MiNA Therapeutics, the pioneer in RNA activation therapeutics, today announced the presentation of data supporting the on-target mechanism of action of drug candidate MTL-CEBPA. MTL-CEBPA is the first development candidate to emerge from MiNA’s RNA activation platform and is currently being evaluated in a Phase I clinical study in patients with liver cancer.
The data were presented at the 2016 Annual Meeting of the Oligonucleotide Therapeutics Society on September 26 in Montreal, Canada, in a poster titled “Development and mechanism of a small activating RNA targeting CEBPA, a novel therapeutic in clinical trials for patients with liver cancer”.
“Through a range of methods MTL-CEBPA has been validated to up-regulate the CEBP-α protein through an on-target and highly specific mechanism of transcriptional activation” commented Robert Habib, CEO of MiNA Therapeutics. “This data supports the potential of our RNA activation platform to up-regulate therapeutically ‘undruggable’ proteins in a highly specific manner.”
MTL-CEBPA is a SMARTICLES® liposomal formulation of CEBPA-51, a small activating RNA targeting the CEBPA gene. In the experiments covered by the presentation, CEBPA-51 was shown in cell lines to transcriptionally activate expression of CEBPA gene resulting in increased levels of CEBPA mRNA as well as CEBP-α protein. Mutations and modifications to the sequence of CEBPA-51 demonstrated this mechanism to be sequence specific as well as strand specific. Incorporation of 2’O-Me modifications in CEBPA-51 was shown to abrogate immune stimulation without loss of on-target activity. In addition, CEBPA-51 was shown to co-localise with, and require for activity, Argonaute 2 – an enzyme involved in a cell’s innate regulation of gene expression.
The poster presented at the Oligonucleotide Therapeutics Society Annual Meeting is available on the Company’s website in the publication section under “Media”.
MTL-CEBPA consists of a double stranded RNA formulated into a SMARTICLES® liposomal nanoparticle and is designed to activate the CEBPA gene. By restoring CEBPA expression to normal levels, MTL-CEBPA has been demonstrated to attenuate or reverse liver disease in a range of pre-clinical studies including models of liver cancer, liver cirrhosis, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). MTL-CEBPA is currently under evaluation in OUTREACH, a first-in-human Phase I clinical study in patients with severe liver cancer. The multi-centre Phase I study will assess the safety and tolerability of MTL-CEBPA in patients with advanced primary or metastatic liver cancer who are ineligible or resistant to standard therapies.
