Figure 4. XMT-1660 activity in ovarian tumors and PD-1 refractory breast tumor. A, Antitumor activity of XMT-1660 in OV2423 ovarian cancer PDX. Inset, B7-H4 IHC. B, Antitumor activity of XMT-1660 in CTG-1692 ovarian cancer PDX. Inset, B7-H4 IHC. C, Antitumor activity of XMT-1660 in mBR9013 MMTV-ERBB2-derived syngeneic tumor in FVB/NJ.
