About PHIO
Phio Pharmaceuticals Corp., founded in 2011 and headquartered in Marlborough, Massachusetts, is a biotechnology company dedicated to developing innovative immuno-oncology therapeutics. The company's core technology is the INTASYL therapeutic platform, which focuses on precisely targeting tumor and immune cells by regulating genes critical to the immune system's function. This approach aims to enhance the body's natural ability to fight cancer. Phio's lead product candidates include PH-762, designed to activate immune cells to recognize and kill cancer cells by reducing the expression of the checkpoint protein PD-1. PH-894 silences the epigenetic protein BRD4, an intracellular regulator of gene expression, while PH-804 targets the suppressive immune receptor TIGIT, a checkpoint protein present on T cells and natural killer cells. All three are being developed for use in adoptive cell transfer (ACT). Formerly known as RXi Pharmaceuticals Corporation, Phio Pharmaceuticals changed its name in November 2018 to reflect its strategic focus on immuno-oncology. The company collaborates with AgonOx Inc. to advance the clinical development of novel T cell-based cancer immunotherapies, underscoring its commitment to partnerships that accelerate the development of its innovative therapies. With a small team of 5 employees, Phio is focused on maximizing the potential of its INTASYL platform to create effective cancer treatments.
