Material Changes and Events
- FDA Acceptance for BRUKINSA: On May 19, 2021, the U.S. FDA accepted a supplemental new drug application (sNDA) for BRUKINSA (zanubrutinib) for the treatment of adult patients with marginal zone lymphoma who have received at least one prior anti-CD20-based therapy. The FDA granted priority review for this application.
- Phase 3 Trial Success for Tislelizumab: On May 21, 2021, BeiGene announced that the Phase 3 RATIONALE 309 trial of tislelizumab (anti-PD-1 antibody) combined with chemotherapy met its primary endpoint of progression-free survival (PFS) at interim analysis. This was for first-line treatment of recurrent or metastatic nasopharyngeal cancer.
- Clinical Outcomes: The combination of tislelizumab and chemotherapy demonstrated a statistically significant improvement in PFS compared to chemotherapy alone in the intention-to-treat population. The safety profile was consistent with known risks with no new safety signals identified.
Guidance, Outlook, and Risks
Regulatory Timeline: The Prescription Drug User Fee Act (PDUFA) target action date for the BRUKINSA sNDA is set for September 19, 2021.
Management Commentary: The company highlighted the statistical significance of the PFS improvement in the RATIONALE 309 trial and the consistency of the safety profile for tislelizumab when combined with chemotherapy.
Risks and Contingencies: While the filing reports positive interim results and regulatory acceptance, it does not explicitly detail new risks. Standard contingencies for biopharmaceutical companies include the possibility that regulatory approvals may not be granted despite priority review, or that final trial results may differ from interim analyses.
