Financial Guidance

Based on its current operating plan, Arvinas expects its cash, cash equivalents, and marketable securities will be sufficient to fund its planned operating expenses and capital expenditures into 2024.

First Quarter Financial Results

Cash, Cash Equivalents and Marketable Securities Position: As of March 31, 2021, cash, cash equivalents and marketable securities were $651.3 million as compared with $688.5 million as of December 31, 2020. The decrease primarily related to cash used to fund operations of $43.9 million, cash used to purchase fixed assets and leasehold improvements of $1.0 million and unrealized losses of $0.8 million, partially off-set by proceeds from two collaborators of $4.0 million and proceeds from the exercise of stock options of $4.5 million.

Research and Development Expenses: Research and development expenses were $34.9 million for the quarter ended March 31, 2021 as compared with $21.7 million for the quarter ended March 31, 2020. The increase in research and development expenses for the quarter of $13.2 million primarily related to Arvinas’ continued investment in its platform, exploratory and lead optimization programs of $8.3 million, its AR program of $1.5 million and estrogen receptor program (ER) of $3.4 million.

General and Administrative Expenses: General and administrative expenses were $12.3 million for the quarter ended March 31, 2021 as compared with $7.9 million for the quarter ended March 31, 2020. The increase in general and administrative expenses for the quarter of $4.4 million related to an increase of $3.6 million in personnel and facility related costs, including $1.8 million related to stock compensation expense, and insurance, taxes and professional fees of $0.8 million.

Revenues: Revenues were $5.5 million for the quarter ended March 31, 2021 as compared with $6.2 million for the quarter ended March 31, 2020 and was generated from 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 decrease in collaboration revenue of $0.7 million for the quarter was primarily related to a collaborator adding new targets that extended the period of revenue recognition for that collaboration agreement.   

Net Loss: Net loss was $41.0 million for the quarter ended March 31, 2021 as compared with $21.7 million for the quarter ended March 31, 2020. The increase in net loss for the quarter ended March 31, 2021 of $19.3 million primarily related to Arvinas’ continued investment in its platform, exploratory and lead optimization programs, its AR program, its ER program, and an increase in general and administrative costs.

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 two clinical-stage programs: ARV-110 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.
