Hydrostatic pressure response of $\mathrm{LaAu}{\mathrm{Sb}}_{2}$ charge density wave (CDW) system is investigated using electrical transport, x-ray diffraction (XRD), and density-functional theory (DFT). Resistivity data at ambient evidence a clear CDW transition 83 K. X-ray reveals that in plane out axes show opposite behavior with decreasing temperature, particular, $c$ axis develops distinct change \ensuremath{\sim}250 K, much above the observed The shifts to low temperature increasing pressure. Our resistivity indicate complete suppression \ensuremath{\sim}3.6 GPa. High-pressure XRD revealed from linear trend for ($c$) ($a$) lattice parameters 3.8 With compression, DFT indicated an anomaly c/a ratio around 8 calculated electronic structure also minor changes band this range. In addition, high-pressure structural investigations reveal be stable up pressures as high 150
