Once-monthly subcutaneous injections of CSL Ltd.’s CSL-312 (garadacimab) significantly reduced the rate of hereditary angioedema (HAE) attacks compared to placebo, meeting both primary and secondary endpoints in the pivotal phase III Vanguard trial. Based on the trial results, CSL will file global regulatory submissions later in 2023. Based on the trial results, CSL will file global regulatory submissions later in 2023. A humanized anti-factor XIIa monoclonal antibody, garadacimab is self-administered by subcutaneous administration once monthly, which is a huge convenience for patients, Andrew Nash, CSL’s chief scientific officer and senior vice president for research, told BioWorld.

Biocryst Pharmaceuticals Inc.’s unveiling of real-world data Feb. 24 with its approved Orladeyo (berotralstat) for prophylactic treatment of hereditary angioedema (HAE) brought more attention to the space, due to yield findings from would-be competitors in the near term.
Researchers from BioCryst Pharmaceuticals Inc. have developed a series of plasma kallikrein inhibitors with potential for the treatment of hereditary angioedema (HAE).
Shire Human Genetic Therapies Inc. has discovered new plasma kallikrein (KLKB1) inhibitors reported to be useful for the treatment of hereditary angioedema and diabetic macular edema.
Biocryst Pharmaceuticals Inc. caught some industry observers by surprise early in 2022 when it upped its peak sales estimate for Orladeyo (berotralstat), its oral therapy for prevention of hereditary angioedema attacks, from $500 million to $1 billion. But blockbuster status appears more attainable following the latest setback from a potential competitor, as safety concerns prompted Kalvista Pharmaceuticals Inc. management to ax its phase II study testing KVD-824 in prevention of HAE attacks.
Bearish investors dwelling on a single grade 4 liver enzyme elevation seemed to be the cause for Intellia Therapeutics Inc.’s sinking stock Sept. 16, despite the company reporting impressive, though early stage, data for its leading systemically administered CRISPR candidates targeting hereditary angioedema (HAE) and amyloid transthyretin (ATTR) amyloidosis.
Shares of Pharvaris NV (NASDAQ:PHVS) fell 34% Aug. 22 to close at $12.15 after the company reported the U.S. FDA placed a clinical hold on PHA-121, its oral bradykinin B2-receptor antagonist for hereditary angioedema (HAE), citing a review of nonclinical data. PHA-121, which goes after the same target as well-established injectable HAE drug Firazyr (icatibant, Takeda Pharmaceutical Co. Ltd.), is the active ingredient in Pharvaris’ two lead programs: PHVS-416, a softgel capsule formulation, and PHVS-719, an extended-release tablet formulation.
Recently published real-world data with Firazyr (icatibant), the selective B2 bradykinin receptor antagonist from Takeda Pharmaceutical Co. Ltd. to treat acute hereditary angioedema (HAE) attacks, trained a spotlight on the space, where a handful of players compete. Among the prospects is the early stage but intriguing Star-0215 from Astria Therapeutics Inc., which could be the next advance in the kallikrein-inhibitor class.
Kalvista Pharmaceuticals Inc.’s chief development officer, Christopher Yea, said the across-the-board positive phase II top-line data with KVD-900 for on-demand use against hereditary angioedema (HAE) attacks will open “a very flexible discussion with regulators” regarding the design and endpoints of the phase III study to come with the oral kallikrein inhibitor. Shares of the Cambridge, Mass.-based firm (NASDAQ:KALV) closed at $33.50, up $17.89, or 115%, after reaching a high of $45, as Wall Street digested the findings.
