About this study

Official title: Fasting-Mimicking Diet Combined With Toripalimab Plus Axitinib for Metastatic or Unresectable Renal Cell Carcinoma: A Single-Arm, Open-Label, Single-Center Clinical Trial

This study is testing whether adding a 5-day fasting-mimicking diet (FMD) can help people with advanced kidney cancer when given together with standard first-line cancer medicines.

Read the detailed description

FMD is a plant-based diet that is low in protein and carbohydrates but higher in healthy fats. For 3 to 7 days at a time, people eat less than 1,100 calories per day. The goal is to copy some of the helpful effects that complete fasting has on slowing cancer cell growth, while avoiding the problems of full fasting such as extreme hunger or malnutrition.

In laboratory studies with mice, FMD has been shown to work like water-only fasting to fight tumors. When combined with chemotherapy, immunotherapy, or targeted therapy, it can slow tumor growth and help the mice live longer.

For advanced kidney cancer, the usual first treatment is a combination of targeted therapy plus immunotherapy. Researchers want to find out if adding FMD to this standard treatment can help patients live longer and feel better.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Fasting mimicking dietDietary supplement

    The fasting-mimicking diet (FMD) consists of a 5-day regimen: day 1 supplies 600 kcal (10-17% protein, 30-35% fat, 51-59% carbohydrate), days 2-5 are identical in formulation and provide 300 kcal (11-17% protein, 73-77% fat, 8-12% carbohydrate).

  • ToripalimabDrug

    Also called Tuoyi

    Toripalimab 240 mg IV every 3 weeks (240 mg Q3W) on a 21-day cycle

  • AxitinibDrug

    Also called Inlyta

    Axitinib 5 mg orally twice daily (BID).

Study groupRoleWhat they receive
Fasting-Mimicking Diet (FMD) Combined with Toripalimab Plus AxitinibExperimentalThe fasting-mimicking diet (FMD) is a plant-based dietary regimen that is low in protein and carbohydrates but relatively high in fats. It strictly limits daily caloric intake to less than 1,100 kcal for 3 to 7 consecutive days. The goal of FMD is to replicate the inhibitory effects of complete fasting on tumor cell growth and invasion, while avoiding the side effects associated with full fasting, such as malnutrition and other adverse events.
Receives: Dietary Supplement: Fasting mimicking diet; Drug: Toripalimab; Drug: Axitinib

Questions about this trial

What is this clinical trial studying?

A study testing Fasting mimicking diet, Toripalimab and Axitinib in people with Carcinoma, Renal Cell and Metastatic Renal Cell Carcinoma, run by Qilu Hospital of Shandong University at 1 site in China.

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 14 inclusion and 20 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: opening soon, as of the sponsor's last update on 30 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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.

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?

Contact YiPing Wang (+8613963647619, wypsduedu@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and Severity of Adverse Events (time frame: From the first administration of fasting-mimicking diet (FMD) combined with anticancer treatment until 40 days after the completion of the last FMD cycle combined with anticancer treatment.). 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 30 Mar 2026.
