20110015244 | BENDAMUSTINE AMPHIPHILIC ANIONIC COMPOSITIONS - The present invention is directed to pharmaceutical compositions comprising bendamustine and one or more amphiphilic anionic compounds and self assembled aggregates, which aggregates exhibit enhanced stability in aqueous solutions, including plasma, are disclosed. The unexpectedly enhanced stability afforded by such aggregates permits patients to be treated with bendamustine in lower and/or with less frequent dosages or to improve its therapeutic effect while using the same as presently used treatment protocol. | 01-20-2011 |
20110015245 | BENDAMUSTINE AMPHIPHILIC CATIONIC COMPOSITIONS - The present invention is directed to pharmaceutical compositions comprising bendamustine and one or more amphiphilic cationic compounds, which self assemble to form aggregates. The exhibiting enhanced stability in aqueous solutions, including plasma. The unexpectedly enhanced stability afforded by such aggregates permits patients to be treated with bendamustine in lower and/or with less frequent dosages or to improve its therapeutic effect while using the same as presently used treatment protocol. | 01-20-2011 |
20110207760 | SN-38 COMPOSITIONS - In one aspect, the present invention is directed to a stable aqueous composition including (a) SN-38; (b) a sulfoalkyl derivative of a cyclodextrin; and (c) water; in which the concentration of SN-38 in the composition is at least about 0.13 mg/g of the composition. In another aspect, this invention is directed to a process for making the composition which process comprises mixing SN-38 and a sulfoalkyl derivative of a cyclodextrin in an aqueous medium wherein the water content of the mixture is less than about 60% by weight. | 08-25-2011 |
20110207764 | CYCLOPOLYSACCHARIDE COMPOSITIONS - The present invention is directed to a composition including: (a) an active ingredient other than bendamustine; (b) a charged cyclopolysaccharide comprising at least one charged group; and (c) a stabilizing agent comprising at least one charged group having a charge opposite to that of the cyclopolysaccharide. The composition provides unexpectedly desirable stability in reactive environments such as plasma which contain entities (such as enzymes, other proteins and the like) and/or conditions which can decompose or deactivate the active ingredient. | 08-25-2011 |
20120015995 | BENDAMUSTINE ANIONIC-CATIOINIC CYCLOPOLYSACCHARIDE COMPOSITIONS - The present invention is directed to pharmaceutical compositions including: (a) bendamustine, (b) a first charged cyclopolysaccharide, and (c) a stabilizing agent which is a second charged cyclopolysaccharide having a charge opposite to that of the first charged cyclopolysaccharide. The composition provides unexpectedly desirable stability in reactive environments such as plasma, coupled with unexpectedly desirable anticancer activity. The compositions are suitable for injection or infusion into patients in need for treatment with bendamustine. | 01-19-2012 |
