Sirnaomics Publishes Data for Lead Candidate STP705 in Cancer Model as 2019 ASCO Abstract



Sirnaomics, Inc., a biopharmaceutical company engaged in the discovery and development of RNAi therapeutics against cancer and fibrotic diseases, today announced the results showing STP705 inhibits the growth of HuCCt-1 (a human cholangiocarcinoma cell line) as a xenograft tumor in nude mice. The work is published as an online abstract at the 2019 American Society of Clinical Oncology Annual Meeting.


Abstract Title: Effect on tumor growth by TGF-β1/COX-2 siRNA combination product (STP705) in a human cholangiocarcinoma (HuCCT-1) xenograft tumor model in nude mice

Cholangiocarcinoma (CCA) is the second most common form of incurable hepatobiliary cancer and represents a massive health care burden worldwide with no effective treatment. Over expression of the genes for TGF-β1 and COX-2 have been well-characterized as playing key roles in tumorigenesis of CCA. STP705 consists of a combination of 2 siRNAs silencing the TGF-β1 and COX-2 genes delivered using a polypeptide nanoparticle delivery system based on Histidine-Lysine co-Polymer (HKP). We have demonstrated that STP705 inhibits the growth of HuCCt-1 xenograft tumors in nude mice (a human cholangiocarcinoma model) and the data is presented in the abstract.
