1 · What the graph read from it

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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundHereditary angioedema (HAE) is a chronic, unpredictable disease. Long-term prophylactic treatments that offer durable efficacy, safety, and convenience are required to assist patients in achieving complete disease control, per international guidelines. We report an interim analysis of an ongoing phase 3 (VANGUARD) open-label extension (OLE) study evaluating the long-term safety and efficacy of garadacimab for HAE prophylaxis.

methodsAdults and adolescents aged ≥12 years with HAE previously participating in phase 2 and pivotal phase 3 (VANGUARD) studies were rolled over to an OLE, alongside newly enrolled patients. Patients received garadacimab 200 mg subcutaneously, once monthly for ≥12 months. The primary endpoint was treatment-emergent adverse events (TEAEs) in patients with C1 inhibitor deficiency/dysfunction.

resultsAt data cut-off (February 13, 2023; N = 161), median (interquartile range) exposure was 13.8 months (11.9-16.3). For the primary endpoint, 133/159 patients experienced ≥1 TEAE (524 events), equivalent to 0.23 events/administration and 2.84 events/patient-year. Garadacimab-related TEAEs (13% of patients, 52 events) were most commonly injection-site reactions (ISRs). No deaths occurred. One patient discontinued treatment due to garadacimab-related moderate ISR. Most TEAEs were mild/moderate; three events were serious (COVID-19, two events; abdominal HAE attack, one event) and not garadacimab related. No abnormal bleeding, thromboembolic, severe hypersensitivity, or anaphylactic events were observed. Mean HAE attack rate decreased by 95% from the run-in period; 60% of patients were attack-free. Almost all patients (93%) rated their response to garadacimab as "good" or "excellent."

conclusionGaradacimab has a favorable safety profile suitable for long-term use and provides durable protection against HAE attacks.
