Description of intervention(s) / exposure
Participants will be randomised in the ratio of 2:1 between the Arms:

Arm 1: Carboplatin, paclitaxel combined with durvalumab and tremelimumab (Du-T-NACT), followed by maintenance durvalumab and tremelimumab
a) Carboplatin: AUC 5 via intravenous infusion on Day 1 of each 21 day cycle, for a total of 18 weeks
b) Paclitaxel: 175 mg/m2 via intravenous infusion on Day 1 of each 21 day cycle, for a total of 18 weeks
c) Durvalumab: 1500mg via intravenous infusion on Day 1 of each 21 day cycle, for a total of 36 weeks
d) Tremelimumab: 75mg via intravenous infusion on Day 1 of each 21 day cycle, for a total of 36 weeks

Following completion of 3 cycles of neoadjuvant treatment, patients in both arms who are suitable for interval debulking surgery (IDS) should undergo debulking surgery with the goal of optimal cytoreduction by a certified gynaecological oncologist. Surgery should be performed at least 21 days after cycle 3 day 1 (C3D22) but before day 36 (C3D36) provided adequate haematological and clinical recovery.

Patients in Arm 1 who continue to respond will receive maintenance therapy with durvalumab and tremelimumab. Maintenance treatment should commence 4 weeks ± 3 days following the last dose of adjuvant treatment in cycle 6 and continue for 36 weeks or until disease progression, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met. Maintenance immunotherapy will consist of:
a) Durvalumab: 1500mg via intravenous infusion on Day 1 of each 21 day cycle, for a total of 36 weeks
b) Tremelimumab: 75mg via intravenous infusion on Day 1 of each 21 day cycle, for a total of 36 weeks

Statistical methods / analysis
Baseline characteristics and treatment details will be described by Arm using descriptive statistics such as minimum, maximum, median, mean and standard deviation for quantitative variables. Qualitative variables will be described in tabular form as counts and percentages.

No imputation for missing values and no adjustment for multiplicity is intended.

The primary endpoint for this trial is the rate of CRS 3 after 3 cycles of neoadjuvant therapy. The CRS 3 rate will be reported as a binomial proportion with exact two-sided 90% confidence interval in the subset of patients treated with Du-T-NACT who underwent surgery (most patients are expected to have surgery). A second analysis of CRS rate will be performed considering all patients randomised to Du-T-NACT with patients not proceeding to surgery due to not responding to treatment being considered as non-responders for CRS 3.

A cut-off date for follow-up will be determined at the time of analysis, generally taken as the date of the earliest follow-up on all participants alive and not lost to follow-up. The cut-off date will be chosen to enable data on follow-up to that date to be collected, where possible, on all living participants. All events occurring after this date will be ignored in the analysis in order to minimise reporting bias. Progression free survival will be described for each Arm using Kaplan-Meier methods. Estimates at key time points will be provided with 95% confidence intervals. The stratified log-rank test will be used to compare the curves between Arms.

Pre-operative response rate, CA-125 response rate, CRS response rate and surgery completion rate will be estimated for each Arm with corresponding exact 95% confidence interval and will be compared between Arms using Fisher’s exact test. The surgery delay time will be described in each Arm using descriptive statistics.

All AEs observed from the beginning of treatment until 30 days after the last dose is administered will be recorded for each participant and the maximum AE grade per participant of each adverse event will be derived and presented in table format according to Arm. The analysis of AE’s will be conducted twice: once for all AE’s, regardless of relatedness to treatment and once considering only AE’s related to the treatment (i.e. classified as possibly, probably or definitely related). Rate of grade 3+ toxicities will be compared between Arms using Fisher’s exact test. Serious AEs and other significant AEs will be listed.

HRQoL will be analysed using linear mixed models (LMM) with time (as factor), Arm and interaction of time and Arm included as a fixed effect and patient included as a random effect. No within-group correlations will be assumed, with the model being fitted by maximizing the restricted log-likelihood (REML). No imputation for missing values is intended. Means and 95% confidence intervals will be estimated from the LMM contrasts for each Arm and each time point. HRQoL trajectory will be described graphically.

An analysis of measured biomarkers will be performed to assess association with disease activity, effects of study drug and clinical outcomes in order to detect potentially prognostics or predictive biomarkers that may be of interest for further research. Biomarkers analysis methods and report will be separate from the main study.

A statistical analysis plan (SAP) will be written for the trial. Any deviations from the planned analysis will be described in a protocol amendment or updated SAP.

The proposed primary endpoint is complete pathological response (CRS 3) after 3 cycles of neoadjuvant chemotherapy. The expected rate of CRS 3 from the primary and validation cohorts of chemotherapy response scoring was 27-33%. For patients treated with Du-T-NACT , the null hypothesis is that the true rate of CRS 3 is 30% and would be of no further interest, whereas a CRS 3 rate of greater than or equal 50% is of interest for further development. With 80% power, 0.05 alpha, 1-sided exact test, the required sample size of patients treated with Du-T-NACT is 43 patients. The primary endpoint will be assessed on patients who underwent surgery, therefore 50 patients will be recruited to allow at least 43 to be assessable for primary the endpoint.

A control group of 25 patients treated with NACT alone will be recruited to provide a contemporary estimate of the CRS 3 rate in this population. This will allow for further validation studies if the control group is found to have a CRS 3 rate higher than the expected 30%. Patients will be randomised at a 2:1 ratio between Du-T-NACT and NACT alone.

Recruitment of the 75 patients will occur over a two-year period and patients will be followed until 2 years after last participant commenced treatment

Summary
Brief summary
Ovarian cancer is the second most common gynaecological malignancy and the most common cause of gynaecological cancer death in Australia. The majority of women are diagnosed with advanced disease, where standard treatment includes surgery followed by six cycles of adjuvant platinum-based chemotherapy.

The purpose of this research project is to test how safe and effective the combination treatment of durvalumab and tremelimumab in combination with standard chemotherapy is as a treatment for patients with ovarian, fallopian tube or peritoneal cancers.

Who is it for?
You may be eligible to join this study if you are a female aged 18 years or older with a confirmed diagnosis of stage III or IV high grade serous ovarian, fallopian tube, or peritoneal carcinoma, and a life expectancy of at least 12 weeks.

Study details
Participants in this study will be randomly allocated (by chance) to one of two groups. Participants in one group will receive [18 weeks/6 cycles] of treatment with Carboplatin, paclitaxel combined with durvalumab and tremelimumab (Du-T-NACT) administered intravenously (i.e. directly into the vein). This will then be followed by maintenance therapy with Durvalumab (every 4 weeks) and Tremelimumab (every 12 weeks) for 36 weeks or until disease progression, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met. Durvalumab and tremelimumab are new drugs which are designed to increase the body’s immune response. Participants in the other group will receive [18 weeks/6 cycles] of chemotherapy with Carboplatin and paclitaxel only, followed by an observation period, which involves 4 weekly CA-125 assessments. Participants in both groups may also undergo interval debulking surgery after 3 cycles of treatment, if suitable.

All participants will be monitored regularly for up to 12 months post treatment in order to assess clinical response and treatment safety. It is hoped that that durvalumab and tremelimumab will stimulate the immune cells to be able to prevent or slow down cancer growth.

The study aims to recruit 75 patients (50 patients to receive adjuvant treatment and 25 to receive neoadjuvant treatment at a 2:1 ratio), across 10 Australian sites over a 2 year recruitment period.
