IMUNON Announces Strategic Investment in Transomic Technologies

Investment of $375,000 with Senior Convertible Notes and Warrants; Strengthens Development Capabilities for IMUNON’s PLACCINE DNA Vaccine Platform

IMUNON’s Executive Chairman to join Transomic’s Board of Directors

LAWRENCEVILLE, N.J., Nov. 17, 2022 (GLOBE NEWSWIRE) — IMUNON, Inc. (NASDAQ: IMNN), a clinical-stage company focused on DNA-based immunotherapy and next-generation vaccines, today announced a $375,000 investment in Transomic Technologies, a private company offering a comprehensive array of CRISPR, RNAi and gene expression tools and services.

The Company has partnered with Transomic to utilize their custom vector construction services to continue to generate plasmids that are being developed and evaluated by IMUNON as part of their DNA vaccine program. As a condition of the investment, Michael H. Tardugno, IMUNON’s executive chairman, will join the Transomic board of directors.

“Given our continued progress with the PLACCINE DNA vaccine development program, we have made the strategic decision to continue to support Transomic Technologies with this investment,” said Corinne Le Goff, president and chief executive officer of IMUNON. “We have been utilizing Transomic’s custom vector construction and design services, and we are very pleased with the strength and flexibility of their platform.”

“We recently highlighted initial pre-clinical proof-of-concept data of our PLACCINE modality in a SARS-CoV-2 model, demonstrating the versatility of this technology to allow for the rapid design of multi-cistronic vectors expressing multiple pathogen antigens in one vaccine,” she added. “Transomic’s custom vector construction technology enables us to swiftly construct vaccines against newer variants in weeks, providing an important medical and commercial advantage.”

Blake Simmons, CEO of Transomic Technologies, said, “We are pleased to collaborate with the team at IMUNON in their pursuit of next-generation vaccines. Their PLACCINE DNA vaccine program is very promising, and we are hopeful that our services will help to unlock its potential. We look forward to continued participation in IMUNON’s research and development efforts and welcome our deepening partnership.”

About the PLACCINE Modality

PLACCINE, part of IMUNON’s proprietary nucleic acid technology with synthetic delivery systems platform, is the subject of multiple patent applications that cover a broad range of next-generation nucleic acid vaccines. An adaptation of the Company’s TheraPlas technology for therapeutic proteins, PLACCINE is a modality for prophylactic vaccines characterized by a single nucleic acid vector with multiple coding regions. The vaccine vector is designed to express multiple pathogen antigens along with the option to include a potent immune modifier. PLACCINE has potential to be easily modified to create vaccines against a multitude of infectious diseases, with benefits including:

  • Durability of protection – Durable antigen expression induces robust immunological response
  • Breadth of protection – Multi-cistronic vectors increase the breadth of immune response and allows for combination vaccines
  • Transmission advantage – DNA has a greater capability to induce T-cell activity against infected cells; option for co-expression of potent immune modifiers to further strengthen the immune response and decrease the risk of viral shedding
  • Safe and convenient – Synthetic delivery systems present no risk of genotoxicity (i.e., no virus or cytotoxicity) and require no device; it also improves treatment compliance and makes it very convenient to handle immunization campaigns with suitability for potential pandemic control
  • Flexible manufacturing – Versatile platform enables rapid response to changing pathogens; better stability and shelf life at workable refrigerated temperatures which simplifies handling and distribution

About IMUNON, Inc.

IMUNON is a fully integrated, clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies.

IMUNON has two platform technologies: the TheraPlas modality for the development of immunotherapies and other anti-cancer nucleic acid-based therapies, and the PLACCINE modality for the development of nucleic acid vaccines for infectious diseases and cancer. The company’s lead clinical program, GEN-1, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer currently in Phase II development. GEN-1 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the company is conducting preclinical proof-of-concept studies to validate its PLACCINE modality by using a vaccine design comprising a single plasmid DNA molecule containing a sequence encoding more than one of the SARS-CoV-2 spike antigen variants. IMUNON’s platform technologies are based on the delivery of nucleic acids with novel synthetic delivery systems that are independent of viral vectors or devices. IMUNON will continue to leverage these modalities and to advance the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions. For more information, visit
