Brief summary

The interest in using L-asparaginase in pancreatic cancer arose from in vitro and in vivo studies data showing an anti-neoplastic effect on pancreatic tumor cell lines. Interestingly, these studies suggest an additional effect of L-asparaginase associated to gemcitabine.GRASPA is a suspension of red blood cells encapsulating L-asparaginase. The aim of this phase I clinical trial is to evaluate the Maximum Tolerated Dose (MTD) of GRASPA on locally advanced or metastatic pancreatic tumors, after therapy failure of first or second line chemotherapy using gemcitabine.

Interventions

DRUGGRASPA

Each patient will receive one administration of GRASPA . A stepwise increase of 4 single doses of GRASPA will be administered to cohorts of 3 patients per dose

Participant flow

Recruitment details

Participants were recruited at 3 investigational sites in France between November 2009 and February 2011. The first participant was enrolled in the study on 27 November 2009 and the last patient exited the study on 30 March 2011.

Pre-assignment details

This was not a randomized study. No washout or run-in was required. Assignment of patients to treatment groups followed study design rules, per protocol.
