Key Clinical Findings (as of 2023)

• ELEVATE-TN Trial: Demonstrated superior progression-free survival (PFS) for ZYDELIG monotherapy and combination with obinutuzumab versus chlorambucil + obinutuzumab in treatment-naive CLL patients. PFS benefits were statistically significant, with median PFS not reached at data cutoff (median follow-up: 36 months).

• ASCEND Trial: Showed that ZYDELIG outperformed investigator’s choice (ibrutinib or temsirolimus) in relapsed/refractory MCL, with a hazard ratio (HR) for progression or death at 0.49 (95% CI: 0.30–0.80, p=0.003), and higher overall response rate (ORR).

• Ongoing Trials: Including the innovative combination with venetoclax (TRANSFORM) and investigations into first-line therapy in CLL, seeking to expand ZYDELIG’s therapeutic landscape.

Regulatory Approvals & Submissions

• FDA (United States): Approved in 2019 for relapsed/refractory MCL and in 2020 for first-line CLL in combination with obinutuzumab.
• EMA (Europe): Approved in 2019 for MCL, followed by approvals for CLL and SLL.
• Other regions: Approved or under review in Canada, Australia, and several Asian countries, with local trials supporting registration.
