U.S. Patent No. 11931422, entitled ‘Antibody-Urease Conjugates for Therapeutic Purposes’, relates to Helix’ first-in-class antibody-drug conjugate (ADC) platform, L-DOS47, and the optimization of conjugation ratios for a proprietary antibody that precisely binds to tumor cells expressing high levels of CEACAM6, conjugated to urease, an enzyme capable of alkalizing the acidic tumor microenvironment (TME).
CEACAM6 is a tumor antigen highly expressed on hard-to-treat, prevalent cancers where currently available treatments are not achieving meaningful enough clinical benefits for patients (including non-small cell lung cancer, pancreatic and colorectal cancers). Binding to CEACAM6, Helix’ LDOS47 converts urea into ammonia and alkalizes the TME, promoting tumor regression, restoring function to local immune cells (such as T cells) and opening the possibility to significantly enhance the treatment outcomes of available, established therapies, including chemotherapy, checkpoint inhibitors (immunotherapies) and targeted small molecules.
Jacek Antas, CEO of Helix, stated: "We are very pleased to receive the issuance of this patent in the U.S., an important oncology market with a significant need for novel treatment modalities and better clinical outcomes. The timing is also advantageous, considering our ongoing discussions about expanding our pipeline with synergistic oncology products."
