AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people aged 12 and older with severe or moderate congenital hemophilia A who have no FVIII inhibitors and are already on FVIII prophylaxis.
- Age
- 12 years and older
- Sex
- All sexes can join.
- Disease stage
- Severe (FVIII:C <1 IU/dL) or moderate (FVIII:C between ≥1 IU/dL and ≤5 IU/dL) congenital hemophilia A without inhibitors against FVIII.
- Earlier treatment
- Must have been on FVIII prophylaxis before the study. Treatment details and bleeding episodes must be documented for at least the last 6 months before screening.
- Biomarker or test result
- No documented FVIII inhibitor (<0.6 BU/mL) in the last 3 years, and a negative inhibitor test within 12 months before enrollment. FVIII half-life ≥6 hours or FVIII recovery >66%.
Main reasons for not taking part
- Allergy or sensitivity to the study treatments or their components
- Use of systemic immunomodulators (for example interferon or rituximab) at enrollment or planned during the study, except anti-retroviral therapy for HIV
- Planned surgery during the study (minor procedures excluded)
- Clinically significant abnormal ECG, or prior heart attack
- History of ventricular dysrhythmias or risk factors such as structural or coronary heart disease

A Multicenter, Randomized, Open-Label, Phase III Clinical Trial to Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of NXT007 Prophylaxis Versus Factor VIII Prophylaxis in People With Hemophilia A Without Inhibitors
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of NXT007 prophylaxis compared with Factor VIII (FVIII) prophylaxis in participants with severe or moderate congenital hemophilia A without FVIII inhibitors. The study will include people aged ≥12 years old who have been on FVIII prophylaxis treatment prior to study entry.
Inclusion: Diagnosis of severe (FVIII:C <1 IU/dL [International Unit per decilitre]) or moderate (FVIII:C between ≥1 IU/dL and ≤5 IU/dL) congenital hemophilia A without inhibitors against FVIII; No documented inhibitor (i.e., <0.6 BU/mL [Bethesda unit per millilitre]), FVIII half-life ≥6 hours, or FVIII recovery >66% in the last 3 years prior to screening; Documented historical negative test for FVIII inhibitor (i.e., <0.6 BU/mL) within 12 months prior to enrollment; Documentation of the details of prophylactic and episodic FVIII treatment and of the number and type of bleeding episodes for at least the last 6 months prior to screening; Agreement to adhere to the contraception requirements (for potential participants with childbearing potential).
Exclusion: Planned surgery (excluding minor procedures such as non-molar tooth extraction, incision and drainage) during the study; 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) or ECG evidence or clinical history of prior myocardial infarction; Sensitivity to any of the study investigations, or components thereof, or drug or other allergy that, in the opinion of the investigator, contraindicates participation in the study; Use of systemic immunomodulators (e.g., interferon or rituximab) at the time of enrollment or planned use during the study, except for anti-retroviral therapy to treat HIV; 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); Refusal to accept plasma-derived and/or blood product transfusion support in an emergency scenario.
