• Compass Therapeutics Announces First Patient Dosed in the Phase 1b CTX-471 Combination Trial with KEYTRUDA® (pembrolizumab)

    المصدر: Nasdaq GlobeNewswire / 01 ديسمبر 2022 07:30:00   America/Chicago

    • First patient dosed in Phase 1b study of CTX-471 in combination with KEYTRUDA® in cancers of the lung, head and neck, as well as melanoma

    • In the first part of this Phase 1b study, CTX-471 was dosed as a monotherapy and demonstrated signs of activity in patients with various metastatic or locally advanced solid tumors who initially benefited from a checkpoint inhibitor
    • The study is designed to evaluate the potential of CTX-471 in combination with KEYTRUDA® to address treatment resistance and improve patient outcomes
    • CTX-471 is a fully human IgG4 agonistic antibody that binds to a unique epitope of the CD137 receptor that has a co-stimulatory effect on T-Cells and NK Cells, two important components of the innate immune system

    BOSTON, Dec. 01, 2022 (GLOBE NEWSWIRE) -- Compass Therapeutics, Inc. (“Compass”; Nasdaq: CMPX), a clinical-stage, oncology-focused biopharmaceutical company developing proprietary antibody-based therapeutics to treat multiple human diseases, today announced that the first patient has been dosed in the Phase 1b study of CTX-471 in combination with KEYTRUDA®, Merck’s anti-PD-1 therapy, in patients with advanced solid tumors.

    CTX-471 is supplied by Compass, which is also the sponsor of this study, and KEYTRUDA® will be supplied by Merck (known as MSD outside the United States and Canada) under a clinical collaboration and supply agreement between the companies. This study enrolls patients with metastatic or locally advanced non-small cell lung cancer, melanoma, small cell lung cancer, mesothelioma, and head and neck cancer that have progressed after treatment with a checkpoint inhibitor. Patients enrolled in the study will be treated with CTX-471 in combination with KEYTRUDA® with the goal of restoring response.

    “We are very pleased to be making progress on our CTX-471 clinical program with dosing of the first patient in the combination arm with KEYTRUDA®,” said Thomas Schuetz, M.D., Ph.D., Chief Executive Officer and Scientific Founder of Compass. “We are excited about the potential to build upon the responses observed with CTX-471 monotherapy across multiple tumor types and address significant unmet need in the field of cancer immunotherapy.”

    CTX-471 is a next generation, CD137 agonist, fully human, IgG4, with optimized affinity for an agonistic antibody. It binds to a unique, membrane proximal epitope of the CD137 receptor, leading to enhanced activation of T-Cells and NK Cells. CTX-471 has completed a Phase 1 dose escalation and cohort expansion study, where it was shown to be well-tolerated. The Phase 1b monotherapy study is fully enrolled and ongoing. In this study, CTX-471 has been evaluated as a monotherapy treatment in patients with advanced solid tumors who received at least one checkpoint inhibitor post progression. As of September 30, 2022, 4 partial responses (PRs) have been observed in the Phase 1b study and 3 of the 4 were confirmed by RECIST 1.1.
