Background about Glioblastoma and the new drug
Glioblastoma (GBM) has a poor prognosis, and patients with Epidermal Growth Factor Receptor (EGFR) amplification have an even worse prognosis.
Nimotuzumab is an EGFR monoclonal antibody thought to play a significant role in the treatment of GBM.
It is approved in India, China, and other countries for Head and Neck cancer.
The Epidermal Growth Factor Receptor (EGFR) is expressed to varying degrees in more than 40% of gliomas.
Activation of EGFR signaling causes uncontrolled tumor proliferation.
However, targeted therapy against EGFR amplification has emerged as one of the therapeutic options for gliomas.
In this article we will present a study that evaluates the clinical efficacy and safety of Nimotuzumab in Glioblastoma.
About the Study
A total of 56 newly diagnosed patients with EGFR-positive Glioblastoma were included.
The patients were divided into 2 groups:
Radiotherapy + Temodar + Nimotuzumab (39 patients) and Radiotherapy + Temodar (17 patients).
Patients in both groups underwent tumor resection surgery.
Time until disease progression (also called Progression-Free Survival, PFS), Survival and side effects were assessed.
Results
The median time until disease progression was 12.4 months and 8.2 months in the 2 groups, respectively
The median Survival was 27.3 months and 16.7 months, respectively
In patients with unmethylated MGMT, the median time until disease progression and Survival were significantly better in patients treated with Nimotuzumab:
The median time until disease progression was 19.3 vs 6.7 months
The median Survival was 20.2 vs 13.8 months
During the treatment period, no significant difference in toxicity was noted between the 2 groups.
Conclusion for Newly Diagnosed Glioblastoma Patients
This study suggests the efficacy of Nimotuzumab combined with radiotherapy and Temodar in patients with newly diagnosed EGFR-positive GBM, and specifically those with unmethylated MGMT promoter.
Nimotuzumab demonstrated good safety and tolerability.
