Summary

This trial is testing olezarsen, a medication for people with FCS who have already tried another treatment. It aims to see if olezarsen is safe and effective by lowering a protein that affects blood fat levels.

Who is the study for?
This trial is for adults with Familial Chylomicronemia Syndrome (FCS) who have tried a drug called volanesorsen but stopped due to side effects. They can't be on systemic steroids or have had plasma apheresis recently, and should not switch their current medications like statins or omega-3s during the study.
What is being tested?
The trial tests Olezarsen's safety and how it affects the body in FCS patients previously treated with volanesorsen. It looks at how the body processes Olezarsen and its impact on lipid levels in participants.
What are the potential side effects?
While specific side effects of Olezarsen are not listed here, similar drugs may cause injection site reactions, flu-like symptoms, liver issues, potential kidney problems, and possible interactions with other medications.
