Thymalin peptide complex conjugated with polyethylene glycol (PEG) polymer. PEGylation shields peptide from proteolytic degradation and renal clearance, dramatically extending half-life. Same thymic T-cell differentiation mechanism as standard thymalin but with sustained exposure kinetics.
Studies have administered: Experimental; optimal dosing under investigation; less frequent administration by design (weekly/biweekly vs daily)
Preclinical models: sustained immune restoration with weekly vs daily dosing. Equivalent immune parameters maintained. Longevity studies in aged mice show mortality reduction. Human clinical data not yet published.
PEGylation generally improves tolerability; anti-PEG antibodies theoretical concern with repeated PEG exposure; safety profile under investigation
