Portfolio-level costs (adjusting for ~10% success rate) without organoids ~$2.5 B and with organoids $1.8 B.
With an estimated capital efficiency gain of ~30-40% i.e. $400 M per program

The lead molecule, Petosemtamab, was then validated against an expanded panel of 80 patient-derived organoids to predict clinical efficacy and guide its progression to the clinic. Today, a global Phase 3 trial (LiGeR-HN1, NCT06525220) is evaluating Petosemtamab in combination with pembrolizumab for the first-line treatment of PD-L1-positive recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). The U.S. FDA has granted the combination Breakthrough Therapy Designation, and Merus is also exploring Petosemtamab’s potential in additional indications, including colorectal cancer.
