Arvinas Reports Second Quarter 2019 Financial Results and Provides Corporate Update

NEW HAVEN, Conn. –August 5, 2019 – Arvinas, Inc. (Nasdaq: ARVN), a biotechnology company creating a new class of drugs based on targeted protein degradation, today reported financial results for the second quarter of 2019 and provided a corporate update.

“We made significant progress throughout the first half of 2019, highlighted by both clinical and corporate advances. We initiatedfirst-in-human studies withARV-110 in metastatic castration-resistant prostate cancer and received Fast Track designation from the U.S. Food and Drug Administration (FDA) for this indication. The FDA also cleared our IND forARV-471 in ER positive/HER2 negative breast cancer,” said John Houston, Ph.D., Chief Executive Officer of Arvinas. “The potential of our targeted protein degrader technology was further validated by our agreement with Bayer, which expands the application of our technology beyond human health and therapeutics to include agricultural applications.”

“In addition, we greatly enhanced our leadership strength with the addition of Ronald Peck, M.D., as our Chief Medical Officer and with the appointment of Leslie Norwalk, Esq., to our Board of Directors. Both are experienced executives with significant and relevant experience that will be instrumental in guiding Arvinas forward with a new class of drugs based on our proprietary targeted protein degradation platform,” added Dr. Houston.

Business Highlights and Recent Developments

• Strengthened the management team with the appointment of Ronald Peck, M.D. to the newly created position of Chief Medical Officer. Dr. Peck brings to Arvinas more than twenty years of clinical and drug development experience, most recently serving as Senior Vice President, Clinical Research at Tesaro, where he oversaw all clinical development efforts for the company’s entire pipeline, including Zejula^® (niraparib) and Tesaro’s immuno-oncology programs.

• Announced the appointment of Leslie Norwalk, Esq., to the Arvinas Board of Directors. Ms. Norwalk provides strategic counsel to a number of biotechnology companies and served in the George W. Bush Administration as the Acting Administrator for the Centers for Medicare & Medicaid Services (CMS).

• Presented preclinical data from the company’stau-targeted PROTAC^® protein degrader program at the Alzheimer’s Association International Conference (AAIC). In preclinical studies, thetau-targeted PROTAC^® protein degrader eliminated more than 95% of disease-causing (pathologic) tau protein in the brain, in a well-characterized mouse tauopathy model, following peripheral administration. The data further indicated that the tau protein degradation is dose- and concentration-dependent, signifying thetau-targeted PROTAC^® protein degrader effectively crosses the blood brain barrier.

• Entered into an agreement with Bayer to leverage Arvinas’ novel PROTAC^® protein degrader technology to develop new human therapeutics for patients with cardiovascular, oncological, and gynecological diseases. In addition, Bayer and Arvinas will jointly launch a new company to leverage Arvinas’ PROTAC^® technology for agricultural applications. The overall series of arrangements includes over $110 million in upfront cash and committed funding for the human disease collaboration, the agricultural joint venture, and a direct equity investment by Bayer in Arvinas.

• Announced that Arvinas’ lead PROTAC^® protein degrader,ARV-110, was granted Fast Track designation by the FDA for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC) whose disease has progressed after treatment with two or more systemic therapies.

• Announced that the FDA cleared the Company’s Investigational New Drug application (IND) forARV-471, an oral estrogen receptor (ER) PROTAC^® protein degrader, designed to selectively target ER for the treatment of patients with locally advanced or metastatic ER positive/HER2 negative breast cancer.

Anticipated Milestones and Expectations

• Present preliminary safety, tolerability, and pharmacokinetic data from the Phase 1 clinical trial ofARV-110 in the fourth quarter of 2019.

• Present additional clinical data from the Phase 1 trial ofARV-110 in the first half of 2020.

• Initiate a Phase 1 clinical trial ofARV-471 in patients with locally advanced or metastatic ER positive/HER2-negative breast cancer in the third quarter of 2019 and share preliminary clinical data in 2020.

Financial Guidance

Based on its current operating plan, Arvinas expects its cash, cash equivalents, marketable securities and proceeds from Bayer will be sufficient to fund its operating expenses and capital expenditure requirements into the second half of 2021.

Financial Highlights

Cash, Cash Equivalents, and Marketable Securities Position: As of June 30, 2019, cash, cash equivalents, and marketable securities were $159.2 million as compared to $187.8 million as of December 31, 2018. These amounts exclude proceeds from the private placement and collaboration agreement with Bayer, which closed on July 16, 2019 and will provide an additional $51.5 million. The decrease in cash, cash equivalents and marketable securities of $28.6 million in the first six months of 2019 was primarily related to net cash used in operating activities of $26.3 million, the purchase of lab equipment and lease hold improvements of $3.3 million partially offset by net cash provided by financing activities of $0.3 million and changes in unrealized gain on marketable securities of $0.5 million. During the six months ended June 30, 2019 we received $2.7 million from a collaborator and $1.0 million related to the exchange of research and development tax credits with the State of Connecticut. Our cash used to fund operations for the six months ended June 30, 2019 was $33.3 million.

Research and Development Expenses: Research and development expenses were $16.0 million for the quarter ended June 30, 2019, as compared to $10.3 million for the quarter ended June 30, 2018. The increase in research and development expenses for the quarter primarily related to expenses associated with the initiation of our Phase 1 clinical trial ofARV-110 andIND-enabling expenses associated withARV-471 as well as increased personnel and other expenses related to our platform research and exploratory programs research.

General and Administrative Expenses: General and administrative expenses were $6.4 million for the quarter ended June 30, 2019, as compared to $1.6 million for the quarter ended June 30, 2018. The increase in general and administrative expenses for the quarter was primarily related to increased employee expenses and other compliance costs associated with becoming a public company in the fourth quarter of 2018.

Revenues: Revenue was $4.0 million for the quarter ended June 2019, as compared to $3.4 million for the quarter ended June 30, 2018. Revenues are generated from the license and rights to technology fees and research and development activities related to 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.

Net Loss: Net loss was $17.2 million for the quarter ended June 30, 2019, as compared to $7.9 million for the quarter ended June 30, 2018. The increase in net loss for the quarter was primarily due to increased research and development expenses and increased general and administrative expenses.

AboutARV-110

ARV-110 is an orally-bioavailable PROTAC^® protein degrader designed to selectively target and degrade the androgen receptor protein (AR).ARV-110 is being developed as a potential treatment for men with metastatic castration-resistant prostate cancer (mCRPC).ARV-110 has demonstrated activity in preclinical models of AR mutation or overexpression, both common mechanisms of resistance to currently availableAR-targeted therapies. Arvinas believes the differentiated pharmacology ofARV-110, including its iterative mechanism of action, has the potential to translate into improved clinical outcomes for patients. Arvinas expects to present preliminary clinical data regardingARV-110 in the fourth quarter of 2019, and to present additional clinical data for the Phase 1 trial in the first half of 2020.

AboutARV-471

ARV-471 is an orally-bioavailable PROTAC^® protein degrader designed to target the estrogen receptor protein (ER). A Phase 1 clinical trial forARV-471 in patients with locally-advanced or metastatic ER positive/HER2-negative breast cancer is expected to begin in the third quarter of 2019 and preliminary clinical data is expected in 2020.
