Hemophilia Clinical Trial in Los Angeles, CA

About This Hemophilia Study in Los Angeles

This is a parallel, Phase 3, two-arm, open-label study to evaluate the efficacy and safety of treatment with fitusiran prophylaxis administered to male pediatric participants (aged 1 to \<12 years) who have severe hemophilia A or B, with or without inhibitory antibodies to FVIII or FIX. Number of participants: Approximately 85 participants will be enrolled into the study: * Approximately 60 fitusiran-naïve participants with severe hemophilia A or B, with or without inhibitors (fitusiran-naïve arm), and * Approximately 25 participants with severe hemophilia A or B with inhibitors rolling over from the EFC15467\* dose confirmation study (roll-over arm). * Fitusiran has been investigated in the pediatric population in study EFC15467, which enrolled male participants aged 1 to \<12 years with hemophilia A or B with inhibitors to examine the safety and tolerability of fitusiran in the pediatric population. Participants will be enrolled into 1 of 2 arms: * Fitusiran-naïve: these participants have not previously received fitusiran, and they will undergo screening and study eligibility assessments. Once enrolled, they will go through a 24-week standard of care (SOC) period before starting fitusiran prophylaxis. * Roll-over participants from the EFC15467 study: only participants who are still on active treatment in study EFC15467 and consenting to study EFC17905 will be eligible to roll over. They will not need to undergo screening or further eligibility assessments. They will directly enroll into the fitusiran treatment period and continue treatment on their current fitusiran dose. The duration of fitusiran treatment will be up to 160 weeks for the fitusiran-naïve arm and up to 60 weeks for the roll-over arm.

Participant must be 1 to \<12 years of age at the time of enrollment.

Participants must have severe hemophilia A or B (FVIII \<1% or FIX ≤2%) as evidenced by a central laboratory measurement at screening or documented medical record evidence.

Participants must meet inhibitor or non-inhibitor status as defined below: Inhibitor: Requiring use of BPA for prophylaxis or BPA as on-demand therapy for any bleeding episodes for at least the last 3 months prior to screening, and meet one of the following Nijmegen-modified Bethesda assay results criteria:

Inhibitor titer of ≥0.6 BU/mL at screening, OR

Inhibitor titer of \<0.6 BU/mL at screening with medical record evidence of 2 consecutive titers ≥0.6 BU/mL, OR

Inhibitor titer of \<0.6 BU/mL at screening with medical record evidence of 1 inhibitor titer ≥0.6 BU/mL and a history of anamnestic response, or severe allergic reaction (eg, anaphylaxis) or nephrotic syndrome Non-inhibitor: Requiring use of clotting factor concentrates (CFCs) for prophylaxis or CFCs as on-demand therapy for any bleeding episodes for at least the last 3 months prior to screening, and meet each of the following criterion:

Nijmegen-modified Bethesda assay inhibitor titer of \<0.6 BU/mL at screening, AND

No use of BPA to treat bleeding episodes for at least the last 3 months prior to screening

Participants must have adequate peripheral venous access, as determined by the Investigator, to allow the blood draws required by the study protocol.

Presence of clinically significant liver disease.

History of antiphospholipid antibody syndrome.

History of arterial or venous thromboembolism, unrelated to an indwelling venous access

Any condition (eg, medical concern), which in the opinion of the Investigator, would make the participant unsuitable for dosing or which could interfere with the study compliance, the participant's safety and/or the participant's participation in the completion of the treatment period of the study.

History of multiple drug allergies or history of allergic reaction to an oligonucleotide or GalNAc.

Subjects with a central or peripheral indwelling catheter, with a history of venous access complications (such as infections, thrombosis) leading to hospitalization and/or systemic anticoagulation therapy in the last 12 months.

AT activity \<60% at screening, as determined by central laboratory analysis.

Co-existing thrombophilic disorder.

Presence of an active Hepatitis C virus infection

Presence of acute hepatitis A or Hepatitis E virus infection.

Presence of acute or chronic hepatitis B virus infection.

Platelet count ≤100 000/μL.
