SHANGHAI & SUZHOU, China & GERMANTOWN, Md., May 6, 2022- Elpiscience Biopharmaceuticals, Inc. (“Elpiscience”), a clinical-stage biopharmaceutical company focused on developing next-generation immunotherapies to benefit cancer patients worldwide, today announced partner Compass Therapeutics reported positive interim 欧洲杯买球网 (also known as CTX-009) Phase 2 data in combination with paclitaxel in patients with biliary tract cancers (BTC). 欧洲杯买球网 is a bispecific antibody that simultaneously blocks Delta-like ligand 4/Notch (DLL4) and vascular endothelial growth factor A (VEGF-A) signaling pathways, which are critical to angiogenesis and tumor vascularization. 

In the study, 欧洲杯买球网 demonstrated:

•    42% overall response rate (ORR) based on 10 patients with Partial Responses (PRs), including 9 PRs confirmed by RECIST 1.1 and 1 PR pending confirmation 
•    Anti-tumor activity in previously treated patients with a clinical benefit rate (CBR) of 92% based on 22 patients with a PR or stable disease (SD) out of 24 enrolled patients 
•    Well-tolerated and preliminary safety profile consistent with prior studies

The Phase 2 study in patients with BTC is currently being conducted at four leading medical centers in Korea and Compass Therapeutics plans to open additional sites in the United States. In China, Elpiscience is currently enrolling patients in a 欧洲杯买球网 Phase 1/2 study for the treatment of unresectable locally advanced or metastatic colorectal cancer (CRC). 欧洲杯买球网 is currently the only clinical-stage bispecific antibody targeting VEGF and DLL4 in China. 

“We are encouraged by the impressive interim Phase 2 data in BTC patients from our partner,” said Steve Chin, Chief Medical Officer of Elpiscience. “欧洲杯买球网 in combination with paclitaxel showed a high ORR including responses in all four BTC subtypes and good overall tolerability consistent with prior studies. We believe in the clinical strategy to simultaneously target VEGF and DLL4 and look forward to our study findings in advanced CRC patients.”

About 欧洲杯买球网

欧洲杯买球网 is a bispecific antibody that simultaneously blocks Delta-like ligand 4/Notch (DLL4) and vascular endothelial growth factor A (VEGF-A) signaling pathways, which are critical to angiogenesis and tumor vascularization. Pre-clinical and early clinical data of 欧洲杯买球网 show that blocking both pathways provides robust anti-tumor activity across several solid tumors, including colorectal, gastric, cholangiocarcinoma, pancreatic, and non-small cell lung cancer. Partial responses to 欧洲杯买球网 as monotherapy have been observed in heavily pre-treated cancer patients, who were resistant to currently approved anti-VEGF therapies. 欧洲杯买球网 has completed a Phase 1 monotherapy dose-escalation and expansion study (NCT03292783). Phase 1b and Phase 2 clinical studies (NCT04492033) in combination with chemotherapy are ongoing. Elpiscience licensed 欧洲杯买球网 greater China rights from Compass Therapeutics in January 2021 and is conducting Phase 1/2 study in China for treatment in patients with unresectable locally advanced or metastatic colorectal cancer.
