Garadacimab, a preventive treatment candidate from CSL Behring, led to significant and clinically meaningful reductions in swelling attacks in patients with hereditary angioedema (HAE), according to published data from the Phase 3 VANGUARD clinical trial. The company expects to seek garadacimab’s approval from global health authorities later this…

The U.S. Food and Drug Administration (FDA) has extended the approval of Takhzyro (lanadelumab) to include children with hereditary angioedema (HAE) starting at age 2. Takhzyro, available to patients ages 12 and older in the U.S. since 2018, is now the only approved treatment to prevent HAE swelling…

Rates of prescriptions for Firazyr (icatibant), an on-demand treatment to control swelling episodes in people with hereditary angioedema (HAE), have increased in recent years, especially for women, according to a study from Sweden. While the finding could mean that more patients have poorly-controlled disease, more prescriptions for the…

A single injection of STAR-0215, an experimental treatment to prevent swelling attacks in people with hereditary angioedema (HAE), safely led to rapid and sustained inhibition of the kallikrein protein in healthy adults, according to preliminary data from a Phase 1a trial. “STAR-0215 has shown early proof of concept for…

A single dose of the extended-release formulation of PHA121 — an investigational molecule under development for the prevention and treatment of swelling attacks associated with hereditary angioedema (HAE) — led to sustained, therapeutic levels of the medication in the bloodstream of participants. That’s according to promising data from…

A single infusion of the investigational gene therapy NTLA-2002 was well tolerated at two different doses and reduced the number of swelling attacks in people with hereditary angioedema (HAE) by more than 90%, according to interim results from the Phase 1 portion of a Phase 1/2 trial. The…

Off-label prescription of certain medications indicated for hereditary angioedema (HAE) with C1 deficiency to people with other types of angioedema is common, a team of French researchers found. Fewer than 20% of prescriptions for these medications, namely Berinert, Cinryze, Ruconest (conestat alfa), and Firazyr…

A class of medications used to treat diabetes is associated with the occurrence of angioedema, particularly among older adults, a study has found. The use of these medications, called dipeptidyl peptidase-4 inhibitors (DPP-4Is), was linked to the condition in some groups even when patients were not also using a…

Swelling in the hands and feet, as well as elevated blood levels of eosinophils — a type of immune cell — led clinicians to diagnose a Japanese woman with non-episodic angioedema associated with eosinophilia (NEAE), as described in a case report. Distinguishing NEAE from similar conditions is important, the…

One person out of six treated with Ruconest (rhC1INH) for idiopathic non-histaminergic angioedema (InH-AAE) as part of an exploratory study showed a positive clinical response to the medication. The findings may mean that Ruconest is effective in a subset of InH-AAE patients, the researchers noted. The study, “…
