About this trial

This is an interventional treatment trial for Ewing Sarcoma focused on measuring metastasized fusion-driven sarcoma, clinical study, phase I/II

Eligibility Criteria

2 Years - 40 Years (Child, Adult)All SexesDoes not accept healthy volunteers

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 records. Exclusion Criteria: Ejection fraction < 25% Creatinine-clearance < 40ml/min Bilirubin > 4mg/dl Alanine aminotransferase (ALT) > 400 units (U)/l and/or aspartate aminotransferase (AST) > 400 U/l Severe infection (Human immunodeficiency virus (HIV): positive for the presence of human immunodeficiency virus-1 or human immunodeficiency virus-2 (positive antigen/antibody or nucleic acid tests [NAT]) and CD4-positive cells < 500/μl. Hepatitis B virus: positive for the presence of hepatitis B virus (positive for hepatitis B core antibody [HBcAb] or positive hepatitis B surface antigen [HBsAg]) and hepatitis B NAT test > 2000 IU/ml). Hepatitis C virus: positive for heavy chain only antibody [HCAb] or for nucleic acid amplification testing (NAT). Other infections that, in the opinion of the investigator, do not allow a participation in the study.) Subjects with a known hypersensitivity / allergy to any component of the study drugs.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Peptide vaccination

Arm Description

Peptides will be administered subcutaneously (s.c.) together with the novel toll like receptor (TLR) 1/2 ligand XS15 emulsified in Montanide ISA 51 VG as adjuvant. Three vaccinations will be applied every 28 days.

Outcomes

Primary Outcome Measures

Success of treatment
The primary composite safety/efficacy outcome of "treatment success" is defined as number of patients without unacceptable toxicity (any toxicity > grade 3 according to NCI-CTC) until Follow-up visit (28 ± 7 days after last vaccination) and with vaccination-induced response of cluster of differentiation 4+ (CD4+) and/or cluster of differentiation 8+ (CD8+) T cells to the patient-specific peptides at Follow-up visit (28 ± 7 days after last vaccination). CD4+ and CD8+ T cells will be measured by flow cytometry.

Secondary Outcome Measures

T-cell response at follow up
Number of patients with CD8+ and/or CD4+ T-cell responses measured 2-fold above background in response to either of the two patient-specific peptides (fusion-peptide and mutation-based neopeptide).
T-cell response at final follow up
Number of patients with CD8+ and/or CD4+ T-cell responses measured 2-fold above background in response to either of the two patient-specific peptides (fusion-peptide and mutation-based neopeptide).
Event free survival
Rate of patients that survived without progression according to RECIST criteria, stratified for immune response yes/no
Overall survival
Rate of patients that survived. stratified for immune response yes/no
Quality of life (QoL) defined as overall quality of life in children
QoL (Quality of life) is defined as overall quality of life measured by Pediatric Quality of Life InventoryTM PedsQL (4.0). The PedsQL uses a 0 to 4 scale with 0=never and 4=almost always.
Quality of life (QoL) defined as overall quality of life in adults
QoL (Quality of life) is defined as overall quality of life measured by European Organisation for Research and Treatment of Cancer EORTC quality of life questionnaire (QLQ) C-30 (3.0). EORTC QLQ C-30 uses a 1-4 scale with 1=not at all and 4=very much and a 1-7 scale with 1=very poor and 7=excellent.

5. Study Description

Brief 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.
Detailed Description
The PerVision trial utilizes an approach of a patient-individual cancer vaccine with sarcoma-specific peptides (one peptide derived from the sarcoma-specific fusion breakpoint, 'fusion-peptide', and a second peptide derived from neoantigens derived from patient-specific non-synonymous mutations with the highest prediction score, 'mutation-based neopeptide') 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 and the toll like receptor (TLR) 1/2 ligand XS15 emulsified in Montanide ISA 51 VG in fusion driven sarcoma patients. The principal questions are: To investigate, whether it is possible to induce a mutation-specific immune response in sarcoma patients and young adults after salvage chemotherapy To investigate possible side effects and toxicity of the treatment To gather indications if our approach has a beneficial effect on residual disease as well as event free survival (EFS) of the patients. EFS and overall survival (OS) data will be compared within this single arm study to non-vaccinated patients of a historic control cohort. Patients will be recruited through the Society for Pediatric Oncology/Hematology (GPOH) networks Cooperative Soft Tissue Sarcoma Group (CWS) and Cooperative Ewing Sarcoma Group (CESS) and through the "Deutsches Konsortium für Translationale Krebsforschung" (DKTK) programs MASTER and INFORM as well as HEROES-AYA. For the screening phase, n=30 patients will be recruited, n=23 patients should be treated with at least one vaccine dose, with a drop-out rate we need n=21 patients for sufficient statistical power. Primary objective is to evaluate the safety, toxicity and in vivo immunological effects of a patient-individualized peptide vaccination (IPX vaccine) in patients with primary or relapsed metastasized fusion-driven sarcoma (FDS, rhabdomyosarcoma, Ewing- and synovial sarcoma) with an age ≥ 2 to < 40 years in first or second complete remission or stable partial remission. Primary endpoint is "success of treatment", defined as the patient showing a vaccination-induced T cell response without unacceptable toxicity until Follow-up visit (28 ± 7 days after last vaccination).
