Eligibility
Inclusion criteria
Inclusion criteria: 1. Patient under 18 years of age at the time of inclusion. 2. Histopatologically confirmed or suspected histiocytosis (based on prior test results). 3. Signing of informed consent for trial participation according with current legal regulations. Are the trial subjects under 18? yes Number of subjects for this age range: 150 F.1.2 Adults (18-64 years) no F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: 1. Lack of inclusion criteria. 2. Pregnancy. 3. Other acute or persistent disorders, behaviors or abnormal laboratory test results, which might increase the risk related to the participation in this clinical trial or to taking the study drug, or which might influence the interpretation of the study results, or which, in the investigator’s opinion, disqualify a patient from participating in the trial.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Determination of molecular status and benefit and safety of use fludeoxyglucose (18-FDG) in PET/CT imagening in juvenile patients with histiocytosis. ;Secondary Objective: 1. Evaluation of clinical benefit and safety of use fludeoxyglucose (18F-FDG) in PET/CT imagening in juvenile patients with histiocytosis. 2. To determine the frequency of BRAF mutation in juvenile patients in Poland. 3. To determine the frequency of other mutations in juvenile patients in Poland. 4. To determine the rate of occurrence of mutations in ctDNA at different parts of treatment and follow-up. 5. To evaluate the diagnostic usefulness of the occurrence of mutations in ctDNA as a prognostic factor compared with other recognized factors. 6. Establishing of an immortalized cell line.;Primary end point(s): EFS – (event-free survival). ;Timepoint(s) of evaluation of this end point: Interim analyzes were planned after the enrollment of 50 patients. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary endpoints: • PFS (Progression-Free Survival), • OS (Overall Survival), • ORR (Overall Response Rate), • Reactivation rate after 2 years, • Molecular relapse, • Time to negative mutation test results (in ctDNA), • Cell line measurements. Endpoints related to safety: • Rate of participants presenting with Adverse Events separated by degree of intensity, category, affected organ or system.;Timepoint(s) of evaluation of this end point: Interim analyzes were planned after the enrollment of 50 patients. | — |
