Kiovig Solution for Infusion 100mg/ml

INFUSION, SOLUTION

**Posology and method of administration** Replacement therapy should be initiated and monitored under a physician experienced in the treatment of immunodeficiency. **Posology** The dose and dosage regimen are dependent on the indication. In replacement therapy the dosage may need to be individualised for each patient depending on the pharmacokinetic and clinical response. The following dosage regimens are given as a guideline. Replacement therapy in primary immunodeficiency syndromes The dosage regimen should achieve a trough level of IgG (measured before the next infusion) of at least 4–6 g/l. Three to six months are required after the initiation of therapy for equilibration to occur. The recommended starting dose is 0.4–0.8 g/kg body weight (BW) followed by at least 0.2 g/kg BW every three weeks. The dose required to achieve a trough level of 6 g/l is of the order of 0.2–0.8 g/kg BW/month. The dosage interval when steady state has been reached varies from 2 to 4 weeks. Trough levels should be measured in order to adjust the dose and dosage interval. Replacement therapy in myeloma or chronic lymphocytic leukaemia (CLL) with severe secondary hypogamma-globulinaemia and recurrent infections; replacement therapy in children with congenital AIDS and recurrent infections The recommended dose is 0.2–0.4 g/kg BW every three to four weeks. Idiopathic Thrombocytopenic Purpura (ITP) For the treatment of an acute episode, 0.8–1 g/kg BW on day one, which may be repeated once within 3 days, or 0.4 g/kg BW daily for two to five days. The treatment can be repeated if a relapse occurs. Guillain Barré Syndrome 0.4 g/kg BW/day for 3 to 7 days. Experience in children is limited. Kawasaki Disease 1.6–2.0 g/kg BW should be administered in divided doses over two to five days or 2.0 g/kg BW as a single dose. Patients should receive concomitant treatment with acetylsalicylic acid. Multifocal Motor Neuropathy (MMN) Starting dose: 2 g/kg given over 2 – 5 days. Maintenance dose: 0.5 – 2.4 g/kg every month based on clinical response. Allogeneic Bone Marrow Transplantation Human normal immunoglobulin treatment can be used as part of the conditioning regimen and after the transplant. For the treatment of infections and prophylaxis of graft versus host disease, dosage is individually tailored. The starting dose is normally 0.5 g/kg BW/week, starting seven days before transplantation and for up to 3 months after transplantation. In case of persistent lack of antibody production, dosage of 0.5 g/kg BW/month is recommended until the antibody level returns to normal. The dosage recommendations are summarised in the following table:  **Method of administration** Human normal immunoglobulin should be infused intravenously at an initial rate of 0.5 ml/kg BW/hr for 30 minutes. If well tolerated, the rate of administration may gradually be increased to a maximum of 6 ml/kg BW/hr. Clinical data obtained from a limited number of patients also indicate that adult PID patients may tolerate an infusion rate of up to 8 ml/kg BW/hr. For further precautions for use see ‘Special warnings and precaution for use’ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_. In patients at risk for acute renal failure or thromboembolic adverse reactions, KIOVIG should not be infused rapidly. In general, it is recommended that patients beginning treatment with KIOVIG or switching from one intravenous immunoglobulin (IVIg) brand to KIOVIG be started at the lowest rate and then increased to the maximal rate if they have tolerated several infusions at intermediate rates of infusion. KIOVIG should only be administered intravenously. Other routes of administration have not been evaluated. Certain adverse reactions such as headaches and flushing may be related to the rate of infusion. Slowing or stopping the infusion usually allows the symptoms to disappear promptly. The infusion may then be resumed at a rate that does not result in recurrence of the symptoms. (See ‘Adverse Reactions’ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_) Adverse reactions may occur more frequently in immune deficient patients, who receive human normal immunoglobulin for the first time, when they switch from another IVIg brand, or when there has been a long interval since the previous infusion. (See ‘Adverse Reactions’ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_) KIOVIG is recommended for infusion at a concentration of 10%. If KIOVIG must be diluted, 5% glucose solution should be used as a diluent.
