June 8, 2015 updated by: Merck Sharp & Dohme LLC

A Double-Blind, Randomized, Placebo-Controlled, Single-Dose Crossover Study to Assess the Safety and Tolerability of MK0893 Coadministered With Propranolol Hydrochloride in Patients With Type 2 Diabetes

This study will assess the effect of combined treatment with MK0893 plus propranolol versus placebo plus propranolol on hypoglycemia.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Propanolol + Placebo > Propanolol + MK0893
Participants received propanolol for 7 weeks. On Day -1 of Period 1 (Study Visit 6), single dose MK0893-matched placebo was added and propanolol was continued. After Period 1, participants underwent a 3-week wash-out while continuing to receive propanolol. Following the washout, participants were treated with a single dose of MK0893 on Day 21 (Visit 8).
Single dose of MK0893 1000 mg (ten 100 mg tablets)
Single dose of placebo to MK0893 (ten tablets)
Propranolol tablets titrated up to 80 mg three times daily over a four week period. Total treatment was approximately 7 weeks.
Placebo Comparator: Propanolol + MK0893 > Propanolol + Placebo
Participants received propanolol for 7 weeks. On Day -1 of Period 1 (Study Visit 6), single dose MK0893 was added and propanolol was continued. After Period 1, participants underwent a 3-week wash-out while continuing to receive propanolol. Following the washout, participants were treated with a single dose of MK0893-matched placebo on Day 21 (Visit 8).
Single dose of MK0893 1000 mg (ten 100 mg tablets)
Single dose of placebo to MK0893 (ten tablets)
Propranolol tablets titrated up to 80 mg three times daily over a four week period. Total treatment was approximately 7 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recovery Time (Rt[65] From Insulin-induced Hypoglycemia
Time Frame: From the time of hypoglycemic clamp (t=0 minutes) through 270 minutes
Rt(65) defined as the time to recover from hypoglycemia (blood glucose level of 50 mg/dL) to an arterialized venous blood glucose of 65 mg/dL. At t= -60 minutes on the morning of Day 1 (Visit 6) or Day 22 (Visit 8), a hypoglycemic clamp was used via an increased insulin infusion rate to achieve blood glucose concentrations of 50 mg/dL (2.8 mmol/L) within ~30-90 minutes. At the end of the 30-minute hypoglycemic clamp interval, insulin and glucose infusions were terminated, and the time to recover from hypoglycemia to 65 mg/dL Rt(65) was determined. Rt(65) was followed up to 270 minutes
From the time of hypoglycemic clamp (t=0 minutes) through 270 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum Plasma Concentration (Cmax) and Concentration Average Over 8-12 Hours (C[Ave] 8-12 hr) Post Single Dose MK0893
Time Frame: From time of MK0893 administration through 24 hours post-dose

Cmax was the maximum or "peak" concentration of MK0893 observed after its administration.

Approximate C(ave 8-12) was the MK0893 concentration average over 8-12 hours post-dose and was computed as the Area Under the Curve over 8-12 hours post-dose (AUC [8-12]) ÷ 4

From time of MK0893 administration through 24 hours post-dose
Plasma Concentration at 32 Hours (C[32hr]) Post Single Dose MK0893
Time Frame: From time of MK0893 administration through estimated 32 hours post-dose
Plasma concentration of single dose MK0893 was measured from time of administration to 24 hours post-dose and extrapolated out to 32 hours post-dose using the plasma concentration vs. time curve
From time of MK0893 administration through estimated 32 hours post-dose
Number of Participants With An Adverse Event (AE)
Time Frame: From time of administration of study treatment through end of Post-Study (up to 21 days after administration of last dose of study treatment).

An AE was defined as any unfavorable and unintended change in the

structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. This also included any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product.

From time of administration of study treatment through end of Post-Study (up to 21 days after administration of last dose of study treatment).
Number of Participants Who Discontinued Study Treatment Due To AEs
Time Frame: From time of first administration of study treatment to time of last administration of study treatment (up to Day 21)

An AE was defined as any unfavorable and unintended change in the

structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. This also included any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product.

From time of first administration of study treatment to time of last administration of study treatment (up to Day 21)
