LEXINGTON, Mass. And MARLOW, UK – [April 21, 2026] – Agenus Inc. (Nasdaq: AGEN), a leader in immuno-oncology innovation, and BAP Pharma, a global medicines access and clinical trial supply company, today announced the exclusive appointment of BAP Pharma as Agenus’ global partner for their botensilimab (BOT) plus balstilimab (BAL) authorized global access programs.

The partnership supports compliant, patient-focused access to BOT+BAL through authorized pathways where permitted by local regulations. Effective immediately, BAP Pharma will serve as Agenus’ exclusive partner for the coordination of BOT+BAL global access program operations, including program requests, case coordination, distribution logistics, and related payment processing.

These programs include France’s Autorisation d’Accès Compassionnel (AAC) pathway as well as paid named-patient programs (NPP) in select countries outside the United States. As previously disclosed, Agenus has received more than 270 physician inquiries from more than 30 countries across these pathways.

“Physicians around the world continue to express strong interest in BOT+BAL through authorized early access pathways, informed by the growing body of clinical data generated to date and the urgent need for better options for patients with serious cancers. Our exclusive partnership with BAP Pharma strengthens the infrastructure behind these programs and reinforces our commitment to act responsibly and efficiently. Where access is permitted, we believe we have a moral responsibility to help enable appropriate, compliant access for patients whose physicians are seeking new alternatives.”

Garo H. Armen, PhD, Chairman and CEO of Agenus.

France’s AAC program provides hospital-based, fully government-reimbursed access to BOT+BAL for eligible patients with MSS metastatic colorectal cancer without active liver metastases, platinum-resistant or platinum-refractory ovarian cancer, and certain advanced soft-tissue sarcomas under a nationally defined protocol. These patients typically have advanced cancers for which standard treatment options have been exhausted. Outside France, BOT+BAL may be available in select countries through paid NPPs initiated by treating physicians and governed by local regulations, including where a treating physician determines that BOT+BAL is an appropriate option for an individual patient based on the clinical data generated to date, medical need, and applicable local requirements.

Physician interest in BOT+BAL access has broadened across regions. Patients have already been treated through regulatory-authorized paid named-patient programs in multiple countries across South and Central America and Europe, including the United Kingdom, Switzerland, Greece, Brazil, and Argentina, with expansion into Spain where permitted by local regulations.

Under the collaboration, BAP Pharma will coordinate Agenus’ global access operations across these programs. BAP Pharma brings extensive global medicines access experience, a professional and responsive approach to physician and site engagement, and the operational rigor required to streamline logistics, strengthen regional coordination, and support treating physicians navigating country-specific regulatory frameworks.

“BAP Pharma’s team has demonstrated the professionalism, responsiveness, and operational rigor that are essential in supporting global access programs. Their approach aligns well with our commitment to physicians and patients seeking access through authorized pathways, and we believe this partnership will help strengthen the experience for health care teams around the world.”

Kamel Djazouli, M.D., Head of Medical Affairs of Agenus

Agenus’ early access efforts complement its ongoing clinical development strategy for BOT+BAL, including the global Phase 3 BATTMAN trial in refractory MSS/pMMR metastatic colorectal cancer. Until marketing authorization is granted, BOT+BAL is available only through clinical trials and authorized access pathways where permitted and available under local regulatory frameworks.
