ZNTL Zentalis Pharmaceuticals Inc

Zentalis® Pharmaceuticals, Inc. (Nasdaq: ZNTL), a clinical-stage biopharmaceutical company discovering and developing clinically differentiated small molecule therapeutics targeting fundamental biological pathways of cancers, today announced changes to its executive leadership team to support the Company as it plans and executes registrational studies for its lead product candidate, azenosertib.

Julie Eastland has been appointed Chief Executive Officer, President and Director, succeeding Kimberly Blackwell, M.D., who will remain as a strategic advisor to the Board of Directors. Ms. Eastland is an accomplished biopharmaceutical executive with substantial leadership experience operating late-stage oncology companies. She previously served as Chief Executive Officer at Harpoon Therapeutics until the company’s acquisition by Merck in early 2024. In addition to Ms. Eastland’s appointment, Ingmar Bruns, M.D., has been appointed Chief Medical Officer. The Company also announced that Scott Myers has been appointed as Chairperson of the Zentalis Board of Directors.

"I am honored to join Zentalis during this exciting period as we execute azenosertib clinical development activities that, we believe, could support an accelerated approval,” said Julie Eastland, incoming Chief Executive Officer of Zentalis. “The azenosertib clinical results generated to date are compelling, and we believe this investigational medicine has the potential to become an important new treatment option for a significant segment of patients living with gynecological cancers. I look forward to working alongside the entire Zentalis team and Board, highly accomplished industry experts with a track record of successfully moving medicines through late-stage development and into commercialization.”

Ms. Eastland continued: “We plan to proceed with a sharp focus on the advancement of azenosertib, taking necessary actions to ensure the Company has the resources to successfully proceed forward. Our priorities are clear – we will work to rapidly initiate and complete the studies needed to obtain regulatory authority approval to get azenosertib to patients, and we will operate in a capital efficient manner in order to maximize shareholder value. In January 2025, we plan to host an investor event, where we will share updated azenosertib clinical data and a regulatory update, including plans for registration-intent studies.”

Kimberly Blackwell, M.D., added: “I am proud of our accomplishments advancing the development of azenosertib. We have administered azenosertib to approximately 800 patients with a variety of serious cancers in the clinic, as both a monotherapy and in combination with other modalities, and we’ve generated a substantial body of efficacy and safety data that inform further development. I believe that these data, in conjunction with the results of the pending studies, will ultimately support the approval of azenosertib as an entirely novel treatment option for gynecological cancers. I look forward to continuing to contribute and advise on the development of azenosertib.”

“On behalf of the Board, we would like to thank Dr. Blackwell for her meaningful contributions to Zentalis and her efforts advancing the azenosertib clinical program,” said Scott Myers, incoming Chairperson of the Zentalis Board of Directors. “We would also like to express our deep appreciation to Dave Johnson for his many contributions as a highly productive chairperson and in supporting the organization during this period of growth. I look forward to working with him on the Board going forward.”
