Outcome Measures

Primary Outcomes (2)

  • Feasibility of fasting mimicking diet intervention

    Feasibility will be defined as the proportion of the patients who can finish the 3 cycles FMD without serious adverse events. The investigators define FMD as being a feasible intervention in NSCLC receiving checkpoint inhibitors if 70% of patients on study complete 3 cycles of FMD.

    Through study completion up to 2 years.

  • Compliance

    Compliance will be measured by analysis of daily food diaries at the end of each FMD cycle.

    Through study completion up to 2 years.

Secondary Outcomes (6)

  • Immune Mediated Toxicities

    Through study completion up to 2 years.

  • Overall response rate (ORR)

    Through study completion up to 2 years.

  • Disease control rate (DCR)

    Through study completion up to 2 years.

  • Progression Free Survival (PFS)

    Through study completion up to 2 years.

  • Functional Assessment of Cancer Therapy-Lung-(FACT-L)

    Through study completion up to 2 years.

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years at the time of informed consent
  • Ability to provide written informed consent and HIPAA authorization.
  • Eastern cooperative group (ECOG) performance status of 0 to 2
  • Newly diagnosed histologically or cytologically confirmed stage IV Non-Small Cell Lung Cancer (NSCLC). Patients with locally advanced NSCLC that are not candidates for definitive therapy but are candidates for trial are allowed per investigator discretion.
  • BMI 19 kg/m2
  • Patients should be enrolled prior to starting standard of care immunotherapy for the treatment of stage IV NSCLC. Patients should be on PD (L)1 inhibitor alone (i.e., with PD-L1 expression 50%) in the metastatic setting. The investigators will allow single agent pembrolizumab only as the checkpoint inhibitor.
  • Patients requiring palliative radiation or definitive radiation to an oligometastatic disease prior to the initiation of single agent checkpoint inhibitors are allowed once radiation has been completed and patients have recovered from toxicities.

You may not qualify if:

  • Self-reported weight loss of \> 10% in the 6 weeks prior to study entry
  • History of symptomatic hypoglycemia or uncontrolled diabetes
  • Prior therapies with inhibitors of insulin growth factor I(IGF-1) such as Linsitinib or Picropodophyllin
  • Concurrent use of somatostatin
  • Concurrent use of immunosuppressive medications including sirolimus, tacrolimus, mycophenolate mofetil, azathioprine, prednisone, dexamethasone, or cyclosporine
  • Significant food allergies which would make the subject unable to consume the food provided.
  • History or current evidence of any uncontrolled medical or psychiatric condition, therapy that may confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the participating subject as deemed by the treating investigator.
  • Pregnant or lactating females are not eligible.

Intervention Model
CROSSOVER
Model Details: Multi-center, open label, phase 2, randomized (partial crossover design) study evaluating the feasibility of FMD in stage IV NSCLC patients receiving single agent checkpoint inhibitors. Participants will be randomized 1:1 in blocks of 3. There is no blinding or stratification. Patients with high PDL1 NSCLC will be randomized to two arms: (Arm 1) 3 cycles of RD+PD1 inhibitors followed by 3 cycles of FMD+PD1 inhibitors or (Arm 2) 3 cycles of FMD+PD1 inhibitors.
