IMUNON Submits Plan in Consultation with the Exchange to Ensure Compliance with Nasdaq’s Listing Requirement, Anticipates Additional Compliance Period

LAWRENCEVILLE, N.J., June 30, 2025 (GLOBE NEWSWIRE) -- IMUNON, Inc. (NASDAQ: IMNN), a clinical-stage company in Phase 3 development of its DNA-mediated immunotherapy, today announced that, in consultation with The Nasdaq Stock Market LLC (Nasdaq), it has submitted its plan to Nasdaq to regain compliance with the minimum bid price requirement and the minimum stockholders’ equity requirement for continued listing on The Nasdaq Capital Market. On May 29, 2025, the Company requested a hearing before The Nasdaq Hearings Panel (“Panel”). At this hearing, the Company will request an extension to meet the requirements and return to compliance. In an exchange with Nasdaq, the Company has established a pathway to an additional compliance period of 180 calendar days to regain compliance with the minimum bid price requirement and the minimum stockholders’ equity requirement, subject to final review by the Panel. Pursuant to Nasdaq Listing Rule 5815(a)(1)(B), the hearing request stayed the suspension of trading and delisting of the common stock pending the conclusion of the hearing process.

“We are confident that our plan demonstrates our ability to regain compliance with Nasdaq's listing requirements, an important step that reflects our commitment to advancing our lead clinical program, IMNN-001, a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer which is now in a Phase 3,” said Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON. “We have made substantial progress following our unprecedented Phase 2 (OVATION 2) trial results, including initiating our Phase 3 (OVATION 3) trial in the U.S. and Canada, and look forward to achieving additional milestones in the development of our innovative TheraPlas® and PlaCCine® technology platforms.”

Following the completion of several recent financial transactions, the Company’s stockholders’ equity as of May 31, 2025, exceeds $3.0 million and is above the listing threshold established by NASDAQ.

IMUNON is a 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 is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the gene-based delivery of cytokines and other therapeutic proteins in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the gene delivery of viral antigens that can elicit a strong immunological response.

The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase 2 clinical trial (OVATION 2). IMNN-001 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 has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.
