JAYPIRCA vs TECHNETIUM TC 99M TSC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
JAYPIRCA (pirtobrutinib) is a selective, non-covalent (reversible) inhibitor of Bruton's tyrosine kinase (BTK). It binds to BTK, inhibiting its kinase activity, thereby blocking B-cell receptor signaling and reducing proliferation and survival of malignant B cells.
Technetium Tc 99m TSC is a radiopharmaceutical that binds to activated leukocytes, primarily neutrophils, via interaction with integrin receptors (e.g., CD11b/CD18), allowing imaging of inflammation and infection.
The recommended adult dose is 15 mg orally once daily, with or without food.
1-10 mCi (37-370 MBq) intravenously as a single dose for imaging studies; dose depends on indication and imaging protocol.

Terminal half-life approximately 15-20 hours in adults with normal renal function; prolonged in renal impairment (up to 30-40 hours in severe impairment).
Terminal half-life approximately 6 hours; allows for same-day imaging but requires prompt scanning due to radionuclide decay.
Primarily renal (80-90% as unchanged drug and minor metabolites); fecal <5%.
Renal: ~50% excreted unchanged in urine within 24 hours; remainder eliminated via hepatobiliary system into feces.
