Genenta Science announced on July 1, 2025, long-term follow-up observations from its glioblastoma multiforme (GBM) study, revealing emerging survival signals. A total of 38 patients were enrolled in the TEM-GBM study, with 25 receiving Temferon.

Two patients enrolled in the TEM-LT long-term follow-up study have survived three years from the time of their first surgery. One of these long-term survivors has not experienced disease progression following Temferon administration and has not required any second-line therapies, while the other showed initial signs of progression that subsequently stabilized without additional intervention.

As of the April data cutoff, the two-year survival rate in the GBM trial for unmethylated MGMT (uMGMT) patients remained consistent at 29%, with median overall survival holding steady at 17 months. These results continue to compare favorably to historical cohorts, where uMGMT patients receiving standard of care typically show a two-year survival rate of approximately 14% and a median overall survival of 13 to 15 months.
