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.”

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
