RATIONALE: Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PURPOSE: This randomized phase II trial is studying how well pemetrexed disodium or observation works in treating patients with malignant pleural mesothelioma without progressive disease after first-line chemotherapy.

|Start Date||April 2010|
|Anticipated Primary Completion Date||July 2017|
|Primary Outcome Measures||
Progression-free survival [Time Frame: Baseline up to 3 years]

Frequency of responses [Time Frame: Up to 3 years]
Toxicity [Time Frame: Baseline up to 3 years]
|Study Arms / Comparison Groups||2 / 0|
- To determine if maintenance therapy with pemetrexed disodium versus observation improves progression-free survival of patients with malignant pleural mesothelioma who have at least stable disease after completion of first-line therapy comprising pemetrexed disodium with cisplatin or carboplatin.
- To determine the overall survival of patients treated with this regimen versus observation.
- To evaluate the frequency of responses in patients treated with this regimen.
- To assess the toxicity of this regimen in these patients.
OUTLINE: This is a multicenter study. Patients are stratified according to first-line chemotherapy regimen (cisplatin/pemetrexed disodium vs carboplatin/pemetrexed disodium), histologic subtype (epithelioid vs other) and number of courses received (< 6 vs 6).
- Arm I: Patients receive pemetrexed disodium IV over 10 minutes on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients undergo observation until disease progression. After completion of study therapy, patients are followed up every 6 months for 3 years.

- No medical conditions that, in the opinion of the treating physician, would make study treatment unreasonably hazardous for the patient including, but not limited to, the following:
- Ongoing or active infection such as HIV positivity
- Inability to take oral medications
- Psychiatric illness/social situations that would limit compliance with study requirements
