Helix BioPharma Corp. Announces L-DOS47 Scientific Presentation to Be Made at the Second Annual IBC Conference on Analytical Technologies Biotherapeutic Development

AURORA, ON--(Marketwire - Mar 1, 2012) - Helix BioPharma Corp. (TSX: HBP) (NYSE Amex: HBP) (FRANKFURT: HBP), a biopharmaceutical company developing drug candidates for the prevention and treatment of cancer, today announced that an L-DOS47 scientific presentation will be made at the Second Annual IBC Conference on Analytical Technologies Biotherapeutic Development in San Diego, California, USA.

The presentation will highlight specific analytical control strategies that are unique to the development of L-DOS47 as well as some stability data on both the drug substance and the lyophilized drug product candidate. In particular, it is shown that representative lots of bulk drug substance can be stored for at least 18 months and lots of freeze-dried drug product can be stored for at least 21 months. Stability studies for these lots of drug substance and drug product are ongoing. The presentation will be made by KBI BioPharma Inc., which provides L-DOS47 analytical support services to Helix on a contract basis. The slide show portion of the presentation will be available on Helix's website for viewing (http://www.helixbiopharma.com). See the IBC website (http://www.ibclifesciences.com/Analytical/overview.xml) for conference details.

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 DOS47 technology with a highly specialized camelid-derived single domain antibody designed to identify a unique CEACAM6 antigenic site predominantly associated with NSCLC cells. As previously announced, the National Research Council of Canada has granted Helix the right to use this antibody in combination with Helix's DOS47 technology under a worldwide exclusive license agreement. L-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, the Company believes that L-DOS47 will modify the micro-environmental conditions of cancer cells in a manner that leads to their death. Among these theorized effects, Helix believes that L-DOS47 will 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. Helix also believes that the local production of ammonia at the site of cancerous tissues will readily diffuse into the cancer cells to exert a potent cytotoxic effect by interfering with their critical metabolic functions.
