Experimental vaccine fights sarcoma with Patient's own immune cells
NCT ID NCT07648069
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tests a personalized cancer vaccine (SarcVac) combined with immune-boosting drugs and, in some patients, specially grown immune cells. The goal is to see if this approach is safe and can shrink tumors in 16 adults with advanced bone or soft tissue sarcoma who have not responded to standard treatments. The study is currently recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- personalized tumor neoantigen vaccine (SarcVac) with or without tumor-specific lymphocytes and an anti-PD-1 antibody
- What this could lead to
- If successful, this could point toward a new treatment option for advanced sarcoma patients who have run out of standard therapies.
- What could go wrong
- This is a very early phase 1 trial with only 16 participants, so it is primarily testing safety. The vaccine may not shrink tumors or improve survival, and side effects are unknown.

Inclusion Criteria: 1. Before any procedures related to the research program, including screening and evaluation stage, signed informed consent. 2. Age≥18 years old, and≤70 years old ; 3. Pathologically diagnosed as solid tumors, including bone or soft tissue sarcoma, and staging for advanced or unresectable patients ; 4. Patients with first-line treatment failure ; 5. No previous tumor vaccine treatment ; no previous treatment with PD-1 antibody ; 6. According to the RECIST1.1 standard, there are measurable lesions and superficial lesions ; 7. The following three screening indicators should be met in the test screening period: (1)The available tumor tissue samples ( paraffin sections and fresh surgical specimens ) were used for subsequent whole exome and transcriptome sequencing analysis and primary cell culture to obtain tumor neoantigen-related mutation sequence information and gene expression. ( 2 ) Available peripheral blood samples; ( 3 ) Tumor new antigen prediction analysis and in vitro laboratory testing; 8. ECOG score 0-1 ( see Appendix ) and expected survival time greater than 6 months ; 9. Patients were not allowed to use anti-tumor drugs and radiotherapy within 4 weeks before vaccination; 10. Patients with brain metastasis who were stable for at least one month after treatment can be included; 11. echocardiography showed left ventricular ejection fraction ≥ 50 %; 12. The results of laboratory tests should meet at least the following indicators : 1. White blood cell count ≥ 3.0 × 109 / L; 2. absolute neutrophil count ( ANC ) ≥ 1.5 × 109 / L ( without GCSF support ) ; 3. absolute lymphocyte count ( ALC ) ≥ 1.0 × 109 / L; 4. platelet ( PLT ) ≥ 75 × 109 / L; 5. hemoglobin ≥ 90g / dL ( no blood transfusion in the past 7 days ) ; 6. Prothrombin time or INR ≤ 1.5x normal upper limit time, unless receiving anticoagulant therapy; 7. partial thromboplastin time ( APTT ) ≤ 1.5x normal upper limit time, unless receiving anticoagulant therapy; 8. serum creatinine ≤ 1.5 × ULN ( upper limit of normal ) ; 24-hour creatinine clearance rate ≥ 60 mL / min; 9.
