Item 1.01 Entry into a Material Definitive Agreement.
On October 20, 2026, Imunon, Inc. (the “Company”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with VoxelDox Therapeutics, Inc. (“VoxelDox”), pursuant to which the Company agreed to sell to VoxelDox the Company’s assets relating to ThermoDox®, a heat-activated liposomal formulation of doxorubicin (the “Purchased Assets”), including related trademarks, regulatory filings, clinical and preclinical data, manufacturing know-how and existing drug product vials. VoxelDox intends to develop ThermoDox for glioblastoma and other high-grade gliomas. The transaction is contingent on VoxelDox raising at least $2.5 million. If it does not raise this funding, the transaction will not close and the Company will receive no consideration.
If the transaction closes, VoxelDox will issue to the Company shares of VoxelDox common stock equal to 4.76% of its fully diluted capitalization. VoxelDox will also pay the Company up to $16.5 million in milestone payments upon the achievement of specified clinical and regulatory milestones, including initiation of a Phase 3 clinical trial of ThermoDox and FDA acceptance and approval of a New Drug Application. In addition, VoxelDox will pay royalties on annual net sales. If VoxelDox determines in good faith that the transferred ThermoDox vials are not usable, milestone payments and royalty rates will be reduced by 50%.
Until VoxelDox completes a qualified equity financing, the Company may appoint one of VoxelDox’s five directors and one non-voting observer. The Purchase Agreement contains customary representations, warranties, covenants and indemnification provisions.
Subject to VoxelDox board approval and separate consulting agreements, VoxelDox will grant Michael H. Tardugno, the Company’s Executive Chairman, and Frederick J. Fritz, a member of the Company’s Board of Directors, shares of VoxelDox common stock each equal to 2.38% of its fully diluted capitalization, vesting monthly over 36 months, for consulting services to VoxelDox. Other than as described above, there is no material relationship between the Company and VoxelDox.
The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the year ending December 31, 2026.

Exhibit 99.1
IMUNON Announces Strategic Sale of ThermoDox®
Agreement with VoxelDox Therapeutics, Inc. Creates a Clear Path to Future Value, Subject to Achievement of Development Milestones in the Planned Phase 1 Glioblastoma Trial
Sale Reinforces IMUNON’s Commitment to Its Core Strategy: Executing the Pivotal Phase 3 OVATION 3 Trial of IMNN-001
LAWRENCEVILLE, N.J., October 21, 2026 — IMUNON, Inc. (Nasdaq: IMNN), a clinical-stage biotechnology company developing DNA-mediated immunotherapies, today announced that it has entered into an agreement to sell its rights to ThermoDox®, a heat-activated liposomal formulation of doxorubicin, to VoxelDox Therapeutics, Inc. (“VoxelDox”). Under the agreement, VoxelDox intends to advance the development of ThermoDox for the treatment of glioblastoma multiforme (GBM), a difficult-to-treat form of brain cancer. In exchange, IMUNON will receive an equity ownership stake in VoxelDox, payments of up to $16.5 million contingent upon meeting development milestones and significant royalties on future net sales of ThermoDox product following commercial approval.
Closing of the transaction is contingent upon VoxelDox completing a planned $2.5 million financing to support initiation of a Phase 1 clinical trial in patients with glioblastoma. The companies are announcing the agreement in advance of closing to provide visibility into the intended transaction and IMUNON’s continued strategic focus. The transaction enables IMUNON to retain potential long-term economic participation in ThermoDox while dedicating its financial and operational resources to advancing IMNN-001, the Company’s lead clinical program.
“We are pleased that ThermoDox has found a steward committed to advancing its development for the benefit of patients,” said Stacy R. Lindborg, Ph.D., President and Chief Executive Officer of IMUNON. “This agreement is consistent with our previously announced strategy to identify a development partner for this promising drug candidate and demonstrates our disciplined approach to portfolio management and capital allocation. By creating a path to realize future value from a legacy asset that has been fully written off, the transaction allows our organization to remain singularly focused on the successful execution of the pivotal Phase 3 OVATION 3 trial of IMNN-001 in frontline advanced ovarian cancer. We look forward to following VoxelDox’s progress as it works to advance this technology for patients with glioblastoma.”
Under the terms of the agreement, upon completion of VoxelDox’s financing, IMUNON will receive an equity interest of approximately 4.76% in VoxelDox, together with the potential to receive up to $16.5 million in aggregate development and sales-based milestone payments and tiered royalties ranging from 3.5% to 6% on net sales of ThermoDox-related products, if approved. IMUNON’s realization of any milestone or royalty payments, or of value from its equity position, is subject to VoxelDox’s success in financing, developing, and, if applicable, commercializing the asset, and there can be no assurance that any such value will be realized.

About IMUNON
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), and is currently being studied in a Phase 3 clinical trial (OVATION 3). 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.
