Why Immunome (IMNM) Is Down 8.2% After FDA Accepts Varegacestat NDA With Strong Phase 3 Data

• Immunome, Inc. previously announced that the FDA accepted its New Drug Application for varegacestat, an oral once-daily gamma secretase inhibitor for adults with desmoid tumors, assigning an April 28, 2027 PDUFA target action date based on the Phase 3 RINGSIDE trial.
• The NDA rests on RINGSIDE data showing a statistically significant and clinically meaningful improvement in progression-free survival versus placebo, with a very large reduction in the risk of disease progression or death.
• Against this backdrop, we will examine how FDA acceptance of the varegacestat NDA and its strong Phase 3 profile shape Immunome’s investment narrative.

What Is Immunome's Investment Narrative?

To own Immunome, you have to believe that varegacestat can anchor a viable oncology franchise while the earlier antibody drug conjugate programs mature. The NDA acceptance meaningfully sharpens the story: it locks in a PDUFA decision date and upgrades varegacestat from a late‑stage asset to a defined regulatory catalyst, even if commercial timelines remain out on the horizon. In the near term, that shifts attention toward regulatory review quality, potential label scope and any partnering or financing decisions made ahead of 2027, rather than binary trial risk. At the same time, the business is still small in revenue, running sizeable losses and recently exited key Russell indices, so capital needs and trading volatility stay front and center. The new FDA milestone fits squarely into that risk‑reward tradeoff.

However, one financing and dilution risk now looms larger that investors should not ignore. Despite retreating, Immunome's shares might still be trading above their fair value and there could be some more downside. Discover how much.
