Rhea-AI Filing Summary

TScan Therapeutics, Inc. (TCRX) reports that Amgen has elected to terminate in its entirety their Research Collaboration and License Agreement, which focused on using TScan’s target discovery platform to identify T‑cell antigens in Crohn’s disease. Amgen is exercising a contractual right to terminate with 90 days’ prior written notice, making the termination effective November 10, 2026, and TScan will incur no early termination penalty. TScan had previously received a $30.0 million non‑refundable upfront payment in 2023; the agreement also contemplated more than $500 million in success‑based milestones and tiered single‑digit royalties on future product sales. After termination, TScan does not expect future milestone or royalty payments from this collaboration unless Amgen or its affiliates or sublicensees continue to exploit product candidates, in which case applicable milestones and royalties would survive under the agreement’s terms.

FAQ

What did Amgen terminate in its collaboration with TScan Therapeutics (TCRX)?

Amgen elected to terminate in its entirety the Research Collaboration and License Agreement with TScan, covering use of TScan’s target discovery platform to identify T‑cell antigens in Crohn’s disease and Amgen’s exclusive worldwide rights to develop resulting product candidates.

When does the terminated Amgen–TScan (TCRX) collaboration officially end?

The termination becomes effective on November 10, 2026. Amgen exercised its right to terminate the agreement upon providing 90 days’ prior written notice, and TScan must wind down its activities under the then‑current research plan.

How much upfront cash did TScan Therapeutics (TCRX) receive from the Amgen deal?

TScan received a $30.0 million non‑refundable upfront payment in 2023 under the Amgen collaboration. This amount has already been paid; termination mainly affects potential future milestones and royalty streams rather than this upfront cash.

What potential milestone payments are affected by the Amgen–TScan (TCRX) termination?

The original agreement included success‑based milestone payments of over $500 million in aggregate. Following termination, TScan does not expect to receive these milestones unless Amgen or its affiliates or sublicensees continue to exploit product candidates from the collaboration.

Will TScan Therapeutics (TCRX) owe any penalties due to Amgen’s termination?

No early termination penalty is payable by TScan. Under the agreement’s terms, Amgen can terminate with 90 days’ written notice, and TScan’s main obligations are to promptly and efficiently wind down research activities under the current plan.

Can TScan Therapeutics (TCRX) still earn royalties from the former Amgen collaboration?

Royalties are only possible if Amgen, its affiliates or sublicensees continue to exploit product candidates created in the collaboration. In that case, applicable milestone and tiered single‑digit royalty obligations would survive according to the agreement’s terms.

Item 1.02

Termination of a Material Definitive Agreement.

On August 12, 2026, TScan Therapeutics, Inc. (the “Company”) received notice from Amgen Inc. (“Amgen”) of its election to terminate, in its entirety, the Research Collaboration and License Agreement, dated as of May 8, 2023, by and between the Company and Amgen (the “Collaboration Agreement”) pursuant to Amgen’s right under the Collaboration Agreement to terminate the agreement in its entirety upon 90 days’ prior written notice. Under the terms of the Collaboration Agreement, the termination will be effective 90 days following delivery of the notice, or November 10, 2026. No early termination penalty is payable by the Company in connection with the termination.

Under the Collaboration Agreement, the Company and Amgen collaborated to use the Company’s proprietary target discovery platform to identify antigens recognized by T-cells in patients with Crohn’s disease. The Collaboration Agreement granted Amgen an exclusive, worldwide, sublicensable license to develop and commercialize product candidates created and developed during the collaboration. The Collaboration Agreement provided for a non-refundable, upfront payment of $30.0 million to the Company, which was received in 2023, success-based milestone payments of over $500 million in the aggregate, and tiered single-digit royalty payments on net sales of products developed from the collaboration.

Upon receipt of written notice, the Company is obligated to use commercially reasonable efforts to promptly and efficiently wind down its activities under the then-current research plan. Upon the effective date of termination, the licenses granted under the Collaboration Agreement will terminate in accordance with its terms. Following termination, the Company does not expect to receive future milestone or royalty payments under the Collaboration Agreement unless Amgen, its affiliates or sublicensees continue to exploit product candidates, in which case applicable milestone and royalty obligations will survive in accordance with the terms of the Collaboration Agreement.

The foregoing description of the Collaboration Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Collaboration Agreement, a copy of which is filed as Exhibit 10.1 to the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2023, filed with the Securities and Exchange Commission on August 10, 2023, and incorporated by reference herein.
