Trial or other data

Nov 20Orally administered BCX7353 will compete with Takhzyro (lanadelumab-flyo) which is a kallikrein inhibitor that is given by s.c. injection. In PIII data that led to its approval, pts treated with Takhzyro experienced a “statistically significant reduction in mean HAE attack frequency of 87% vs. placebo [5].
Oct 20In the APeX-2 trial (n=121), berotralstat was associated with a reduction in the rate of investigator-confirmed hereditary angioedema attacks versus placebo (2.35 attacks/month) at both 110mg (1.65 attacks/month; p=0.024) and 150mg (1.31 attacks/month; p<0.001) doses [8].
May 19Data from the double-blind, placebo-controlled PIII APeX-2 trial (n=121) for prevention of HAE attacks showed that BCX7353 (both 110mg and 150mg) achieved its primary endpoint (rate of HAE attacks over 24 weeks) vs. placebo. The 150mg dose reduced the HAE attack rate by 44% vs. placebo (p5% of pts in APeX-2 were nausea, dyspepsia and diarrhea.[5]
Sep 18Results from the ZENITH-1 trial (NCT03240133) showed that a single 750 mg oral dose of BCX7353 was well tolerated and superior to placebo (p<0.05) against the majority of efficacy endpoints evaluated in HAE patients suffering an acute attack. compared to placebo, improvement in symptoms and VAS scores was seen as early as one hour after oral BCX7353 dosing, and was sustained through 24 hours.[4].
Feb 18PIII APeX-2 trial to evaluate the efficacy of two capsule doses of BCX 7353 (110mg and 150mg) administered orally to reduce the frequency of attacks in patients with type I and type II HAE starts (NCT03485911). The primary endpoint of the trial is to determine the rate of angioedema attacks over 24 weeks of study drug administration. 96 participants will be recruited in the US, Canada, United Kingdom, Macedonia and Romania. Collection of primary outcome data due to complete May 19 [2].
