Neratinib, Capecitabine, and Trastuzumab Emtansine in Treating Patients with HER2-Positive Breast Cancer That Has Spread to the Brain

Status: Active

Description

This phase II trial studies how well neratinib, capecitabine, and trastuzumab emtansine work in treating patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer that has spread to the brain. Neratinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Trastuzumab emtansine (T-DM1) is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called DM1. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers DM1 to kill them. Giving neratinib, capecitabine, and trastuzumab emtansine together may be an effective treatment for breast cancer.

  • Prior therapy: * Prior trastuzumab is allowed for all cohorts * Prior capecitabine is NOT allowed for participants enrolled to Cohorts 3A/3B ONLY * Prior lapatinib is allowed for Cohorts 1, 2, and 3B but NOT Cohort 3A * Prior T-DM1 is NOT allowed for Cohorts 4A and 4B, but is required for Cohort 4C; dose reductions on prior T-DM1 for Cohort 4C do not preclude enrollment on Cohort 4C; patients on 4C may have progressed on prior T-DM1 in the CNS or non-CNS sites and had to have tolerated therapy without significant toxicity that would preclude retreatment * No prior therapy with neratinib is allowed on any cohort * There is no limit to the number of previous lines of therapy (including chemotherapy, trastuzumab, and endocrine therapies); at least 2 weeks washout period post chemotherapy, any prior protocol therapy, lapatinib, other targeted or biologic or immunotherapy, or radiation therapy is required prior to study entry * No washout is required for hormonal therapy but concurrent hormonal therapy is not allowed for patients on study; the only exception to this is longstanding ovarian suppression in pre-menopausal patients, if this has been started >= 6 months prior to study enrollment; other hormonal therapies are not allowed while patients are on study
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  • Human immunodeficiency virus (HIV)-positive individuals on combination antiretroviral therapy are eligible for enrollment and will be monitored closely for potential pharmacokinetic interactions with neratinib
  • Concomitant medications should be avoided (when possible) while on study
  • Ability to understand and willingness to sign a written informed consent document
  • For Cohorts 1, 3A/3B, 4B and 4C patients must have new or progressive measurable CNS lesions, as assessed by the patient's treating physician; this includes patients who have progressed after at least one line of standard local treatment for CNS disease (whole brain radiotherapy [WBRT], stereotactic radiosurgery [SRS], or surgical resection as below)
  • In Cohort 2, eligible patients will include those who have CNS disease that is amenable for surgery (typically < 3 brain metastases and with planned resection by neurosurgery); these patients may include those who have received or not received previous treatment(s) for their CNS
  • FURTHER ELIGIBILITY DETAILS FOR PATIENTS WITH PROGRESSIVE DISEASE (COHORTS 1, 3A/3B, 4B, 4C):
  • Patients must have measurable CNS disease, defined as at least one parenchymal brain lesion that can be accurately measured in at least one dimension with longest dimension >= 10 mm by local radiology review; Note: measurable non-CNS disease is NOT required for study participation
  • It is anticipated that some patients may have multiple progressive CNS lesions, one or several of which are treated with SRS or surgery with residual untreated lesions remaining; such patients are eligible for enrollment on this study providing that at least one residual (i.e. non-SRS-treated or non-resected) lesion is measurable (>= 10 mm); the location of the measurable lesion should be documented in the patient chart and case report form
  • Patients who have had prior cranial surgery are eligible, provided that there is evidence of measurable residual or progressive lesions, and at least 2 weeks have passed since surgery; if a patient has surgical resection followed by WBRT, then there must be evidence of progressive CNS disease after the completion of WBRT
  • Except for those in Cohort 4A where prior local CNS therapy is not allowed, patients who have had prior WBRT and/or SRS and then whose prior treated lesions have progressed thereafter are also eligible for all other cohorts; in this case, lesions which have been treated with SRS may be considered as target lesions if there is unequivocal evidence, in the opinion of the treating physician, of progression
  • FURTHER ELIGIBILITY DETAILS FOR PATIENTS WITH OPERABLE DISEASE (COHORT 2):
  • It is anticipated that patients who have intracranial disease amenable to surgery will have measurable CNS disease prior to study entry and to resection; however, this is not an eligibility requirement; measurable disease is also not required to continue on protocol subsequent to surgical resection
  • For patients who undergo surgery, postoperative whole brain radiation therapy will not be allowed while patients are on study; patients will require discontinuation of neratinib if WBRT will be administered; however, if the treating provider feels that targeted radiosurgery (SRS, gamma knife, etc) would be of benefit postoperatively, patients may proceed with this and then begin neratinib AFTER radiation completes
  • Further eligibility details for patients on Cohort 4A: All patients on Cohort 4A will not have received prior radiation or surgery to their brain; prior systemic therapy aimed to treat disease in the brain is allowed (i.e. prior systemic standard therapy or protocol systemic therapy for brain metastases [mets])
  • Note: laboratory tests required for eligibility must be completed within 4 weeks prior to study entry; baseline measurements in the CNS must be documented from tests up to 21 days prior to planned start of protocol therapy unless not covered by insurance; if insurance coverage is an issue, a case by case approval of testing beyond this window may be approved by the overall study principal investigator (PI); other non-laboratory tests must be performed as indicated
  • INCLUSION CRITERIA FOR CONTINUING THERAPY ON THE EXTENSION PHASE:
  • Participants must have met all criteria to be enrolled on the main protocol for receipt of neratinib; at the time of enrollment on the extension phase for Cohorts 1 and 3, patients must have experienced progression of non-CNS disease by RECIST 1.1 criteria

