Eribulin in HER2 Negative Metastatic BrCa

NCT01827787

Description:

Improvements in outcomes with metastatic breast cancer (MBC) have been observed in the last 30 years, however, overall prognosis remains poor with median survival of 2 to 3 years. Long term complete responses are observed only for a minority of MBC patients (2-5%) and MBC remains an incurable disease for most patients. Eribulin is a chemotherapy approved by the US FDA in November of 2010 to treat patients with MBC who have received at least two prior chemotherapy regimens. In this research study, the investigators are looking to see how well eribulin helps participants with MBC in an earlier-line setting. Eribulin works by interfering with cancer cell division, growth and spread.

Purpose

Improvements in outcomes with metastatic breast cancer (MBC) have been observed in the last 30 years, however, overall prognosis remains poor with median survival of 2 to 3 years. Long term complete responses are observed only for a minority of MBC patients (2-5%) and MBC remains an incurable disease for most patients. Eribulin is a chemotherapy approved by the US FDA in November of 2010 to treat patients with MBC who have received at least two prior chemotherapy regimens. In this research study, the investigators are looking to see how well eribulin helps participants with MBC in an earlier-line setting. Eribulin works by interfering with cancer cell division, growth and spread.

Detailed Description

      Based on positive results in heavily pre-treated MBC patients, eribulin is being studied as
      first-line or second-line chemotherapy treatment. This is a non-randomized, open label study
      with participants enrolled in one of two cohorts: Cohort 1. Hormone receptor
      (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative (HR+/HER2-) or Cohort
      2: Triple negative breast cancer (TNBC) meaning HR-negative/HER2-negative (HR-/HER2-). HR-
      means progesterone receptor-negative (PR-) and estrogen receptor-negative (ER-). Beyond
      efficacy as measured primarily by response to treatment, investigators will evaluate safety,
      tolerability and quality of life. In particular, it is hypothesized that eribulin may have
      lower rates of neuropathy, a common side effect of many of the major chemotherapeutics with
      activity in MBC. The investigators will study the effect eribulin has on the nerves through
      regular questionnaires that ask about any nerve-related symptoms. The investigators also plan
      to send blood samples to explore if gene markers may indicate increased sensitivity to the
      nerve effects of eribulin.

Primary Outcome Measures

Measure:Overall Response Rate (ORR)
Time Frame:Disease was evaluated radiologically at baseline and every 9 weeks on treatment; Maximum treatment duration was 38 cycles/26 months (Cohort 1) and 17 cycles/12 months (Cohort 2)
Safety Issue:
Description:ORR was defined as the percentage of participants achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.

Secondary Outcome Measures

Measure:Progression-Free Survival (PFS)
Time Frame:Disease was evaluated radiologically at baseline and every 9 weeks on and off treatment; Median (maximum) PFS follow-up was 12.6 (27.1) months in Cohort 1 and 12.4 (14.3) months in Cohort 2.
Safety Issue:
Description:PFS based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) requiring removal from the study or death. Participants alive without PD are censored at date of last disease assessment. Per RECIST 1.1 for target lesions: PD is at least a 20% increase in sum longest diameter (LD), taking as reference the smallest sum on study with at least 5 mm absolute increase or the appearance of one or more new lesions. For non-target lesions, PD is appearance of one or more new lesions or unequivocal progression of existing non-target lesions.
Measure:Time to First Response (TTR)
Time Frame:Disease was evaluated radiologically at baseline and every 9 weeks on treatment; Maximum treatment duration was 38 cycles/26 months (Cohort 1) and 17 cycles/12 months (Cohort 2).
Safety Issue:
Description:TTR is defined as the time from first dose of study treatment until the earliest date that complete response (CR) or partial response (PR) based on RECIST 1.1 criteria is objectively documented. Non-CR, non-PR participants are censored at date of last disease assessment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response requires 4 week or later confirmation and assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.
Measure:Duration of Overall Response (DOR)
Time Frame:Disease was evaluated radiologically at baseline and every 9 weeks on and off treatment; Median (maximum) DOR follow-up was 12.6 (27.1) months in Cohort 1 and 12.4 (14.3) months in Cohort 2.
Safety Issue:
Description:DOR is defined as the that response criteria for CR or PR (whichever is recorded first) are first met until the date that PD or death from any cause is first objectively documented. Participants who do not have PD will be censored on date of last disease assessment.
Measure:Percentage of Participants With Grade 1-3 Treatment-Related Peripheral Sensory Neuropathy
Time Frame:Adverse events were assessed every cycle throughout treatment. Maximum treatment duration was 38 cycles/26 months (Cohort 1) and 17 cycles/12 months (Cohort 2)
Safety Issue:
Description:The percentage of treated participants experiencing grade 1-3 peripheral sensory neuropathy with treatment attribution of possible, probable or definite based on Common Toxicity Criteria for Adverse Events version 4 (CTCAEv4) as reported on case report forms.
Measure:Percentage of Participants With Grade 1-3 Treatment-Related Peripheral Motor Neuropathy
Time Frame:Adverse events were assessed every cycle throughout treatment. Maximum treatment duration was 38 cycles/26 months (Cohort 1) and 17 cycles/12 months (Cohort 2)
Safety Issue:
Description:TThe percentage of treated participants experiencing grade 1-3 peripheral motor neuropathy with treatment attribution of possible, probable or definite based on Common Toxicity Criteria for Adverse Events version 4 (CTCAEv4) as reported on case report forms.
Measure:Functional Assessment of Cancer Therapy-Breast Cancer Subscale (FACT-BCS) Change Score From Baseline
Time Frame:Assessed at baseline and on treatment day 1 of cycles 2, 3, 5, 7, 9 and 11
Safety Issue:
Description:The FACT-BCS is a validated, self-administered questionnaire which captures quality of life (QOL) concerns specific to breast cancer patients. (Brady MJ, et al. Reliability and validity of the Functional Assessment of Cancer Therapy-Breast quality-of-life instrument. JCO 1997; 15:974-86). The FACT-BCS has 9-items scored on a 5-point Likert scale (Not at all, A little bit, Somewhat, Quite a bit, Very much) with a maximum score of 36. A higher score indicates better QOL. A minimal clinically important difference is 3-5 points.
Measure:Functional Assessment of Cancer Therapy-Neurotoxicity Subscale (FACT-Ntx) Change Score From Baseline
Time Frame:Assessed at baseline and on treatment day 1 of cycles 2, 3, 5, 7, 9 and 11
Safety Issue:
Description:The FACT-Ntx is a validated, self-administered questionnaire which captures quality of life (QOL) concerns specific to patients suffering from neurotoxicity. (Calhoun EA, et al. Psychometric evaluation of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (Fact/GOG-Ntx) questionnaire for patients receiving systemic chemotherapy. Int J Gynecol Cancer 2003; 13:741-8). The FACT-Ntx has 11-items scored on a 5-point Likert scale (Not at all, A little bit, Somewhat, Quite a bit, Very much) with a maximum score of 44. A higher score indicates better QOL. A minimal clinically important difference is 3-5 points.
