"We were pleased to report updated dose escalation data from our Phase 1/2 trial of ARV-110 in men with metastatic castration-resistant prostate cancer. These data demonstrated safety and showed an early efficacy signal in a heavily pretreated patient population, highlighting the potential benefit of our PROTAC platform. These data are a first for a targeted PROTAC protein degrader, and we are excited to report more mature data from our ARV-110 program, and to announce interim data from our ARV-471 Phase 1/2 trial, in the fourth quarter of 2020," said John Houston, Ph.D., President and Chief Executive Officer at Arvinas.

"As we look to the balance of 2020, we are in a stronger position than ever to lead the creation of an entirely new class of therapies that targets and degrades disease-causing proteins," added Dr. Houston.

Business Highlights and Recent Developments

The company presented early efficacy and updated safety data for ARV-110 at the 2020 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The data demonstrated that Arvinas’ PROTAC protein degrader ARV-110 had an acceptable safety profile (as of the data cut-off) and are the first to show early signs of clinical efficacy for ARV-110 in a heavily pretreated patient population.
The company enhanced its Board of Directors with the appointments of Linda Bain and Wendy Dixon, Ph.D.
Anticipated Milestones and Expectations

For the ARV-110 program, Arvinas expects to provide an update from its Phase 1/2 trial in the fourth quarter of 2020.
For the ARV-471 program, Arvinas expects to share Phase 1 dose escalation clinical data in the fourth quarter of 2020.
Arvinas expects to provide information about the advancement of additional programs in its robust preclinical pipeline in the second half of 2020.
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 2022.

Financial Highlights

Cash, Cash Equivalents, and Marketable Securities Position: As of June 30, 2020, cash, cash equivalents, and marketable securities were $242.7 million as compared with $280.9 million as of December 31, 2019. The decrease in cash, cash equivalents and marketable securities of $38.2 million for the first six months of 2020 was primarily related to cash used for operations of $43.2 million and the purchase of lab equipment and lease hold improvements of $3.2 million, partially offset by $4.0 million received from two collaborators, cash provided from the exercise of stock options of $2.6 million and changes in unrealized gain on marketable securities of $1.6 million.

Research and Development Expenses: Research and development expenses were $23.4 million for the quarter ended June 30, 2020, as compared with $16.0 million for the quarter ended June 30, 2019. The increase in research and development expenses of $7.4 million for the quarter was primarily related to increases in clinical trial and CMC expenses associated with our AR program of $2.3 million and our ER program of $1.0 million, in addition to increases in preclinical expenses of $4.1 million associated with exploratory programs and investments in platform research.

General and Administrative Expenses: General and administrative expenses were $8.8 million for the quarter ended June 30, 2020, as compared to $6.4 million for the quarter ended June 30, 2019. The increase of $2.4 million was primarily related to an increase in personnel and facility related costs of $2.2 million.

Revenues: Revenue was $5.7 million for the quarter ended June 30, 2020, as compared with $4.0 million for the quarter ended June 30, 2019. The increase of $1.7 million was primarily related to the collaboration and license agreement with Bayer that was initiated in July 2019. Revenues are 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.

Net Loss: Net loss was $25.2 million for the quarter ended June 30, 2020, as compared with $17.2 million for the quarter ended June 30, 2019. The increase in net loss for the quarter was primarily due to increased research and development expenses and increased general and administrative expenses.

About ARV-110

ARV-110 is an 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 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.
