简要总结
Combination therapy is becoming more and more general in the treatment of oncological diseases. In this clinical trial combination the standard immunotherapeutic treatment; the programmed death 1 (PD-1) regulatory antibody Nivolumab and a peptide vaccine consisting of programmed death ligand 1 (PD-L1) and Indoleamine 2,3-dioxygenase (IDO) peptides will be tested in patients with metastatic melanoma. Patients will be treated with Nivolumab every second week as long as there is clinical benefit. The PD-L1/IDO peptide vaccine is given from start of Nivolumab and every second week for the first 6 vaccines and thereafter every fourth week up to 1 year.
详细描述
Background:
Huge advances have been made in the treatment of metastatic melanoma (MM) the past 5 years. Especially immunotherapy has shown promising results.
Cancer cells are naturally attacked by cells of the immune system, but can induce a state of tolerance whereby they escape from immune attack. This escape is brought about by many mechanisms. An important one is the programmed death pathway (PD-1/PD-L1). PD-L1 is commonly overexpressed on cancer cells. Interaction of PD-1 on activated T cells and PD-L1 on cancer cells lead to inhibition of the cytotoxic T cells. Another important mechanism is through overexpression of the metabolic enzyme IDO on cancer cells. Activation of IDO also inhibits cytotoxic T cells.
Investigators have recently identified spontaneous T cell reactivity against PD-L1 and IDO in the tumor microenvironment and in the peripheral blood of patients with MM and healthy donors. Both IDO and PD-L1 reactive CD8 T cells are cytotoxic and can kill cancer cells and immune regulatory cells in vitro.. Thus boosting specific T cells that recognize immune regulatory proteins such as IDO and PD-L1 may directly modulate immune regulation.
Due to distinct mechanisms of action, the combination of treatment with a monoclonal antibody targeting PD-1 (Nivolumab) and a vaccine with peptides against PD-L1 and IDO may have a synergistic effect.

研究组 & 干预措施
Patient group
All patients receive the same treatment. Patients included in the protocol are treated with Nivolumab according to usual guidelines, implying outpatient IV infusions of 3 mg/kg biweekly until progression.
The vaccine is administered on the same day as the administration start of Nivolumab. The vaccination is given biweekly for a total of 6 times, then every fourth week up to week 47, whereupon no additional vaccines will be given. In total, 15 vaccines will be administered. A vaccine consist of 100 μg IDO long peptide, 100 μg PD-L1 long1 peptide and 500 microliters Montanide as adjuvant.
Patients who complete all vaccines will continue Nivolumab treatment after standard guidelines.
