Oxaliplatin, sold under the brand name Eloxatin among others, is a

injection into a vein.[5]

Common side effects include

allergic reactions.[6][5] Use in pregnancy is known to harm the baby.[5] Oxaliplatin is in the platinum-based antineoplastic family of medications.[7] It is believed to work by blocking the duplication of DNA.[5]

Oxaliplatin was patented in 1976 in Japan and approved for medical use in 1996 in Europe.[8] It is on the 2023 World Health Organization's List of Essential Medicines.[9]

Medical uses

Oxaliplatin is used for treatment of

Advanced colorectal cancer

Oxaliplatin by itself has modest activity against advanced colorectal cancer.

5-fluorouracil and folinic acid administered according to the de Gramont regimen, a FOLFOX4 regime produced no significant increase in overall survival, but did produce an improvement in progression-free survival, the primary end-point of the phase III randomized trial.[15]

Adverse effects

Side-effects of oxaliplatin treatment can potentially include:

In addition, some patients may experience an allergic reaction to platinum-containing drugs. This is more common in women.[19]

Oxaliplatin has less ototoxicity and nephrotoxicity than cisplatin and carboplatin.[16]

Structure and mechanism

The compound features a

trans-1,2-diaminocyclohexane in place of the two monodentate ammine ligands. It also features a bidentate oxalate group.[7] The three-dimensional structure of the molecule has been elucidated by X-ray crystallography, although the presence of pseudosymmetry in the crystal structure has caused confusion in its interpretation.[22]

According to

cytotoxic effects. Like other platinum compounds, its cytotoxicity is thought to result from inhibition of DNA synthesis in cells. In particular, oxaliplatin forms both inter- and intra-strand cross links in DNA,[23]
which prevent DNA replication and transcription, causing cell death.

History

Oxaliplatin was first synthesized in 1978 at

U.S. Food and Drug Administration in 2002.[26] Generic oxaliplatin was first approved in the United States in August 2009.[27] Patent disputes caused generic production to stop in 2010, but it restarted in 2012.[28][29]

Patent information

Eloxatin was covered by patent numbers 5338874 (expired 7 April 2013), 5420319 (expired 8 August 2016), 5716988 (expired 7 August 2015) and 5290961 (expired 12 January 2013) (see Electronic Orange Book patent info for Eloxatin).[30] Exclusivity code I-441, which expired on 4 November 2007, is for use combination with infusional 5-FU/LV for adjuvant treatment stage III colon cancer patients who have undergone complete resection primary tumor-based on improvement in disease free survival with no demonstrated benefit overall survival after 4 years. Exclusivity code NCE, New Chemical Entity, expired on 9 August 2007.[30]
