Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of the ORION study is to explore the changes of gut microbiota composition following MaaT013 administration and its impact on the immune system in GVHD patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The french regulatory authority ANSM approved in July 2019 the use of MaaT013, a pooled microbiome-based enema formulation, under a formalized named-patient use program in France called "Autorisation Temporaire d'Utilisation - ATU nominative protocolisée - ATUn" or Early Access.

The ATUn is indicated to provide a benefit in the treatment of patients with grade III-IV aGVHD:

* In case of initial resistance to CS alone or in association or in case of failure to other treaments
* In first-line therapy in association with CS in case of steroid-dependance (inability to taper CS dose \<0.5 mg/kg/d)
* In case of digestive aGvHD with overlap syndrome The objective of the ORION study is to explore the changes of gut microbiota composition following MaaT013 administration and its impact on the immune system in GVHD patients.

Blood and stool samples will be collected at each visit which explained why the study is thus categorized as research involving the human person with low risks and constraints clinical trial (RIPH2).

Patient population

The population of the study will be adult patients with GI-aGVHD grade III to IV undergoing MaaT013 treatment through named-patient use program ATUn (Early Access Program).

Blood and stool samples will be collected at each visit to analyse the gut microbiota and the immune cells.
