Correction: Gallus et al. Immunotherapy Approaches in Isocitrate-Dehydrogenase-Mutant Low-Grade Glioma. Cancers 2023, 15, 3726

Correction of Table 1

It has come to our attention that the previously published manuscript contained an outdated iteration of Table 1 [1].

Table 1. Clinical trials investigating immunotherapy for low-grade glioma.

The revised version incorporates the accurate table encompassing all pertinent studies with the appropriate NCT identifiers. Additionally, we have restructured the arrangement of studies, commencing with phase I and progressing to later-phase trials.
