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.
Participants were randomized on Day 1 to the following arms:
At Week 12, participants who met the up-titration criteria were re-randomized to the following arms for Weeks 12 to 54:
The placebo arm continued receiving placebo from Week 12 to Week 54.
The main inclusion criteria include but are not limited to the following:
Exclusion Criteria:
The main exclusion criteria include but are not limited to the following:
All participants initially received 5 mg ertugliflozin (ERTU) once daily (QD) and placebo to 15 mg ERTU QD until Week 54 (WK54). At Week 12 (WK12), participants who did not meet the up-titration criteria remained on 5 mg ERTU and placebo to 15 mg ERTU. Participants remained on their background metformin with/without insulin treatment throughout the study.

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
Number of Participants Who Experienced an Adverse Event (AE) Up to Week 24
An adverse event -- Select --is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. Per protocol, the ertugliflozin arms are combined for this analysis.
