- Registration Number
- NCT01521325
- Lead Sponsor
- Morphotek
- Brief Summary
This research is being conducted to determine the biodistribution of radiolabeled amatuximab in tumor and non-tumor tissues in subjects with mesothelin over expressing cancer including mesothelioma, pancreatic, ovarian or non small cell lung cancer.
- Detailed Description
The primary objective is to determine the biodistribution of radiolabeled amatuximab in tumor and nontumor tissues in subjects with mesothelin over-expressing cancers including mesothelioma, pancreatic, ovarian, and non small cell lung cancer. This is a single-center, single-dose, open-label, pilot study of amatuximab in approximately 20 subjects with mesothelin expressing tumors. 111Indium-radiolabeled amatuximab (5 mCi) will be administered. Serial SPECT imaging (at 3 specific time points up to 196 hours after cold infusion) will be performed to determine binding to tumor and nontumor tissue. Subjects will be observed closely for safety and possible development of anti-amatuximab antibodies. Pharmacokinetics of radiolabeled antibody will be determined with imaging over time.

- Primary Outcome Measures
Name Time Method Primary Objective: determine biodistribution of radiolabeled amatuximab in tumor and nontumor tissue 1 year To determine the biodistribution of radiolabeled amatuximab in tumor and nontumor tissue in subjects with mesothelin over expressing cancer including mesothelioma, pancreatic, ovarian or nonsmall cell lung cancer by performing SPECT imaging to determine binding to tumor and non-tumor tissue.
- Secondary Outcome Measures
Name Time Method Secondary objectives: determine the safety of a single IV of Indium-CHX-A amatuximab 1 year To determine the safety of a single IV of Indium-CHX-A amatuximab by collecting safety data during/ after the infusions as well as obtain any potential drug-related AEs 30 days post infusion
Pharmacokinetic and serum levels 1 year To determine the PK parameters of the Indium-CHX-A amatuximab with imaging, and serum levels collected over time
uptake of Indium-CHX-A amatuximab 1 year To explore the uptake of Indium-CHX-A amatuximab with mesothelin tumor expression as determined by ICH
occurrence of HACA 1 year To tabulate the occurrence of HACA which will be measured through serum samples collected over time
correlate shed serum mesothelin to imaging 1 year To correlate shed serum mesothelin to imaging obtained after antibody administration.
