NCT02088684

  Purpose

The purpose of this trial is to explore the clinical utility of the three investigational agents in HR+, HER2- breast cancer. LEE011 (CDK4/6 inhibitor), BKM120 (PI3K-pan class I-inhibitor) and BYL719 (PI3K-alpha specific class I inhibitor) in combination with fulvestrant.

This is a multi-center, open-label Phase Ib/II study. The Phase Ib portion of the study is a dose escalation to estimate the MTD and/or RP2D for three regimens: LEE011 with fulvestrant; LEE011 and BKM120 with fulvestrant; LEE011and BYL719 with fulvestrant.

The Phase II portion of the study will be a randomized study to assess the anti-tumor activity as well as safety and tolerability of LEE011 with fulvestrant to LEE011 and BKM120 with fulvestrant, and LEE011 and BYL719 with fulvestrant in patients with ER+/HER2- locally advanced or metastatic breast cancer.

Approximately 216 adult women with ER+/HER2- locally advanced or metastatic breast cancer will be enrolled.

Primary Outcome Measures:
  • Incidence of Dose limiting toxicities (DLTs) - Phase lb only [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
    Dose limiting toxicities

  • Progression free survival (PFS) - Phase ll only [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    Progression Free Survival per RECIST v 1.1 by local investigator assessment


Secondary Outcome Measures:
  • Safety and Tolerability of the combinations of LEE011 with fulvestrant, LEE011 + BKM120 with fulvestrant and LEE011 + BYL719 with fulvestrant [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]
    Adverse Events (AEs), serious AEs (SAEs), changes in hematology and chemistry values, vital signs, electrocardiograms (ECGs), dose interruptions, reductions and dose intensity

  • Plasma concentration-time profiles of LEE011, BKM120, BYL719 and fulvestrant. [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    To characterize the PK profiles of LEE011, BKM120, BYL719, and fulvestrant when used in combination as well as to evaluate any other clinically significant metabolites that may be identified. PK parameters for LEE011, BKM120 and BYL719, including but not limited to Cmax, Cmin, Tmax, AUCtau, accumulation ratio (Racc),and Ctrough values for fulvestrant.

  • Overall Response Rate (ORR) [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    ORR is defined as the proportion of patients with a best overall response of complete response or partial response.

  • Duration of Response (DOR) [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    Duration of Response is calculated as the time from the date of first documented response (complete response (CR) or partial response (PR)) to the first documented date of progression or death due to underlying cancer.

  • Progression Free Survival (PFS) (phase l only) [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    PFS is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to any cause.

  • Overall Survival (OS) - Phase II only [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    OS is defined as the time from date of randomization/start of treatment to date of death due to any cause. If a patient is not known to have died, survival will be censored at the date of last known date patient alive.
