INRAE and MaaT Pharma build on the success of their long-standing partnership with the entry of drug-candidate MaaT013 into phase 3 clinical trial

PRESS RELEASE - On March 28th, 2022, MaaT Pharma announced the launch of a pivotal clinical trial for MaaT013, its microbiome ecosystem therapy, dedicated to treating acute Graft-versus-Host Disease. MaaT Pharma was established based on INRAE’s high-level microbiome science, with particular scientific support from Dr. Joël Doré, one of the world's most renowned researchers in the field. After just 7 years since its creation, MaaT Pharma has become the first biotech company in the world to initiate a Phase 3 trial in haemato-oncology with a microbiome-based biotherapy. The partnership is an example of a successful technology transfer from the laboratory to the patient's bedside, opening new treatment avenues for patients with life-threatening diseases.

MaaT Pharma (EURONEXT: MAAT – the “Company”), a French clinical-stage biotech and a pioneer in the development of microbiome-based ecosystem therapies dedicated to improving survival outcomes for patients with cancer, announced on March 28th, 2022, the inclusion of the first patient in a pivotal Phase 3 clinical trial, potentially the last step of clinical development before marketing authorization, evaluating MaaT013 for the treatment of acute gastrointestinal Graft-versus-Host Disease (aGvHD), a serious complication following stem cell transplantation. Every year, more than 10,000 people are diagnosed in Europe and in the United States of America[1], and the prognosis for the patients with the most advanced form is poor with a mortality rate of up to 80%[2] in the first year. This new milestone for MaaT Pharma, the first Euronext-listed company developing microbiome-based therapies, builds on the success story of its founding partnership with INRAE initiated in 2014, in particular via the scientific support agreement[3] between MaaT Pharma, INRAE and Dr. Joël Doré, INRAE Research Director, Scientific Director of Métagénopolis, author of nearly 500 publications, and one of the world's most cited authors in the microbiome sphere today.

At the end of 2014, following a project development period as an entrepreneur-in-residence with Seventure Partners, Hervé Affagard, currently CEO, founded MaaT Pharma alongside Dr. Joël Doré, now MaaT Pharma's Scientific Advisor. As early as 2015, MaaT Pharma and INRAE co-filed three patents, for which the Company now holds exclusive exploitation rights. These patents are also at the root of the development of the Company’s native products, MaaT013 and MaaT033, both currently in clinical trials.


"Microbiome science has been at the heart of my research for more than 30 years. INRAE has established itself first as a pioneer, then as an international center of excellence in the field. In 2021, for example, INRAE was the 5th largest academic player in the world in terms of microbiome-related patents. In my opinion, the rapid growth of MaaT Pharma, which has entered a Phase 3 clinical trial, perfectly illustrates the efficient and successful transition from pioneering science to innovative therapeutic development for the benefit of patients. Through my research, I hope to contribute to the fast emergence of a new medicinal modality, that takes into account the symbiotic relationship between human health and the microbiome," said Dr. Doré.

Following the advent of metagenomics[4], the research produced at INRAE on the gut microbiome has led to unprecedented results disrupting our understanding of the digestive ecosystem, and opening novel avenues for improving the health of millions of patients worldwide suffering from cancers, metabolic diseases, or inflammatory diseases to name just a few of the potential indications.

MaaT Pharma has developed a portfolio of three products since its creation including two currently in clinical phases. The Company has initiated five Phase 1 and Phase 2 clinical trials, consolidated its patent portfolio (including 13 international patent families), and raised a total of €83 million. The Company currently employs 45 people and MaaT013 has been administered to more than 100 people with aGvHD in a Phase 2 clinical trial and in an ongoing compassionate access program[5] in France.


Hervé Affagard, CEO and co-founder of MaaT Pharma commented, "Since our foundation, we have been looking to develop the microbiome ecosystem in France and have forged partnerships with medical and scientific centers of excellence as well as with renowned industrial players to develop the Company. In 2016, we launched our first clinical trial just 18 months after the company's creation, and we have since strengthened our position as a pioneer in microbiome-based therapies in oncology. Our translational expertise allows us to rapidly transform science into groundbreaking and safe drug candidates, with the support of our scientific partners, to improve survival outcome for cancer patients."

The collaboration between these two pioneers continues to move forward with the formation of industry structures and the growth of national expertise in the microbiome space in Europe with the Alliance Promotion Microbiote (APM), of which both organizations are among the co-founders. APM is an association under the French law of 1901 and includes 25 private and public players (companies, clusters, research institutes, investment funds), of which Hervé Affagard was elected president in January 2022. APM aims to contribute to making France, a pioneering nation in microbiome research and engineering, into a European leader to meet the current and future challenges of this sector recognized in 2021 as a priority in the "Health Innovation Plan 2030 ".

Microbiota, the intestinal revolution - Feed your microbiota

PRESS REPORT - At no other time in history has it been easier to access food. Never before have our forks been in closer proximity to such an abundance of things to eat. And yet, nutritionists are constantly warning us about bad eating habits. Welcome to one of the paradoxes of modern societies. Diets that are too high in fat and sugar and too poor in fibre have led to an uptick in diseases such as diabetes, obesity and inflammatory bowel disorders. Researchers are discovering just how much our intestinal microbiota suffers from an imbalanced diet, and becomes less apt to protect us. A healthy diet, rich in fibres from a wide variety of food, contributes to the diversity and richness of bacterial populations, the equilibrium of their ecosystems, and therefore to overall health.

Joël Doré, for the love of microbes

Joël Doré is a research director in the Joint Research Unit for Food and Gut Microbiology for Human Health and scientific director of the MetaGenoPolis, both of which are part of INRA Île-de-France – Jouy-en-Josas. Doré's soft voice and modest demeanor cannot hide his scientific enthusiasm and love for shared knowledge. And what is his scientific speciality? The intestinal microbiota: he is dedicated to studying its every facet. We interviewed Doré, a passionate scientist who is toppling preconceived ideas about the microorganisms inhabiting the human body.

A rationale for dual therapy in the treatment of ulcerative colitis

PRESS RELEASE - Ulcerative colitis is a debilitating chronic inflammatory disease that can lead to the development of colon cancer. Its causes are poorly understood and existing treatments have variable results on a disease that remains incurable today. Data from 353 patients analysed by an INRAE team revealed the existence of four different states of the gut microbiota and four levels of inflammation. Based on a model built from this data, the scientists predict that acting on both the inflammation (anti-inflammatory treatment) and the state of the microbiota (microbiota transplantation, for example) would significantly increase a patient's chances of remission. These results, published on 8 September in the journal Gastroenterology, provide a rationale for the development of personalised dual therapy strategies which combine the two types of treatment.
