KADCYLA vs NEMLUVIO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KADCYLA (ado-trastuzumab emtansine) is an antibody-drug conjugate composed of trastuzumab, a humanized anti-HER2 antibody, linked to the microtubule inhibitor DM1 (maytansinoid). It binds to HER2 receptors on tumor cells, internalized via receptor-mediated endocytosis, and releases DM1 intracellularly, causing cell cycle arrest and apoptosis.
Nemolizumab is a humanized monoclonal antibody that binds to the interleukin-31 receptor alpha (IL-31RA), blocking IL-31 signaling. IL-31 is a cytokine involved in pruritus, inflammation, and barrier dysfunction in atopic dermatitis and other conditions.
3.6 mg/kg intravenously every 3 weeks until disease progression or unacceptable toxicity.
2 mg orally once daily.

Terminal half-life approximately 4 days (range 2.8-5.6 days), supporting every-3-week dosing.
The terminal elimination half-life is approximately 40 hours (range 35-50 hours), supporting once-daily dosing for sustained therapeutic effect.
Primarily hepatic metabolism with biliary excretion; minimal renal elimination (<10% unchanged).
Renal excretion of unchanged drug accounts for approximately 30% of the administered dose; fecal elimination via biliary excretion accounts for approximately 60%; the remainder is metabolized and excreted as metabolites.
