Post-Authorisation Safety Study of Lesinurad (SATURATES)

April 15, 2021 updated by: AstraZeneca
Non-interventional population-based prospective cohort study in multiple databases comparing patients with gout who initiate lesinurad in combination with an existing xanthine oxidase inhibitor (XOI) (lesinurad+XOI cohort) to a propensity score-matched cohort of similar patients from the same data source who continue treatment with XOI monotherapy (XOI mono cohort). Study will characterize the cardiovascular safety of lesinurad in combination with XOI in patients with gout aged 18+ years compared with similar patients who continue XOI monotherapy. Primary objective: to assess the relative incidence of major adverse cardiac events plus hospitalization for unstable angina (MACE+ events) in patients with gout in both cohorts. Secondary objectives: to describe the characteristics of the cohorts prior to matching; to assess the relative incidence of hospitalisation for acute kidney injury between the matched cohorts; to assess the relative incidence of individual MACE+ components in the matched cohorts.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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)

Study Population

All patients in this study will be 18 years of age or older, will have had at least 6 months (183 days) of continuous baseline data available before entering one of the cohorts, and will be current users of XOI monotherapy (i.e., > 1 dispensing/prescription of a study XOI in the 183-day baseline period prior to the index date and days' supply extending beyond the index date). The study population will include patients from one primary care database in Italy (Health Search) and another in Spain (Information System for Research in Primary Care [SIDIAP]), as well as two US health systems (the HealthCore Integrated Research DatabaseSM [HIRD] and Medicare).

Description

Inclusion Criteria:

  • More than one dispensing/prescription for an xanthine oxidase inhibotor (XOI) within the past 183 days prior to the index date and days' supply extending beyond the index date
  • A coded diagnosis of gout at any time in the past or on the index date
  • Age 18 years or older
  • Continuous enrolment in the database for the past 183 days

Exclusion Criteria:

  • Patients on urate-lowering therapy medications within 6 months prior to the index date to manage gout (probenecid, benzbromarone, or pegloticase) other than an XOI (allopurinol, febuxostat) or lesinurad (not including medications to treat gout flares).
  • Patients with severe renal impairment defined using clinical diagnostic codes (i.e., a diagnosis code of CKD stage IV, end-stage renal disease, or an indicator that eCrCl is < 30 mL/min at any time prior to the index date).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Major Adverse Cardiac Events (MACE+)
Time Frame: 2 year follow-up
MACE+ is a composite endpoint comprised of: hospitalisation for non-fatal AMI, stroke, or unstable angina and cardiovascular (CV) death. CV death includes the following causes, occurring in or out of the hospital: AMI, sudden cardiac, heart failure, CV procedures, CV haemorrhage, stroke, underlying cerebrovascular cause, other CV causes.
2 year follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hospitalisation for acute kidney injury (AKI) including renal failure (with AKI as the primary diagnosis)
Time Frame: 2 year follow-up

Confirmed cases of AKI require all three of the following criteria:

  • A diagnosis of renal injury or acute renal injury recorded as a primary hospital discharge diagnosis in the electronic database AND

  • An increase in serum creatinine at hospital admission or within 48 hours of hospital admission defined as follows:

    • Increase in serum creatinine by ≥ 1.5-fold from baseline where baseline is lowest value recorded within 1 year before the hospital admission date OR
    • Decrease in estimated glomerular filtration rate (eGFR) or actual 24-hour GFR by ≥ 50% from baseline where baseline is highest value recorded within 1 year before the hospital admission date OR
    • Estimated creatinine clearance (eCrCl) < 30 mL/min AND

  • Absence of all the following contraindications for lesinurad patients at any time prior to the index date:

    • A diagnosis code of chronic kidney disease stage IV or greater
    • eCrCl < 30 mL/min recorded at any time prior to the index date
2 year follow-up
Each individual component of MACE+
Time Frame: 2 year follow-up
This can be the hospitalisation for non-fatal AMI, stroke, or unstable angina and cardiovascular (CV) death.
2 year follow-up
