TEL AVIV, Israel, Sept. 28, 2023 /PRNewswire/ -- BioLineRx Ltd. (NASDAQ: BLRX) (TASE: BLRX), a commercial stage biopharmaceutical company pursuing life-changing therapies in oncology and rare diseases, today announced encouraging data from the single-arm pilot phase of the investigator-initiated CheMo4METPANC Phase 2 combination clinical trial evaluating the company's CXCR4 inhibitor motixafortide, the PD-1 inhibitor cemiplimab, and standard of care chemotherapies gemcitabine and nab-paclitaxel, versus gemcitabine and nab-paclitaxel alone, in first-line pancreatic cancer (PDAC).

The data were published in an online abstract as part of the American Association of Cancer Research (AACR) Special Conference on Pancreatic Cancer taking place in Boston, Massachusetts from September 27-30, 2023.  An oral presentation of the data will take place later today, September 28, 2023.

The pilot phase of the Phase 2 study enrolled 11 patients with metastatic pancreatic cancer.  As of May 2023, 6 patients (55%) experienced a partial response (PR) of which 4 (36%) were confirmed PRs with one patient experiencing resolution of the hepatic (liver) metastatic lesion. Three patients (27%) experienced stable disease, resulting in a disease control rate of 82%.  These findings compare favorably to historic partial response and disease control rates of 23% and 48%, respectively, reported with the current standard of care, the chemotherapy combination gemcitabine and nab-paclitaxel.

"These initial data from the pilot phase of this ongoing Phase 2 study give us hope that motixafortide could potentially serve as the backbone of a new treatment regimen for PDAC, which is among the most difficult cancers to treat," said Philip Serlin, Chief Executive Officer of BioLineRx Ltd.  "We are deeply committed to this important collaboration with Columbia University investigators and eagerly look forward to the data from the randomized phase of the trial."

Based on these pilot data, earlier this year, the CheMo4METPANC Phase 2 trial was amended to become a randomized study, with planned enrollment increasing from 30 to 102 patients.  The trial, sponsored by Columbia University, is the first large, multi-center, randomized study evaluating motixafortide with a PD-1 inhibitor and first-line PDAC chemotherapies.  A poster of the amended clinical trial design was presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, held June 2-6 in Chicago, Illinois (see abstract).

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and is expected to be the second leading cause of cancer-related death in the U.S. by 2023.  Because it is typically diagnosed at later stages, greater than 80 percent of pancreatic cancer is inoperable. Most pancreatic cancer is incurable and unfortunately newer immunotherapy approaches, while beneficial against other solid tumor types, have had limited efficacy in pancreatic cancer due to immunosuppressive pathways.

An earlier single-arm, Phase 2a clinical trial (COMBAT/KEYNOTE-202) and pre-clinical studies evaluating motixafortide in combination with PD-1 immunotherapies and chemotherapies in PDAC have been promising, suggesting the ability of motixafortide to support an immune response.

About CheMo4METPANC Phase 2 Clinical Trial

The multi-center CheMo4METPANC Phase 2 clinical trial is a randomized, investigator-initiated clinical trial in first line metastatic pancreatic cancer.  Sponsored by Columbia University, the study is evaluating the combination of CXCR4 inhibitor motixafortide, PD-1 inhibitor cemiplimab, and standard of care chemotherapies gemcitabine and nab-paclitaxel, versus gemcitabine and nab-paclitaxel, alone in 102 patients.  The trial's primary endpoint is progression free survival (PFS). Secondary objectives include safety, response rate, disease control rate, duration of clinical benefit and overall survival.

About Pancreatic Cancer

Pancreatic cancer has a low rate of early diagnosis and a poor prognosis.  In the United States in 2023, an estimated 64,000 adults will be diagnosed with the disease, which accounts for approximately 3% of all cancers in the U.S. and about 7% of all cancer deaths.  Worldwide, an estimated 496,000 people were diagnosed with the disease in 2020.  In the U.S., if the cancer is detected at an early stage when surgical removal of the tumor is possible, the 5-year relative survival rate is 44%. About 12% of people are initially diagnosed at this stage. If the cancer has spread to surrounding tissues or organs, the 5-year relative survival rate is 15%.  For the 52% of patients who are initially diagnosed with metastatic cancer, the 5-year relative survival rate is 3%.[i]  In particular, hepatic (liver) metastases are a critical risk factor driving poor prognoses for patients with metastatic PDAC. These data highlight the need for the development of new therapeutic options.

About Motixafortide in Cancer Immunotherapy

Motixafortide inhibits CXCR4, a chemokine receptor and a well validated therapeutic target that is over-expressed in many human cancers including pancreatic ductal adenocarcinoma (PDAC). Motixafortide leverages the expression of the CXCR4 receptor on different immune cells and potentiates the immune system against the tumor.  Among CXCR4-expressing immune cells, some exhibit anti-tumoral activity, such as effector T cells and some exhibit pro-tumoral activity and support tumor growth. By blocking the CXCR4 receptor, motixafortide was shown in a Phase 2 study in pancreatic cancer patients to enhance anti-tumoral activity and to ameliorate the pro-tumoral activities by modulating the effector/suppressor cell ratio towards a proinflammatory profile.
