Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.

Outcomes
Primary outcome [1] 288511 0
To correlate pharmacodynamic evidence of AKT pathway inhibition with therapeutic outcome in patients with platinum resistant ovarian cancer receiving GSK2110183 plus combination chemotherapy.
Timepoint [1] 288511 0
ELISA-detected decrease in phosphorylated PRAS40 (as ratio of total PRAS40) and increase in pAKT S473 (as a ratio of total AKT) in available tumour samples before and after 1 cycle of treatment with GSK2110183 plus chemotherapy compared to best response to study treatment (RECIST 1.1), Overall Response, CA125 response and PFS
Secondary outcome [1] 300362 0
To compare changes to the proteomic and immunohistochemical profile of the extended AKT pathway with response and PFS using tumour tissue taken before and following one cycle of trial therapy with GSK2110183 plus combination chemotherapy.
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.
