Safety and Efficacy of Damoctocog Alfa Pegol in Previously Treated Children Aged 7 to < 12 Years With Severe Haemophilia A in the Phase 3, Open Label Alfa-PROTECT Main Study.
Trial report in European journal of haematology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it

Abstract
backgroundIn the earlier PROTECT VIII Kids study (NCT01775618), damoctocog alfa pegol was efficacious for prevention and treatment of bleeds in children aged < 12 years with severe haemophilia A.
objectiveAssess the safety of damoctocog alfa pegol, including hypersensitivity and loss of efficacy (LoE) due to an immune response to polyethylene glycol, in children aged 7 to < 12 years with severe haemophilia A.
methodsAlfa-PROTECT is a phase 3, multicentre, open-label, single-arm study (NCT05147662). Primary endpoint was the incidence of adverse events of special interest (AESI) leading to discontinuation during the first 4 exposure days.
resultsOverall, 35 children enrolled; 32 completed the 6-month study, 21 (60%) reported ≥ 1 AE. Median (range) treatment duration was 182 (172-198) days. All AEs were mild/moderate; 3/35 children (8.6%) had study drug-related AEs. One (2.9%) LoE event was considered an AESI, and led to temporary treatment interruption. No AEs resulted in study drug discontinuation. The probability of < 5% of patients experiencing an AESI was 92.2%. Bleed protection was maintained with damoctocog alfa pegol prophylaxis.
conclusionsThese data confirm the safety profile of damoctocog alfa pegol in children aged 7 to < 12 years with severe haemophilia A. Secondary endpoints indicate treatment was efficacious.
