Sorafenib, sold under the brand name Nexavar, is a medication used to treat renal cell carcinoma, hepatocellular carcinoma, and certain types of thyroid cancer.[2][1] It is taken by mouth.[1]

Common side effects include diarrhea, rash, hair loss, infection, rash, and tiredness.[1] Other side effects may include a heart attack, gastrointestinal perforation, liver problems, bleeding, and high blood pressure.[1] Use in pregnancy or breastfeeding may harm the baby.[4] It is a protein kinase inhibitor.[1]

Sorafenib was approved for medical use in the United States in 2005 and Europe in 2006.[2][1] In the United Kingdom 4 weeks of treatment costs the NHS about £3,600 as of 2021.[3] This amount in the United States costs about 20,200 USD.[5]

Medical uses

Sorafenib is indicated as a treatment for advanced renal cell carcinoma (RCC), unresectable hepatocellular carcinomas (HCC) and thyroid cancer.[6][7][8][9]

Kidney cancer

Clinical trial results, published January 2007, showed that, compared with placebo, treatment with sorafenib prolongs progression-free survival in patients with advanced clear cell renal cell carcinoma in whom previous therapy has failed. The median progression-free survival was 5.5 months in the sorafenib group and 2.8 months in the placebo group (hazard ratio for disease progression in the sorafenib group, 0.44; 95% confidence interval [CI], 0.35 to 0.55; P<0.01).[10]

In Australia this is one of two TGA-labelled indications for sorafenib, although it is not listed on the Pharmaceutical Benefits Scheme for this indication.[9][11]

Liver cancer

At ASCO 2007, results from the SHARP trial[12] were presented, which showed efficacy of sorafenib in hepatocellular carcinoma. The primary endpoint was median overall survival, which showed a 44% improvement in patients who received sorafenib compared to placebo (hazard ratio 0.69; 95% CI, 0.55 to 0.87; p=0.0001). Both median survival and time to progression showed 3-month improvements; however, there was no significant difference in median time to symptomatic progression (p=0.77). There was no difference in quality of life measures, possibly attributable to toxicity of sorafenib or symptoms related to underlying progression of liver disease. Of note, this trial only included patients with Child-Pugh Class A (i.e. mildest) cirrhosis.[12] Because of this trial Sorafenib obtained FDA approval for the treatment of advanced hepatocellular carcinoma in November 2007.[13]

In a randomized, double-blind, phase II trial combining sorafenib with doxorubicin, the median time to progression was not significantly delayed compared with doxorubicin alone in patients with advanced hepatocellular carcinoma. Median durations of overall survival and progression-free survival were significantly longer in patients receiving sorafenib plus doxorubicin than in those receiving doxorubicin alone.[13]

A prospective single-centre phase II study which included the patients with unresectable hepatocellular carcinoma (HCC)concluding that the combination of sorafenib and DEB-TACE in patients with unresectable HCC is well tolerated and safe, with most toxicities related to sorafenib.[14]

In Australia this is the only indication for which sorafenib is listed on the PBS and hence the only Government-subsidised indication for sorafenib.[11] Along with renal cell carcinoma, hepatocellular carcinoma is one of the TGA-labelled indications for sorafenib.[9]

Thyroid cancer

On November 22, 2013, sorafenib was approved by the FDA for the treatment of locally recurrent or metastatic, progressive differentiated thyroid carcinoma (DTC) refractory to radioactive iodine treatment.[15]

The Phase 3 DECISION trial showed significant improvement in progression-free survival but not in overall survival. However, as is known, the side effects were very frequent, specially hand and foot skin reaction.[16]

Dosage

It is generally taken at a dose of 400 mg twice per day.[3]

Side effects

Sorafenib- induced hand - foot syndrome with the typical focal hyperkeratosis over the pressure points

By frequency
Very common (>10% frequency)

Common (1-10% frequency)

  • Transient increase in transaminase

Uncommon (0.1-1% frequency)

Rare (0.01-0.1% frequency)

Mechanism of action

Mechanism of action of sorafenib.[19]

Sorafenib is a protein kinase inhibitor with activity against many protein kinases, including VEGFR, PDGFR and RAF kinases.[20][13]

Of the RAF kinases, Sorafenib is more selective for c-Raf than B-RAF.[21]

Sorafenib treatment induces autophagy,[22] which may suppress tumor growth. Based on its 1,3-disubstituted urea structure, Sorafenib is also a potent soluble epoxide hydrolase inhibitor and this activity likely reduces the severity of its adverse effects.[23]

History

Renal cancer

Sorafenib was approved by the U.S. Food and Drug Administration (FDA) in December 2005,[24] and received European Commission marketing authorization in July 2006,[25] both for use in the treatment of advanced renal cancer.

Liver cancer

The European Commission granted marketing authorization to the drug for the treatment of patients with hepatocellular carcinoma(HCC), the most common form of liver cancer, in October 2007,[26] and FDA approval for this indication followed in November 2007.[27]

In November 2009, the UK's National Institute of Clinical Excellence declined to approve the drug for use within the NHS in England, Wales and Northern Ireland, stating that its effectiveness (increasing survival in primary liver cancer by 6 months) did not justify its high price, at up to £3000 per patient per month.[28] In Scotland the drug had already been refused authorization by the Scottish Medicines Consortium for use within NHS Scotland, for the same reason.[28]

In March 2012, the Indian Patent Office granted a domestic company, Natco Pharma, a license to manufacture generic Sorafenib, bringing its price down by 97%. Bayer sells a month's supply, 120 tablets, of Nexavar for280,000 (US$3,400). Natco Pharma will sell 120 tablets for 8,800 (US$110), while still paying a 6% royalty to Bayer. The royalty was later raised to 7% on appeal by Bayer.[29][30][31] Under the Patents Act, 1970 and the World Trade Organisation TRIPS Agreement, the government can issue a compulsory license when a drug is not available at an affordable price.[32]

Research

Lung

In some kinds of lung cancer (with squamous-cell histology) sorafenib administered in addition to paclitaxel and carboplatin may be detrimental to patients.[33]

Ovarian cancer

Sorafenib has been studied as maintenance therapy after ovarian cancer treatment and in combination with chemotherapy for recurrent ovarian cancer but did not show results that led to approval of the drug for these indications.[34]

Brain

There is a phase I/II study at the Mayo Clinic[35] of sorafenib and CCI-779 (temsirolimus) for recurrent glioblastoma.

Desmoid tumor

A study performed in 2011 showed that sorafenib is active against aggressive fibromatosis. This study is being used as justification for using Sorafenib as an initial course of treatment in some patients with aggressive fibromatosis.[36]

A phase 3 clinical trial is under way testing the effectiveness of Sorafenib to treat desmoid tumors (also known as aggressive fibromatosis), after positive results in the first two trial stages. Dosage is typically half of that applied for malignant cancers (400 mg vs 800 mg). NCI are sponsoring this trial.[37][38]

Nexavar controversy

In January 2014, Bayer's CEO Marijn Dekkers allegedly stated that Nexavar was developed for "Western Patients Who Can Afford it, not for Indians". However, Dekkers actually never said this. In fact, his words were misquoted and the context was omitted. A kidney cancer patient would pay $96,000 (£58,000) for a year's course of the Bayer-made drug, whereas the cost of the Indian version of the generic drug would be around $2,800 (£1,700).>[39]