  • Creatinine =< 2 mg/dL or creatinine clearance >= 50 mL/min
  • The effects of trastuzumab, capecitabine, and neratinib on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  • Left ventricular ejection fraction >= 50%, as determined by RVG (MUGA) or echocardiogram within 60 days prior to initiation of extension phase therapy (all cohorts)
  • Ability to understand and the willingness to sign a written informed consent document (all cohorts)

Trial Objectives and Outline

PRIMARY OBJECTIVES:

I. To evaluate the objective response rate (ORR) in the central nervous system (CNS) by composite response criteria in Cohort 1, Cohort 3A, and Cohort 3B.

II. To evaluate the ORR in the CNS by more modern criteria, namely the Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria, separately in Cohorts 4A, 4B, and 4C.

SECONDARY OBJECTIVES:

I. ORR in non-CNS sites (by Response Evaluation Criteria in Solid Tumors [RECIST 1.1] criteria). (All Cohorts)

II. Progression-free survival (PFS) and overall survival (OS). (All Cohorts)

III. CNS response by Macdonald criteria. (Cohort 1 only)

IV. CNS response by volumetric/composite criteria. (Secondary endpoint for Cohorts 4A-4C only as this is primary objective for Cohorts 1, 3A-3B)

V. First site of disease progression. (All Cohorts)

VI. Safety and tolerability of therapy. (All Cohorts)

VII. Time to CNS radiation. (Cohort 4A only)

VIII. Association of circulating tumor cell (CTC) count and OS. (Cohort 1 only)

IX. Assess clinical outcomes for patients who opt to receive trastuzumab and neratinib at the time of non-CNS progression (i.e. toxicity, CNS and non-CNS response, site of first progression, OS). (Cohort 1 only)

EXPLORATORY OBJECTIVES:

I. PFS and OS in patients who undergo craniotomy. (Cohort 2)

II. PFS from the time of addition of capecitabine for Cohort 2 patients.

III. ORR in the CNS for lapatinib-naive patients versus (vs.) lapatinib-treated patients. (All Cohorts)

IV. Explore the association of MET (hepatocyte growth factor receptor) and HER2 co-amplification (in CTCs) with treatment response. (Cohorts 1, 3A/3B)

V. Explore the relationship between the HER2 status of a patient’s primary breast cancer, metastatic lesions, and CTCs using fluorescence in situ hybridization (FISH) for HER2 gene amplification. (Cohorts 1, 3A/3B)

VI. Explore the possible mechanisms of resistance driven by Epidermal Growth Factor Receptor (EGFR) using FISH for EGFR gene amplification in HER2-positive CTCs. (Cohorts 1, 3A/3B)

VII. Assess neratinib concentrations and concentrations of its metabolites in CNS tumor, cerebrospinal fluid (CSF), and plasma at craniotomy in patients who receive neratinib prior to surgery. (Cohort 2)

VIII. Examine neurocognitive function for patients with varying previous therapies for CNS disease. (Cohort 1)

IX. Explore primary archival samples and metastatic samples when able to evaluate for predictors of response and outcome. (Cohorts 3A/3B)

X. Perform molecular characterization of potential resistance mechanisms, predictive biomarkers, and immunological function by collecting blood and tumor specimens. (Cohort 3A/3B, 4A/4B/4C)

XI. Examine changes in the mutational profiles of one’s disease using circulating tumor (ct) deoxyribonucleic acid (DNA) (all Cohort 4 patients) in blood and in CSF (for any Cohort 4 patient undergoing lumbar puncture).

XII. Evaluate patient-reported gastrointestinal (GI) toxicity and its impact on quality of life for patients receiving neratinib and trastuzumab emtansine (T-DM1). (Cohort 4 patients only, cycles 1-3)

XIII. Compare patient-reported and clinician-reported gastrointestinal adverse events during the first 3 cycles of T-DM1 and neratinib therapy. (Cohort 4 patients)

XIV. Evaluate self-reported adherence using the Voils measure to anti-diarrheal prophylaxis during cycle 1 and anti-diarrheal medication diaries during T-DM1 and neratinib therapy. (All Cohort 4 patients)

XV. Compare (exploratory endpoint) symptom reporting for Patient-Reported Outcomes Measurement Information System (PROMIS) and Systemic Therapy Induced Diarrhea Assessment Tool (STIDAT) measures for diarrhea. (Cohorts 4A-4C)

OUTLINE:

COHORT I: Patients receive neratinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

COHORT II: Patients receive neratinib PO QD for 7-21 days and then undergo craniotomy. Patients resume neratinib within 10 days post-operatively.

COHORTS IIIA/IIIB: Patients receive neratinib PO QD on days 1-21 and capecitabine PO twice daily (BID) on days 1-14. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

COHORTS IVA-IVC: Patients receive neratinib PO QD on days 1-21 and trastuzumab emtansine intravenously (IV) over 30-90 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

EXTENSION PHASE: Patients achieving CNS response or disease stability yet develop disease progression outside of the CNS receive trastuzumab intravenously (IV) over 30-90 minutes every 7 or 21 days. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up approximately every 6 months for up to 2 years.
