NEW HAVEN, Conn., July 30, 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 second quarter ended June 30, 2024, and provided a corporate update.

“During the second quarter, we continued making meaningful progress across our entire portfolio, with upcoming milestones that will further support our mission to improve patient lives with pioneering therapies from our revolutionary PROTAC^® protein degradation platform,” said John Houston, Ph.D., Chairperson, Chief Executive Officer and President at Arvinas. “The readout of VERITAC-2, our first Phase 3 clinical trial, will be a landmark event for Arvinas. We are on-track to complete enrollment in the fourth quarter of the year, with topline data anticipated in either the fourth quarter of 2024 or first quarter of 2025. If positive, we believe these results will support our first new drug application filing and our transition to a commercial-stage company, assuming regulatory approval.”

“We are well on our way to becoming a multi-product, commercial-stage organization with strong leadership and a robust pipeline across several indications,” continued Dr. Houston. “Our first PROTAC degrader with the potential to treat neurodegenerative diseases, ARV-102, was recently cleared to initiate the multiple ascending dose portion of our Phase 1 clinical trial. In addition, we initiated the first-in-human Phase 1 clinical trial in patients with B-cell lymphomas with our PROTAC BCL6 degrader ARV-393. I’m excited by the progress we have made and the ongoing confidence we have in our PROTAC platform, which was further validated by our recent strategic transaction with Novartis. We believe Novartis will accelerate and broaden the development of ARV-766 as a potential best-in-class treatment for patients with prostate cancer.”

Financial Guidance

Based on its current operating plan, Arvinas believes its cash, cash equivalents, restricted cash and marketable securities as of June 30, 2024, is sufficient to fund planned operating expenses and capital expenditure requirements into 2027.

Second Quarter Financial Results

Cash, Cash Equivalents, Restricted Cash and Marketable Securities Position: As of June 30, 2024, cash, cash equivalents, restricted cash and marketable securities were $1,234.2 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 $32.3 million for the six months ended June 30, 2024 was primarily related to cash used in operations of $36.0 million (net of $150.0 million received from the Novartis agreements), unrealized losses on marketable securities of $0.7 million and the purchase of lab equipment and leasehold improvements of $0.8 million, partially offset by proceeds from the exercise of stock options of $5.3 million.

Research and Development Expenses: Research and development expenses were $93.7 million for the quarter ended June 30, 2024, as compared with $103.4 million for the quarter ended June 30, 2023. The decrease in research and development expenses of $9.7 million for the quarter was primarily due to decreases in expenses related to our ER program (which includes the cost sharing of vepdegestrant under the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer) of $6.6 million and our platform and exploratory programs of $5.7 million, partially offset by an increase in our AR program (which includes ARV-766 and bavdegalutamide (ARV-110)) of $2.6 million.

General and Administrative Expenses: General and administrative expenses were $31.3 million for the quarter ended June 30, 2024, as compared with $25.7 million for the quarter ended June 30, 2023. The increase in general and administrative expenses of $5.6 million for the quarter was primarily due to an increase in personnel and infrastructure related costs of $4.0 million and professional fees of $1.6 million.

Revenues: Revenues were $76.5 million for the quarter ended June 30, 2024, as compared with $54.5 million for the quarter ended June 30, 2023. Revenue for the quarter is related to the license agreement and the asset purchase agreement with Novartis, the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer, the collaboration and license agreement with Bayer, the collaboration and license agreement with Pfizer, and revenue related to our Oerth Bio joint venture. The increase in revenue of $22.0 million was primarily due to revenue from the Novartis agreements, which were entered into during the quarter, of $45.4 million, offset by a decrease in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer of $22.2 million and a decrease of $1.3 million of previously constrained deferred revenue related to our Oerth Bio joint venture.
