Spherical Nucleic Acid Technology Shows Promising Results in Phase 0 Trial in Patients With Glioblastoma at Northwestern University
Exicure, Inc. (NASDAQ: XCUR) reported that Northwestern University researchers successfully utilized its gold-nanoparticle SNA technology in a first-in-human trial targeting glioblastoma (GBM). The phase 0 trial showed that intravenously administered siRNA-based SNAs can safely cross the blood-brain barrier and target the oncogene Bcl2L12. These findings, published in Science Translational Medicine, mark a significant milestone for Exicure’s technology in treating GBM. The company also plans to file an IND for Friedreich's ataxia by the end of 2021.
- Successful application of SNA technology in a first-in-human GBM trial.
- Published results in a reputable journal, enhancing credibility.
- Potential to cross the blood-brain barrier, indicating robust therapeutic capability.
- Plans to file an IND for Friedreich’s ataxia, expanding product pipeline.
- None.
Exicure, Inc. (NASDAQ: XCUR), a pioneer in gene regulatory and immunotherapeutic drugs utilizing spherical nucleic acid (SNA™) technology, is pleased to share that researchers at Northwestern University have utilized Exicure’s licensed first generation gold-nanoparticle SNA technology in an investigator-initiated trial for the treatment of glioblastoma (GBM), a deadly form of brain cancer.
The results were published in an article in Science Translational Medicine. https://stm.sciencemag.org/content/13/584/eabb3945 DOI:10.1126/scitranslmed.abb3945
The researchers that led the study, Drs. Priya Kumthekar and Alexander Stegh, conducted a single-arm, open-label phase 0 first-in-human clinical trial (NCT03020017) to determine safety, pharmacokinetics, intratumoral accumulation and gene-suppressive activity of systemically administered SNAs comprised of siRNA specific for the GBM oncogene Bcl2L12. Patients with recurrent GBM were treated with intravenous administration of siBcl2L12-SNAs (NU-0129).
The paper reports first-in-human evidence that siRNA-based SNAs can be administered intravenously, cross the blood-brain-barrier in glioblastoma patients, accumulate in GBM tumor cells, and engage with their target gene.
“We congratulate Drs. Kumthekar and Stegh on these results,” said Dr. David Giljohann, the CEO of Exicure. He added, “We are excited about the impact to patients and its implications in treating other diseases, as Exicure continues to build and grow our pipeline in neurological disorders.”
Exicure anticipates filing an IND for its lead program in Friedreich’s ataxia by the end of 2021.
About Glioblastoma
Glioblastoma (GBM) is the most common and most aggressive type of primary malignant tumor of the central nervous system. The global incidence of glioblastoma is less than 10 per 100,000 people. Standard treatment for patients with newly diagnosed glioblastoma can include surgery followed by radiation and chemotherapy, but treatment options are limited. The last investigational medicine to improve survival for patients with newly diagnosed glioblastoma was approved by the U.S. Food and Drug Administration in 2005. The five-year survival rate of patients with GBM is less than five percent.
About Friedreich’s Ataxia
Friedreich’s ataxia (FA) is the most commonly inherited ataxia, a degenerative neuromuscular disease leading to progressive loss of coordination, causing severe childhood disability and early mortality, in most cases before age 40. It is a monogenic disorder caused by mutations in the FXN gene resulting in reduced levels of frataxin protein. FA affects about 13,500 people in the US, Europe, Canada and Australia combined. There are currently no approved therapies for Friedreich’s ataxia patients.
About Exicure, Inc.
Exicure, Inc. is a clinical-stage biotechnology company developing therapeutics for neurology, immuno-oncology, inflammatory diseases and other genetic disorders based on our proprietary Spherical Nucleic Acid, or SNA technology. Exicure believes that its proprietary SNA architecture has distinct chemical and biological properties that may provide advantages over other nucleic acid therapeutics and may have therapeutic potential to target diseases not typically addressed with other nucleic acid therapeutics. Exicure is in preclinical development of XCUR-FXN a lipid-nanoparticle SNA–based therapeutic candidate, for the intrathecal treatment of Friedreich’s ataxia (FA). Exicure's therapeutic candidate cavrotolimod (AST-008) is in a Phase 1b/2 clinical trial in patients with advanced solid tumors. Exicure is based in Chicago, IL and in Cambridge, MA.
