Buc, yes, I think you are correct, and like Plotinus, I think the treatment waters will part earlier. The trial length for each patient is "From enrolment (misspelled at clinical trials.gov, although that spelling saves time, ink, paper and wear and tear on the government typewriters) through end of treatment at 12 months".
My suffering and frustration as a long time long pale in comparison to the angst and horror experienced by patients with metastases. Good Luck to them and us!
