HYMPAVZI® (marstacimab-hncq) injection 150 mg/mL logo

For routine prophylaxis in patients 12 years and older with hemophilia A or B without inhibitors

Only HYMPAVZI is a once-weekly fixed-dose* pen with proven bleed protection and demonstrated safety

Why HYMPAVZI

The same dose comes in every pen, so you don't need to mix or measure

Once-weekly dosing designed to fit into your schedule

Injected under the skin, not into a vein

*Your first dose (loading dose) of HYMPAVZI is 300 mg (two 150 mg injections). Then you will inject a weekly (maintenance) dose consisting of 1 or 2 injections as prescribed by your healthcare provider. If more than 1 injection is required to deliver a complete dose, administer each injection at a different injection site.

92% reduction in treated bleeds on HYMPAVZI compared to on-demand factor-based treatment (3.20 annualized bleed rate [ABR] vs 39.86 ABR). 36% reduction in treated bleeds on HYMPAVZI compared to routine factor-based prophylaxis treatment (5.09 ABR vs 7.90 ABR).

In the BASIS Study, the most common adverse reactions included injection site reactions, headache, and pruritus.

§In the BASIS phase 3 study, the primary objective was to measure the annualized bleed rate (ABR) of treated bleeds vs on-demand factor-based treatment and vs factor-based prophylaxis after 12 months on HYMPAVZI. 92% reduction in treated bleeds on HYMPAVZI compared with on-demand factor-based treatment (3.18 ABR vs 38.00 ABR). 35% reduction in treated bleeds on HYMPAVZI compared with routine prophylaxis treatment (5.08 ABR vs 7.85 ABR). Secondary objectives measured the ABR of treated joint bleeds, treated target joint bleeds, treated spontaneous bleeds, and total bleeds (treated and untreated). 91% reduction in joint bleeds on HYMPAVZI compared with on-demand factor-based treatment (2.83 ABR vs 32.86 ABR). 27% reduction in joint bleeds on HYMPAVZI compared with routine prophylaxis treatment (4.13 ABR vs 5.66 ABR). 92% reduction in target joint bleeds on HYMPAVZI compared with on-demand factor-based treatment (1.84 ABR vs 23.18 ABR). 25% reduction in target joint bleeds on HYMPAVZI compared with routine prophylaxis treatment (2.51 ABR vs 3.36 ABR). 92% reduction in spontaneous bleeds on HYMPAVZI compared with on-demand factor-based treatment (2.44 vs 30.93 ABR). 35% reduction in spontaneous bleeds on HYMPAVZI compared with routine prophylaxis treatment (3.78 ABR vs 5.86). 85% reduction in total bleeds on HYMPAVZI compared with on-demand factor-based treatment (7.39 ABR vs 47.76 ABR). 32% reduction in total bleeds on HYMPAVZI compared with routine prophylaxis treatment (5.97 ABR vs 8.84 ABR). Individual results may vary.
