What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how different dietary changes affect butyrate levels in stool for people with smoldering multiple myeloma. Participants will try one of four options: a whole food, plant-based diet, omega-3 supplements, curcumin supplements, or probiotics. This study suits those diagnosed with smoldering multiple myeloma who are interested in plant-based cooking and can manage study tasks like meal prep and surveys, with or without help. As an unphased trial, it offers a unique opportunity to contribute to scientific understanding and potentially improve dietary recommendations for smoldering multiple myeloma.

Will I have to stop taking my current medications?

The trial requires participants to stop taking certain supplements like curcumin, probiotics, and omega-3 for 2 weeks before joining. However, it does not specify stopping other medications, so you may not need to stop your current medications unless they fall under specific exclusions like prescription weight loss drugs or therapeutic myeloma drugs.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that each treatment in this trial has different safety levels, but they are generally well-tolerated.

For the whole food, plant-based diet (WFPBD), studies have linked it with health benefits and a lower risk of multiple myeloma, with no major safety concerns reported. People on this diet often experience positive health effects.

Omega-3 supplements, which include EPA and DHA, are considered safe and have a strong safety record. These fatty acids can target cancer cells without harming normal cells, making them a promising option with few side effects.

Curcumin, a substance found in turmeric, is regarded as safe and well-tolerated. The FDA has approved it for use in some cases, and studies have shown it has low toxicity.

Probiotics, which help maintain gut health, are usually safe for most people. However, limited information exists specifically for multiple myeloma patients. Some studies suggest caution due to possible risks like infections, especially in individuals with weakened immune systems.

Overall, these treatments are generally safe, but individual responses can vary. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for multiple myeloma because they offer unique, natural approaches. Unlike conventional treatments, which often involve chemotherapy or stem cell transplants, these options explore dietary and supplement-based interventions. The whole food, plant-based diet (WFPBD) focuses on minimally processed foods like legumes, fruits, and vegetables, aiming to harness the natural benefits of plant nutrients. Omega-3 supplements, curcumin, and probiotics are being studied for their potential anti-inflammatory and immune-supportive properties. These treatments are intriguing because they might provide complementary benefits with fewer side effects, offering a novel angle in managing multiple myeloma.

What evidence suggests that this trial's treatments could be effective for smoldering multiple myeloma?

Research suggests that a whole food, plant-based diet (WFPBD), which participants in this trial may receive, might slow the progression of smoldering multiple myeloma (SMM) by increasing fiber intake. Studies have shown that a high-fiber diet can benefit people at risk of developing multiple myeloma. Another treatment option in this trial is Omega-3 fatty acids, which can be taken as supplements and have been shown to help kill multiple myeloma cells and may enhance the effects of other treatments. Curcumin, a natural compound in turmeric, is also under study in this trial and might slow the growth of multiple myeloma cells by blocking certain pathways that promote tumor growth. Probiotics, another treatment arm in this trial, can support a healthy gut, which is linked to better outcomes in multiple myeloma, by producing butyrate, a compound that can kill cancer cells. Each of these approaches shows promise in targeting different aspects of multiple myeloma. ^{1 6 7 8 9}
