Study design details

Study design

The first phase of the study is the PASS phase and will be concluded after a study term of 5 years. Following the PASS phase, the study will continue as the WAYLIVRA Product Registry.

Main study objective

To evaluate the safety of WAYLIVRA on severe thrombocytopenia and bleeding in FCS patients according to the dose recommendation and dose algorithm in the Summary of Product Characteristics.

Setting

This study will be conducted in Europe at centers that manage patients with FCS, as well as by physicians specializing in lipid disorders (e.g., endocrinologists, cardiologists).
Patients from each participating site will be invited to participate in the study in order to minimize selection bias. For eligible patients who do not enroll, reason for non-enrolment will be collected.

Outcomes

Rate of Adverse Event Reporting of Severe Thrombocytopenia and Severe Bleeding
Rate and severity of adverse events with a focus on immunological events, hepatoxicity, renal toxicity and severe injection site reactions; Adherence rate to platelet monitoring and association of serious bleeding events; Dose and dose reduction rates; Pregnancy outcomes; Summarization of triglyceride reduction, pancreatitis prevention, and reduction in abdominal pain frequency and severity.

Data analysis plan

A PASS final analysis will be performed after the conclusion of the PASS phase which will be after 5 years in which at least data on 247 person-years of exposure have been collected in patients with genetically confirmed FCS and at high risk for pancreatitis, in whom response to diet and triglyceride lowering therapy has been inadequate, at which point a study report will be written. Complete analytical specifications for the study report, including tables and listings, will be included in the SAP, which will be prepared separately.
