Initiated a potentially registrational Phase 1/2 study of ZN-d5 in patients with relapsed or refractory light chain (AL) amyloidosis

Cash runway extended into Q1 2024, with Pfizer’s equity investment and budget reallocation

NEW YORK and SAN DIEGO, May 05, 2022 (GLOBE NEWSWIRE) -- Zentalis Pharmaceuticals, Inc. (Nasdaq: ZNTL), a clinical-stage biopharmaceutical company focused on discovering and developing small molecule therapeutics targeting fundamental biological pathways of cancers, today announced financial results for the first quarter ended March 31, 2022 and highlighted recent corporate accomplishments.

“In the first quarter of 2022, we achieved multiple clinical milestones and expanded our strategic partnerships with industry leaders,” commented Dr. Anthony Sun, Chairman and Chief Executive Officer of Zentalis. “Most recently at AACR, we shared promising clinical data on ZN-c3 – our potentially best-in-class Wee1 inhibitor – from two ongoing trials, in addition to preclinical data on its potential in settings including AML, PARP-resistant ovarian cancer, and in combination with ZN-d5, our BCL-2 inhibitor. The urgency for novel, tolerable treatments that address cancer patients’ unmet needs remains high, and we have prioritized the development of ZN-c3 and ZN-d5, as we are confident in their ability to fill treatment gaps for a range of solid and liquid tumors. Furthermore, we are thrilled to partner with Pfizer and Caris Life Sciences and are grateful for their support as we work toward delivering differentiated oncology candidates to patients in need.”

Program Highlights:

• In April 2022, Zentalis presented five abstracts at the American Association of Cancer Research (AACR) Annual Meeting and held a webcast event with Key Opinion Leader, Kathleen Moore, M.D., to further discuss the clinical and preclinical data. Additional details on the data presented at the AACR conference are available here.
• In March 2022, Zentalis announced the first patient was dosed in the potentially registrational Phase 1/2 study of ZN-d5, the Company’s BCL-2 inhibitor, in patients with relapsed or refractory light chain (AL) amyloidosis. The trial is a global, single arm, open-label study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of ZN-d5.
• In March 2022, Zentalis announced a strategic collaboration with Caris Life Sciences, the leading molecular science and technology company actively developing and delivering innovative solutions to revolutionize healthcare. Utilizing its molecular profiling platforms, Caris will help identify and characterize patients for Zentalis’ clinical studies, initially for clinical trials investigating ZN-c3.

Corporate Highlights:

• In April 2022, the Company sold 953,834 of its common shares at a price of $26.21 per share to Pfizer for gross proceeds of approximately $25.0 million. Zentalis and Pfizer plan to jointly advance the clinical development of ZN-c3. In addition, Zentalis intends to use the net proceeds to fund ongoing and planned clinical trials, including studies of ZN-c3 and ZN-d5 and for working capital and general corporate purposes.
• Adam Schayowitz, Ph.D., MBA, Vice President & Medicine Team Group Lead for Breast Cancer, Colorectal Cancer and Melanoma, Pfizer, has joined Zentalis’ Scientific Advisory Board. Dr. Schayowitz will work closely with Zentalis’ senior management team to provide input on the Company’s clinical strategy.
• In March 2022, Zentalis announced it contributed $1 million to the Stand Up to Cancer (SU2C) Catalyst® program to support research that investigates certain small molecule inhibitors for the treatment of various cancer types.

First Quarter 2022 Financial Results

• Cash and Marketable Securities Position: As of March 31, 2022, Zentalis had cash, cash equivalents and marketable securities of $289.4 million. The Company believes that its existing cash, cash equivalents and marketable securities as of March 31, 2022, together with approximately $24.7 million of net proceeds from the April 2022 Pfizer equity investment, prioritization of the clinical development of ZN-c3 and ZN-d5, and budget reallocation, will be sufficient to fund its operating expenses and capital expenditures requirements into the first quarter of 2024.
• Research and Development Expenses: Research and development expenses for the three months ended March 31, 2022 were $46.1 million, compared to $38.4 million for the three months ended March 31, 2021. The increase was primarily due to increases in external research and development expenses related to Zentalis’ clinical product candidates as the Company advanced its clinical pipeline and personnel costs.
• General and Administrative Expenses: General and administrative expenses for the three months ended March 31, 2022 were $11.8 million, compared to $12.0 million during the three months ended March 31, 2021. The decrease in expenses was primarily attributable to allocable expenses and stock based compensation.
