Relapsed Mesothelioma Patients Live Longer on Opdivo in Phase 3 Trial

relapsed mesothelioma patients

A multi-center British study suggests that the cancer drug Opdivo (nivolumab) may be a solid second-line treatment option for relapsed mesothelioma patients.  The Phase-3 trial involved mesothelioma patients from 24 UK hospitals. All had an ECOG score of 0 or 1, meaning they were in reasonably good health overall.  All of the patients had first-line treatment with platinum-based chemotherapy. Then their cancer came back. There is no approved treatment for relapsed mesothelioma patients. So these patients enrolled in the nivolumab trial.  Although Opdivo is not a cure for mesothelioma, the results of the news trial show it could extend survival for the right patients.  How Does Opdivo Work? Nivolumab is sold under the brand name Opdivo. It is an immunotherapy … Continue reading Relapsed Mesothelioma Patients Live Longer on Opdivo in Phase 3 Trial »

Statin Drugs Support Immunotherapy for Mesothelioma, New Study Finds

statin drug

There’s more evidence that statin drugs may improve the effectiveness of mesothelioma immunotherapy.  The new study, led by Korean biochemists, is not the first to show that these anti-cholesterol medications may help mesothelioma patients. But this one goes a step further to explain why they help.  Researchers focused on the impact of statin drugs on PD-1 expression. PD-1 is a protein that protects mesothelioma cells against immune system attack.  The findings suggest that, by lowering PD-1 levels, anti-cholesterol drugs may play a greater role in the future of mesothelioma treatment.  PD-1 and Mesothelioma Immunotherapy PD-1 is an immune checkpoint protein that occurs on the surface of cells. Normally, it helps keep the immune system from attacking healthy tissues. But mesothelioma … Continue reading Statin Drugs Support Immunotherapy for Mesothelioma, New Study Finds »

Higher PD-L1 Protein May Predict Shorter Mesothelioma Survival

PD-L1 protein

Mesothelioma patients with higher levels of the PD-L1 protein in their tumor cells have worse overall survival compared to those with lower levels. But that may not be true for patients who have immunotherapy. That news comes from a new European study of more than 200 patients. PD-L1 and its partner protein PD-1 (found in immune system cells) are popular targets for new immunotherapy drugs. But the new study aimed to find out if they impact mesothelioma survival independently of immunotherapy. The team concluded the PD-L1 protein may shorten lifespan. PD-1 does not seem to have the same effect.  Pleural Mesothelioma and the PD-L1 Protein Pleural mesothelioma is an intractable cancer of the lung lining. It often leads to poor … Continue reading Higher PD-L1 Protein May Predict Shorter Mesothelioma Survival »

Cholesterol Drugs Extend Mesothelioma Survival in New Study

cholesterol drugs

Cholesterol drugs called statins have been shown to improve survival among mesothelioma patients taking PD-1 inhibitors.  The news comes from an international study from cancer researchers in Italy and the Netherlands.  More than 250 patients with pleural mesothelioma or non-small cell lung cancer were evaluated for the study. Researchers found that those who took cholesterol drugs while also receiving PD-1 blockers like Keytruda lived longer and had slower disease progression.  Mesothelioma Patients and Statins The body needs some cholesterol to build healthy cells. But many adults have too much cholesterol in their blood. This can lead to fatty deposits in the arteries that raise the risk for heart disease and stroke.  Cholesterol drugs called statins are designed to bring cholesterol … Continue reading Cholesterol Drugs Extend Mesothelioma Survival in New Study »

CAR T-Cell Therapy for Mesothelioma in New Phase I Trial

CAR T-Cell Therapy for Mesothelioma

Researchers at Memorial Sloan Kettering in New York are about to try a new kind of CAR T-cell therapy for mesothelioma in human patients.  This is the first Phase I trial of the new CAR T-cell approach. The therapy involves removing some of a patient’s T-cells, modifying them, and giving them back to fight cancer.  The new CAR T-cell therapy for mesothelioma involves cells that have been modified in new ways. They still seek out cancer cells. But these CAR T-cells are made to last longer and to undermine a primary mesothelioma cell defense mechanism. The FDA approved the study in September. Memorial Sloan Kettering is recruiting mesothelioma patients for it now.  T-Cells That Target Mesothelioma Cells CART T-cell therapy … Continue reading CAR T-Cell Therapy for Mesothelioma in New Phase I Trial »

Shorter Mesothelioma Survival Again Linked to Higher PD-L1 Levels

shorter mesothelioma linked to protein

Patients with the rarest mesothelioma subtypes tend to experience shorter mesothelioma survival. Now, new mesothelioma research suggests that may have something to do with a protein called PD-L1. French researchers studied the PD-L1 levels in the tumors of 214 mesothelioma patients. They compared the levels with each patient’s subtype and their treatment outcome.  The results may help explain cases of shorter mesothelioma survival, especially among patients with sarcomatoid or biphasic mesothelioma subtypes.  PD-L1 Levels and Shorter Mesothelioma Survival Programmed death ligand 1 (PD-L1) is one of the proteins that helps mesothelioma cells and other cancers “hide” from the immune system.  Normally, the immune system finds and destroys renegade cells. But if a patient’s mesothelioma tumor expresses higher amount of PD-L1, … Continue reading Shorter Mesothelioma Survival Again Linked to Higher PD-L1 Levels »
