Tegsedi (Inotersen)
NDA #211172
REMS last update: 08/24/2023



What is the purpose of the REMS?

The goal of the TEGSEDI REMS is to mitigate the risk of serious bleeding with severe thrombocytopenia and the risk of glomerulonephritis associated with TEGSEDI by:

  1. Ensuring prescribers are educated on the risk of serious bleeding with severe thrombocytopenia and the risk of glomerulonephritis associated with TEGSEDI.
  2. Ensuring prescribers are educated and adhere to the following:
    • Counsel patients on how to recognize and respond to signs and symptoms of serious bleeding and glomerulonephritis.
    • Enroll patients in the TEGSEDI REMS.
    • Submit documentation that periodic monitoring of patients is being done to identify severe thrombocytopenia, serious bleeding with severe thrombocytopenia, and glomerulonephritis.

  3. Ensuring patients are informed on the following:
    • How to recognize and respond to signs and symptoms of serious bleeding and glomerulonephritis.
    • The need to have their platelet count and renal function monitored.

  4. Enrollment of all patients in a registry to further support long-term safety and safe use of TEGSEDI.

What do participants need to know?

Below is a general overview of the REMS for all REMS participants (e.g., patients, pharmacies, and healthcare providers). See the application holder(s) REMS Website or the approved REMS materials for more information.
