ARA-290
Cibinetide · Pyroglutamate helix B surface peptide · et al.
ARA-290 is a rare design success — eleven amino acids drawn from erythropoietin's helix B that engage the tissue-protective receptor without touching the hematopoietic one — paired with a clinical-development program that produced legitimate Phase II signals and then stalled before any Phase III.
Half-life·~20 minutes terminal plasma half-life on subcutaneous admini…

LL-37
Cathelicidin · hCAP-18 · et al.
LL-37 is the textbook endogenous antimicrobial peptide and the molecular bridge between the vitamin D literature and innate immunity — and the same biology that makes it interesting in chronic infection also implicates it in psoriasis, lupus, and rosacea pathology. Gray-market subcutaneous use lacks both an efficacy database and a clean safety record.
Half-life·Plasma half-life of native LL-37 is short — minutes — owing …

Vasoactive Intestinal Peptide
VIP · vasoactive intestinal peptide · et al.
VIP is a real neuropeptide with characterised receptor pharmacology, the most-rigorously-tested peptide in COVID-19 acute respiratory distress — and the most-rigorous trial program ended with negative primary endpoints and an FDA EUA rejection, while the parallel off-label CIRS and long-COVID use case has accumulated practitioner observation but no controlled-trial support.
Half-life·Plasma half-life is short — approximately two minutes — whic…
