The primary trial objective is to see if the study drug called BI 907828 may help people with dedifferentiated liposarcoma (DDLPS) and is better than the approved drug, doxorubicin.
Additional trial goals are to find an optimal dose of BI 907828
and to determine whether BI 907828 improves the response
rate, duration of response, overall survival, disease control rate, the tolerability and if the study drug has a positive impact on the quality of life, compared to doxorubicin.
This study is for patients that have been diagnosed with stage III-IV Melanoma after a complete resection (no evidence of disease). The investigational drug in this study is relatlimab in combination with nivolumab. Investigational means the drug is not approved by the United States Food and Drug Administration (US FDA). Participants will be assigned to receive relatlimab with nivolumab in a fixed dose combination (FDC, both drugs in a single vial) or nivolumab alone, administered by intravenous (IV) infusion, meaning the drug is a solution given through a vein. The infusion is planned to take 30 minutes. Neither the participants or study doctor will know what is being administered.
This study is designed to explore if treating stage III-IV resectable melanoma patients with this combination, after they have surgery to remove all tumors, will reduce the probability of having progressive disease when compared to nivolumab alone, as well as to assess the possible side effects that this combination therapy might have. Participants can expect to be on this study for a minimum of 6 years.
