(S)-3-(4-(2-((3-fluorophenyl)amino)-2-oxoethyl)piperazin-1-yl)-N,N-dimethylpropanamide; selectively inhibits the interaction between the PD-1/PD-L1 immune checkpoint, blocking the PD-1/PD-L1 pathway and restoring antitumor T-cell function.
WERA is a serotonin-norepinephrine reuptake inhibitor (SNRI) that inhibits the reuptake of serotonin and norepinephrine, enhancing neurotransmission in the central nervous system.

12–18 hours (terminal). Steady-state achieved in ~3 days. Extended to ~30 hours in severe renal impairment.
The terminal elimination half-life of WERA is approximately 4-6 hours in patients with normal renal function. This relatively short half-life supports twice-daily dosing, but requires dose adjustment in renal impairment.
Primarily renal (60–70% unchanged), with 20–30% biliary/fecal, and <10% metabolized. Dosage adjustment required in renal impairment.
WERA is predominantly eliminated via the renal route, with approximately 60-70% of the dose excreted unchanged in the urine. Biliary/fecal excretion accounts for 20-30% of elimination, primarily as metabolites. Less than 10% is eliminated via other routes.
