Post Approval Observational Study to Learn More About How Safe Octocog Alfa is and How Well it Works in Patients With Severe Hemophilia A in India
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.

A Study to Learn About How Changing Therapy From Emicizumab to Marstacimab Affects People With the Severe Hemophilia A.
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.

A Study to Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Subcutaneous Emicizumab in Participants From Birth to 12 Months of Age With Hemophilia A Without Inhibitors
This is a Phase IIIb, multicenter, open-label, single-arm study of prophylactic emicizumab in previously untreated and minimally treated patients at study enrollment from birth to ≤12 months of age with severe hemophilia A (intrinsic factor VIII \[FVIII\] level \<1%) without FVIII inhibitors. The study is designed to evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of emicizumab administered at 3 milligrams per kilogram of body weight (mg/kg) once every 2 weeks (Q2W) for 52 weeks. After 1 year of treatment, participants will continue to receive emicizumab (1.5 mg/kg once every week \[QW\], 3 mg/kg Q2W or 6 mg/kg once every 4 weeks \[Q4W\]) over a 7-year long-term follow-up period under this study frame.

Palliative Care Needs of Children With Rare Diseases and Their Families
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.

A Study to Evaluate Overall Health, Physical Activity, and Joint Outcomes in Participants With Severe or Moderate Hemophilia A Without Factor VIII Inhibitors on Emicizumab Prophylaxis
Study MO42623 is a Phase IV, multicenter, open-label, three cohort study designed to evaluate the impact of emicizumab prophylaxis on overall health, physical activity, and joint outcomes in participants aged ≥13 and \<70 years with severe hemophilia A without factor VIII (FVIII) inhibitors or moderate hemophilia A without FVIII inhibitors who are receiving FVIII prophylaxis and who will start emicizumab treatment as part of this study.

Study of Efficacy and Safety of FRSW107 in Pediatric Patients With Severe Hemophilia A
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.
