Summary

This phase I trial studies the side effects of short-term fasting in patients with skin malignancy that has spread to other places in the body (advanced or metastatic) treated with a PD-L1 or PD-1 inhibitor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, nivolumab, cemiplimab, avelumab, atezolizumab, or durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Undergoing short-term fasting prior to treatment with one of these PD-L1 or PD-1 inhibitors may potentially reduce the side effects of immunotherapy or even improve the effectiveness of immunotherapy in patients with skin malignancy.

Description

PRIMARY OBJECTIVES:

I. To evaluate the safety and feasibility of short term fasting in combination with PD-1 inhibition therapy for patients with advanced malignancy.

Ia. To estimate the percentage of patients who adhere completely to short term fasting (STF) in combination with PD-1 inhibition therapy for 3 cycles.

Ib. To estimate the percentage of patients who develop unacceptable fasting-related toxicity.

SECONDARY OBJECTIVES:

I. To measure how many patients can adhere with STF for at least 2 cycles in combination with PD-1 inhibition.

Ia. To estimate the percentage of patients who adhere to STF in combination with PD-1 inhibition therapy for at least 2 cycles, or a total of at least 6 out of 9 days.

II. To measure all grades of fasting-related toxicity. IIa. To estimate the percentage of patients who develop any grades of fasting-related toxicity, including acceptable fasting-related toxicity.

EXPLORATORY OBJECTIVES:

I. The efficacy of combining STF with PD-1/PD-L1 inhibition will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1 response rate, as measured at the time of tumor assessment after 3 cycles of treatment.

II. The immune-related toxicity of combining STF with PD-1/PD-L1 inhibition will be recorded at the start of each cycle, and graded per Common Terminology Criteria for Adverse Events (CTCAE) v 4.0.

III. Quality of life during STF combined with PD-1/PD-L1 inhibition will be recorded using the Functional Assessment of Cancer Therapy - General (FACT-G) version 4, questionnaire tool.

IV. Fasting-related biomarkers to measure the impact of STF during PD-1/PD-L1 inhibition include measurement of serum insulin/IGF-1, PI3K/AKT/mTOR signaling, MAPK pathway signaling, and markers of oxidative stress.

V. Immune biomarkers will be analyzed using immunohistochemistry and ribonucleic acid (RNA) expression studies.

OUTLINE

Patients undergo STF for 47-48 hours prior to immunotherapy and for 24 hours after immunotherapy with standard of care pembrolizumab given intravenously (IV) over 30 minutes, nivolumab IV over 30 minutes, cemiplimab IV over 30 minutes, avelumab IV over 60 minutes, atezolizumab IV over 60 minutes, or durvalumab IV over 60 minutes on day 3. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up in 3-6 weeks.

criteria. Patients with other solid tumors may be eligible if they have a
Eastern Cooperative Oncology Group (ECOG) performance status 0-1
cutaneous metastasis amenable to biopsy (with approval of PI only)
Absolute neutrophil count >= 1,000/mcL
Absolute lymphocyte count >= 500/mcL
Hemoglobin >= 8.0 g/dL
Platelets >= 75,000/mcl
Total bilirubin =< 1.5 x institutional upper limit of normal
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional upper limit of normal
Creatinine =< 1.8 mg/dl or calculated creatinine clearance > 40 ml/min
Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria
Has not undergone a hysterectomy or bilateral oophorectomy; or
Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
Body mass index (BMI) >= 18.5
Ability to understand and the willingness to sign a written informed consent and comply with short-term fasting during study and other study-related procedures

Exclusion Criteria

Patients with history of diabetes mellitus are not eligible for this study
Note: patients with pre-diabetes or a history of diabetes which subsequently resolves, who are not taking metformin or any other diabetes medications are eligible
Subjects on medications that may not be safely stopped during the fasting portion of the study, or which may not be safely consumed without food
Patients with recent significant or unexplained weight loss that the investigator
Prior history of syncope with caloric restriction in the past or other medical comorbidity which would make fasting potentially dangerous
Prior treatment with any agent that blocks the PD-1 or PD-L1 pathway
feels may pose an unacceptable risk for enrollment should be excluded
Prior treatment with other immune modulating agents within fewer than 4 weeks, prior to the first dose of PD-1/PD-L1 inhibition. Examples of immune modulating agents include blockers of CTLA-4, 4-1BB, OX-40, therapeutic vaccines, or cytokine therapies
(Candidates who are overweight and have intentionally lost weight via diet or
exercise should be excluded, for instance)
Patients must not be receiving other concomitant biologic therapy, hormonal therapy, chemotherapy, other anti-cancer therapy or any other investigational agents while on this protocol
Radiation therapy, non-cytotoxic agents or investigational agents in the 4 weeks prior to the first dose of PD-1/PD-L1 inhibition
Immunosuppressive systemic corticosteroids equivalent to prednisone 10 mg or greater in the 14 days prior to the first dose of PD-1/PD-L1 inhibition
Any major surgery within 14 days prior to the first dose of PD-1/PD-L1 inhibition. Patients must have recovered from any major complications before registration
Active autoimmune disease requiring systemic treatment in the past 2 years (i.e. use of disease modifying agents or immunosuppressive drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc) is not considered a form of systemic treatment
Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
History of allergic reactions attributed to compounds of similar chemical or biologic composition to PD-1 or PD-L1 inhibitor
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Positive pregnancy test, active pregnancy or nursing/breast-feeding, due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants
History of solid organ or bone marrow transplantation
