General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study is to determine whether abiraterone has clinical activity (objective response rate assessed by imaging and/or CA125 tumour marker changes in the blood) in patients with epithelial ovarian cancer (EOC) that has relapsed within 12 months of last treatment.
26 patients 'unselected' for androgen receptor (AR) status will be treated in stage one and, if successful, a further 21 patients in stage two bringing the total number of patients required to 47.
|
||
Protection of trial subjects |
Patients were provided with full verbal and written informed consent regarding the purpose and procedures of the trial and the possible risks involved. A patient information sheet and consent form were provided and patients were given sufficient time to consider their participation. The Principal Investigator at each site was responsible for ensuring written informed consent was obtained for each patient.
Full details of the trial medication and its safety profile were provided in the patient information sheet. Patients had the opportunity to discuss any concerns they had in relation to this with their study team at site.
|
||
Background therapy |
All patients received prednisone or prednisolone (at clinician's discretion) at 5mg orally once daily to prevent secondary mineralocorticoid excess. | ||
Evidence for comparator |
This was a two-stage phase II, non-randomised clinical trial with all patients receiving abiraterone once a day on a continuous 28-day cycle until disease progression. | ||

Stage 1

Stage 1 includes the first 26 patients recruited to the CORAL trial regardless of evaluability of the patient.

Evaluable
|
||
Subject analysis set type |
Per protocol | ||
Subject analysis set description |
Any patient who had a scan at 12 weeks and/or progressed/died prior to 12 weeks is considered evaluable and will be included in the analysis of the evaluable population. Any patient discontinuing the trial for other reasons prior to 12 weeks would not be considered evaluable.

End point title |
Objective response [1] | ||||||||||||||||||||
End point description |
Primary endpoint is objective response rate at 12 weeks after registration. Objective response is defined as a complete or partial response according to joint RECIST/GCIG criteria.

End point type |
Primary
|
||||||||||||||||||||
End point timeframe |
Up to 12 weeks from trial entry.

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: This is a single arm study and no comparative analysis was performed, however the system expects at least 2 groups to be identified. All methods and options specified in the analysis section apply to statistical methods and summary measures to report and compare at least 2 independent groups, which is not the case in this single arm trial. There is no way of reporting one group inference and summary values without triggering an error or reporting inaccurate information. |
