A Phase II Combination of Trastuzumab and Ixabepilone Versus Trastuzumab and Docetaxel in Patients With Advanced and/or Metastatic Breast Cancer

9 de febrero de 2016 actualizado por: R-Pharm

Randomized Phase II Study of Ixabepilone Plus Trastuzumab vs. Docetaxel Plus Trastuzumab in Female Subjects With Her2+ Locally Advanced and/or Metastatic Breast Cancer

The purpose of this randomized, Phase 2 open-label study was to assess the response rate of participants with Human Epidermal Growth Factor Receptor 2 (Her2+) locally advanced and/or metastatic breast cancer (not previously treated with chemotherapy or trastuzumab) to treatment with ixabepilone plus trastuzumab and/or docetaxel plus trastuzumab.

Intervención / Tratamiento
Experimental: Arm A
trastuzumab 4 mg/kg loading dose, then 2 mg/kg weekly + ixabepilone 40 mg/m^2 intravenous (IV) over 3 hours once every 21 days (using a 21-day cycle); until disease progression or unacceptable toxicity.
Droga: ixabepilone

Ixabepilone 40 mg/m^2 was administered as a 3-hour I.V. continuous infusion on Day 1 in a 21-day cycle until disease progression or unacceptable toxicity.

For the first cycle, ixabepilone was administered the day following the first dose of trastuzumab (in the first cycle trastuzumab was given on Day 0); in all the following cycles, ixabepilone was administered immediately after the subsequent doses of trastuzumab if the preceding dose of trastuzumab was well tolerated.

  • BMS-247550
  • Epotilona
  • IXEMPRA®
Droga: trastuzumab
Trastuzumab was administered as an IV infusion on Days 1, 8, and 15 of each 21-day cycle at a dose of 2 mg/kg until disease progression or unacceptable toxicity. In cycle 1, a loading dose of 4 mg/kg was administered as a 90-minute IV infusion on a day before initial administration of chemotherapy (i.e. on Day 0). Trastuzumab was given immediately prior to ixabepilone (Arm A) or docetaxel (Arm B) in all subsequent cycles as a 30-minute IV infusion if the initial dose was well tolerated.
Comparador activo: Arm B
trastuzumab 4 mg/kg loading dose, then 2 mg/kg weekly + docetaxel 100 mg/m^2 IV over 1 hour once every 21 days (using a 21-day cycle); until disease progression or unacceptable toxicity.
Droga: trastuzumab
Trastuzumab was administered as an IV infusion on Days 1, 8, and 15 of each 21-day cycle at a dose of 2 mg/kg until disease progression or unacceptable toxicity. In cycle 1, a loading dose of 4 mg/kg was administered as a 90-minute IV infusion on a day before initial administration of chemotherapy (i.e. on Day 0). Trastuzumab was given immediately prior to ixabepilone (Arm A) or docetaxel (Arm B) in all subsequent cycles as a 30-minute IV infusion if the initial dose was well tolerated.
Droga: docetaxel
Docetaxel 100 mg/m^2 was administered as a 1-hour IV continuous infusion on Day 1 in a 21-day cycle until disease progression or unacceptable toxicity. For the first cycle, docetaxel was administered the day following the first dose of trastuzumab (i.e. in the first cycle trastuzumab was given on Day 0); in all following cycles, docetaxel was administered immediately after trastuzumab if the preceding dose of trastuzumab was well tolerated.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Objective Response (OR; Assessed by Response Evaluation Criteria in Solid Tumors [RECIST] Version 1.1)
Periodo de tiempo: Assessed every 6 weeks from initiation of study therapy up to 12 months; then every 3 months until disease progression (maximum time that any participant was on therapy was 108 weeks)
Percentage of participants with best overall response (BOR) of either complete response (CR) or partial response (PR) according to RECIST version 1.1 as determined by the investigator. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (LD) of all lesions. CR and PR criteria should be met again after 4 weeks and before 6 weeks after initial assessment. A two-sided confidence interval (CI) was computed using the Clopper-Pearson method.
Assessed every 6 weeks from initiation of study therapy up to 12 months; then every 3 months until disease progression (maximum time that any participant was on therapy was 108 weeks)
Number of Participants With Best Overall Response (BOR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1
Periodo de tiempo: Assessed every 6 weeks from initiation of study therapy up to 12 months; then every 3 months until disease progression (maximum time that any participant was on therapy was 108 weeks).
BOR was the best response recorded from the start of treatment until disease progression or recurrence (taking the smallest measurement recorded since the start of treatment as reference). CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the LD of all lesions. CR and PR criteria should be met again after 4 weeks and before 6 weeks after initial assessment. Stable disease (SD)=Neither sufficient increase to qualify for PD nor sufficient shrinkage to qualify for PR. Refer to Outcome Measure 3 for definition of PD.
Assessed every 6 weeks from initiation of study therapy up to 12 months; then every 3 months until disease progression (maximum time that any participant was on therapy was 108 weeks).
