DKK1 is important for canonical Wnt signaling and directly activates non-canonical Wnt signaling through pathways such as Rho and JNK. High DKK1 tissue concentrations in EC correlate with shorter overall survival (OS); increased activity of non-canonical signaling by DKK1 may be a reason for shortened OS. Targeting Wnt signaling pathways experimentally have led to modulation of cancer-related immunotherapy. DKN-01 (D) is a humanized monoclonal antibody recognizing DKK1 with preliminary safety and efficacy demonstrated in this study's dose escalation phase in pts with EC or GEJ at the MTD (300 mg) of D in combination with P. We continue to evaluate safety and efficacy of D in combination with P in pts with EC and GEJ cancer in multiple dose confirmation phases.
