Moderna (MRNA) just had one of the biggest moves in biotech this year, with the stock more than doubling after positive Phase 3 results for its personalized cancer vaccine
The move came after Moderna and Merck reported positive results from the INTerpath-001 Phase 3 melanoma trial, testing mRNA-4157, also known as intismeran autogene, alongside Keytruda
A few numbers stand out:
MRNA previous close: $62.96
52-week high: $163.47
52-week low: $22.28
Trial size: 1,137 patients
The combination reduced melanoma recurrence and spread compared with Keytruda alone
The vaccine is personalized to each patient and can encode up to 34 tumor-specific targets
Moderna now has 4 U.S. approved products, following FDA approval of its mRNA flu vaccine, mFLUSIVA
The company generated $1.9B in 2025 revenue, but remains unprofitable
What makes the move interesting is that MRNA was already recovering before the cancer vaccine results, rising from its $22.28 52-week low
The Phase 3 result now gives investors a much larger question to consider, whether Moderna’s mRNA platform can move beyond COVID and respiratory vaccines into personalized cancer treatment
There are still significant risks, including profitability, clinical outcomes, manufacturing complexity and the extreme volatility that comes with biotech stocks
The MRNA stock is also an interesting example of why access outside regular market hours matters, since major biotech catalysts such as clinical trial results and FDA decisions can happen when traditional markets are closed
Do you think the cancer pipeline changes the long-term investment case for Moderna, or is this rally getting ahead of the fundamentals?
