The NCI Drug Dictionary contains technical definitions and synonyms for drugs/agents used to treat patients with cancer or conditions related to cancer. Each drug entry includes links to check for clinical trials listed in NCI's List of Cancer Clinical Trials.

semuloparin
An ultralow-molecular-weight heparin (ULMWH) (Mw: 2000-3000 daltons) consisting of a polydisperse mixture of oligomeric heparin fragments with potential anticoagulant activity. Semuloparin binds to and activates antithrombin III (ATIII), which may result in the inhibition of activated factor Xa and, to a much lesser extent, factor IIa (thrombin) and so the inhibition of fibrin formation. Compared to low-molecular-weight heparins (LMWHs), AVE5026 exhibits an even higher ratio of anti-Factor Xa to anti-Factor IIa activity (>30:1). Compared to unfractionated heparins, the use of LMWHs is associated with lower incidences of major bleeding, osteoporosis and heparin-induced thrombocytopenia. Like LMWHs, this agent may inhibit tumor growth by regulating angiogenesis and apoptosis. AVE5026 is prepared by partial depolymerization of unfractionated porcine mucosal heparin. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
