Template email for sponsors to confirm implementation of a modification

Last updated on 28 Apr 2026

This is an optional email template for sponsors to use to notify participating NHS organisations in England and Wales that a modification can be implemented. The notification should be sent to both the research management office and local research team, as well as the LCRN (Local Clinical Research Networks) for studies included on the NIHR (National Institute for Health Research) portfolio.

For category A and B modifications

This should be sent once all regulatory approvals are in place and HRA and HCRW Approval for the modification has been issued, and when the 35 calendar time limit has passed. This may be used ahead of the 35 calendar time limit if (a) HRA and HCRW Approval for the modification has been issued and (b) the site has confirmed it can implement the modification.

For category C modifications

This should be sent once all regulatory approvals are in place and HRA and HCRW Approval for the modification has been issued. Where HRA and HCRW Approval for the modification was confirmed in the confirmation of submission email, the sponsor should send the 'Template email for sponsors to share category C modification documents with sites' only.

The use of this template email will ensure clear and consistent communication between the sponsor and participating NHS organisations in England and Wales about implementation of modifications, and is intended to be sent as soon as the modification can be implemented.

Text that is highlighted in red should be amended by the sponsor as appropriate prior to issue of the email.

Please amend the text as appropriate where text is highlighted in bold (and instructions are given in brackets) prior to sending your email.
