  • *. When a sponsor that generally submits Research INDs, submits either a Phase 2 or Phase 3 protocol, they should select "Commercial" (eCTD requirements will apply). However, when the sponsor believes the Phase 2 or Phase 3 protocol is still solely for research, the sponsor may submit a justification explaining their rationale in the IND cover letter, along with the protocol. If the FDA agrees, then the IND will remain a “Research” IND and the eCTD requirements will not apply. Note that in all cases, expanded access INDs and protocols should be marked as “Research” on the Form 1571 and are exempt from eCTD requirements.
