Brief Summary

This is an interventional, prospective, international, multicenter, single-arm, Phase 3, and sequential efficacy and safety study in adolescents and adults with congenital hemophilia A or B with inhibitors to factor VIII (FVIII) or factor IX (FIX) undergoing elective major surgical procedures.

Conditions

Eligibility Criteria

• Age: 12 Years - 65 Years
• Sex: male
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• Each patient must meet the following criteria to be enrolled in this study:
• be male with a diagnosis of congenital hemophilia A or B of any severity
• have one of the following:
• current positive inhibitor test BU ≥5 (as confirmed at screening by the institutional lab) or history of high-responding inhibitors (BU ≥5) not further successfully treated by Immune Tolerance Induction OR
• a condition precluding the use of FVIII or FIX products to treat or prevent bleeding such as a previous anamnestic response after exposure to factor concentrates or a previous failure to respond to FVIII or FIX concentrates
• be ≥12 years to ≤65 years of age on the day of informed consent
• be scheduled for an elective major surgical procedure as defined in the study protocol (see Table ''Definitions for the specific purpose of Study F7TG2202'')
• have Hb ≥ 12 g/dL
• be capable of understanding and willing to comply with the conditions of the protocol OR in the case of a patient under the age of legal majority, parent(s)/legal guardian(s) must be capable of understanding and willing to comply with the conditions of the protocol
• have read, understood, and provided written informed consent (patient or parent(s)/legal guardian(s) if the patient is minor according to local regulation) and, where applicable according to local regulation, patient's assent if the patient is minor -

You may not qualify if:

• Patients who meet any of the following criteria will be excluded from the study.
• have any coagulation disorder other than hemophilia A or B
• be immunosuppressed (i.e. the patient should not be receiving systemic immunosuppressive medication; CD4+ cell counts at screening should be \>200/μL)
• known intolerance to LR769 or any of its excipients
• currently receiving immune tolerance induction (ITI) therapy
• have a known or suspected allergy or hypersensitivity to rabbits or rabbit proteins
• have platelet count \<100,000/μL
• have received an investigational drug within 30 days or within 5 half-lives of that investigational drug, whichever is longer, of the planned first LR769 administration, or be expected to receive such drug during participation in this study. Patients who have received fitusiran in a clinical study may not participate in this clinical study for 6 months since the last dose and if they have an antithrombin III level not in the normal range at screening.
• for patients using emicizumab, have received during the last 6 months or currently receiving a maintenance dosing regimen of emicizumab different from the indicated one ± 10% of approved dose), i.e. different from 1.5 mg/kg once weekly (±10%), 3 mg/kg (±10%) every two weeks or 6 mg/kg (±10%) every four weeks
• for patients using emicizumab, currently be any plans, or notes in the patient's medical records that would suggest the need to increase or decrease emicizumab dosing due to antidrug antibodies (ADAs), reduced PK, or coagulation/safety-related issues (e.g. lack of response, or potential/actual thromboembolic concerns, etc)
• have a clinically relevant hepatic (aspartate aminotransferase \[AST\] and/or alanine aminotransferase \[ALT\] \>3 times the upper limit of normal \[ULN\]) and/or renal impairment (creatinine \>2 times the ULN)
• have a history of arterial and/or venous thromboembolic events (such as myocardial infarction, ischemic strokes, transient ischemic attacks, DVT, or PE) within 2 years prior to the planned first dose of LR769, uncontrolled arrhythmia, or current New York Heart Association (NYHA) functional classification score of stages II - IV
• have an active malignancy (those with non-melanoma skin cancer are allowed)
• have any life-threatening disease or other disease or condition which, according to the investigator's judgment, could imply a potential hazard to the patient, or interfere with the study participation or study outcome (e.g. chronic, unmanaged hepatitis infection)
• be using aspirin, non-steroidal anti-inflammatory drugs (NSAIDS), herbs, natural medications, or other drugs with platelet inhibitory properties within one week prior to surgery and for the duration of treatment with LR769
