Chicago and Madrid, June 1st 2015: PharmaMar today announced data from a Phase 2 study in patients with sarcomatoid/biphasic malignant pleural mesothelioma showing that 41.2% (95% CI: 18.4-67.1) of patients treated with the anticancer drug trabectedin in second line were alive and free of progression at 12 weeks. The median progression-free survival (PFS) in these 17 evaluated patients was 8.3 weeks. There were 5 patients who continue receiving trabectedin beyond 12 weeks.
"Mesothelioma patients usually do not respond to second-line treatments so the preliminary data we observed here is encouraging. This study also adds to the scarce evidence-based science in this disease, as the use of trabectedin is based on its direct effect on tumor-associated macrophages and its efficacy in different tumors, including soft tissue sarcomas." Said Diego Luigi Cortinovis, MD, Medical Oncologist San Gerardo Hospital, Monza, Italy. "Given the aggressiveness of this disease and the poor response of this mesothelioma population, the indication that this treatment might be active in these patients is a major advance and warrants further investigation in a larger population."
The lead author Dr. Diego Luigo Cortinovis, San Gerardo Hospital, Monza, Italy will present the full data today at the 51st Annual Meeting of the American Society of Clinical Oncology (ASCO) (Abstract#7561, Monday, June 1 from 8:00 AM to 11:30 AM at S Hall A Poster Board 309).

About mesothelioma
Mesothelioma is a type of cancer mainly caused by asbestos exposure and patients usually show symptoms after a long period of time. In malignant disease, tumor cells normally form in the thin tissue layer (called pleura) that covers the lung, chest wall, or abdomen. The most common type of malignant disease is epithelial, which forms in the cells that line organs, and there is also a second type called sarcomatoid. The former type is less aggressive and patients have a better prognosis compared to other types . The number of new cases of malignant mesothelioma worldwide has been rising in the last 70 years and the numbers highly vary within and between countries. In the US, there are about 3,000 new cases being diagnosed each year mostly in elderly men , but in Australia and some European countriesthe incidence of mesothelioma may still be rising. In Italy 2004, there were 2.4 new cases per 100.000 people in 2004 . Malignant mesothelioma is characterized by increased chronic inflammation in the tumor microenvironment and the role of tumor associated macrophage (TAM) . The prognosis of patients with mesothelioma is poor with a 5-year survival rate of about 10 percent and a median survival time for those diagnosed with advance disease stage IV of about 12 months .
