Regulus Presents Preclinical Survival Data Highlighting Potential of Novel Treatment for Glioblastoma Multiforme

LA JOLLA, Calif., Nov. 19, 2018 /PRNewswire/ -- Regulus Therapeutics Inc. (NASDAQ: RGLS), a biopharmaceutical company focused on the discovery and development of innovative medicines targeting microRNAs, today announced that it presented new data on the therapeutic potential of its lead anti-miR candidate for the treatment of glioblastoma multiforme (GBM), at the Society for Neuro-Oncology meeting held November 15-18, 2018 in New Orleans, LA.  The Company presented data highlighting the following:

• Confirmation of the differential upregulation of miR-10b in GBM tumor cells compared to normal brain tissue and a panel of other normal and malignant cell types.
• Identification of highly potent and specific anti-miR-10b oligonucleotide compounds that inhibited the growth of human GBM cell lines in vitro and in vivo.
• Demonstration of significant synergy benefit with the Company's lead anti-miR-10b compound. Results showed efficacy as monotherapy (18% increase in median survival vs. control) comparable to standard of care temozolomide (27% increase in median survival) and synergy in combination with temozolomide ( >150% increased median survival; p = 0.0001) in an orthotopic tumor model in which human GBM cells were surgically implanted into mouse brains. Further details are available in the poster provided on Regulus' website.

"These results provide strong evidence that targeting miR-10b may provide therapeutic benefit in patients with GBM and supports the continued advancement of our program to address this cancer which has no highly effective therapy," said Dr. Timothy Wright, Regulus' Chief R&D Officer.  "Regulus anticipates selection of a clinical candidate by year-end."
