DHA-paclitaxel (or Taxoprexin) is an investigational drug (from Protarga Inc) made by linking paclitaxel to docosahexaenoic acid (DHA), a fatty acid that is easily taken up by tumor cells; the DHA-paclitaxel “appears not to be cytotoxic until the bond with DHA is cleaved within the cell.”{{Cite journal | author = Whelan, Jo | journal = Drug Discovery Today | volume = 7 | issue =2 | year = 2002 | pages = 90–92 | doi = 10.1016/S1359-6446(01)02149-3 | pmid = 11790612 | title = Targeted taxane therapy for cancer}} The advantage of DHA-paclitaxel over paclitaxel is DHA-paclitaxel's ability to carry much higher concentrations of paclitaxel to the cells, which are maintained for longer periods in the tumor cells, thus increasing their action. With increased activity, DHA-paclitaxel, also known as Taxoprexin, may have a more successful response in cancer patients than Taxol, and it may be able to treat more types of cancer than Taxol has been able to treat.

Clinical trials

In 2007, a phase II clinical trial reported "modest activity in patients with oesophago-gastric cancer".{{cite journal | pmid = 17440725 | year = 2008 | last1 = Jones | first1 = RJ | last2 = Hawkins | first2 = RE | last3 = Eatock | first3 = MM | last4 = Ferry | first4 = DR | last5 = Eskens | first5 = FA | last6 = Wilke | first6 = H | last7 = Evans | first7 = TR | title = A phase II open-label study of DHA-paclitaxel (Taxoprexin) by 2-h intravenous infusion in previously untreated patients with locally advanced or metastatic gastric or oesophageal adenocarcinoma | volume = 61 | issue = 3 | pages = 435–41 | doi = 10.1007/s00280-007-0486-8 | journal = Cancer Chemotherapy and Pharmacology}}
