Description of intervention(s) / exposure
As part of the main study, patients will initially undergo certain tests and scans to make sure that the study is right for them. During this time, three extra 10ml tubes of blood (30ml, 6-8 teaspoons) will be taken for this sub-study. During routine blood tests before each cycle of chemotherapy and maintenance phase of the GSK2110183 drug (see main study details below), an extra 30mls of blood will be collected. At the end of the study, a final 30mls of blood will also be collected.

Patients will also be asked to have a biopsy of their tumour before starting treatment (chemotherapy) and during treatment. The biopsies will give the researchers information about how the drug works and help to develop tests that predict who might respond to treatment. The tests involve looking at the molecules in the tumour tissue. Biopsies will be done only if it is easy to perform with minimal discomfort to participants. This will be done as a day case at the hospital after using a local numbing medicine to allow painless biopsy from the area by an experienced radiologist. The second biopsy is optional.

Addditionally, at any point during the study, should a participant require a clinical procedure to remove fluid from their abdomen, researchers would like to store some of the fluid which would otherwise be disposed of.

Timepoint [1] 300362 0
1) Compare changes in AKT, pAKT, PRAS40, pPRAS40, Ki67, LARP1 by IHC in tumour tissue before and after 1 cycle of treatment with GSK2110183 plus chemotherapy.
2) Compare changes in expression of other components of the extended AKT pathway by reverse phase protein array (RPPA) in tumour tissue before and after 1 cycle of treatment with GSK2110183 plus chemotherapy.
3) To correlate, where possible, with markers identified by IHC from archival tumour samples.
Secondary outcome [2] 300363 0
To correlate tumour mutational profiles with patient outcome in terms of clinical response
Timepoint [2] 300363 0
To determine pre- treatment biopsy tumour mutation profiles of known cancer genes by Sequenom OncoMap assays and correlate with patient outcome in terms of best RECIST (1.1) response, Overall Response, CA125 response and PFS. To correlate, where possible, with mutations identified in archival tumour samples
Secondary outcome [3] 300364 0
To correlate change in blood derived markers before and after treatment with pharmacodynamic measures (described above) and with patient outcome
Timepoint [3] 300364 0
To correlate levels of blood derived markers (such as circulating tumour cells, PBMCs for germline DNA and RPPA analysis and plasma LARP1 by ELISA) obtained during treatment to those at baseline with protein or genomic changes identified above and also with patient outcome (RECIST 1.1) in terms of best RECIST (1.1) response, Overall Response, CA125 response and PFS.

Summary
Brief summary
This is a biological study, which aims to answer novel questions about the molecular status of cells from patients with platinum-resistant ovarian cancer before and after treatment with the AKT inhibitor GSK2110183 given in combination with chemotherapy (in the accompanying PKB116611 study). We will biopsy tumour tissue and collect blood samples from PKB116611 participants with platinum resistant ovarian cancer prior to and following treatment in order to perform the following studies on tissue samples:

1) Immunohistochemical, ELISA and protein array (RPPA) based analysis of tumour biopsies for markers such as AKT, pAKT, PRAS40, pPRAS40, Ki67, LARP1 and multiple components of the extended AKT pathway
2) Genomic analysis of archived tumour samples for mutations in known cancer genes by Sequenom OncoMap assays.
3) Analysis of blood-derived markers in circulating tumour cells (CTCs), peripheral blood mononuclear cells (PBMCs) and plasma.
4) Analysis (where appropriate) of ascites (or pleural effusion) for markers such as AKT, pAKT, PRAS40, pPRAS40, Ki67 and LARP1.
