Peripheral blood mononuclear cells (PBMCs) from patients with PDAC and healthy donors were isolated and treated ex vivo with two AHR agonists (Carbidopa and Tapinarof) and one antagonist (BAY 2416964). Baseline AHR expression critically shapes the immune response to pharmacological modulation in PBMCs from PDAC patients. These findings suggest that AHR profiling may serve as a clinically relevant biomarker for stratifying patients and guiding personalized immunotherapy approaches for PDAC.

P1, N=47, Terminated, Bayer | Trial completion date: Dec 2025 --> Jan 2025 | Active, not recruiting --> Terminated; Last patient ongoing on treatment ended the study on 20th January 2025. Hence, the end of study was reached as defined in the protocol.
No differentially expressed genes (DEGs) were identified in wildtype cells exposed to 1 μM BAY2416964 for 24 h; however, 46.4% of DEGs overlapped between AhrKO and LT-BAY cells including gene regulated cell proliferation. Our data reveal long-term pharmacological inhibition of AHR by BAY2416964 closely resembles AHR loss in a mouse model of breast cancer.
