Debt and Liquidity: The company has no significant long-term debt. Total liabilities are primarily composed of deferred revenue from Schering AG ($13.8 million) and accrued expenses ($7.3 million). Liquidity is strong, with cash balances increasing by approximately $17.7 million during the period, driven by equity financing and collaboration payments.
Material Changes vs. Prior Period
- Revenue Generation: Revenue increased from $0 in the prior year to $11.6 million for the six months ended June 30, 2006. This is entirely attributable to the Schering AG collaboration, including amortization of a $20 million upfront fee and reimbursement for 50% of eligible R&D costs.
- Operating Expenses: Total operating expenses rose significantly to $23.0 million (from $9.0 million in 2005). Research and Development (R&D) expenses increased to $19.4 million (from $6.0 million), primarily due to the initiation and scaling of the Phase 3 pivotal trial for TOCOSOL Paclitaxel.
- Stock-Based Compensation: The adoption of SFAS 123R on January 1, 2006, resulted in a significant increase in non-cash stock-based compensation expense ($1.0 million for the six months ended June 30, 2006, compared to $3,462 in the prior year).
- Cash Position: Cash and cash equivalents grew from $49.3 million at year-end 2005 to $67.0 million at June 30, 2006. This increase was fueled by a registered direct offering in May 2006 raising net proceeds of $28.6 million.
Guidance, Outlook, and Risks
Outlook and Capital Resources: Management believes existing cash and cash equivalents, combined with future payments and cost-sharing under the Schering agreement, will fund operations into 2008. However, the company anticipates needing additional capital in 2008 to support continued development, commercialization, and obligations under the collaboration agreement. The total estimated cost of the pivotal Phase 3 trial is between $45 million and $50 million.
Management Commentary:
- Phase 3 Trial: Enrollment for the pivotal Phase 3 trial in metastatic breast cancer is ongoing, with completion expected by September or October 2006. The New Drug Application (NDA) is anticipated to be submitted by the end of 2007.
- Regulatory Strategy: The company is pursuing a 505(b)(2) NDA submission, relying on prior FDA findings for Taxol. Approval requires demonstrating either superior efficacy or non-inferior efficacy combined with a change in the Taxol label to include weekly dosing.
- Manufacturing: Schering AG assumed responsibility for manufacturing TOCOSOL Paclitaxel in March 2006, though a facility has not yet been identified.
Risks and Contingencies:
- Regulatory Uncertainty: There is no assurance that the Phase 3 trial will demonstrate non-inferior or superior efficacy compared to Taxol. If the Taxol label is not changed to include weekly dosing, the company may need to rely on third-party data (CALGB 9840) or conduct additional trials.
- Dependency on Partner: The company is heavily dependent on Schering AG for funding, clinical development outside the U.S., and future commercialization. A pending tender offer by Bayer AG to acquire Schering introduces uncertainty regarding the future of the partnership.
- Operating Losses: The company has a history of operating losses and an accumulated deficit of $98.4 million. Profitability is contingent upon regulatory approval and commercial success.
Key Facts for Investor Verification
- Revenue Source: Verify the sustainability of revenue, which is currently 100% dependent on the Schering AG collaboration agreement (amortization of upfront fees and R&D reimbursements).
- Phase 3 Trial Status: Confirm the enrollment rates and interim data for the pivotal Phase 3 trial, as the company's valuation hinges on the successful completion and positive results of this study.
- Capital Runway: Assess the sufficiency of the $67 million cash balance against the estimated $45-$50 million cost of the Phase 3 trial and the company's obligation to fund 50% of certain U.S. studies conducted by Schering.
- Partnership Stability: Monitor the outcome of the Bayer AG tender offer for Schering AG and any potential impact on the collaboration agreement or funding commitments.
- Regulatory Pathway: Verify the FDA's stance on the 505(b)(2) pathway and the likelihood of the Taxol label being updated to include weekly dosing, which is a critical contingency for the NDA submission.
