Experiment 1 Reporting the Activity Date of This ADC				[1]
Efficacy Data	Mean tumor colume&#177SEM	366.45&#17731.56 mm³	Moderate nectin-4 expression (nectin-4++)
Method Description	Female NSG mice between 5-6 weeks of age were injected subcutaneously withMDA-MB-468 cells with moderate nectin-4 expression, when tumors reached appproximately 150-250 mm^3, animals were matched by tumor volume into treatment or controls groups and dosing initiated (Day 0, n=8 per group). The test articles were given at a single dose (2 mg/kg) formulated with 5% dextrose. Tumors were measured biweekly until Day 71. Click to Show/Hide
In Vivo Model	MDAMB468 xenograft model
Experiment 2 Reporting the Activity Date of This ADC				[1]
Efficacy Data	Mean tumor colume&#177SEM	993.45&#177189.2 mm³	High nectin-4 expression (nectin-4 +++)
Method Description	Immune compromised female mice between 5-8 weeks of age with weight 18-20 grams were implanted unilaterally on the right flank with UM-UC-3 Nectin4 clone F7 cells with high nectin-4 expression, when tumors reached appproximately 150-250 mm^3, animals were matched by tumor volume into treatment or controls groups and dosing initiated (Day 0, n=8 per group). The test articles were given at a single dose (2 mg/kg) formulated with 5% dextrose. Tumors were measured biweekly until Day 40. Click to Show/Hide
In Vivo Model	UMUC3 Nectin-4 clone F7 xenograft model
