The combination, which importantly does not include a platinum drug, challenges the current standard of treatment for women whose cancer recurs at least 6 months after first-line treatment, said Associate Prof. Bradley J. Monk from the University of California Irvine Medical Center.
“This trial, which included almost two-thirds such women, challenges this traditional paradigm and suggests that a non-platinum doublet is also effective in this setting,” he said. “Trabectedin represents a ‘new chemical entity’ in North America and if approved by the FDA, would be an important new option for women with recurrent ovarian cancer.”
Trabectedin, a synthetic version of a compound first isolated from sea-squirts, has been granted marketing approval in Europe for the treatment of patients with advanced soft tissue sarcoma.
In the latest trial, an international group of researchers studied the combination in 672 women whose ovarian cancer had progressed after first-line therapy. Half the women received pegylated liposomal doxorubicin 30 mg/m2 over 60 min plus trabectedin 1.1mg/m2 over 3 hours every 3 weeks, the remainder received pegylated liposomal doxorubicin 50 mg/m2 alone every 4 weeks.
The median length of progression-free survival for women on the combination therapy was 7.3 months, the researchers found, compared to 5.8 months for those treated with the single drug. For those who had relapsed more than six months after the first-line therapy, the median progression-free survival time was 9.2 months for the combination treatment, compared to 7.5 months for patients in the other arm.
“This drug appears active in all sub-groups included in the trial, but like all agents is most active among those with longer time intervals since their front-line chemotherapy treatment,” Prof. Monk said.
“Positive trials in recurrent ovarian cancer are rare and have almost always led to newly approved therapeutic regimens,” he said. “This combination will undoubtedly be carefully evaluated by the FDA and if approved would give women with ovarian cancer another much-needed option.”

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
Fraunhofer IZM is joining the EUROPRACTICE IC Service platform. Together, the partners are making fan-out wafer level packaging (FOWLP) for electronic devices available and affordable even in small batches – and thus of interest to research institutes, universities, and SMEs. Costs can be significantly reduced by up to ten customers implementing individual fan-out wafer level packaging for their ICs or other components on a multi-project wafer. The target group includes any organization that does not produce in large quantities, but requires prototypes.
Research always means trying things out and daring to do new things. Research institutes, universities, and SMEs do not produce in large batches, but rather...
