Date |
Amendment |

27 Apr 2018 |
The protocol was expanded to include a cohort of patients with somatic BRCA mutations (sBRCAm). |
||
22 Oct 2020 |
The contraceptive language was updated based on feedback from the Czech Republic regulatory authority. Myelodysplastic syndrome (MDS)/acute myeloid leukaemia (AML) were changed from important potential risks to important identified risks due to a change in risks related to olaparib. Clarification of post study access in the form of transition to a roll-over study (ROSY-O), continuous supply within this trial, or switching to commercial drug. |
||
19 Apr 2021 |
The second time point for statistical analysis has been extended to Q2/Q3 2021 due to longer than expected survival. Based on the current death event rate, at least~ 130 deaths ( ~52% maturity) are predicted to have occurred by this date. In order to reduce the burden on patients in terms of schedule of assessments, the follow-up after data cut-off (DCO) was reduced. Patients still receiving treatment with olaparib will have the option of continuing to receive olaparib as part of the roll over ROSY-O study (NCT04421963). Acceptable non-hormonal and hormonal birth control methods were updated following Investigator Brochure update. |

Interruptions (globally) |

Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Due to insufficient number of patients in sBRCA cohort, the outcome measures were not calculated. |
