NCT07446010
Hemophilia A is a genetic condition that makes it hard for blood to clot properly. This happens because the body does not have enough of a protein called Factor VIII, which helps stop bleeding. The main goal of treating someone with hemophilia is to stop and prevent bleeding by giving them the missing Factor VIII. This treatment can be given when a person starts bleeding (called on-demand treatment), or it can be given regularly to prevent bleeding (called prophylactic therapy). In India, most people with hemophilia A get treatment only when they have a bleeding episode, and only a few receive regular preventive treatment. Octocog alfa (also known as BAY 81-8973) is a modern, laboratory-made version of Factor VIII. It is made without using any human or animal materials and has special features that help it work better in the body. In India, Octocog alfa is approved for use in adults and children with hemophilia A to: * Treat and control bleeding episodes when they happen * Manage bleeding during surgery * Prevent bleeding by giving regular treatment The safety and effectiveness of Octocog alfa have been shown in several global studies. This new study is required by Indian health authorities to collect information about how safe Octocog alfa is and how well it works in people with hemophilia A who have already received treatment. The study will look at how Octocog alfa is used in real-life medical practice in India, including how doctors prescribe it, how patients use it, and what treatment results they have.
NCT06938542
The palliative care needs of family caregivers of children with rare diseases and their children are largely unmet, including the need for support to prepare for future medical decision making. This trial will test the FACE-Rare intervention to see if investigators can identify and meet those needs; and if FACE-Rare effects family caregivers' quality of life and child healthcare utilization. Finally, investigators will determine if the intersectionality of child-sex, family-race, Federal poverty level, and social connection influences family quality of life and child health care utilization longitudinally.

Recombinant factor VIII for the prevention of bleeding in patients with severe haemophilia A undergoing major surgery while receiving emicizumab prophylaxis
NCT06703606
The purpose of the study is to learn about safety, how the body processes marstacimab and how it works in patients with severe hemophilia A without inhibitors. Hemophilia A is rare bleeding disorder where the blood doesn't clot normally. This causes a person to bleed a lot, even from a small cut. These patients who are on emicizumab medicine for routine prophylaxis for at least 6 months, and desire to switch to marstacimab medicine. Inhibitors are antibodies that the immune system develops because it sees the infused clotting factor as a foreign substance that needs to be destroyed. Antibodies are proteins that eat up the activated factor before it has time to stop the bleeding. Prophylaxis are preventive medicines. This study is seeking for participants: * with severe Hemophilia A withouth inhibitors who are on emicizumab treatment for at least 6 months. * must be 12 to less than 75 years old * must have a body weight of at least 35 kilograms. The results from this study will serve as a guide to doctors and their hemophilia A patients who will change their medicines in the real-world clinical setting. Patients who can take part in the study will receive marstacimab medicine as weekly injections under the skin of 150 milligrams for 4 months. Study treatment with marstacimab will be initiated no earlier than 14 days after last dose of emicizumab. The study can last up to 6 months. The sponsor will provide marstacimab. Patients will continue their usual treatment with the infused clotting factor for their bleeds when taking part in the study. Roll-over into an optional study treatment extension period will be available to participants who wish to continue prophylaxis with marstacimab in countries where it is not commercially available.
NCT06136507
This study was divided into four stages: screening period, main trial period, extension period and follow-up period. In the main trial, both groups received FRSW107 prophylactic therapy. The recommended initial dose of prophylactic administration was 50 IU/kg, the dose range was 25 to 50 IU/kg, and the recommended frequency of administration was once every three days (Q3D). The dose range could be adjusted according to the patient's response. The main trial period was prophylaxis up to ≥50 exposure days (EDs) and ≥6 months. The investigator may adjust the dose according to the clinical efficacy of the subjects (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ valley according to the following principles. If necessary, the investigator may adjust the dosing interval according to the clinical efficacy of the subject (the occurrence of bleeding and its clinical manifestations) and the concentration of FⅧ. Investigators are advised to inform sponsors or their research partners when adjusting doses and dosing intervals during prophylaxis. After participants completed prophylaxis until ≥50EDs and ≥6 months, participants' willingness and investigator evaluation were used to decide whether to enter the extended trial. All subjects entering the extended phase continued with the original prophylactic regimen until 100EDs was dosed. During the main trial period and the extended preventive treatment period, if the subjects have breakthrough bleeding events requiring treatment, hemostatic treatment of breakthrough bleeding with investigational drugs can be performed. The researchers can refer to the treatment guidance for different degrees of bleeding in Table 6-1. Taking into account the subject's prophylactic dose, severity of bleeding, site and extent of bleeding, clinical status, and previous PK results (if any), the investigator determines the appropriate dose to administer (recommended dose range: 25 to 50 IU/kg) and dosing times until the investigator assessed significant control of bleeding episodes (e.g. reduction of pain and swelling) or return to pre-bleeding activity. If the bleeding episode stops, the subject will continue with the same dose and frequency of prophylactic medication as before the bleeding episode.

NCT05281185
Individualised pharmacokinetic (PK)-guided dosing of extended half-life (EHL) FVIII concentrates prophylaxis may reduce hemophilia A bleeding events than previous prophylactic regimen. Methods A single-centre prospective cohort study, the investigators recruited consecutive eligible patients aged 5-25 years with clinically severe haemophilia A (FVIII:C ≤3%), no inhibitor, on low-dose weight-based prophylaxis at King Chulalongkorn Memorial Hospital (KCMH) from July 2021 to February 2022. All of patients with clinically severe haemophilia A received low dose weight-based standard half-life FVIII concentrates replacement prophylaxis for ≥ 1 year prior to enrolment in the study. The data of annual bleeding rate (ABR), annual joint bleeding rate (AJBR), annual FVIII use (prophylactic and breakthrough bleeding dosing) in the last 6 months before the study and number of target joints were collected at the beginning of the study. Baseline variables, including age and weight, were recorded before performing the analyses using online medical device (www.mypkfit.com). Wash-out period for 72 hours, each participant subsequently received a dose of 20 IU/kg FVIII by intravenous injection. Blood samples were collected and the concentration of FVIII was measured two times at 3 h and 48 h or 72 h after injection by one-stage technique. Desired FVIII trough levels were selected in this study as 1%. Individually proper regimen were selected by discussion with patients and families. All of participant individually underwent dose calculation of EHL factor VIII concentrates and received low dose PK-guided regimen (10-20u/kg, 2-3times/week) with EHL FVIII concentrates for 6 months. If breakthrough bleeding occurs, FVIII concentrates 500 U intravenous injection immediately. ABR, AJBR, HJHS and annual FVIII concentrates use were again prospectively recorded during intervention period after PK adjustment for 6 months. Primary objectives To compare clinical outcomes including annual bleeding rate (ABR), annual joint bleeding rate (AJBR) and Haemophilia joint health score (HJHS) before and after switching from standard half-life (SHL) to Extended half-life (EHL) factor VIII concentrates with adjusted dosing by PK-guided program (MyPKFiT®) in severe haemophilia A patients Secondary objectives To compare factor VIII concentrates consumption before and after using PK-guided program (MyPKFiT®) adjusting dose of factor VIII infusion in severe HA patients.
