Active clinical trials for "Hemophilia A"

The purpose of this study is to examine the safety, tolerability and the way the body handles various single and multiple doses of ARC19499 in patients with hemophilia.

The purpose of the study is to evaluate the safety, tolerability and effect on FIX antigen and activity levels of ascending doses of SB-FIX. SB-FIX is an intravenously delivered Zinc Finger Nuclease (ZFN) Therapeutic for genome editing. It inserts a correct copy of the Factor 9 gene into the albumin locus in hepatocytes with the goal of lifelong therapeutic production of the Factor IX clotting factor.

A Phase 1/2, open-label, dose-finding safety study of single ascending doses of DTX101 in adult males with moderate/severe to severe hemophilia B.

Hemophilia B is a bleeding disease in males due to very low levels of coagulation factor IX (FIX) in the blood. The current treatment is intravenous injection of FIX clotting factor concentrates, in response to bleeding. This study will focus on the severe, most common type of hemophilia B. This study plans to use a virus called adeno-associated virus (AAV), which in nature causes no disease, and can be engineered to deliver the human FIX gene (AAV8-hFIX19 vector) to liver cells, where FIX is normally made. This study will use the AAV8-hFIX19 vector.

This is a multicenter, multinational, prospective, single-arm, nonrandomized, open-label study, planned in of approximately 25 male participants with congenital hemophilia A who will receive their first (primary) immune tolerance induction (ITI) treatment with alphanate. The study consists of 2 phases: An ITI Treatment Phase in which all eligible participants will receive ITI treatment with alphanate for a period of up to 33 months. Upon confirmation of complete immune tolerization, participants will then enter a 12-month Prophylactic Phase. If, after 33 months of ITI, a participants has achieved partial immune tolerance, the participants will enter a 12-month Prophylactic Phase. A 12-month Prophylactic Phase for all participants who meet the criteria for complete or partial success to continue on a prophylactic dosing regimen of alphanate. Due to limited enrollment, this study was early terminated.

This is a multi-center randomized phase III clinical trial, the Inhibitor Eradication Trial, in which Eloctate ITI plus Emicizumab will be compared with Eloctate ITI alone to eradicate inhibitors in severe hemophilia A.

This is a clinical study to investigate how well Biostate works in treatment of male patients below the age of 12 years who have a clotting factor deficiency that is aggravated by the development of antibodies. The antibodies are directed against the clotting factor that is given for replacement therapy and usually make therapy unsuccessful. The treatment used in this study is called immune tolerance therapy.

In this study a modified virus called adeno-associated virus (AAV) will be used to transfer a normal gene for human clotting factor IX into patients with severe hemophilia B (AAV human Factor IX vector). Gene therapy is a very new medical technique being used in a number of clinical studies for diseases such as cancer and cystic fibrosis. At this time, the U.S. Food and Drug Administration has approved no gene transfer products for commercial use. To date, 8 subjects have received AAV vector in the muscle for a hemophilia B trial by intramuscular injection, and, to date, 6 subjects have been treated with AAV vector in the current hemophilia B liver trial. Eleven cystic fibrosis subjects have received AAV vector into their nasal sinuses or lungs to date. In this study, AAV human Factor IX vector will be injected into the liver using a catheter inserted into a large blood vessel (called the proper hepatic artery or the right hepatic artery).

Using anonymized patient data collected as part of the WAPPS-Hemo project to explore the sources of variability in individual pharmacokinetics (PK); use the sources of variability to improve the performance of the WAPPS-Hemo models through the addition of the predictors of PK variability as covariates.

A study to assess treatment with a new formulation of recombinant factor VIII reconstituted with liposomes (BAY79-4980) to evaluate whether a once-a-week treatment is safe and can prevent bleeds in subjects with severe haemophilia A.
