What Erasca, Inc. told the SEC could break it.
Erasca's disclosures are those of a pre-revenue biotech increasingly entangled with US-China tensions. It has no product revenue, posted a $124.5 million net loss in 2025 against an $892.2 million accumulated deficit, and expects losses to grow as it advances clinical development. A recurring theme is its dependence on China: it licenses a drug candidate from China's Joyo and relies on foreign CROs and CMOs, so US BIOSECURE Act 'biotechnology company of concern' designations, sanctions, tariffs or US-China retaliation could disrupt its development. Relatedly, it must share trade secrets and know-how with partners and contractors in countries at heightened risk of theft, including by state-affiliated actors.

Regulatory & policy
- BIOSECURE Act / reliance on China CROs & CMOsmedium
Erasca licenses ERAS-0015 from China's Joyo and relies on foreign CROs/CMOs; U.S. BIOSECURE Act 'biotechnology company of concern' designations, sanctions, tariffs or U.S.-China retaliation could disrupt its development.
“If the foreign CROs and CMOs we rely on become subject to trade restrictions, sanctions, increased tariffs or other regulatory requirements by the US government (including designation as a “biotechnology company of concern” under the US BIOSECURE Act), or if the US or Chinese government take retaliatory actions due to recent or increased tensions between the US and China, it may have the potentia”
