Conversion Study From Epoetin Alfa to Monthly Peginesatide Injection in Patients With Chronic Kidney Disease on Dialysis (DIAMOND)

September 16, 2016 updated by: Takeda

A Phase 3b Single-Arm, Conversion Study From Epoetin Alfa to Monthly Peginesatide Injection in Patients With Chronic Kidney Disease on Dialysis

The purpose of this study is to understand the effects of a dialysis center switching its dialysis patients from using Epoetin alfa to peginesatide injection on hemoglobin levels and other parameters.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Monthly Erythropoiesis-Stimulating Agents (ESA) dosing, compared with the longstanding practice of dosing three times per week, represents a significant change in anemia treatment for dialysis patients. Because of the differences in the processes needed to support monthly dosing versus thrice weekly dosing, there is a need to prospectively identify and evaluate factors in the dialysis environment during center-level transition of patients from one ESA to another.

AFX01-18 is a Phase 3b open-label, single-arm conversion study that was conducted at 5 hemodialysis sites in the United States, and enrolled Chronic Kidney Disease (CKD) patients receiving outpatient, in-center hemodialysis. The study treatment period was approximately 12 months in duration. Participants received peginesatide injection for approximately six months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: peginesatide injection
In the first 6 months participants received standard of care treatment with epoetin (the Standard of Care Period [SCP]), followed by a 1-week erythropoiesis-stimulating agent (ESA)-Free Period, followed by peginesatide injection for 6 months (the Peginesatide Treatment Period [PTP]).
Drug: Epoetin
Commercially available epoetin alfa administered weekly, twice weekly, or thrice weekly at an initial starting dose, frequency of administration, and mode of administration (intravenous [IV] or subcutaneous [SC]) individually determined for each participant using the site's usual standard of care. Subsequent dose adjustments or dose holds may have been made in order to maintain a hemoglobin concentration of <11 g/dL.
Drug: Peginesatide
Administered as a once monthly intravenous (IV) or subcutaneous (SC) injection. The initial dose of peginesatide injection was based on the final weekly dose of epoetin administered in the SCP; subsequent doses may have been adjusted in order to maintain hemoglobin concentrations at <11 g/dL.
