(1) (Professional Graphics Adapter) An early IBM PC display standard for 3D processing with 640x480x256 resolution. It was not widely used. See CGA, EGA and VGA.

(2) (Programmable Gate Array) See gate array and FPGA.

(3) (Pin Grid Array) A square chip package with a high density of pins (200 pins can fit in 1.5" square), enabling it to support a large amount of I/O. PGAs are typically ceramic (CPGA), but plastic cases are also used (PPGA). The underside of a PGA package looks like a "bed of nails." In a staggered PGA (SPGA), the pins do not line up in perfect rows and columns. See ZIF socket.

The primary endpoints of the first phase are at least a 90% improvement in the Psoriasis and Severity Index (PASI 90) and a static Physician Global Assessment (sPGA) score of clear or almost clear (sPGA 0/1) in comparison to placebo.
