Single Ascending Dose Study of MK-1092 in Healthy Participants and in Participants With Type 1 and Type 2 Diabetes Mellitus (MK-1092-001)

Merck Sharp & Dohme LLC69 enrolled

Overview

This is an active- and placebo-controlled, single-site, four-part trial of MK-1092 in healthy adult participants, in participants with type 1 diabetes mellitus (T1DM), and in participants with type 2 diabetes mellitus (T2DM). The primary hypothesis for this study is that at a dose with sufficient safety, the mean maximal glucose infusion rate (GIRmax) after single subcutaneous (SC) administration of MK-1092 in adult participants with T1DM is within an acceptable range. (Part 3)

There will be 4 parts in this study. In Part 1, healthy adult participants will be randomized to receive blinded MK-1092 subcutaneously (SC) or glargine SC, as a single dose under the euglycemic clamp. Once a safe and tolerated dose that achieves GIRmax is identified in Part 1, Part 2 will start. In Part 2, 4 different healthy adult participants will be enrolled in a single panel and receive open-label MK-1092 SC as a single dose under the euglycemic clamp and also receive an intravenous infusion of Humalog®. In Part 3, adult participants with T1DM will be randomized to receive blinded MK-1092 SC or insulin glargine SC, as a single dose under the euglycemic clamp. Part 4 includes a 3-period (Periods 1, 2, and 3) design that will explore up to 3 single subcutaneous doses of MK-1092 or insulin glargine in participants with Type 2 diabetes mellitus.

Outcomes

Primary Outcomes

Number of Participants Who Experienced an Adverse Event (AE)

An adverse event is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. Adverse events that occurred beyond 14 days of dosing were considered Post-Trial AEs. Given the half-life of MK-1092 and glargine, any events observed beyond 14 days would not be considered a result of study drug and were therefore presented together.

Time frame: Up to 112 days

Number of Participants Who Discontinued the Study Due to an AE

Time frame: Up to 58 days

GIRmax After a Single Dose Administration of Subcutaneous MK-1092 or Glargine to Adult Participants With Type 1 Diabetes Mellitus (T1DM) (Part 3)

The GIRmax required to maintain blood glucose at each participants' individual clamp target, following administration of MK-1092 SC or glargine SC was determined by use of a continuous glucose infusion during the euglycemic clamp so that glucose levels remained in the euglycemic range and hypoglycemia was prevented. Blood glucose was monitored frequently (\~every 5 minutes), allowing rapid changes to the rate of glucose infusion. Mean and 95% CI were based on a linear fixed effects model containing a fixed effect for treatment (MK-1092 Doses, Glargine). In Part 3, 4 participants (across 2 dosing panels) received glargine. These 4 participants were analyzed together given the small numbers and the same treatment (same dose of glargine) received.
