Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Histologically or cytologically confirmed invasive breast cancer, which at time of study entry is either stage III (locally advanced) disease not amenable to curative therapy or stage IV disease. Histological confirmation of recurrent/metastatic disease is encouraged but not required if clinical evidence of stage IV disease recurrence is available.
  • ER and/or Progesterone Receptor (PgR )positive breast cancer (10% or more of infiltrating cancer cells exhibit nuclear staining for ER and/or PgR)
  • Have had progressive disease or development of new metastatic disease while on treatment or within 12 months of treatment with an aromatase inhibitor and/or Fulvestrant in adjuvant or metastatic setting
  • Have measurable (defined as at least 1 lesion that can be accurately measured in at least 1 dimension [longest diameter to be recorded], with minimum lesion size ≥ 2cm on conventional measurement techniques or ≥ 1cm on spiral computed tomography [CT] scan), or evaluable disease. Patients with lytic or blastic bone disease as only site of disease will be eligible for the study. These patients will be evaluable for progression but not for response.
  • Primary tumor was HER-2 negative (IHC 0 or IHC 1+/2+ and Fluorescence in situ hybridization [FISH] ≤ 1.9)
  • Patients could have received prior Tamoxifen either as adjuvant therapy or for stage IV disease

  • IV bisphosphonate and denosumab for bony metastatic disease will be allowed
  • Palliative radiation therapy to bony metastases will be allowed
  • Adequate bone marrow function per good medical practice. Results of these tests do not determine eligibility. Minor deviations are acceptable if they do not impact safety in the judgment of the treating physician. Absolute neutrophil count (ANC) ≥ 1500/mm3, platelet count ≥ 100,000/mm3, and hemoglobin ≥ 10 g/dL
  • Adequate kidney function: serum creatinine of ≤ 1.5mg/dl and/or creatinine clearance of ≥ 60 mL/min

  • Must have a serum albumin ≥ 3.0 g/dL.
  • Must be informed of investigational nature of study and must sign informed consent in accordance with institutional rules.
  • Pretreatment lab values must be performed within 14 days of patient registration and other baseline studies within 30 days.
  • Patients will have a baseline bone scan, Computerized Tomography (CT) chest, abdomen and pelvis or Positron Emission Tomography (PET)/CT.
  • If previously treated brain metastasis and free of central nervous system (CNS) symptoms and > 3 months from treatment of brain metastasis are eligible

Who cannot join

  • Prior HER-2 targeted therapy for metastatic disease
  • Has uncontrolled brain metastasis or leptomeningeal disease
  • Has rapidly progressing and/or bulky disease which in the opinion of the investigator may be more appropriately treated with a chemotherapy-based strategy.
  • Has an uncontrolled intercurrent illness including, but not limited to ongoing or active infection requiring parenteral antibiotics or psychiatric illness/social situations that would limit compliance with study requirements.
  • Concomitant requirement for medication classified as CYP3A4 inducers or inhibitors
  • Patients with GI tract disease resulting in an inability to take oral medication, malabsorption syndrome, a requirement for IV alimentation, prior surgical procedures affecting absorption, uncontrolled inflammatory GI disease (eg, Crohn's, ulcerative colitis).
Show all 22Show fewer
  • Current active hepatic or biliary disease (exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases or stable chronic liver disease per investigator assessment)
  • Renal function as measured by creatinine clearance <3 0ml/min (ratio to norm < 0.1)
  • HIV-positive patients receiving combination antiretroviral therapy
  • Pregnant women
  • Active cardiac disease defined as:
  • History of uncontrolled or symptomatic angina
  • History of arrhythmias requiring medications, or clinically significant, with the exception of asymptomatic atrial fibrillation requiring anticoagulation
  • Myocardial infarction < 6 months from study entry
  • Uncontrolled or symptomatic congestive heart failure
  • Ejection fraction below institutional normal limit
  • Any other cardiac condition, which in the opinion of treating physician, would make this protocol unreasonably hazardous for the patient
  • History of another primary cancer, with exception of:
  • curatively resected nonmelanomatous skin cancer
  • curatively treated cervical carcinoma in-situ
  • other primary solid tumor curatively resected treated with no known active disease present and no treatment administered for the last 3 years.
  • Life expectancy of < 2 months

About this study

Official title: Phase II Trial of Lapatinib in Women With Hormone Receptor Positive (Estrogen Receptor [ER] and/or Progesterone Receptor [PR] +) Human Epidermal Growth Factor Receptor 2 (HER-2) Negative Metastatic Breast Cancer Who Have Failed Prior Antihormone Therapy

Hormone receptor positive breast cancer is the most common type of breast cancer, comprising 70-80% of all breast cancers. Endocrine therapy is the main type of initial treatment for patients with your type of breast cancer. Endocrine therapy is treatment that tries to remove, or block certain hormones from binding to the cancer cells and thus slow or stop the growth of cancer. Although most patients with your type of breast cancer respond initially to endocrine therapies, it can lose its effectiveness. New therapies for this type of cancer are needed.

Read the detailed description

Endocrine therapy forms the backbone of treatment for both early stage and advanced stage hormone receptor positive breast cancer. Although most patients with advanced estrogen receptor positive metastatic disease respond initially to endocrine therapies, this response is short lived. New therapies able to provide additional benefit to patients with hormone receptor positive, endocrine-resistant, advanced metastatic breast cancer are required. This study proposes to add lapatinib to endocrine therapy to treat hormone receptor positive HER-2 negative metastatic breast cancer patients.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing lapatinib in people with Metastatic Breast Cancer, run by University of Kansas Medical Center at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 1 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression Free Survival (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jul 2019.
