The Science Behind ARKA-101

Understanding our lipid-based approach

Why lipids matter in health

Lipids, including fatty acids, are essential building blocks of our cells. They make up cell membranes, serve as energy sources, and play important roles in cell signaling. Different types of fatty acids can have different effects on cellular processes. Gamma-linolenic acid (GLA) is an omega-6 fatty acid that has been studied for various biological effects.

Why tumor cells may be vulnerable

Research has shown that cancer cells often have altered lipid metabolism compared to normal cells. These differences may make tumor cells more susceptible to certain lipid-based interventions. Studies have observed that glioma cells may be particularly affected by GLA, potentially due to differences in how they process and respond to fatty acids.

Why local delivery is being explored

The brain is protected by the blood-brain barrier, which limits many treatments from reaching brain tumors at effective concentrations. Local delivery—administering treatment directly to the tumor site—is being explored as a way to achieve meaningful concentrations at the target while minimizing systemic exposure. This approach has been used with other treatments and is being investigated for GLA delivery.
