Investigators at Poseida Therapeutics Inc. developed P-KLKB1-101, a nonviral KLKB1 gene editing therapy, being developed for the treatment of hereditary angioedema (HAE).
Kalvista Pharmaceuticals Ltd. has disclosed coagulation factor XII (FXIIa) inhibitors reported to be useful for the treatment of hereditary angioedema and thrombotic disorder.
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.
Kalvista Pharmaceuticals Inc. is promising to “change the paradigm” in the treatment of hereditary angioedema, after announcing positive phase III data for its oral on-demand kallikrein inhibitor sebetralstat. Rather than waiting four to five hours to self-administer therapy, as is the case for approved injectable on-demand therapies, there was a median time to dosing of 10 minutes after the start of an attack in the ongoing open label extension trial and a median time to dosing of 41 minutes in the 136-patient placebo-controlled phase 3 trial.
Dysregulation of the kallikrein-kinin system (KKS) is involved in hereditary angioedema (HA) pathophysiology; thus, the inhibition of factor XIIa (FXIIa), a central mediator of angioedema and initiator of KKS, is a therapeutic strategy to prevent and treat HA attacks.
Pharvaris NV’s phase II top-line data from the Chapter-1 trial testing oral bradykinin B2 receptor antagonist deucrictibant in hereditary angioedema (HAE) wowed Wall Street and sparked speculation regarding where the drug might fit in the increasingly competitive landscape.
Astria Therapeutics Inc.’s potential $320 million deal with Ichnos Sciences Inc. to bring aboard an OX40 portfolio for atopic dermatitis puts the firm in line to compete with big pharma, which is trying – at a much later stage – the same mechanism of action.
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.
