Erasca, Inc. saw its stock price drop 48% after competitor Revolution Medicines challenged the intellectual property rights of Erasca's lead cancer drug candidate, ERAS-0015. The legal dispute alleges misappropriation of trade secrets and patent infringement related to RevMed's RMC-6236, leading to demands for Erasca to halt sales and stop making comparative claims. This caused a loss of over $2.8 billion in market value and prompted a shareholder investigation into whether Erasca misled investors about its patent protections. The case highlights risks in the competitive oncology drug market and may affect Erasca's future prospects.
