AMG 102, Pemetrexed Disodium, and Cisplatin in Treating Patients With Malignant Pleural Mesothelioma

Primary Outcome Measures:

• To evaluate the progression-free survival of patients with malignant pleural mesothelioma (MPM) treated with anti-HGF monoclonal antibody AMG 102 in combination with pemetrexed disodium and cisplatin.

Secondary Outcome Measures:

• To assess the toxicity associated with this regimen in these patients.
• To determine the response rate of patients treated with this regimen.
• To determined the overall survival of patients treated with this regimen.
• To evaluate multiple potential correlative biomarkers in MPM that are relevant to this combined regimen, including serum HGF and mesothelin levels, c-met expression by IHC in tumor specimens, presence of c-met mutations in tumor, and the presence of thymidylate synthetase (TS) and excision repair cross complementing protein-1 (ERCC1) polymorphisms.

Detailed Description:

Outline: This is a multicenter study.

Patients receive anti-HGF monoclonal antibody AMG 102 (AMG 102) IV over 1 hour, pemetrexed disodium IV over 10 minutes, and cisplatin IV over 1 hour on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients without disease progression may continue AMG 102 IV over 1 hour on day 1, every 3 weeks, as maintenance therapy in the absence of disease progression.

Some patients undergo blood sample collection at baseline and periodically during study for correlative biomarker studies. Tumor samples from diagnostic tissue may also be analyzed.

After completion of study therapy, patients are followed up periodically every 3 months for 2 years and then every 6 months for 1 year.
