"We are pleased to see the triple combination arm of our Phase 2a pancreatic study advance according to plan," stated Philip Serlin, Chief Executive Officer of BioLineRx. "This follows very promising initial results that were presented last month at the ESMO IO conference, demonstrating robust and durable responses to the triple combination treatment. As previously stated, we remain on track to announce progression-free and overall survival data from the triple combination arm in mid-2020."
A total of 40 patients diagnosed with unresectable stage IV metastatic pancreatic adenocarcinoma (PDAC), who have progressed following first-line gemcitabine-based therapy, were enrolled as planned in the triple combination arm focusing on second-line pancreatic cancer patients. Patients receive Motixafortide (BL-8040) monotherapy priming treatment for five days, followed by combination cycles of chemotherapy (Onivyde®/5-fluorouracil/leucovorin), KEYTRUDA® and Motixafortide until progression. The primary endpoint of the study is the objective response rate (ORR). Secondary endpoints include overall survival, progression free survival, and disease control rate.
Last month, the Company shared preliminary data at the ESMO IO conference showing that the triple combination demonstrated a 32% overall response rate (ORR) and a 77% disease control rate (DCR) out of 22 evaluable patients at the time. This compares favorably to the current chemotherapy standard-of-care treatment in second-line patients with ORR of 17% and DCR of 52%. In addition, the median duration of clinical benefit for all 17 patients with disease control (7 partial response and 10 stable disease patients) was 7.8 months, compared to approximately three months of response duration with other treatments for second-line pancreatic cancer.
The COMBAT/KEYNOTE-202 Study
The Phase 2a COMBAT/KEYNOTE-202 study was originally designed as an open-label, multicenter, single-arm trial to evaluate the safety and efficacy of the dual combination of Motixafortide and KEYTRUDA® (pembrolizumab), an anti-PD-1 therapy marketed by
About Motixafortide in Cancer Immunotherapy
Motixafortide is targeting CXCR4, a chemokine receptor and a well validated therapeutic target that is over-expressed in many human cancers including PDAC. CXCR4 plays a key role in tumor growth, invasion, angiogenesis, metastasis and therapeutic resistance, and CXCR4 overexpression has been shown to be correlated with poor prognosis.
Motixafortide is a short synthetic peptide used as a platform for cancer immunotherapy with unique features allowing it to function as a best-in-class antagonist of CXCR4. It shows high-affinity, long receptor occupancy and acts as an inverse agonist.
In a number of clinical and preclinical studies, Motixafortide has been shown to affect multiple modes of action in "cold" tumors, including immune cell trafficking, tumor infiltration by immune effector T cells, and reduction in immunosuppressive cells (such as MDSCs) within the tumor niche, turning "cold" tumors, such as pancreatic cancer, "hot" (i.e., sensitizing them to immune checkpoint inhibitors and chemotherapy).
The Company's lead program, Motixafortide, is a cancer therapy platform currently being evaluated in a Phase 2a study for the treatment of pancreatic cancer in combination with KEYTRUDA® and chemotherapy under a collaboration agreement with MSD. Motixafortide is also being evaluated in a Phase 2b study in consolidation AML and a Phase 3 study in stem cell mobilization for autologous bone-marrow transplantation. In addition, the Company has an ongoing collaboration agreement with Genentech, a member of the
BioLineRx is developing a second oncology program, AGI-134, an immunotherapy treatment for multiple solid tumors that is currently being investigated in a Phase 1/2a study.
