LAWRENCEVILLE, N.J., May 11, 2023 (GLOBE NEWSWIRE) -- IMUNON, Inc. (NASDAQ: IMNN), a clinical-stage drug-development company focused on developing non-viral DNA-mediated immunotherapy and next-generation vaccines, today announced financial results for the three months ended March 31, 2023, and provided an update on its clinical development programs with IMNN-001 (formerly GEN-1), a DNA-based interleukin-12 (IL-12) immunotherapy in Phase 2 clinical development for the treatment of advanced-stage ovarian cancer, and PLACCINE, a proprietary, multivalent DNA plasmid technology utilizing synthetic, non-viral vaccine delivery vectors being evaluated in preclinical studies for superiority over the current generation of nucleic acid vaccines.
Highlights of the first quarter of 2023 and recent weeks include:
“Our PLACCINE modality continues to advance with very promising data. We demonstrated the validity of this proprietary technology in prophylactic vaccines, with impressive proof-of-concept data in a COVID-19 model coupled with final data from non-human primate studies showing excellent immunological response and viral clearance. We also demonstrated in a recent mouse study that a single dose of our PLACCINE vaccine without a booster dose produced longer duration of IgG responses and higher T-cell activation than an mRNA vaccine. We are now more than nine months into a 12-month PLACCINE stability study and have demonstrated continued drug stability at the standard refrigerated temperature of 4°C, representing a significant commercial advantage over mRNA-based vaccines,” said Dr. Corinne Le Goff, IMUNON’s President and Chief Executive Officer.
“In March we applied for a pre-IND consultation with the U.S. Food and Drug Administration (FDA) to receive guidance on our proposed program for our seasonal COVID-19 booster vaccine prior to submitting an Investigational New Drug (IND) application with the FDA in the fourth quarter of 2023. Our objective is to confirm in a Phase 1 clinical study the safety of our PLACCINE modality. We will also select our next pathogen target for our PLACCINE modality. We likely will choose a pathogen from the list of priority pathogens established by the Coalition for Epidemic Preparedness Innovations. Our vaccine program objective is to establish the safety and efficacy of our platform in a Phase 1 human study, and then seek to license this powerful technology to pharmaceutical companies for the utilization of our platform and/or to establish non-dilutive partnerships to develop vaccines for pathogens of interest,” she added.
“We have now developed an in-house pilot manufacturing capability for DNA plasmids and nanoparticle delivery systems. Our scientists can select any protein from the human or pathogen proteomes to be engineered. Our existing labs also have the ability to conduct testing and to run experiments in a variety of animal disease models. These internal capabilities will allow us to control both the costs and the development timelines in support of our goal to attract corporate partners.
“With the continued volatility of the public equity markets, our decision to raise significant capital in 2021 and early 2022 to extend our cash runway into 2025 was well timed. We expect to report several value-creating developments over the next six to 18 months, among them reporting additional interim data on IMNN-001 from our OVATION 2 Study and the combination study with bevacizumab in advanced ovarian cancer, reporting topline data from the OVATION 2 Study, filing the IND for our SARS-CoV-2 vaccine and announcing proof-of-concept vaccine data for our next pathogen,” Dr. Le Goff concluded.
RECENT DEVELOPMENTS
PLACCINE: Developing the Prophylactic Vaccines of the Future
Presentation at Vaccine Technology Summit 2023 Describes Compelling Preclinical Data Supporting Continued Development of PLACCINE as a Differentiated, Next-Generation Vaccine. In March 2023 Khursheed Anwer, Ph.D., IMUNON’s Executive Vice President and Chief Science Officer, presented data on the Company’s PLACCINE platform at the Vaccine Technology Summit 2023. Dr. Anwer’s presentation is titled “A Novel DNA Vaccine Platform with Potential to Create Next Generation Vaccines,” and can be found on the Company’s website here.
Dr. Anwer reviewed the company’s work in advancing its PLACCINE modality and the promising preclinical data generated to date. Among topics presented was the ability of this multi-valent technology to achieve broad spectrum immunity from a single DNA plasmid with a synthetic delivery system. This ability is independent of virus, device or liquid nanoparticle formulations. The data presented showed:
In addition, the PLACCINE modality had important distinguishing advantages for a commercial vaccine, including a shelf-life at 4⁰C for greater than nine months, and the ability for simple, rapid and scalable manufacturing.
IMNN-001 Immunotherapy
Phase 1/2 Clinical Study of IMNN-001 in Combination with Bevacizumab in Advanced Ovarian Cancer was Opened to Enrollment. In February 2023, the company announced a collaboration to evaluate IMNN-001 in a Phase 1/2 clinical trial in combination with bevacizumab in ovarian cancer in the frontline, neoadjuvant setting. Working with four of the foremost comprehensive cancer centers in the world, the goal of this project is to transform the care of women with ovarian cancer by developing unprecedented capabilities for understanding and targeting persistent minimal residual disease (MRD), as explained here.
This new Phase 1/2 study is expected to enroll 50 patients with Stage III/IV advanced ovarian cancer and is being led by principal investigator Amir Jazaeri, M.D., Professor of Gynecologic Oncology and Reproductive Medicine at MD Anderson. A third party will partially fund the study.
