii. the study duration will be approximately 37 weeks for part i and for part ii of the study respectively

part i of the study is a phase ii multi-center, randomized, open label clinical study to evaluate the efficacy and safety of insulin tregopil (2 dose levels: 30 mg, 45 mg) compared with iasp in the treatment of t2dm patients. part ii of the study is the phase iii, multi-center, randomized, open label clinical study to evaluate the efficacy and safety of insulin tregopil (30 mg or 45 mg based upon the outcome of part i data) compared with iasp in the treatment of t2dm patients. for part i and part ii, the study duration will be approximately 37 weeks (3 weeks screening, 8 weeks run-in, 24 weeks treatment, 2 weeks safety follow-up). an independent data and safety monitoring board (dsmb) will evaluate the data from part i of the study. part ii of the study will be initiated after approval from the office of drugs controller general of india (dcgi) and data safety monitoring board (dsmb) recommendation based on review of data from part i of the study. in both part i and part ii of the study, t2dm patients with glycated hemoglobin (hba1c) 7.5 to 10% (both inclusive), on stable dose of metformin ± oral antidiabetic drugs (oads) ± basal insulin who are eligible for insulin glargine administration as per investigator discretion and who satisfy the selection criteria will be enrolled. the eligible patients will go through a run-in period of 8 weeks. at the end of 8 weeks run-in period, eligibility will be checked and patients will enter the treatment period of 24 weeks and will be allocated to 3 treatment arms (part i) or randomized to 2 treatment arms (part ii); if found eligible for randomization. a total of 90 patients in part 1 and 268 patients in part 2 will be randomised to the treatment arms from approximately 40 centers in india.
