Brief summary in lay language

Standard therapy response assessment of malignant melanoma (Stage IV) patients did not respect different modes of action of new therapies such as antibodies. In particular imaging of immune responses to tumors is difficult. New molecular imaging methods may solve this problem. They are able to indicate different tumor characteristics during one examination step. Depending on individual tumor characteristics they may respond either rather quickly or not at all to immunotherapy. Thus, it should be possible to differentiate rather quickly between responding and non-responding patients. The aim of the study is to evaluate if combined positronemission/magnetic resonance tomography (PET/MR) has the potential to detect responders already two weeks after immunotherapy initiation. A very early re-staging and therapy adjustment would have significant consequences for the individual clinical course: in case of non-responders an early switch to a maybe more effective therapy as well as the prevention of side-effects by noneffective therapies. The aim of the trial is to test multiparametric PET/MR imaging for early therapy response assessment at an early time point (two weeks after treatment initiation) in comparison to the regular response interval after twelve weeks in melanoma patients (without therapy modification).

Brief summary in scientific language

BRAF/MEK inhibitors and anti-CTLA-4/Anti-PD-1 antibodies in melanoma treatment go frequently along with harmful side effects. Treatment costs may cause relevant medical expenditures per month. Currently, therapy response assessment is performed using RECIST criteria which are based on changes in tumour size. PET/CT combines morphological and metabolic information. Thus, the so-called PERCIST-criteria were introduced integrating change in size and glucose utilization for response assessment. These new agents introduce different response patterns. In conventional chemotherapies, re-staging is usually performed 3 months after treatment initiation which is the result of empirical investigations. Moreover, it has recently been shown, that response to new targeted therapies can be detected much earlier using PET or functional MR techniques. This forms the rationale for the monitoring of melanoma patients using a combined PET/MR technique after only 2 weeks of therapy initiation. Especially for patients in stage IV with a medium survival time of 12 months, a 2.5 months earlier re-staging and therapy adjustment would have significant consequences for the individual clinical course.

Interventions, Observational Groups

Arm 1:
PET/MR examination of melanoma patients (Stage IV) at timepoints of therapy initiation (t0), as well as 2 weeks (t1) and 12 weeks (t2) after therapy start.

Endpoints

Primary outcome:
Comparison of patient's treatment response rate as assessed by PET/MRI acquired two weeks and three months after therapy initiation using standard response criteria (RECIST, PERCIST).
Secondary outcome:
-Testing the prognostic capacity of morphological and functional MR measures (diffusion, perfusion) for predicting the concordance of therapy response results two weeks and three months after treatment initiation. -Definition of PET/MRI-specific criteria for therapy response evaluation with respect to the personalized treatment approach, e.g. mode of action of “biologicals” (kinase inhibitor and therapeutical antibodies). -Validation of the significance and prognostic value of the defined PET/MRI-specific response evaluation criteria by correlation with TTP and OS.
