Phio Pharmaceuticals Corp. announced it is presenting new data about INTASYL on March 21st. The event is scheduled to take place at the 10th Immunotherapy of Cancer Conference (ITOC10), which will be held in Munich, Germany from March 21-23, 2024.

The poster, Enhancing NK cell cytotoxicity against tumor cells with a novel self-delivering RNAi compound targeting Cbl-b, reveals new preclinical data demonstrating the potential of treatment with INTASYL self-delivering siRNA Compound PH-905, formerly known as Compound 27547, to improve function of natural killer (NK) cells. The data reveals a consistent silencing of Cbl-b mRNA, which has been shown to limit NK cell activation. Cytotoxic activity of NK cells against K562 (Chronic Myelogenous Leukemia) cancer cells was also increased.

By reducing the expression of Cbl-b, INTASYL promotes NK cell activation and proliferation. These preclinical data demonstrate the potential of INTASYL Compound PH-905 to improve Adoptive Cell Therapy (ACT) by targeting and silencing Cbl-b. This may result in a more effective cell therapy for hematological malignancies. INTASYL is the only self-delivering RNAi technology focused on immuno-oncology therapeutics.

INTASYL drugs precisely target specific proteins that reduce the body's ability to fight cancer, without the need for specialized formulations or drug delivery systems.
