Indaptus Therapeutics announces interim data from Phase 1 INDP-D101 trial

Indaptus Therapeutics announces interim data from the first cohort of four patients in the Phase 1 INDP-D101 trial of its lead compound, Decoy20. A broad expression of cytokines and chemokines associated with innate and adaptive anti-tumor immune responses was observed, while adverse events were generally tolerable and resolved within 30 minutes to three days. Decoy20 is designed to “re-set” the immune system’s response to cancer. The poster was presented on November 4, 2023, at the Society for Immunotherapy of Cancer in San Diego “We are impressed that we saw short-term induction of more than 50 cytokines, chemokines and biomarkers and believe this is unprecedented with a single agent. These early data support our long-standing hypothesis that the Decoy platform may induce robust immune responses across multiple types of immune cells that we believe are important for the eradication of solid tumors,” commented Indaptus CEO Jeffrey Meckler. As reported in the poster, trial subjects experienced transient induction of over 50 different biomarkers associated with immune responses, and generally anticipated transient adverse events. After the end of infusion, Decoy20 was cleared from the blood within 30 to 120 minutes. This rapid clearance and associated transient cytokine/chemokine induction are desired to avoid prolonged toxicity, often associated with longer term cytokine exposure. In contrast, therapeutics that are designed to be continuously present over weeks, months, or even years, such as CAR-T, can induce this type of toxicity. Peak cytokine and chemokine induction occurred within ~4 to 24 hours and most returned to baseline by 24-48 hours.
