Switching Long-Term Prophylaxis to Donidalorsen for Hereditary Angioedema: 1-Year OASISplus Results.
Article in Allergy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05392114 (An Open-Label, Long Term Safety and Efficacy Study of Donidalorsen in the Prophylactic Treatment of Hereditary Angioedema), which is not on this map.

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.

Abstract
backgroundDonidalorsen is an antisense oligonucleotide designed to reduce plasma prekallikrein in patients with hereditary angioedema (HAE). The Switch cohort of the OASISplus study (NCT05392114) evaluated the long-term safety and efficacy of donidalorsen in patients who switched from a long-term prophylactic treatment (LTP) to donidalorsen with 1-year outcomes.
methodsThis study enrolled patients with HAE aged ≥ 12 years previously on stable doses of an LTP (lanadelumab, berotralstat, C1 inhibitor). Patients directly switched from an LTP to donidalorsen 80 mg administered subcutaneously once every 4 weeks. Endpoints included incidence and severity of treatment-emergent adverse events (TEAEs; primary endpoint), monthly HAE attack rate, Angioedema Quality of Life (AE-QoL), and Angioedema Control Test (AECT) measured at baseline and Week 52.
resultsSixty-five patients enrolled, and 54 (83.1%) completed 1 year. Eleven (16.9%) patients discontinued treatment during the first year, and one discontinued treatment after 1 year. Donidalorsen reduced HAE attack rates from baseline on the prior LTP by 67.6% over 52 weeks. Fifty-six of 64 (87.5%) dosed patients experienced a TEAE; most reported mild to moderate events. The most common treatment-related TEAEs were injection-site erythema (10.9%) and injection-site pruritus (10.9%). One patient had a serious adverse event that was not treatment-related. AE-QoL total score improved by 12.2 points (clinically meaningful ≥ 6 points) from baseline to Week 52, and 90.4% of patients had well-controlled disease (AECT ≥ 10) at Week 52.
conclusionIn patients who switched from another LTP, donidalorsen was well tolerated and improved long-term HAE attack rates, quality of life, and disease control.
