Protein-bound paclitaxel

Protein-bound paclitaxel, also known as nanoparticle albumin–bound paclitaxel or nab-paclitaxel, is an injectable formulation of paclitaxel used to treat breast cancer, lung cancer and pancreatic cancer, among others. Paclitaxel kills cancer cells by preventing the normal breakdown of microtubules during cell division.[1][2][3] In this formulation, paclitaxel is bonded to albumin as a delivery vehicle.[4] It is manufactured and sold in the United States by Celgene under the trade name Abraxane where it is designated as an orphan drug as first-line treatment, in combination with gemcitabine, for the orphan disease "metastatic adenocarcinoma of the pancreas".[5]

This treatment was approved in the United States in 2005,[6] and the European Union in 2008, for breast cancer cases where cancer did not respond to other chemotherapy or has relapsed.[7][8] In 2012, the FDA widened the approved uses to include treatment for NSCLC.[2][9] In 2013, the FDA approved protein-bound paclitaxel for use in treating advanced pancreatic cancer as a less toxic (although less effective) alternative to FOLFIRINOX.[3]

Society and culture

Abraxane is registered on the Australian Register of Therapeutic Goods for the treatment of metastatic carcinoma of the breast after failure of anthracycline therapy.[10] Abraxane is also included on the Schedule of the Australian Pharmaceutical Benefits Scheme although[11] the manufacturer was unable to convince the independent Pharmaceutical Benefits Advisory Committee that the drug warranted a higher price than existing comparator drugs. [12] Protein-bound paclitaxel was developed by VivoRx which became Abraxis BioScience as the first in its class of drugs to use the nanoparticle albumin bound (nab) technology platform.[13]

In 2010, Abraxis was acquired by Celgene, which now markets Abraxane.[14] Total revenue from the sales of Abraxane for 2009 were $314.5 million.[15] In 2013, Abraxane was FDA approved for the treatment of pancreatic cancer.[16] In 2014, Abraxane's sales were $848 million, 31 percent year-over-year increase.[17]

The British National Institute for Health and Care Excellence (NICE) announced in 2015, that it would not support the routine use of protein-bound paclitaxel in advanced pancreatic cancer on the NHS.[18]
