Upfront Briefing

Bristol Myers is partnering with Janux on masked T cell engagers, another vote of confidence for “make T-cells safer” engineering (and a fresh set of comps for the spreadsheet).

Corcept put up an ovarian cancer overall survival win for relacorilant, improving the program’s outlook after a prior CRL overhang.

And the obesity arms race stays funded: Corxel raised up to $287M to push its oral GLP-1 forward.

The Big 3

1
Bristol Myers partners with Janux on masked T cell engagers (up to $850M)
  • Bristol Myers struck an up to $850M collaboration with Janux on a tumor-activated (“masked”) T-cell engager program, including up to $50M upfront/near-term payments, ~$800M in development/regulatory/commercial milestones, plus tiered royalties.
  • Why it matters: Another large-cap validation of “masked/conditional” T-cell engager design: it strengthens partnering comps for next-gen TCE platforms, tightens the gap to strategic takeout logic if early clinical safety/efficacy translate, and provides a fresh benchmark for how buyers are pricing de-risking engineering (vs. “plain vanilla” bispecifics).

Corcept reports ovarian cancer survival benefit for relacorilant
  • Corcept announced that its drug relacorilant extended patients' lives in a key ovarian cancer study, potentially improving the program's outlook after a prior CRL.
  • Why it matters: OS is the cleanest de-risking datapoint in ovarian cancer: it can pull the asset out from under the prior CRL shadow, expand strategic options (resubmission/label strategy vs. partnership), and re-anchor expectations for peak-sales and probability-of-success assumptions that flow into CORX's multiple.

3
Corxel raises up to $287M for oral GLP-1 development
  • Corxel secured up to $287 million to advance its oral GLP-1 development, intensifying competition in the obesity market and setting a high bar for new entrants.
  • Why it matters: This is a signal on capital intensity and competitive seriousness in oral incretins: big rounds will keep multiple shots on goal funded through Phase 2/3, raise the “evidence bar” for newcomers (weight loss + tolerability + manufacturability), and can pressure valuation narratives for anything oral-but-undifferentiated as the space consolidates around the best profiles.
