Mesenchymal Stromal Cells

GMP-compliant infrastructure and production in a hospital-setting of mesenchymal stromal cells from lipoaspirate for use in clinical trials.

Lead Partner: Region Örebro Län

Involved Partners: Region Västerbotten, VivaBioCell, AcouSort

Project aim: In this project, adipose derived MSCs will be used as a model system for minimally-manipulated cellular ATMPs produced in a hospital setting.  While transplant of minimally manipulated cells is standard therapy for many conditions eg. blood transplants, when autologous or allogeneic cells are returned to the body for a different essential function, they are now regulated as ATMPs. An example of this is the use of fat derived Mesenchymal Stromal Cells (MSCs) for treatment of xerostomia, chronic wounds, knee osteoarthritis and immunosuppressive treatment to graft vs host reactions.

Production of ATMPs requires infrastructures to achieve medicinal drug production compliant with EU legislation. Key roles and functions such as qualified person, quality controller and quality assurance need to gain knowledge and expertise in cell biologics, clean room technology, pharmaceutical quality systems and the application process for regulatory approval for the manufacturing of ATMPs from the national competent authority (Läkemedelsverket).

By developing a GMP-compliant production line using closed bioreactors, a scalable system for producing off-the-shelf/ready-to-use cell therapy products can be put in place. By using easy-to-operate scalable bioreactors for cell expansion and by developing robust GMP-compliant expansion methods, a cost-effective production can be up-and-running in a relatively short time frame.

This project ends with the initiation of clinical trials using expanded MSCs from closed bioreactors. Patients with xerostomia following radiotherapy will be treated in a randomized placebo-controlled study, with change in unstimulated whole salivary flow rate as primary outcome. Moreover, in a separate clinical trial, patients with chronic wounds will be treated with the same ATMP. Further applications are currently considered. Expected outcome overall from this project is access to cell based therapy for chronic diseases for Swedish patients, in a model system suitable for implementation in hospitals with GMP-facility access.

Interview with Project Leader

Hej Emma!

What is the need your Project addresses?

Although much excitement in advanced therapies comes from gene modified ATMPs like CAR-T treatments, those therapies often aim at small disease populations and/or rare disease. We feel the same excitement for more simple autologous cellular therapies that can treat large patient populations! With this project we want to explore treating common chronic diseases with a cell therapy product, locally produced in the Swedish health care system in an affordable manner.

What is your approach to meet the need?

We use Mesenchymal Stromal Cells (MSCs) as a model system for setting up GMP compliant production in the health care system, i.e. a university hospital. Working together with our partners, we want to use the latest technology for culturing in closed bioreactors and then finding/analyzing extracellular biomarkers to use for potency assays.

How will this improve Sweden’s capabilities within ATMPs?

This project´s deliverables are amongst others infrastructure and knowledge on how to set up clinical trials using cell therapy products manufactured in a hospital setting in closed bioreactors. This information will be disseminated to any interested party, and we want to help with the implementation of manufacturing cellular therapies at hospitals for treating diseases! Hopefully this is an alternative solution to bring advanced therapies to Swedish patients.
