Scientists from the Medical University of Gdańsk, Poltreg S.A. and Technische Universität Dresden published the description of new generation of medicinal product containing antigen-specific T regulatory cells. The work: „Antigen-reactive regulatory T cells can be expanded in vitro with monocytes and anti-CD28 and anti-CD154 antibodies” can be read in the Cytotherapy – official journal of the International Society of Cell and Gene Therapy. The product is intended for the treatment of autoimmune diseases. The paper summarizes the research and patent claimed under the same title last year.
During 80th Scientific Sessions of the American Diabetes Association (12-16.06.2020) the scientists from STRATEGMED TREGS consortium and PolTREG company presented for the first time presumptive results of the phase II trial with T regulatory cells. From the tested approaches, the combined treatment with T regulatory cells and antiCD20 antibody proved to be the most promising. The patients treated with this combined scheme were in the clinical remission almost throughout entire 2-year-lasting follow-up, being administered with less than 0.5 units of insulin per kg body weight daily. At the same time, they were characterized by the best metabolic control with glycosylated haemoglobin HbA1c below 6.5%. The patients treated with this combined regimen achieved the longest insulin-independence which lasted as long as 18 months post-treatment.
Why does insulin trigger diabetes and what is the role of T regulatory cells?
Poltreg S.A. took a part in the resrearch just published in BMJ Open Diabetes Research and & Care. The work is a collaborative study of the medical universities from Gdańsk, Łódź, Katowice, University of Gdańsk, Regional Blood Bank and Poltreg S.A. in which the scientists proved that insulin is not only the hormone but also a dominant autoantigen involved in the development of type 1 diabetes
The links between insulin and the development of type 1 diabetes are known but the current work explains how insulin antigens trigger the progression of disease. Namely, the fragments of proinsulin sensitize and activate the immune system, which starts pathologic response against pancreatic islets secreting the hormone.
Why does not everybody develop the diabetes? It is because antigen-specific T regulatory cells, which are able to stop the activation of the immune system in the majority of people. The number of these cells is extremely low (below 0,01% in the peripheral blood) and only the recent laboratory tools used in the presented work were able to detect them.
The results of the work allowed the scientists from Poltreg S.A. and Medical University of Gdańsk to create the next generation of cellular drug which will be able to stop the activity of the immune system against insulin fragments and pancreatic islets.

The work was supported by the grants LIDER/160/L-6/14/NCBR/2015, STRATEGMED1/233368/1/NCBR/2014 and POIR.01.01.01-00-0769/15-03 from National Centre for Research and Development.
Final report from the study on safety of Tregs in multiple sclerosis
Medical University of Gdańsk together with Poltreg’s scientists submitted final report from the study: „Cell therapy of multiple sclerosis with ex vivo expanded CD4+CD25+CD127- T regulatory cells” to the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products. The results wil be published soon in the specialist journal.
Poltreg S.A. attended the meeting ‘Business in the Genes’ at the Warsaw Stock Exchange. We presented the progress of the company and reported accomplishment of phase II study in type 1 diabetes and phase I in multiple sclerosis. We also showed our current preparatory work on pivotal phase III study in type 1 diabetes in Eurpe and USA. We have also informed about hospital exemption procedure, which allows us to offer the therapy in the University Hospital in Gdańsk. The first patients were administered with the preparation already. Finally, we discussed current financial needs of the company and the progress of the fundraising to date.
