Hemophilia A Clinical Trial in Sacramento, CA

About This Hemophilia A Study in Sacramento

WP44714 is a Phase I/II, open-label, non-randomized, global, multicenter trial consisting of two parts: * Part 1 is a multiple-ascending dose (MAD) study in adult and adolescent male participants with severe or moderate hemophilia A with or without factor VIII (FVIII) inhibitors. * Part 2 is a multiple-dose study in pediatric male participants with severe or moderate hemophilia A with or without FVIII inhibitors. The overall aim of the study is to investigate the safety, tolerability, pharmaco

Sponsor: Hoffmann-La Roche

Who Can Participate

Inclusion Criteria

Diagnosis of severe (Factor VIII \[FVIII\] coagulant activity \<1 IU/dL) or moderate (FVIII coagulant activity ≥1 IU/dL and ≤5 IU/dL) congenital hemophilia A with or without inhibitors against FVIII

Participants with FVIII inhibitors: participants using recombinant activated factor VII (rFVIIa) or willing to switch to rFVIIa as primary bypassing agent for the treatment of breakthrough bleeds, trauma, or procedures

Historic local FVIII inhibitor test results being available during screening to confirm any previous inhibitor history and current status

Participants who previously successfully completed immune tolerance induction (ITI) must have done so at least 5 years before screening and must have no evidence of inhibitor recurrence (permanent or temporary) since. FVIII tolerance defined as \<0.6 Bethesda unit (BU)/mL (\<1.0 BU/mL only for laboratories with an historical sensitivity cutoff for inhibitor detection of 1.0 BU/mL) and in vivo recovery \>66%

Documentation of number and type of bleeding episodes in the last 24 weeks prior to enrollment

Adequate hematologic function, defined as platelet count ≥100,000 cells/μL and hemoglobin ≥11 g/dL at the time of screening

Adequate hepatic function defined as total bilirubin ≤1.5× age-adapted upper limit of normal (ULN) (excluding Gilbert syndrome) and both aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3× age-adapted ULN at the time of screening, and no clinical signs or known laboratory/radiographic evidence consistent with cirrhosis. For patients with Gilbert syndrome, bilirubin should be \<4 mg/dL or 68.4 umol/L at the time of screening.

For Part 1 only: Adequate renal function, defined as serum creatinine ≤2.5× age-adapted ULN and calculated creatinine clearance ≥30 mL/min by Cockroft-Gault formula

For Part 2 only: Adequate renal function, defined as serum creatinine ≤1.5× age-adapted ULN. When the serum creatinine is ≥1.5× ULN, creatinine clearance by Bedside Schwartz formula must be \>70 mL/min/1.73m\^2.

Willingness and ability to comply with schedules visits, treatment plans, laboratory tests, and other study procedures

Exclusion Criteria

Inherited or acquired bleeding disorders other than congenital hemophilia A

Ongoing or planned ITI therapy

Previous or current treatment for thromboembolic disease (with the exception of previous catheter-associated thrombosis for which anti-thrombotic treatment is not currently ongoing) or signs of thromboembolic disease

At high risk for thrombotic microangiopathy (TMA), including past personal or family history of TMA, in the investigator's judgment

For Part 1 only: Personal history of ischemic heart disease, cerebrovascular disease, or diabetes mellitus

For Part 1 only: Strong family history of ischemic heart disease or cerebrovascular disease (i.e., first degree relatives such as parents, full siblings, or children): male relatives diagnosed under the age of 55 years and females under the age of 65 years

For Part 1 only: Previous or concomitant malignancies or leukemia

Other conditions (e.g., autoimmune conditions such as Systemic Lupus erythematosus and other systemic inflammatory disorders) that may currently increase the risk of bleeding or thrombosis

History of clinically significant allergies

Receipt of any of the following: i) An investigational drug to treat or reduce the risk of hemophilic bleeds within 5 half-lives of last drug administration or normalization of targeted parameters (e.g., anti-thrombin), whichever is longer; ii) A non-hemophilia-related investigational drug within last 30 days or 5 half-lives, whichever is shorter; iii) Any other investigational drug currently being administered or planned to be administered; iv) Prior gene therapy or gene therapy planned to be administered; v) Use of systemic immunomodulators (e.g., interferon or rituximab) at enrollment or planned use during the study, with the exception of anti-retroviral therapy to treat HIV.

Protein C activity, protein S free antigen, or anti-thrombin III activity levels below the lower limit of the reference range at screening

Known HIV infection with CD4 counts \<200 cells/μL

History of severe allergic or anaphylactic reactions to monoclonal antibody therapy and to chimeric or humanized antibodies or fusion proteins

Known hypersensitivity to Chinese hamster ovary cell products or to excipient content

History or presence of an abnormal ECG that is deemed clinically significant, (e.g., complete left bundle branch block, second- or third -degree atrioventricular heart block), including atrial fibrillation or evidence of prior myocardial infarction

QT interval corrected through use of Fridericia's formula (QTcF) \>450 ms demonstrated by at least two ECGs \>30 minutes apart

History of ventricular dysrhythmias or risk factors for ventricular dysrhythmias such as structural heart disease (e.g., severe left ventricular systolic dysfunction, left ventricular hypertrophy), coronary heart disease (symptomatic or with ischemia demonstrated by diagnostic testing), clinically significant electrolyte abnormalities (e.g., hypokalemia, hypomagnesemia, hypocalcemia), or family history of sudden unexplained death or long QT syndrome

Current treatment with medications that are well known to prolong the QT interval
