Brief summary
This study is to assess the efficacy and safety of olaparib monotherapy versus olaparib in combination with an inhibitor of ATR (Ataxia-Telangiectasia Mutated (ATM) and Rad3-related protein kinase (Ceralasertib \[AZD6738\]) and olaparib monotherapy versus olaparib in combination with an inhibitor of WEE1 (adavosertib \[AZD1775\]) in second or third line setting in patients with Triple-negative breast cancer (TNBC) prospectively stratified by presence/absence of qualifying tumour mutation in genes involved in the homologous recombination repair (HRR) pathway. Treatment arms are olaparib monotherapy, olaparib+ Ceralasertib and olaparib+adavosertib. The study subject population will be divided into Stratum A, Stratum B, and Stratum C. Due to the different schedules of administration of each of the treatment options as well as their different toxicity profiles, the study is not blinded. Study has two stage consent process- stage 1 consent (molecular screening for HRR defects) and stage 2 consent (main study). Patients with TNBC and with known qualifying BRCAm, non BRCAm HRRm and non HRRm status will be offered the option of consenting to the main part of the study within the 28-day screening period. Following the ISRC meeting on 17 April 2019 a recommendation was made to close the adavosertib+olaparib treatment arm across all biomarker strata. Patients receiving treatment with adavosertib+olaparib treatment were offered the opportunity to continue treatment on olaparib monotherapy at the approved dose (300 mg bd). Following the closure of this arm the total number of patients randomised will be lower (approximately 350 patients). Approximately 300 patients will be randomised (using randomisation ratio 1:1) to 2 ongoing treatment arms plus an additional 47 patients to a 3rd arm (olaparib+adavosertib) prior to the arm being discontinued.
Detailed description
This is a prospective, open label, randomised, multi-centre Phase 2 study that will assess the efficacy and safety of olaparib monotherapy versus olaparib in combination with an inhibitor of ATR (Ceralasertib) and olaparib monotherapy versus olaparib in combination with an inhibitor of WEE1 (adavosertib) in second or third line setting in patients with TNBC prospectively stratified by presence/absence of qualifying tumour mutation in genes involved in the HRR pathway. Eligible patients will be randomised by a ratio 1:1:1 to treatment Arm 1: olaparib continuous in a 28-day cycle, Arm 2: Ceralasertib Days 1-7 with olaparib continuous in a 28-day cycle or Arm 3: adavosertib Days 1-3 and 8-10 with olaparib continuous in a 21-day cycle. Following the ISRC meeting on 17 April 2019 a recommendation was made to close the adavosertib+olaparib treatment arm across all biomarker strata. Following closure of this arm the randomisation ratio will be 1:1 to olaparib monotherapy or Ceralasertib+olaparib. Patients who were receiving treatment with adavosertib+olaparib treatment were offered the opportunity to continue treatment on olaparib monotherapy at the approved dose (300 mg bd). The study subject population will be divided into Stratum A (patients with mutations in BRCA1 or BRCA2 (Breast cancer susceptible gene mutation (BRCAm)), Stratum B (patients with mutations in any of the other genes involved in the HRR pathway and no mutation in BRCA1 and no mutation in BRCA2), and Stratum C (patients with no detected tumour mutations in any of the HRR genes). Within each stratum A, B and C, there will be further stratification by whether the patient received prior platinum-based therapy. In the olaparib monotherapy treatment arm as well as in the Ceralasertib+olaparib treatment arm, patients will be administered olaparib bd at 300 mg continuously. Two (2) 150 mg olaparib tablets will be taken at the same time each day, approximately 12 hours apart with one glass of water (approximately 250 mL). In the adavosertib+olaparib treatment arm, patients will be given olaparib 200 mg bd (2 x 100 mg tablets twice a day) and adavosertib 150 mg bd from Day 1 to Day 3 (inclusive) and Day 8 to Day 10 (inclusive) of every 21-day cycle. Ceralasertib will be supplied as 20 mg, 80 mg, or 100 mg film coated tablets. Patients will be administered Ceralasertib od at 160 mg from Day 1 to Day 7 (inclusive) of every 28-day cycle. A total of 160 mg of Ceralasertib tablets will be taken at the same time on each day of dosing with approximately 250 mL of water. Adavosertib will be supplied as capsules containing 25 mg, 50 mg, 75 mg, 100 mg, or 200 mg of drug substance. Adavosertib will be taken with approximately 250 mL of water approximately 2 hours before or 2 hours after food. Olaparib, Ceralasertib and adavosertib will be provided by AstraZeneca. Primary outcome measures (progression free survival \[PFS\]) will be analysed for the 3 patient populations BRCAm, Non BRCAm HRRm (Homologous Recombination Repair gene mutation) and Non HRRm. Secondary outcome measures will be analysed in 2 patient populations HRRm and All for PFS, Objective response rate (ORR) and overall survival (OS) will be analysed in all 5 patient populations. DoR, and tumour change will be analysed in BRCAm, Non BRCAm HRRm, and Non HRRm patient populations. Tumour and germline mutation status will be analysed only in the all patient population. PK outcome measures will be analysed only in the all patient population. Blinded Independent Central Review (BICR) of radiological imaging data will be carried out using RECIST version 1.1 and Investigator assessments will also be analysed for sensitivity purposes.