EU Project Receives €15M to Bring mRNA Therapy to a Wider Audience

RNA EXPERT EU project news

An EU research project has launched with the aim of bringing mRNA treatments to a wider range of patients and diseases.

The EXPERT – Expanding Platforms for Efficacious mRNA Therapeutics – project is a collaboration among academics and industry experts from 11 countries who will work on a novel delivery system for messenger (m)RNA therapeutics to treat breast cancer and heart failure.

While it is still in early stages of clinical development, mRNA therapy is a promising technology that provides cells with the instructions to produce therapeutic proteins. Companies in the mRNA field such as Moderna in the US or BioNTech and CureVac in Germany have gathered a lot of funding and attention in recent years.

Our vision is to clinically develop mRNA therapeutics and to overcome the main obstacles mRNA-based therapy approaches are facing on their way to the market,” said project coordinator Raymond Schiffelers from Universitair Medisch Centrum Utrecht, the Netherlands. “The EXPERT approach could make mRNAs available off-the-shelf, enabling their use for more patients and different types of diseases.

Schiffelers told Labiotech that “changing from conventional protein-based drugs to mRNA would offer the advantage that you essentially are always delivering the same molecule.”

He explained that with conventional drugs and proteins, each drug formulation is dictated by the specific characteristics of the drug (eg, its solubility in water), whereas for mRNA the characteristics of the molecule are always the same, only the length and nucleotide sequence changes. This has the advantage that drug development projects would significantly gain speed.”

The project, which will receive €14.9 M in funding from the European Union’s Horizon 2020 Framework Programme over the next five years, launched in October with a meeting of the international partners from the Netherlands, Belgium, Norway, Sweden, Spain, Hungary, Ireland, France, Germany, and Israel.

These partners will work together to develop a proof-of-concept study for metastatic triple-negative breast cancer, in which specific mRNAs will instruct patients’ cells to produce proteins that can activate immune cells.

A requirement for this phase I study will be having “the complete chain from Good Manufacturing Practice sourcing of raw materials to reproducible scalabale production of well-characterized nanomedicines in place,” Schiffelers remarked.

A second study will investigate the use of mRNA for treating heart failure. In this case, patients will receive a cardiac-targeted mRNA molecule that will stimulate tissue regeneration in the heart without producing side effects elsewhere in the body.

Along with the production of mRNA therapeutics, the EXPERT project will also pursue new ways of delivering the medication to the target cells through nanomaterials designed to protect the mRNA payload from being destroyed by the patient’s immune system.

Indeed, Schiffelers noted that one of the study collaborators, eTheRNA, has already begun phase II trials where they overcame the challenge of getting mRNA to the target cell by isolating cells from the patient’s blood and directly inserting the mRNA via electroporation. This process uses electric fields to increase the permeability of the cell membrane. Once the mRNA is inserted, the cells are cultures and then transferred back to the patient.

Schiffelers said this process “has shown excellent proof of concept but requires a personalized and thus very costly approach for every patient.

He added: “By delivering the mRNA into the target cell with a generic off-the-shelf nanomedicine that is the same for every patient, significant cost reductions could be achieved and the whole concept allows wider application.”
