Therapeutic efficacy of oncolytic adenovirus YSCH-01 in osteosarcoma evaluated in PDX and CDX mouse models. (PubMed, Sci Rep) - "In both cell line and patient derived xenograft models, YSCH-01 exhibited potent therapeutic effects with the activated type I interferon signaling pathway in tumor tissues, particularly in terms of its distant effects. Furthermore, this study found out the key signal pathways through which YSCH-01 exerts its antitumor effects in osteosarcoma, which pinpointed potential therapeutic targets by identifying the type I interferon signaling pathway as the candidate molecular markers and their correlation with patient outcomes, positioning YSCH-01 as a promising candidate for osteosarcoma treatment."

IL-8-Induced Tumor Self-Rampart Spatially Confines Oncolytic Virotherapy in Glioblastoma. (PubMed, Neuro Oncol) - "Glioblastoma mounts a spatial self-protective defense through IL-8-driven TSR formation that restricts oncolytic virus spread. IL-8 functions as both a pharmacodynamic biomarker and a therapeutic target, and its inhibition provides a rational strategy to overcome resistance and optimize GBM virotherapy."

Yuansong Bio's registration clinical trial is being actively promoted, and the first patient has completed the first dose [Google translation] (Eastmoney.com) - P1 | N=49 | ChiCTR2400083915 | "On June 17 , 2024, the sub-center launch meeting for the registration clinical trial (YSCH-01-CN001) of Yuansong Bio's oncolytic virus product YSCH-01 was successfully held at the Hangzhou First People's Hospital. The informed consent procedure for the first patient in this trial was completed in the afternoon of the same day, and the first dosing of the first patient was completed at the center on June 27. No dose-limiting toxicity (DLT) has been observed so far, indicating that the registration Phase I/IIa clinical trial of YSCH-01 has entered the substantive research stage and its safety has been preliminarily verified....The second and third patients have completed the informed consent procedure and are about to be enrolled, which fully demonstrates the trust and support of multi-center researchers and patients for the YSCH -01 clinical trial."

Double-modified oncolytic adenovirus armed with a recombinant interferon-like gene enhanced abscopal effects against malignant glioma. (PubMed, Neurooncol Adv) - "Furthermore, we employed a patient-derived xenograft model of recurrent glioblastoma to test the effectiveness of YSCH-01 against temozolomide. Our initial findings confirm that a double-modified oncolytic adenovirus armed with a recombinant interferon-like gene is both safe and effective in the treatment of malignant glioma. Furthermore, when utilized in combination with a targeted therapy gene strategy, these oAds exhibit a more profound effect in tumor therapy and an enhanced ability to inhibit tumor growth at remote sites."
