The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to cell in vivo. The pharmacokinetic modulator improve in vivo targeting compared to the targeting ligand alone. Targeting ligand-pharmacokinetic modulator targeting moiety targeted RNAi polynucleotides can be administered in vivo alone or together with co-targeted delivery polymers.
