Pilot Study of Intermittent Fasting With Immune Checkpoint Inhibitors
Feasibility and Immunometabolic Effects of Intermittent Fasting During Immune Checkpoint Inhibitor Therapy: A Randomized Pilot Study in Advanced Solid Tumors
This single-site, randomized pilot study will evaluate whether intermittent fasting is feasible and safe for patients with advanced solid tumors who are starting immune checkpoint inhibitor (ICI) therapy at the WVU Cancer Institute. Participants will be assigned to 1 of 3 groups: usual care with no fasting, alternate-day fasting (ADF), or time-restricted eating (TRE).
Participants in the ADF group will follow cycles of 12 hours of eating followed by 36 hours of fasting every other day. Participants in the TRE group will eat all daily calories within an 8-hour window each day. The fasting intervention will begin within 1 week of starting ICI treatment and continue for approximately 20-24 weeks during 8 cycles of therapy.
The study will evaluate adherence to the fasting regimens and compare side effects between groups. Researchers will also study changes in metabolic and immune biomarkers, fatigue, sleep, and quality of life. Participants will be followed for 30 days after completion of the intervention to monitor safety and tolerability.

参加者グループ / アーム |
介入・治療 |
|---|---|
|
介入なし：Usual Care, No Fasting
Participants will receive standard nutrition education materials per institutional practice.
No fasting regimen will be prescribed during immune checkpoint inhibitor (ICI) therapy.
|
|
|
実験的：Alternate-Day Fasting (ADF)
Participants will follow a repeating cycle of approximately 12 hours of eating followed by 36 hours of fasting every other day during ICI therapy.
During fasting periods, participants may consume plain coffee, sugar-free tea, sugar-free herbal tea, sugar-free chewing gum, and 1-2 cups per day of clear vegetable or meat broth (up to 500 kcal/day).
The fasting intervention will begin within 1 week of ICI initiation and continue for 8 cycles of therapy (approximately 20-24 weeks).

Participants will follow an alternate-day fasting regimen during ICI therapy consisting of approximately 12 hours of eating followed by 36 hours of fasting every other day.
|
|
実験的：Time-Restricted Eating (TRE)
Participants will consume all daily calories within an 8-hour eating window each day during ICI therapy, typically between 10:00 AM and 6:00 PM, with flexibility to shift the window by 1 hour earlier or later.
Outside the eating window, participants may consume plain coffee, tea, herbal tea, sugar-free chewing gum, and 1-2 cups per day of clear broth.
The fasting intervention will begin within 1 week of ICI initiation and continue for 8 cycles of therapy (approximately 20-24 weeks).

Adherence to Assigned Intermittent Fasting Regimen
時間枠：Up to approximately 24 weeks (8 treatment cycles)
|
Adherence will be assessed using participant-completed fasting diaries. For the time-restricted eating (TRE) arm, adherence is defined as meeting the assigned fasting window on ≥5 days per week. For the alternate-day fasting (ADF) arm, adherence is defined as meeting fasting-day criteria on ≥5 days within each 14-day period. Adherence will be summarized as the proportion of participants who meet the assigned regimen-specific adherence criteria during the study period. |
Up to approximately 24 weeks (8 treatment cycles)

Incidence of Adverse Events
時間枠：Up to approximately 24 weeks (8 treatment cycles) plus 30-day safety follow-up
|
Adverse events (AEs) and immune-related AEs (irAE) will be summarized and compared descriptively between study arms.
Events will be graded according to CTCAE.
The proportion of participants experiencing irAEs, including grade ≥3 irAEs, will be summarized by treatment group.
