Based on its current operating plan, Arvinas believes its cash, cash equivalents, restricted cash and marketable securities as of June 30, 2023, is sufficient to fund planned operating expenses and capital expenditure requirements into 2026.
Second Quarter Financial Results
Cash, Cash Equivalents and Marketable Securities Position: As of June 30, 2023, cash, cash equivalents, restricted cash and marketable securities were $1,044.3 million as compared with $1,210.8 million as of December 31, 2022. The decrease in cash, cash equivalents, restricted cash and marketable securities of $166.5 million for the six months ended June 30, 2023 was primarily related to cash used in operations of $172.9 million (net of $2.5 million received from two collaborators), leasehold improvements of $1.7 million and loss on the sale of marketable securities of $0.9 million, partially offset by unrealized gains on marketable securities of $7.0 million and proceeds from the exercise of stock options of $2.0 million.
Research and Development Expenses: Research and development expenses were $103.4 million for the quarter ended June 30, 2023, as compared with $75.3 million for the quarter ended June 30, 2022. The increase in research and development expenses of $28.1 million for the quarter was primarily due to increasing investment in our platform and exploratory programs of $5.4 million, as well as an increases our AR program of $7.4 million, which includes bavdegalutamide and ARV-766, and our ER program of $15.3 million, which is net of the cost sharing of vepdegestrant (ARV-471) under the global Pfizer collaboration agreement to develop and commercialize vepdegestrant that was initiated in July 2021 (Vepdegestrant (ARV-471) Collaboration Agreement).
General and Administrative Expenses: General and administrative expenses were $25.7 million for the quarter ended June 30, 2023, as compared with $24.3 million for the quarter ended June 30, 2022. The increase of $1.4 million was primarily due to an increase in professional fees of $2.0 million and increased investments in our commercial operations of $0.9 million, offset in part by reduced personnel and infrastructure related costs of $1.1 million and reduced insurance costs of $0.3 million.
Revenues: Revenues were $54.5 million for the quarter ended June 30, 2023 as compared with $33.8 million for the quarter ended June 30, 2022. Revenue is related to the Vepdegestrant (ARV-471) Collaboration Agreement, 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, the amended and restated option, license and collaboration agreement with Genentech that was initiated in November 2017 and revenue related to our Oerth Bio joint venture which was initiated in July 2019. The increase in revenues of $20.7 million was primarily due to an increase in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement totaling $24.2 million, partially offset by a net decrease in revenue of $1.8 million as the performance period under the collaboration agreement with Genentech has concluded and a decrease of $1.2 million of previously constrained deferred revenue related to our Oerth Bio joint venture.
Income Tax Expense: Income tax benefit was $0.3 million for the quarter ended June 30, 2023, as compared with an income tax expense of $3.4 million for the quarter ended June 30, 2022. Current year tax benefit was driven by expected benefits from state net operating loss carryback claims. Prior year tax expense was driven by revenue recognized in 2022 for tax purposes from the Vepdegestrant (ARV-471) Collaboration Agreement.
Loss from Equity Method Investment: Loss from equity method investment was $1.3 million for the quarter ended June 30, 2023, as compared with $2.5 million for the quarter ended June 30, 2022 due to decreased operating losses incurred by Oerth Bio.
Net Loss: Net loss was $66.6 million for the quarter ended June 30, 2023, as compared with $70.0 million for the quarter ended June 30, 2022. The decrease in net loss for the quarter was primarily due to increased revenue and interest income from our marketable securities, as well as decreased income tax expense, partly offset by increased research and development expenses and general and administrative expenses.
About bavdegalutamide (ARV-110) and ARV-766
Bavdegalutamide (ARV-110) and ARV-766 are investigational orally bioavailable PROTAC® protein degraders designed to selectively target and degrade the androgen receptor (AR). Bavdegalutamide and ARV-766 are being developed as potential treatments for men with prostate cancer. Preclinically, both investigational agents have demonstrated activity in models of wild type tumors in addition to tumors with AR mutation or amplification, both common mechanisms of resistance to currently available AR-targeted therapies.
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 early and locally advanced or metastatic ER positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Use of vepdegestrant in the ongoing and planned clinical trials will continue to monitor and evaluate patient safety and anti-tumor activity.
In preclinical studies, vepdegestrant demonstrated up to 97% ER degradation in tumor cells, induced tumor shrinkage when dosed as a single agent in multiple ER-driven xenograft models, and showed increased 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. In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will equally share worldwide development costs, commercialization expenses, and profits.
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 three investigational clinical-stage programs: bavdegalutamide and ARV-766 for the treatment of men with metastatic castration-resistant prostate cancer; and vepdegestrant (ARV-471) for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer.
