NCT07382531

Brief Summary

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.

Conditions

Outcome Measures

Primary Outcomes (3)

  • Incidence of AE (Adverse Event) and SAE (Serious Adverse Event)

    Toxic reactions according to the NCI-CTCAE 5.0 grading standard that occur within 3 weeks from the first administration, are judged to be drug-related by the investigator, and meet the non-hematological toxicity and hematological toxicity conditions specified in the clinical protocol

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

  • DLTs (Dose Limiting Toxicity)

    Toxic reactions according to the NCI-CTCAE 5.0 grading standard that occur within 4 weeks from the first administration, are judged to be drug-related by the investigator, and meet the non-hematological toxicity and hematological toxicity conditions specified in the clinical protocol

    4 weeks from the first administration

  • MTD

    If ≥2/6 subjects developed DLT, the previous dose group was MTD

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

Secondary Outcomes (5)

  • ORR/iORR

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

  • DOR/iDOR

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

  • PFS/iPFS

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

  • DCR/iDCR

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

  • OS

    Through study completion, six months after the last administration of the study drug to the last enrolled subject.

Study Arms (1)

OH2+BS006

EXPERIMENTAL

The administration method consists of sequential intratumoral injections of OH2 and BS006 at an equal volume ratio. Administration occurs once every 2 weeks (Q2W) until the investigator determines that the subject no longer derives clinical benefit and exhibits significant clinical disease progression (radiographic progression is not a mandatory criterion for treatment discontinuation), or until the treatment is no longer tolerated, or the clinical trial concludes. For each administration, subjects may receive a maximum of 6 mL each of OH2 Injection and BS006 Injection.

Biological: OH2+BS006

Interventions

OH2+BS006BIOLOGICAL

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.

You may qualify if:

  • \. Patients with unresectable stage III or IV malignant tumors confirmed by pathology and/or cytology; such as malignant melanoma, head and neck tumors, soft tissue sarcoma, liver tumors (primary hepatocellular carcinoma or liver metastases), biliary tract tumors, pancreatic cancer, esophageal cancer, gastric cancer, etc.
  • \. Lack of standard effective treatment options, or failure of or relapse after standard treatments.
  • Male or female patients aged 18-75 years (inclusive); Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1; expected survival of more than 3 months.
  • \. At least 4 weeks have elapsed since completion of prior antitumor therapies (including endocrine therapy, chemotherapy/radiotherapy, and targeted therapy) (except radiotherapy for bone metastases); for patients treated with nitrosoureas or mitomycin, at least 6 weeks since discontinuation; and recovery from prior treatment-related adverse effects to Grade 1 or lower.
