Brief Summary:
The purpose of this study is to assess objective response rate (partial and complete response) of Nivolumab and Ipilimumab concomitant to a special diet (ketogenic diet, continuous or discontinuous) or standard diet with or without BHB according to RECIST v1.1 at 8 weeks.

Condition or disease Intervention/treatment Phase
Metastatic Renal Cell Carcinoma Dietary Supplement: Continuous ketogenic diet Dietary Supplement: Discontinuous ketogenic diet Dietary Supplement: beta-hydroxybutyrate (BHB) supplementation Not Applicable

Detailed Description:

After being informed about the study and potential risks, all patients giving informed consent will undergo a 10 days screening period to determine eligibility for study entry. At week1day1, patients who meet the eligibility requirements will be sequentially enrolled in a 1:1:1:1 ratio to :

  • Arm A : continuous ketogenic diet for 3 months
  • Arm B : discontinuous ketogenic diet (15 days on, 15 days off) for 3 months
  • Arm C : oral liquid ketone supplement BHB monoester, 15 days-on 15 days off during 3 months.
  • Arm D : standard diet (without any diet restrictions). and follow up as in arms A, B, C.

All patients will receive Nivolumab plus Ipilimumab according to practical routine.

Official Title: A Pilot Study Evaluating a Ketogenic Diet Concomitant to Nivolumab and Ipilimumab in Patients With Metastatic Renal Cell Carcinoma
Estimated Study Start Date : November 8, 2021
Estimated Primary Completion Date : November 8, 2024
Estimated Study Completion Date : November 8, 2024


Arm Intervention/treatment
Experimental: A
patients will be asked to follow in a continuous way a very low-carbohydrate, high-fat diets, which strictly limit carbohydrate consumption (less than 40g / day) and allow unlimited consumption of high-fat foods, such as pork belly, butter, coconuts oils, fat meat, eggs and cheese, etc… (cf appendix A). Patients will be provided with 2 meals (lunch and dinner), every meal with 2 dishes (first course and main course) and bread for every day for 3 months (ELIOR partnership).
Dietary Supplement: Continuous ketogenic diet
ARM A : continuous ketogenic diet

Experimental: B
patients will be asked to follow in a discontinuous way (15 days on, 15 days off) a very low-carbohydrate, high-fat diets, which strictly limit carbohydrate consumption (less than 40g / day) and allow unlimited consumption of high-fat foods, such as pork belly, butter, coconuts oils, fat meat, eggs and cheese…etc (cf appendix A). Patients will be provided with 2 meals (lunch and dinner), every meal with 2 dishes (first course and main course) and bread for every day for the ketogenic diet period for 3 months (ELIOR partnership).
Dietary Supplement: Discontinuous ketogenic diet
ARM B : discontinuous ketogenic diet

Experimental: C
patients will receive oral liquid ketone supplement BHB monoester, 2 tablespoons three times per day (depending on patient weight: at least 1g/kg weight body/day) 15 days-on 15 days off during 3 months. We would recommend taking it at least 30 to 60 min before meal times and they will receive standard diet (without any diet restrictions).
Dietary Supplement: beta-hydroxybutyrate (BHB) supplementation
ARM C : BHB supplementation

No Intervention: D
patients will receive standard diet (without any diet restrictions) and be followed up as in arms A, B, C.



Primary Outcome Measures :
  1. Objective response rate [ Time Frame: at 8 weeks after diet initiation. ]
    Preliminary activity will be assessed by measuring objective response rate (ORR) (partial/complete response) of Nivolumab plus Ipilimumab concomitant to a special diet (KD continuous or discontinuous) or standard diet (SD) with or without (BHB) according to RECIST v1.1 at 8 weeks.


Secondary Outcome Measures :
  1. Safety of Nivolumab plus Ipilimumab concomitant to a special diet [ Time Frame: Events reported from the first day of diet and up to and including 100 days following the last day of diet could be included in estimating this incidence rate. ]
    the safety of Nivolumab plus Ipilimumab concomitant to a special diet (ketogenic diet, continuous or discontinuous) or standard diet (SD) with or without BHB will be measured by the rate of all and grade 3-4 adverse events (AEs) according to CTCAEv4, and compare the rate to historical datas.

  2. Assessment of weight [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    Assessment of weight in kilograms by baseline test and follow up in order to evaluate the impact of the diet concomitant to immunotherapy on nutritional status, muscle mass, and sarcopenia.

  3. Assessment of albuminemia [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    Assessment of albuminemia in g/L in order to evaluate the impact of the diet concomitant to immunotherapy on nutritional status, muscle mass, and sarcopenia.

  4. Assessment of prealbuminemia [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    Assessment of prealbuminemia in g/L in order to evaluate the impact of the diet concomitant to immunotherapy on nutritional status, muscle mass, and sarcopenia.

  5. Assessment of C reactive protein [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    Assessment of C reactive protein in mg/L in order to evaluate the impact of the diet concomitant to immunotherapy on nutritional status, muscle mass, and sarcopenia.

  6. Assessment of sarcopenia [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    Sarcopenia will be assessed according to SliceOmatic software V5.0 and preestablished thresholds of skeletal muscle tissue (-29 to +150 Hounsfield units). Axial L3 sections will be used to measure the total muscle area (TMA) and calculate skeletal muscle index (SMI, cm²/m²). Sarcopenia is defined as SMI lower than a sex-based threshold (<55.4 in men and <38.9 in women).

  7. Assessment of Quality of Life (QoL) [ Time Frame: At screening and 9 weeks after diet initiation ]
    explore the evolution of Patient Reported Outcomes using EORTC QLQ 30 file in all treated patients.

  8. progression-free survival assessment [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    PFS is specified as the time between the date of the starting of the diet and the first date of documented progression, based on assessments (as per RECIST v1.1 criteria), or death due to any cause.

  9. Sarcopenic event-free survival (SFS) [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    SFS will be estimated from intervention starting.

  10. Overall survival (OS) [ Time Frame: from the first day of diet and up to 2 years from diet initiation ]
    OS is specified as the time between the date of the starting of the diet and the date of the death whatever the cause.
