Omega Therapeutics Presents New Preclinical Data Supporting the First Epigenomic Controller, OTX-2002, as a Potential Therapeutic Approach in Hepatocellular Carcinoma at the ESMO 2022 World Congress on Gastrointestinal Cancer
Omega Therapeutics (Nasdaq: OMGA) has presented promising preclinical data on OTX-2002, an epigenomic controller targeting the MYC oncogene, at the ESMO 2022 World Congress. The data showed significant in vivo efficacy in xenograft tumor models and successful downregulation of MYC expression in non-human primates. OTX-2002 demonstrated potential as a monotherapy and in combination with immune checkpoint inhibitors. An Investigational New Drug (IND) application has been filed with the FDA to advance OTX-2002 into clinical trials for hepatocellular carcinoma (HCC).

- Potential for OTX-2002 as a combination therapy with immune checkpoint inhibitors.
- IND filed to advance OTX-2002 into clinical trials.
- None.
- Treatment with epigenomic controller, OTX-2002, resulted in robust in vivo efficacy in xenograft tumor models
- OTX-2002 successfully achieved pre-transcriptional downregulation of hepatocyte MYC gene expression in non-human primates
- Clinical potential of OTX-2002 as a monotherapy or in combination with existing standard-of-care therapies, including immune checkpoint inhibitors
- IND filed by the company to advance OTX-2002 into the clinic
CAMBRIDGE, Mass., June 30, 2022 /PRNewswire/ -- Omega Therapeutics, Inc. (Nasdaq: OMGA) (Omega), a development-stage biotechnology company pioneering the first systematic approach to use mRNA therapeutics as a new class of programmable epigenetic medicines by leveraging its OMEGA Epigenomic Programming™ platform, announces the presentation of new preclinical data on its lead product candidate, OTX-2002, to regulate expression of the c-Myc (MYC) oncogene through epigenetic modulation in multiple models of hepatocellular carcinoma (HCC) in a poster presentation at the European Society of Medical Oncology (ESMO) 2022 World Congress on Gastrointestinal (GI) Cancer, taking place in Barcelona, Spain, June 29 – July 2, 2022.
"We are proud to present these new data and add to the wealth of evidence supporting the potential of OTX-2002 as a new treatment option for patients suffering from HCC," said Thomas McCauley, Ph.D., Omega's Chief Scientific Officer. "In addition to providing strong evidence of OTX-2002's activity in the most translationally relevant species to human, non-human primates, the data support its potential as a monotherapy as well as its ability to synergize with existing treatment options. We believe epigenomic programming offers a promising avenue to precisely target previously undruggable genes, like MYC, that overcomes the compensatory mechanisms that have hindered previous modalities. We have recently filed an IND with the FDA for OTX-2002 and look forward to continuing to advance towards the clinic in service of patients."
- In non-human primates, treatment with OTX-2002 resulted in durable reduction of MYC mRNA levels in liver consistent with previous in vitro and in vivo studies
- OTX-2002 treatment decreased MYC mRNA and protein levels and cell viability in multiple HCC cell lines, while sparing normal cells
- OTX-2002 significantly reduced tumor growth in HCC xenografts models
- OTX-2002 treatment is associated with decreased expression of the immune checkpoint factor PD-L1 in HCC cells, suggesting a potential role for combination therapy with immune checkpoint inhibitors
- Combining OTX-2002 with existing standard of care therapies for HCC resulted in further reduction of cell viability and tumor burden in both in vitro and in vivo HCC models, respectively
- OTX-2002 treatment demonstrated synergistic activity with AKT inhibition in HCC cells, highlighting additional possible combination approaches

OTX-2002 is a first-in-class Omega Epigenomic Controller™ in development for the treatment of HCC. OTX-2002 is an mRNA therapeutic delivered via lipid nanoparticles (LNPs) and is designed to downregulate MYC expression pre-transcriptionally through epigenetic modulation while potentially overcoming MYC autoregulation. The MYC oncogene is associated with aggressive disease in up to ~
Omega Therapeutics, founded by Flagship Pioneering, is a development-stage biotechnology company pioneering the first systematic approach to use mRNA therapeutics as a new class of programmable epigenetic medicines. The company's OMEGA Epigenomic Programming™ platform harnesses the power of epigenetics, the mechanism that controls gene expression and every aspect of an organism's life from cell genesis, growth, and differentiation to cell death. Using a suite of technologies, paired with Omega's process of systematic, rational, and integrative drug design, the deterministic OMEGA platform enables control of fundamental epigenetic processes to correct the root cause of disease by returning aberrant gene expression to a normal range without altering native nucleic acid sequences. Omega's modular and programmable mRNA medicines, Omega Epigenomic Controllers™, target specific epigenomic loci within insulated genomic domains, EpiZips™, from amongst thousands of unique, mapped, and validated genome-wide DNA-sequences, with high specificity to durably tune single or multiple genes to treat and cure diseases through Precision Genomic Control™. Omega is currently advancing a broad pipeline of development candidates spanning a range of disease areas, including oncology, regenerative medicine, multigenic diseases including immunology, and select monogenic diseases, including alopecia.
