Effect of prexasertib on disease progression and survival in High grade serous ovarian cancer patients

The goal of this study was to compare transcription profiles of high grade serous ovarian cancer (HGSOC) patients at Day 0 and Day 15 of a single course Prexasertib treatment at 105mg/m2 intravenously over 1 hour. HGSOC patients recruited for this study were women aged 18 and older with most (79%) showing platinum resistant or refractory disease. Total RNA from patients before (Day 0, n=18) and 2 weeks after Prexasertib treatment (Day15, n=11) were prepared from frozen biopsies, and analysed using HiSeq4000 using Illumina TruSeq Stranded Total RNA Library Prep and paired-end sequencing. Data is shown as quartile normalized CPM-TMM values. Patient survival and response was monitored till end of study. Our study show that prexasertib has clinical benefit in HGSOC patients.