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free Survival Per Stratum (BICR) | Until date of first documented progression or censoring date or date of death from any cause, whichever came first (assessed up to 32 months) | Progression-free survival was defined as time from randomization until the date of objective disease progression or death, regardless of whether the patient withdrew from randomized therapy or received another anti-cancer therapy prior to progression. Progression was determined by Blinded independent central review (BICR) using Response Evaluation Criteria In Solid Tumours Version (RECIST 1.1). Patients who had not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST assessment. If patients had no evaluable visits or baseline data, the patient was censored at Study Day 1, unless death occurred within 17 weeks i.e., death within 17 weeks was relative to randomization. Here, the study patient population was stratified as follows: Breast cancer susceptible gene mutation (BRCAm) patients; non BRCAm homologous recombination repair gene mutation (HRRm) patients; non HRRm patients. |
| Progression-free Survival Per Stratum (Sensitivity Analysis) | Until date of first documented progression or censoring date or date of death from any cause, whichever came first (assessed up to 32 months) | Progression-free survival was defined as time from randomization until the date of objective disease progression or death, regardless of whether the patient withdrew from randomized therapy or received another anti-cancer therapy prior to progression. Progression was determined by the site Investigator. Patients who had not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST 1.1 assessment. If patients had no evaluable visits or baseline data, the patient was censored at Study Day 1, unless death occurred within 17 weeks i.e., death within 17 weeks was relative to randomization. Here, the study patient population was stratified as follows: BRCAm patients; non BRCAm HRRm patients; non HRRm patients. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Patients With Objective Response (Per BICR and Per Sensitivity Analysis) | From date of randomization until date of first documented progression or last evaluable assessment, or start of subsequent anti-cancer therapy (Whichever occurred first [assessed up to 32 months]) | The objective response was defined as patients with at least one BICR assessed visit response of CR or PR. For sensitivity analysis, objective response was defined as the patients with at least one visit response of CR or PR based on Investigator data. These are unadjusted percentages of responders (100 \* number of responders / number of patients in full analysis set). The objective response was assessed per RECIST 1.1 guidelines for: measurable lesions (measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) using CT or MRI, non-measurable lesions (all other lesions, including small lesions (longest diameter \<10 mm or pathological lymph nodes with ≥10 to \<15mm short axis at baseline), based on target lesions \[TL\] (maximum of 5 measurable lesions (with a maximum of 2 lesions per organ), non-target lesions \[NTL\] (lesions (or sites of disease) not recorded as TL should be identified as NTL at baseline) and any new lesions. |
| Objective Response Rate (ORR) (Per BICR and Per Sensitivity Analysis) | From date of randomization until date of first documented progression or last evaluable assessment, or start of subsequent anti-cancer therapy (Whichever occurred first [assessed up to 32 months]) | The ORR was defined using BICR data to define a visit response of CR or PR, with denominator defined as number of patients in FAS. For sensitivity analysis, ORR is defined as the percentage of patients with at least one investigator-assessed visit response of CR or PR, with denominator defined as number of patients in FAS. These are summarized using adjusted response rates, which are computed with a logistic regression including factors study treatment and prior platinum-based therapy (no, yes), i.e. these response rates are adjusted for prior platinum-based therapy, which is one of the randomisation stratification factors. The adjusted response rates have been presented as a percentage of patients. |
| Duration of Response (DoR) [Per BICR and Per Sensitivity Analysis] | From date of first documented response until date of first documented progression or last evaluable assessment (assessed up to 32 months) | The DoR was defined as the time from the date of first documented response according to BICR data until date of documented progression according to BICR data or death in the absence of disease progression. For sensitivity analysis, DoR was defined as the time from the date of first documented response according to Investigator assessment until date of documented progression according to Investigator assessment or death in the absence of disease progression. Here, the median DoR and the 25th and 75th percentile of DoR are presented. The DoR from onset of response was calculated using Kaplan-Meier technique. Here, the study patient population was stratified as follows: BRCAm patients; non BRCAm HRRm patients; non HRRm patients. |
