Personalized neoantigen vaccine combined with radiotherapy for advanced tumors

Individualized Tumor Neoantigen Peptide Vaccine in Combination with Unusual Immune Stimulating Radiotherapy in Refractory Solid Tumors (iNATURE) - a Phase II Randomized and Crossover Study

Phase 2 Interventional The University of Hong Kong-Shenzhen Hospital · NCT06314087

This study is testing a personalized vaccine made from a patient's own tumor cells combined with radiotherapy to see if it can help people with advanced tumors that haven't responded to standard treatments.

What this trial studies

This study aims to evaluate the effectiveness and safety of an individualized tumor neoantigen peptide vaccine in combination with radiotherapy for patients with advanced malignant solid tumors that have not responded to standard treatments. Patients will undergo tumor tissue collection and genomic analysis to identify specific neoantigens, which will then be used to create a personalized vaccine. The study will monitor tumor burden, immune response, and patient survival following treatment. The approach involves a multi-step process including sequencing, neoantigen prediction, and validation by multiple teams to ensure accuracy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with advanced or recurrent malignancies that have failed standard therapies and have measurable lesions.

Not a fit: Patients with early-stage tumors or those who have not yet undergone standard treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel and effective treatment option for patients with advanced tumors who have limited therapeutic options.

How similar studies have performed: While the use of neoantigen vaccines is a growing area of interest, this specific combination with radiotherapy is relatively novel and has not been extensively tested in prior studies.
