On May 26, 2026 Adcendo ApS ("Adcendo"), a biotech company focused on the development of first- and best-in-class antibody-drug conjugates (ADCs) for the treatment of cancers with high unmet medical need, reported that it has entered into a clinical trial collaboration and supply agreement (the Agreement) with MSD (Merck & Co., Inc., Rahway, NJ, USA). ADCE-T02, a potential best-in-class topoisomerase-1 (Topo-1) inhibitor-based ADC targeting Tissue Factor (TF), will be evaluated in combination with KEYTRUDA (pembrolizumab), MSD’s anti-PD-1 (programmed cell death receptor-1) therapy, in a new Phase Ib study in patients with advanced solid tumors.

Dr. Lone Ottesen, Chief Medical Officer of Adcendo, said: "We are excited to work together with MSD on this new clinical trial combining ADCE-T02, our novel tissue factor-targeting ADC with pembrolizumab. Through this collaboration of potentially complementary mechanisms, we may be able to positively impact clinical outcomes for patients battling cancers where tissue factor is known to be overexpressed, such as head and neck squamous cell carcinoma, non-small cell lung cancer and cervical cancer."
Under the terms of the Agreement, MSD will provide pembrolizumab to Adcendo, which will be the sponsor of the Phase Ib clinical combination trial. Adcendo and MSD each retain all commercial rights to their respective compounds, including as monotherapy or as combination therapies.
Adcendo anticipates dosing the first patient in the Phase Ib combination study in 2H 2026 and will investigate the safety, tolerability and preliminary efficacy of escalating doses of ADCE-T02 in combination with standard dose pembrolizumab in patients with advanced solid tumors.
ADCE-T02 is currently being evaluated as a monotherapy in the Phase I Tiffany-01 (NCT06597721) clinical trial in patients with advanced solid tumors.
