Sea sponge drug could boost advanced breast cancer survival by 5 extra months

03.11.2014

THE cancer drug eribulin, originally developed from sea sponges, could give women with advanced triple negative breast cancer an average of five extra months of life, according to research presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool today (Monday).

Researchers led by Professor Chris Twelves, based at the University of Leeds and Leeds Teaching Hospitals NHS Trust, looked at two major clinical trials of more than 1,800 women with breast cancer that had started to spread to other parts of the body. The phase III trials – the final stage of testing before deciding whether a drug can be prescribed to patients – compared the survival of women treated with eribulin* to those given standard treatment.

The two studies showed an overall improvement in survival of more than two months for women treated with eribulin**. The most significant improvement was seen in women with the advanced triple negative form of breast cancer, where there are limited treatment options; these women's survival improved by nearly five months. There was also a survival boost of more than two months for women with the HER2 negative form of breast cancer***.

Cancer spreading to other organs – called metastasis – is responsible for around 90 per cent of all cancer deaths. And, when patients with breast cancer are diagnosed after the disease has started to spread, 10-year survival is around one in 10, compared to nearly nine in 10 for those diagnosed at the earliest stage.

Study author, Professor Chris Twelves, said: "Our results show a substantial improvement in survival for women with metastatic triple negative breast cancer, and a more modest, but significant, benefit for those with HER2 negative breast cancers.

"Eribulin has previously been offered to women who've already been through several lines of chemotherapy. But the European Union has recently approved eribulin for patients who have received less treatment for their breast cancer, which means we hope to give more patients another treatment option in the not-too-distant future.

"Despite advances in the diagnosis and treatment of women with breast cancer, more than 11,600 women still die from invasive breast cancer each year in the UK. New and better treatments are needed for people fighting the disease."

Eribulin works by stopping the cancer cells from separating into two new cells. It is a type of drug called a microtubule inhibitor. Eribulin was originally developed from a sea sponge called Halichondria okadai but is now made in the laboratory.

Martin Ledwick, head information nurse at Cancer Research UK, said: "These results are encouraging and may offer valuable extra time to patients whose cancers have stopped responding to conventional treatments and have few options left. Advanced breast cancer can be very difficult to treat so these results take us a small, important step in the right direction.

"Although eribulin isn't a cure, it's an extra treatment option for patients with advanced breast cancer, which can be priceless to them and their families."

*Eribulin (also called eribulin mesylate or Halaven) is a chemotherapy drug used to treat advanced breast cancer. It is usually given to people who have already had at least two other courses of chemotherapy. Eribulin works by stopping (inhibiting) the cancer cells from separating into two new cells. It is a type of drug called a microtubule inhibitor.

** Overall survival for women treated with eribulin was 15.2 months, compared to 12.8 months for women given standard therapies. Women with HER+ breast cancer saw no statistically significant improvement.

*** HER2 stands for human epidermal growth factor receptor. It is a protein found in small amounts on some normal cells, including breast cells, stomach cells and bladder cells. It is one of the proteins involved in cell growth. Some cancers have cells with large amounts of this protein and they are called HER2 positive. These cancers can be treated with drugs that target the HER2 protein. If a cancer does not have large amounts of the HER2 protein it is called HER2 negative.

Triple negative breast cancers are cancers that don't have receptors for oestrogen, progesterone or Her2. Only around 15 out of every 100 breast cancers (15%) are triple negative.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
