Boost Immunity

STING activating Virus-Like Particles to treat patients that do not respond to conventional immunotherapy.

About Stimunity

Stimunity is a preclinical-stage startup company which develops best-in-class drugs on the STING pathway to activate the innate immune system. Our drugs stimulate patients' immune system to fight back infectious pathogens or cancer.

Our technology is based on high level academic research work from prestigious institutions: Institut Curie, the French National Institute of Health and Medical Research (Inserm) and University of Oxford.

We raise 2M€ as seed investment from Portage Biotech (NASDAQ:PRTG), a public listed venture company that invests in early-stage immuno-oncology assets to move them through clinical trials.

Nicolas Manel

Scientific Advisor & Founder

Dr. Nicolas Manel is Director of Research at INSERM and Group Leader at Institut Curie. His lab focuses on the molecular mechanisms of innate immunity in cancer and infectious diseases. His lab discovered a "Trojan horse" mechanism that activates the STING innate immune pathway by way of viral particles (Science 2015), which is at the core of the technology developed by STIMUNITY. Other discoveries in his lab include the identification of the essential role of the cGAS-STING pathway in HIV immune recognition (Immunity 2013), a mechanism of division of labor across dendritic cells to induce antiviral immunity (Science Immunology 2017) and the anti-proliferative activity of disease-mutated STING in T lymphocytes (J Exp Med 2017). He holds a PhD in biology from University of Montpellier and he is a former student of Ecole Normale Supérieure de Lyon. He was trained as a postdoctoral fellow in the lab of Dan Littman at New York University. As a trainee during his PhD & postdoc, he identified the receptor for the Human T cell Leukemia/Lymphoma Virus (Cell 2003), he elucidated the mechanism of human Th17 CD4+ T cell differentiation (Nature Immunology 2008) and he discovered that HIV-1 evades a potent innate immune sensing mechanism in dendritic cells (Nature 2010). Currently, his lab at Institut Curie explores novel mechanisms of innate immunity in self and non-self recognition, focusing on the cGAS-STING pathway. His lab also pursues an ambitious R&D program in collaboration with Stimunity.

Ian Walters

Chairman of the Board

Dr. Walters has 20+ years of oncology/immunology drug development experience. He currently acts as CEO, Chairman or CMO to 7 immuno-oncology companies. He spent seven years at Bristol-Myers Squibb (BMS), where he led clinical research and matrix development teams. During his tenure there he contributed to the development of multiple immuno-oncology products (Yervoy®/anti-CTLA4 and Nivolimumab/anti-PD1), as well as the licensing and partnering strategy for other immuno-oncologic agents. He has worked in multiple biotech companies on corporate development, translational medicine, clinical development and medical affairs. He has been also a consultant to biotech, pharma and investment companies specializing in the evaluation, prioritization, and development of innovative technologies in the treatment of severe diseases. Before entering the private sector, Dr. Walters was a lead investigator at the Rockefeller University and initiated cutting edge immunology research to understand the mechanism of action of several compounds. He received his MD from the Albert Einstein College of Medicine and an MBA from the Wharton School of The University of Pennsylvania.

Scientific Advisor

Dr. Robert Kramer is a PhD Pharmacologist with postdoctoral experience at the National Institutes of Health in the USA, and also held the position of Assistant Professor of Radiation Oncology at Harvard University prior to joining the pharmaceutical industry in 1991. He has since served as Vice President and head of cancer drug discovery at Bristol Myers Squibb (1997-2010) and then Janssen Pharmaceuticals (2011-2015). He championed BMS' early adoption of immuno-oncology and was instrumental in the acquisition of the pioneering biotechnology company, Medarex, in order to acquire the rights to ipilimumab (anti-CTLA4) and nivolimumab (anti-PD1), two drugs dominating the immuno-oncology market. During his career he supervised more than 35 drugs from discovery to the clinic. Currently, Dr. Kramer serves as a consultant to the Pharmaceutical, Biotech and Investment community.

The Technology

Unique immuno-modulator platform based on Enveloped Virus-Like Particles

Immuno-oncology is driven by immune checkpoint inhibitors (ICI) that showed unseen long-term survival for patients with advanced/metastatic cancer. However, these therapies only work for 20-30% of the patients. The industry is now looking for new drugs to improve this response rate.

STING is a promising way to activate innate immunity in patients with cancer. Preclinical studies demonstrate that STING activation drives a potent and specific T cell response against tumor cells. It also restores ICI efficacy when used in combination.

Our approach using VLP is unique in the field and brings major benefits to the patients:

1) Preferential targeting of dendritic cells
Targeting the dendritic cells is key in STING activation to improve tumor antigen presentation and to avoid cell-specific side effects like inflammation or even necrosis.

2) Unlock systemic administration
Unlike 1st generation of STING agonists that were limited to intratumoral administration, systemic administration unlocks the possibility of multiple rounds of administration and long-term treatment. It also opens possibility for therapeutic use in all tumor indications.

Preclinical data are available preprint on BiorXiv.
