The CAR T-cell neurotoxicity detection market is witnessing remarkable growth as the adoption of CAR T-cell therapies accelerates worldwide. These therapies, known for their promise in treating hematologic malignancies, have also highlighted the urgent need for early neurotoxicity detection due to risks like ICANS (immune effector cell-associated neurotoxicity syndrome). This article explores key trends, drivers, challenges, and opportunities shaping this market in 2025.
What is CAR T-Cell Neurotoxicity Detection?
CAR T-cell neurotoxicity detection involves tools, technologies, and services designed to identify and monitor neurotoxic side effects in patients receiving CAR T-cell therapy. Since neurotoxicity can range from mild symptoms like headaches to life-threatening complications, early detection through biomarkers, imaging, EEG, and AI-driven tools is critical for improving patient outcomes.
