Study Of Lapatinib In Patients With Relapsed Or Refractory Inflammatory Breast Cancer

24. September 2015 aktualisiert von: GlaxoSmithKline

A Phase II Study to Evaluate the Efficacy, Safety and Pharmacodynamics of Lapatinib in Patients With Relapsed or Refractory Inflammatory Breast Cancer

This study was designed to determine how effective and safe a new investigational drug, lapatinib, is in treating patients with treatment refractory or relapsed inflammatory breast cancer. Tumor tissue collected pre-treatment and at Day 28 will be examined for biologic activity by IHC (immunohistochemistry). Treatment will consist of daily oral therapy with lapatinib. A patient may continue treatment as long as they are receiving benefit. Blood samples for hematology and chemistry panels, MUGA/ECHO (multigated acquisition/echocardiogram) exams and physical exams will be performed throughout the study to monitor safety.

Detaillierte Beschreibung

This Phase II open label, multicenter study is designed to evaluate the efficacy, safety, and pharmacodynamic effects of oral lapatinib administered as a single agent therapy to patients with relapsed or refractory inflammatory breast cancer. Eligible patients must have a diagnosis of inflammatory breast cancer based on clinicopathologic criteria, tumor that is readily accessible for biopsy, and must have previously received treatment with an anthracycline and taxane-containing regimen (30 patients) plus trastuzumab (90 patients). Patients enrolled must have tumors that overexpress ErbB2, with or without co-expression of ErbB1. The primary objective for this study is to evaluate the objective response rate (defined as complete response plus partial response). Secondary objectives are to evaluate clinical benefit including quality of life parameters, progression-free survival, overall survival, time-to-response, response duration, safety and tolerability, pharmacodynamic effects on intracellular mediators that regulate tumor cell growth and survival, as well as effects on proteomic profile, and circulating levels of extracellular domains of ErbB1 and ErbB2 in peripheral blood.

Inclusion criteria:

  • Must have a life expectancy of at least 12 weeks.
  • Has a left ventricular ejection fraction (LVEF) ≥ 50%, or ≥ lower limit of normal for the institution, based on ECHO or MUGA.
  • Aspartate and alanine transaminase (AST or ALT) ≤ 3 times the upper limit of the reference range (patients with liver metastases may have AST and ALT ≤ 5 times the upper limit of the reference range and may be enrolled).
  • Total bilirubin ≤ 3.0 mg/dL.
  • Serum creatinine ≤ 2.0 mg/dL or calculated creatinine clearance (CrCl) ≥ 30 mL/min
  • Adequate bone marrow function. Hemoglobin ≥ 9 gm/dL. Absolute granulocyte count ≥ 1,500/mm³ (1.5 x 10^9/L). Platelets ≥ 75,000/mm³ (100 x 10^9/L).

  • At least 18 years of age.
  • Has either measurable disease by Response Evaluation Criteria in Solid Tumors (RESIST) or clinically evaluable skin disease. Measurable lesions may be in the field of prior adjuvant irradiation; however, there must be at least an 8 week period between the last radiation treatment and the baseline scan documenting disease status for the lesion to be measurable.
  • Tumor that is accessible for biopsy.
  • Tumor that overexpresses ErbB2 defined as 3+ by IHC or FISH +. The ErbB 2 overexpression must be documented prior to dosing.
  • Documented disease progression or relapse following treatment, which must have contained a taxane and anthracycline-containing regimen in the adjuvant or metastatic setting (30 patients) plus trastuzumab (90 patients)
  • Histological diagnosis of breast carcinoma with a clinical diagnosis of IBC based on the presence of inflammatory changes in the involved breast, including diffuse erythema and edema (peau d'orange), with or without an underlying palpable mass involving the majority of the skin of the breast. Pathologic evidence of dermal lymphatic invasion should be noted but is not required for diagnosis.

Exclusion criteria:

  • Is clinically assessed to have inadequate venous access for protocol-related blood draws.
  • Has a clinically significant electrocardiogram (ECG) abnormality.
  • Has Class II to IV heart failure as defined by the New York Heart Association (NYHA) functional classification system.
  • Has physiological, familial, sociological, or geographical conditions that do not permit compliance with the protocol.
  • Is currently receiving oral steroid treatment (inhaled steroids are permitted), or any other medication on the prohibited medications list
  • Is currently receiving amiodarone or has received amiodarone in the 6 months prior to screening.
  • Has received chemotherapy, immunotherapy, biologic therapy or hormonal therapy within the past 14 days, with the exception of mitomycin C within the past 6 weeks.
  • Has received treatment with any investigational drug in the previous 4 weeks.

  • Is considered medically unfit for the study by the investigator as a result of the medical interview, physical exam, or screening investigations.
  • Has evidence of symptomatic or uncontrolled brain metastases or leptomeningeal disease. Patients with brain metastases treated by surgery and/or radiotherapy are eligible if neurologically stable and do not require steroids or anticonvulsants.
  • Has malabsorption syndrome, a disease affecting gastrointestinal function, or resection of the stomach or small bowel.
  • Is a pregnant or lactating female.
