What are the regulatory milestones and approval status?

  • Approved by the US Food and Drug Administration (FDA) in 2015.
  • Regulatory filings submitted to the European Medicines Agency (EMA) in Q2 2020.
  • Approval status in other key markets (Japan, Canada, Australia) pending or under review.

What is the size of the target market?
