In Situ Tumor Delivery of IL-15 superagonist via RedTail Gene Therapy Achieves Durable Tumor Clearance (SITC 2025) - "CLD-401 transforms tumors into producers of an IL-15 superagonist (IL-15(N72D)-IL-15Rα), a next-generation cytokine known to activate and expand natural killer (NK) cells and CD8+ T cells—both critical for antitumor immunity and with demonstrated clinical efficacy.Methods The resistance of RT to humoral immunity was assessed using modified plaque assays...This strategy achieved complete responses in metastatic models and induced durable immunological memory. The RedTail platform offers a promising approach for localized delivery of diverse therapeutic payloads while minimizing systemic toxicity, addressing a critical challenge in the treatment of metastatic disease."

Systemic antitumor virotherapy: Pre-clinical evaluation of tumor targeting, efficacy, and safety of lead candidate (CLD-401). (ASCO 2025) - "We have developed a new scalable process to manufacture extracellular enveloped antitumor virotherapies and identified the first lead candidate from RTNova Platform, designated as CLD-401. This candidate, CLD-401, demonstrates promising therapeutic efficacy and safety in preclinical models. It effectively addresses the challenge of targeting and treating metastatic lung cancer by delivering Immunotherapeutics directly to disseminated tumors."
