Association Between Proton Pump Inhibitors and Hematologic Toxicity of Pemetrexed (IPPEM)

Pemetrexed is a multi-folate inhibitor approved in the treatment of non-small cell lung cancer (NSCLC) and pleural mesothelioma. Its toxicity profile is mainly hematologic (anemia, neutropenia and thrombopenia) and can be limiting when > grade 2 according to NCI-CTCAE criteria. First clinical trials highlighted hematologic toxicity, especially anemia, which was reduced by decreasing pemetrexed dosage from 600 to 500 mg/m² Q3W and by adding systematic vitamin supplementation (B9/B12). Despite this, incidence of hematological toxicity remains frequent with anemia occurring in more than 20% of patients treated by pemetrexed in combination. The investigators aim to investigate the potential association between PPIs and pemetrexed combination and the incidence of hematological toxicity in a multicenter and prospective study.

EPA Proposes New Rules For Asbestos; Anti-Asbestos Advocates Concerned

In June 2016, former President Obama signed the Frank R. Lautenberg Chemical Safety for the 21st Century Act as an amendment to the Toxic Substances Control Act (TSCA), and since then, the Environmental Protection Agency (EPA) has been moving forward in naming asbestos – as well as nine other chemicals – as toxic substances that…

Updated Modified RECIST to Better Evaluate Treatment Response in Mesothelioma

The Response Evaluation Criteria in Solid Tumors (RECIST) was established nearly two decades ago by the European Organization for Research and Treatment of Cancer and the National Cancer Institute of the United States. The purpose of these published rules was to universally define when cancerous tumors stabilize, progress, or just respond to any given treatment.…

Olaparib in People With Malignant Mesothelioma

Purpose: The drug olaparib may stop cancer cells from fixing damage to their DNA. It has been approved to treat certain cancers in people that were born with a mutation in the BRCA gene. It has not been approved for treating mesothelioma. But some people with mesothelioma have mutations in a gene, BAP1 related to BRCA. Researchers want to see if olaparib can work in patients with mutations in this gene. They also want to see if works on mutations in other genes or patients without any mutations. They want to see if olaparib causes mesothelioma tumors to shrink.
