About this study
Official title: Short-Term Fasting Prior to Standard Checkpoint Blockade Using PD-1/PD-L1 Inhibition: A Pilot Safety and Feasibility Study
This 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.
Read the detailed description
PRIMARY OBJECTIVES:
- 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:
- 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:
- 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.
- 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of patients completely adhering to 3 cycles of short term fasting (STF) (9 days of fasting)
Complete adherence will be defined as patients who adhere to STF (consumption of less than 200 kilocalorie [kCal] per 24 hours) in combination with PD-1/PD-L1 inhibition therapy for all 3 cycles of therapy (total of 9 days of fasting). Will be described with descriptive statistics.
Measured: Up to 3 cycles (each cycle is 21 days)
Percentage of patients who develop unacceptable fasting-related toxicity
Will be graded per Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The safety benchmark will be set at 0 subjects in the total cohort experiencing fasting-related toxicity, i.e., if even 1 patient experiences unacceptable fasting-related toxicity, the study will be discontinued.
Measured: At the start of each cycle (prior to immunotherapy infusion), up to 3 cycles (each cycle is 21 days)
Secondary outcomes (2)
Percentage of patients who can partially adhere to 3 cycles of STF (9 days of fasting)
Partial adherence will be defined as patients who adhere to STF (consumption of less than 200 kCal per 24 hours) in combination with PD-1/PD-L1 inhibition therapy for at least 2 cycles of therapy, or at least 6 out of total 9 days of fasting. Will be described with descriptive statistics.
Measured: Up to 3 cycles (each cycle is 21 days)
Incidence of acceptable fasting related toxicity
Fasting-related toxicity is to be recorded at the start of each cycle (prior to immunotherapy infusion), and graded per CTCAE v 4.0. Incidence of adverse events related to fasting, including acceptable fasting-related toxicity, will be evaluated.
Measured: At the start of each cycle (prior to immunotherapy infusion), up to 3 cycles (each cycle is 21 days)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Atezolizumab, Avelumab and Cemiplimab in people with Advanced Malignant Skin Neoplasm and Metastatic Malignant Skin Neoplasm, run by University of Southern California at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 32 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of patients completely adhering to 3 cycles of short term fasting (STF) (9 days of fasting) (time frame: Up to 3 cycles (each cycle is 21 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2026.
