Key Financial Metrics

Material Changes vs. Prior Period

• Net Loss Expansion: Net loss increased by $6.7 million (45%) for the three months ended June 30, 2026, compared to the same period in 2025. For the six-month period, the loss increased by $12.6 million (47%).
• R&D Expenses: R&D expenses rose significantly, increasing by $6.2 million (57%) for the quarter and $10.6 million (53%) for the six months. This was driven by higher direct costs for ongoing clinical trials (NMIBC, LMs, and IV Choline Chloride) and increased indirect personnel and CMC-related costs.
• G&A Expenses: G&A expenses increased by $0.6 million (9%) for the quarter and $1.6 million (15%) for the six months, primarily due to higher personnel-related costs.
• Cash Position: Total liquidity decreased from approximately $197.9 million at December 31, 2025, to $161.9 million at June 30, 2026. Net cash used in operating activities was $36.7 million for the six months ended June 30, 2026.
• Investing Activities: Unlike the prior year period which saw significant cash outflows for securities purchases, the current six-month period showed a net cash inflow of $3.0 million from investing activities due to proceeds from maturities exceeding new purchases.

Guidance, Outlook, and Risks

• Liquidity Outlook: Management believes current financial resources are sufficient to satisfy estimated liquidity needs for at least 12 months from the date of issuance. However, the company will need to raise additional capital to fully realize its strategic plans.
• Clinical Milestones:
  • NMIBC (ADVANCED-2): Enrollment for the BCG-Unresponsive registrational cohort is expected to complete in Q4 2026. The company announced a 68.0% six-month complete response rate in 25 BCG-Unresponsive patients.
  • LMs (STARBORN-1): Enrollment is expected to complete in Q4 2026. A Biologics License Application (BLA) is targeted for submission in the second half of 2027.
  • IV Choline Chloride (THRIVE-3): Interim results from the dose-confirmation portion are anticipated in Q4 2026.
• Capital Markets: The company has a $300 million shelf registration statement effective as of May 2026 and an At-The-Market (ATM) program for up to $100 million, though no shares were sold under the ATM program in the first half of 2026.
• Risks: Key risks include the need for additional financing, volatility in capital markets, the uncertainty of clinical trial outcomes, and the potential inability to obtain regulatory approval. The company has no current or near-term revenues.

Investor Verification Checklist

• Cash Burn Rate: Verify the sustainability of the $36.7 million operating cash burn over six months against the $161.9 million liquidity position.
• Clinical Data Durability: Review the durability of the reported 68% complete response rate in the NMIBC trial and the 100% clinical success rate in the LMs trial to assess regulatory approval probability.
• Financing Needs: Monitor upcoming capital raises given the 12-month liquidity runway and the lack of revenue.
• Warrant Expirations: Note that April 2024 Common Warrants expired on June 29, 2026, reducing potential dilution but also eliminating a source of capital.
• Expense Trends: Track the continued increase in R&D and G&A expenses to ensure they align with clinical milestones.
