Where Selank stands today
No FDA-approved drug contains selank. FDA placed selank acetate in 503A Category 2 in September 2023 and removed it in September 2024 because the nominator said it had meant to nominate a different substance. It has had no advisory committee review, is not on the 503A or 503B bulks list, is in no category, and is not in HHS's October 2026 interim policy.
For pharmacies compounding one patient's prescription (section 503A)
Not in any 503A category and not on the 503A bulks list. Removed from Category 2 in September 2024 because the nominator said it meant to nominate a different substance; no advisory committee review. Not in HHS's Oct 2026 interim policy.
“Bulk drug substances nominated but withdrawn ... Selank acetate (TP-7) Compounded drugs containing selank acetate may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities.”
““Selank acetate (TP-7)” has been removed from Category 2 because FDA received additional information from the nominator indicating that they intended to nominate a different bulk drug substance.”
FDA interim 503A bulks policy: a substance outside Category 1 gets no interim enforcement discretion
“Drug products compounded using a bulk drug substance for which each of the above circumstances are not present are not within the scope of the policy described in this guidance.”
For outsourcing facilities (section 503B)
Not on the 503B bulks list and not in any 503B category (FDA's 503B nominations list, updated March 21, 2025, does not name it)
“Outsourcing facilities, which operate under section 503B of the Federal Food, Drug, and Cosmetic Act (FD&C Act), may not compound a drug product that includes a bulk drug substance unless: The bulk drug substance appears on a list identifying bulk drug substances for which there is a clinical need (the 503B bulks list), or”
The 503B bulks list holds five substances (diphenylcyclopropenone, glycolic acid, quinacrine HCl oral, squaric acid dibutyl ester, trichloroacetic acid); none of the compounds in this file
“FDA has evaluated the following bulk drug substances and determined that there is a clinical need for outsourcing facilities to compound drug products using these bulk drug substances under section 503B of the FD&C Act:”