| Percentage Change From Baseline in Target Lesion Tumour Size [Per BICR and Per Sensitivity Analysis] | Baseline, at Week 16 | Tumour size was the sum of the longest diameters of the target lesions (TLs). The percentage change in TL tumour size at Week 16 was obtained for each patient as follows (considering a visit window around the scheduled day of the Week 16 assessment): (TL at Week 16 minus TL at baseline) divided by (TL at baseline) multiplied by 100. Here, the percentage change data have been reported as per BICR and as per sensitivity analysis per investigator assessments. Here, the study patient population was stratified as follows: BRCAm patients; non BRCAm HRRm patients; non HRRm patients. |
| Overall Survival (OS) | From the date of randomisation until time of data cut-off date or death due to any cause (assessed up to 32 months) | Overall survival was defined as the time from the date of randomisation until death due to any cause. Any patient not known to have died at the time of data cut-off was censored based on the last recorded date on which the patient was known to be alive. Here, the study patient population was stratified as follows: BRCAm patients; non BRCAm HRRm patients; non HRRm patients. |
| Plasma Drug Concentrations of Olaparib | Pre-dose at Cycle 1 Day 7 [olaparib monotherapy or ceralasertib+olaparib] or Cycle 1 Day 10 [adavosertib+olaparib] (each cycle is 21 days for olaparib+adavosertib, and 28 days for olaparib monotherapy and olaparib+ceralasertib) | Plasma drug concentrations of olaparib are evaluated to assess exposure to olaparib in all patients. |
| Number of Patients With Treatment Emergent Adverse Events (TEAEs) | From screening until Follow-up 30 Days after last dose of study treatment (assessed up to 32 months) | Treatment-emergent adverse events reported after treatment with olaparib monotherapy, the combination of ceralasertib and olaparib or the combination of adavosertib and olaparib. The data includes adverse events (AEs) with an onset or worsening date on or after the date of first dose and up to and including 30 days following the date of last dose of study medication. |

Number of Patients With Objective Response (Per BICR and Per Sensitivity Analysis)
The objective response was defined as patients with at least one BICR assessed visit response of CR or PR. For sensitivity analysis, objective response was defined as the patients with at least one visit response of CR or PR based on Investigator data. These are unadjusted percentages of responders (100 \* number of responders / number of patients in full analysis set). The objective response was assessed per RECIST 1.1 guidelines for: measurable lesions (measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) using CT or MRI, non-measurable lesions (all other lesions, including small lesions (longest diameter \<10 mm or pathological lymph nodes with ≥10 to \<15mm short axis at baseline), based on target lesions \[TL\] (maximum of 5 measurable lesions (with a maximum of 2 lesions per organ), non-target lesions \[NTL\] (lesions (or sites of disease) not recorded as TL should be identified as NTL at baseline) and any new lesions.

Objective Response Rate (ORR) (Per BICR and Per Sensitivity Analysis)
The ORR was defined using BICR data to define a visit response of CR or PR, with denominator defined as number of patients in FAS. For sensitivity analysis, ORR is defined as the percentage of patients with at least one investigator-assessed visit response of CR or PR, with denominator defined as number of patients in FAS. These are summarized using adjusted response rates, which are computed with a logistic regression including factors study treatment and prior platinum-based therapy (no, yes), i.e. these response rates are adjusted for prior platinum-based therapy, which is one of the randomisation stratification factors. The adjusted response rates have been presented as a percentage of patients.

Progression-free survival was defined as time from randomization until the date of objective disease progression or death, regardless of whether the patient withdrew from randomized therapy or received another anti-cancer therapy prior to progression. Progression was determined by BICR using RECIST 1.1. Patients who had not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST assessment. If patients had no evaluable visits or baseline data, the patient was censored at Study Day 1, unless death occurred within 17 weeks i.e., death within 17 weeks was relative to randomization. Here, the study patient population was presented as follows: HRRm and all enrolled patients.
Time frame: From randomization until date of first documented progression or censoring date or date of death from any cause, whichever came first (assessed up to 32 months)
Population: All randomized patients were analyzed according to the randomization scheme, regardless of the treatment they actually received. Here, number analyzed reflects number of patients enrolled in each stratum per treatment arm.
