Oncolytic virus injection for treating relapsed bone and soft tissue tumors

A Clinical Safety and Efficacy Study on Oncolytic Virus Injection (R130) for the Treatment of Relapsed/Refractory Bone and Soft Tissue Tumors

This study is testing a new virus treatment for people aged 14 to 75 with bone and soft tissue tumors that haven't responded to other therapies to see if it helps shrink their tumors.

What this trial studies

This clinical trial evaluates the safety and efficacy of a recombinant herpes simplex virus type 1, known as R130, in patients with relapsed or refractory bone and soft tissue tumors. The study aims to enroll 20 participants who have not responded to standard treatments or are unwilling to pursue further antitumor therapies. Participants will receive intratumoral injections of the oncolytic virus, and their responses will be monitored to assess the treatment's effectiveness. The trial is designed as an open-label, single-arm study, focusing on patients aged 14 to 75 with measurable lesions.

Who should consider this trial

Good fit: Ideal candidates are patients aged 14 to 75 with relapsed or refractory soft tissue sarcoma or bone tumors who have measurable lesions and have failed standard treatments.

Not a fit: Patients with contraindications to intratumoral injections or those who are not willing to participate in this experimental treatment may not benefit.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat bone and soft tissue tumors.

How similar studies have performed: While the use of oncolytic viruses in cancer treatment is an emerging field, this specific approach with R130 is novel and has not been extensively tested in prior studies.

Eligibility criteria

Inclusion Criteria:

4. Subjects with ECoG score of 0-2.
5. Expected survival of 3 months or more.
6. Have at least one measurable lesion (according to RECIST 1.1 criteria) that is amenable to intratumoral drug delivery.
7. Subjects must have appropriate organ function, and laboratory tests during the screening period must meet the following requirements: a) absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelets (PLT) ≥ 80 × 109/L, and hemoglobin (Hb) ≥ 85 g/L; b) serum creatinine (Cr) and blood urea nitrogen (BUN) within 1.5 times the upper limit of normal values; c) serum total bilirubin (TBIL) ≤ 2 times the upper limit of normal values; d) glutamic aminotransferase (ALT) and glutamic oxalacetic aminotransferase (AST) ≤ 2.5 times the upper limit of normal values; subjects with liver metastases do not exceed 5 times the upper limit of normal values; e) activated partial thromboplastin time (APTT), prothrombin time (PT) within 1.5 times the upper limit of normal values.
8. Any treatment for malignancy, including radiotherapy, chemotherapy and biological agents, must be discontinued 28 days prior to R130 treatment.
9. Eligible patients of childbearing potential must agree to use a reliable method of contraception (hormonal or barrier method or abstinence) with their partner for the duration of the trial and for at least 180 days after the last dose; female patients of childbearing potential must have a negative urine pregnancy test within 7 days prior to enrollment.
10. Subjects voluntarily sign an informed consent form and are in good compliance.

Exclusion Criteria:

1. Have had any serious adverse reactions associated with immunotherapy and have not recovered to CTCAE 5.0 grade rating 0 or 1 level of toxicity after previous antineoplastic therapy.

6. Patients with active bleeding or severe coagulation dysfunction.
7. Have had antitumor therapy, including endocrine, chemotherapy, radiotherapy, targeted therapy, immunotherapy and antitumor herbal therapy, 4 weeks prior to the first dose.
8. Current active hepatitis B, active hepatitis C, immunodeficiency virus or other active infection of clinical significance.
9. Patients who have undergone surgery of grade 3 or higher or whose surgical wounds have not healed within 4 weeks prior to enrollment.
10. Pregnant, lactating and planning to have children within six months.
11. Subjects who, in the judgment of the investigator, are unsuitable for participation in this trial for any reason.
