It's a good news, bad news scenario for exhausted T cells in chronic infections.

Seagen Inc. and Remegen Co. Ltd. will collaborate to exclusively develop and commercialize disitamab vedotin, a humanized antibody-drug conjugate (ADC) targeting HER2, giving Remegen the chance to earn up to $2.4 billion in total milestone payments.
While Aprea Therapeutics Inc.’s data disclosed July 21 from the phase II trial with eprenetapopt – also known as APR-246, a reactivator of mutant tumor suppressor protein p53 – plus azacitidine (AZA) whetted interest in taking aim at the “guardian of the genome,” the company’s fortune took an unexpected turn when the FDA smacked a partial clinical hold on work with the duo.
