What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests if not eating for a certain number of hours each night can help overweight and obese people with certain pre-cancerous conditions avoid developing blood cancer. The study involves a small group of people who will either follow the fasting plan or receive healthy living tips. Not eating for a set period each night is a new approach for weight loss that may have additional health benefits.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

How is the Prolonged Fasting Intervention treatment different from other treatments for multiple myeloma?

The Prolonged Fasting Intervention is unique because it uses fasting to potentially protect normal cells while targeting cancer cells, unlike traditional treatments that often involve drugs or chemotherapy. This approach is still being researched, but it may help reduce the side effects of other cancer treatments and improve their effectiveness. ^{1 2 3 4 5}

What data supports the effectiveness of the fasting treatment for multiple myeloma prevention?

Research suggests that fasting can enhance the effectiveness of cancer treatments by reducing harmful side effects and improving treatment outcomes. Studies have shown that fasting or fasting-mimicking diets can lower levels of certain growth factors and hormones that cancer cells need to grow, potentially making treatments more effective. ^{2 3 5 6 7}

Are You a Good Fit for This Trial?

This trial is for overweight or obese adults with precursor blood cancers like MGUS, SMM, or SWM who fast less than 14 hours at night. Participants must be comfortable using a cell phone to send texts and have no active cancer treatments, diabetes without doctor's consent, night shift work, eating disorders affecting nighttime eating, or use of weight loss meds.

Inclusion Criteria

My diagnosis is MGUS, Smoldering MM, or Smoldering WM, confirmed by medical records.

Ability to understand and the willingness to sign a written informed consent document

You have a cell phone and can send and receive text messages easily.

Exclusion Criteria

I don't have conditions that would prevent me from fasting at night or participating fully in the trial.

I have been diagnosed with multiple myeloma or Waldenström's macroglobulinemia.

I am currently being treated for another type of cancer.

What Are the Treatments Tested in This Trial?

Interventions

• EDUCATION CONTROL
• Prolonged Fasting Intervention

Trial Overview The study tests if not eating for extended periods at night (PROFAST) can help prevent blood cancer in individuals at risk. It randomly assigns participants to either the PROFAST group that practices prolonged fasting nightly for four months or a control group that follows a healthy lifestyle without specific fasting instructions.

How Is the Trial Designed?

Group I: PROLONGED FASTING INTERVENTION Experimental Treatment 1 Intervention

The prolonged nightly fasting (PROFAST) intervention involves gradually working up to a 14-hour fast during the nighttime hours. Participants will be supported by means of calls with a health coach during the first 4 weeks of the study. Participants will also be asked to use a text messaging platform to record their first and last meal of the day, and will receive personalized feedback based on the meal times they record via the text messaging system. The text messaging system will be used throughout the duration of the study.

Group II: EDUCATION CONTROL Active Control 1 Intervention

For participants randomized to the control group, an introductory session with a health coach and educational information will be provided. Participants will also receive one email and one text message per week with tips on healthy living during the 4 months of the study

Published Research Related to This Trial

Periodic fasting enhances the effectiveness of endocrine treatments for hormone receptor-positive breast cancer by increasing their anti-cancer activity.

Fasting may help delay the development of resistance to these treatments by lowering levels of blood leptin, insulin, and insulin-like growth factor 1 (IGF1), suggesting a potential new strategy for improving breast cancer therapy.

Enhancing endocrine therapy activity via fasting cycles: biological rationale and clinical feasibility. Caffa, I., Nencioni, A.[2021]

Fasting may serve as a promising anticancer strategy by enhancing the survival of normal cells while potentially killing cancer cells, supported by nonclinical evidence showing it can reduce chemotherapy toxicity and improve its effectiveness.

Current clinical research on fasting as an adjunct to chemotherapy is encouraging but still in early stages, highlighting the need for personalized approaches and further studies to establish safety and efficacy through large randomized trials.

Peri-chemotherapy fasting is considered safe for well-nourished cancer patients undergoing short-term chemotherapy, with good patient compliance and only mild weight loss reported.

While some studies suggest potential benefits, such as improved tumor response in breast cancer, claims of significant oncological advantages from fasting during chemotherapy are currently premature and not well-supported by clinical data.

Fasting or a fasting-mimicking diet (FMD) can slow down tumor growth but does not enhance the sensitivity of colorectal cancer (CRC) cells to chemotherapy drugs like 5-fluorouracil and oxaliplatin, indicating a complex relationship between fasting and cancer treatment.

The study identified that fasting induces CRC cells to enter a slow-cycling state, which may lead to the development of drug-tolerant persister cells that contribute to cancer relapse; however, combining fasting with ferroptosis inducers could enhance tumor inhibition and target these resistant cells.

The 5-day Fasting-Mimicking Diet (FMD) was found to be safe and feasible for cancer patients undergoing treatment, with only mild side effects reported during the study involving 90 participants.

FMD led to beneficial changes in body composition, including reduced fat mass and stable weight, while also decreasing levels of insulin and growth factors like IGF1 and leptin, suggesting potential metabolic benefits alongside cancer treatment.

In a phase II study involving 129 patients with HER2-negative breast cancer, a fasting mimicking diet (FMD) improved patients' perceptions of chemotherapy side effects and overall quality of life compared to a regular diet.

Patients adhering to the FMD reported better emotional, physical, and social functioning, along with lower levels of fatigue, nausea, and insomnia, suggesting that FMD may enhance the supportive care during neoadjuvant chemotherapy.

A study of 139 breast cancer patients during Ramadan found that fasting did not negatively affect adherence to oral hormonal therapies, with adherence rates of 94.2% during Ramadan and 95.7% in the month prior.

Factors such as previous non-adherence and shorter duration of hormonal therapy were significant predictors of non-adherence during Ramadan, while fasting and other demographic factors did not influence treatment compliance.
