UC5:Assigning of Epoch after treatment discontinuation (NS) Study epochs per protocol: ScreeningTreatmentFollow up Randomization Treatment start End of treatment, Date of last trt End of study, consent withdraw
UC5: (cont.) subject information CRF pages: end of treatment, FU, end of study Subject has got 2 cycles. Last TRTDTC=2014-02-01 Cycle 3 should start at 2014-02-21, but subject has AE, thus treatment delay, No bettering after 14 days, Lab visit, EG Visit performed. => Physician decision to discontinue treatment Subject comes to visit and decide not to go to FU, but to withdraw consent at 2014-03-14, so no FU observation and data collection, end of study. Q: Which epoch and VISITNUM to assign to LB and EG visit in delay period?
