Phase 3
Completed
Conditions
Hepatitis B, Chronic
Interventions
Drug: Specific intravenous anti-hepatitis B immunoglobulin
Registration Number
NCT00838071
Lead Sponsor

Exclusion Criteria
  1. Presence of HBV DNA or HBeAg indicating virus replication.
  2. Patients with known allergies to some component of HB-IVIG, such as sorbitol (e.g. patients presenting intolerance to fructose).
  3. Patients with a known background of severe or frequent reactions to products derived from plasma.
  4. Patients presenting arterial hypertension that is not clinically controlled.
  5. Patients presenting a creatinine value >2 mg/dl, nephrotic syndrome or renal failure.
  6. Patients presenting anaemia (haemoglobin < 11 g/dl).
  7. Patients being treated with interferon.
  8. The patient suffers some acute or chronic medical condition that the investigator believes may interfere with the development or interpretation of the study.
  9. The patient is known to abuse of alcohol, opiates, psychotropic agents or other drugs or chemical substances; or has done so in the past 12 months.
  10. Pregnant women at the time of inclusion or that may be pregnant in the next 7 months or breast-feeding women.

  12. Possibility that the patient may be treated with other products containing immunoglobulins in a period of 7 months.
  13. Suspicion of conditions that may affect the patient's compliance, including an expected survival of less than 1 year.
  14. Any patient that does not have a frozen serum sample previous to the first study medication infusion.
  15. Patients with selective IgA deficiency.

Primary Outcome Measures
NameTimeMethod
To determine if after 4 months of continuous monthly administration of HB-IVIG Grifols, the anti-hepatitis B antibodies contained in the product reach levels considered as protective, and to assess if these levels are kept constant during 2 more months.At months 4, 5, and 6
Secondary Outcome Measures
NameTimeMethod
To determine various pharmacokinetic parameters after 6 administrations of HB-IVIG GrifolsAt months 1, 2, 3, 4, 5, and 6
To determine the incidence of recurrences during the treatmentAt months 1, 2, 3, 4, 5, and 6
To evaluate tolerance to the administration of HB-IVIG GrifolsAt months 1, 2, 3, 4, 5, and 6
To confirm the viral safety of the product supervising viral markersAt months 1, 2, 3, 4, 5, and 6
To determine the in vivo recovery of 6 consecutive doses of HB-IVIG Grifols and demonstrate that it remains constant for each dose.At months 1, 2, 3, 4, 5, and 6
