Clinical trials

The goal of this clinical trial is to investigate the safety and feasibility of neoadjuvant immunotherapy for patients with high-risk uveal melanoma. The main question is: \- Is neoadjuvant treatment with nivolumab and ipilimumab safe and feasible for patientt with high-riks uveal melanoma? In addition pathological response, distant metastases-free survival, overall survival and immunological changes in the tumor microenviroenment after therapy will be assesed.

The primary objective of this Phase 1 clinical trial is to evaluate the feasibility and tolerability of a novel generation of gene-modified tumor infiltrating lymphocytes (TILs) in a cohort of 10 patients aged 18-75 diagnosed with unresectable or metastatic melanoma. TILs will undergo transduction with the Interleukin-7 (IL-7) gene, for IL-7 production upon antigen engagement. Participants will undergo: * screening * tumor operation following autologous TIL production (incl. transduction) - takes approximately 4-6 weeks * admission for lymphodepleting chemotherapy (Cyclophosphamide and Fludarabine phosphate), TIL infusion and high-dose IL-2 infusions for a maximum of 6 doses * Following treatment, patients will undergo systematic and regularly planned assessments, encompassing clinical evaluation, biochemistry analyses, and PET/CT scans. This thorough follow-up regimen will be continued until any of the following events occur: progressive disease, withdrawal from study, or end of study, which spans a duration of 15 years for trials involving genetically modified organisms.

The purpose of this study is to assess wether it is safe and feasible to treat patients with tumor infiltrating lymphocytes that have been silenced for PD-1, using CRISPR-Cas9.

This clinical trial is to clarify whether treatment with a checkpoint inhibitor alone (pembrolizumab) or two in combination (ipilimumab and nivolumab), results in clinical benefit for MM patients with brain metastases and in need of steroid treatment. Patients will be treated in four arms depending on steroid dose level at inclusion (\> 10 \< 25 mg prednisolone or \> 25 mg prednisolone) and treatment (pembrolizumab alone or the combination of ipilimumab and nivolumab).
