Abstract

Insights

Antineoplastons show promise for treating high-grade brainstem gliomas, offering extended survival in a small patient group. This approach demonstrated good tolerance and potential for long-term outcomes in challenging brain tumor cases.

Area of Science:

  • Neuro-oncology
  • Clinical Trials
  • Cancer Therapeutics

Background:

  • Brainstem gliomas (HBSG) have a poor prognosis, with limited survival beyond 2 years.
  • Standard treatments like radiation and chemotherapy are often ineffective, especially for inoperable, high-grade tumors.
  • Effective treatment options for HBSG remain a significant clinical challenge.

Purpose of the Study:

  • To evaluate the efficacy and safety of antineoplastons in patients with high-grade brainstem gliomas.
  • To summarize outcomes from four Phase 2 clinical trials involving antineoplaston therapy.
  • To assess the impact of antineoplastons on overall survival and tumor response.

Main Methods:

  • 18 patients with high-grade brainstem gliomas (including glioblastomas and anaplastic HBSG) were evaluated.
  • Patients received escalating doses of antineoplaston A10 (A10I) and AS2-1 via intravenous injection.
  • Tumor response was assessed using MRI and PET scans, with a median treatment duration of 5 months.

Main Results:

  • Overall survival rates at 2 and 5 years were 39% and 22%, respectively.
  • Maximum survival exceeded 17 years for anaplastic astrocytoma and 5 years for glioblastoma.
  • Antineoplastons were well-tolerated, with only one case of reversible grade 4 toxicity (anemia).

Conclusions:

  • Antineoplastons demonstrated potential in achieving over 5-year survival for patients with recurrent diffuse intrinsic brainstem gliomas.
  • This treatment approach showed promise for challenging cases of glioblastomas and anaplastic astrocytomas.
  • Further investigation in larger cohorts may be warranted to confirm these findings.
