Can the sponsor delete null MHTERM/AETERM/CMTRT data?

Hi, this is MinJi.

In large subjects study (e.g. phase 3), there are some cases in which blank rows in AE/MH/CM eCRF DB were collected.

In this case, to remove validation findings, can the sponsor delete null MHTERM/AETERM/CMTRT data?

Thank you for your help!

Best regards,

MinJi
