Antitumor efficacy of 9MW2821 in CDXs. A–C, TGI evaluated in MDA-MB-468, NCI-H322M, HT1376 xenograft models. Xenograft mice (n = 8) were intravenously treated with 1, 3, or 10 mg/kg 9MW2821 or EV at 3 mg/kg or 10 mg/kg for one injection. All treatments were initiated on the day when the average tumor volume reached 100 to 150 mm3. The tumor inhibition rates are mean values of eight animals.
