NAFAZAIR vs TARPEYO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unknown. It is a purified fatty acid derivative that may modulate inflammatory responses.
TARPEYO (budesonide) is a corticosteroid with anti-inflammatory activity. It acts by binding to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines and immune cell activation, thereby reducing proteinuria in IgA nephropathy.
2.5 mg subcutaneously once daily.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

Terminal elimination half-life is 6-8 hours; in moderate renal impairment (CrCl 30-50 mL/min) extends to 12-15 hours.
Terminal elimination half-life is approximately 27.3 hours (range 21-36 hours) in patients with IgA nephropathy. This supports once-weekly subcutaneous dosing without dose adjustment over the dosing interval.
Primarily renal excretion (70-80% as unchanged drug), with 15-20% fecal elimination via biliary secretion.
Primarily hepatic metabolism, with <1% excreted unchanged in urine and <1% in feces. Elimination is predominantly via biliary excretion of metabolites into feces, accounting for >90% of total clearance.
