GBM remains one of the most aggressive and treatment-resistant cancers, urgently in need of breakthrough innovations and more effective treatment.
In a comprehensive pre-clinical program, orally administered GLIX1 demonstrated robust anti-tumor activity in orthotopic cell-derived xenograft (CDX) GBM models, as well as in a newly completed subcutaneous TMZ-resistant patient-derived xenograft (PDX) GBM model. In the three orthotopic CDX studies, significant tumor growth inhibition and survival benefit were observed following treatment with GLIX1 across all doses tested, with greater benefit at higher dose levels. In these models, mice treated with TMZ also showed significantly decreased tumor volume and survival benefit. Most notably, in the subcutaneous PDX model, GLIX1 demonstrated a robust anti-tumor effect while TMZ showed no effect.
"The compelling results from these studies, including the recently completed TMZ-resistant PDX model, are very exciting as they suggest that GLIX1 may bring hope to a broad range of patients with GBM," said Philip Serlin, Chief Executive Officer of BioLineRx. "In addition, the pre-clinical dose-response characterization adds important information for dose optimization in the Phase 2 part of the ongoing clinical study. 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."
BioLineRx and Hemispherian plan to present the data from these studies at one or more future medical conferences.
