LYON, France and CAMBRIDGE, Mass., March 11, 2019 (GLOBE NEWSWIRE) -- ERYTECH Pharma (Euronext Paris: ERYP - Nasdaq: ERYP), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating drug substances inside red blood cells, announced that an oral presentation entitled "Comprehensive proteomic profiling of erythrocytes following hypotonic dialysis-based drug encapsulation process" will be presented today at the 22nd meeting of the European Red Cell Research Society (ERCS) in Ascona, Switzerland. A poster highlighting the results of this work will also be presented at the ERCS Meeting and will be available on the Company`s website at www.erytech.com after March 11, 2019.
The lead investigational therapeutic produced using the Company`s ERYCAPS® encapsulation process, eryaspase, consisting of the enzyme L-asparaginase encapsulated inside donor-derived red blood cells, is currently being evaluated in the Phase 3 TRYbeCA-1 trial in metastatic pancreatic cancer1.
In an earlier 141 patient randomized Phase 2b trial of eryaspase in combination with chemotherapy for the treatment of second-line metastatic pancreatic cancer, significant improvements in overall survival and progression free survival were observed versus chemotherapy alone with no apparent increase in toxicity2.
The erythrocyte proteomic profiling study being presented at the meeting was performed with the participation of the 3P5 Proteomic Platform (at the Paris-Descartes University, France) specialized in high-performance mass spectrometry protein identification and microanalysis. With the exception of L-asparaginase, profiling analysis revealed no significant difference in the proteomic landscape when comparing packed RBCs, ERYCAPS®-processed RBCs without enzyme, and ERYCAPS®-processed RBCs encapsulating L-asparaginase.
These results confirm the notion that the ERYCAPS® process does not significantly alter the properties of RBCs and that apart from the encapsulated drug substance, RBC-based therapeutics produced using this process have similar characteristics to that of unprocessed packed RBCs.
Dr. Patrick Mayeux, an expert on RBCs proteome at the Cochin Institute, Paris, France and Scientific Director of the 3P5 Proteomic Platform, recently commented: "The constant advancement of proteomics technologies now allows a comprehensive analysis of the whole proteome of RBCs."
ERYTECH plans to advance candidates using the ERYCAPS® platform and to explore the field of RBC-based therapeutics, building on these proteomic results and future findings regarding RBC biology.
About ERYTECH: www.erytech.com
ERYTECH is a clinical-stage biopharmaceutical company developing innovative red blood cell-based therapeutics for cancer and orphan diseases. Leveraging its proprietary ERYCAPS platform, a novel technology to encapsulate drug substances inside red blood cells, ERYTECH is developing a pipeline of product candidates to address markets with high unmet medical needs.
ERYTECH`s primary focus is on the development of product candidates that target the altered metabolism of cancer cells by depriving them of amino acids necessary for their growth and survival. The Company`s lead product candidate, eryaspase, which consists of L-asparaginase encapsulated inside donor-derived red blood cells, targets the cancer cell`s altered asparagine and glutamine metabolism. Eryaspase is in Phase 3 clinical development for the treatment of second-line pancreatic cancer and in preparations to enter Phase 2 clinical development for the treatment of triple-negative breast cancer. ERYTECH`s next product candidate erymethionase, which consists of methionine-gamma-lyase encapsulated in red blood cells to target methionine-dependent cancers, has demonstrated promising preclinical results and is in preparations to enter Phase 1 clinical development.
ERYTECH is also exploring the use of its ERYCAPS platform for developing cancer immunotherapies (ERYMMUNE) and enzyme therapies (ERYZYME).
ERYTECH produces product candidates at its GMP-approved manufacturing site in Lyon, France, and at the American Red Cross in Philadelphia, USA. A large-scale GMP manufacturing facility is under construction in New Jersey, USA.
ERYTECH is listed on the Nasdaq Global Select Market in the United States (ERYP.PA) and on the Euronext regulated market in Paris (ISIN code: FR0011471135, ticker: ERYP). ERYTECH is part of the CAC Healthcare, CAC Pharma & Bio, CAC Mid & Small, CAC All Tradable, EnterNext PEA-PME 150 and Next Biotech indexes.
