Phio Pharmaceuticals (NASDAQ: PHIO) announced positive results from the second cohort of its Phase 1b clinical study of PH-762. The study evaluates the safety and tolerability of intratumoral PH-762 in various skin cancers. Two patients with cutaneous squamous cell carcinoma achieved complete response (100% tumor clearance) at Day 36. Among other patients in the second cohort, one showed partial response (90% tumor clearance) and another had stable disease.
The trial included 7 patients total, with 6 diagnosed with cutaneous squamous cell carcinoma and 1 with metastatic melanoma. Importantly, no dose-limiting toxicities or clinically relevant treatment-emergent adverse events were reported, and the intratumoral injections were well tolerated. The study continues to enroll patients to assess higher dose concentrations of PH-762.
Phio Pharmaceuticals (NASDAQ: PHIO) announced the publication of research on RXI-231, an INTASYL compound designed to treat hyperpigmentation, in Clinical, Cosmetic and Investigational Dermatology's December 2024 issue. The study demonstrates that RXI-231 effectively reduces tyrosinase (TYR) gene expression and melanin content in human melanocytes and 3D epidermal cultures.
The research shows that applying RXI-231 every other day visibly reduced pigmentation in 3D epidermal cultures. Testing using the MatTek EpiDerm Skin Irritation model confirmed the compound's non-irritant profile. While additional clinical testing is required, RXI-231 shows promise for treating hyperpigmentation disorders.
