S0722: Everolimus in Treating Patients With Pleural Malignant Mesothelioma That Cannot Be Removed By Surgery

Brief Summary

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase II trial is studying how well everolimus works in treating patients with pleural malignant mesothelioma that cannot be removed by surgery.

Descriptive Information
PhasePhase 2
Study TypeInterventional
  • Malignant Mesothelioma
  • Drug: everolimus
Study Arms / Comparison Groups1 / 0
Detailed Description



- To determine the 4-month progression-free survival in patients with unresectable malignant pleural mesothelioma treated with everolimus.


- To determine the response rate (confirmed and unconfirmed, complete and partial responses) and disease control rate (response or stable disease) in patients with measurable disease by RECIST and modified RECIST criteria.

- To determine overall survival of these patients.

- To evaluate the frequency and severity of toxicities associated with this treatment regimen.

OUTLINE: This is a multicenter study.

Patients receive oral everolimus once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed for 3 years.
