At 2.72 GPa between 88 and 98$%$ of the superconducting T$^\\prime$ phase \\cite{Tprime} of the optimally doped Pr$_{1.85}$Ce$_{0.15}$CuO$_{4}$ transforms into the insulating phase T. The T$_{c}$ of the remaining 2-12$%$ T$^\\prime$ phase is suppressed continuously from 22 K to 18.5 K at about 14 GPa.
