Endoglin: Essential Non-VEGF Angiogenic Target Endoglin is expressed on endothelial cells and is essential for angiogenesis Selectively expressed on proliferating vessels in cancer and AMD; up-regulated following VEGF inhibition Unfavorable prognostic marker Attenuated endoglin expression causes Osler-Weber-Rendu syndrome which is associated with improved cancer survival (31% reduced risk of death) Persistent expression on tumor vessels results in progression despite VEGF inhibition, while knockdown of endoglin resensitizes tumors to VEGF inhibition Targeting VEGF and endoglin concurrently improves antitumor effects Endoglin is also expressed on myeloid derived suppressor cells (MDSCs) and potentiates PD-1/PD-L1 inhibition in preclinical models endoglin Normal Human Liver Human Liver Cancer Human AMD Membrane Angiosarcoma

Lead Indication: Angiosarcoma Angiosarcoma has a 5-year survival rate of less than 12%, which highlights the aggressive nature of the tumor when compared to a 5-year survival rate of approximately 56% for all soft tissue sarcoma1 Approximately 600 cases annually in the US and 1,200 in Europe, with a greater incidence in Asia2 Angiosarcoma can arise in any soft-tissue structure or viscera. About half of patients present with a primary cutaneous lesion. Risk factors include prior radiation exposure and chronic sun exposure. Treatment with chemotherapy (taxanes or doxorubicin) in the front line setting is associated with PFS of ~ 5 months and OS of less than 1 year3 Treatment with VEGF inhibitors in the second line setting is associated with PFS of 1.8 - 3.8 months and OS of less than 1 year 1www.cancerresearchuk.org 2Suveillance, Epidemiology, and End Results Program, NCI, www.seer.cancer.gov; RARECARE database, www.rarecare.eu 3Penel et al, JCO 2008; Italiano et al, Cancer 2012
