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.

Detailed Description

Biosimilars were approved in 2007 by the EMA in EU and in 2010 by the TGA in Australia. This study will look at the retrospective data of patients that have switched from Darbepoetin Alfa to an approved epoetin alfa biosimilar. Data will be collected for the 26 week period prior to switch and a 26 week period post switch to a biosimilar. Data to be collected includes haemoglobin measurements, dose requirements, iron use, any transfusions, hospitalisations and other lab values including TSAT, Ferritin and albumin. Data from the study will be published.

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

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

The study population comprises prevalent haemodialysis (HD) patients treated at EU and Australian dialysis clinics after September 2008. Eligible patients will have received treatment with darbepoetin alfa for at least 26 weeks prior to being converted to an EMA/TGA-approved epoetin alfa biosimilar. At each participating study site, all potentially eligible patients are to be considered for enrolment.

Description

Inclusion Criteria

  • Patients ≥18 years of age

  • Patients with CKD on haemodialysis and fulfilling the following:

    • Received HD for at least 26 weeks prior to switching from treatment with darbepoetin alfa to treatment with an EMA/TGA-approved epoetin alfa biosimilar
    • Received darbepoetin alfa treatment i.v. for at least 26 weeks immediately prior to switching to an EMA/TGA-approved epoetin alfa biosimilar (breaks due to treatment being intentionally withheld are permitted)
    • Switched from darbepoetin alfa treatment to an EMA/TGA-approved epoetin alfa biosimilar at least 26 weeks prior to enrolment
    • Received at least one dose of an EMA/TGA-approved epoetin alfa biosimilar after switching from darbepoetin alfa treatment
  • Mean monthly Hb 10-12g/dL in the 12 weeks prior to switch
  • Stable darbepoetin alfa dose (i.e. no more than one increment or decrement of PFS) in the 12 weeks prior to switch
  • Patient or patient's legally acceptable representative has provided informed consent, if applicable according to local requirements

Exclusion Criteria:

  • Treatment with an ESA other than darbepoetin alfa during the 12 weeks prior to switch to biosimilar
  • More than 14 days' cumulative treatment with short-acting ESA during weeks 26-13 prior to switch to biosimilar
  • Subject received chemotherapy or major surgery during the 26 weeks prior to switch to biosimilar
  • Subject was enrolled in an interventional device or drug study at any time during the 52-week data observation period or within 30 days prior to commencement of the data observation period.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
