Valo Therapeutics Oy, the developer of novel, adaptable immunotherapy platforms for cancer and infectious diseases, announced the acquisition of intellectual property rights from the University of Helsinki, Finland, for the proprietary technology which utilises pre-existing immunity (PEI) against pathogens to enhance the therapeutic efficacy of ValoTx´s lead platform, PeptiCRAd.

This innovative approach takes advantage of existing acquired immunity (generated, for example, through vaccination against pathogens) by including pathogen specific peptides into the company’s PeptiCRAd platform. PEI technology utilizes body´s immunological memory and helps generate faster and stronger immune response in the tumour micro-environment, with the aim of enhancing the overall therapeutic efficacy of PeptiCRAd.
In well-established immunological tumour animal models, pre-immunisation with tetanus specific peptides significantly enhanced responses following subsequent vaccination with tumour-peptide coated oncolytic Adenoviruses; ValoTx’s PeptiCRAd technology, in combination with anti-PD1. The enhanced response was seen both in terms of T-cell response and significantly better tumour control. Three quarters of the animals treated in this way experienced complete inhibition of tumour growth.
Combining this approach with Valo’s PeptiCRAd technology could further enhance the immunological and tumour response across a range of cancers.
ValoTx’s highly experienced immunotherapy development team, lead by CSO Dr Sari Pesonen, is poised to commence a Phase 1 study using PeptiCRAd-1, a conditional replicating adenovirus incorporating OX40 ligand and CD40 ligand, coated with tumour specific antigens NY-ESO-1 and MAGE-A3, in three indications; melanoma, triple negative breast cancer and NSCLC.
Paul Higham, CEO of ValoTx, commented, “We have a strong and enduring innovation partnership with the University of Helsinki. This successful IP acquisition is part of our goal to strengthen and optimise our immunotherapy platforms, which have wide applicability in immuno-oncology, personalised cancer treatments and vaccines.”
Professor Vincenzo Cerullo, Professor of Biological Drug Development, Head of the Drug Research Program, and Group Leader at the world leading IVTLab at the University of Helsinki, said, “The PEI technology, developed at the University of Helsinki, is clearly synergistic with ValoTx’s core PeptiCRAd technology and opens up possibilities to successfully treat even more challenging, less immuno-responsive tumor types in the future.”
