The NCI has published a Notice of Special Interest for competitive revisions and administrative supplements for COVID-19 research:
NOT-CA-20-042 Notice of Special Interest (NOSI): National Cancer Institute Announcement Regarding Availability of Urgent Competitive Revision and Administrative Supplements on Coronavirus Disease 2019 (COVID-19).
A list of eligible mechanisms is included in the announcement.
The Cancer Center Support Grant P30 is eligible. All applications for the P30 should be for supplemental funds, not competitive revisions. If you are interested in being considered for a P30 administrative supplement on COVID-19, please contact DF/HCC (firstname.lastname@example.org) with a brief, one-page summary of your proposed project. The most meritorious proposals will be submitted to NCI for consideration, on a rolling basis.
The potential for immediate impact, cancer relevance, and feasibility will be important considerations for funding.
