Revenue Composition: 100% of revenue is derived from the Collaboration and License Agreement with Bayer Schering Pharma AG, consisting of amortization of an upfront license fee ($5.5 million) and reimbursements for research and development services ($16.9 million).
Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 171% from $8.3 million in 2005 to $22.4 million in 2006, driven by the recognition of the upfront license fee amortization and increased R&D reimbursements from Bayer Schering.
- Expense Increase: Operating expenses rose 62% to $48.7 million. Research and Development (R&D) expenses increased 68% to $41.1 million, primarily due to the initiation and scaling of the pivotal Phase 3 clinical trial for TOCOSOL Paclitaxel and the implementation of SFAS 123R (stock-based compensation).
- Liquidity Position: Cash and marketable securities increased by $9.0 million to $58.3 million, supported by a $28.6 million equity financing in May 2006 and collaboration payments, offset by operating losses.
- Stock-Based Compensation: The company adopted SFAS 123R in 2006, recording $2.2 million in stock-based compensation expense, which was not recorded in 2005 under the previous accounting standard.
Guidance, Outlook, and Risks
Outlook and Guidance:
- Revenue Decline Expected: Management expects revenue to decline substantially in 2007 as reimbursements from Bayer Schering associated with the Phase 3 trial wind down and Bayer assumes full manufacturing responsibility.
- Capital Requirements: The company estimates existing cash and collaboration funds will be sufficient to operate through the second quarter of 2008. Additional capital will be required in 2008 to complete development and commercialization.
- Phase 3 Trial: Enrollment for the pivotal Phase 3 trial in metastatic breast cancer closed in November 2006 with 821 patients. The total estimated cost is approximately $50 million (Sonus share). The New Drug Application (NDA) is expected to be submitted by Bayer Schering in the second quarter of 2008.
Key Risks and Contingencies:
- Regulatory Approval: Success depends entirely on the Phase 3 trial results. The FDA requires demonstration of superior efficacy or non-inferior efficacy combined with a change in the Taxol label to weekly dosing. If the FDA does not accept the CALGB 9840 data to support the weekly dosing reference arm, substantial additional costs and time will be required.
- Operating Losses: The company has an accumulated deficit of $111.7 million and expects to incur net losses for the foreseeable future.
- Dependence on Partner: Sonus relies on Bayer Schering for funding (50% cost share), manufacturing, and global commercialization outside the U.S. The acquisition of Schering by Bayer AG was completed in 2006, though no material effect has been observed yet.
- Competition: Intense competition exists from Abraxis BioScience (ABRAXANE®), Sanofi-aventis (Taxotere®), and generic paclitaxel products.
Investor Verification Checklist
- Phase 3 Trial Status: Verify the timeline for the release of Phase 3 clinical data and the FDA's acceptance of the study design and statistical analysis plan.
- Cash Runway: Confirm the sufficiency of the $58.3 million cash balance to fund operations through Q2 2008, considering the high burn rate of the Phase 3 trial.
- Revenue Sustainability: Assess the impact of the expected revenue decline in 2007 and the company's ability to secure additional financing before the Q2 2008 horizon.
- Regulatory Strategy: Monitor the FDA's stance on the 505(b)(2) pathway and the acceptance of the CALGB 9840 data as a reference arm for weekly Taxol dosing.
- Stock-Based Compensation: Review the impact of SFAS 123R on future operating expenses and the dilution potential of outstanding options and warrants (approx. 9.2 million shares).
