Clinical Trials

Pemetrexed Disodium or Observation in Treating Patients With Malignant Pleural Mesothelioma Without Progressive Disease After First-Line Chemotherapy

Location:

Rochester,  MN

Trial status:

Open for Enrollment

Why is this study being done?

OBJECTIVES:

Primary

- 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.

Secondary

- 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.

Who is eligible to participate?

DISEASE CHARACTERISTICS:

- 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
