We received Orphan Drug Exclusivity for PEDMARK® in January 2023, which provides seven years of market exclusivity from its FDA approval on September 20, 2022, until September 20, 2029. We currently have six patents listed for PEDMARK® in the FDA Orange Book. In September 2022, the USPTO issued Patent No. 11,291,728 (the “US ‘728 Patent”), in December 2022, the USPTO issued Patent No. 11,510,984 (“US ‘984 Patent”) and in April 2023, the USPTO issued Patent No. 11,671,793 (“US ‘793 Patent”) that covers PEDMARK® pharmaceutical formulation. Further, additional issued patents included US 11,964,018 Patent (the “’US ‘018 Patent) and US 11,992,530 Patent (the “US ’530 Patent”) and US 11,998,604 Patent (the “US ’604 Patent”) covering methods of using our PEDMARK® product to reduce ototoxicity in a patient receiving a platinum based chemotherapeutic for the treatment of a cancer. The US ‘728, US ‘984 US ‘793, US ‘018, US’530 and US ’604 patents will expire in 2039. We are also pursuing additional patent applications in both the U.S. and internationally for PEDMARK®.

Additionally, on May 27, 2025, we were granted US 12,311,026 (the “US ‘026 Patent”) covering a method of using pharmaceutical compositions comprising sodium thiosulfate and specific stabilizers to reduce ototoxicity in a patient receiving a platinum based chemotherapeutic for the treatment of a cancer. The US ‘026 Patent has an expiration date of July 2039.

In the U.S. and Europe, it is estimated that more than 10,000 pediatric may receive platinum-based chemotherapy on an annual basis. The incidence of ototoxicity depends upon the dose and duration of chemotherapy, and many of these children require lifelong hearing aids. PEDMARK® is the first and only therapy approved to mitigate the risk of ototoxicity associated with cisplatin, a form of platinum based chemotherapy, in pediatric patients aged one month and older with localized, non-metastatic solid tumors. Beyond the use of PEDMARK, only expensive, technically difficult, and sub-optimal cochlear (inner ear) implants have been shown to provide some benefit. Infants and young children that suffer ototoxicity at critical stages of development lack speech language development and literacy, and older children and adolescents lack social-emotional development and educational achievement.

The net cash used in operating activities for the three-month period ended March 31, 2025 was approximately $4,318 as compared to $39,047 net cash provided by operating activities during the same period in 2024. There was a increase in net loss of $14,713 in the three-month period ended March 31, 2025, as compared to the same period in 2024. The comparable decrease in net cash flow is primarily a result of the proceeds received from the Norgine transaction.

Under Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company determines it expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the Company satisfies its performance obligation(s). As part of the accounting for these arrangements, the Company must make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation.

Contingent milestones at contract inception are estimated at the amount which is not probable of a material reversal and included in the transaction price using the most likely amount method. Milestone payments that are not within the Company's control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received and therefore the variable consideration is constrained. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the

The calculation of the fair values of our stock-based compensation plans requires estimates that require management’s judgments. Under ASC 718, the fair value of each stock option is estimated on the grant date using the Black-Scholes option-pricing model. The valuation models require assumptions and estimates to determine expected volatility, expected life, expected dividends and expected risk-free interest rates. The expected volatility was determined using historical volatility of our stock based on the contractual life of the award. The risk-free interest rate assumption was based on the yield on zero-coupon U.S. Treasury strips at the award grant date. We also used historical data to estimate forfeiture experience. In valuing options granted in the three-month period ended March 31, 2025, we used the following weighted average assumptions:
