Phase III Trial to Evaluate the Efficacy and Safety of LC15-0444 Compared With Sitagliptin Added to Ongoing Metformin Therapy in Patients With Type 2 Diabetes

May 17, 2012 updated by: LG Life Sciences

A Multicenter, Multinational, Randomized, Active-controlled, Parallel Group, Double-blind, Phase III Trial to Evaluate the Efficacy and Safety of LC15-0444 Compared With Sitagliptin Added to Ongoing Metformin Therapy in Patients With Type 2 Diabetes Inadequately Controlled With Metformin Alone

Double-blind, randomized, multicenter, multinational (South Korea and India), parallel group study The study was divided into three parts: part 1 was a screening period started with an initial 2 weeks of exercise/diet program; part 2 was a double-blind treatment period during which eligible patients were randomized to Sitagliptin 100 mg qd (once daily), LC15-0444 25 mg bid (twice daily), or LC15-0444 50 mg qd groups and received the assigned treatment for 24 weeks; part 3 was for those patients who completed part 1 & 2 and consented to receive another 28 weeks of treatment with LC15-0444 50 mg qd.

Screening tests were performed on the patients who had given the written informed consent. After 2-week exercise/diet program according to the generally recognized guideline, eligible patients were assigned one of three treatment groups with 1:1:1 ratio. During the total of 24-week treatment period of part 2, each patient visited the study site at Week 6, 12, 18, and 24. Completing double-blind treatment for 24 weeks, each patient was asked to provide consent to participate in the part 3 of the study where all the patients were to receive LC15-0444 50 mg once daily. During 28-week treatment period of the part 3, each patient visited the study

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: LC15-0444 25 mg bid
LC15-0444 25 mg bid(twice daily)added on Metformin therapy
Each patient was given 3 different bottles of study drugs that comprised of two morning bottles and one evening bottles. Each morning bottle contained LC15-0444 25 mg or 50 mg or Sitagliptin 100mg(depending on the randomized group) or its matching placebo while the evening bottle contained LC15-0444 25 mg or its matching placebo. Patient was instructed to take 1 tablet from each bottle at regular times in the morning and evening every day during the 24-week double-blind treatment period.
Experimental: LC15-0444 50 mg qd
LC15-0444 50 mg qd(once daily) added on Metformin therapy
Each patient was given 3 different bottles of study drugs that comprised of two morning bottles and one evening bottles. Each morning bottle contained LC15-0444 25 mg or 50 mg or Sitagliptin 100mg(depending on the randomized group) or its matching placebo while the evening bottle contained LC15-0444 25 mg or its matching placebo. Patient was instructed to take 1 tablet from each bottle at regular times in the morning and evening every day during the 24-week double-blind treatment period.
Active Comparator: Sitagliptin 100mg qd
Sitagliptin 100 mg qd (once daily) added on the Metformin therapy
