iNtRON identifies Prophage and Jamphage in the Pancreatic cancer related Microbiome

It was confirmed the presence of Prophage and Jamphage in the Alkalihalobacillus clausii

Prophage and Jamphage are expected to play a substantial role in bacterial survival and immune regulation in the body.

BOSTON and SEOUL,South Korea,May 30,2023 -- iNtRON Biotechnology ("iNtRON",www.intodeworld.com) has announced today the identification of Prophage and (non-) ORF-Jamphage from the microbiome frequently observed in long-term Pancreatic cancer survivors. This significant identification was achieved as part of ongoing PHAGERIARUS® development project conducted by New Drug Part of the company.

PHAGERIARUS® development project is focused on acquiring bacteriophage-derived proteins that can serve as Immune Regulators (IR). The ultimate goal is to develop phage-based immunotherapeutics capable of treating a range of immune disorders including cancer. The project is built on the research that bacteriophages not only act as essential factors for the survival and growth of bacteria,but also play a role in regulating the immune system. In addition to the ongoing efforts to secure diverse IR candidates,the project involves with comprehensive genomic and functional analysis of disease-associated microbiomes and bacteriophages. Additionally,the project aims to elucidate the Mode of Action (MoA) of IR-related proteins derived from bacteriophages.

iNtRON has been conducting researches mainly focused on lytic bacteriophages for securing IR candidates and obtaining Open Reading Frames (ORFs) within its genomes. However,it has been discovered that a significant portion of bacteria residing in the body carry lysogenic bacteriophages (Prophage/Jamphage) in its genome. Recognizing the potential substantial role of these lysogenic phages in inducing immune responses within the body,iNtRON is actively securing genetic resources derived from Prophage/Jamphage.

The primary focus of the company lies in Colorectal cancer and Pancreatic cancer. It has been reported that patients diagnosed with Pancreatic cancer exhibit a specific microbiome in the organ,which is more prevalent in the long-term survivors (LTS) group (survival period longer than 10 years) compared to the short-term survivors (STS) group (survival period less than 5 years,median: 1.6 years). Alkalihalobacillus clausii has been identified as a representative microbiome,and iNtRON has obtained the strain and confirmed the presence of Prophage and Jamphage through the genomic analysis.

As previously reported,the bacterial strains are believed to affect the survival rate of Pancreatic cancer. iNtRON specifically anticipates that Prophage and (non-) ORF-Jamphage present in the strains play a significant role as IR modulating the immune system. According to the analysis results,a total of 7 strains have been identified to contain 4 types of Prophage,3 types of ORF-Jamphage,and 12 types of Non-ORF-Jamphage,comprising a total of 531 ORFs. In conclusion,these Prophage and (non-) ORF-Jamphage-derived ORFs are considered potential IR candidates.

The secured microbiomes are expected to reduce the occurrence and recurrence of Pancreatic cancer and through a certain mechanism,promote the patient's immune system for the long-term survival. The actual functioning of the bacterial strains is expected to be mediated by Prophage and Jamphage,and iNtRON is conducting subsequent development based on the expectation.

Dr. SON,Ji-soo,the head of the BD Department said that "We are currently securing a number of IR candidate materials to verify the performance and efficacy to be applied in the development of PHAGERIARUS®. While initially focusing on Colorectal cancer and Pancreatic cancer,considering their prevalence and intractability,we plan to gradually expand our research scope to include the microbiome related to neurological diseases such as Alzheimer's disease and Parkinson's disease." He added,"Our bacteriophage-based New Drug is undoubtedly a 'First-in-Concept' drug that can effectively control various immune-related diseases. Therefore,we will continue to actively pursue the PHAGERIARUS® development project,which involves the analysis and acquisition of Prophage and Jamphage from microbiomes specifically found in patients with various diseases,and then elucidates the functions of each component."

Mr. YOON,Kyung-won,CEO of iNtRON said that "While most of the existing bacteriophage research and development is focused on bacterial infectious diseases,iNtRON is expanding the application of bacteriophages to include antiviral drug development and also immune-related drug development." He further emphasized,"This expansion will clearly lead us to significant achievements in 'First-in-Class' and 'First-in-Concept' drug developments. We will dedicate our efforts in establishing collaborations and building technological networks with overseas companies in relation to these endeavors."
