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."

Ayrmid will add APHEXDA to its commercial portfolio, which also includes Gamida Cell’s OMISIRGE, the first and only FDA-approved, nicotinamide (NAM)-modified cell therapy for patients with hematologic malignancies in need of a stem cell transplant. As part of this transaction, Ayrmid expects to transition certain members of BioLineRx’s U.S.-based commercial organization, who will support both stem cell transplant drugs.

Through this transaction, BioLineRx will significantly reduce its long-term debt and operational expenses, which will be reviewed in detail during the company’s upcoming Q3 results conference call and webcast.

BioLineRx also entered into a share purchase agreement for a $9 million equity investment from certain funds managed by Highbridge Capital Management, LLC. This investment and the combined future potential commercial milestones from licensing agreements with Ayrmid and Gloria Biosciences, as well as royalties on net sales, are expected to provide a strong foundation for BioLineRx to advance its pipeline and identify potential additional assets for development. The equity investment is expected to close today, November 21, 2024, subject to the satisfaction of customary closing conditions.

BioLineRx will continue the development of motixafortide for pancreatic ductal adenocarcinoma (PDAC) through meaningful collaborations, including an active Phase 2b PDAC study led by Columbia University, and supported equally by BioLineRx and Regeneron, as well as a planned Phase 2b PDAC study in China led by Gloria Biosciences.

"Since APHEXDA’s launch last year, patients and transplant centers continue to see the tremendous benefits it can provide, and I could not be prouder of our commercial organization that has proven its value," stated Philip Serlin, Chief Executive Officer of BioLineRx. "Our agreement with Ayrmid, and their vision of creating a strong commercial transplant portfolio, makes them the ideal partner to realize APHEXDA’s full commercial potential. BioLineRx will now leverage its proven expertise in drug development, with a continued focus on oncology and rare diseases. This new path forward aligns with our core strengths and allows us the opportunity to create enduring value for all stakeholders."

Dr. Joe Wiley, Chief Executive Officer of Ayrmid Ltd, added, "APHEXDA represents a significant advancement in improving the lives of multiple myeloma patients as they progress along the stem cell transplant journey. APHEXDA complements our existing portfolio by supporting OMISIRGE’s growth, doubling our transplant portfolio, and enhancing the capabilities Gamida Cell has already established in cell therapy. Our growing momentum positions us well for continued expansion in the U.S. and beyond, marking a key step in our journey as we continue to build on our success, strengthen our commitment to the transplant community, and execute our long-term strategy."

The equity investment offering is being made by BioLineRx pursuant to its shelf registration statement on Form F-3 (File No. 333-276323) previously filed with the Securities and Exchange Commission (the "SEC") and declared effective by the SEC on January 5, 2024, and only by means of a prospectus and prospectus supplement.

A major site for the Phase 1 trial would be the MD Anderson Cancer Center in Houston, internationally recognized for its expertise in treatment of ACC. To initiate and fully comply with the CPRIT grant, Orphagen will raise additional matching funds and move its headquarters to Texas in 2025.

Scott Thacher, Orphagen’s CEO and founder, stated, "This is an important step forward for our programs. OR-449 is the first of our internal programs that is on the path to a Phase 1 trial."

"Further OR-449 represents a significant opportunity for improved therapy of ACC patients, whose options for medical therapy are limited. The target of OR-449 is the orphan nuclear receptor SF-1, now recognized as a potential driver of ACC."

Orphagen Pharmaceuticals is a preclinical stage biopharmaceutical company focused on discovering and developing first-in-class therapeutics for cancer and inflammatory disease. Orphagen is a pioneer in the screening, discovery and development of ligands that modulate orphan or unexplored members of the nuclear receptor family. On a per target basis, the nuclear receptors are one of the most successful target classes known to the pharmaceutical industry.

Its first-in-class SF-1 antagonist (OR-449) has practically completed IND-enabling studies. Potential expansion indications for OR-449 include other cancers where SF-1 expression is highly elevated in such a way to suggest these depend on SF-1 activity for tumor growth.
