Clinicobiome, the microbiota clinic

In the fight against cancer, Professor Laurence Zitvogel's research team has focused for almost a decade on the role played by the intestinal microbiota in the onset and treatment of cancers. Adopting a pioneering approach in this area of research, her team has highlighted a correlation between the inefficacy of immunotherapy and chemotherapy treatments and intestinal microbiota imbalance in certain patients.
Based on these findings, Gustave Roussy has launched the Clinicobiome medical-scientific programme, taking a crucial step forward and developing new therapeutic approaches to cancer by offering:
  • Four clinical trials involving microbiota intervention to significantly improve treatment efficacy
  • A wide-ranging epidemiological study involving biological specimens to diagnose intestinal dysbiosis more efficiently and assess its impact on immunity and metabolism as well as its prognostic value
These studies will:
  • Investigate various microbiota and their role in cancer treatment
  • Define microbial metagenomic signatures to predict resistance to cancer therapies
  • Investigate how certain micro-organisms affect the immune system and metabolism of patients
  • Prove the concept that microbiota-based treatments can overcome resistance to immunotherapies
The Clinicobiome team comprises doctors, pharmacists, research scientists, engineers and technicians dedicated to this ambitious project and capable of using cutting-edge technologies in the field of medical research.

The 5 projects making up the Clinicobiome programme:


A prospective epidemiological study to assess intestinal dysbiosis in relation to cancer and primary resistance.
Aims: to validate microbial signatures capable of predicting treatment response and to create a biobank of data and rapid diagnostic kits for intestinal dysbiosis.


A phase II pilot study to assess the ketogenic diet in combination with nivolumab plus ipilimumab in the management of metastatic renal cell carcinoma.

Aim: to demonstrate that a ketogenic diet can improve the efficacy of prescribed immunotherapy in the management of advanced/metastatic renal cell cancer by 20%.


A non-randomised phase II trial to assess CAPOX-bevacizumab plus pembrolizumab as first-line therapy in the treatment of metastatic colon cancer.

Aim: to review the efficacy of CAPOX bevacizumab chemotherapy in the treatment of colon cancer with MSS (microsatellite stability) when administered concomitantly with pembrolizumab to a subpopulation of MSS patients with adjuvant ileal microbiota.


A randomised phase II study to assess faecal microbiota transplantation combined with cemiplimab versus the investigator's choice in patients with advanced lung, kidney and bladder cancer proving resistant to anti-PD-1/PD-L1 due to the use of antibiotics.

Aim: to demonstrate that faecal transplantation can restore an objective response in patients treated with antibiotics and proving resistant to immunotherapy.


A randomised phase II study combining Akkermansia pp2261 with pembrolizumab as first-line treatment in the management of non-small cell lung cancer.

Aim: to establish whether OncoBax - Akkermansia pp2261 - is capable of overcoming resistance to pembrolizumab as first-line therapy in cases where PDL-1 >50%.
