Active clinical trials for "Hemophilia A"

This study is to test whether the study drug (OBI-1) is safe and effective for the treatment of serious bleeding episodes in people with congenital hemophilia A.

The Study's Primary Objective is to evaluate the pharmacokinetics, safety (acute effects associated with infusions, and inhibitor development) and efficacy (breakthrough bleeding and control of hemorrhaging during prophylaxis) of IB1001 in previously treated pediatric subjects with hemophilia B.

The purpose of this pilot R34 trial is to determine the feasibility of a large single dose Phase III study of hemophilia adult prophylaxis comparing once weekly with thrice-weekly recombinant factor VIII. Efficacy will measured by bleeding frequency, factor usage, joint range of motion, cost, quality-of-life, F.VIII level, and inter-dose hypocoagulability by thrombin generation. Safety will be measured by inhibitor formation and bleeding events unresponsive to up to two rescue doses.

The purpose of this study is to evaluate the safety and dose escalation of SHP648 an adeno-associated viral vector for gene transfer in hemophilia B participants.

This is a real-world study of the safety of the treatments used for people with hemophilia. The study will follow people with hemophilia A or B from across the country for about 4 years as they receive treatment. The hemophilia treatment center (HTC) physician and participant will decide on the FDA-approved treatment to be used which may include non-factor products, bypassing agents, or clotting factor replacement products. The goal of this research is to study the use of hemophilia treatment products and their outcomes.

Severe haemophilia B (HB) is a bleeding disorder where a protein made by the body to help make blood clot is either partly or completely missing. This protein is called a clotting factor; with severe HB, levels of clotting Factor IX (nine; FIX) are very low and affected individuals can suffer life threatening bleeding episodes. HB mainly affects boys and men (approximately one in every 30,000 males). Current treatment for HB involves intravenous infusions of FIX as regular treatment (prophylaxis) or 'on demand' treatment. On demand treatment is highly effective at stopping bleeding but cannot fully reverse long-term damage that follows after a bleed. Regular treatment can prevent bleeding; however it is invasive for patients and also expensive. This clinical study aims to investigate the long-term safety and durability of FIX activity in participants who have been dosed with a new gene therapy product (FLT180a) in earlier clinical studies. Following administration, FLT180a results in production of FIX in the participants' liver cells which is then released into the blood stream. The aim is to have the participants' own body produce levels of FIX that allow for clotting to occur as normal as would be seen in a non-HB individual. This would remove the need for prophylaxis or on demand treatment following just a single administration of FLT180a. Up to 50 participants who have already been administered with FLT180a in the EU and US will take part in this study. Participants will be followed up in this trial until they have reached 15 years after being dosed. Participants will undergo procedures including physical examinations, join assessments, blood tests and liver ultrasounds. Participants will also need to complete a diary to document occurrence of bleeding episodes and record the amount of Factor IX concentrate they receive. Patient reports outcomes including measures of Quality of Life, disability and physical activity will also be collected.

The objective in this study is collecting post-marketing information on the safety and efficacy of Kovaltry under the routine clinical practice.

The primary goal of the INITIATE trial is to compare the clinical outcome of individualized lot selection to random lot selection utilizing one plasma-derived von Willebrand factor (VWF)/coagulation factor (FVIII) complex concentrate for immune tolerance induction (ITI) in subjects with congenital Hemophilia A, FVIII activity ≤2%, and a historical high-titer inhibitor [≥5 Bethesda Unit (BU)].

The study will be investigating safety in patients who switch to ReFacto AF from ReFacto and other Factor VIII products.

This study is about a factor VIII medicine called Adynovate (TAK-660) used during surgery for people with hemophilia A who have low blood levels of factor VIII. The aims of this study are as follows: To check for side effects from TAK-660. To check how well TAK-660 controls bleeding when used routinely during surgery and other invasive procedures such as tooth extractions. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. During the study, participants will receive infusions of TAK-660 during their hospital stay for surgery according to their clinic's standard practice. The study doctors will check for bleeds and side effects from TAK-660 from surgery until discharge.
