Moderna (MRNA) shares climbed 98% and Merck (MRK) shares gained 9% in Wednesday trading after the companies said a late-stage trial of intismeran autogene in combination with Keytruda met the primary endpoint of recurrence-free survival and a key secondary endpoint of distant metastasis-free survival in patients with completely resected stage IIB-IV melanoma.
The combination demonstrated statistically significant and clinically meaningful improvements in both recurrence-free survival and distant metastasis-free survival compared with Keytruda alone, the companies said.
The trial will continue to evaluate other secondary endpoints, such as overall survival, the companies said.
Safety profiles of intismeran and Keytruda were consistent with previously reported results, with no new safety signals, the companies said.
