The data support the potential of PDC*lung01 as a synergistic partner to existing immunotherapy regimens.
ESMO Annual Meeting 2022
Poster Presentation | September 12, 2022
Title: Open-label, dose-escalation, phase I/II study to assess the safety, tolerability, immunogenicity and preliminary clinical activity of the therapeutic cancer vaccine PDC*lung01 with or without anti-Programmed Death-1 (PD-1) treatment in patients with non-small-cell lung cancer (NSCLC)
Authors: J. Vansteenkiste, I. Demedts, E. Pons-Tostivint, B. Biesma, F. Borm, B. Colinet, K. Cuppens, S. Derijcke, L. Greillier, J. Jurgens, D. Moro-Sibilot, M. Pérol, M. Sebastian, M. Skrzypski, W. Theelen, C. Van De Kerkhove, M. Collodoro, J. Plumas, C. Debruyne, A. Sibille
This poster reported interim findings from the ongoing Phase I/II clinical trial evaluating PDC*lung01 in NSCLC patients. The multi-center, open-label, dose-escalation study assessed safety and tolerability, immunogenic activity, and early clinical signals — both as a standalone vaccine and in combination with anti-PD-1 therapy. Results demonstrated a favorable safety profile and encouraging immunological responses, reinforcing the clinical rationale for continued development.

Oral Presentation | May 10–12, 2022
Title: Priming and expansion of functional antitumor T-cells in melanoma patients: results of phase I clinical trial with GeniusVac-Mel4, an innovative cancer vaccine based on a plasmacytoid dendritic cell line
Authors: J. Charles, L. Chaperot, D. Hannani, J. Bruder Costa, I. Templier, S. Trabelsi, H. Gil, A. Moisan, V. Persoons, H. Hegelhofer, E. Schir, J.-L. Quesada, C. Mendoza, C. Aspord, O. Manches, P. Coulie, A. Khammari, B. Dreno, M.-T. Leccia, J. Plumas
This eTalk presented results from the first-in-human Phase I trial of GeniusVac-Mel4 in melanoma patients. The study demonstrated that the PDC*line-based cancer vaccine successfully primed and expanded functional antitumor T-cells — providing clinical proof-of-concept for the platform’s ability to elicit meaningful antigen-specific immune responses in cancer patients. These results formed a cornerstone of the PDC*line Pharma clinical strategy.
18th CIMT Annual Meeting — eTalk
Oral Presentation | May 10–12, 2022
Title: The retroviral engineering of a human plasmacytoid dendritic cell-based vaccine allowed the priming and expansion of multispecific viral and tumor antigen-specific T-cells in multiple HLA contexts
Authors: K. Lenogue, A. Walencik, K. Laulagnier, J.-P. Molens, H. Benlalam, B. Dreno, P. Coulie, M. Pule, L. Chaperot, J. Plumas
This eTalk presented preclinical data on the retroviral engineering of the human PDC*line platform, demonstrating the ability to generate multispecific immune responses against both viral and tumor antigens across a broad range of HLA types. The findings highlight the versatility and broad applicability of the PDC*line technology — a key feature underpinning its potential as a platform for multiple oncology indications and diverse patient populations.
2021
European Lung Cancer Virtual Congress (ELCC 2021)
ePoster Presentation | March 25–27, 2021
Title: An open-label, dose escalation, Phase I/II study to assess safety, tolerability, immunogenicity and preliminary clinical activity of the therapeutic cancer vaccine PDC*lung01 with or without anti-Programmed Death-1 (PD-1) treatment in patients with non-small cell lung cancer (NSCLC)
Authors: J. Bennouna, A. Sibille, C. Debruyne, B. Colinet, I. Demedts, S. Derijcke, L. Greillier, J. Jurgens, H. Lena, D. Moro-Sibilot, M. Pérol, X. Quantin, N. Reinmuth, M. Sebastian, M. Genin, J. Plumas, J. Vansteenkiste
Presented at the European Lung Cancer Congress, this ePoster provided early-phase data from the PDC*lung01 clinical trial in NSCLC patients. Early results confirmed the vaccine’s tolerability and immunogenic activity, establishing a solid safety baseline for the Phase I/II dose-escalation program. The multi-center multinational study included leading thoracic oncology centers across Europe.
2017
ESMO Immuno-Oncology Congress 2017
Poster Presentation | December 7–10, 2017
Title: Priming and expansion of neo-antigen specific-T cells thanks to an off-the-shelf cell-based drug product
Authors: J. Plumas, P.M. De Sousa Alves, E. Leplus, L. Chaperot, D. Hannani
This early-stage poster presented preclinical proof-of-concept data demonstrating that the PDC*line platform is capable of priming and expanding neoantigen-specific T-cells. The results laid the scientific groundwork for the PDC*Neo program and validated the platform’s potential for personalized neoantigen-based cancer immunotherapy — a highly promising frontier in precision oncology.
