First-in-Class FDA Approval of VEPPANU (vepdegestrant)
FDA approved VEPPANU for ESR1-mutant, ER+/HER2- advanced breast cancer — the first-ever heterobifunctional PROTAC degrader approval. Arvinas and Pfizer entered a global licensing agreement with Rigel for commercialization, development and manufacturing; Arvinas/Pfizer to split economics 50/50 for the out-license. Approval validates platform and de-risks modality.
Rigel Out-License and Near-Term Financial Upside
Out-license to Rigel includes upfront and near-term milestones and an approval milestone expected later in the year that will provide cash inflows; Arvinas expects milestone/royalty economics to be shared with Pfizer (50/50) for U.S. approval-related payments.
Strong Balance Sheet and Cash Runway
Cash, cash equivalents and marketable securities were $614.9 million at 3/31/2026 (down from $685.4M at end of 2025). Company reiterates cash runway into the second half of 2028 to fund operations and key data milestones.
Material Cost Reductions and Expense Discipline
Non-GAAP R&D decreased by $25.0 million (a 32% reduction) and non-GAAP G&A decreased by $10.1 million (a 44% reduction) versus prior year. Total non-GAAP expenses were $67.3 million, down $35.1 million vs prior year, reflecting completed cost reduction programs and a new 2026 cost structure.
ARV-102 (LRRK2) Phase 1 Biomarker Success and Tolerability
Phase 1 data showed approximately ≥50% reductions in CSF LRRK2 by day 14 (sustained through day 28) in Parkinson's disease patients, with dose-dependent reductions in downstream biomarkers (CD68, GPNMB). ARV-102 was generally well tolerated with no serious adverse events through 28 days.
ARV-806 (KRAS G12D) Preclinical Potency and Rapid Enrollment
Preclinical data show ~25–40x greater potency versus clinical-stage KRAS G12D inhibitors/degraders and durable degradation (>90% for 7 days after single dose). Phase 1 dose-escalation enrollment completed well ahead of schedule; initial clinical data expected later this year.
ARV-393 (BCL6) Early Clinical Responses and Combination Strategy
Ongoing Phase 1 monotherapy dose escalation in relapsed/refractory B- and T-cell lymphomas with early responses observed at exposures below predicted efficacious levels and robust BCL6 degradation. Combination trial with glofitamab in diffuse large B-cell lymphoma has been initiated.
Multiple Discovery-to-Clinic Programs and Translational Track Record
Four Phase 1 clinical programs ongoing (plus additional programs planned), over 2,000 patients/volunteers dosed historically, and promising discovery programs (ARV-6723 HPK1 IO and oral pan-KRAS) progressing toward clinical entry later this year — demonstrating platform breadth.
