Abstract
BackgroundHu-rhEGF-rP64k/Mont is a biotechnology product for the treatment of advanced non-small cell lung cancer (NSCLC). The vaccine induces a neutralizing antibody-mediated immune response, against the normal circulating self-protein antigen epidermal growth factor (EGF), which prevents its binding to and activation of the EGF receptor, inhibiting the transduction of the signals that drive cancer cell proliferation, survival and spread. This phase I study aimed to evaluate the safety and the immunological response of Hu-rhEGF-rP64k vaccine in NSCLC patients.ResultsThe Hu-rhEGF-rP64k/Mont vaccine showed to be safe and well tolerated, with dizziness, injection-site reactions and tremors being the most commonly reported adverse event. No severe adverse events or death were related to the vaccination. Immune monitoring demonstrated the generation of anti-EGF antibody titers and as a consequence the patients exhibited a decrease in the EGF concentration. In 80% of the vaccinated patients stable disease was achieved.ConclusionHu-rhEGF-rP64k/Mont elicited a valuable immune response, with good safety profile assuring further clinical development of the vaccine in this population to further confirm the potential benefits on survival.Trial registrationChinese Clinical Trial Registry, ChiCTR-OID-17014048, date 2017/12/20 (retrospectively registered); Chinese Food and Drug Administration, CFDA 2009 L02105, date 2009/04/03; China Drug Trial, CTR20131039.
Highlights
Hu-Recombinant human epidermal growth factor (rhEGF)-rP64k/Mont is a biotechnology product for the treatment of advanced non-small cell lung cancer (NSCLC)
The platinum-based doublet chemotherapy has been the standard first-line treatment for non-selected patients with advanced NSCLC [4] and only produce modest survival improve compared with best supportive care
We report the results of a phase I clinical trial approved by the CFDA (2009/04/03, CFDA 2009 L02105), intended to demonstrate the safety, immunogenicity and efficacy of Hu-rhEGF-rP64k/Mont in patients with advanced NSCLC
Summary
Hu-rhEGF-rP64k/Mont is a biotechnology product for the treatment of advanced non-small cell lung cancer (NSCLC). The vaccine induces a neutralizing antibody-mediated immune response, against the normal circulating self-protein antigen epidermal growth factor (EGF), which prevents its binding to and activation of the EGF receptor, inhibiting the transduction of the signals that drive cancer cell proliferation, survival and spread. This phase I study aimed to evaluate the safety and the immunological response of Hu-rhEGF-rP64k vaccine in NSCLC patients. Lung cancer is the most common worldwide cancer, with 1.8 million new cases in 2012 (12.9% of the total). There is a great need for novel and more effective treatments for advanced NSCLC
