By screening sensitive and non-sensitive tumor cell lines and PDX models, we identified a response-prediction biomarker signature. In upcoming clinical studies, this predictive biomarker signature will be evaluated for it’s potential to enrich for patients highly responsive to OMX-0407 therapy.
In summary, OMX-0407, a first-in-class oral SIK3 inhibitor, demonstrates potent monotherapy efficacy in a pro-inflammatory tumor setting by reshaping the immune compartment and accelerating tumor cell death. The ability of OMX-0407 to remodel an immunosuppressed TME in a generally cold tumor setting, harbors great clinical potential for OMX-0407 combination therapy with anti-PD-1/PD-L1 immune checkpoint blockade, specifically in patients with high unmet medical need who are resistant to current immune checkpoint inhibitor monotherapy.
