(Nasdaq: ARVN), a clinical-stage biotechnology company creating a new class of drugs based on targeted protein degradation, today reported financial results for the third quarter ended September 30, 2024, and provided a corporate update. “We maintained strong momentum across our portfolio in the third quarter and remain on track to report topline data from VERITAC-2, our Phase 3 clinical trial in metastatic breast cancer, in the fourth quarter of 2024 or the first quarter of 2025,” said John Houston, Ph.D., Chairperson, Chief Executive Officer and President at Arvinas. “In partnership with our colleagues at Pfizer, we are excited by the possibility of changing the treatment paradigm for ER+/HER2- breast cancer and look forward to sharing results from VERITAC-2 in the coming months.” “Our path to reaching our goal of becoming a multi-product, commercial-stage organization with a robust pipeline across several indications is clearly defined, and our novel PROTAC platform technology has the potential to enable opportunities across multiple therapeutic areas,” continued Dr. Houston. “We look forward to completing the multiple ascending dose portion of our Phase 1 clinical trial with ARV-102, our first PROTAC degrader with the potential to treat neurodegenerative diseases, and sharing data in 2025. We are also encouraged by the preclinical profile of ARV-393, our BCL6 PROTAC degrader currently being evaluated in a first-in-human Phase 1 clinical trial in patients with B-cell lymphomas. We look forward to sharing more about these programs in the coming months.” 3Q 2024 Business Highlights and Recent Developments Vepdegestrant Continued enrollment globally in multiple clinical studies of vepdegestrant in ER+/HER2- metastatic breast cancer. VERITAC-2: Phase 3 monotherapy clinical trial in patients with metastatic breast cancer (ClinicalTrials.gov Identifier: NCT05654623)TACTIVE-U: Phase 1b/2 combination umbrella trial evaluating combinations of vepdegestrant with abemaciclib, ribociclib, or samuraciclib (ClinicalTrials.gov Identifiers: NCT05548127, NCT05573555, and NCT06125522).TACTIVE-K: Phase 1/2 clinical trial with vepdegestrant plus Pfizer’s novel CDK4 inhibitor atirmociclib (ClinicalTrials.gov Identifier: NCT06206837) ARV-102: Oral PROTAC LRRK2 degrader In October, presented preclinical data at the 2024 Michael J. Fox Foundation Parkinson’s Disease Conference further supporting the potential of PROTAC-induced leucine-rich repeat kinase 2 (LRRK2) degradation as a potential treatment for patients with neurodegenerative diseases. New findings presented included data demonstrating: Orally delivered ARV-102 crosses the blood-brain barriers and degrades LRRK2 in the cerebrospinal fluid (CSF) of non-human primates (NHPs).Degradation of LRRK2 by ARV-102 induces changes in pathway (lysosomal and inflammation) biomarkers in the CSF of NHPs, which has not previously been demonstrated by kinase inhibitors of LRRK2.In murine tauopathy models, oral PROTAC LRRK2 degrader treatment led to ~50% pathologic tau reduction. Initiated the multiple ascending dose portion of the ongoing Phase 1 clinical trial in healthy volunteers. ARV-393: Oral PROTAC BCL6 degrader Continued recruiting patients in the first-in-human Phase 1 clinical trial in patients with B-cell lymphomas. Anticipated Upcoming Milestones and Expectations Vepdegestrant As part of Arvinas global collaboration with Pfizer, the companies plan to: Complete enrollment (4Q24) and announce topline data (4Q24/1Q25) for the VERITAC-2 Phase 3 monotherapy clinical trial in patients with metastatic breast cancer.Present initial safety and pharmacokinetic data from the TACTIVE-U sub-study (NCT05548127) of abemaciclib in combination with vepdegestrant at the San Antonio Breast Cancer Symposium (SABCS) in December 2024.Present data from the Phase 1 healthy volunteer pharmacokinetic trial of vepdegestrant in combination with midazolam to assess potential for drug-drug interaction at SABCS in December 2024 (NCT06256510).Continue enrollment of the ongoing Phase 1b/2 combination umbrella trial evaluating combinations of vepdegestrant with abemaciclib, ribociclib, or samuraciclib (TACTIVE-U; ClinicalTrials.gov Identifiers: NCT05548127, NCT05573555, and NCT06125522).Evaluate data from the study lead-in of the VERITAC-3 Phase 3 trial (NCT05909397) in patients with ER+/HER2- locally advanced or metastatic breast cancer (2H24).Continue