Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
Primary efficacy and safety analyses will occur when the last patient has achieved 8 weeks on study, including the 8-week bone marrow aspiration and biopsy. Follow-up for survival will
continue until all patients have either died or are lost to follow-up, or the Sponsor decides to end the trial, whichever occurs first. |
