ORTIKOS vs STERANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ORTIKOS (acalabrutinib) is a selective, irreversible inhibitor of Bruton tyrosine kinase (BTK). It forms a covalent bond with the active site cysteine residue (Cys481) in BTK, blocking downstream B-cell receptor signaling and inhibiting malignant B-cell proliferation and survival.
Sterane (prednisolone) is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.

Terminal half-life of 8 hours (range 6-10) in healthy adults; prolonged to 24 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 2.5 hours (range 2-3 hours) in adults with normal renal function; clinically, this supports twice-daily dosing
