The GLIX1 program is being conducted under a collaboration between BioLineRx and Hemispherian announced in September 2025. The patient was dosed at NYU Langone Health under the supervision of Dr. Alexandra Miller, Chief of Neuro-Oncology & Co-Director of Brain and Spine Tumor Center, Perlmutter Cancer Center. Northwestern University, led by lead investigators Dr. Roger Stupp and Dr. Ditte Primdahl, and Moffit Cancer Center, led by Dr. Patrick Grogan, will also be participating in the study.

GLIX1 is an oral, first-in-class, small molecule with a novel mechanism of action, designed to activate TET2 and drive tumor DNA damage. By restoring TET2 activity, GLIX1 induces DNA damage selectively in cancer cells, representing a differentiated approach to targeting the DNA damage response with potential applicability across a broad range of tumors. Glioblastoma was selected as the initial indication due to its highly suppressed TET2 activity and significant unmet medical need. GBM remains one of the most aggressive and treatment-resistant cancers, and there is an urgent need for breakthrough innovation and more effective treatment options.

In multiple pre-clinical models, including in-vivo GBM models, GLIX1 demonstrated potent anti-tumor activity, excellent blood-brain-barrier penetration, and a favorable safety profile.

"The dosing of the first patient in our Phase 1/2a study of GLIX1 is an important milestone for BioLineRx and, more importantly, for patients battling glioblastoma, a very challenging tumor where there has been very little innovation over the past 20 years," said Philip Serlin, Chief Executive Officer of BioLineRx. "We believe GLIX1 has the potential to offer a novel therapeutic approach in this cancer indication, as well as in multiple other cancer indications, where DNA damage repair is critical for cancer survival. We are excited to advance GLIX1 development into this first-in-human clinical trial and look forward to initial data in the first half of 2027."

Zeno Albisser, Chief Executive Officer of Hemispherian, added, "The initiation of patient dosing in this important study represents a watershed event for Hemispherian and GLIX1. This is the culmination of years of focused scientific and operational work, and an important step toward bringing a new therapeutic approach to patients with glioblastoma. We are encouraged by our preclinical data and look forward to generating initial clinical insights as the trial progresses."

Phase 1/2a clinical trial design (NCT07464925)

The Phase 1 part of the trial is a dose escalation part where patients receive GLIX1 daily as monotherapy. This part is expected to recruit up to 30 patients with recurrent and progressive GBM and other high-grade gliomas. 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 additional indications, including newly diagnosed GBM, as well as select cancers with/without standard of care (e.g., in combination with 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.
