Active clinical trials for "Hemophilia A"

The purpose of this study is to evaluate whether IMMUNATE S/D is effective and safe in the treatment of hemophilia A patients. The study consists of 3 parts: Part 1 is a pharmacokinetic comparison of IMMUNATE S/D and its predecessor IMMUNATE. Part 2 is an evaluation of efficacy and safety of IMMUNATE S/D. Part 3 is a pharmacokinetic study of IMMUNATE S/D.

The purpose of this study is to determine how female hemophilia A carriers respond to a medication called DDAVP (Desmopressin).

This study is a multi-center, open-label, single-arm trial to evaluate the efficacy,safety and pharmacokinetics of SCT800 in regular prophylaxis and perioperative treatment in patients (≥12 years old) with severe hemophilia A who have been previously treated with coagulation factor VIII(FVIII:C) . This study includes two phases: the screening period and prophylaxis period.Prophylaxis with 25 - 50 IU/kg of SCT800 shall be administered once every other day or three times per week starting from V1 and prophylaxis with SCT800 shall continue for 24 consecutive weeks.

The purpose of this study is to assess efficacy, safety and pharmacokinetics of ADVATE in the treatment and prevention of bleeding episodes (BEs)

To continue the evaluation of the safety and efficacy of BAX 855 for prophylaxis and treatment of bleeding episodes in adult and pediatric previously treated patients (PTPs) aged ≤ 75 years of age with severe hemophilia A.

Study will look at baseline Vitamin D levels, calcium, albumin, liver enzymes, testosterone, osteocalcin, urine N telopeptides, bone mineral density, nutritional assessment and physical activity assessment of boys with hemophilia A or B (ages 2-20 yrs). Patients with low vitamin D levels will receive therapeutic doses of Vitamin D. At end of one year follow up studies will be repeated.

This study is designed to evaluate BeneFIX infused as prophylaxis regimens, compared with BeneFIX administered as an on-demand regimen only. In the trial, subjects will participate in 4 study periods. The first period is a 16-week on-demand treatment, during which subjects will utilize BeneFIX to treat bleeding events episodically only as they occur (i.e., on-demand treatment). At the end of this period, subjects will be randomly assigned to 1 of 2 BeneFIX prophylaxis regimens: either 100 IU/kg once weekly or 50 IU/kg twice weekly, and followed for 16 weeks. At the end of this period, subjects will use on-demand treatment for 8 weeks. The purpose of this 8-week period is to mitigate the potential carry-over effect of the prior prophylaxis regimen on bleeding frequency. Following this 8-week on-demand treatment, subjects will cross-over and receive the alternate study prophylactic regimen for 16 weeks. The primary endpoint is annualized number of bleeding episodes, compared between the first on-demand period and each of the prophylaxis regimens. A comparison of annualized bleeding episodes between the two prophylaxis regimens will also be performed. Subject-reported outcomes will also be collected using a patient diary. At 24 and 48 hours following the onset of each joint bleeding episode, information on pain, sleep, and work will be collected. Additional data on physical functioning will be recorded on the diary at the end of the 16-week on-demand period, and at the end of each prophylaxis period. Information on safety will also be collected. Each subject will participate in this study for approximately 59 weeks (15 months), including a screening period of up to 3 weeks, an initial 16-week on-demand period, two prophylaxis treatment periods of 16 weeks each, separated by an 8-week on-demand treatment period. A modified FIX recovery study will be performed once during each prophylaxis period. The study diary will also be used by subjects to collect secondary endpoints. These endpoints, which are subject-reported outcomes, will be recorded in the diary at 24 and 48 hours following the onset of each joint bleeding episode. Additional data on physical functioning will be recorded on the diary at the end of the 16-week on-demand period, and at the end of each prophylaxis period. Patients will be recruited in the United States, Canada, Europe and Russia.

Primary efficacy endpoint: To study whether there is a difference in the length of the bleeding free periods between infusion of FVIII that is reconstituted with 22.1, 12.6, or 4.2 mg of pegylated liposomes per kg bwt compared with standard formulation. Safety endpoint: To study the safety and tolerability of Kogenate FS reconstituted with Pegylated liposomes

The purpose of this study is to assess the safety and tolerability of MG1113 in the single ascending dose study (IV injection or SC injection) in healthy subjects and hemophiia patients.

This study will determine the efficacy of human-cl rhFVIII in previously treated patients with severe hemophilia A during prophylactic treatment, treatment of bleeding episodes and in surgical prophylaxis.
