Filter by:This trial is conducted globally. The aim of the trial is to investigate safety, efficacy and pharmacokinetics (the exposure of the trial drug in the body) of NNC 0129-0000-1003 (N8-GP) in children with severe haemophilia A who have undergone treatment with previous factor VIII (FVIII) products.
Investigate the inhibitor development rate of Human cl rhFVIII in previously untreated patients with severe Hemophilia A.
This study will assess the pharmacokinetics and pharmacodynamics of rhFVIIa at three dose levels. The results will help identify the most optimal doses to take forward to the Phase 2/3 studies where bleedings in hemophilia patients with inhibitors will be treated with rhFVIIa.
This study will examine viral dynamic responses in subjects with chronic hepatitis C and hemophilia when treated with pegylated interferon + ribavirin and telaprevir.
This trial is conducted in Europe. The aim of the trial is to investigate the pharmacokinetics (the exposure of the trial drug in the body) of four lots of turoctocog alfa (a human recombinant coagulation factor VIII (FVIII)) in subjects with haemophilia A.
This study will examine the pharmacokinetics, safety and efficacy of rIX-FP for the control and prevention of bleeding episodes in children who have previously received factor replacement therapy for hemophilia B.
This is a single dose, open-label, randomized, crossover study in subjects with severe Hemophilia A to compare the bioavailability of 2 different strengths of Kogenate FS (BAY 14-2222).
Hemophilia A is a congenital bleeding disorder caused by deficiency of factor VIII (FVIII) and is treated by replacement therapy with FVIII concentrate. Approximately 30% of people with severe hemophilia A develop neutralizing antibodies, called FVIII inhibitors, which interfere with the function of FVIII concentrates. The reason that some, but not all, people with severe hemophilia A develop inhibitors is incompletely understood. Understanding individual and environmental risk factors is important to be able to prevent and possibly treat inhibitors. This study will look at individual and treatment characteristics in babies with severe hemophilia A who have not yet received treatment with FVIII (called Previously Untreated Patients, or PUPS). Subjects in the study will be asked to provide diaries of treatments, medications, and illnesses. Treatment will be directed by the subjects' physician, but all subjects will receive Advate, a third-generation recombinant FVIII product. Subjects will have blood drawn for laboratory tests, which include studies of the immune system and genetic studies of the FVIII mutation, before and 7-9 days after the first treatment with FVIII, and 5 days (+/-2 days) after the 5th, 10th, 20th, 30th, 40th, and 50th days of treatment with FVIII (exposure days). The duration of the study will be first 50 treatments or 3 years, whichever comes first.
Haemophilia is a disorder, usually genetic, affecting mostly male individuals, in which one of the proteins needed to form blood clots (FVIII) is missing or not present in sufficient levels. In a person with haemophilia, the clotting process is much slower and the person experiences bleeding episodes that can result in serious problems and potential disability. The current haemophilia standard of care is to maintain FVIII activity level above 1%. Sometimes, patients can develop antibodies (so called "inhibitors") against FVIII and it is no longer effective at controlling bleeds. Bleeds in these patients are currently treated using other proteins involved in the clotting process. The purpose of this study is to investigate how effectively BAY86-6150 may stop acute bleeds in "inhibitor" patients. This study consists of two parts, A and B. The purpose of part A is to find the most effective yet tolerable out of four doses of BAY86-6150 with regard to efficacy and safety (dose-finding part). Part A is expected to last 9 - 29 months. The purpose of part B is to confirm efficacy and safety of the dose found in part A in all participating patients (confirmatory part). Part B is expected to last 12-32 months. Approximately 60 male subjects 12 to 62 years-of-age with moderate or severe haemophilia A or B, with inhibitors to FVIII or FIX, who have had 4 or more bleeding episodes in the last 6 months, will participate in this study. Patient's bleeds will be treated with BAY86-6150 and with a rescue medication if no response is made to BAY86-6150. Patients will attend the treatment centre at regular intervals and be required to keep an electronic diary.
The objectives of this study are to assess the tolerability and safety after single dose treatments of BAX 855 in previously treated patients (PTPs) with severe hemophilia A, to determine the pharmacokinetic (PK) parameters of BAX 855 compared in crossover with ADVATE, and to evaluate the impact of anti-polyethylene glycol (PEG) antibodies on PK parameters.
