Clinical trials

BS008-001 is a multicenter, open-label phase Ib /II trial in heavily pre-treated patients with advanced solid tumors. Patients received biweekly sequential intratumoral injections of OH2 (fixed dose: 10⁷ CCID₅₀/mL) followed by BS006 (dose escalation: 10⁶-10⁷ CCID₅₀/mL), with identical volumes being injected at the same lesion. The primary endpoint is safety and tolerability; secondary endpoints included efficacy outcomes assessed by RECIST 1.1/iRECIST.

To evaluate the efficacy of OH2 injection in patients with unresectable or metastatic melanoma who have failed at least second-line standard therapy, using investigator-selected salvage chemotherapy or best supportive care (BSC) as controls.

This phase Ib study evaluates the safety and efficacy of OH2 in combination with HX008, an anti-PD-1 antibody, in patients with Melanoma. 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.

This study will be a Phase 1, multi-center, open-label, dose escalation followed by the recommended phase 2 dose (RP2D) expansion study to characterize safety, tolerability, biodistribution, virus shedding and preliminary efficacy of intratumoral injection of OH2 in patients with locally advanced/metastatic solid tumors.

An open-label dose-escalation phase I clinical study to evaluate the safety, tolerability and pharmacokinetics of OH2 injection via transcatheter Intraarterial infusion in patients with advanced hepatocellular carcinoma

This phase I/II study evaluates the safety and efficacy of OH2 as single agent or in combination with HX008, an anti-PD-1 antibody, in patients with malignant solid tumors (gastrointestinal cancers, head and neck cancers, soft tissue sarcomas). 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.

This phase Ⅰb/Ⅱ study evaluates the safety and efficacy of OH2 for adjuvant therapy in non-muscle-invasive bladder cancer after first-line prophylactic intravesical instillation therapy. 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.
