Moderna Stock Rally Was Telegraphed by Early Trial Signals
Moderna’s shares jumped after Merck and Moderna announced that their Phase III melanoma trial of intismeran autogene with KEYTRUDA met its endpoints, a readout that was effectively foreshadowed by pre-announced signals: a fully enrolled study, Merck covering about half the trial cost, and prior commentary that implied a big move could come. The stock rose to around $145, within a 52-week range of roughly $22–$174, despite Moderna’s weaker 2025 results and restructuring. The piece highlights how identifying funded, binary events in a pipeline—well before a readout—can inform portfolio strategies, as demonstrated by Moderna’s surge.
