On November 3, 2025, the Company entered into a securities purchase agreement with the purchaser, pursuant to which the Company agreed to issue and sell to the purchaser in a private placement transaction (the “November 2025 Offering”) a pre-funded warrant to purchase up to 625,156 shares of common stock of the Company, par value $0.00001 per share for aggregate gross proceeds of approximately $2.5 million, before deducting placement agent fees to WestPark Capital, Inc. and offering expenses payable by the Company.

The Company intends to use the net proceeds from the November 2025 Offering for marketing, general corporate purposes and working capital purposes.
Current report
In the current reporting period, the Company calculated the fair value of the October 2024 Convertible Bridge Notes assuming a mandatory conversion due to the relatively short duration between the balance sheet date and the maturities in October 2025. The fair value was determined by calculating the number of shares into which the October 2024 Convertible Bridge Notes will convert in a mandatory conversion scenario, multiplied by the fair value per share of the Company’s common stock at the balance sheet date.

Previous wording
Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation, to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore the application of the PC-RAD Test, predictive biomarkers of radiation response. The clinical development of Ropidoxuridine has included completion of a Phase I clinical trial to establish drug bioavailability and a maximum tolerated dose for use in Phase II clinical trials. TCG GreenChem, with whom we have contracted for process research, development and cGMP compliant manufacture of IPdR, has manufactured the API of Ropidoxuridine and the University of Iowa Pharmaceuticals has formulated the drug product for use in our upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. The drug product (capsules) were shipped to CRO Theradex Oncology and distributed to clinical trial sites that are fully approved to enroll patients in the trial. Shuttle received approval from the FDA to begin the clinical trial. The FDA thereafter made recommendations to expand the clinical trial to include a randomized dose “optimization” step and we agreed with the recommendation. Meetings with engaged clinical sites to review the protocol documents have occurred and FDA required IRB approvals have been received. With FDA recommended changes incorporated into the revised protocol and the completion of site initiation visits, we commenced our Phase II clinical study in October 2024. The Company’s radiation biomarker project and the health disparities project have been completed and we are proceeding with plans for clinical validation and potential for commercialization of Ropidoxuridine as a radiation sensitizer.

As permitted under ASC 825, Financial Instruments (“ASC 825”), we elected the fair value option to account for the October 2024 Convertible Bridge Notes. The valuation of the October 2024 Convertible Bridge Notes utilizes a Monte Carlo simulation model. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned to not achieving a successful capital raise and a registration of related securities. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.

Previous wording
The significant inputs and assumptions used to estimate the fair value also include: (i) the expected timing of conversion, (ii) the amount subject to equity conversion, (iii) the sum of the notes’ principal and unpaid accrued interest, (iv) expected volatility, (v) risk-free interest rate, (vi) the discount rate, (vii) volume-weighted average price (“VWAP”), (viii) illiquidity discounts, and (ix) probabilities assigned. The October 2024 Convertible Bridge Notes are subject to revaluation at the end of each reporting period, with changes in fair value recognized in the accompanying unaudited condensed consolidated statements of operations, or for changes due to our credit worthiness, if any, as a component of other comprehensive income.

For warrants with uncertain or more complex terms (such as variability in the warrant shares or exercise price), we may utilize more complex models to address such provisions, including Monte Carlo simulation models. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.

For warrants with uncertain or more complex terms (such as variability in the warrant shares or exercise price), we may utilize more complex models to address such provisions, including Monte Carlo simulations or Probability-Weighted Expected Return Methods (“PWERM”). Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average. PWERM models require the estimate of an entity’s per share value of its common stock at various future outcomes and assigns a probability to each scenario. The value per share is then weighted based on the respective probabilities to determine a weighted-average expected return.
Previous wording
For our derivative financial instruments classified as a liability, we use a Monte Carlo valuation model to value the derivative instruments at inception and on subsequent valuation dates. The model requires the use of simulations that are weighted based the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average. The Monte Carlo simulation uses an implied VWAP for valuation. The implied VWAP was backsolved by setting the summation of the parts (e.g., derivatives and debt without derivatives) equal to the cash proceeds and is updated each period.

The use of Monte Carlo valuation models require key inputs, some of which are based on estimates and judgements by management. Any change to these key inputs could produce significantly higher or lower fair value measurements.

*Research and Development.*Total research and development (“R&D”) expense was $1.0 million for the three months ended June 30, 2025, as compared to $0.6 million to the three months ended June 30, 2024. The increase in total R&D expense of $0.4 million, or 59%, is primarily related to the Company having completed production of the drug product and the start of work related to the initiation of trials including contract research organization (“CRO”) expenses, clinical trial sites, other regulatory activities.
