Moderna and Merck Melanoma Therapy Achieves Primary Goal in Phase 3 Trial, Shares Surge
Moderna and Merck announced that their personalized mRNA cancer therapy, Intismeran Autogene combined with Merck’s Keytruda, met its primary endpoint in a Phase 3 melanoma trial. The trial, INTerpath-001, demonstrated statistically significant and clinically meaningful improvements in recurrence-free survival and distant metastasis-free survival for patients with high-risk stage IIB-IV melanoma whose tumors had been surgically removed. This marks the first positive Phase 3 readout for a personalized mRNA cancer therapy. Following the announcement, Moderna's shares surged by 93%, and Merck's shares increased by 7%. The companies plan to present detailed trial results at an upcoming international medical meeting and discuss regulatory submissions.
