About L-DOS47

L-DOS47 is the Company's first drug candidate under development based upon its DOS47 technology. L-DOS47 is a therapeutic immunoconjugate which combines Helix's proprietary DOS47 technology with a highly specialized camelid-derived single domain antibody designed to identify a unique CEACAM6 antigenic site predominantly associated with non-small cell lung cancer ("NSCLC") cells. DOS47 is designed to function by leveraging a natural process in the body called the urea cycle, to produce an anti-cancer effect. It is based upon a naturally occurring enzyme called urease that essentially reverses the urea cycle by breaking down urea into metabolites that include ammonia and hydroxyl ions. By breaking down urea at the site of cancerous tissues in the body, L-DOS47 is believed to modify the microenvironmental conditions of cancer cells in a manner that leads to their death. Among these theorized effects, L-DOS47 is believed to stimulate an increase in the pH of the microenvironment surrounding the cancerous cells, effectively reversing the acidic extra-cellular conditions that are known to be necessary for cancer cell survival. As well, the local production of ammonia at the site of cancerous tissues is thought to readily diffuse into the cancer cells to exert a potent cytotoxic effect by interfering with their critical metabolic functions.
