Experimental therapy for deadly brain tumor stalls after single patient
NCT ID NCT02742883
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This phase 2 study tests two experimental drugs, atengenal and astugenal, in people with diffuse intrinsic pontine glioma (DIPG), a rare and aggressive brain tumor. The trial aimed to enroll up to 100 participants across five age and treatment groups, but only 1 person joined before the study was suspended. The goal was to see if the drugs could shrink tumors or extend survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Antineoplaston therapy (atengenal and astugenal)
- What this could lead to
- If it works, this could point toward a treatment for DIPG, a rare and aggressive brain tumor in children.
- What could go wrong
- The trial is very early (phase 2), has only 1 participant, and is currently suspended. Antineoplaston therapy is controversial and not widely accepted.

Inclusion Criteria: Five cohorts of patients with diffuse, intrinsic pontine glioma will be studied: 1. Patients age 3 months to \< 3 years; 2. Patients age 3-21 years with progressive disease (PD) following radiation therapy (RT) ± chemotherapy and/or other therapies; 3. Patients age 3-21 years with newly diagnosed DIPG who (or whose parents / guardians) have refused RT; 4. Patients age \> 21 years with PD following RT ± chemotherapy and/or other therapies; and 5. Patients age \> 21 years with newly diagnosed DIPG who have refused RT. Exclusion Criteria include: 1. Disseminated disease, multicentric tumors, or leptomeningeal disease; 2. Uncontrolled intercurrent illness; 3. A history of New York Heart Association Class II congestive heart failure or above; 4. Pregnancy.
