Opsona Therapeutics Ltd. to present results on Tomaralimab study at the 60thAnnual Meeting of the American Society of Hematology (ASH)

25 October 2018, Dublin, Ireland – Opsona Therapeutics Ltd (‘Opsona’), today announces that it will give an oral presentation on results from its ongoing prospective, open label Phase I/II study being conducted with Tomaralimab (OPN-305), its novel proprietary humanized IgG4 monoclonal antibody (MAb) against Toll-Like Receptor 2 (TLR2), in second and third-line lower (Low and intermediate-1) risk myelodysplastic syndrome (MDS). The presentation will take place on Dec 03rd 2018 at the 60th Annual Meeting of the American Society of Hematology (ASH) in San Diego. 

The study in transfusion-dependent patients with lower risk MDS who have failed hypomethylating agents is ongoing in collaboration with the MD Anderson Cancer Center in Houston, Moffitt Cancer Center in Florida, Weill Cornell in New York and Montefiore in the Bronx USA. 

The lead principal investigator Professor Guillermo Garcia-Manero will present the data at ASH and commenting on today’s announcement said “Tomaralimab therapy presents a potential safe and efficacious therapeutic option for heavily pre-treated low risk patients that have failed HMA therapy.” 

Myelodysplastic syndromes are a complex and heterogeneous group of bone marrow failure disorders characterized by ineffective hematopoiesis and poor prognosis. Transfusion dependent patients who have failed on HMA have a worse prognosis in terms of survival. The best standard of care for patients in the USA who have failed on HMA is repeated red blood cell transfusions which are associated with reduced Quality of Life outcomes. 

There is an urgent need for the development of novel therapies in the treatment of MDS in patients who have exhausted other therapies and which can eliminate the need for red blood cell transfusions, delay progression, improve patient survival and overall quality of life. 

Details of the presentation are as follows:
