Modulation of Temozolomide Dose Differentially Affects T cell Response to Immune Checkpoint Inhibition

Newswise — SAN DIEGO (April 15, 2019) — Winner of the Preuss Research Award, Maryam Rahman, MD, FAANS, presented her research, Modulation of Temozolomide Dose Differentially Affects T cell Response to Immune Checkpoint Inhibition, during the 2019 American Association of Neurological Surgeons (AANS) Annual Scientific Meeting.

Temozolomide has been shown to have both synergistic and negative effects on immune response to different immunotherapy treatment platforms. Researchers aimed to determine the immune modulatory effects of temozolomide that would impact response to immune checkpoint inhibition in the treatment of experimental glioblastoma (GBM).

The study found that the peripheral and intratumoral immune microenvironments are distinctively affected by dose modulation of temozolomide impacting response to immune checkpoint inhibition in GBM. These results demonstrate the importance of thoughtfully modulating host immunity with chemotherapy, when combining with immunotherapy.
