NCI Drug Dictionary
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.
- nab-paclitaxel/rituximab-coated nanoparticle AR160 [ Abraxane/Rituxan 160 complex; Abraxane coated with rituximab; Abraxane Coated with rituximab 160nm nanoparticle ]
- A formulation composed of nanoparticle albumin-bound (nab) paclitaxel, which is an albumin-stabilized nanoparticle containing the natural taxane paclitaxel, non-covalently coated with rituximab, a recombinant chimeric murine/human antibody directed against the CD20 antigen found on B-lymphocytes, with potential antineoplastic activity. Upon administration of nab-paclitaxel/rituximab nanoparticle AR160, the rituximab moiety specifically binds to CD20 and targets this formulation to CD20-positive tumor cells. Paclitaxel binds to and stabilizes microtubules, which prevents depolymerization and inhibits cellular motility, mitosis, and replication. This leads to cell death of the CD20-expressing tumor cells that were targeted by this agent. The combination of albumin-stabilization and rituximab-targeting allows for higher efficacy and decreased paclitaxel-induced toxicity as it specifically targets CD20-expressing tumor cells. Rituximab may also induce complement-dependent cytotoxicity and antibody-dependent cellular toxicity. Check for active clinical trials using this agent. (NCI Thesaurus)
- paclitaxel albumin-stabilized nanoparticle formulation [ Abraxane ]
- A Cremophor EL-free, albumin-stabilized nanoparticle formulation of the natural taxane paclitaxel with antineoplastic activity. Paclitaxel binds to and stabilizes microtubules, preventing their depolymerization and so inhibiting cellular motility, mitosis, and replication. This formulation solubilizes paclitaxel without the use of the solvent Cremophor, thereby permitting the administration of larger doses of paclitaxel while avoiding the toxic effects associated with Cremophor. Check for active clinical trials using this agent. (NCI Thesaurus)
