In a clinical study, Patients experienced 0.025 acute serious bacterial infections (ASBIs) per patient year. Here’s what that means:

HyQvia was studied in a clinical trial of 83 patients with primary immunodeficiency (PI), with the main goal of measuring how many ASBIs they experienced over the course of 1 year.

ASBIs are short-term but serious infections caused by bacteria that require immediate medical care. The FDA standard for efficacy—that is, if an immunoglobulin works—is less than 1 ASBI per year. In the clinical trial, people taking HyQvia experienced significantly less than that.


  • ASBIs included 2 cases of pneumonia that occurred during the 12 months after ramp-up (P<0.0001; upper 99% confidence limit, 0.046)
  • Both cases of pneumonia received outpatient treatment with oral antibiotics. During the ramp-up period, there was an additional case of pneumonia that required hospitalization

In a clinical study, Patients infusing HyQvia experienced 52% reduction of general (systemic) side effects (like fatigue and headache) compared to those on IVIG infusions.

The number of these general (systemic) side effects was 222 per 1,129 HyQvia infusions (a rate of 0.20) vs 154 per 365 IVIG infusions (a rate of 0.42).

The most common general (systemic) side effects were headache, antibody formation against hyaluronidase (Hy), fatigue, nausea, fever, and vomiting.

In people using HyQvia, the most common side effects at the infusion site (local) were pain, redness, swelling, and itching.
