NEW HAVEN, Conn., May 07, 2024 (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 first quarter ended March 31, 2024 and provided a corporate update.

"Our recently announced agreement with Novartis creates significant value for Arvinas and further validates our innovative PROTAC protein degrader platform and its potential to deliver important new treatment options for patients," said John Houston, Ph.D., Chairperson, President and Chief Executive Officer at Arvinas. "In addition to this strategic transaction, and together with Pfizer, we continued making meaningful progress advancing our Phase 3 clinical programs with vepdegestrant in ER+/HER2- metastatic breast cancer. During the quarter we also advanced ARV-102, our first PROTAC degrader with the potential to treat neurodegenerative diseases, into a Phase 1 clinical trial and we remain on track to initiate a first-in-human Phase 1 clinical trial with ARV-393, our BCL6 targeting PROTAC degrader, by the end of the second quarter. We also further strengthened our management team with key hires as we approach our first Phase 3 readout and continue progressing multiple ongoing and planned clinical-stage programs."

Financial Guidance
Based on its current operating plan, Arvinas believes its cash, cash equivalents, restricted cash and marketable securities as of March 31, 2024, is sufficient to fund planned operating expenses and capital expenditure requirements into 2027.

First Quarter Financial Results
Cash, Cash Equivalents and Marketable Securities Position : As of March 31, 2024, cash, cash equivalents, restricted cash and marketable securities were $1,174.8 million as compared with $1,266.5 million as of December 31, 2023. The decrease in cash, cash equivalents, restricted cash and marketable securities of $91.7 million for the three months ended March 31, 2024, was primarily related to cash used in operations of $92.1 million, unrealized losses on marketable securities of $1.3 million and leasehold improvements of $0.1 million, partially offset by proceeds from the exercise of stock options of $1.8 million.

Research and Development Expenses: Research and development expenses were $84.3 million for the quarter ended March 31, 2024, as compared with $95.3 million for the quarter ended March 31, 2023. The decrease in research and development expenses of $11.0 million for the quarter was primarily due to a decrease in expenses related to our AR program (which includes ARV-766 and bavdegalutamide (ARV-110)) of $8.2 million, our ER program (which includes the cost sharing of vepdegestrant under the Vepdegestrant (ARV-471) Collaboration Agreement) of $2.3 million and our platform and exploratory programs of $0.5 million.

General and Administrative Expenses: General and administrative expenses were $24.3 million for the quarter ended March 31, 2024, as compared with $24.9 million for the quarter ended March 31, 2023. The decrease of $0.6 million was primarily due to a decrease in personnel and infrastructure related costs of $2.4 million, partially offset by an increase in professional fees of $1.3 million and increases related to establishing our commercial operations of $0.6 million.

Revenues: Revenues were $25.3 million for the quarter ended March 31, 2024 as compared with $32.5 million for the quarter ended March 31, 2023. Revenue is related to the Vepdegestrant (ARV-471) Collaboration Agreement, the collaboration and license agreement with Bayer, the collaboration and license agreement with Pfizer, the amended and restated option, license and collaboration agreement with Genentech and revenue related to our Oerth Bio joint venture. The decrease in revenue of $7.2 million was primarily due to a decrease in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement of $12.5 million, a decrease of $1.8 million related to the conclusion of the performance period under the collaboration agreement with Genentech and a decrease of $1.1 million of previously constrained deferred revenue related to our Oerth Bio joint venture, offset in part by year over year increases in revenue of $5.5 million and $2.6 million from our collaboration and license agreements with Bayer and Pfizer, respectively, due to changes in estimates in 2023 of the performance period duration resulting from updated research timelines.

About Vepdegestrant (ARV-471)
Vepdegestrant is an investigational, orally bioavailable PROTAC protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with ER positive (ER+)/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Vepdegestrant is being developed as a potential monotherapy and as part of combination therapy across multiple treatment settings for ER+/HER2- metastatic breast cancer.

In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will share worldwide development costs, commercialization expenses, and profits.

Vepdegestrant has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the investigation of vepdegestrant for monotherapy in the treatment of adults with ER+/HER2- locally advanced or metastatic breast cancer previously treated with endocrine-based therapy.

About ARV-766
ARV-766 is an investigational orally bioavailable PROTAC protein degrader designed to selectively target and degrade the androgen receptor (AR). Preclinically, ARV-766 has demonstrated activity in models of wild type androgen receptor tumors in addition to tumors with AR mutations or amplification, both common potential mechanisms of resistance to currently available AR-targeted therapies.

About Arvinas
Arvinas is a clinical-stage biotechnology 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 four investigational clinical-stage programs: vepdegestrant (ARV-471) for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer; ARV-766 and bavdegalutamide for the treatment of patients with metastatic castration-resistant prostate cancer; and ARV-102 for the treatment of patients with neurodegenerative disorders.
