Material Changes and Clinical Milestones

- Trial Design: ASPENOVA is a randomized, confirmatory trial expected to enroll approximately 420 patients.
- Comparison Arm: The study compares azenosertib monotherapy (400mg QD 5:2 schedule) against the investigator's choice of standard-of-care single-agent chemotherapy (paclitaxel, pegylated liposomal doxorubicin, gemcitabin, or topotecan).

- Financial Viability: The Company has incurred and expects to continue to incur significant losses and has a need for additional funding, which may not be available.
- Development Risks: Early clinical trial outcomes may not predict later success; unforeseen events could cause delays; and product candidates may cause serious adverse side effects.
