The goal of this multicenter, two-stage, open-label study is to investigate the safety, immunogenicity, and efficacy of ANB-002 in subjects with hemophilia В. The study will have a dose-escalation design with elements of phase I/II seamless adaptive design.
The study design includes ANB-002 dose escalation in at three cohorts. In Cohort 1, the subject is treated with a single dose of ANB-002 (dose 1) administered as an intravenous infusion. Follow-up for the assessment of dose-limiting toxicity (DLT) will be carried out for 28 days. If no DLT events are observed in the subject of Cohort 1, the following subjects will be included in Cohort 1.
In Cohort 2, the subjects are treated with a single dose of ANB-002 (dose 2). In Cohort 3, the subject are treated with a single dose of ANB-002 (dose 3).
The decision to continue enrolling in cohorts will be made at the Independent Data Monitoring Committee (IDMC) meeting. After the IDMC makes a decision regarding the dosing subjects, further enrolment to the cohort will be carried out.
Based on the data from the follow-up period of subjects included in Сohorts 1-3, a potential therapeutic dose for further study will be determined and additional patients will be included to recieve this dose.
In exploratory Cohort 4 patients with anti-AAV5 antibodies and/or hepatitis B in anamnesis will be included. These subjects will recieve the dose 3 of ANB-002.
The total duration of participation of one subjects in the study will be 5 years.
292 studies on the registry are indexed under Hemophilia B; 51 are open to participants now.
This study's planned enrollment of 28 is close to the median of 26 across 171 interventional studies indexed under Hemophilia B.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Subjects in Cohort 1 will receive ANB-002 (arvenacogene sanparvovec) at a dose 1. Follow-up for the assessment of dose-limiting toxicity (DLT) will be carried out for 28 days. If no DLT events are observed in the subject of Cohort 1, the following subjects will be included in Cohort 1.
Genetic: ANB-002, dose 1
Subjects in Cohort 2 will receive ANB-002 (arvenacogene sanparvovec) at a dose 2. The decision to continue enrolling in Cohort 1 or dosing in Cohort 2 will be made at the IDMC meeting. After the IDMC makes a decision regarding the dosing in Cohort 2 subjects, the next subject will be included in Cohort 2. If no DLT events are observed in the subject of Cohort 2, the following subjects will be included in Cohort 2.
Genetic: ANB-002, dose 2
Subjects in Cohort 3 will receive ANB-002 (arvenacogene sanparvovec) at a dose 3. The decision to continue enrolling in Cohort 2 or dosing in Cohort 3 will be made at the IDMC meeting.
Genetic: ANB-002, dose 3
Exploratory cohort. Subjects in Cohort 4 (with anti-AAV5 antibodies and/or hepatitis B in anamnesis) will receive ANB-002 (arvenacogene sanparvovec) at the dose 3.

Changes in Haemo-A-QoL (Hemophilia-Specific Quality of Life) scores from baseline
Haemo-A-QoL is a quality of life (QoL) assessment instrument for patients with haemophilia, including the domains of consequences of bleeding, emotional impact, physical functioning, role functioning, treatment concern, and worry. Using scale overall score ranges from 0 to 100.The high score represent low quality of life.

Changes in EuroQol-5D-3L (European Quality of Life Questionnaire) scores from baseline
The EQ-5D-5L descriptive system of health-related QoL states consists of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). The EQ-5D-5L VAS overall score ranges from 0 to 100. A higher score is considered to be more favorable.
Time frame: 5 years
Changes in SF-36 (Short Form-36) scores from baseline
SF-36 is a questionnaire for evaluating health-related QoL (Quality of Life). The 36 questions are meant to reflect 8 domains of health, including physical functioning, physical role, pain, general health, vitality, social function, emotional role, and mental health. SF-3 overall score ranges from 0 to 100. The lower the score the more disability.

Evaluation of the condition of joints based on the Hemophilia Joint Health Score (HJHS)
Hemophilia Joint Health Score (HJHS) is the assessment system of joints in patients with haemophilia. Each joint (knee, elbow and ankle) receives a numeric score, which can be compared to itself over time to determine whether a joint is showing degeneration. The maximum score for an individual index joint is 20. Gait is scored 0 to 4. The maximum HJHS total score is 124, with a higher score indicating worse joint health.
Time frame: 5 years
Started May 2023 (actual). Primary completion is estimated for Nov 2025, 30 months after the start.
