November 11, 2024 – TheNewswire - Toronto, Ontario – Helix BioPharma Corp. (TSX: “HBP”, OTC PINK: “HBPCD”, FRANKFURT: “HBP0”) (“Helix” or the “Company), a clinical-stage biopharmaceutical company developing novel and unique therapies in the field of immuno-oncology, based on its proprietary technological CEACAM6 platform, DOS47, is pleased to announce that the Company attended the 15th World ADC San Diego from 4–7 November 2024, the world's leading and longest-standing forum on antibody-drug conjugates (ADCs).

World ADC San Diego is a comprehensive forum offering data-driven insights, case study presentations, and informative discussions led by forward-thinking ADC industry pioneers to address the challenges and opportunities of bringing ADCs from bench to bedside. Helix was represented this year by its Medical Adviser, Haematologist-Oncologist and seasoned Pharma executive, Thomas Mehrling, to keep abreast of emerging trends and breakthroughs in the field, as the Company advances its development of L-DOS47, Helix’ first-in-class enzyme-antibody-drug conjugate platform technology.  

L-DOS47 is a remarkable ADC in that it specifically binds to an antigen highly expressed on the cells of common, hard-to-treat cancers (CEACAM6, expressed on lung, colon and pancreatic cancer cells) and alkalizes the acidic tumor microenvironment (TME), unleashing the immune system’s anti-tumor defences and enhancing the therapeutic effects of anti-cancer agents.

Helix’ novel approach is currently advancing towards a Phase II study in patients with non-small cell lung cancer (NSCLC), though L-DOS47 is expected to have applications across diverse cancers and in combination with a broad range of anti-cancer agents (chemotherapy, immunotherapies and targeted small molecules), making L-DOS47 a platform technology. Helix is also considering broadening its pipeline with novel ADCs.

Thomas Mehrling, MD, PhD, Medical Adviser, said: “This year’s World ADC San Diego has reaffirmed that ADCs are among most exciting innovations in oncology at the moment, fuelling our conviction that Helix’ first-in-class TME-modifying technology is poised to turn the tables on hard-to-treat, prevalent cancers.”
