(Nasdaq: PHIO), a clinical stage biotechnology company whose proprietary INTASYL™ RNAi platform technology is designed to make immune cells more effective in killing tumor cells, today announced that in vivo data from a mouse model of colon cancer demonstrates target synergy-enhanced anti-tumor efficacy from a novel dual-targeting mouse PD-1 and CTLA-4 of an INTASYL coformulation.

Intratumoral administration of the PD-1/CTLA-4 INTASYL improved tumor control compared to either single targeting formulation, at an identical total dose. The dual-targeting formulation was well tolerated.
"The synergistic effects of dual inhibition of PD-1 and CTLA-4 in enhancing tumor response are clinically recognized, however, a high rate of immune-related adverse events limits the utility of systemic use of this combination of products," said Dr. Mary Spellman, Phio's Acting Chief Medical Officer. "Intratumoral administration of dual-targeting PD-1/CTLA-4 INTASYL may provide an effective treatment option, with an improved safety profile."

Poster Title: | INTASYL self-delivering RNAi therapeutic dual targeting PD-1 and CTLA-4 |
