Imunon, Inc. (CLSN): Mission and Values

• TheraPlas®: a non‑viral DNA delivery system that encodes cytokines and therapeutic proteins and is administered directly to or near tumor tissue to create high local concentrations of immune‑stimulatory molecules.
• PlaCCine®: a gene‑based platform that delivers DNA encoding viral antigens to stimulate robust humoral and cellular immunity for prophylactic and booster vaccine applications.

• Mechanism: encodes interleukin‑12 and interferon‑gamma to induce localized innate and adaptive immune activation, increase tumor‑infiltrating lymphocytes, and enhance antigen presentation.
• Administration: intratumoral or intralesional delivery to concentrate cytokine expression at the tumor site and reduce systemic exposure.
• Clinical aim: promote tumor microenvironment remodeling, antigen spreading, and synergy with checkpoint inhibitors or other systemic therapies.

• Mechanism: delivers SARS‑CoV‑2 antigen genes to stimulate a broad immune response, boosting neutralizing antibodies and T‑cell immunity.
• Positioning: designed as a durable, gene‑based booster to complement existing vaccine strategies and address waning immunity or variant emergence.

• Targeted expression: localized DNA delivery concentrates therapeutic proteins at disease sites (e.g., tumors), aiming for efficacy with reduced systemic adverse events relative to systemic cytokine therapy.
• Non‑viral delivery: avoids potential risks associated with viral vectors (anti‑vector immunity, insertional concerns) and enables repeat dosing.
• Platform versatility: same delivery backbone supports oncology payloads (cytokines, immune modulators) and vaccine payloads (viral antigens), shortening development timelines for new indications.

• Advance IMNN‑001 through current early‑phase clinical trials and explore combination regimens with checkpoint inhibitors.
• Progress IMNN‑101 as a gene‑based booster candidate, including studies assessing immunogenicity against circulating SARS‑CoV‑2 variants.
• Pursue partnerships for global development, manufacturing scale‑up, and commercialization to monetize platform assets.

• Durable local expression of therapeutic proteins can reduce dosing frequency and enhance patient adherence.
• Platform amenable to rapid antigen or payload swaps to address emerging variants or new oncology targets.
• Non‑viral approach supports a favorable safety profile for repeat administrations in chronic or prophylactic settings.
