Real-time mirroring of therapy

Access through your institution Buy or subscribe Early assessment of treatment efficacy can be invaluable in cases of aggressive tumours, such as glioblastoma. Logun et al. generated

glioblastoma organoids (GBOs) from patients participating in a chimeric antigen receptor (CAR) T cell clinical trial to monitor the therapeutic response in real time. The authors obtained

tumour specimens from six patients with glioblastoma enrolled in a phase 1 CAR T cell clinical trial. Using a previously reported protocol, they developed GBOs from the specimens in 2–3

weeks, which they then co-cultured with patient-matched CAR T cells. These GBOs displayed tumour cytolysis. After 6 days of co-culturing, Logun et al. collected the GBOs and analysed them

for target antigen expression, which they found was reduced. Finally, they analysed CAR T cell–GBO co-culture media and found a continuous release of cytokines by the activated T cells,

which presented similar temporal dynamics with the in vivo kinetics of CAR T cell activation in patients. This is a preview of subscription content, access via your institution ACCESS
