- This type of contract encompasses the SU period up until SIVs.
- No SU activities can occur for a study until the SUA or SU WO have been signed.
- A SUA is used instead of a SU WO when a MSA has not been signed. You would prepare a SUA at SU when the Sponsor is rushed to get the study started, therefore the most necessary legal jargon is included that would normally be a part of the MSA.
