The payment was triggered by contracted work orders for critical chemistry, manufacturing and controls (CMC) and production activities related to botensilimab (BOT) and balstilimab (BAL). These activities will allow Zydus to perform the initiation of its commercial supply of Agenus’ lead programs. They also include additional manufacturing work to satisfy regulatory requirements for BLA and MAA readiness, to build upon existing inventory in anticipation of increasing demand across clinical development programs, authorized early access pathways, and to support potential global commercialization.
This milestone marks the first operational activities between Agenus and Zylidac Bio LLC, the U.S.-based biologics manufacturing subsidiary of Zydus Life Sciences.
"This milestone reflects our commitment to progressing BOT and BAL to regulatory approval readiness, and to support our ongoing clinical development and paid compassionate access program needs," said Garo H. Armen, Ph.D., Chairman and Chief Executive Officer of Agenus. "As reimbursed access continues in France under the AAC framework and named patient programs expand in permitted countries and enrollment advances in the global BATTMAN Phase 3 trial, it is essential that we proactively align manufacturing capacity with anticipated demand. Our partnership with Zydus enables us to scale thoughtfully while maintaining capital discipline."
Agenus currently maintains sufficient cGMP clinical-grade BOT and BAL drug product inventory to support the ongoing BATTMAN Phase 3 trial, the ANSM-authorized French access program (AAC) program, paid named patient programs in select countries where permitted, and ongoing investigator-sponsored trials. The newly initiated manufacturing activities are designed to supplement existing supply and position the company to meet expanding demand across paid compassionate access, development and potential future commercial settings.
Under the collaboration agreement, up to $50 million in contingent payments may be triggered by BOT and BAL production orders. The $20 million payment announced today is contractually allocated specifically for production and CMC-related activities. This structure enables Agenus to execute critical manufacturing work in support of its development and access programs without additional capital expenditures impacting its cash position.
The strategic collaboration between Agenus and Zydus, originally announced in June 2025 and closed in January 2026, provides Agenus with long-term U.S.-based biologics manufacturing capacity to support BOT+BAL’s global development and potential commercialization.
