Primary Outcome Measures:
- To determine the response to the combination of bevacizumab and erlotinib in previously treated malignant mesothelioma [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- To determine the time to tumor progression [ Time Frame: TBD ] [ Designated as safety issue: No ]
- to determine the duration of response [ Time Frame: TBD ] [ Designated as safety issue: No ]
- to determine the median and overall survival of patients [ Time Frame: TBD ] [ Designated as safety issue: No ]
- to determine the safety of the drugs administered [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
Intervention Details:
Drug: Erlotinib
Taken orally once daily. Participants may continue on study treatment until disease progresses or they experience serious side effects.
Drug: Bevacizumab
Given intravenously over 30-90 minutes, on day 1 of each 21-day cycle. Participants may continue on study treatment until disease progresses or they experience serious side effects.
Each cycle of study treatment lasts 21 days. The patient will take erlotinib by mouth once daily. On day 1 of every cycle, the patient will receive bevacizumab intravenously over a 30-90 minute time period.
CT scan(s), MRI(s) and/or x-ray(s) of the cancer site will be performed every 6 weeks (2 cycles) to assess the extent of the response to treatment.
Bloodwork will be performed before the first dose of erlotinib and bevacizumab at Cycle 1, Cycle 2, Cycle 3, and at the end of treatment.
At the completion of the treatment a physical exam, vital signs, blood tests, urine tests and standard radiologic testing will be performed.
The duration of study depends upon how the patients' mesothelioma responds to treatment as well as how well the patient tolerates the medication.
