Medical Director

The Medical Director takes care of all the medical aspects related to the treatments and clinical studies of Pherecydes Pharma.

She is also involved in the regulatory aspects of phage therapy.


Patrick Champion-Arnaud

Patrick Champion-Arnaud, CMO

Patrick is an expert in biologicals manufacturing. Before joining Pherecydes, he was Scouting Manager at Valneva in Nantes, a Biotechnology Co. involved in vaccine development. Patrick has been working on flu, pox, herpes, lenti, adeno… viruses to name a few.

His knowledge in virology coupled to vaccine manufacturing process development is a good combination to develop pharmaceutical bacteriophage drugs.

Patrick worked also at the Harvard Medical School (Boston, MA, USA) after getting his PhD in molecular virology from Nantes University (France).

Cindy Fevre

Cindy Fevre, CSO

Cindy is a microbiologist, expert in bacteriology. She got her PhD from Pierre & Marie Curie University at the Pasteur Institute (Paris, France). She studied antibiotic resistance, virulence and genetic diversity of Klebsiella genus. Afterwards, she worked on other major clinical pathogens such as Listeria and Staphylococcus aureus.

Before joining Phercydes Pharma, Cindy also developped a new Phage Display method and acquired a deep knowledge in bacteriophage biology and genomics.

Through an international experience (UMC Utrecht, Netherlands) she managed research collaboration with industrial potential and led a team of pluridisciplinar and multicultural researchers.

Laure Saujet

Laure Saujet, R&D projects coordinator

Laure replaced Cindy Fevre, CSO, during her maternity leave at Pherecydes Pharma, from December 2017 to September 2018. She is currently a R&D projects coordinator.

She has a PhD on microbiology obtained in 2013 at the Pasteur Institute. After her thesis, she worked on hydrogenases at the CEA of Saclay for one year. Then, she worked as a synthetic biology project manager.

As first employee of this start up, she was responsible of the development of genetically modified bacteriophages specifically targeting adherent invasive E. coli implicated in Crohn's disease.

She published 12 scientific articles including 3 in first author.

Gaëlle Demarre

Gaëlle Demarre, Senior Scientist

Gaëlle become a member of the Pherecydes Pharma team in May 2018.

She obtained a PhD at the Pasteur Institute (Paris) studying the natural vectors of antibiotic resistance, responsible for their dissemination.

During 4 years, she put forward her skills at the National Institutes of Health (USA, Bethesda), on Vibrio cholerae.

After roaming, she joined the CNRS, then the Collège de France (Paris, France) where she studied an invasive and adherent strain of Escherichia coli associated with the Crohn disease.

Gaëlle brought up a major public health problem: Bacteria sensitive to antibiotics may become persistant in presence of antibiotics and so survive to those antibiotic treatments.


Angella Nzonza

Angella Nzonza, Head of Quality Control

Angella joined Pherecydes Pharma in December 2017. She sets-up bacteriophage quality control tests for therapeutic treatments. She is also working on the development of analytical methods to characterize bacteriophages.

She obtained a PhD in Virology from Paris Diderot University in Mars 2014. Her thesis work led to the filing of a patent and the publication of 2 scientific articles.

She then worked at Sanofi Pasteur as a Scientific Manager consultant in the European Analytical Research Department from 2014 to 2016. Her mission was to optimize several QC analytical methods applied to marketed vaccines.

Afterwards, Angella worked as a Biochemistry engineer for 5 months at Yposkesi company, where she was responsible for methods validation and development for gene therapy drugs analysis (Adeno-Associated Virus).

Héloïse Fonteneau

Héloïse Fonteneau, Quality Assurance Project Manager

Héloïse worked for 7 years on the scaling-up of bacteria production at Sanofi; the development of vaccines produced on avian stem cell at Valneva; as well as the management of R&D projects for immunoassays at Beckman Coulter.

By integrating Beckman Coulter's Scientific Development Program, Héloïse used her international skills (Boston, Los Angeles France) and was able to develop her knowledge of FDA and cFDA requirements (IVD) as well as ANSM requirements (BPF).

She joined us in February 2018 to set up the Quality Assurance Department. She now assists the quality director Magali Vidal-Engaurran in managing the operational quality and ensuring among others the quality of subcontractors and suppliers.
