*Significantly lower (P<0.0001) than the threshold of 1.0 per patient-year which provides substantial evidence of efficacy.

Pneumonia was reported in a 78-year-old patient who had a specific antibody deficiency and allergic bronchopulmonary aspergillosis.

ASBI=Acute serious bacterial infection; CI=confidence interval.

North American (NA) clinical study1: CUVITRU was studied in 77 patients (≥2 years of age) with PI in a prospective, open-label, noncontrolled, multicenter clinical trial to determine the efficacy, safety, tolerability, and pharmacokinetics (PK). The primary outcome measure was the annualized rate of acute serious bacterial infections (ASBIs), which was evaluated in 74 patients. Median treatment duration was 380.5 days (range, 30-629 days).

Consistent IG levels between infusions vs IVIG

CUVITRU maintained lower peak IgG and higher trough IgG levels than IVIG1

*In the North American clinical study, pharmacokinetic (PK) parameters were evaluated in 60 patients ≥2 years of age with PI. Patients were administered intravenously at 3 to 4 week intervals with GAMMAGARD LIQUID® [Immune Globulin (Human)] 10% Solution and then switched to weekly subcutaneous CUVITRU infusions.

IVIG=intravenous immune globulin.

See section above for Study Design information.

CUVITRU can be dosed weekly to every other week and still maintain consistent IG levels2

A total of 2063 IgG concentrations from 102 evaluable patients enrolled in 2 prospective, open-label, noncontrolled, multicenter clinical studies to determine the efficacy, safety, tolerability, and PK of CUVITRU in patients ≥2 years of age with PI. IgG population PK was characterized by nonlinear mixed-effects modeling and validated using data splitting and a visual predictive check. IgG profiles were simulated for 1000 patients/interval treated with CUVITRU. A CUVITRU adjustment factor of 130% was used to simulate CUVITRU to IVIG AUC ratios for weekly or biweekly CUVITRU dosing intervals and a monthly IVIG 10% dosing interval.

CUVITRU® was shown to significantly improve patient quality of life vs IVIG in terms of convenience (TSQM-9*) and treatment interference (LQI*) 1

Hand with a check mark icon.

Convenience measured as3:

  • Ease of using the medication in its
    current form
  • Ease of planning when to use the
    medication each time
  • Convenience in taking the medication
    as instructed
Infusion bag icon.

Treatment interference measured as3:

  • Interference with social/family life
  • Time waiting
  • Treatment is worthwhile
  • Dependence on others
  • Freedom to take trips or move
  • Scheduled according to patient’s convenience

Other Results:

  • In the TSQM-9, there was no significant improvement in the perception of effectiveness and global satisfaction domains in either age group: 2 to 12 years and 13 years and older
  • In the LQI, the change reported in therapy-related problems and therapy setting domains across all age groups was not statistically significant
  • In other assessments, health-related quality of life differences between IVIG and SCIG treatment were not statistically significant

In the North American clinical study1:  Health-related quality of life was assessed using the Pediatric Quality of Life InventoryTM (PEDS-QL) questionnaire (pediatric subjects) or the self-administered SF-36 survey (adult subjects). Quality of life was analyzed separately for the age groups 2 to 4 and 5 to 7 years (PEDS- QL, observer: parent), 8 to 12 and 13 years (PEDS-QL, observer: subject) and 14 years and older (SF-36, observer: subject). Treatment Satisfaction Questionnaire for Medication (TSQM-9) and Life Quality Index (LQI) questionnaire were assessed in patients ages 2 to 12 years (observer: parent) and 13 years and older (observer: patient). Each was assessed in 3 domains: Effectiveness, Convenience, and Global Satisfaction for TSQM-9; and Treatment Interference, Therapy-Related Problems, and Therapy Settings for LQI.

*TSQM-9, P<0.001; LQI, P=0.008.

LQI=Life Quality Index; TSQM=Treatment Satisfaction Questionnaire for Medication.
