Summary

This Ⅱ study evaluates the safety and efficacy of intratumoral injection of OH2 in locally advanced or metastatic bladder cancer. OH2 is an oncolytic virus developed upon genetic modifications of the herpes simplex virus type 2 strain HG52, allowing the virus to selectively replicate in tumors. Meanwhile, the delivery of the gene encoding human granulocyte macrophage colony-stimulating factor (GM-CSF) may induce a more potent antitumor immune response.

Detailed description

This is a phase Ⅱ study evaluating the efficacy and safety of OH2 in locally advanced or metastatic bladder cancer. BH-OH2-017 is a single-arm,multicenter clinical trial. The OH2 injection will be delivered once two weeks. In the maintenance treatment period, OH2(1x10e7 CCID50/mL) will be delivered once a month. Adverse events (AEs) are graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) (version 5.0). Radiographic imaging studies are performed using computed tomography or magnetic resonance imaging. Measurement of cutaneous or subcutaneous lesions are conducted with calipers. Evaluation of response are performed by the investigators using both the RECIST version 1.1 and the iRECIST criteria.
