Haemophilia A

This study will test how different doses of study medicine (Inno8) work in the bodies of people with haemophilia A. The purpose of the study is to see if Inno8 is safe to use for people with haemophilia A. The study medicine is a new medicine that cannot yet be prescribed by doctors. The study will last for about 11 weeks.

The purpose of this study is to find out if denecimig is safe and effective for treating people who have acquired haemophilia A. Participants will be in this study for up to around 1 year and 5 months (73 week).

Hemophilia A is an inherited bleeding disorder caused by the absence or deficiency of coagulation factor VIII. The perioperative management of individuals with hemophilia A involves replacement therapies, typically through bolus or continuous infusions of Factor VIII, to ensure effective hemostatic control during surgery. Efanesoctocog alfa represents a significant advance in treatment. It is a highly engineered, VWF-independent, recombinant FVIII fusion molecule with an ultra-long half-life of 47 hours in adults and 40 hours in children. Efanesoctocog alfa is approved in the U.S. and Germany for adults and children with hemophilia A for multiple purposes: routine prophylaxis to reduce bleeding episodes, on-demand treatment of bleeding episodes, and perioperative management. Despite its approval, the precise optimal use of efanesoctocog alfa in the surgical setting remains underexplored. Further research is essential to define its specific benefits in surgery, thereby enhancing its clinical utility and informing treatment protocols. The objective of this cohort study is to collect clinical data on the surgical management of patients with hemophilia A treated with Altuvoct® in a real-world setting. Data collected will include surgical context (outpatient or inpatient), number of FVIII infusions during the perioperative period, length of hospital stay, postoperative date of return to usual prophylaxis, and factor VIII use. The results will be compared with those obtained using efmoroctocog (Elocta) in the ongoing CHALE study in France. The multicenter design is critical due to the rarity of hemophilia A, the diversity of surgical procedures, and the need to enroll a sufficient number of patients. The management of patients with hemophilia A during and after surgery is inherently multidisciplinary and requires careful coordination and adherence to numerous requirements. Given the variability in practice among centers, this study aims to support secondary harmonization of protocols and minimize intercenter variability. Such efforts are in line with the missions assigned to the National Reference Center for Hemophilia in France, coordinated by Pr Dargaud, and emphasize the importance of optimizing and standardizing care practices. A similar study is currently underway in France with efmoroctocog alfa (Elocta), which has already included over 155 procedures under real-world conditions. Using a similar case report form (CRF) for the present study will enable a direct comparison of surgical outcomes between extended half-life and ultra-extended half-life FVIII treatments, providing deeper insight into their respective roles in perioperative care. Additionally, this approach will highlight the added value of efanesoctocog alfa compared to existing therapies. Another key advantage of this research is the opportunity to compare outcomes in patients receiving combined therapy with efanesoctocog alfa and emicizumab. Since the ongoing CHALE study has already included patients treated with both efmoroctocog and emicizumab, this comparison will further enhance our understanding of combination treatment strategies.

International, post-authorisation non-interventional study to evaluate real-life effectiveness, safety and utilisation patterns of Octapharma's FVIII concentrates Nuwiq, Octanate, and Wilate in previously untreated and minimally treated severe haemophilia A patients in routine clinical practice.

This research program is initiated to evaluate and document data on the success of ITI in 300 haemophilia A patients with newly developed or already existing FVIII-inhibitors (also patients who might potentially have failed in earlier ITIs), which will be treated with ITI - preferably high-dose based on individualized product selection, in order to improve management of this potentially devastating complication of haemophilia treatment. In order to investigate the role of in vitro tests on individual ITI success rate in patients undergoing ITI, the inhibitor plasma samples can be assayed against different FVIII concentrates using the following in vitro tests: Batch selection, Thrombin generation assay (TGA), Thrombin Generation Test (TGT) to monitor FVIII efficacy, Epitope mapping,IgG Subclasses specific for FVIII, Immunogenotyping.

This is an Open Label, Uncontrolled Study to Evaluate the the Safety and Efficacy of SCT800 for Prophylaxis Treatment in Severe Previously Untreated Hemophilia Patients.

The aim of this study is to evaluate the prevalence of synovitis in adult patients with haemophilia A.
