JAYPIRCA vs TECHNESCAN GLUCEPTATE
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-99m glucepstate is a radiopharmaceutical that localizes in renal cortex and urinary tract via glomerular filtration and tubular secretion. In the brain, it accumulates in areas of disrupted blood-brain barrier, such as tumors, infarcts, or abscesses, due to increased vascular permeability and binding to intracellular components.
The recommended adult dose is 15 mg orally once daily, with or without food.
For brain imaging: 555-740 MBq (15-20 mCi) intravenously, single dose. For kidney imaging: 111-370 MBq (3-10 mCi) intravenously, single dose.

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: 2-4 hours; allows rapid renal clearance and minimal background interference for imaging.
Primarily renal (80-90% as unchanged drug and minor metabolites); fecal <5%.
Renal: >90% of injected dose excreted via glomerular filtration within 24 hours; biliary/fecal: <5%.
