Study Endpoints

Primary Endpoints

Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at Week 8
Baseline and up to Week 8

Blood samples were collected at baseline and after 8 weeks of treatment to assess mean percent change in LDL-C. Based on a constrained longitudinal analysis (cLDA) model including terms for treatment, time, baseline statin intensity, baseline renal function, and the interaction of treatment by time. The percent change from baseline in LDL-C at week 8 was reported.

Percentage of Participants Who Experienced One or More Adverse Events (AEs)
Up to approximately 17 Weeks

An AE was 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 could 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 percentage of participants who experienced at least one AE was reported.

Percentage of Participants Who Discontinued Study Intervention Due to AEs
Up to approximately 9 Weeks

An AE was 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 could 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 percentage of participants who discontinued study intervention due to AEs was reported.

Time to Maximum Plasma Concentration (Tmax) of MK-0616
Predose and at designated timepoints up to 168 hours postdose

Blood samples will be collected at pre-specified timepoints to determine the Tmax of MK-0616.

Frequently asked questions about Enclitide Chloride

What is Enclitide Chloride used for?

Enclitide Chloride is being developed for the treatment of hypercholesterolemia, including familial hypercholesterolemia. It is an investigational oral therapy studied in adults with elevated cholesterol levels. The drug has been evaluated in a Phase 2 clinical trial but is not yet approved for any indication.

How does Enclitide Chloride work?

Enclitide Chloride is an oral PCSK9 inhibitor. It belongs to the peptide drug class, as indicated by the -tide suffix. By inhibiting PCSK9, it is designed to lower cholesterol levels in patients with hypercholesterolemia. The exact mechanism of action is consistent with other PCSK9 inhibitors.

Who is developing Enclitide Chloride?

Enclitide Chloride is being developed by Merck & Company, Inc., which trades under the ticker symbol MRK. Merck is responsible for the clinical development of this oral PCSK9 inhibitor for hypercholesterolemia.

What phase is Enclitide Chloride in?

Enclitide Chloride is in Phase 2 clinical development. A Phase 2 trial has been completed, but the drug is not yet approved by the FDA or any regulatory agency. It remains an investigational therapy for hypercholesterolemia.

What clinical trials is Enclitide Chloride in?

Enclitide Chloride has been studied in a Phase 2 clinical trial, NCT05261126, titled "A Study of the Efficacy and Safety of Enclitide Chloride (MK-0616 Oral PCSK9 Inhibitor) in Adults With Hypercholesterolemia (MK-0616-008)." This completed trial enrolled 381 participants across multiple countries, including the United States, Germany, Japan, Mexico, Norway, South Korea, Turkey, and the United Kingdom.

Is Enclitide Chloride the same as MK-0616?

Yes, Enclitide Chloride is also known as MK-0616. The clinical trial identifier NCT05261126 refers to it as MK-0616 Oral PCSK9 Inhibitor. Both names refer to the same investigational drug developed by Merck for hypercholesterolemia.