The trial is open to enrollment at the University of Texas MD Anderson Cancer Center with expected additional participation at The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins and Memorial Sloan Kettering Cancer Center. The Koch Institute for Integrative Cancer Research at the Massachusetts Institute of Technology will provide artificial intelligence services throughout the trial, including biomarker and genomic analyses, which is expected to expand the company’s knowledge of the treatment paradigm.
Presentation at American Association for Cancer Research (AACR) Describes Findings from Mouse Model of Peritoneally Disseminated Ovarian Cancer Suggest Biweekly Dosing Regimen for Further Evaluation in Human Clinical Studies. In April 2023 Jean Boyer, Ph.D., IMUNON’s vice president of preclinical research, presented a poster titled “Efficacy of IMNN-001, an Interleukin-12 Immune Gene Therapy, at Different Dose Frequencies” at AACR. The poster can be found on the company’s website here.
Researchers concluded that IMNN-001 demonstrated stimulation of the immune response in the ID8 ovarian tumor model. Of the three dosing regimens tested, the once every 2-week regimen demonstrated comparability to the weekly regimen while showing superiority to the once every 3-week regimen, particularly with respect to mortality and tumor burden. Thus, exploring once every 2-week dosing of IMNN-001 in human studies is warranted.
Partnerships. Collaborations and Corporate Developments
Collaborative Research Agreement Signed with The Wistar Institute’s Vaccine & Immunotherapy Center. In January 2023, the Company announced a collaborative research agreement with The Wistar Institute, a global leader in biomedical research, through its Vaccine & Immunotherapy Center, to research and develop new vaccine formulations utilizing the Company’s PLACCINE modality for the development of vaccines for infectious diseases. The Wistar Institute Vaccine & Immunotherapy Center possesses world-renowned expertise in cancer, immunology, infectious diseases and vaccine creation. They are uniquely positioned to advance new vaccine formulations and will facilitate further expansion and development of PLACCINE with the goal of expanding vaccine targets ideally matched for the Company’s novel formulated DNA delivery platform.
Received $1.6 Million in Non-Dilutive Funding from the Sale of New Jersey Net Operating Losses. In January 2023, the Company announced it received $1.6 million in net cash proceeds from the sale of approximately $1.7 million of its unused New Jersey net operating losses (NOLs). The NOL sales cover the tax year 2021 and are administered through the New Jersey Economic Development Authority’s (NJEDA) Technology Business Tax Certificate Transfer (NOL) program. This non-dilutive funding further strengthened the Company’s balance sheet. The Company plans to sell an additional $1.9 million of unused New Jersey NOLs available to the Company under the program in 2023.
FIRST QUARTER FINANCIAL RESULTS
IMUNON reported a net loss for the first quarter of 2023 of $5.6 million, or $0.68 per share, compared with a net loss of $10.5 million, or $1.82 per share, for the first quarter of 2022. Operating expenses were $5.7 million for the first quarter of 2023, a decrease of $0.3 million or 5% from $6.0 million for the first quarter of 2022.
Net cash used for operating activities was $4.1 million for the first quarter of 2023, compared with $8.0 million for the comparable prior-year period. This decrease was primarily due to the one-time payment of $4.5 million in interest expense resulting from the sale and subsequent redemption of $30.0 million of convertible, redeemable preferred stock during the first quarter of 2022.
Cash provided by financing activities of $2.5 million during the first quarter of 2023 resulted from equity sales under the Company’s At-the-Market Equity Facility. The Company had $37.3 million in cash, investments and restricted cash as of March 31, 2023. Combined with $1.9 million in planned future sales of the Company’s State of New Jersey NOLs, the Company believes it has sufficient capital resources to fund its operations into 2025.
Research and development (R&D) expenses were $2.6 million for the first quarter of 2023, a decrease of $0.5 million from $3.1 million for the comparable period in 2022. R&D costs associated with the development of IMNN-001 to support the OVATION 2 Study as well as development of the PLACCINE DNA vaccine technology platform increased to $1.7 million for the first quarter of 2023, compared with $1.9 million for the same period of 2022. Other clinical and regulatory costs were $0.3 million for the first quarter of 2023, compared with $0.8 million for the first quarter of 2022. CMC costs increased to $0.7 million for the first quarter of 2023, compared with $0.3 million for the first quarter of 2022 due to higher costs related to the development of in-house pilot manufacturing capabilities for DNA plasmids and nanoparticle delivery systems.
General and administrative expenses were $3.1 million for the first quarter of 2023, compared with $2.9 million for the comparable prior-year period. This increase was primarily attributable to lower non-cash stock compensation expense offset by higher professional fees, including legal fees to defend various lawsuits filed after the announcement in July 2020 of the OPTIMA Phase 3 study results, higher compensation expenses related to the CEO succession plan announced in July 2022 and higher staffing costs.
Other non-operating income was $93,085 for the first quarter of 2023, compared with other non-operating expenses of $4.6 million for the prior-year period. In the first quarter of 2022, the Company incurred a one-time payment of $4.5 million in interest and offering expenses resulting from the sale and subsequent redemption of $30.0 million of convertible redeemable preferred stock. The Company incurred higher interest expense on its loan facility with Silicon Valley Bank in the first quarter of 2023 due to rising interest rates. This loan facility has since been assumed by First Citizen Bank under the same terms. Investment income from the Company’s short-term investments increased by $0.3 million for the first quarter of 2023 compared with the prior-year period due to higher returns on these investments.
