Brief Summary:
Triple negative breast cancer (TNBC) is a difficult to treat molecular subtype with a poor survival. TNBC can be divided into at least two molecular entities; BRCA-like and non-BRCA-like. In this trial we would like to investigate whether a molecular subgroup exists within TNBCs that derives a benefit from atezolizumab added to first line chemotherapy.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Carbo/cyclo Drug: Carbo/cyclo + atezolizumab Drug: Paclitaxel Drug: Paclitaxel + Atezolizumab Phase 2

Detailed Description:
Atezolizumab, a humanized monoclonal antibody that targets human programmed death-ligand 1 (PD-L1) has shown activity in TNBC. Early clinical trials with anti-PD-(L)1 monotherapy have shown that the median duration to response in TNBC is remarkably long (18 weeks) compared to cytotoxic chemotherapy. Since advanced TNBC is characterized by rapid disease progression, most patients with TNBC may not have the opportunity to derive benefit from immunotherapy. We hypothesize that by combining atezolizumab with paclitaxel or carboplatin-cyclophosphamide the desired rapid tumor control will be obtained with chemotherapy and subsequently atezolizumab can result in durable responses in a significant subset of patients. It is unknown whether addition of atezolizumab to first line chemotherapy in TNBC is more beneficial than adding this antibody to a second line treatment schedule. Because of this and because of the poor outcome of patients with advanced TNBC experiencing disease progression after first line palliative chemotherapy, patients who were randomized to a chemotherapy only arm in this study will be offered the opportunity to cross over to the other chemotherapy regimen plus atezolizumab at disease progression.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Validate the BRCA-like test [ Time Frame: assessed up to 120 months ]
    Validate the BRCA-like test in predicting differential PFS with first line alkylating and platinum agents when compared to paclitaxel in TNBC


Secondary Outcome Measures :
  1. Improvement of objective response by adding atezolizumab [ Time Frame: assessed up to 120 months ]
    Determine whether atezolizumab added to first line palliative chemotherapy improves objective response in TNBC

  2. Define predictive biomarkers for objective response gain [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 120 months ]
    Define predictive biomarkers for objective response gain of the addition of atezolizumab to first line chemotherapy; e.g PD-L1, intratumoral CD8, TILs and pre-treatment LDH

  3. Define predictive biomarkers for PFS gain [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 120 months ]
    Define predictive biomarkers for PFS gain of carboplatin-cyclophosphamide or paclitaxel chemotherapy

  4. Determine PFS in BRCA like TNBC [ Time Frame: From date of randomization until date of first documented progression or date of death, which ever comes first, assessed up to 120 months ]
    Determine whether an alkylating platinum regimen is more effective then paclitaxel regarding PFS in BRCA like TNBC

  5. Determine PFS in non BRCA like TNBC [ Time Frame: From date of randomization until date of first documented progression or date of death, which ever comes first, assessed up to 120 months ]
    Determine whether paclitaxel is more effective then an alkylating platinum regimen regarding PFS in non BRCA like TNBC

  6. Overall survival (OS) [ Time Frame: assessed up to 120 months ]
    Evaluation of overall survival (OS) for all (sub)group comparisons as pre-specified for PFS

  7. Toxicity of all study regimens [ Time Frame: Assessed at 1 year ]
    Adverse events will be graded according to NCI Common Toxicity Criteria version 4.03

  8. Determine PFS in cross over [ Time Frame: At 6 and 12 months and up to 120 months ]
    Determine the PFS and objective response after cross over to the other chemotherapy regimen with atezolizumab

  9. Determine PFS in TNBC molecular subtypes [ Time Frame: Assessed up to 120 months ]
    Determine whether TNBC molecular subtypes as defined by gene expression are predictive for differential PFS benefit of atezolizumab added to first line chemotherapy
