The study investigated the impact of intratumoral hypoxia on chimeric antigen receptor T-cell (CAR-T) therapy in non-Hodgkin's Lymphoma (NHL) using a PET imaging technique called [F]FAZA.
Of the 16 patients scanned, a minimal number showed significant hypoxia, with only one patient meeting the threshold for intratumoral hypoxia and experiencing early treatment failure.
Due to the low incidence of positive scans indicating hypoxia, the study was halted for being unlikely to yield meaningful results, and future research may focus on a more selective patient group.
