AstraZeneca’s New Calquence Combinations Show Promise in CLL Treatment: Potential to Shift Clinical Practice

Positive Trial Results:
AstraZeneca's Calquence (acalabrutinib) in combination with venetoclax, with or without obinutuzumab, demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared to standard-of-care chemoimmunotherapy in previously untreated CLL patients.

Overall Survival Trend:
A favourable trend in overall survival (OS) was observed, though OS data were not mature at the time of analysis.
Fixed-Duration Treatment: The combination showed potential as a fixed-duration treatment, allowing patients to take breaks from therapy and potentially reducing long-term adverse effects and drug resistance.

Clinical Impact:
The AMPLIFY Phase III trial results suggest that Calquence combinations could become new treatment standards for CLL, offering more options for patients and healthcare providers.

Safety Profile:
The safety and tolerability of the combination were consistent with the known profiles of each medicine, with no new safety signals identified and low rates of cardiac toxicity observed.

Global Significance:
CLL is the most prevalent type of leukemia in adults worldwide, with approximately 40,000 patients treated annually in the first-line setting.

Regulatory and Medical Presentation:
The data will be presented at a forthcoming medical meeting and shared with global regulatory authorities.
