[{"type":"text","content":"BOSTON, Jan. 20, 2022 (GLOBE NEWSWIRE) -- Compass Therapeutics, Inc. (Nasdaq: CMPX), a clinical-stage biopharmaceutical company developing proprietary antibody-based therapeutics to treat cancer, today announced that the U.S. Food and Drug Administration (FDA) has cleared its IND application for CTX-009, enabling the company to initiate a global Phase 2 clinical trial for CTX-009 in patients who have advanced Biliary Tract Cancers (BTC) in the United States and South Korea. Compass plans to include the existing Phase 2 in South Korea in this global study, allowing it to expand the ongoing study of CTX-009 under this IND. CTX-009 is a bispecific antibody that simultaneously targets Delta-like ligand 4 (DLL4) and vascular endothelial growth factor A (VEGF-A). “We are extremely pleased to announce today the FDA has accepted our IND application for CTX-009. We thank the reviewers at the FDA for their review and comments on the Phase 2 study design,” said Thomas J. Schuetz, MD, PhD, CEO and Scientific Founder of Compass. “The ongoing Phase 2 study in South Korea will now be expanded to a global study with the opening of US clinical sites in Q2. We believe that CTX-009 has the potential to be an important new therapy for patients with biliary tract cancers, including cholangiocarcinomas,” added Dr. Schuetz. About CTX-009 CTX-009 is a bispecific antibody that simultaneously targets Delta-like ligand 4 (DLL4) and vascular endothelial growth factor A (VEGF-A). This next generation angiogenesis inhibitor has completed a Phase 1 dose escalation and expansion study, and a Phase 1b study in combination with chemotherapy. As a monotherapy, CTX-009 demonstrated clinical benefit in heavily pre-treated patients who had progressed after prior therapy with chemotherapy regimens containing VEGF blockers such as bevacizumab and ramucirumab. Several clinical responses were observed in patients with advanced colorectal cancer and in patients with gastric cancer. Additional durable responses were also observed in the combination study with chemotherapy in patients with cholangiocarcinoma. About the Phase 2 Clinical Trial A Phase 2 study was initiated in Q1 2021 in South Korea evaluating CTX-009 in combination with paclitaxel in patients with advanced Biliary Tract Cancers (cholangiocarcinoma) in whom multiple prior regimens had failed. The study is a S...
