Brief Summary:

This is an international, multi-centre, non-controlled, open-label, single arm, two-stage Simon Design phase II study for non-BRCA metastatic breast cancer (MBC) patients with homologous recombination deficiency treated with Olaparib single agent.

The main objective is to assess the efficacy of olaparib single agent as determined by Clinical Benefit Rate (CBR) using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).

In the first stage Triple negative (TN) non-BRCA, metastatic breast cancer (MBC) patients whose tumours exhibited any characteristic related to homologous recombination deficiency (HRD). In the second stage, luminal patients (RH positive HER2 negative) will be allowed in the same conditions that TN.

Patients whose tumours are identified as Homologous Recombination Deficient by deleterious HRR gene mutations (according to Foundation Medicine's Foundation One assay) will receive olaparib 300 mg (two tablets of 150mg) orally twice daily (bid) on days 1-28 each 28 days.

Study commitment is 39 patients: 17 patients will be enrolled at first stage and 22 at the second stage.

The total duration of the study period is 34 months.

Detailed Description:

This is an international, multi-centre, non-controlled, open-label, single arm, two-stage Simon Design phase II study for non-BRCA metastatic breast cancer (MBC) patients with homologous recombination deficiency treated with Olaparib single agent.

The main objective is to assess the efficacy of olaparib single agent as determined by Clinical Benefit Rate (CBR) using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).

Triple negative non-BRCA metastatic breast cancer women (for the first stage) age ≥ 18 years that had previously received at least one (and no more than three) line for their metastatic disease. Patients must have previously received taxanes either in the early or in the metastatic scenario. To be included in the trial, tumours must be considered homologous recombination deficient (HRD) according to Foundation Medicine's Foundation One assay. Evidence of measurable metastatic disease is required.

In the second stage, luminal patients (RH positive HER2 negative) will be allowed to participate in the same conditions that TN patients.

Patients whose tumours are identified as Homologous Recombination Deficient by deleterious HRR gene mutations (according to Foundation Medicine's Foundation One assay) will receive olaparib 300 mg (two tablets of 150mg) orally twice daily (bid) on days 1-28 each 28 days.

Study commitment is 39 patients: 17 patients will be enrolled at first stage and 22 at the second stage.

During the period between the end of the first stage and the beginning of the second, an interim analysis will be conducted to assess the viability of the second part of the trial.

The total duration of the study period is 34 months.

Stage I:

  • Recruitment period: 10 months
  • Follow-up period: Up to 6 months after last patient included in the study

Stage II:

  • Recruitment period: 12 months
  • Follow-up period: up to 6 months after last patient included in the study

Primary Outcome Measures :
  1. To assess the efficacy of olaparib single agent in non-BRCA MBC patients whose tumours exhibit an homologous recombination deficiency (HRD) signature, as determined by Clinical Benefit Rate (CBR) using RECIST 1.1 criteria [ Time Frame: Baseline up to 24 weeks ]
    The CBR as best response, defined as the percentage of patients who experience a complete response, partial response or stable disease for at least 24 weeks and assessed by modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) criteria


Secondary Outcome Measures :
  1. To assess the accuracy of Foundation One's HRR assay in predicting the proportion of patients with response to olaparib. [ Time Frame: Baseline up to 34 months ]
    The positive predictive value (PPV) of the signature to predict patients that achieved objective response and clinical benefit.

  2. To assess incidence of Treatment-Emergent Adverse Events (Safety profile) of olaparib in this population [ Time Frame: Baseline up to 34 months ]
    This study will consider the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE v4.03 criteria) grade 3 and 4 events (AEs) and serious AEs (SAEs) in order to assess the safety and tolerability objectives.

  3. To investigate the prevalence of HRD signature within triple negative and luminal non-BRCA patients' cohorts [ Time Frame: Baseline up to 34 months ]
    The percentage of patients with HRD according to the Foundation Medicine's Foundation One assay within triple negative and luminal (in the second stage) non-BRCA patients' cohorts

  4. To explore the efficacy of olaparib in terms of Progression-free survival (PFS) [ Time Frame: Baseline up to 34 months ]
    The PFS defined as the time from the first dose of study drugs until objective tumour progression or death, as assessed by the investigator per RECIST v1.1.

  5. To explore the efficacy of olaparib in terms of objective response rate (ORR) [ Time Frame: Baseline up to 34 months ]
    The ORR defined as the proportion of patients with best objective response of confirmed complete response (CR) or partial response (PR) according to RECIST criteria guidelines (version 1.1).

  6. To explore the efficacy of olaparib in terms of overall survival (OS) [ Time Frame: Baseline up to 34 months ]
    The OS defined as the time from the first dose of study drugs until death from any cause or the last date the patient was known to be alive.
