Brief Summary

Although immunotherapy has revolutionized the treatment of many cancers, ovarian cancer patients have not yet benefitted from the advances. In two consecutive pilot trials at National Center for Cancer Immune Therapy (CCIT-DK), is has been have shown that adoptive cell therapy (ACT) with TILs for patients with advanced ovarian cancer (OC) is feasible and tolerable. In the most recent of these trials ACT was combined with a CTLA-4 inhibitor, Ipilimumab and a PD1-inhibitor, Nivolumab. Only transient clinical responses where observed. Between 90-100 % of infused T-cells in our previous ovarian cancer ACT trial expressed LAG-3. The interaction between LAG-3 on T-cells and MHC-II on tumor cells inhibits T-cell function. In this study adding the LAG-3 antibody Relatlimab to the ACT-regimen described above may therefore well unleash T-cell antitumor efficacy by blocking the known LAG-3-MHC-II interaction. With this study the aim is to demonstrate that adding the lag-3-inhibitor Relatlimab to the above treatment regimen is feasible and tolerable. The study will elucidate whether the combination Relatlimab-Nivolumab leads to objective responses and improves progression free survival (PFS).

Study Arms (2)

Without Ipilimumab

OTHER

At Step 1, 6 patients will be treated without Ipilimumab pre tumor harvest. If feasible and tolerable, as defined by no additional SAE/SAR compared to the previously completed pilot studies at CCIT-DK, the trial will move to Step 2. Depending on the safety and feasibility on step 2, 6 more patients can be included at step 1.

Drug: CyclophosphamidDrug: Fludarabine PhosphateBiological: Tumor Infiltrating Lymphocytes infusionDrug: NivolumabDrug: Relatlimab

With Ipilimumab

OTHER

At Step 2, 6 patients will be included. Ipilimumab 3 mg/kg will be administered 2-6 weeks pre tumor harvest. If no additional SAE/SAR compared to the previous completed pilot study at CCIT-DK is observed additional 6 patients can be included at Step 2. If on the other hand Step 2is not found safe additional 6 patients can be included at Step 1

Interventions

Ipilimumab 3 mg/kg is administered 2-6 weeks before surgical removement of the tumor. The medicine is administered i.v. over 30 minutes.
