Study information
Scientific title
AKTRES study: A Biologic Study of the early effects and determinants of AKT inhibition using GSK2110183 alongside chemotherapy in patients with platinum RESistant adenocarcinoma of the ovary
Acronym
AKTRES
Study hypothesis
Activation of the AKT signalling pathway in ovarian cancer cells causes chemotherapy resistance. An AKT inhibitor, given alongside chemotherapy, could potentially reverse this resistance and enable chemotherapy to be effective once again. This study is designed for women whose ovarian cancer has relapsed within 6 months of receiving carboplatin or cisplatin-containing chemotherapy and who are receiving an AKT inhibitor given alongside 3 weekly carboplatin and paclitaxel in the PKB116611 trial. Participants in the AKTRES study undergo a maximum of two biopsies from their tumour and some additional blood tests. The aims of the study are to better understand the how chemotherapy-resistant cancer cells are affected by AKT inhibitors.

Condition
Topic: National Cancer Research Network; Subtopic: Gynaecological Cancer; Disease: Ovary/Fallopian tube
Intervention
Blood sampling, [3x 10mls whole blood collected in greentopped (heparinised) tube] will be collected at baseline (within 14 days prior to first dose), on day 1 (immediately preceding chemotherapy), day 8 and day 15 of cycle 1 only. Blood sampling will subsequently be performed at day 1 only of subsequent chemotherapy treatment cycles and thereafter 3 weekly for those on maintenance GSK2110183 alone. A final 3 x 10mls blood sample will be taken at end of study visit.
Coagulation profile, will be collected immediately prior to the first biopsy during the screening period and postcycle 1 biopsy on day 22. This is in addition to the screening coagulation blood test required for PKB116611 study.
Collection of ascites: If patients are undergoing ascitic or pleural drainage for symptom relief prior to, or during, this study a sample of ascites (or pleural effusion) can be taken and stored. The preferred times for collection are during screening, day 22 and at study completion, but additional/alternative collections can be obtained at the investigators discretion.
Tumour Biopsy: A tumour biopsy performed under image guidance within 14 days prior to first dose. Three tumour cores will be taken, two will be fresh frozen and one will be formalin fixed. Following one complete treatment cycle (day 22), =3 days prior to starting cycle 2 day 1, a second tumour biopsy will be performed under image guidance. Again, three tumour cores will be taken, two will be fresh frozen and one will be formalin fixed. Patients can decline the second biopsy if they wish to.
