a planned interim analysis of ORR will be conducted when the first 225 randomized patients reach one year of treatment in June 2024.

Cash and cash equivalents as of March 31, 2024 were $118.0 million, compared to $143.2 million at December 31, 2023. During the three months ended March 31, 2024, the company used cash, cash equivalents and restricted cash of $24.9 million. The increase in cash use was primarily driven by milestone payments and payment of other accrued expenses associated with clinical trials, as well as the payment of year-end bonuses. The company continues to expect that it will have sufficient cash to run the company into the fourth quarter of 2025.
