A Phase III Study of BKM120 With Fulvestrant in Patients With HR+,HER2-, AI Treated, Locally Advanced or Metastatic Breast Cancer Who Progressed on or After mTORi

NCT01633060

Description:

This study was a multicenter, randomized, double-blind, placebo-controlled Phase III study to determine the efficacy and safety of treatment with Buparlisib plus Fulvestrant vs. Placebo plus Fulvestrant in postmenopausal women with hormone Receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative), aromatase inhibitor (AI)-treated, locally advanced or metastatic breast cancer whose disease progressed on or after mammalian target of rapamycin inhibitor (mTORi)-based treatment. Patients were randomized in 2:1 ratio to treatment with buparlisib 100 mg daily in combination with fulvestrant 500 mg or placebo daily in combination with fulvestrant 500 mg. Randomization was stratified according to visceral disease status (present or absent).

Eligibility Criteria

        Inclusion Criteria:

          -  Postmenopausal women

          -  Breast cancer that is locally advanced or metastatic

          -  HER2 negative disease, and a known positive hormone receptor status (common breast
             cancer classification tests)

          -  A tumor sample must be shipped to a central lab for identification of biomarkers (PI3K
             activation status) before randomization

          -  Prior treatment with AIs

          -  Evidence of progression to the combination of mTORi and endocrine therapy given as the
             last therapy prior to study entry

          -  Concurrent malignancy or malignancy within 3 years prior to start of study treatment

          -  Certain drugs or radiation within 2-4 weeks of enrollment

          -  Increasing or chronic treatment (> 5 days) with corticosteroids or another
             immunosuppressive agent

          -  Active heart (cardiac) disease or a history of cardiac dysfunction as defined in the
             protocol

Maximum Eligible Age:N/A
Minimum Eligible Age:18 Years
Eligible Gender:Female
Healthy Volunteers:No

Primary Outcome Measures

Measure:Progression Free Survival (PFS)
Time Frame:Up to approx. 5.5 months
Safety Issue:
Description:PFS is defined as time from date of randomization to the date of the event, defined as the first radiologically documented disease progression or death due to any cause. PFS is based on local investigator assessment. Patients will be followed up for the duration of the study and for an expected average of every 6 weeks after randomization.

Secondary Outcome Measures

Measure:Overall survival (OS)
Time Frame:Up to approx. 21 months
Safety Issue:
Description:Time from date of randomization to the date of death from any cause. Patients will be followed up for the duration of the study and for an expected average of every 3 months after end of treatment.
Measure:Overall response rate (ORR)
Time Frame:Up to approx. 5.5 months
Safety Issue:
Description:Proportion of patients, in the full population and by PIK3CA mutational status based on ctDNA, with best overall response of complete response (CR) or partial response (PR). ORR will be assessed according to RECIST 1.1 criteria. Patients will be followed up for the duration of the study and for an expected average of every 6 weeks after randomization.
Measure:Clinical benefit rate (CBR)
Time Frame:Up to approx. 5.5 months
Safety Issue:
Description:Proportion of patients, in the full population and by PIK3CA mutational status based on ctDNA, with best overall response of complete response (CR) or partial response (PR) or stable disease (SD) or non-CR/non-PD lasting more than 14 weeks. CBR will be assessed according to RECIST 1.1 criteria. Patients will be followed up for the duration of the study and for an expected average of every 6 weeks after randomization.
Measure:Type, frequency and severity of adverse events
Time Frame:at minimum at each study visit and up to approx. 8 months
Safety Issue:
Description:Safety will be determined by type, frequency and severity of adverse events per CTCAEv4.03 and Type, frequency and severity of laboratory toxicities per CTCAEv4.03. Patients will be followed up for the duration of the study.
Measure:Plasma concentration-time profiles of BKM120 - pharmacokinetics (PK)
Time Frame:C1D1, C1D15, C2D1,C3D1 and C4D1 (a cycle [C] = 4 weeks), D = Day
Safety Issue:
Description:Plasma concentration-time profiles of BKM120 and appropriate individual PK parameters.
Measure:Patient reported outcome for global health status/QoL
Time Frame:C1D1, C2D15, C4D1, then every 8 weeks until discontinuation (a cycle [C] = 4 weeks).
Safety Issue:
Description:Time to definitive deterioration in the global health status/QoL scale score. Change from baseline in the global health status/QOL scale score. Patients will be assessed up to approx. 5.5 months.
Measure:Progression Free Survival (PFS) in PIK3CA mutational status
Time Frame:Up to approx. 5.5 months
Safety Issue:
Description:PFS by PIK3CA mutational status based on ctDNA assessment is defined as time from date of randomization to the date of the event, defined as the first radiologically documented disease progression or death due to any cause. Patient will be followed up to the duration of the study and for an expected avrage of every 6wks after randomization
Measure:Overall survival (OS) in PIK3CA mutational status
Time Frame:Up to approx. 21 months
Safety Issue:
Description:OS by PIK3CA mutational status based on ctDNA is defined as the time from date of randomization to the date of death from any cause. Patients will be followed up for the duration of the study and for an expected average of every 3 months after end of treatment.
