The present invention relates, in general, to agents that modulate the pharmacological activity of nucleic acid molecules and, in particular, to agents that bind therapeutic or diagnostic nucleic acid molecules in a sequence independent manner and modulate (e.g., inhibit or reverse) their activity. The invention also relates to compositions comprising such agents and to methods of using same.

Method of modulating the activity of a nucleic acid molecule

The present invention relates, in general, to receptors and to platelet aggregation and, in particular, to a method of inhibiting platelet aggregation using an aptamer that binds to and inhibits the activity of a receptor, such as glycoprotein IIb/IIIa (gpIIb/IIIa), and to aptamers suitable for use in such a method. The invention also relates to antidotes to antiplatelet agents and to methods of using such antidotes to reverse aptamer-induced platelet inhibition. The invention further relates to von Willebrand Factor (VWF) inhibitors, and antidotes therefore, and to methods of using same.

Reversible platelet inhibition

Focused aptamer libraries are constructed in accordance with a proteome (i.e., complex mixture of native biomolecules). The libraries may be screened to identify one or more candidate aptamers with desired biological activities other than specific binding to a target. Aptamers which are selected or derivatives thereof may be used for those specific activities in biological systems. Any combination of deconvoluting a focused library (functional profiling), increasing frequencies of particular aptamers in a focused library (Laser SELEX), and decreasing frequencies of particular aptamers in a focused library (DeSELEX) may be performed prior to assaying biological activity.
