Competitive Pressure

The most relevant competitive pressure comes from U.S. FDA Approves Pfizer’s HYMPAVZI for the Treatment of Two Additional Hemophilia A or B Patient Populations with Significant Medical Need (Pfizer) — sponsor/company relevance (pfizer). Secondary pressure from FDA Approves Veklury as First Treatment for COVID-19.
