Compass Therapeutics and ABL Bio Announce Presentation of CTX-009 Clinical Data as a Plenary Session of the 2021 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics

BOSTON--(BUSINESS WIRE)--#AACR--Compass Therapeutics, Inc. (OTC:CMPX), a clinical-stage, oncology focused biotechnology company developing proprietary immuno-modulatory and anti-angiogenic antibody therapeutics, and ABL Bio, Inc. (KOSDAQ: 298380), a clinical-stage biotech developing bispecific antibody technology for immuno-oncology and neurodegenerative diseases, announced today that the Phase 1 monotherapy dose escalation and expansion study data for CTX-009 (ABL001/ES104), a bispecific dual angiogenesis inhibitor targeting DLL4 and VEGF-A, has been selected for an oral plenary presentation at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, being held virtually on October 7-10, 2021. The oral presentation will include single agent safety, tolerability, exploratory DLL4 expression analysis, and clinical activity data for CTX-009 in heavily pre-treated patients with metastatic, anti-VEGF-resistant solid tumors, mainly of colorectal and gastric origin.

Oral Presentation Details:

Title: Phase Ia/Ib Dose-Escalation Study of ABL001 (CTX-009, Bispecific Antibody Targeting DLL4 and VEGF-A) as a Single Agent in Patients with Advanced Solid Tumors

Abstract Number: 4749

Session Title: Plenary Session 2: New Drugs on the Horizon I

Presenter: Jeeyun Lee, MD, Samsung Medical Center, Seoul, Korea

Date: October 8, 2021 at 10:45 a.m. EDT

About CTX-009

CTX-009 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 CTX-009 suggests 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 cancer patients, who were resistant to currently approved anti-VEGF therapies. CTX-009 has completed a Phase 1 monotherapy dose escalation and expansion study. Phase 1b and Phase 2 combination studies are ongoing.

About Compass Therapeutics

Compass Therapeutics, Inc. is a clinical-stage, oncology-focused biopharmaceutical company developing proprietary antibody-based therapeutics to treat multiple human diseases. Compass’ scientific focus is on the relationship between angiogenesis, the immune system and tumor growth. The company pipeline of novel product candidates is designed to target multiple critical biological pathways required for an effective anti-tumor response. These include modulation of the microvasculature via angiogenesis-targeted agents, induction of a potent immune response via activators on effector cells in the tumor microenvironment, and alleviation of immunosuppressive mechanisms used by tumors to evade immune surveillance. Compass plans to advance its product candidates through clinical development as both standalone therapies and in combination with proprietary pipeline antibodies based on supportive clinical and nonclinical data. The company was founded in 2014 and is headquartered in Boston, Massachusetts.

About ABL Bio

ABL Bio, Inc. (KOSDAQ: 298380) is a clinical-stage biotechnology company developing antibody therapeutics for immune-oncology and neurodegenerative diseases. With internal R&D and global partnerships, ABL has developed multiple bispecific antibody platforms, such as ‘Grabody-T,’ ‘Grabody-I’ and ‘Grabody-B’ and built an innovative pipeline of multiple clinical and pre-clinical stage drug candidates. In the oncology area, ABL has developed Grabody-T, a modular 4-1BB engaging platform that has demonstrated superior efficacy and safety. In the neurodegenerative disorder space, ABL has developed Grabody-B, which is designed to maximize blood-brain barrier (BBB) penetration. Grabody-B is applicable to various CNS targets across a plethora of neurological disorders, potentially providing a breakthrough to address the high unmet medical needs in neurodegeneration.
