Study Details

Study Description

Brief Summary

This ComboMATCH phase II trial compares the usual treatment alone (fulvestrant) to using binimetinib plus the usual treatment in patients with hormone receptor positive breast cancer that has spread to other places in the body (metastatic) and has an NF1 genetic change. Fulvestrant is a hormonal therapy that binds to estrogen receptors in tumor cells, resulting in estrogen receptor destruction and decreased estrogen binding, which may inhibit the growth of estrogen-sensitive tumor cells. Binimetinib is a targeted therapy that may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The addition of binimetinib to fulvestrant in breast cancers with an NF1 genetic change could increase the percentage of tumors that shrink as well as lengthen the time that the tumors remain stable (without progression) as compared to fulvestrant alone.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

PRIMARY OBJECTIVES:
  1. To determine whether the combination of fulvestrant and binimetinib improves progression-free survival (PFS) compared to treatment with fulvestrant alone in patients not previously treated with fulvestrant. (Cohort 1) II. To determine whether overall response rate (ORR) within 4 months in patients who have previously progressed on a fulvestrant-containing regimen is greater than 10%, as a historical comparison, when these patients receive combination fulvestrant and binimetinib therapy. (Cohort 2)
SECONDARY OBJECTIVES:
  1. To estimate ORR at any time after the start of the treatment for Cohort 2 and separately for the two arms in Cohort 1.

  2. To estimate PFS distribution in Cohort 2. III. To estimate clinical benefit rate separately for the two arms in Cohort 1 and Cohort 2.

  3. To determine the safety and toxicity profile in both cohorts. V. To estimate the overall survival (OS) in both cohorts. VI. To assess concordance between the tumor mutational profile generated by the designated laboratories and whole exome sequencing (WES) performed by the Molecular Diagnostic Network (MDNet). The ribonucleic acid (RNA) sequencing (RNAseq) assay of the tumor tissue sample is performed by MDNet to assess additional transcriptomic anomaly. The pre-treatment biopsy mutation profile and the pre-treatment circulating tumor deoxyribonucleic acid (DNA) (ctDNA) mutation profile from plasma is described in detail in the ComboMATCH Registration protocol.

EXPLORATORY BIOMARKER OBJECTIVES:
  1. To analyze the cell-free (cf)DNA at progression to determine the changes in cfDNA profile in order to understand blood-based mutation dynamics.

  2. To analyze RNAseq at progression to determine potential pathways that are altered that may contribute to the sensitivity/resistance.

  3. To discover/detect novel biomarkers using microscaled proteogenomics by analyzing the proteins and phosphor-proteins along with genomics to determine potential pathways that may correlate with the response to the combination treatment.

  4. To detect the loss of NF1, using immunohistochemistry staining to precisely measure the level of the NF1 protein.

  5. To determine the variant allele frequency (VAF) of mutant NF1 measuring by using droplet digital polymerase chain reaction (ddPCR) for the targeted NF1 gene level.

OUTLINE: Patients who are fulvestrant naive are assigned to Cohort I, while patients who are fulvestrant resistant are assigned to Cohort II.

COHORT I: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive fulvestrant intramuscularly (IM) and binimetinib orally (PO) throughout the trial. Patients also undergo a computed tomography (CT), magnetic resonance imaging (MRI), or bone scan and tumor biopsy during screening and on study.

ARM II: Patients receive fulvestrant IM throughout the trial. Patients who progress on fulvestrant alone are asked to reaffirm their willingness to enroll in cohort II. Patients not willing to transition to cohort II continue further therapy as clinically indicated. Patients undergo a CT, MRI, or bone scan and tumor biopsy during screening and on study.

COHORT II: Patients receive fulvestrant IM and binimetinib PO throughout the trial. If the patient progressed on fulvestrant, the loading dose of fulvestrant is omitted. Patients undergo a CT, MRI, or bone scan and tumor biopsy during screening and on study.

  • Outcome Measures

    Primary Outcome Measures

    1. Progression free survival (PFS) (Cohort I) [The duration between randomization and progression or death from all cause, whichever happens first, assessed up to 5 years]

      PFS of the two study arms will be compared by log-rank test (1-sided, alpha=0.1). Kaplan-Meier plot will be provided. Hazard ratio (HR) and the corresponding 95% confidence interval (CI) will be estimated by Cox proportional model using treatment as covariate.

    2. Objective response rate (ORR) (Cohort II) [Within 4 months of the start of treatment]

      ORR is the percentage of patients who reaches a complete or partial response (defined by Response Evaluation Criteria in Solid Tumors [RECIST] version[v]1.1) within 4 months of the start of the treatment. ORR will be calculated as the proportion of patients achieved partial response (PR) or complete response (CR) within 4 months after the initiation of the treatment. ORR will be reported with corresponding 95% exact CI. Patients who have withdrawn from the study before any efficacy follow up are considered non-evaluable for clinical response and will be replaced.

    Secondary Outcome Measures

    1. ORR for each study arm (Cohort I) [Any time after the start of the treatment, assessed up to 5 years]

      ORR is the percentage of patients who reach a complete or partial response (defined by RECIST v1.1) any time after the start of the treatment. ORR for each study arm will be calculated with corresponding 95% exact CI. Fisher exact test will be used to compare the ORR of the two study arms.

    2. ORR (Cohort II) [Any time after the start of the treatment, assessed up to 5 years]

      ORR is the percentage of patients who reach a complete or partial response (defined by RECIST v1.1) any time after the start of the treatment.

    3. Clinical benefit rate [Any time after the start of the treatment, assessed up to 5 years]

      Defined as proportion of patients who achieved a CR, PR, or stable disease defined by RECIST criteria any time after the start of the treatment. Clinical benefit rate will be analyzed for each arm of cohort I and cohort II as described for ORR. ORR for each study arm will be calculated with corresponding 95% exact CI. Fisher exact test will be used to compare the ORR of the two study arms.

    4. PFS (Cohort II) [The duration between randomization and progression or death from all cause, whichever happens first, assessed up to 5 years]

      PFS for cohort II will be summarized using the Kaplan-Meier's method. Median PFS with corresponding 95% CI will be provided.

    5. Overall survival (OS) [The duration between randomization and death of all causes, assessed up to 5 years]

      OS for cohort I will be analyzed as described for PFS in cohort I and OS for cohort II will be analyzed as described for PFS in cohort II. PFS of the two study arms will be compared by log-rank test (1-sided, alpha=0.1). Kaplan-Meir plot will be provided. HR and the corresponding 95% CI will be estimated by Cox proportional model using treatment as covariate. PFS for Cohort 2 will be summarized using the Kaplan-Meir's method. Median PFS with corresponding 95% CI will be provided.

    6. Incidence of adverse events [Up to 5 years]

      The grade of toxicity measurement will follow Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The distribution by treatment group of the highest grade of each CTCAEs experienced by each patient categorized will be tabulated. The tabulations will also be reviewed on a semi-annual basis by the Data Monitoring Committee. These tabulations will include summaries by system organ class and summaries by term under each system organ class.

    Other Outcome Measures

    1. Analysis of integrated and exploratory biomarkers [Up to 5 years]

      A separate statistical analysis plan will be developed for the integrated and exploratory biomarker analysis. Concordance of diagnostic tumor mutation profile generated by the designated laboratory, the pre-treatment biopsy mutation profile, and the pre-treatment circulating tumor deoxyribonucleic acid mutation profile will be assessed. Details are provided in the statistical plan of the ComboMATCH Registration protocol.
