STUDY OBJECTIVES
Primary:
The primary objective is to compare the treatment groups in terms
of progression free survival (PFS) according to Recist v1.1 criteria.
Secondary:
•Overall survival (OS)
•Radiological response rate (in patients with measurable disease)
•Duration of response
•CA-125 response rate per GCIG
•Toxicity profile
• Quality of life using the EORTC C30 and EORTC 0V28

MITO-23: TRANSLATIONAL STUDIES
• Evaluating the impact of altered gene and microRNA
(miRNA) expression on trabectedin efficacy with the
aim of identify which genes are involved in the so
called BRCAness phenotype;
• Analysis of cellular infiltrate present on tumor
specimens of patients treated with trabectedin;
• DNA sequencing in order to evaluate
mutation/genetic aberration profile in selected panels
of genes associated to tumor sensibility to trabectedin
(BROCA panel).
MITO - 23
TRANSLATIONAL STUDIES:
Specimens
Tumor histological blocks (FFPE material): samples will be collected at primary surgery
and/or interval debulking surgery (or before trabectedin treatment by dedicated biopsies).
Storage and analysis will be centralized at Fondazione Istituto Nazionale dei Tumori.
•Characterization of tumor infiltrate by IHC (2 slides per marker & 1 HE slide & 3 backup
slides);
•Extraction of RNA from tissue sections for gene expression by DASL microarray analysis;
•Extraction of DNA from tissue sections for targeted sequencing of “Panel cancer related
genes” (in collaboration with Istituto Mario Negri, Milan).
Blood samples: Blood samples will be collected at baseline (registration), at third cycle of
treatment and at progression. Storage and analyses will be centralized at Istituto Mario Negri,
Milan. 10 ml blood sample will be taken at each time point, centrifuged in EDTA, processed to
obtain 5 ml plasma collected and stored at -20°C or at -80°C when possible.
•Analysis of miRNA profile by Agilen microarrays or evaluation of selected miRNA by RT-qPCR
(in collaboration with Fondazione Istituto Nazionale dei Tumori)
