JAYPIRCA vs NEPHROSCAN
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.
Calcium trisodium pentetate (NEPHROSCAN) chelates gadolinium ions by forming a stable complex with the metal, thereby reducing the toxicity and enhancing elimination of gadolinium from the body. It acts as a decorporation agent for gadolinium.
The recommended adult dose is 15 mg orally once daily, with or without food.
1 to 5 mCi (37 to 185 MBq) as a single intravenous injection for renal imaging.

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 elimination half-life: 1.6 hours in normal renal function; prolonged to >20 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal (80-90% as unchanged drug and minor metabolites); fecal <5%.
Renal: 95% as unchanged drug via glomerular filtration; no biliary/fecal excretion.
