Kinetics, Efficacy and Safety of C1-Esteraseremmer-N
Pharmacokinetics, Clinical Efficacy and Safety of C1 Inhibitor Concentrate (C1-Esteraseremmer-N) for the Treatment of Hereditary (and Acquired) Angioedema
A multicentre study to investigate pharmacokinetics, clinical efficacy and safety of nanofiltered Cetor® (called C1-esteraseremmer-N during the development phase) for the treatment of hereditary angioedema (HAE) will be performed. This study KB2003.01 consists of three parts, part A pharmacokinetics (phase II), part B treatment of attacks of angioedema (phase III) and part C prophylactic use of C1 inhibitor (phase III). Part B + C will provide data on the efficacy of C1-esteraseremmer-N.
The changes in the manufacturing process of C1-esteraseremmer-N, compared to Cetor® (the currently marketed C1-inhibitor product), nanofiltration and omission of hepatitis B immunoglobulin, most likely will not affect tolerability. The nanofiltration will provide more safety regarding viruses.
In part A, the pharmacokinetics of C1-esteraseremmer-N in patients with hereditary angioedema will be compared with the current registered product, Cetor®, in a randomised, blinded cross-over design. This study has to provide evidence that changes in the manufacturing process have not affected pharmacokinetics. In addition, this study provides data on safety of C1-esteraseremmer-N.

In part A, the pharmacokinetics of C1-esteraseremmer-N in patients with hereditary angioedema will be compared with the current registered product, Cetor®, in a randomised, blinded cross-over design. This study has to provide evidence that changes in the manufacturing process have not affected pharmacokinetics. In addition, this study provides data on safety of C1-esteraseremmer-N. Twelve HAE patients without signs of an attack will receive an administration of 1,000 U, 1,500 U or 2,000 U of C1-esteraseremmer-N or Cetor® and later on the same dose of the other product. Both antigenic and functional C1 inhibitor levels will be determined. Laboratory safety parameters and adverse events will be monitored as well
