Pilot Study of Bisphosphonate Therapy (Zoledronic Acid) in Patients With Malignant Mesothelioma (UAB 0901)

Published: September 17, 2010

Detailed Description:

This pilot study will examine the effect of bisphosphonate (zoledronic acid) in patients with malignant mesothelioma. Evaluation will be limited to patients with standard (CT scans) and functional instruments (FDG PET Scans) of tumor assessment after the administration of standard doses of zoledronic acid (4 mg IV every 3 weeks). We will also explore the biologic effect of zoledronic acid in patients using new serum markers as well as several blood level markers.

Primary Outcome Measures:

Evaluation of the tumor response rate following zoledronic acid
[ Time Frame: CT and/or PET scans will be performed to measure tumor size approximately every 56 days until there is tumor growth ] [ Designated as safety issue: Yes ]
The best objective response from either the modified RECIST (CT scan) or the Metabloic Response (PET scan) efficacy method of evaluation will be used to determine the first evaluation after 2 cycles of treatment. In subsequent evaluations for response, modified RECIST with CT scans will be the only instrument to evaluate the response to therapy.

Secondary Outcome Measures:

Evaluation of the duration of tumor response
[ Time Frame: Assessments approximately every 8 weeks for the patient’s life ] [ Designated as safety issue: No ]
The patient’s medical condition will be followed for the rest of their lives with continued CT scans being performed every 8 weeks to document tumor growth while off of the study medication.
