Summary
Brief summary (as posted)
This phase II trial is studying how well lapatinib works in treating patients with recurrent or persistent endometrial cancer. Lapatinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth

Arms and outcomes
Arms (1)
- type
- EXPERIMENTAL
- label
- Treatment (lapatinib ditosylate)
- description
- Patients receive oral lapatinib once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- interventionNames
- Drug: lapatinib ditosylate
Primary outcomes (2)
- measure
- Percentage of Patients With Progression-free Survival > 6 Months
- timeFrame
- 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 lesion for measurable disease every other cycle, for up to 5 years.
- description
- 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.

* Negative pregnancy test
* Fertile patients must use effective contraception
* No active infection requiring antibiotics
* No sensory or motor neuropathy \> grade 1
* No history of allergic reaction attributed to compounds of similar chemical or biological composition to lapatinib
* No other invasive malignancy within the past 5 years except nonmelanoma skin cancer
* At least 4 weeks since prior immunologic agents for the malignant tumor
* No prior trastuzumab (Herceptin\^®) or any target-specific therapy directed to the HER family (e.g., gefitinib, erlotinib, or cetuximab)
* At least 6 weeks since prior nitrosoureas or mitomycin for the malignant tumor and recovered
* No prior non-cytotoxic chemotherapy for recurrent or persistent disease
* At least 1 week since prior hormonal therapy for the malignant tumor
* Concurrent hormone replacement therapy allowed
* Recovered from prior radiotherapy
* Recovered from prior surgery
* No prior surgery affecting absorption
* At least 4 weeks since other prior therapy for the malignant tumor
* No prior lapatinib
* No prior anticancer treatment that would preclude study treatment
* Concurrent oral anticoagulants (e.g., warfarin) allowed provided there is increased monitoring of INR
* No concurrent CYP3A4 inducers or inhibitors
* No concurrent combination antiretroviral therapy for HIV-positive patientsReferences
