Material Changes and Clinical Results
The primary material change reported is the successful completion of the BOLERO-2 trial, which demonstrated significant efficacy for everolimus combined with exemestane in postmenopausal women with ER+HER2- advanced breast cancer:
- Progression-Free Survival (PFS): Treatment with everolimus more than doubled PFS to 6.9 months compared to 2.8 months for exemestane alone (local investigator assessment).
- Risk Reduction: The combination therapy reduced the risk of cancer progression by 57% (hazard ratio 0.43).
- Independent Review: An independent central radiology review showed PFS extended to 10.6 months versus 4.1 months (hazard ratio 0.36).
- Regulatory Action: Novartis plans worldwide regulatory filings by the end of 2011 based on these data, marking the first submission for everolimus in breast cancer.
Outlook, Risks, and Management Commentary
Management views these results as a significant advance for women with postmenopausal ER+ breast cancer, addressing a critical unmet need where patients have developed resistance to previous hormonal therapies. The filing includes standard forward-looking statements regarding potential new indications and future revenues.
Risks and Contingencies:
- Regulatory Uncertainty: There is no guarantee that everolimus will be approved for this additional indication in any market.
- Clinical Risks: Unexpected clinical trial results or additional analysis of existing data could alter expectations.
