ARVN - Arvinas Reports Third Quarter 2021 Financial Results and Provides Corporate Update

NEW HAVEN, Conn., Nov. 03, 2021 (GLOBE NEWSWIRE) -- Arvinas, Inc. (Nasdaq: ARVN), a clinical-stage biotechnology company creating a new class of drugs based on targeted protein degradation, today reported financial results for the third quarter ended September 30, 2021 and provided a corporate update.

“The team at Arvinas has made a number of significant achievements throughout the year, from initiating multiple clinical trials to completing a potentially transformational collaboration with Pfizer, further establishing our leadership position in the field of targeted protein degradation,” said John Houston, Ph.D., chief executive officer at Arvinas. “We believe the upcoming presentation of data from the completed Phase 1 dose escalation study with ARV-471 for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer sets us up for a strong finish to what so far has been an important year of execution.”

“As we look ahead, our collaboration with Pfizer has enabled us to further evaluate the most efficient development pathway for ARV-471,” continued Dr. Houston. “In addition to initiating multiple planned Phase 3 studies with ARV-471 in 2022, we now intend to initiate the Phase 1b combination study with everolimus, potentially as part of a planned umbrella study with multiple combination agents with Pfizer, as well as the neoadjuvant study, in 2022. Additionally, we expect to present the full dose escalation data from the ARV-110 Phase 1 trial and an interim readout from the ARDENT Phase 2 expansion trial at ASCO Genitourinary Cancers Symposium in February 2022, an opportunity to showcase a more complete picture of the potential of ARV-110 in metastatic castration-resistant prostate cancer.”

Business Highlights and Recent Developments

• Initiated Phase 1b combination trial with ARV-110 and abiraterone for the treatment of metastatic castration-resistant prostate cancer (mCRPC).
• Completed global collaboration with Pfizer that included an upfront payment to Arvinas of $650 million, a $350 million equity investment from Pfizer, and $1.4 billion in potential milestone payments to co-develop and co-commercialize ARV-471 to the treatment of patients with ER+ breast cancer. Arvinas and Pfizer will equally share worldwide development costs, commercialization expenses, and profits.

Third Quarter Financial Results

Cash, Cash Equivalents, Restricted Cash and Marketable Securities Position: As of September 30, 2021, cash, cash equivalents, restricted cash and marketable securities were $1,549.0 million as compared with $688.5 million as of December 31, 2020. The increase in cash, cash equivalents, restricted cash and marketable securities of $860.5 million for the first nine months of 2021 was primarily related to cash received from the global Pfizer collaboration agreement to develop and commercialize ARV-471 (ARV-471 Collaboration Agreement) of $650.0 million, the equity investment by Pfizer of $350.0 million and proceeds from the exercise of stock options of $14.7 million, partially offset by cash used in operating activities of $133.9 million (net of $4.2 million received from two collaborators), professional fees associated with the global Pfizer collaboration and equity investment of $17.5 million, and the purchase of lab equipment and leasehold improvements of $2.8 million.

Research and Development Expenses: Research and development expenses were $40.6 million for the quarter ended September 30, 2021, as compared with $30.0 million for the quarter ended September 30, 2020. The increase in research and development expenses of $10.6 million for the quarter was primarily due to an increase in our continued investment in our platform and exploratory programs of $9.0 million and an increase in expenses related to our AR program (which includes ARV-110 and ARV-766) of $3.5 million, partially offset by a decrease in our ER program of $1.9 million, which includes the cost sharing of ARV-471 under the ARV-471 Collaboration Agreement with Pfizer.

General and Administrative Expenses: General and administrative expenses were $16.0 million for the quarter ended September 30, 2021, as compared with $9.3 million for the quarter ended September 30, 2020. The increase of $6.7 million was primarily due to an increase in personnel and facility related costs of $5.0 million and insurance and professional fees of $1.7 million.

Revenues : Revenues were $9.3 million for the quarter ended September 30, 2021 as compared to $7.6 million for the quarter ended September 30, 2020. Revenue is related to the ARV-471 Collaboration Agreement with Pfizer that was initiated in July 2021, the license and rights to technology fees and research and development activities related to the collaboration and license agreement with Bayer that was initiated in July 2019, the collaboration and license agreement with Pfizer that was initiated in January 2018, and the amended and restated option, license and collaboration agreement with Genentech that was initiated in November 2017. The increase in revenues of $1.7 million was primarily due to revenue from the ARV-471 Collaboration Agreement with Pfizer, partially offset by the addition of new targets added in 2020 under the January 2018 Pfizer Collaboration Agreement extending the revenue recognition period.

Net Loss: Net loss was $46.8 million for the quarter ended September 30, 2021, as compared with $30.8 million for the quarter ended September 30, 2020. The increase in net loss for the quarter was primarily due to increased research and development expenses and increased general and administrative expenses, partially offset by increased revenue.

About ARV-110
ARV-110 is an investigational orally bioavailable PROTAC ^® protein degrader designed to selectively target and degrade the androgen receptor (AR). ARV-110 is being developed as a potential treatment for men with metastatic castration-resistant prostate cancer.

ARV-110 has demonstrated activity in preclinical models of AR mutation or overexpression, both common mechanisms of resistance to currently available AR-targeted therapies.

About ARV-471
ARV-471 is an investigational orally bioavailable PROTAC ^® protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer.

In preclinical studies, ARV-471 demonstrated near-complete ER degradation in tumor cells, induced robust tumor shrinkage when dosed as a single agent in multiple ER-driven xenograft models, and showed superior anti-tumor activity when compared to a standard of care agent, fulvestrant, both as a single agent and in combination with a CDK4/6 inhibitor.

About ARV-766
ARV-766 is an investigational orally bioavailable PROTAC ^® protein degrader designed to selectively target and degrade AR. In preclinical studies, ARV-766 degraded all resistance-driving point mutations of AR, including L702H, a mutation associated with treatment with abiraterone and other AR-pathway therapies.

ARV-766 is being developed as a potential treatment for men with metastatic castration-resistant prostate cancer, and ARV-766 may also have applicability in other AR-driven diseases both in and outside oncology. ARV-766 has demonstrated activity in preclinical models of resistance to currently available AR-targeted therapies.

About Arvinas
Arvinas is a clinical-stage biopharmaceutical company dedicated to improving the lives of patients suffering from debilitating and life-threatening diseases through the discovery, development, and commercialization of therapies that degrade disease-causing proteins. Arvinas uses its proprietary PROTAC ^® Discovery Engine platform to engineer proteolysis targeting chimeras, or PROTAC ^® targeted protein degraders, that are designed to harness the body’s own natural protein disposal system to selectively and efficiently degrade and remove disease-causing proteins. In addition to its robust preclinical pipeline of PROTAC ^® protein degraders against validated and “undruggable” targets, the company has three clinical-stage programs: ARV-110 and ARV-766 for the treatment of men with metastatic castrate-resistant prostate cancer; and ARV-471 for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer.
