Xylonix Reveals New Drug Compound for Combating Cancer and Abnormal Macrophages

SINGAPORE,March 22,2021 -- Xylonix,a Singapore-based biotech company,has developed a new immunity drug (010DS-Zn) that demonstrates potential for treating a variety of solid cancers and COVID-19's post-recovery complications,which include heart damage,diabetes and multi-system inflammatory syndrome in children (MIS-C). This research was recently submitted as a preprint publication on bioRxiv.org (https://www.biorxiv.org/content/10.1101/2021.03.18.433812v1).

Aggressive solid cancers have been known to manipulate immunity for its advancements in several ways. One way is the enrichment of an immunity subset called M2-like macrophages (M2),which is associated in cancer metastasis,relapse,and treatment resistance. Recent studies showed that COVID-19 infection resulted in similar immune pathologies to solid cancers – increased M2 activity and suppressed CD4 and CD8 T-cells[1] activity.

Xylonix demonstrated that its drug compound 010DS-Znmarkedly reduced M2 population,while simultaneously boosting anti-cancer CD4 and CD8 T cells. This resulted in tumour suppression in animal studies. It also demonstrated consistent anti-cancer activity in 53 human patient-derived cancers testedex vivo.

"Today's cancer immunotherapy combinations can cost upwards of $200,000/year (1),but beneficial responses in patients happen at 15% chance-at-random (2). We developed 010DS-Zn as a widely applicable immunotherapy to significantly increase these odds. As of today,we are concerned about the 120 million and more people (3)with COVID-19 infection history who may suffer from long term recovery complications. We have manufactured sufficient quantity of 010DS-Zn to be used for multiple collaborations,and we are looking for capable partners to work with us on further studies on 010DS-Zn's effect on human tumours and COVID-19 complications," said Dr Fred Chung,Chief Scientific Officer and Co-founder Xylonix.

[1] CD4 and CD8 T-cells are specific types of lymphocytes that play a central role in the immune system,helping the body fight off infections and tumors.
