"This past quarter, Zentalis continued to execute on its clinical development strategy, and we are pleased with the progress we have made to advance our lead program, ZN-c3, a potentially best-in-class WEE1 inhibitor," commented Dr. Anthony Sun, Chairman and Chief Executive Officer of Zentalis. "Most recently, we initiated a Phase 1/2 trial with ZN-c3 in combination with gemcitabine in patients with osteosarcoma, further supporting the broad potential of ZN-c3 in combination therapy settings. Before year-end, we plan to have a total of six ongoing trials investigating our WEE1 inhibitor and look forward to initiating our potentially registrational biomarker-driven Phase 2 trial shortly. Additionally, the foundational research on the discovery of ZN-c3 was published in the peer-reviewed Journal of Medicinal Chemistry, which reviews our objectives for designing ZN-c3 as a potentially safer and more selective WEE1 inhibitor and in turn, overcoming limitations seen with other candidates in development."

Continued Dr. Sun, "We remain on track with our anticipated clinical milestones and are eager to provide future updates on these efforts. Looking ahead, we are excited to host a virtual R&D Day on December 16, during which our management team and key opinion leaders will provide a review of new preclinical science across multiple programs and share clinical updates on ZN-d5 and ZN-e4."

Program Highlights:

In September 2021, Zentalis dosed the first patient in the Phase 1/2 study of ZN-c3 in combination with gemcitabine, a chemotherapy used to treat certain malignant tumors, in patients with relapsed or refractory osteosarcoma. Zentalis recently received orphan drug and rare pediatric disease designations from the U.S. Food and Drug Administration (FDA) for pediatric osteosarcoma. Zentalis expects to report initial results from this trial in the second half of 2022.
Enrollment is ongoing in the potentially registrational Phase 2 trial of ZN-c3 in women with recurrent or persistent USC. Following an end-of-Phase 1 meeting in July 2021, the FDA agreed in principle that ZN-c3 has the potential for an accelerated approval pathway based on the Phase 2 study design in USC.
In September 2021, research on the discovery of ZN-c3 was published in the Journal of Medicinal Chemistry. The paper reviews Zentalis’ objectives in designing ZN-c3 as a potentially safer and more selective WEE1 inhibitor, overcoming limitations seen with other WEE1 inhibitors.
In September 2021, Zentalis presented six poster presentations on the candidates: ZN-c3, a WEE1 inhibitor; ZN-c5, an oral selective SERD and ZN-d5, a BCL-2 inhibitor at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress.
Zentera Highlights:

In August 2021, Zentera, a Shanghai-based clinical-stage biopharmaceutical company formed by Zentalis, announced the completion of a $75 million Series B financing. Zentera plans to use the proceeds to advance the clinical development in China of three of Zentalis’ product candidates (ZN-c3, ZN-c5 and ZN-d5), as well as expand its pipeline through additional business development opportunities for China and global development.
Zentera received CTA acceptances in China for ZN-c3, ZN-c3 in combination, ZN-c5 and ZN-d5 and four clinical trials are ongoing.
Corporate Highlights:

In July 2021, Zentalis closed an underwritten follow-on offering of 3,565,000 shares of its common stock at a public offering price of $48.50 per share. The total net proceeds were approximately $162.2 million, after deducting underwriting discounts and commissions and offering expenses payable by Zentalis.
Third Quarter 2021 Financial Results

Cash and Marketable Securities Position: As of September 30, 2021, Zentalis had cash, cash equivalents and marketable securities of $366.8 million. We believe that our existing cash, cash equivalents and marketable securities as of September 30, 2021 will be sufficient to fund our operating expenses and capital expenditures requirements into the third quarter of 2023.
Research and Development Expenses: Research and development expenses for the three months ended September 30, 2021 were $54.0 million, compared to $24.7 million for the three months ended September 30, 2020. The increase of $29.3 million was primarily due to increases in external research and development expenses related to our clinical product candidates, as we advanced our clinical pipeline.
General and Administrative Expenses: General and administrative expenses for the three months ended September 30, 2021 were $8.9 million, compared to $10.1 million during the three months ended September 30, 2020. This decrease of $1.2 million was primarily attributable to a decrease of $0.6 million in legal fees and an increase in allocable overhead expenses to research and development expenses of $1.7 million, offset by an increase of $1.1 million of facilities and related permits/fees and licenses expenses.
Net Loss: Net loss was $10.5 million for the three months ended September 30, 2021, compared to $34.7 million for the three months ended September 30, 2020. The $24.2 million decrease in net loss was primarily the result of the gain on deconsolidation of Zentera recognized during the three months ended September 30, 2021, partially offset by increases in research and development expenses discussed above.
