Chart to Accompany (IMAGE) The Yates Network Caption * Scholar Rock identified three syngeneic mouse tumor models that recapitulate key features of human primary resistance to checkpoint inhibitor therapy: MBT-2 (bladder cancer), Cloudman S91 (melanoma) and the EMT-6 (breast cancer) mouse models. Combination treatment with SRK-181-mIgG1 and an anti-PD-1 therapy resulted in tumor regression or control and survival benefit across these three identified cancer models. This tumor response was also shown to be durable, where mice with no measurable tumor at treatment cessation remained tumor free.
