Tohoku Univ. Technology ：Predictive Markers for the Efficacy of Immune Checkpoint Inhibitors：T25-021
Discovery of a Correlation Between Blood Levels of a Compound and Post-ICI Survival Time
Immune checkpoint inhibitors (ICIs) offer lasting treatment efficacy and improved survival for cancer patients, but positive responses are limited to select individuals and treatment costs are high, highlighting the need to predict benefit before therapy. Current predictive methods like PD-L1 testing mainly measure local tumor tissue expression and fail to fully assess systemic immunity. Researchers examined blood lysophosphatidylcholine (LPC) levels and clinical outcomes after ICI therapy in squamous cell carcinoma patients. They found that those with higher LPC had significantly prolonged survival post-ICI compared to those with lower levels. Because LPC is measurable in blood samples, it reflects systemic immune status and reduces patient burden by eliminating biopsies. This finding supports developing new clinical tests for predicting ICI effectiveness.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
