Factor VIII Threshold

Efficacy & safety

Patient demand and expectation has transformed over the decades

Kovaltry_logo

Different patients have different needs – and require treatment targeted at different FVIII threshold levels4

Patient Need Sedentary lifestyle Mid-risk activity Moderate risk activity High risk activity
Treatment Threshold (%) 1 3 5 10+

Adapted from lorio et al. 20174

Until the mid-1970s, patients were often advised to avoid physical activity1

We now know that being able to participate in physical activity is important to patients and improves joint stability2,3

While patient-bleeding phenotype will be influential, it’s generally accepted that today’s prophylaxis goal is to keep rFVIII levels as HIGH as possible for as long as possible4,5,6
