TANDEM-1: Thrombolysis and Deferoxamine in Middle Cerebral Artery Occlusion
Study Details
Study Description
Brief Summary
Iron overload has been associated with greater brain injury in ischemia/reperfusion experimental stroke models and ischemic stroke patients, especially in those treated with thrombolytic treatment. Deferoxamine administration, an iron chelator, offers a neuroprotective action in ischemia/reperfusion animal models.
Primary objective: To evaluate the security and tolerability of deferoxamine endovenous treatment in acute ischemic stroke patients treated with iv. tPA.
Secondary objectives: To study pharmacokinetics of deferoxamine given by endovenous bolus (10 mg/Kg) followed by 72-hour continuous intravenous infusion (20, 40 o 60 mg/Kg). To evaluate the deferoxamine effect in clinical outcome, infarct volume and hemorrhagic transformation and brain edema development.
Methodology: Double-blind, randomized, placebo controlled, dose-finding phase II clinical trial. Study stages: 1st: bolus+20 mg/Kg/day vs. Placebo (n=15:5); 2nd: bolus+40 mg/Kg/day vs. Placebo (n=15:5); 3rd: bolus+60 mg/Kg/day vs placebo (n=15:5). These doses will be increased according to security results of the previous stage. Patients will be continuously monitored in stroke units. Laboratory parameters will be measured at baseline, 24h, 72h and 30 days to evaluate adverse events related to the drug. Serum deferoxamine and feroxamine concentrations will be measured along time after the injection in a subgroup of patients to the pharmacokinetics study. CT scan will be performed at 24-36h to assess hemorrhagic transformation and brain edema. The NIH Stroke Scale will be evaluated during hospitalization, and the Rankin score at discharge and 3 months.
If deferoxamine demonstrate to be secure and well tolerated treatment in acute stroke patients, it may be a new therapy option to lower the brain injury after ischemia and reperfusion.

| Active Comparator: 1. Deferoxamine Intravenous deferoxamine: bolus of 10mg/Kg (initiated during tPA infusion) and perfusion of 20/40/60 mg/Kg/day during 72h. Three different doses (3 steps), 15 patient in the active arm for each dose. |
Drug: Deferoxamine
Intravenous deferoxamine: bolus 10mg/Kg (initiated during thrombolytic infusion, iv tPA), followed by intravenous perfusion of 20/40/60mg/Kg during 72h. It's a dose-finding study with 3 different doses of deferoxamine, with 20 patients (15 active:5 placebo) in each step.
Bolus + 72h perfusion of saline solution for the placebo group.
|
| Placebo Comparator: 2. Placebo Saline solution: Bolus and perfusion during 72h. 5 patients in the placebo arm in each step (randomization 3:1) |
Drug: Deferoxamine
Intravenous deferoxamine: bolus 10mg/Kg (initiated during thrombolytic infusion, iv tPA), followed by intravenous perfusion of 20/40/60mg/Kg during 72h. It's a dose-finding study with 3 different doses of deferoxamine, with 20 patients (15 active:5 placebo) in each step.
Bolus + 72h perfusion of saline solution for the placebo group.
