The US Food and Drug Administration (FDA) granted orphan drug status to SurVaxM for patients with glioblastoma.1

SurVaxM is a vaccine that targets survivin, a cell-survival protein found in most cancers.

The FDA based its approval on interim data from an ongoing phase 2 study (ClinicalTrials.gov Identifier: NCT02455557). Researchers enrolled 50 patients to receive SurVaxM in 4 doses over the first 8 weeks of treatment with temozolomide, the standard treatment for glioblastoma. Patients will continue to receive the vaccine once every 12 weeks.

Results from the IT-09 phase 1 trial showed that 7 of 8 patients who had previously failed standard therapy for recurrent malignant glioma survived for more than a year, and 3 patients maintained stable disease after more than 12 months of follow up. The average life expectancy of patients with glioblastoma receiving standard therapy alone is 7 months.2

SurVaxM was well-tolerated and patients primarily experienced grade 1 adverse events (AEs), including erythema, fatigue, myalgia, lymphopenia, and leukopenia. The only grade 3 AE observed was seizure, which was determined not to be treatment-related.

SurVaxM is also being evaluated as a potential part of combination therapy for multiple myeloma.
