Multiple Ascending Dose Study of MK-5160 in Participants With Type 1 and Type 2 Diabetes Mellitus (MK-5160-002)

• Status: Completed
• Trial end date: 2018-01-30
• Target enrollment: 0
• Participant gender: All

Summary

This is a randomized, active- and placebo-controlled, double-blind trial of MK-5160 in participants with Type 1 diabetes mellitus (T1DM) and Type 2 diabetes mellitus (T2DM). This is a two-part trial, with three panels per part. T1DM (Part 1) and T2DM (Part 2) participants will be given daily fixed doses of MK-5160 in three predefined, increasing doses in each panel, or glargine (active comparator). The primary hypothesis of the trial is that at a dose with sufficient safety, the mean steady-state maximum level of glucose infusion rate (GIRmax) after MK-5160 administration in both T1DM and T2DM participants is between 1.5 and 4.5 mg/kg/min.

Criteria

Inclusion Criteria:

• For Part 1 (T1DM):

• Be male, or female of non-childbearing potential. A female of non-childbearing potential defined as a female who is postmenopausal without menses for at least 1 year and has a follicle stimulating hormone (FSH) value in the postmenopausal range upon pretrial (screening) evaluation OR a female who is status post hysterectomy, oophorectomy or tubal ligation.

• Be judged to be in good health

• Have a diagnosis of T1DM as defined by standard diagnostic criteria for ≥12 months at time study participation

• Be on stable doses of basal insulin over the 2-week period prior to screening and over the 2 weeks prior to dosing.

• Have a total daily insulin requirement (basal plus prandial) of ≤ 1.2 units/kg.

• Have a hemoglobin A1C (HbA1c) ≤10% at the time of study participation.

• Have a Body Mass Index (BMI) ≥18.5 kg/m^2 and ≤ 32 kg/m^2. BMI = mass (kg)/height (m)^2

• Be a non-smoker or smoker who uses no more than 5 cigarettes or equivalent (e.g., e-cigarettes) per day over the prior 3 month period also may be enrolled (at the discretion of the investigator). The subject must agree to follow the smoking restrictions defined by the clinical research unit (CRU).

• For Part 2 (T2DM):

• Be male, or female of non-childbearing potential. A female of non-childbearing potential defined as a female who is postmenopausal without menses for at least 1 year and has a FSH value in the postmenopausal range upon pretrial (screening) evaluation OR a female who is status post hysterectomy, oophorectomy or tubal ligation.

• Be judged to be in good health

• Have a diagnosis of T2DM as defined by standard diagnostic criteria for ≥12 month at time of study participation.

• T2DM participants are not required to have been on insulin. If on insulin, participants should have a total daily insulin requirement of ≤ 1.2 units/kg, and have been on stable doses of basal insulin over the 2-week period prior to screening and over the 2 weeks prior to dosing.

• Meet one of the following criteria:

1. Be on no anti-hyperglycemic agent (AHA), or on metformin monotherapy or metformin plus a dipeptidyl peptidase-4 (DPP4) inhibitor at stable doses for at least 8 weeks prior to screening, with a screening HbA1C ≥7.0 and ≤10.0%.

2. Be on either a sulfonylurea (e.g. glyburide) or an alpha-glucosidase inhibitors (e.g., acarbose) alone or in combination with metformin at stable doses for at least 8 weeks prior to screening with a screening HbA1C ≥7.0 and ≤9.0%. Participants on these medications must be willing to stop the sulfonylurea or alpha-glucosidase inhibitor after screening once they qualify for study participation.

• Have a BMI ≥18.5 kg/m^2 and ≤ 35.0 kg/m^2 BMI = mass (kg)/height (m)^2

• May be on selected standard medications for T2DM, including alpha-glucosidase inhibitors (e.g., acarbose), sulfonylureas (e.g. glyburide), DPP-4 inhibitors, and metformin. Participants on alpha-glucosidase inhibitors and/or sulfonylureas must stop these medications for at least one week prior to checking into the site and for the duration of the trial through the last dose of MK-5160/glargine. Participants on metformin or DPP-4 inhibitors may continue on their home dose for the duration of the trial. Participants on SGLT2 inhibitors (gliflozins), thiazolidinediones or GLP-1 agonists are excluded.

• Be a nonsmoker or smoker who uses no greater than 5 cigarettes or equivalent (e.g., e-cigarettes) daily over the prior 3 month period. Participants must agree to follow the smoking restrictions defined by the CRU.

Participants who have had situational depression may be enrolled in the trial at the discretion of the investigator.

• Has a history of clinically significant endocrine (excluding diabetes mellitus), gastrointestinal, cardiovascular, hematological, hepatic, immunological, renal, respiratory, genitourinary or major neurological (including stroke and chronic seizures) abnormalities or diseases. Participants with a history of uncomplicated kidney stones, as defined as spontaneous passage and no recurrence in the last 5 years, or childhood asthma may be enrolled in the trial at the discretion of the investigator.
