Retroperitoneal Leiomyosarcoma clinical trials

Trial of Nilotinib and Adriamycin as Treatment in Liposarcomas and Leiomyosarcomas of Retroperitoneum

Phase I/II multicenter and prospective trial of nilotinib and adriamycin as neoadjuvant treatment in liposarcomas and leiomyosarcomas of retroperitoneum. The main objective of this study is to improve relapse-free survival (RFS)and overall survival (OS) decreasing from 50% to 30% the relapse percentage at 5 years in patients with resected sarcoma of retroperitoneum. Secondary objectives include the analysis of antitumoral activity through response rate (RECIST and tissular changes), the assessment of positive correlation between biomarkers and clinical results, the study of long term overall survival, and the analysis of the safety profile of the nilotinib-adriamycin combination. The trial hypothesis is that the nilotinib-adriamycin combination is synergistic and therefore better response results are expected (from 20% as P0 to 40% as P1). The study seeks to find a positive correlation between biomarkers and clinical results in retroperitoneal liposarcoma and leiomyosarcoma treated with the mentioned combination. The study involves the participation of 20 hospitals of the Spanish Sarcoma Group (GEIS). The treatment consists of 4 neoadjuvant cycles of nilotinib-adriamycin on patients with resectable retroperitoneal sarcoma. The research comprises a robust translational study as well as histological and radiological reviews.
