Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you need warfarin, phenytoin, or certain diabetes medications. It's best to discuss your current medications with the trial team.

What evidence supports the effectiveness of the drug LAM561 for treating pediatric brain tumors?

Research shows that 2-hydroxyoleic acid, a component of LAM561, has anti-cancer activity and can selectively kill glioma cancer cells, a type of brain tumor, without harming normal cells. It has been tested in a clinical trial for safety and preliminary effectiveness in patients with glioma, showing potential as a treatment.12345

What makes the drug LAM561 unique for treating pediatric brain tumors?

LAM561, also known as 2-hydroxyoleic acid, is unique because it selectively targets and kills cancerous glioma cells without harming normal cells, potentially offering a safer treatment option with fewer side effects compared to traditional therapies.34567

What is the purpose of this trial?

This trial tests a new drug called LAM561 in children with severe brain and other solid tumors. The goal is to find the safest and most effective dose by adjusting it and monitoring side effects. If the drug shows benefits without severe side effects, patients can continue using it even after the trial ends.

Eligibility Criteria

This trial is for children under 18 with advanced high-grade gliomas or other solid tumors that are getting worse, coming back, or not responding to standard treatments. They must be able to take oral medication and have good enough blood counts and organ function. Kids who can't walk due to paralysis but use a wheelchair can join too.

Inclusion Criteria

Recent mothers must agree not to breast feed while receiving medications on study.
My blood, kidney, and liver tests are within normal ranges.
My kidney function, measured by creatinine, is within the normal range for my age.

Exclusion Criteria

I have had a significant brain bleed detected by a scan in the last month.
I have high cholesterol that is hard to control or I am on medication to lower my cholesterol.
You have taken any experimental medication within a certain time frame before starting LAM561.

Treatment Details

Interventions

  • 2-OHOA
  • LAM561
Trial Overview The study tests LAM561 in two parts: first, finding the highest dose kids can handle without serious side effects (dose escalation), then giving more kids this dose to make sure it's safe (expanded safety cohort). It's an open-label trial, meaning everyone knows they're getting LAM561.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: Dose EscalationExperimental Treatment1 Intervention
The dose level corresponds to 80% of the maximum tolerated dose of LAM561 in adult patients when adjusted for body surface area. The escalation will be to the 100%, and 120% of the maximum tolerated dose of LAM561 in adult patients when adjusted for body surface area. Dose escalation decisions will be made by all active Investigators in collaboration with the Medical Monitor when at least three patients have completed the DLT observation period (Cycle 1) at each dose level. When the third patient at any given dose level has received 14 days of therapy, an "escalation teleconference" will be scheduled after that patient has completed the DLT observation period (Cycle 1). The decision to progress to the next dose level will be made on the basis of review of all significant LAM561-related toxicities.

Findings from Research

In a study of 329 glioma patients, those with high levels of SMS1 and low levels of SMS2 had a significantly better 5-year survival rate, suggesting that the expression levels of these enzymes could serve as important prognostic biomarkers.
The study found that SMS1 and SMS2 have opposing effects on glioblastoma cell growth and response to 2-Hydroxyoleic acid (2OHOA), with low basal SMS1 levels predicting a more favorable response to 2OHOA treatment.
The Opposing Contribution of SMS1 and SMS2 to Glioma Progression and Their Value in the Therapeutic Response to 2OHOA.Fernández-García, P., Rosselló, CA., Rodríguez-Lorca, R., et al.[2020]
In a Phase 1/2A trial involving 54 patients with glioma and other advanced solid tumors, the synthetic lipid 2-OHOA was found to be well-tolerated, with the most common side effects being mild nausea, vomiting, and diarrhea, establishing a recommended Phase-2 dose of 12,000 mg daily.
The treatment showed promising preliminary efficacy, particularly in patients with recurrent high-grade gliomas, where 24% experienced clinical benefits, including one patient with a remarkable response lasting over 2.5 years.

2-Hydroxyoleic acid (2OHOA) selectively induces endoplasmic reticulum (ER) stress and autophagy in human glioma cells (1321N1, SF-767, U118) without affecting normal MRC-5 cells, highlighting its potential as a targeted anti-cancer treatment.
The compound causes cell cycle arrest in glioma cells and upregulates key markers associated with ER stress and autophagy, suggesting a specific mechanism of action that contributes to its anti-cancer efficacy while minimizing toxicity to normal cells.