enrollment and evaluate preliminary data from the ongoing clinical trial with vepdegestrant plus Pfizer’s novel CDK4 inhibitor atirmociclib (TACTIVE-K).Start Phase 3 combination trials in the first- and second-line settings (anticipated in 2025; pending emerging data and regulatory feedback). First-line setting with vepdegestrant plus atirmociclib or palbociclib.Second-line setting with vepdegestrant plus palbociclib and/or another CDK4/6 inhibitor. ARV-102: Oral PROTAC LRRK2 degrader Complete enrollment in the ongoing multiple ascending dose portion of a Phase 1 trial evaluating ARV-102 in healthy volunteersPresent data from the Phase 1 trial in 2025. ARV-393: Oral PROTAC BCL6 degrader Continue recruiting patients in the first-in-human Phase 1 clinical trial evaluating ARV-393 in patients with B-cell lymphomas. Novel PROTAC KRAS G12D degrader File an Investigational New Drug (IND) application in 2025. Financial GuidanceBased on its current operating plan, Arvinas believes its cash, cash equivalents, and marketable securities as of September 30, 2024, is sufficient to fund planned operating expenses and capital expenditure requirements into 2027. Third Quarter Financial Results Cash, Cash Equivalents, and Marketable Securities Position: As of September 30, 2024, cash, cash equivalents and marketable securities were $1,121.6 million as compared with cash, cash equivalents, restricted cash and marketable securities of $1,266.5 million as of December 31, 2023. The decrease in cash, cash equivalents and marketable securities of $144.9 million for the nine months ended September 30, 2024 was primarily related to cash used in operations of $158.1 million (net of $150.0 million received from the Novartis agreements), inclusive of a one-time cash termination fee in the amount of $41.5 million related to the termination of our laboratory and office space lease with 101 College Street LLC in August 2024 and the purchase of lab equipment and leasehold improvements of $1.5 million, partially offset by proceeds from the exercise of stock options of $7.7 million and unrealized gains on marketable securities of $7.2 million. Research and Development Expenses: Research and development expenses were $86.9 million for the quarter ended September 30, 2024, as compared with $85.9 million for the quarter ended September 30, 2023. The increase in research and development expenses of $1.0 million for the quarter was primarily due to an increase in compensation and related personnel expenses of $2.8 million, which are not allocated by program, partially offset by a decrease in external expenses of $2.2 million. External expenses include program-specific expenses, which decreased by $1.1 million, primarily driven by decreases in our ARV-766 and ARV-110 programs of $3.8 million and $1.6 million, respectively, partially offset by increases in our ARV-102 and ARV-393 programs of $2.5 million and $1.4 million, respectively, and our non-program specific expenses, which decreased by $1.1 million. General and Administrative Expenses: General and administrative expenses were $75.8 million for the quarter ended September 30, 2024, as compared with $22.6 million for the quarter ended September 30, 2023. The increase in general and administrative expenses of $53.2 million for the quarter was primarily due to a loss on the termination of our laboratory and office space lease with 101 College Street LLC of $43.4 million as well as increases in personnel and infrastructure related costs of $5.0 million, professional fees of $3.4 million and in developing our commercial operations of $1.2 million. Revenue: Revenue was $102.4 million for the quarter ended September 30, 2024 as compared with $34.6 million for the quarter ended September 30, 2023. Revenue for the quarter is related to the license agreement with Novartis, the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer, the collaboration and license agreement with Bayer and the collaboration and license agreement with Pfizer. The increase in revenue of $67.8 million was primarily due to revenue from the Novartis license agreement of $76.7 million, offset by a decrease in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer of $7.6 million related to timing differences in clinical trials and program expenses and a decrease in revenue from Bayer of $1.1 million related to the termination of the Bayer Collaboration Agreement in August 2024.
