Methionine-Reduced Diet for Cancer

This trial explores how a diet low in methionine, an amino acid found in many foods, affects people with solid tumors who are also receiving standard cancer treatments. The goal is to determine if reducing methionine can alter certain blood levels and potentially aid treatment. Individuals with metastatic solid tumors, meaning the cancer has spread, or tumors that cannot be removed, might be suitable candidates. Participants should be willing to follow a special diet and continue their prescribed cancer therapy. As an Early Phase 1 trial, this research aims to understand how the treatment works in people, offering participants a chance to contribute to groundbreaking cancer research.

The trial information does not specify if you need to stop taking your current medications. It seems you can continue your standard cancer therapy, but it's best to discuss your specific medications with the trial team.

Research has shown that a diet low in methionine is generally safe and well-tolerated. Previous studies suggest that this diet can be combined with treatments like chemotherapy without causing major side effects. In one study, participants managed the diet well alongside a cancer drug, with an average survival time of 4.6 months. Importantly, the diet usually did not lead to unexpected severe toxic effects.

Unlike the standard cancer treatments, which often involve chemotherapy, radiation, or surgery, a methionine-reduced diet aims to tackle cancer by limiting the amino acid methionine found in many proteins. This unique approach is based on the idea that cancer cells rely heavily on methionine to grow and multiply. By reducing methionine intake, researchers hope to starve the cancer cells while sparing normal cells, potentially leading to fewer side effects. Researchers are excited about this treatment because it represents a novel, non-toxic strategy that could work alongside existing therapies to improve patient outcomes.

Research suggests that a diet low in methionine might help treat cancer. Methionine, an important building block, is found in many foods. Studies have shown that reducing methionine can slow cancer cell growth. Some research also indicates that this diet might enhance the effectiveness of chemotherapy and radiation. For instance, when mice followed a low-methionine diet, these treatments more effectively shrank tumors. Another study found that this diet could decrease tumor size and reduce cancer spread to the lungs. While most evidence comes from animal studies, these findings suggest that reducing methionine could benefit cancer patients. Participants in this trial will follow a methionine-reduced diet to evaluate its effects on cancer treatment.¹²³⁴⁶
