(Nasdaq: ZNTL), a clinical-stage biopharmaceutical company discovering and developing clinically differentiated small molecule therapeutics targeting fundamental biological pathways of cancers, today announced a restructuring of its business operations and research and development organization to support execution of late-stage development for its WEE1 inhibitor product candidate, azenosertib, and extend its cash runway beyond a data readout from its potentially registration-enabling DENALI Part 2 study, anticipated by the end of 2026. "Zentalis is sharply focused on our goal of bringing azenosertib to patients with gynecological malignancies,” said Julie Eastland, Chief Executive Officer. “To support this goal, we have made the necessary decisions to efficiently organize our company and allocate our capital resources to extend cash runway beyond an anticipated azenosertib data readout that we believe has the potential to be registration-enabling. I want to thank all the individuals departing the Company for their valuable contributions to all Zentalis programs and the development of azenosertib. Tomorrow morning, we look forward to hosting a corporate event to share updated azenosertib clinical data and provide a development and regulatory update, including plans for our registration-intent studies, as we work to bring this therapeutic candidate forward to patients as quickly as possible.” The workforce reduction is expected to be substantially completed in the second quarter of 2025. Corporate Event DetailsOn January 29, 2025, at 8:00am ET Zentalis will host a virtual corporate event to present data from its studies of azenosertib and provide a development and regulatory update.

About AzenosertibAzenosertib is a novel, selective, and orally bioavailable inhibitor of WEE1 currently being evaluated as a monotherapy and in combination clinical studies in ovarian cancer and additional tumor types. WEE1 acts as a master regulator of the G1-S and G2-M cell cycle checkpoints, through negative regulation of both CDK1 and CDK2, to prevent replication of cells with damaged DNA. By inhibiting WEE1, azenosertib enables cell cycle progression, despite high levels of DNA damage, thereby resulting in the accumulation of DNA damage and leading to mitotic catastrophe and cancer cell death. About Zentalis Pharmaceuticals Zentalis® Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company discovering and developing clinically differentiated small molecule therapeutics targeting fundamental biological pathways of cancers. The Company’s lead product candidate, azenosertib (ZN-c3), is a potentially first-in-class and best-in-class WEE1 inhibitor for advanced solid tumors. Azenosertib is being evaluated as a monotherapy and in combination across multiple clinical trials and has broad franchise potential. In clinical trials, azenosertib has been well tolerated and has demonstrated anti-tumor activity as a single agent across multiple tumor types and in combination with several chemotherapy backbones. As part of its azenosertib clinical development program, the Company is exploring enrichment strategies targeting tumors of high genomic instability, such as Cyclin E1 positive tumors, homologous recombination deficient tumors and tumors with oncogenic driver mutations. The Company is also leveraging its extensive experience and capabilities across cancer biology and medicinal chemistry to advance its research on protein degraders.
