PROVEN EFFICACY

Annual rate of serious bacterial infections* in the extension study was 0.0214

DEMONSTRATED TOLERABILITY

97% of adverse reactions were non-serious in the pivotal trial, and 96% were non-serious in the extension trial†14

  • In the US pivotal phase III trial (n=80)15
    • The annual rate of serious bacterial infections* (SBI) was 0.08 and of other infections was 3.55
    • 97% of adverse reactions were non-serious, and 90% were rated mild or moderate in severity
  • In patients studied up to 29 months in the extension trial (n=55)14
    • The annual rate of SBI* was 0.02 and of other infections was 1.60
    • 96% of adverse reactions were non-serious, and 93% were rated mild or moderate in severity

*SBI were defined as pneumonia, bacleremia/septicemia, osteomyelitislseptic arthritis. bacterial meningitis, and visceral abscess.
1 patient had serious adverse reactions in the pivotal trial; 11 patients had serious adverse reactions in the extension trial.

PROVEN EFFICACY

Overall response rates to Privigen were 61% and 73% in PRIMA and PATH,* respectively

RAPID RESPONSE

Almost all who responded to Privigen did so after 1–2 maintenance treatments at Weeks 4 and 7*

DEMONSTRATED TOLERABILITY

In both studies,* 97% of adverse reactions were mild or moderate in intensity with 2 and 8 subjects experiencing serious adverse reactions in PRIMA and PATH, respectively

Largest CIDP Trial

PATH, one of two clinical trials,* was the largest ever CIDP study, evaluating 207 patients

Privigen improved strength in addition to functional ability

In PRIMA:

  • Privigen improved muscle strength as measured by Medical Research Council (MRC) sum score
    • Average improvement in MRC sum score was 6.9 points
    • A clinically meaningful improvement is defined as ≥3 points
  • Dominant hand grip strength improved by a mean of 14.1 kPa
    • Similar results were observed in the nondominant hand

In PATH:

  • Privigen improved muscle strength as measured by MRC sum score
    • Average improvement in MRC sum score was 3.6 points
    • A clinically meaningful improvement is defined as ≥3 points
  • Dominant hand grip strength improved by a mean of 12.2 kPa
    • Similar results were observed in the nondominant hand
*In a prospective, open-label, single-arm, multicenter clinical study (Privigen Impact on Mobility and Autonomy [PRIMA]), 28 subjects with CIDP received a Privigen loading dose of 2 g/kg followed by Privigen maintenance doses of 1 g/kg every 3 weeks for up to 21 weeks with 3-week follow-up. In a second prospective, open-label Privigen prerandomization phase of a multicenter clinical study (Polyneuropathy and Treatment with Hizentra [PATH]), 207 IVIg-pretreated subjects with CIDP received a Privigen loading dose of 2 g/kg followed by up to 4 Privigen maintenance doses of 1 g/kg every 3 weeks for up to 13 weeks.
Overall response rate was defined as percentage of subjects who experienced at least a 1-point decrease in adjusted INCAT score.
Serious adverse reactions included hemolysis (2), exacerbation of CIDP (2), acute rash, diastolic increased blood pressure, hypersensitivity, pulmonary embolism, respiratory failure, and migraine. A total of 4 patients discontinued treatment due to serious adverse reactions.

PROVEN EFFICACY

80.7% had a 150% platelet count increase within 7 days*12

RAPID RESPONSE

Mean platelet count rose above 50 x 109/L in 1 day*12

LONG LASTING

Duration of response was at least 8.8 days in 75% of patients*12

  • In the ITP clinical trial,* 80.7% of subjects (46 of 57) responded to Privigen with a 150% rise in platelet count within 7 days from ≤20 x 109/L to at least 50 x 109/L12
  • Platelet counts rose rapidly–the mean platelet count increased from 13 x 109/L to 52 x 109/L in only 1 day, before the second infusion12
  • Response was both quick and lasting–the duration of response was at least 8.8 days in 75% of patients12
  • Adverse events were generally mild or moderate12

* Study was performed on 57 subjects with chronic ITP. Each subject had a platelet count of ≤20 x 109/L. Dose was 1 g/kg on 2 consecutive days. Primary endpoint was elevation of platelet count to at least 50 x 109/L within 7 days of infusion.
