Recent positive interim Phase 3 results from Moderna and Merck’s personalized mRNA cancer vaccine (intismeran autogene/mRNA-4157) combined with Keytruda, demonstrating reduced melanoma recurrence and metastasis risk, represent the primary catalyst behind the 87.5% market-implied probability for a BLA submission by June 30, 2027. The companies have initiated regulatory discussions, hold breakthrough therapy designation, and expect to share full data at an upcoming medical meeting, positioning a filing in late 2026 or early 2027. This timeline aligns with typical FDA review cycles for such programs and leaves substantial buffer before the deadline, though additional safety data requests remain a low-probability risk that could extend review without derailing submission.

Intismeran autogene refers to the individualized neoantigen therapy developed by Moderna and Merck and evaluated in the Phase 3 INTerpath-001 trial (NCT05933577), also known as mRNA-4157 and V940, together with any brand, trade, or nonproprietary name later assigned to that product, as well as any renamed or modified version that the relevant company or the FDA identify as the same product or a direct continuation of the V940/mRNA-4157 program.
A qualifying application must seek FDA licensure of intismeran autogene through a Biologics License Application (BLA). An original BLA or a resubmission of such a BLA following FDA action will qualify. The application may cover any indication.
A qualifying announcement must come from the relevant company submitting the BLA, the FDA, or authorized representatives thereof.
The submission must already have occurred at the time of the statement. A statement of intent, plan, guidance, or expected timing will not qualify.
If the FDA grants approval of intismeran autogene on or before June 30, 2027, 11:59 PM ET, this market will resolve to "Yes", whether or not a submission was separately disclosed.
The primary resolution source for this market will be official communications from the company submitting the BLA, the FDA, or authorized representatives thereof; however, a consensus of credible reporting may also be used.
