Chemotherapy is likely the most prevalent treatment utilized by patients of malignant pleural mesothelioma. While several different chemotherapy drugs have been utilized to varying degrees of effectiveness for the management of malignant pleural mesothelioma, only one has been approved by the Food and Drug Administration as a prescribed therapy for the treatment of malignant pleural mesothelioma. A combination of Alimta (Pemetrexed) and Cisplatin is currently the only cocktail prescribed en masse for the general treatment of pleural mesothelioma. However, several other clinical trials are currently active attempting to determine the effectiveness of other drugs including Gemcitabine, Navelbine, and Onconase.
