The safety and tolerability of multiple doses of intravenously (IV) administered 131I-TM601 in adult patients with progressive and/or recurrent malignant glioma with measurable disease. Safety will be evaluated throughout the treatment and follow-up phase for all study patients; dose escalation decisions will be based on safety experience for each patient at 21 days following the final treament dose. [clinicaltrials_resource:89912f361e0e4ebfe3cd2a776381cdca]

In the first study phase (Dose Escalation), patients will be assigned to treatment to between 2-5 doses of 131I-TM601 treatment at a treatment dose of 1.2 mCi/kg of lean body mass (in scaled dosing, this will amount to 0.024 mg TM601 peptide/kg of lean body mass), once weekly (for between 2-5 weeks, depending upon dose cohort). The maximum amount of administered radioactivity per infusion is 100 mCi.
