Active clinical trials for "Angioedemas, Hereditary"

The study hypothesis is that treatment of Hereditary Angioedema at the time of prodromal symptoms will decrease morbidity associated with the disease

The main aims of this study are to learn how lanadelumab moves through a child's body and if the children have any medical problems from lanadelumab. Other aims are to learn if prophylactic treatment with lanadelumab reduces the number and severity of HAE attacks in children, how lanadelumab affects the child's body, and if the children develop antibodies to lanadelumab. The study doctors will treat acute HAE attacks according to their standard practice. Participants will receive lanadelumab for up to 52 weeks. When they start treatment, participants will visit their clinic every week for the first 4 weeks. Then, they will visit their clinic every 4 weeks during treatment.

The purpose of this study is to assess the efficacy and safety of subcutaneous administration of a liquid formulation of C1 esterase inhibitor for the prevention of angioedema attacks in adolescent and adult subjects with hereditary angioedema.

The aim of this study is to assess the long-term safety of C1-esterase inhibitor (C1-INH) in preventing hereditary angioedema (HAE) attacks when it is administered under the skin of subjects with HAE. The safety of participating subjects will be assessed for up to 54 weeks. The long-term efficacy of C1-INH will also be assessed. Each eligible subject will enter the treatment phase, wherein subjects will be randomized to treatment with either low- or medium-volume C1-INH. Subjects who have an insufficient treatment response during the study will be given an opportunity to undergo a dose increase. The study aims to enroll eligible subjects who completed study CSL830_3001 (NCT01912456). Subjects who did not participate in study CSL830_3001 may also participate, if eligible and if space permits. Subjects from the United States (US) who complete Treatment Period 2 will be allowed to participate in an Extension Period. During the Extension Period participating US subjects will continue to receive treatment with open-label CSL830 for up to an additional 88 weeks.

The purpose of this study is to determine whether BCX4161 given as a daily oral prophylactic treatment is safe and effective in reducing the number of acute attacks in patients with hereditary angioedema.

The primary objectives of the study are to evaluate the safety, tolerability, and efficacy of two doses of CINRYZE with recombinant human hyaluronidase (rHuPH20) administered by subcutaneous (SC) injection to prevent angioedema attacks.

The objective of this study is to evaluate the safety and tolerability of a single Subcutaneous (SC) dose of Ecallantide in children and adolescents with Hereditary Angioedema (HAE).

Primary Objective: To evaluate the efficacy of recombinant human C1 inhibitor (rhC1INH) in the prophylaxis of angioedema attacks in patients with HAE Secondary Objective: To evaluate the safety and immunogenicity of recombinant human C1 inhibitor (rhC1INH) in the prophylaxis of angioedema attacks in patients with HAE

The primary objective of this study is: assess the safety and tolerability of ecallantide in paediatric patients for acute attacks of HAE The secondary objectives are: evaluate the pharmacokinetic profile of ecallantide in paediatric patients treated for acute attacks of HAE assess the efficacy of ecallantide in paediatric patients treated for moderate to severe acute attacks of HAE

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.
