Strengthened management team with appointments of Diana Hausman, M.D., as Chief Medical Officer and Kyle Rasbach, Ph.D., Pharm.D., as Chief Business Officer
$483 million cash balance as of December 31, 2023, with projected cash runway into 2026
NEW YORK and SAN DIEGO, Feb. 27, 2024 (GLOBE NEWSWIRE) -- 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 financial results for the year ended December 31, 2023, and highlighted recent corporate accomplishments.
"Zentalis is making remarkable progress in advancing our clinical development program for azenosertib, our potentially groundbreaking WEE1 inhibitor, across various tumor types," stated Kimberly Blackwell, M.D., Chief Executive Officer of Zentalis. "In November 2023, we disclosed promising clinical data demonstrating the potential of azenosertib as an effective monotherapy in ovarian cancer and uterine serous carcinoma. Our team is diligently executing a clinical strategy, which is firmly on track, designed to rapidly bring this promising therapeutic option to patients with gynecological cancers that continue to have a poor prognosis based on currently available treatment options. We anticipate an exciting and data-rich period ahead during the remainder of 2024 and into 2025 where we plan to share multiple clinical datasets to help further demonstrate the potential of azenosertib in multiple cancer types as a monotherapy and in combination."
Program Updates and Highlights
Azenosertib development program updates. In November 2023, the Company announced an updated analysis of the ongoing Phase 1 clinical trial of azenosertib as a monotherapy in solid tumors (ZN-c3-001), which continued to show anti-tumor activity with intermittent dosing. In the same population of 19 platinum resistant or refractory ovarian cancer and uterine serous carcinoma (USC) patients that were included in the data reported on June 6, 2023, the objective response rate (ORR) was 37%. Median follow-up had increased and the median progression free survival (mPFS) had increased to 6.5 months. The Company also disclosed in November 2023, that, with additional safety-evaluable patients and follow-up, azenosertib continued to demonstrate a favorable safety and tolerability profile similar to or better than approved ovarian cancer products.

Azenosertib development continues to progress across a broad array of tumor types. Azenosertib is being evaluated in more than 10 ongoing and planned clinical trials as a monotherapy and in combinations supported by compelling scientific rationales across a broad array of tumor types, including platinum resistant ovarian cancer (PROC), platinum sensitive ovarian cancer (PROC), BRAF mutant metastatic colorectal cancer, and other solid tumors. In addition, the Company is evaluating azenosertib and its BCL-2 inhibitor in patients with relapsed or refractory Acute Myeloid Leukemia (AML).
On track to disclose multiple clinical data readouts during 2024 and 2025 (anticipated milestones noted below) and on track to submit its first New Drug Application (NDA) for azenosertib in a gynecologic malignancy in 2026.
Corporate Updates
Strengthened Leadership Team with the addition of Diana Hausman, M.D. as Chief Medical Officer, and Kyle Rasbach, Ph.D., Pharm.D. as Chief Business Officer. Dr. Hausman is an oncologist with extensive experience in all aspects of drug development and clinical strategy, including over a decade of experience as a Chief Medical Officer at various biopharma companies. During her career, she has contributed to the development of multiple cancer therapeutics, including small molecules, antibody drug conjugates, and immunotherapies. Dr. Rasbach joins from Eventide Asset Management, where he was a Portfolio Manager for Eventide’s healthcare and life sciences strategies, a Managing Director for Eventide Ventures, and a Senior Research Analyst for other Eventide investments.

Full Year 2023 Financial Results
Cash, Cash Equivalents and Marketable Securities Position: As of December 31, 2023, Zentalis had cash, cash equivalents and marketable securities of $482.9 million. The Company believes that its existing cash, cash equivalents and marketable securities as of December 31, 2023 will be sufficient to fund its operating expenses and capital expenditure requirements into 2026. The December 31, 2023 cash, cash equivalents and marketable securities balance does not reflect the up-front payment from Immunome of $35 million in cash and Immunome stock, which was received in January 2024, as the Company’s agreement was executed and announced in January 2024.
Research and Development Expenses: Research and development (R&D) expenses for the year ended December 31, 2023 were $189.6 million, compared to $172.7 million for the year ended December 31, 2022. The increase of $16.9 million was primarily due to a $7.5 million increase in expense relating to our cost sharing relationship with Zentera that was terminated in June 2023, a $7.4 million increase related to personnel expenses, of which $5.8 million related to non-cash stock-based compensation expense, a $2.8 million increase in facilities and overhead expenses and a $2.8 million increase in consulting expense. These increases were partially offset by decreases of $2.8 million and $0.9 million in collaborations expense and supplies/other expenses, respectively.
General and Administrative Expenses: General and administrative expenses for the year ended December 31, 2023 were $64.4 million, compared to $54.6 million during the year ended December 31, 2022. The increase of $9.8 million was primarily attributable to a $4.9 million non-cash operating lease impairment charge, a $5.1 million increase related to personnel expenses, of which $3.7 million related to non-cash stock-based compensation expense, and $1.4 million related to outside services. This was partially offset by a $1.6 million decrease in facilities and overhead and other expense.
About Azenosertib
Azenosertib is a potentially first-in-class and best-in-class small molecule WEE1 inhibitor in development for the treatment of cancer. Inhibition of WEE1, a DNA damage response kinase, drives cancer cells into mitosis without being able to repair damaged DNA, resulting in cell death. Currently, there are no FDA-approved WEE1 inhibitors, and azenosertib has been designed for superior selectivity and pharmacokinetic properties. Azenosertib is being developed in therapeutic areas of high unmet need and is being evaluated as a monotherapy, in combination with chemotherapy, and in combination with molecularly targeted agents.
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 and hematologic malignancies. 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. Zentalis has operations in both New York and San Diego.
