Kalvista Pharmaceuticals Inc.’s positive phase III news Feb. 13 with sebetralstat, an oral on-demand kallikrein inhibitor, in hereditary angioedema (HAE), sparked Wall Street speculation about competitor Pharvaris BV with deucrictibant, a bradykinin B2 receptor antagonist.
Promising early data continue to roll out for Intellia Therapeutics Inc.’s hereditary angioedema (HAE) candidate, NTLA-2002, with one of the earliest treated patients in the phase I study remaining attack-free for more than a year. But it was the systemic CRISPR candidate’s potential as a one-time treatment that generated the most discussion on the company’s call as investors tried to assess its potential advantage in a crowded HAE market.
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.
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.
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.
HONG KONG – Takeda Pharmaceutical Co. Ltd. has received Chinese approval for Takhzyro (lanadelumab), its fully human monoclonal antibody, delivered via subcutaneous injection, for prophylaxis to prevent attacks of hereditary angioedema (HAE) in patients 12 and older.
Kalvista Pharmaceuticals Inc. made big news in October 2017 by way of its handsome deal with Merck & Co. Inc. to advance KVD-001, an intravitreal injection candidate to treat diabetic macular edema (DME).
