- AGI-134 on track to commence Phase 1/2a clinical study in H1 2018 -
TEL AVIV, Israel I January 23, 2018 I BioLineRx Ltd. (NASDAQ: BLRX) (TASE: BLRX) (TASE: BLRX.TA), a clinical-stage biopharmaceutical company focused on oncology and immunology, announced today that AGI-134, an immunotherapy compound in development for the treatment of multiple solid tumors, demonstrated successful results in two pre-clinical melanoma studies. Results of these studies will be presented as a poster titled "Intratumoral Administration of the Alpha-Gal Glycolipid AGI-134 to Induce Tumor Regression in a Mouse Model of Melanoma" (Abstract 68) on January 25, 2018 at the ASCO-SITC Clinical Immuno-Oncology Symposium, being held January 25-27, 2018, in San Francisco, CA.
The ability of intratumorally injected AGI-134 to induce regression of established primary tumors was assessed in two murine melanoma models. In the two models, there was complete tumor regression in 50% and 67%, respectively, of mice treated with AGI-134. Moreover, treatment with AGI-134 showed a beneficial effect on survival, compared to the control group. In addition, the results show that injection of AGI-134 into the tumors induces activation of the complement system, an important component of the innate immune system. Activation of the complement system within tumors by AGI-134 is predicted to destroy tumor cells and create a pro-inflammatory tumor microenvironment that attracts and activates other immune cells, ultimately resulting in adaptive anti-tumor immunity. Previous studies with intratumoral administration of AGI-134 to primary tumors had shown that AGI-134 protects mice from the development of distant, untreated tumors.
"We are pleased to report these encouraging results for our second lead oncology project at the upcoming ASCO-SITC conference," said Philip Serlin, Chief Executive Officer of BioLineRx. "Previous studies have demonstrated that intratumoral administration of AGI-134 induces a systemic anti-tumor response that protects mice from the development of distant tumors. These new studies now show direct regression of established primary tumors after injection with AGI-134, and that this regression is associated with activation of the innate immune system. These compelling pre-clinical data support investigating this approach in a Phase 1/2a study, and we are excited and on track to commence a first-in-man study with this promising novel oncology asset in patients with solid tumors in the first half of 2018."
AGI-134 is a synthetic alpha-Gal immunotherapy in development for solid tumors. AGI-134 harnesses the body's pre-existing, highly abundant anti-alpha-Gal antibodies to induce a systemic, specific anti-tumor response to the patient's own tumor neo-antigens. This response not only kills the tumor cells at the site of injection, but also brings about a durable, follow-on, anti-metastatic immune response. AGI-134 has completed numerous pre-clinical studies, demonstrating robust protection against the development of secondary tumors in a model of melanoma with a single dose only. Synergy has also been demonstrated in additional pre-clinical studies when combined with a PD-1 immune checkpoint inhibitor, offering the potential to broaden the utility of such immunotherapies, and improve the rate and duration of responses in multiple cancer types. AGI-134 was obtained by BioLineRx through the acquisition of Agalimmune Ltd.
BioLineRx is a clinical-stage biopharmaceutical company focused on oncology and immunology. The Company in-licenses novel compounds, develops them through pre-clinical and/or clinical stages, and then partners with pharmaceutical companies for advanced clinical development and/or commercialization.
BioLineRx's leading therapeutic candidates are: BL-8040, a cancer therapy platform, which has successfully completed a Phase 2a study for relapsed-refractory AML, is in the midst of a Phase 2b study as an AML consolidation treatment and has initiated a Phase 3 study in stem cell mobilization for autologous transplantation; and AGI-134, an immunotherapy treatment in development for multiple solid tumors, which is expected to initiate a first-in-man study in the first half of 2018. In addition, BioLineRx has a strategic collaboration with Novartis for the co-development of selected Israeli-sourced novel drug candidates; a collaboration agreement with MSD (tradename of Merck & Co., Inc.), on the basis of which the Company has initiated a Phase 2a study in pancreatic cancer using the combination of BL-8040 and MSD's KEYTRUDA; and a collaboration agreement with Genentech, a member of the Roche Group, to investigate the combination of BL-8040 and Genentech's atezolizumab in several Phase 1b/2 studies for multiple solid tumor indications and AML.
