1.There are 2 subjects (10961068 and 11631062) with AE records that have 
AEACN = DRUG WITHDRAWN, but they only have COMPLETED records in 
DS. Please explain.  
 
2.We have found that subject 11311279 was included in SDTM DM but not 
ADSL. Please explain.  
 
3.As previously communicated and discussed under BLA 125742 and other 
BLAs/INDs reactogenicity events that begin within the prespecified assessment 
period should have been reported in FACE and summarized with the subject diary data in CE. Since this was not implemented, we request that:
 
a.reactogenicity events that  begin within the prespecified assessment period 
that are currently reported in the AE dataset be included in FACE, and 
then be flagged in AE so that we know  that it is being included in the 
FACE dataset.  
b.Include all individual supporting a ssessments (daily e-diary and any 
unplanned assessments) and the assessor for each finding (identified 
using FAEVAL=STUDY SUBJECT or INVESTIGATOR) in the FACE domain.
 
c.Maintain one row per subject/vaccinat ion/symptom in the CE domain, with 
CE summarizing the duration of the event and maximum severity. Maximum severity (CESEV) should be based on the highest-level severity reported by the subject (via e-diary)  or investigator (in the unplanned 
assessment CRF).
 
d.Use SUPPCE CESEV1 and CEDIFFRS to show assessment of severity 
by study subject and reason investigator ’s assessment of severity differed 
from study subject as needed for events reported in CE.  
e.Update the analysis dataset(s) with records covering the entire event 
duration (which could go beyond the pr otocol-defined a ssessment period) 
with start/end dates and durations ( based on first and last days the 
symptom was present as recorded in the e-diary and/or Symptom 
Resolved Dates CRF) derived from both the e-diary and CRF data.
