Adagene Appoints Professor Aurélien Marabelle to Scientific and Strategic Advisory Board

- Brings deep insight in tumor-specific Treg depletion for anti-CTLA-4 therapies delivered intratumorally to overcome dose dependent toxicities -

- Expertise contributes to Adagene’s novel anti-CTLA-4 therapies delivered systemically at higher and repeated doses with compelling safety -

SAN DIEGO and SUZHOU, China, March 05, 2023 (GLOBE NEWSWIRE) --  Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a company transforming the discovery and development of antibody-based therapies, today announced the appointment of Professor Aurélien Marabelle, MD, PhD, to its Scientific and Strategic Advisory Board (the “SAB”). Professor Marabelle is a physician-scientist with expertise in oncology and immunology. His clinical practice is dedicated to early phase clinical trials of cancer immunotherapies with strong translational evidence within the Drug Development Department (DITEP) of Gustave Roussy Cancer Center in France. He leads a translational research laboratory (LRTI) within the INSERM U1015 with a focus on mechanisms of action of immune targeted therapies.

Professor Marabelle commented, “As CTLA-4 is upregulated on the membrane of regulatory T-cells (Tregs) upon T-cell receptor engagement, it is therefore an opportunity to target and deplete tumor-specific Tregs specifically within the tumor microenvironment (TME) for this proven pathway. Adagene’s SAFEbody precision masking technology enables systemic delivery of CTLA-4 treatment similar to intratumoral delivery to reach a higher concentration at the tumor site, enabling tumor-specific Treg depletion for effective immunotherapy.”

In addition to his clinical and translational research, Professor Marabelle is also the director of the Clinical Investigation Center BIOTHERIS dedicated to intratumoral immunotherapies (INSERM CIC1428). He is a full professor of Clinical Immunology at the University of Paris Saclay. He was initially trained as a scientist in the Ecole Normale Supérieure de Lyon and King’s College London and as a clinician at the Léon Bérard Cancer Center in Lyon, France. He did his post-doctoral research fellowship in the laboratory of Professor Ronald Levy at Stanford University on strategies to overcome the resistance to immune checkpoint targeted therapies. Professor Marabelle is also an active member of ESMO, ASCO, AACR, SITC, EATI and is the current President of the French Society for Cancer Immunotherapies (FITC). He has published more than 250 peer-reviewed publications.

“Professor Aurélien Marabelle pioneered the intratumoral delivery of anti-CTLA-4 therapy in clinic as a way to overcome the safety issues of anti-CTLA-4 therapy delivered systemically. This approach increased the effective concentration of anti-CTLA-4 in the TME to achieve statistically significant tumor-specific Treg depletion as a key driver for anti-CTLA-4 therapy, following Professor Marabelle’s years of preclinical and translation studies,” said Peter Luo, Ph.D., Co-Founder, Chief Executive Officer and Chairman of the Board of Adagene. “Reflecting the vanguard of science at Adagene, we have persistently pursued and implemented seamless translational studies using the same molecules targeting the same epitope across different species for our anti-CTLA-4 programs. We have observed an excellent correlation from both programs, and , in safety and efficacy both as single agents and in combination with anti-PD-1 in our ongoing phase 1b/2 studies. Professor Marabelle’s deep expertise in translational and biomarker-driven trial design in anti-CTLA-4 therapy will help further strengthen our understanding of tumor-specific Treg depletion in the development of our novel anti-CTLA-4 therapies with strong safety and tumor-specific Treg depletion through systemic delivery.”
