Sys2Diag: A Revolution in Diagnostics

High-performance, affordable, and easy-to-use diagnostic tests—that is the mission of the Sys2diag laboratory. “A laboratory with a long history of innovation in medical diagnostics in France and Europe,” emphasizes its director, Franck Molina. A pioneer in innovation, but also a pioneer in public-private partnerships, the Laboratory for Modeling and Engineering of Complex Biological Systems for Diagnostics is the result of a collaboration between the CNRS and the Alcen Group. “This structure allows us to accelerate innovation by combining fundamental research with medical applications,” notes the recipient of the 2020 CNRS Innovation Medal. And applications abound at Sys2Diag. This is evidenced by the speed with which the company developed the EasyCov rapid saliva-based COVID-19 screening test—which is just the tip of the iceberg. Franck Molina has a whole arsenal of diagnostic tests up his sleeve, each more revolutionary than the last. Starting with the first blood-based psychiatric test developed by Alcediag for bipolar disorder and depression, which can even help assess and anticipate the risk of suicide attempts in patients.

While this one requires a blood draw, others are noninvasive. The secret behind them? Synthetic biology, which makes it possible to design and program artificial cells—like biomachines—to perform unnatural tasks. The result: self-tests that can be performed anywhere without having to go through a laboratory. Sys2Diag has thus partnered with Skillcell to develop the world’s first urine test for insulin resistance, called IDIR. “It’s the first pre-diabetes test, which means you can identify a risk of diabetes even before it develops.”

These tests will also be available… at stadiums, thanks to a saliva-based concussion test that can be used in real time during a game. “It allows us to objectively assess the severity of a concussion to determine the appropriate follow-up care, whether for professional players, amateurs, or even children,” explains Franck Molina, who has successfully turned this idea into reality. The researcher is now working on a groundbreaking test aimed at objectively measuring… well-being. “We’ve identified the relevant markers, but we can’t talk about them just yet.” To live happily, let’s keep it under wraps.

Ciloa: Packages Full of Therapeutic Promise

These tiny natural vesicles could well revolutionize medicine, and yet just a few years ago, no one would have bet on them. “For a long time, exosomes were considered the cells’ trash cans, ” recalls Robert Mamoun. He sees them quite differently. “In fact, an exosome is more like a package in the mail.” Why such an analogy? “We can modify both the proteins on its surface and those inside it, which makes it a package whose destination address and contents can both be changed.” The Inserm virologist recognized the full therapeutic potential of these properties as early as 2008. “Thanks to exosomes, we can, for example, mimic a virus that would have no pathogenic potential—that’s the basis for an ideal, completely natural vaccine.”

To explore this potential, Robert Mamoun founded the company Ciloa in 2011 with virologist Bernadette Trentin; the company was incubated at the University of Montpellier for eight years. And while Big Pharma companies have now recognized the value of exosomes, the Montpellier-based company remains “the oldest and most experienced in the world in this field of research.”

This research is not limited to vaccines; it also enables the development of therapeutic antibodies and new drugs, particularly in oncology. “We can attach a targeting moiety to the exosome, which can then be used to deliver an anti-cancer drug directly into the tumor. This allows for a more targeted—and therefore more effective—treatment while minimizing side effects, ” explains Robert Mamoun. Another target for exosomes is diabetes . “Our technology delivers a protein that acts at the root cause of diabetes by preventing insulin resistance—it’s very effective.” With a patent filed in 2021, Ciloa is at the forefront of this research and hopes to begin clinical trials in humans by the end of 2023.

Biodol: Relieving Chronic Pain

This offers hope of relief for the 7 to 9% of the population who suffer from chronic neuropathic pain—that is , “pain caused by nerve damage that has lasted for more than three months and persists even after the underlying cause has been treated, ” explains Jean Valmier. This “pain-disease” against which no medication is truly effective… for now. The researcher at the Montpellier Institute of Neurosciences (INM) has made a major breakthrough in understanding the mechanism responsible for this persistent pain. One of the keys to this breakthrough is FLT3, a receptor located on the neuron that is activated by a molecule called FL. “It is their interaction that triggers a chain reaction in the sensory system, leading to chronic pain. If we inhibit this receptor, the pain disappears.”

All that remained was to find that elusive inhibitor to silence the pain… To achieve this, Jean Valmier founded Biodol Therapeutics in 2015 with Fabien Granier and Didier Rognan. Thousands of molecules tested and four patents later, the company—which now has six employees—is the only one in the world working on these drug candidates. “We’re quite confident because we have two chemical series yielding very satisfactory results and at least one molecule that should be selected as a preclinical candidate by the end of 2022, which means that human trials could begin in 2024.”

A glimmer of hope is on the horizon for the nearly 4 million patients in France who live with pain every day. “ This is a huge public health issue, ” emphasizes Jean Valmier. “For patients, of course, but also for doctors who are at a loss because there’s not much they can do, and finally for the pharmaceutical industry, because a drug like this would be a blockbuster, as they say.” A Montpellier-based blockbuster, coming soon to theaters.

SeqOne Genomics: More Targeted Treatments Through Personalized Medicine

Understanding the specific characteristics of a disease to provide better care for patients is the goal of personalized medicine. This approach requires access to that “personalized blueprint”—each person’s genome—and the ability to decipher and interpret the thousands of mutations scattered throughout our DNA sequences. This is where the startup SeqOne Genomics comes in, offering high-performance genomic data analysis solutions for personalized medicine. Its goal is to improve clinical care for patients with cancer and rare and hereditary diseases. Founded in 2017 with support from SATT AxLR, the University of Montpellier, and Inserm, the company has already won numerous awards, such as the iLab Prize and the Hélène Starck Prize—which honors young researchers supported by the ARC Foundation—and boasts a strong position in the French market. This winning model has propelled SeqOne Genomics to a new milestone in early 2022, as the company raised 20 million euros to accelerate the deployment of genomic medicine. The company aims to build on this success by investing in a new area of development: “the market for biopharmaceutical companies developing new therapies, ” says Jean-Marc Holder, Head of Strategy and Innovation at SeqOne Genomics. The promise of more targeted treatments through a better understanding of disease mechanisms is also what personalized medicine is all about.
