Agenus IncCompany secured up to $340M in private placement to fund colon cancer trial, driving shares up ~100%.

Agenus shares jumped about 100% on Monday after the biotechnology company announced an oversubscribed private placement of up to $340 million to support development of its botensilimab and balstilimab immunotherapy combination in microsatellite-stable colon cancer. The financing includes approximately $85 million in upfront gross proceeds, with an additional potential $255 million available through the full exercise of purchase warrants. The transaction was led by Commodore Capital, with participation from RA Capital Management, TCGX, Invus, and Ligand Pharmaceuticals. Proceeds will be used to advance ROBBIN, a planned registrational Phase 3 trial evaluating neoadjuvant BOT+BAL in previously untreated high-risk Stage II and Stage III MSS colon cancer, with the company expecting the financing, assuming full warrant exercise, to provide funding through the end of 2031. The trial is designed to enroll 850 patients globally and will compare neoadjuvant BOT+BAL followed by standard of care against standard of care alone, with event-free survival as the primary endpoint.
