Our lab aims to improve treatments for women with ovarian cancer, particularly those that are resistant to chemotherapy. We are interested in developing therapies that can adapt to the evolution of chemotherapy resistance over time. We also use drug repurposing approaches to specifically target chemotherapy-resistant ovarian cancers and to improve the therapeutic benefit of oncolytic viral therapies.

High grade serous cancer (HGSC) is the most common subtype of ovarian cancer. It is initially very responsive to platinum and taxane chemotherapy but more than 70% patients develop chemotherapy resistance and the disease becomes incurable.
Circumventing resistance is therefore a major unmet clinical need. The Lockley lab has created a panel of chemotherapy resistant HGSC cell lines and are using these to identify novel treatments for chemoresistant disease.
We aim to improve the utility of oncolytic viruses, whose clinical potential has so far been limited by inflammatory toxicity induced when they are administered systemically.
We showed for the first time that these inflammatory toxicities can be reduced by inhibition of β3 integrin, a cell surface signalling and adhesion protein, without compromising anticancer activity.
We now aim to further improve viral anti-cancer efficacy through combination with immune-modulatory therapies.
I set up and continue to lead the Barts Gynae Tissue Bank, This repository of tissue kindly donated by Barts patients is widely used by scientists at the BCI and elsewhere. It is the basis of the ERC funded CanBuild project lead by Prof Balkwill, which is creating innovative and accurate 3D models of the human omentum in high grade serous cancer.
I am Medical Adviser for this project.
