Chimeric antibodies specific to human CD4 antigen, DNA encoding, pharmaceutical compositions containing and use thereof as therapeutic agents are taught. These chimeric antibodies contain Old World monkey variable sequences and human constant domain sequences, preferably human gamma 1, gamma 4 or mutated forms thereof. These antibodies possess desirable therapeutic properties including low antigenicity, reduced (or absent) T cell depleting activity, good affinity to human CD4 and enhanced stability (in vivo half-life).
