Overview

Creating new pathways to a cancer-free future for patients

Phio is addressing some of the biggest challenges in immuno-oncology (I/O) by developing therapeutics that leverage our INTASYL™ self-delivering technology to target both tumor and immune cells. The I/O field has recently identified several promising next-generation targets, but conventional approaches such as antibodies and small molecules often fall short of becoming optimal treatments for patients. In contrast to conventional RNA inference (RNAi) platforms, our INTASYL™ enables efficient RNAi delivery into any cell of interest. INTASYL™ therefore brings the benefits of RNAi therapeutics into the I/O space to develop new and potent next-generation I/O therapeutics with favorable drug profiles for patients with cancer.
