What was studied

The primary objective of the trial focused on the annualized bleed rate (ABR) of treated bleeds during treatment with HYMPAVZI, compared to the mean ABR of factor-based on-demand and routine prophylactic treatment in patients.

The secondary objective of the study included evaluation of HYMPAVZI prophylaxis (compared with on-demand and routine prophylactic factor-based treatment) based on the incidences of treated joint bleeds, treated target joint bleeds, treated spontaneous bleeds, and total bleeds.

Study design

HYMPAVZI delivered proven bleed protection

Primary objective

Fewer treated bleeds

HYMPAVZI reduced the number of treated bleeding episodes in the clinical trial.

ABR of treated bleeds with HYMPAVZI:

92% image

lower than on-demand

(3.18 ABR vs 38.00 ABR)

ABR of treated bleeds with HYMPAVZI:

35% image

lower than routine
prophylaxis

(5.08 ABR vs 7.85 ABR)

Secondary objective

Fewer joint bleeds

ABR of joint bleeds with HYMPAVZI:

91% image

lower than on-demand

(2.83 ABR vs 32.86 ABR)

ABR of joint bleeds with HYMPAVZI:

27% image

lower than routine
prophylaxis

(4.13 ABR vs 5.66 ABR)

Secondary objective

Fewer target joint bleeds

If a joint has had 3+ bleeds in a span of 6 months, it's considered a target joint.

ABR of target joint bleeds with HYMPAVZI:

92% image

lower than on-demand

(1.84 ABR vs 23.18 ABR)

ABR of target joint bleeds with HYMPAVZI:

25% image

lower than routine
prophylaxis

(2.51 ABR vs 3.36 ABR)

Secondary objective

Fewer spontaneous bleeds

ABR of spontaneous bleeds with HYMPAVZI:

92% image

lower than on-demand

(2.44 ABR vs 30.93 ABR)

ABR of spontaneous bleeds with HYMPAVZI:

35% image

lower than routine
prophylaxis

(3.78 ABR vs 5.86 ABR)

Secondary objective

Fewer total bleeds

ABR of total bleeds with HYMPAVZI:

85% image

lower than on-demand

(7.39 ABR vs 47.76 ABR)

ABR of total bleeds with HYMPAVZI:

32% image

lower than routine
prophylaxis

(5.97 ABR vs 8.84 ABR)

Before you start using HYMPAVZI, it is very important to talk to your doctor about using factor VIII and factor IX products while using HYMPAVZI.*
