Eine Studie zur Bewertung der Wirksamkeit und Sicherheit der Faktor-IX-Gentherapie mit PF-06838435 bei erwachsenen Männern mit mittelschwerer bis schwerer Hämophilie B (BENEGENE-2)

2. November 2026 aktualisiert von: Pfizer

PHASE 3, OPEN-LABEL, SINGLE-ARM STUDY TO EVALUATE EFFICACY AND SAFETY OF FIX GENE TRANSFER WITH PF-06838435 (RAAV-SPARK100-HFIX-R338L) IN ADULT MALE PARTICIPANTS WITH MODERATELY SEVERE TO SEVERE HEMOPHILIA B (FIX:C ≤2%) (BENEGENE-2)

This study will evaluate the efficacy and safety of PF-06838435 (a gene therapy drug) in adult male participants with moderately severe to severe hemophilia B (participants that have a Factor IX circulating activity of 2% or less). The gene therapy is designed to introduce genetic material into cells to compensate for missing or non-functioning Factor IX. Eligible study participants will have completed a minimum 6 months of routine Factor IX prophylaxis therapy during the lead in study (C0371004). Participants will be dosed once (intravenously) and will be evaluated over the course of 6 years. The main objective of the study will evaluate the annualized bleeding rate [ABR] for participants treated with gene therapy versus standard of care (SOC) therapy (FIX prophylaxis replacement regimen).

Week 12 to Month 15
Change From Baseline in Joint Health as Measured by the Hemophilia Joint Health Score (HJHS) Instrument at Month 12
Zeitfenster: Baseline, Month 12

A qualified healthcare professional assessed six joints (left ankle, right ankle, left elbow, right elbow, left knee, right knee) scored from 0 to 20 based on: duration of swelling, muscle atrophy, crepitus, flexion loss, extension loss, instability, joint pain, and strength. Gait was scored (0 to 4) based on walking, stairs, running, hopping on one leg. Total score = sum of scores from all joints + gait score ranged from 0 to 124, with the higher the number equating to more severe joint damage.

Baseline, Month 12
Change From Baseline in Hemophilia Quality of Life (Haem A QoL) Physical Health Domain at Month 12
Zeitfenster: Baseline, Month 12

The Haem-A-QoL questionnaire contained 46 items with ten domains that assessed health in the following areas: Physical Health; Feelings; View of Self; Sports and Leisure; Work and School; Dealing with Haemophilia; Treatment; Future; Family Planning; and Partnership and Sexuality. The physical health domain was considered as the primary domain in this questionnaire, had a transformed score range from 0 to 100, with lower scores representing higher quality of life. In this Outcome Measure Physical Health domain scores of Haem A QoL are reported.

Baseline, Month 12
Change From Baseline in Hemophilia Activities List (HAL) Complex Lower Extremity Activities Component Score at Month 12
Zeitfenster: Baseline, Month 12

The HAL was a multiple domain measure of the impact of hemophilia on functional abilities in adults. The 7 domains of this instrument contained 42 items in total, as follows: lying/sitting/kneeling/standing; lower (leg) functioning; upper (arm) functioning; transportation; self-care; household tasks; and sports/leisure. Selected items from five of the domains were used to create three components: upper extremity; basic lower extremity; and complex lower extremity activities. The component score of "complex lower extremity activities" was the most important in this questionnaire, had a transformed score range from 0 to 100, higher values indicated less functional limitations in performing tasks.
