About STP705

Sirnaomics’ product candidate, STP705, is a siRNA (small interfering RNA) therapeutic that takes advantage of a dual-targeted inhibitory property and polypeptide nanoparticle (PNP)-enhanced delivery to directly knock down both TGF-β1 and COX-2 gene expression. The product candidate has received multiple IND approvals from both the US FDA and Chinese NMPA, including for the treatment treatments of cholangiocarcinoma and other solid liver tumors, nonmelanoma skin cancer and hypertrophic scar, and Keloid scarring. STP705 has also received Orphan Drug Designation for treatment of cholangiocarcinoma, primary sclerosing cholangitis, and hepatocellular carcinoma. A Phase 2a study of STP705 for treatment of squamous cell skin cancer (isSCC) in adult patients demonstrated positive efficacy and safety results, with 76% of all patients (19/25) achieving complete histologically clearance and the two optimal dosing ranges achieving 90% histological clearance of tumor cell in the lesion. No significant or serious adverse events, including no significant cutaneous skin reactions, were reported in the study, and the company was able to define a clear therapeutic window in advance of later stage studies.
