Approved Risk Evaluation and Mitigation Strategies (REMS)

Filspari (sparsentan)
NDA #216403
REMS last update: 12/20/2023



What is the purpose of the REMS?

The goal of the FILSPARI REMS is to mitigate the risks of hepatotoxicity and embryo-fetal toxicity associated with FILSPARI:

  1. Objective 1: Monitor for elevations in liver enzymes in patients exposed to FILSPARI
  2. Objective 2: Ensure that patients who can become pregnant are not pregnant before initiating FILSPARI
  3. Objective 3: Minimize exposure in patients who may become pregnant while taking FILSPARI
