We are excited to welcome him to his new role as Omega’s Chief Executive Officer,” said Chris Schade, Chairman of the Board of Directors of Omega Therapeutics. “His deep scientific expertise and strong track record of driving strategic partnerships will be invaluable as we advance our pipeline of impactful programs and expand our business development efforts. On behalf of the entire board, I want to extend our sincere gratitude to Mahesh for his efforts in establishing a strong foundation for Omega and advancing epigenomic controllers to clinical proof-of-mechanism.” “I am excited to work with the board and our team to build on the progress Omega has made harnessing the power of epigenomic controllers. The compelling data that we have generated both clinically and pre-clinically gives us greater confidence in the potential of programmable epigenomic medicines to address a broad range of diseases,” said Kaan Certel, Ph.D., President and Chief Executive Officer of Omega Therapeutics. “The industry-first data from our recently completed, first-in-human clinical trial provide clear proof-of-mechanism, having demonstrated highly specific, on-target engagement with the intended epigenomic state change. We believe these data validate epigenomic controllers as a potential new class of medicines. In parallel, we have deepened our technical capabilities with a focus on upregulation and exquisite multiplexed control, which we believe may hold therapeutic advantages over existing modalities.” Dr. Certel continued, “Together with our new Chief Scientific Officer, Jennifer Nelson, Ph.D., we are focusing our pipeline on three programs with significant opportunities in obesity, regenerative medicine and metabolic indications that fully leverage our unique value proposition in epigenomic modulation. Going forward, we plan to focus our resources on these prioritized programs and on cultivating strategic partnerships to advance existing and new development candidates as a core component of our corporate strategy. We are actively engaged in ongoing dialogue with potential partners to further support and expand our pipeline in an accelerated and capital-efficient manner.” Prioritized Pipeline
Omega is prioritizing select preclinical programs in three areas where precision epigenomic control offers clear potential therapeutic advantages over existing modalities, including trans-differentiation for cellular reprogramming and durable upregulation of gene expression of intracellular proteins or secreted proteins where naturally occurring protein production may offer advantages over traditional biologics. Program advancement will be disciplined and data-driven to maximize shareholder value, capital efficiency and strategic partnering opportunities. Obesity
In collaboration with Novo Nordisk, Omega continues to advance the development of an epigenomic controller for obesity. This program leverages Omega’s platform capabilities in trans-differentiation to transition the epigenetic state of white adipose cells to metabolically active brown adipose cells, with the goal of enhancing metabolic activity as a part of a potential new treatment approach for obesity management. Regenerative Medicine HNF4A: Multiple liver diseases such as MASH (metabolic dysfunction-associated steatohepatitis) are characterized by fibrosis secondary to chronic inflammation. HNF4A is a nuclear receptor and master regulator of liver development and function. Upregulation of the HNF4A gene holds the potential to mitigate fibrosis and restore liver function. Omega has generated in vitro and in vivo data demonstrating the ability of epigenomic controllers to significantly upregulate HNF4A gene expression and reduce key measures of fibrosis. Metabolic FGF21: A hormone involved in multiple metabolic processes, FGF21 has been implicated in hyperlipidemia and obesity. Well established preclinical models have demonstrated clear translatability to clinical studies and provide an opportunity to rapidly advance candidates to clinical proof-of-concept studies. Upregulation of FGF21 through precision epigenomic control may offer a compelling approach to address multiple metabolic indications where upregulation of natural protein expression cannot be mimicked by existing modalities. Other Programs The Phase 1 MYCHELANGELO trial of OTX-2002 has been completed and the Company is engaged in discussions with potential partners to further advance clinical development into Phase 2 or may choose to resume development through internal efforts with additional funding.The OTX-2101 and CXCL1-8 programs have been deprioritized in order to focus resources and capital on the three selected programs described above. The Company is pursuing strategic partnership opportunities to advance these programs or may choose to resume development through internal efforts with additional funding. “Our prioritized pipeline leverages the differentiated capabilities of our platform and reflects the diverse potential applications of Omega’s technology. We are excited by the opportunity to demonstrate the power of precision epigenomic control in these select high-value programs and build on the clinical progress we have made,” said Jennifer Nelson, Ph.D., Chief Scientific Officer of Omega Therapeutics. “Our first-in-human study clearly demonstrated our ability to prospectively design an epigenomic controller capable of inducing prespecified changes in epigenetic signatures that alter gene expression with high specificity. Expanding on these results, we have an incredible opportunity to establish epigenomic controllers as a new class of medicines with unparalleled versatility.” Topline Data from Completed Phase 1 MYCHELANGELO™ Trial
The Phase 1 monotherapy dose escalation portion of MYCHELANGELO I was designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of OTX-2002 in patients with relapsed or refractory hepatocellular carcinoma (HCC) and other solid tumor types known for association with the MYC oncogene.
Twenty-four patients, including 19 with HCC, were enrolled across six dose cohorts (spanning 0.02 mg/kg to 0.3 mg/kg) and were treated with OTX-2002 intravenously once every two weeks. Topline data from the completed Phase 1 trial showed: Pharmacodynamics and pharmacokinetics: Highly specific on-target engagement with intended epigenetic changes at the target genomic loci, as evidenced by a robust increase in cell-free DNA MYC methylation signal following administration of study drug. The signal was dose dependent within the tolerated dose range. Pre-dose levels of MYC methylation were non-detectable. The increased methylation signal persisted throughout the two-week dosing interval and downregulation of MYC expression was observed.Predictable and consistent pharmacokinetics profile with rapid clearance, minimal variability observed within and between patients, and no accumulation observed with repeat administration. Safety and tolerability: At the recommended dose for expansion (0.12 mg/kg), OTX-2002 showed a favorable safety profile, with infusion-related reactions being the most common adverse event, generally consistent with the known profile of other FDA-approved LNP-delivered therapeutics. Preliminary clinical activity in HCC: The observed disease control rate (DCR) for response-evaluable HCC patients was 50%, with a best overall response of stable disease. This DCR is in-line with the historical benchmark range for completed Phase 1 trials for approved TKIs and PD-1 monotherapies in HCC (29-65%).
The Company plans to present the Phase 1 dataset at an upcoming scientific conference.
