Compass Therapeutics Receives FDA Fast Track Designation for the Investigation of CTX-009 in Combination with Paclitaxel for the Treatment of Patients with Metastatic or Locally Advanced Biliary Tract Tumors That Have Been Previously Treated

  • CTX-009, the Company’s bispecific DLL4/VEGF-A antibody, in combination with paclitaxel, has shown promising clinical responses in patients with advanced biliary tract cancer (BTC) in its Phase 2 study
  • Top-line data readout for COMPANION-002, the Company’s randomized Phase 2/3 BTC U.S. study, is expected by the end of 2024

Excerpt from the Press Release:

BOSTON, April 25, 2024 (GLOBE NEWSWIRE) — Compass Therapeutics, Inc. (Nasdaq: CMPX), a clinical-stage, oncology-focused biopharmaceutical company developing proprietary antibody-based therapeutics to treat multiple human diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to CTX-009, the Company’s bispecific DLL4/VEGF-A antibody, in combination with paclitaxel for the treatment of patients with metastatic or locally advanced BTC that have been previously treated.

“We are delighted that CTX-009 has received FDA Fast Track Designation highlighting the large unmet need in patients with advanced BTC where current therapies have low, single digit response rates, and limited effect on patient survival,” said Thomas Schuetz, MD, PhD, Co-founder, President of R&D, and Vice Chairman of the Compass board. “Our current study is evaluating the combination of CTX-009 with paclitaxel following the observation of nine partial responses in 24 patients treated in our Phase 2 study, leading to an overall response rate of 37.5% (n= 9/24), a median progression free survival of 9.4 months and a median overall survival of 12.5 months. Compass remains on track to complete enrollment by mid-year and reporting top-line data by year end.”

About CTX-009

CTX-009 is a bispecific antibody that simultaneously blocks Delta-like ligand 4 (DLL4) and vascular endothelial growth factor A (VEGF-A) signaling pathways, which are critical to angiogenesis and tumor vascularization. Preclinical and early clinical data of CTX-009 suggest that blockade of 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 CTX-009 as a monotherapy have been observed in heavily pre-treated patients with cancer who were resistant to approved anti-VEGF therapies.
