RE:Dose Escalation QuestionThe way I understood from M. Dubuc is that first patient received a very very light dosage so they can evaluate the side effect. The second patient was supposed to receive the double dose of what the first patient received. The third patient should receive the double dose of what the second patient received and so on until they find and determine the best dosage for all based on side effect. That was my understanding.

From the description, it looks like the former but it's not entierly clear the way it's worded. So Patient #1 if he passed the exam, got a higher dosage for his second round. Patient #2 will start at the same beginning dose and then also escalate. Is that correct?
From the clinical trial site:
" Dose escalation by dose-doubling will be done for the first 2 dose levels, followed by a modified Fibonacci dose escalation scheme (i.e. dose increases of 67%, 50%, 40% and 33%) thereafter for each dose level. Patients in Part 1 will be observed for 21 days post Cycle 1 Day 1 drug administration for dose limiting toxicity (DLT). Dose escalation to the next dose level will proceed following satisfactory review of safety data until the MTD is reached. The MTD is defined as that dose-level at which ≤1 of 6 patients in a cohort develop an emergent DLT."
