Exelixis announced new colorectal cancer trial collaboration with Merck alongside ASCO 2026 data presentations for CABOMETYX and zanzalintinib pipeline

Leadership read: The Merck collaboration is the operationally significant piece here, not the ASCO presentations. Presenting pipeline data at a major oncology congress is routine commercial positioning; co-designing a colorectal cancer trial with Merck commits Exelixis to shared protocol governance, co-enrollment infrastructure, and a data-sharing arrangement that will shape how zanzalintinib is positioned competitively for years. That is a materially different exposure than running a solo study, it embeds a large-pharma counterparty into scientific and commercial decisions at the trial-design stage, long before any readout. The related signals here are thin for biopharma specifically. Of the twelve partnership signals tracked in the last 90 days, only the Relation-GSK expanded collaboration is genuinely comparable, a clinical-stage company deepening a large-pharma co-development relationship. That is a sparse set, which limits pattern confidence. What it does reflect, consistent with the broader oncology-partnership cadence visible at ASCO cycles, is that mid-cap oncology platforms are increasingly using congress windows to announce or advance co-development structures rather than simply presenting data. Companies operating in this corridor, mid-cap oncology platforms co-developing assets with large-pharma partners, face concentrated demand for clinical development leadership with cross-partner trial governance experience, regulatory operations capable of managing multi-sponsor IND complexity, and commercial strategy functions that can maintain asset positioning independence even as co-development commitments deepen.
