Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be recruited to one of two cohorts based on the results of the pre-screening tissue testing:
Cohort 1: Cyclin E1 over-expressed and amplified; or
Cohort 2: Cyclin E1 over-expressed and non-amplified
Cohort 3: Cyclin E1 over-expressed treated with ceralasertib

Cohort 1 & 2: Patients will receive 300mg of adavosertib in the form of a daily oral tablet to be taken on Days 1-5 and then Days 8-12 of each 21-day cycle, for a maximum duration of 24 months (based on clinical response at the discretion of the investigator). Adherence to the intervention is recorded through to use of patient diaries that are to be brought to each of the patient's clinic visits (every 21 days while receiving adavosertib) along with any unused drug tablets remaining for that cycle also being brought to clinic.

Cohort 3: Ceralasertib will be administered orally 160 mg twice daily, starting on Day 1 until Day 14, in each 28 day treatment cycle, for a maximum duration of 24 months (based on clinical response at the discretion of the investigator). Adherence to the intervention is recorded through to use of patient diaries that are to be brought to each of the patient's clinic visits along with any unused drug tablets remaining for that cycle also being brought to clinic.

Statistical methods / analysis
Cohort 1 & 2:
Simon's two-stage design (Simon, 1989) will be implemented separately for each cohort: CCNE1 over-expressed and amplified and CCNE1 over-expressed and non-amplified. The null hypothesis that the true clinical benefit rate is 5% will be tested against a one-sided alternative. In the first stage, 10 patients will be accrued to each cohort. If there are no patients with clinical benefit in these 10 patients, no further patients will be recruited to that cohort. Otherwise, 19 additional patients will be accrued for that cohort for a total of 29. This design yields a type I error rate of 0.05 and power of 0.8 when the true clinical benefit rate is 20%.
A drop-out rate of up to 10% is expected; therefore, we aim to recruit a total of 32 patients in each cohort.
An additional 32 patients will be recruited to the non-amplified cohort (i.e. 64 non-amplified and 32 amplified patients will be recruited in total).

Cohort 3:
An optimal Simon's two-stage design (Simon, 1989) will be implemented for Cohort 3 – ceralasertib treated patients. The null hypothesis that the true 16 week overall response rate is 5% will be tested against a one-sided alternative hypothesis. In the first stage, 10 patients will be accrued. If there are no responders in these 10 patients evaluable for 16 week overall response rate, no further patients will be recruited to that cohort. Otherwise, 19 additional patients will be accrued for that cohort for a total of 29. This design yields a type I error rate of 0.05 and power of 0.8 when the true overall response rate is 20%.

Summary
Brief summary
This study will determine if the use of adavosertib (cohort 1 & 2) or ceralasertib (cohort 3) as monotherapy provides clinical benefit to patients with high grade serous ovarian cancer

Who is it for?
You may be eligible to join this study if you are aged 18 and above and have platinum resistant high grade serous ovarian cancer with Cyclin E1 over-expression

Study details
Participants in this study are now being enrolled into an additional third cohort.
Cohort 1 and 2 enrolled 71 participants with Cyclin E1 over-expression (Non-amplified or Amplified). who received the same intervention: daily oral adavosertib tablet from Day 1-5 and Day 8-12 of a 21-day cycle for a maximum of 24 months.
Cohort 3 plans to enrol 32 participants with Cyclin E1 over-expression (Non-amplified or Amplified). Participants will receive twice daily oral ceralasertib tablets from day 1-14 of a 28 day cycle for a maximum of 24 months.
Patients will undergo 4-weekly appointments for their treatment duration, have bloods taken for translational research and may also be required to have a biopsy performed after the end of their first cycle. All participants will be monitored regularly in order to assess clinical response and treatment safety.

It is hoped that IGNITE will provide clinical benefit to patients with high grade serous ovarian cancer who have Cyclin E1 expression and will be able to provide a new treatment option for patients with this genetic fault.
