Adegramotide (DSP-7888) is an experimental drug intended for treatment of various hematologic malignancies and solid tumors, including glioblastoma multiforme.^[1] It is a peptide vaccine and has finished phase I clinical trials and phase II clinical trials.^{[2] [3]}

As of, phase III clinical research has been cancelled due to low efficacy markers during interim review of study data for Ombipepimut-S Emulsion (DSP-7888) in combination with Bevacizumab.^{[4] [5]}

The phase III trials for DSP-7888 with checkpoint inhibitors for platinum-resistant ovarian cancer, as of, is still continuing as planned.^[6]
