Based in Grenoble, France, NH TherAguix was
founded in 2015 by a former ESRF employee,
with the goal of bringing an innovative cancer
nanodrug, AGuIX, to market. Six years later, it has
18 employees and is engaged in nine clinical trials,
including phase-two clinical trials.

Géraldine Le Duc began working at the ESRF’s ID17
biomedical beamline in 1997, aiming to develop
a single drug that could act both as a contrast
agent for magnetic-resonance imaging (MRI)
and a radio-enhancer for radiotherapy. Radio-
enhancers improve the ability of X-rays to kill
tumours. By combining one with a contrast agent,
Le Duc’s idea was that radiotherapy could take place
just af ter an MRI scan, improving the precision of
X-ray delivery and saving more healthy tissue from
X-rays. She eventually developed AGuIX based on
the element gadolinium. This contrast agent was
being researched by an independent ESRF user,
Olivier Tillement at the University of Lyon in France;
together, he and Le Duc discovered its radio-
enhancing ef fect.
In 2015, Le Duc lef t the ESRF in order to create
NH TherAguix and bring AGuIX to market. In its
phase-one clinical trials focused on brain
metastases, 13 out of 14 tested patients exhibited
a clinical benef it. It plans an initial public of fering
on the Euronext Growth market in Paris.

Very few companies developing cancer drugs
f ind success But I thought if you dont try af ter
working for 20 years in the lab what else can
you of fer The ESRF was very important to my
story so important that it coowns one of our
patents It is a melting pot of users working on
different types of nanoparticles which helped
me f igure out what worked and what didnt Also
at a synchrotron you can explore a much larger
range of Xray parameters than at a hospital Xray
machine and therefore be more creative with
protocols We hope that AGuIX will be registered
by 2025 to improve cancer survival rates and
quality of life
