Clinical trial failure risk - ARV-471 or ARV-110 missing efficacy/safety endpoints would eliminate 70%+ of company value given pipeline concentration
Regulatory approval uncertainty - FDA may require additional trials or reject applications even with positive Phase 3 data, extending timeline 2-3 years
Competitive protein degradation platforms from Nurix, Kymera, C4 Therapeutics targeting similar mechanisms and indications
Patent expiration risk on core PROTAC technology (estimated 2030s) could erode competitive moat before commercialization
Established oncology therapies in prostate cancer (Xtandi, Zytiga, Erleada) and breast cancer (Ibrance, Verzenio) with proven efficacy create high bar for differentiation
Large pharma internal protein degradation programs (Roche, Bristol Myers Squibb) could bypass need for Arvinas partnerships
Next-generation ADCs and bispecifics targeting same patient populations may offer superior efficacy profiles
Cash burn of approximately $300M annually with $0.8B market cap creates dilution risk - likely needs financing within 12-18 months based on operating cash flow
Negative operating cash flow of $300M limits financial flexibility to expand pipeline or in-license complementary assets
Low market cap relative to development costs increases vulnerability to hostile acquisition or unfavorable partnership terms
