AstraZeneca Reports Favorable Calquence Data
AstraZeneca says data from its Phase 3 AMPLIFY trial showed that Calquence (acalabrutinib) in combination with venetoclax, with or without obinutuzumab, demonstrated a statistically significant and clinically meaningful improvement in progression-free survival compared to standard-of-care chemoimmunotherapy in previously untreated adult patients with chronic lymphocytic leukemia.
Regarding the trial’s secondary endpoint of overall survival (OS), the company says “a trend” was observed in favor of Calquence in the combination administration. “The OS data were not mature at the time of this analysis and the trial will continue to assess OS as a key secondary endpoint,” it says.
“The progression-free survival and overall survival results from the AMPLIFY Phase III trial demonstrate the potential of including a BTK inhibitor in a fixed-duration regimen,” AstraZeneca says. If approved, Calquence would be the only second-generation BTK inhibitor for both a treat-to-progression and fixed-duration treatment, it adds.
