  1. About i-DPS and its development programs

Bifidobacterium is obligatory anaerobe which exists as enteroflora in the human body, and known as nonpathogenic bacteria. Solid cancers have immature vascular constructs and their interstitial tumors are in the state of hypoxia. The company aims to leverage the recombinant Bifidobacterium technology to create a new class of anti-cancer drugs. The technology offers broad potential of being more effective to solid tumors and generates oncology drugs with less risks of adverse events than conventional anti-cancer drugs.


The leading product developed using i-DPS technology, APS001F, a recombinant Bifidobacterium to express Cytosine Deaminase which converts a prodrug, 5-FC, to an anti-cancer drug, 5-FU, is under a phase 1 clinical trial in the U.S.
