The current Northwestern study is presently described as a dosage study. Is this dose range (below) lower than the the one you chose? May I ask what dosage you did choose?

"The initial phase of this study will be a dose escalation trial of 3-6 patients per each dose level. Dose escalation will occur until the MTD or the maximal defined dose (MDD) (40 mg) is reached. The starting dose will be 10 mg for cohort 1, 20 mg for cohort 2, 30 mg for cohort 3 and 40 mg for cohort 4. Patients will be treated twice a week for 4 weeks, then once a week for 4 weeks, and then every 2 weeks. The starting dose is based on the safety of this dose and higher doses as reported in the literature. The MTD or MDD will be used for phase II."

Certainly my priority is to avoid WBRT as long as possible.
