Ertugliflozin Type 2 Diabetes Mellitus (T2DM) Pediatric Study (MK-8835/PF-04971729) (MK-8835-059)
A Phase 3, Multicenter, Double-blind, Randomized, Placebo-controlled Clinical Study to Evaluate the Safety and Efficacy of Ertugliflozin (MK-8835/PF-04971729) in Pediatric Participants (Ages 10 to 17 Years, Inclusive) With Type 2 Diabetes Mellitus

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.

Outcome Measures
Primary Outcomes (5)
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.
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.
Up to Week 24
Number of Participants Who Experienced an AE Up to Week 54
An adverse event 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.
Up to Week 54
Number of Participants Who Discontinued Study Treatment Due to an AE Up to Week 24

Study Arms (4)
Ertugliflozin 5 mg
EXPERIMENTALAll 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.
Ertugliflozin 5 mg/5 mg
EXPERIMENTALAll participants initially received 5 mg ERTU QD and placebo to 15 mg ERTU QD until Week 12. Participants remained on their background metformin with/without insulin treatment throughout the study. Participants who met the up-titration criteria at the WK12 second randomization were re-randomized to remain on 5 mg ERTU and placebo to 15 mg ERTU from WK12 to WK54.
Ertugliflozin 5 mg/15 mg
EXPERIMENTALAll participants initially received 5 mg ERTU QD and placebo to 15 mg ERTU QD until Week 12. Participants remained on their background metformin with/without insulin treatment throughout the study. Participants who met the up-titration criteria at the WK12 second randomization were up-titrated to 15 mg ERTU and placebo to 5 mg ERTU from WK12 to WK54.
Placebo
PLACEBO COMPARATORAll participants received matched placebo to 5 mg ERTU and 15 mg ERTU from baseline to WK54. Participants remained on their background metformin with/without insulin treatment throughout the study.
Interventions
Ertugliflozin 5 mg, oral, 1 tablet QD
Ertugliflozin 15 mg, oral, 1 tablet QD
Placebo to ertugliflozin 15 mg, oral, 1 tablet QD
Placebo to ertugliflozin 5 mg, oral, 1 tablet QD
Participants on insulin at screening continued to receive a stable dose of background insulin. The initiation and titration of insulin for rescue therapy was at the discretion of the investigator, based on local/regional/country guidelines.
Participants received stable dose of background metformin.
