Galapagos and Adaptimmune sign clinical collaboration agreement with an option to exclusively license Adaptimmune’s TCR T-cell therapy candidate, uza-cel, in head & neck cancer and potential future solid tumor indications

Galapagos and Adaptimmune announced today that they have entered into a clinical collaboration agreement with an option to exclusively license Adaptimmune’s next-generation TCR T-cell therapy (uza-cel) targeting MAGE-A4 for head & neck cancer and potential future solid tumor indications, using Galapagos’ decentralized cell manufacturing platform.

Uza-cel is a next-generation clinical-stage engineered TCR T-cell therapy developed by Adaptimmune, targeting the MAGE-A4 cancer antigen expressed in various solid tumors. Uza-cel is engineered to express the CD8α co-receptor alongside the engineered TCR that targets MAGE-A4. Data indicate that co-expression of CD8α may broaden and increase the immune response against solid tumors.1

The Adaptimmune sponsored Phase 1 SURPASS trial with centrally manufactured uza-cel has shown encouraging results in head & neck cancer with an overall response rate of 80%. Initial in vitro results suggest that uza-cel, produced on Galapagos’ decentralized manufacturing platform, yields early phenotype T-cells that could improve efficacy and durability compared to uza-cel centrally manufactured on Adaptimmune’s platform.2 In addition, Galapagos’ decentralized manufacturing platform offers the potential for the delivery of fresh, fit cells with a vein-to-vein time of seven days in a patient population in which rapid access to treatment is vital.

Dr. Paul Stoffels3, Galapagos’ Chief Executive Officer and Chairman: “We are excited to partner with Adaptimmune, a pioneer in TCR T-cell therapy, as this fully aligns with our strategic vision to advance novel cell therapies. This collaboration enables us to expand our oncology cell therapy portfolio to include treatments for solid tumors and next-generation therapies, leveraging our innovative, decentralized cell therapy manufacturing platform. For patients with head & neck cancer, an area with significant unmet medical needs, this collaboration offers the promise for faster access to a potentially transformative treatment.”

Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer: “Data with uza-cel from our Phase 1 SURPASS trial has demonstrated compelling early results in ovarian, bladder, and head & neck cancers. In head & neck cancer, we have seen reductions in target lesions across all five patients treated to date, and there have been four confirmed partial responses. Combining uza-cel with Galapagos’ unique decentralized manufacturing platform is a natural synergy and has the potential to deliver an even more effective TCR T-cell therapy for people with critical late-stage cancers.”

Under the terms of the agreement, Adaptimmune will receive an upfront exclusivity payment of $70 million, plus $15 million in R&D funding at signing. A further $15 million in R&D funding will follow subject to the start of dosing in the proof-of-concept trial. Adaptimmune will be responsible for the clinical proof-of-concept trial in head & neck cancer and the supply of the vector for the manufacturing of uza-cel. Galapagos will be responsible for the delivery of fresh uza-cel product for the head & neck cancer proof-of-concept trial using its innovative, decentralized cell therapy manufacturing platform.

Adaptimmune will retain the right to develop, manufacture, commercialize, and otherwise exploit uza-cel for platinum-resistant ovarian cancer (currently being developed in the SURPASS-3 trial).

Following completion of the proof-of-concept trial, Galapagos has an exclusive option to license global rights to uza-cel for a maximum of $100 million, depending on the number of indications in relation to which the option is exercised. In addition, Adaptimmune is eligible to receive development, regulatory and sales milestone payments of up $465 million, unless the agreement is terminated, and tiered royalties on net sales in the mid-single to low-double digit range.
