Eurostars-funded REPRINT consortium reaches milestones with evidence of complete tumor regression induced by dendritic cell reprogramming


Zurich, Switzerland – 11 April 2023 – InSphero, a Swiss SME, announces today, together with the REPRINT project
partners, Asgard Therapeutics (SE, project coordinator), Lund University (SE) and Antineo (FR), the achievement
of proof-of-principle for using dendritic cell reprogramming to kick start in-vivo anti-tumor immunity. This joint
successful milestone comes as the biggest output of the second in-person meeting hosted by InSphero and held
last week in Zurich.

The REPRINT (REPRogramming tumor INTo Immune Cells: a revolutionary gene therapy to treat cancer) project
is a research initiative funded by the EUROSTARS program with the aim to develop an innovative off-the-shelf
cancer immunotherapy based on Asgard Therapeutics' proprietary in-vivo reprogramming technology. During
these 1,5 years of activities, the four partners have provided extensive proof-of-principle for reprogramming
tumor cells into antigen-presenting dendritic cells as a way to restore tumor immunogenicity, using both ex-vivo
3D and in-vivo models. Remarkably, reprogrammed cancer cells have the ability to activate local and systemic
polyclonal tumor-specific immune responses, leading to complete tumor regression in animal models.

Cristiana Pires, PhD, Co-Founder and CEO of Asgard Therapeutics, said: “Since its launch in October 2021, the
REPRINT project has made remarkable progress towards the development of a new cancer immunotherapy
based in in-vivo reprogramming of tumor cells. We are thrilled with the recent in-vivo results, which showed
that reprogramming can cure tumor-bearing animals! In addition, Asgard has selected the final platform to
enable efficient delivery of the reprogramming factors to tumors in-situ and provided extensive validation of
reprogramming from a multitude of human patient-derived tumor cells, which supports the platform potential
of our lead program. There're also exciting results coming supporting the ultimate vision for our lead program.
During our recent in-person meeting, we had the opportunity to delve over the progress made and align
priorities for future work with our consortium partners. It has been an absolute pleasure to collaborate with
such an outstanding team to accelerate the development of our pioneering reprogramming therapies.”

Wolfgang Moritz, Head of Ext. Collaborations and IP at InSphero AG said: "The consortium meeting in Zurich
was a great success. We are honored to be a part of this historic project and we are excited to work with such a
talented group of experts in the field. We are reporting the achievement of two major milestones at this
meeting. First, we efficiently replicated tumor cell reprogramming into dendritic cells in our ex-vivo 3D
Microtissue Platform. Using high content confocal imaging, we were able to visualize emerging dendritic cells
and assess the efficiency of viral transfection and reprogramming. Second, we have successfully tested the
prototype of a new plate. The AKURA™ TWIN plate accommodates the tumor models, together with liver or
pancreatic islet microtissues, both in coculture with immune cells in adjacent wells, connected by a small
channel. This breakthrough will enable the simultaneous evaluation of on- and off-target effects of tumordendritic cell reprogramming. InSphero's proprietary in vitro technology will validate clinical benefits of a new
therapeutic approach and de-risk potential safety concerns.”

Filipe Pereira, PhD, Professor and Group leader at Lund University commented: “At this consortium meeting
in Zurich, we were excited to discuss progress and define objectives with the entire REPRINT team for the cDC1
reprogramming approach created in our lab. We are grateful to join forces with this great team to pave the way
for an entirely new cancer immunotherapy platform based on cellular reprogramming. At this meeting, we
discussed the in-vivo results which showed that tumor-bearing models can be cured by our reprogramming
strategy! This is a milestone providing proof-of-principle for a new cancer immunotherapy based on in-vivo
reprogramming of tumor cells. We also showed that reprogramming progressed in human spheroid models with or without the presence of an immunosuppressive component of the tumor microenvironment. We are looking
forward for development of the second half of this exciting project.”

Marie Tautou, PhD, Study Director of Antineo added: “In the context of this consortium, we are thrilled to
announce great progress in the establishment of 3D bioprinted cancer cells cubes that have allowed us to show
efficient in vitro reprogramming of cancer cells into dendritic cells. In parallel, we have started experiments
aiming to show the ability of Asgard's gene therapy to reprogram tumor cells in vivo and we have exciting
promising results. We are now focusing on the project's next steps, which are to show the innocuity of the
strategy in mice models. We are very pleased to be part of such a ground-breaking project.”
The Eurostars programme supports innovative international projects led by R&D-performing SMEs and is cofunded by the Eurostars partner states and the EU (through Horizon 2020). In October 2021, Asgard Therapeutics
announced that together with the other three partners it has been awarded the Eurostars project REPRINT
(project number E!115376). The three-year proposal was ranked #4 out of 644 European applications for
Eurostars Cut off 15 and thereby secured a grant of 2 million euros.
