INCASSIA vs SELFEMRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
INCASSIA (bleomycin) is an antineoplastic antibiotic that causes DNA strand breaks through free radical generation, inhibiting DNA synthesis and cell division.
Selective estrogen receptor degrader (SERD) that binds to estrogen receptor alpha (ERα), inducing its degradation and inhibiting estrogen-dependent cell proliferation.

Terminal elimination half-life is 8-12 hours in adults with normal renal function. This supports twice-daily dosing, though dose adjustment is required in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life of 12-16 hours in healthy adults; prolonged to 24-36 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of unchanged drug accounts for approximately 60-70% of the administered dose, with biliary/fecal elimination contributing about 20-30%. Less than 10% is metabolized.
Primarily renal excretion as unchanged drug (50-60%) and metabolites (20-30%); biliary/fecal elimination accounts for 10-15%.
