Key Financial Metrics

Material Changes vs. Prior Period

• Increased Operating Expenses: Total operating expenses rose by $5.8 million (20%) to $34.9 million. Research and Development (R&D) expenses increased by $4.6 million to $28.0 million, driven by ongoing clinical trial costs for the Phase 3 CoMpass trial and manufacturing development. General and Administrative (G&A) expenses increased by $1.2 million to $6.9 million due to personnel growth and professional fees.
• Net Loss Expansion: Net loss increased by $6.2 million to $33.7 million, primarily due to higher operating expenses partially offset by a decrease in interest income ($1.2 million vs. $1.6 million in Q1 2025).
• Liquidity Position: Cash and marketable securities decreased by approximately $28.7 million from the prior year period, reflecting the burn rate of clinical operations. However, the company maintains a positive cash balance.
• Stock-Based Compensation: Stock-based compensation expense increased slightly to $3.8 million from $3.5 million.

Guidance, Outlook, and Subsequent Events

Subsequent Financing (May 2026): Following the quarter-end, on May 5, 2026, the company completed a Follow-On Offering raising approximately $280.8 million in net proceeds. This included the sale of 46.1 million shares of common stock and pre-funded warrants. Concurrently, the company used approximately $39.0 million of these proceeds to repurchase 6.9 million shares from Matrix Capital Management Master Fund, LP.

Liquidity Outlook: Management stated that prior to the May 2026 financing, there was substantial doubt about the company's ability to continue as a going concern. Following the financing, management concluded that the cash and marketable securities (including the new proceeds) are sufficient to fund operations into the second half of 2028.

Operational Outlook: The company continues to advance the Phase 3 CoMpass trial for bel-sar in early choroidal melanoma. It is also expanding development into metastases to the choroid and bladder cancer. The company expects expenses to increase substantially as it advances clinical trials and prepares for potential commercialization.

Risks: Key risks include the failure of bel-sar to achieve regulatory approval, delays in clinical trials, reliance on third-party manufacturers (CDMOs), and the need for additional capital if the current runway is exhausted sooner than expected.

Investor Verification Checklist

• Capital Runway: Verify the exact cash burn rate post-May 2026 financing to confirm the "second half of 2028" liquidity estimate.
• Phase 3 Trial Status: Monitor enrollment rates and interim data for the CoMpass trial, as the company's valuation is heavily dependent on this single asset.
• Manufacturing Dependencies: Assess the stability of relationships with Contract Development and Manufacturing Organizations (CDMOs), as the company has no internal manufacturing capabilities.
• Regulatory Pathway: Review the status of the Special Protocol Assessment (SPA) with the FDA and any potential changes to the approval criteria for bel-sar.
• Dilution Impact: Analyze the impact of the May 2026 Follow-On Offering and the Matrix Repurchase on existing shareholder ownership percentages.
