E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the safety of ADVATE based on serious adverse events (SAEs) [including FVIII inhibitors]. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the safety of ADVATE based on adverse events (AEs) and changes in laboratory parameters. • To assess the efficacy of prophylactic treatment with ADVATE. • To assess the efficacy of on-demand treatment with ADVATE in the control of bleeding episodes. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. The participant or legally authorised representative (in case of study participants <18 years of age) gave written informed consent to participate in the study. 2. Participant of any age with hemophilia A. 3. Participant defined as a previously treated patient (PTP): a. Participant aged >=6 years that has been previously treated with plasma-derived and/or recombinant FVIII concentrate(s) for a minimum of 150 exposure doses (EDs). b. Participant aged less than <6 years that has been previously treated with plasma-derived or recombinant FVIII concentrate(s) for a minimum of 50 EDs. 4. Participant as negative history of FVIII inhibitors and negative inhibitor at screening defined as less than 0.6 Bethesda units (BU) per millilitre (Nijmegen-modified Bethesda assay). 5. Participant is human immunodeficiency virus negative (HIV-); or human immunodeficiency virus positive (HIV+) with stable disease and cluster of differentiation 4 (CD4+) count >=200 cells per cubic millimetre (mm^3), as confirmed by central laboratory at screening. 6. Participant is hepatitis C virus negative (HCV-) by antibody or polymerase chain reaction (PCR) testing (if positive, anti-body titre will be confirmed by PCR), as confirmed by central laboratory at screening; or hepatitis C virus positive (HCV+) with chronic stable hepatitis. 7. Participant is willing and able to comply with the requirements of the protocol. |
|
E.4 | Principal exclusion criteria |
1. Participant has known hypersensitivity to mouse or hamster proteins or to any of the excipients of FVIII (factor VIII) concentrates. 2. Participant has been diagnosed with bleeding disorder(s) other than congenital hemophilia A, such as acquired hemophilia A, von Willebrand´s disease (VWD) or thrombocytopenia (platelet count <100,000 per millilitre). 3. Participant has received treatment for hemophilia A with non-FVIII products or concentrates (example, emicizumab [Hemlibra®]) in the 6 months prior to screening. 4. Participant has severe chronic hepatic dysfunction (example, >=5 times upper limit of normal alanine aminotransferase [ALT], aspartate aminotransferase [AST] or international normalised ratio [INR] >1.5 as confirmed by central laboratory at screening). 5. Participant has planned or is likely to have, surgery during the study period. 6. Participant has a clinically significant medical, psychiatric, or cognitive illness, or recreational drug or alcohol use that, in the opinion of the investigator, would affect participant's safety or compliance. 7. Participant currently receiving or is scheduled to receive during the course of the study, an immunomodulating drug (example, corticosteroid agents at a dose equivalent to hydrocortisone >10 milligram per day, or α-interferon) other than antiretroviral chemotherapy. 8. Participant has participated in another clinical study involving an investigational product (IP) or investigational device within 30 days prior to enrolment or is scheduled to participate in another clinical study involving an IP or investigational device during the course of this study. 9. Participant is a family member or employee of the investigator. |
