The U.S. market for PEGylated drugs has experienced rapid growth, surpassing USD 6 billion in 2017 and projected to exceed USD 8 billion by 2024, according to Global Market Insights. These therapies, which use polyethylene glycol (PEG) to enhance drug stability and bioavailability, have become increasingly vital in oncology, immunology, and rare disease treatment. However, as their use expands, so too does concern over safety. While it is well-established that some PEGylated drugs can trigger acute hypersensitivity and anaphylaxis, emerging evidence now points to PEG itself—not just the drug component—as a direct cause of severe allergic reactions in a sensitized subset of individuals.
To address this critical safety gap, Leading Life Technologies (LLT) has developed a powerful solution based on its patented FocalTuning™ immunoassay platform (US10,914,731B2; US11,835,517B2; ZL202080015982.5). This technology enables highly sensitive and specific detection of anti-PEG IgE, a key biomarker of PEG-induced anaphylaxis. By delivering accurate results even at picogram levels, FocalTuning helps researchers, pharmaceutical developers, and clinicians detect PEG sensitization with unparalleled clarity—especially in cases where traditional skin tests or ELISAs fall short. This allows for better safety profiling of PEGylated products across preclinical development, clinical trials, and post-market surveillance.
LLT’s PEG IgE detection products and services are designed to support both drug developers and healthcare providers in making informed, patient-centered decisions. By identifying individuals at risk for PEG-related hypersensitivity early in the treatment process, FocalTuning empowers pharmaceutical innovation without compromising safety. As the therapeutic landscape continues to evolve, LLT remains committed to bridging the gap between cutting-edge drug development and precision diagnostics—helping ensure that PEGylated therapies are not only effective, but also safer for every patient.
