[6-K] BioLineRx Ltd. Current Report (Foreign Issuer)

Rhea-AI Filing Summary

BioLineRx Ltd. has begun a first‑in‑human Phase 1/2a study of GLIX1, an oral, first‑in‑class TET2 activator, for recurrent and progressive glioblastoma and other high‑grade glioma. GLIX1 aims to selectively disrupt DNA damage repair in cancer cells while sparing healthy tissue.

The Phase 1 portion is expected to enroll up to 30 patients to determine a maximum tolerated or recommended dose based on safety, pharmacokinetics/pharmacodynamics and early efficacy, with initial data anticipated in the first half of 2027. The Phase 2a expansion will test GLIX1 in multiple tumor cohorts and combinations, including with standard treatments such as PARP inhibitors.

The trial is led by world‑recognized GBM investigators at NYU Langone Health, Northwestern University and Moffitt Cancer Center, under a collaboration with Hemispherian AS. BioLineRx also highlights its approved product APHEXDA for stem cell mobilization in multiple myeloma and an ongoing Phase 2b study of motixafortide in metastatic pancreatic cancer.

Insights

Biotech clinical development analyst

Early human testing of GLIX1 in glioblastoma begins, adding a new oncology program to BioLineRx’s pipeline.

BioLineRx is advancing GLIX1, a first‑in‑class oral TET2 activator, into a Phase 1/2a trial for recurrent and progressive glioblastoma and other high‑grade glioma. The study targets DNA damage repair pathways, supported by preclinical data showing blood‑brain barrier penetration, anti‑tumor activity and a favorable toxicology profile.

The Phase 1 segment will enroll up to 30 patients to establish a maximum tolerated or recommended dose from safety, PK/PD and preliminary efficacy readouts, with data anticipated in H1 2027. A Phase 2a expansion will explore additional glioblastoma settings and other cancers, including in combination with existing treatments such as PARP inhibitors, to generate early efficacy and dose optimization signals.

Academic leadership from NYU Langone Health, Northwestern University and Moffitt Cancer Center, together with a collaboration with Hemispherian AS, provides external validation but does not yet change the overall risk profile inherent to early‑stage oncology assets. The company also continues to commercialize APHEXDA and develop motixafortide in a Phase 2b metastatic pancreatic cancer study, diversifying its oncology portfolio.

For Immediate Release

BioLineRx Announces Initiation of Phase 1/2a Study of GLIX1 for the Treatment of

Glioblastoma (GBM)

GLIX1, a TET2 activator, is a first-in-class, oral, small molecule targeting DNA damage response

in glioblastoma and other cancers

GLIX1 has demonstrated potent anti-tumor activity in multiple GBM models, excellent blood-brain

barrier penetration and a favorable safety profile in preclinical toxicology studies

Study is being conducted by world-leading glioblastoma investigators, led by Dr. Roger Stupp

TEL AVIV, Israel, March 26, 2026 – BioLineRx Ltd. (NASDAQ/TASE: BLRX), a clinical development stage biopharmaceutical company pursuing life-changing therapies in oncology and rare diseases, today announced the initiation of a first-in-human, Phase 1/2a study of GLIX1 for the treatment of recurrent and progressive GBM and other high-grade glioma (NCT07464925).

GLIX1 is an oral small molecule with a novel mechanism of action applicable to a broad range of cancers. By restoring TET2 activity, GLIX1 selectively targets DNA damage repair in cancer cells only. GBM was selected as the first indication for GLIX1 due to the low level of TET2 activity in this aggressive brain cancer, for which there remains a high unmet medical need for novel and more effective treatments. In extensive preclinical studies, including in-vivo GBM models, GLIX1 demonstrated potent anti-tumor activity and excellent blood-brain-barrier penetration, combined with a favorable safety profile in toxicology studies.

Three renowned academic centers will ultimately participate in this clinical trial. The first center ready to start enrolling patients is NYU Langone Health, led by Dr. Alexandra Miller. This will be followed by Northwestern University, led by Dr. Roger Stupp and Dr. Ditte Primdahl, and by Moffit Cancer Center, led by Dr. Patrick Grogan.

“The initiation of this study represents the culmination of many months of tireless work on behalf of our team and the team of our collaboration partner, Hemispherian AS, as well as a pivotal moment in our mission to identify and advance innovative drugs to treat diseases with significant unmet needs,” stated Philip Serlin, Chief Executive Officer of BioLineRx. “GLIX1 has a very compelling profile supporting this Phase 1/2a study and, to that end, we look forward to initial data in the first half of 2027.”

Dr. Alexandra Miller, Chief of Neuro-Oncology and Co-Director of the Brain and Spine Tumor Center at the Perlmutter Cancer Center, NYU Langone Health, stated, “I am pleased to be the first investigator able to enroll patients into this critical study, which brings new hope to patients who are in desperate need of innovative and novel treatment options.”

Dr. Roger Stupp, Medical Director of the Malnati Brain Tumor Institute at Northwestern University in Chicago, and lead investigator of the study, added, “GLIX1 is a promising innovative molecule with impressive pre-clinical data, and I could not be more excited to participate in this study. The protocol will rigorously assess the safety of an agent with an entirely novel mechanism of action, with the potential to ultimately integrate well and synergize with the current treatments. We urgently need breakthrough innovations for our patients suffering from glioblastoma, one of the most aggressive and difficult malignancies to treat.”

Phase 1/2a clinical trial design (NCT07464925)

The Phase 1 part of the trial is expected to recruit up to 30 patients with recurrent and progressive GBM and other high-grade glioma. The objective is to establish a maximum tolerated dose (MTD) and/or a recommended dose based on safety, PK/PD and preliminary efficacy. Data from the Phase 1 part of the trial are anticipated in H1 2027.

The Phase 2a expansion part of the trial is planned to include various population cohorts, including GBM (newly diagnosed and/or recurrent), as well as additional cancers with/without standard of care (e.g., PARP inhibitors). These cohorts are expected to identify preliminary efficacy, PD assessments and dose optimization data, serving as the basis for a rapid and effective advanced clinical development plan.
