Brief summary

Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. This phase II trial is studying how well lapatinib works in treating patients with persistent or recurrent ovarian epithelial or peritoneal cancer.

Detailed description

OBJECTIVES: Primary I. Determine 6-month progression-free survival of patients with persistent or recurrent ovarian epithelial or primary peritoneal cancer treated with lapatinib. II. Determine the nature and degree of toxicity of this drug in these patients. Secondary I. Determine the clinical response rate (partial and complete response) in patients treated with this drug. II. Determine the duration of progression-free and overall survival of patients treated with this drug. III. Determine the impact of prognostic variables, including platinum sensitivity, performance status, and cellular histology (clear cell or mucinous type), on patients treated with this drug. IV. Correlate tumor levels of expression of epidermal growth factor receptors (EGFR), phosphorylated EGFR, HER2/neu, and Ki-67, as determined by immunohistochemistry, with clinical response in patients treated with this drug. V. Correlate EGFR mutations in tumor DNA with clinical response in patients treated with this drug. OUTLINE: This is a multicenter study. Patients receive oral lapatinib once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study therapy, patients are followed every 3 months for 2 years and then every 6 months for 3 years. PROJECTED ACCRUAL: A total of 22-60 patients will be accrued for this study within 12-26 months.

Design outcomes

Primary

MeasureTime frameDescription
Progression-free Survival (PFS) > 6 MonthsFor those patients whose disease can be evaluated by physical examination, progression was assessed prior to each 28-day cycle. CT scan or MRI if used to follow measurable disease every other cycle for the first 6 monthsProgression is defined according to RECIST v1.0 as at least a 20% increase in the sum of LD target lesions taking as reference the smallest sum LD recorded since study entry, the appearance of one or more new lesions, death due to disease without prior objective documentation of progression, global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression, or unequivocal progression of existing non-target lesions.
Frequency and Severity of Adverse Effects as Assessed by Common Toxicity Criteria for Adverse Events (CTCAE) v3.0Assessed every cycle while on treatment, 30 days after the last cycle of treatment

Secondary

MeasureTime frameDescription
Overall SurvivalFrom entry into the study to death or the date of last contact, assessed up to 5 yearsThe observed length of life from entry into the study to death or the date of last contact.
Prognostic Variable: Platinum SensitivityBaselinePatients who had disease progression within 6 months of ending their last regimen of platinum therapy were considered platinum resistant. Patients who had disease progression between 6 and 12 months of ending their last platinum regimen were considered platinum sensitive. Patients who had disease progression beyond12 months of ending their last platinum regimen were also considered platinum sensitive.
Tumor ResponseBaseline, every other cycle for 6 months and then every 6 months for up to 5 yearsRECIST 1.0 defines complete response as the disappearance of all target lesions and non-target lesions and no evidence of new lesions documented by two disease assessments at least 4 weeks apart. Partial response is defined as at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions taking as reference the baseline sum of LD. There can be no unequivocal progression of non-target lesions and no new lesions. Documentation by two disease assessments at least 4 weeks apart is required. In the case where the ONLY target lesion is a solitary pelvic mass measured by physical exam, which is not radiographically measurable, a 50% decrease in the LD is required. These patients will have their response classified according to the definitions stated above. Complete and partial responses are included in the objective tumor response rate.
Prognostic Variable: Cellular HistologyBaselineNumber of patients with Clear Cell Carcinoma or Mucinous Carcinoma
Prognostic Variables: Performance StatusBaselinePerformance Status 0 = Fully active, able to carry on all pre-disease performance without restriction Performance Status 1 = Restricted in physically strenuous activity but ambulatory and able to carry out work of light or sedentary nature, e.g., light housework, office work Performance Status 2 = Ambulatory and capable of all self care but unable to carry out any work activities. Up and about more than 50% of waking hours.
Duration of Progression-free SurvivalEvery other cycle for 6 months and then every 6 months for up to 5 years.Progression is defined according to RECIST v1.0 as at least a 20% increase in the sum of LD target lesions taking as reference the smallest sum LD recorded since study entry, the appearance of one or more new lesions, death due to disease without prior objective documentation of progression, global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression, or unequivocal progression of existing non-target lesions.

Progression-free Survival (PFS) > 6 Months

Progression is defined according to RECIST v1.0 as at least a 20% increase in the sum of LD target lesions taking as reference the smallest sum LD recorded since study entry, the appearance of one or more new lesions, death due to disease without prior objective documentation of progression, global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression, or unequivocal progression of existing non-target lesions.

Time frame: For those patients whose disease can be evaluated by physical examination, progression was assessed prior to each 28-day cycle. CT scan or MRI if used to follow measurable disease every other cycle for the first 6 months
