Following a clinical hold last October of Intellia Therapeutics Inc.’s Magnitude and Magnitude-2 phase III trials of CRISPR/Cas9 gene editing therapy nexiguran ziclumeran (nex-z) to treat transthyretin amyloidosis with cardiomyopathy (ATTR-CM) and polyneuropathy (ATTR-PN), respectively, the U.S. FDA lifted the hold on Magnitude-2, pushing the company’s shares up by 22% in early trading Jan. 27.

Pharvaris NV looks to start filing marketing applications in the first half of 2026 on the back of positive phase III data showing oral bradykinin B2 receptor antagonist deucrictibant hit all primary and secondary endpoints as an on-demand treatment for hereditary angioedema (HAE) attacks.

Biocryst Pharmaceuticals Inc.’s near-term dilution should “pave the way for entrenchment” in the hereditary angioedema (HAE) space, thanks to the buyout of Astria Therapeutics Inc., RBC analyst Brian Abrahams said.

In Ionis Pharmaceuticals Inc.’s second U.S. FDA approval in under a year, the agency approved Dawnzera (donidalorsen) as a prophylactic therapy in the rare and genetic disease hereditary angioedema (HAE). The approval came as scheduled as the NDA had a PDUFA date of Aug. 21. Dawnzera now joins a market with previously approved drugs for the rare, genetic, life-threatening condition, as well as other companies with HAE drugs in development.

After delaying a June PDUFA date, the U.S. FDA has approved Kalvista Pharmaceuticals Inc.’s Ekterly (sebetralstat) for hereditary angioedema (HAE) in those aged 12 and older. The plasma kallikrein inhibitor now joins a market with previously approved drugs for the rare, genetic, life-threatening condition, as well as other companies with HAE drugs in development. Ekterly is the first orally-delivered on-demand treatment, as all others in the U.S. are intravenously or subcutaneously administered.

The U.S. FDA clearance June 16 of CSL Behring LLC’s humanized anti-factor XIIa monoclonal antibody garadacimab (CSL-312) to prevent hereditary angioedema (HAE) attacks juiced up the space in which – although other therapies are available as well – developers continue working on new prospects.

Following a complete response letter issued last October over CMC issues, CSL Behring LLC gained U.S. FDA approval June 16 of its humanized anti-factor XIIa monoclonal antibody, garadacimab (CSL-312), to prevent hereditary angioedema attacks.

Australia’s Therapeutic Goods Administration (TGA) has approved CSL Ltd.’s Andembry (garadacimab) for preventing recurrent hereditary angioedema attacks, marking the first global approval for the drug that was discovered and developed in Australia by CSL scientists.
