Personalized Vaccination in Fusion+ Sarcoma Patients (PerVision)
Germany30 participantsStarted 2023-09-19
Plain-language summary
The PerVision trial utilizes an approach of a patient-individual cancer vaccine with sarcoma-specific peptides in metastasized fusion-driven sarcoma patients determined by next generation whole exome sequencing of tumor and normal tissue as well as RNA sequencing of the tumor.
This approach is applicable to all patients independent of the expression of distinct tumor associated antigens, and independent of their human leukocyte antigen-typing (HLA-typing). The results of this study can directly be translated to other tumor entities.
It is an interventional, multicenter, open-label, phase I/II feasibility and early proof of concept study evaluating a personalized peptide vaccine.
Primary objective is to evaluate safety and success of treatment, the latter be defined as vaccination-induced T-cell response without unacceptable toxicity.

Inclusion Criteria, definition of partial remission plus (PRplus)
* Screening Stage 1:
* Confirmed metastatic fusion-driven rhabdomyosarcoma, Ewing- and synovial sarcoma in first or second complete remission (CR) or partial response (PR) after local therapy and intensive standard chemotherapy protocols.
* Whole exome sequencing and RNA sequencing data of the gene fusion (fusion-breakpoint RNA sequence) must be available by registration to the INFORM (Individualized therapy for relapsed malignancies in childhood), MASTER (Register study Molecularly Aided Stratification for Tumor Eradication) or HEROES-AYA networks (Heterogeneity, evolution and resistance of fusion-driven sarcomas in AYA) or similar evaluation.
* Screening stage 2:
* Design and production of the patient-individual vaccine cocktail was successful
* Patients have reached a complete or stable partial remission (CR or PR) the end of adjuvant and/or maintenance cytotoxic treatment. Cytotoxic treatment as per standard or trial recommendations has been completed. Definition of PRplus: Partial remission(plus) implicates that all remaining tumor residua including all metastases have received local therapy by this time point: Either surgical removal or local irradiation. The assessment of which therapy modality and, in the case of irradiation, which radiation dose is selected, lies with the treating physician. Whether PRplus is achieved will be decided finally by the investigator after review of the patient re…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
