Any research proposal involving a collaboration with one or more industrial partners (contributing either in cash or in kind) is handled by MRC as a MICA. MICA is not a scheme in itself, but a mechanism to support the establishment of an agreement between academic and industry research partners.
Each proposal that involves such industrial collaboration will need to include a MICA form and also a heads of terms, which will need to be signed by each collaborator to confirm that they are willing to collaborate for the duration of the study. See the MRC guidance on industry and collaborations for more relating to these attachments.
