This study is being conducted in two parts, designated Parts A and B. Part A is a safety lead-in consisting of a cohort of approximately 12 patients with advanced solid tumours.~Part B expansion cohorts will investigate AZD1775 monotherapy in advanced tumour types with molecular biomarkers of interest. The tumour types to be evaluated are: 1) ovarian cancer (BRCA1/2 mutation [PARP-failures]), 2) ovarian cancer (BRCA wild-type) with more than three prior lines of treatment, 3) triple negative breast cancer (TNBC), and 4) small-cell lung cancer (SCLC).
This is an open-label, multi-centre, Phase Ib study of AZD1775 designed to assess the safety, tolerability, pharmacokinetics, and anti-tumour activity of AZD1775 monotherapy in patients with advanced solid tumours.
