The only registered human programme is TRIIM-X (NCT04375657, phase 2, about 85 participants, growth hormone plus metformin and DHEA, thymic density by MRI/CT), an extension of the 9-man TRIIM pilot whose results were explicitly preliminary and are not independently replicated; its interim reports come from the sponsor (https://classic.clinicaltrials.gov/ct2/show/record/NCT04375657). Regenerative candidates remain earlier: KGF/palifermin is in transplant and MS trials rather than approved for age-related involution, IL-22 and BMP4 are preclinical (https://pmc.ncbi.nlm.nih.gov/articles/PMC8652142/table/T1), and Tolerance Bio's iPSC-derived thymic organoids are preclinical with pre-IND work planned (https://secure.businesswire.com/news/home/20251027232982/en/). No open-source or openly published method restores a human thymus, so this is open work, but tasks replicating TRIIM-style regimens are not new and need their own basis.
