Study Endpoints

Primary Endpoints

Time to First Arteriovenous Graft (AVG) Thrombosis Event
From date of randomization until the date of first occurrence of an AVG thrombosis event, assessed up to approximately 37 months

An AVG thrombosis event is defined as the sudden occlusion of the participant's AVG requiring thrombectomy/thrombolysis, or clinical evidence of thrombosis with surgical, radiological or pathological conformation of an AVG thrombosis. A blinded independent clinical adjudication committee (CAC) adjudicated AVG thrombosis events. A time-to-event methodology was used to evaluate the results. The incidence rate is presented.

Number of Participants With An Adverse Event (AE)
Up to 134 days

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants that experience an AE will be reported.

Number of Participants Discontinuing the Study Due to an AE

Frequently asked questions about MK-2060

What is MK-2060?

MK-2060 is an investigational monoclonal antibody developed by Merck & Company, Inc. (ticker MRK) for nephrology indications. It is being studied in end-stage renal disease, renal dialysis, and venous thrombosis. The program is in Phase 2 development, and the clinical trials completed to date have enrolled a total of 549 participants.

What is MK-2060 used for in end-stage renal disease?

MK-2060 is being developed for use in end-stage renal disease and renal dialysis, where patients face elevated thrombotic risk, as well as in venous thrombosis. It remains investigational and has not been established as a treatment. Studies have enrolled adults with chronic kidney disease and end-stage kidney disease, including dialysis patients.

Who makes MK-2060?

MK-2060 is developed by Merck & Company, Inc., which trades under the ticker MRK. Merck sponsors the clinical program, including the Phase 1 studies conducted in the United States, Japan, Israel, and Romania, and the Phase 2 development stage for the asset in nephrology indications.

What phase is MK-2060 in?

MK-2060 is in Phase 2 clinical development. It is an investigational monoclonal antibody and has not been approved by the FDA. Four clinical trials have been completed, and no trials are currently active. The completed studies include Phase 1 trials in healthy participants and in patients with chronic and end-stage kidney disease.

What clinical trials is MK-2060 in?

Completed MK-2060 trials include NCT06582602 in healthy participants with venous thrombosis, NCT05769595 in older Japanese participants on dialysis, NCT05656040 in participants with chronic and/or end-stage kidney disease, and NCT05335005, which studied co-administration with clopidogrel in end-stage renal disease. All four were randomized, double-blind, and placebo-controlled.

How many participants were enrolled in MK-2060 trials?

Across the four completed MK-2060 clinical trials, 549 participants were enrolled in total. Individual study sizes ranged from 12 participants in the clopidogrel co-administration study to 23 in the healthy participant study. All trials were randomized, double-blind, and placebo-controlled, and none were biomarker-selected.
