Brief summary

This study evaluated the safety and efficacy of ertugliflozin (MK-8835) in pediatric participants with T2DM on metformin with/without insulin. The primary hypothesis of the study was that the addition of ertugliflozin reduces hemoglobin A1C (HbA1C) more than the addition of placebo after 24 weeks of treatment.

Detailed description

Participants were randomized on Day 1 to the following arms: * 5 mg ERTU and placebo to 15 mg ERTU (5 mg Ertugliflozin) * placebo to 5 mg ERTU and placebo to 15 mg ERTU (Placebo) At Week 12, participants who met the up-titration criteria were re-randomized to the following arms for Weeks 12 to 54: * 5 mg ERTU and placebo to 15 mg ERTU (5 mg/5 mg Ertugliflozin) * 15 mg ERTU and placebo to 5 mg ERTU (5 mg/15 mg Ertugliflozin) Participants who did not meet the up-titration criteria remained on 5 mg ERTU and placebo to 15 mg ERTU from Week 12 to Week 54. The placebo arm continued receiving placebo from Week 12 to Week 54.

Participant flow

Pre-assignment details

Participants were screened up to 4 weeks before dosing. Participants were confirmed at screening to have T2DM for ≥2 years, conform to T2DM protocol specific requirements and be on stable metformin with or without insulin. The first randomization was stratified according to the following factors collected at screening: age (10 to 14 years of age/15 to 17 years) and insulin use (yes/no). Treatment randomization at Week 12 was stratified according to insulin use (yes/no) at screening.

Change From Baseline in Hemoglobin A1C (HbA1C) at Week 24 (Combined Ertugliflozin Versus Placebo)

Hemoglobin A1C is a measure of the percentage of glycated HbA1C in the blood. Participant whole blood samples were collected at baseline and Week 24 to determine the A1C change from baseline (i.e., % A1C at Week 24 minus % A1C at baseline). A negative number indicates a reduction in A1C level. Participants who met glycemic rescue criteria received glycemic rescue medication. The Bayesian mean change from baseline for each combined ertugliflozin and placebo are reported. Per protocol, the ertugliflozin arms are combined for this analysis.

Time frame: Baseline and Week 24

Population: This analysis includes all participants who received at least 1 dose of study treatment and excludes data following initiation of rescue therapy as well as data collected more than 5 days after the discontinuation of study medication.
