Study of Pharmacokinetics of a Single IV Dose of CB-238,618 in Subjects With Varying Degrees of Renal Impairment Compared to Healthy Subjects (MK-6183-001)

Cubist Pharmaceuticals LLC, a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA)40 enrolled

Overview

The purpose of this study is to characterize the effect of renal function on the plasma, urine, and dialysate pharmacokinetic profile of MK-6183 (CB-238,618) in humans. The study will also assess the safety profile and tolerability of MK-6183 in healthy participants, participants with varying degrees of renal impairment (RI), or participants with end-stage renal disease (ESRD) requiring hemodialysis (HD), based on estimated glomerular filtration rate (eGFR).

Inclusion Criteria: * Participants who are healthy; or who have mild, moderate, or severe RI; or who have ESRD requiring HD. Participants with ESRD requiring HD should have been receiving HD 3 times per week for at least 3 months preceding the initial dose in this study Exclusion Criteria: * For healthy participants (Group A): history or presence of any clinically significant illness (e.g., cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, musculoskeletal, or psychiatric) or any other condition, including clinically significant anemia, which in the opinion of the investigator would jeopardize the safety of the participant or the validity of the study results * For participants with RI (Groups B to E): as above, except that RI and other medical conditions commonly associated with renal impairment (eg, hypertension, diabetes, which should be stable for at least three months preceding the initial dose of study medication in this study) are allowed * Clinically significant abnormalities on physical examination, medical history, 12-lead electrocardiogram (ECG), vital signs, or laboratory values, as judged by the investigator or designee. Subjects with renal impairment should have clinical laboratory values consistent with their disease and approved by the investigator * Evidence of clinically significant hepatic impairment including alanine aminotransferase or aspartate aminotransferase \>1.5 × upper limit of normal (ULN) or bilirubin \>1 × ULN * Hemoglobin \<8 g/dL, unless considered stable and not clinically significant in the opinion of the investigator in subjects with ESRD and on HD * Participants with renal impairment who are not on a chronic stable drug regimen, defined as starting a new drug or changing dosage within 14 days prior to administration of study medication, except for drugs administered in relationship to HD * Participants with fluctuating or rapidly deteriorating renal function (assessment of the stability of the subject's renal function will be determined by the investigator) * Participant has a currently functioning renal transplant and/or has been on significant immunosuppressant therapy, as determined by the investigator, within the last 6 months

Outcomes

Primary Outcomes

Area Under the Plasma Concentration-time Curve (AUC) From Dosing to Last Measurable Concentration (AUC0-last) of MK-6183

AUC0-last is the area under the plasma concentration-time curve from the time of dosing to the last post-dose measurable concentration. Blood samples for Group E were collected both prior to and during HD (Period 1) and after HD (Period 2) \[data from Periods 1 and 2 were analyzed separately\]. In Period 1, HD commenced 3.5 hours post-dose (HD duration was 3.5 to 4 hours) and sample collection continued until 48 hours post-dose. The specific time frame of plasma sample collection for Group E: Period 1 was pre-dose, 0.5 hours post-dose, EOI, 1.5 hours post-dose, 2 hours post-dose, 3 hours post-dose (pre-HD), 3.5 hours post-dose with HD, 5 hours post-dose with HD, pre-end of HD, 30 min post-HD, 1 hour post-HD, 2 hours post-HD, 12 hours post-dose, 24 hours post-dose, and 48 hours post-dose.

Time frame: Groups A to D & Group E: Period 2: Pre-dose and 0.5, 1 (end of infusion; EOI), 1.5, 2, 3, 6, 12, 24, 48, and 72 hours post-dose

AUC From Dosing to ∞ (AUC0-∞) of MK-6183

AUC0-∞ is the extrapolated area under the plasma concentration-time curve from the time of dosing to infinity. Blood samples for Group E were collected both prior to and during HD (Period 1) and after HD (Period 2) \[data from Periods 1 and 2 were analyzed separately\]. In Period 1, HD commenced 3.5 hours post-dose (HD duration was 3.5 to 4 hours) and sample collection continued until 48 hours post-dose. The specific time frame of plasma sample collection for Group E: Period 1 was pre-dose, 0.5 hours post-dose, EOI, 1.5 hours post-dose, 2 hours post-dose, 3 hours post-dose (pre-HD), 3.5 hours post-dose with HD, 5 hours post-dose with HD, pre-end of HD, 30 min post-HD, 1 hour post-HD, 2 hours post-HD, 12 hours post-dose, 24 hours post-dose, and 48 hours post-dose. For statistical analyses, Group A is the reference and least squares (LS) mean ratios for tests (Groups B to E) are calculated as test/reference; Group E: Period 1 and Group E: Period 2 were also compared.
