New PD-L1 Inhibitor Could Make Mesothelioma Immunotherapy Safer

PD-L1 Inhibitor

A new PD-L1 inhibitor may be on the horizon for people with malignant mesothelioma. A Phase I trial suggests it may be safer than some previous immunotherapy drugs.  PD-L1 is a protein that helps mesothelioma cancer cells hide from the immune system. Several of the most promising immunotherapy drugs for mesothelioma block PD-L1. But the new PD-L1 inhibitor is different. CX-072 (pacmilimab) has the ability to specifically target the tumor. This could reduce the risk for dangerous side effects since normal cells are less likely to be affected.  San Francisco-based CytomX Therapeutics developed CX-072 and a team of international researchers has been studying it. This week, they released the findings of their Phase I trial. The trial included patients with … Continue reading New PD-L1 Inhibitor Could Make Mesothelioma Immunotherapy Safer »

Study May Lead to Safer Immunotherapy for Mesothelioma

immunotherapy for mesothelioma

New research conducted in Europe and at Harvard University may open the door to safer immunotherapy for mesothelioma patients.  Immunotherapy is one of the most promising approaches to fight malignant mesothelioma. But the potential side effects can be devastating.  Now, new data suggests there are ways to reduce the complications of immunotherapy for mesothelioma. The key is to target some of the white blood cells that trigger inflammation. Inflammation is the driver behind most of the serious side effects of immunotherapy.  Why Harness the Immune System? No one ever expects to contract mesothelioma. It is an extremely rare cancer. Most people who get it have spent time living or working around asbestos. Even among asbestos-exposed people, mesothelioma is rare. Scientists … Continue reading Study May Lead to Safer Immunotherapy for Mesothelioma »

Early Data Show Promise for Galinpepimut-S and Opdivo in Mesothelioma Patients

galinpepimut-s and opdivo

A combination of the immunotherapy drugs galinpepimut-S and Opdivo may give mesothelioma patients a few extra months, according to newly-released data.  The clinical data is part of an ongoing study of galinpepimut-S and Opdivo. SELLAS Life Sciences Group, the makers of galinpepimut-S, released the latest findings this week.  Although the early data is based on just four mesothelioma cases, it appears to be promising. All of the study subjects had either relapsed after chemotherapy or failed to respond at all.  These patients had a median overall survival of 35.4 weeks on the combination of galinpepimut-S and Opdivo. Typical overall survival in relapsed patients with standard care is just 7 months.  Immunotherapy with Galinpepimut-S and Opdivo Galinpepimut-S and Opdivo are both … Continue reading Early Data Show Promise for Galinpepimut-S and Opdivo in Mesothelioma Patients »

Immunotherapy Treatment ONCOS-102: News Keeps Getting Better

immunotherapy treatment

The news just keeps getting better for the virus-based immunotherapy treatment ONCOS-102.  Norweigian drug maker Targovax recently released the final survival data from a two-year study of ONCOS-102 in people with malignant pleural mesothelioma.  Eighteen months into the study, it looked like some of the patients on the immunotherapy treatment would live longer than two years. Now that the ONCOS-102 study has passed the two year mark, researchers say median survival may be even longer.  Average survival is a year or less on standard mesothelioma therapies. This makes the news about ONCOS-102 especially exciting.  Standard of Care Versus Immunotherapy Treatment Malignant mesothelioma is an aggressive malignancy with a poor prognosis. Even patients in overall good health face a grim outlook. … Continue reading Immunotherapy Treatment ONCOS-102: News Keeps Getting Better »

Effectiveness of Keytruda: Dutch Study Offers Clues for Prediction

effectiveness of Keytruda

A new Dutch study offers some clues that might help doctors predict the effectiveness of Keytruda (pembrolizumab) in individual mesothelioma patients.  Keytruda is the brand name for pembrolizumab. It is an immunotherapy drug called an immune checkpoint inhibitor. It helps unmask mesothelioma cells so that the immune system can find and fight them.  But the effectiveness of Keytruda is not consistent. Some patients respond well while others do not respond at all. The new study looked at how different people metabolize the drug. Understanding this could help doctors determine the best dose for each mesothelioma patient.  Pembrolizumab and its Link to Mesothelioma Survival Malignant pleural mesothelioma is a deadly form of lung cancer. Asbestos exposure is the main cause of … Continue reading Effectiveness of Keytruda: Dutch Study Offers Clues for Prediction »

Breath Test Could Predict Mesothelioma Immunotherapy Response

breath test

New research shows a breath test called an eNose might help doctors determine which mesothelioma patients are most likely to respond to immunotherapy.  Immunotherapy is one of the most promising new approaches to malignant mesothelioma. But not every patient responds.  A new Dutch study suggests that biomarkers in a patient’s exhaled breath may be indicators of immunotherapy response. The eNose breath test can identify those biomarkers quickly and easily. The technology might make it easier to decide on the best mesothelioma treatment.  Immunotherapy for Malignant Mesothelioma Pleural mesothelioma is a rare but deadly cancer of the lung lining. Until last year, chemotherapy with Alimta (pemetrexed) was the only FDA-approved systemic treatment.  In 2020, the FDA approved a combination of immunotherapy … Continue reading Breath Test Could Predict Mesothelioma Immunotherapy Response »

Inflammation Protein May Impact Drug Therapies for Mesothelioma

drug therapies

A protein involved in the inflammatory process could impact how patients respond to drug therapies for mesothelioma. The news comes from researchers at Fox Chase Cancer Center in Philadelphia.  The team led by Joseph Testa, PhD, recently released a study of a protein called RIPK3 and its role in malignant mesothelioma.  Their research showed that people with little or no expression of RIPK3 were less sensitive to drug therapies for mesothelioma. Turning that gene back on might make tumor cells more responsive. The finding could lead to new, more powerful ways to treat this aggressive cancer.  RIPK3, Mesothelioma, and Inflammation Mesothelioma is a rare but fast-growing form of cancer that comes from asbestos exposure. Tumors grow on the tissue that … Continue reading Inflammation Protein May Impact Drug Therapies for Mesothelioma »

Latest Keytruda Study Shows Limited Results for Most Mesothelioma Patients

latest keytruda study

Results of the latest Keytruda study show the drug works well for a select few mesothelioma patients, but not well at all for most others. Keytruda is the brand name for pembrolizumab. It is a type of immunotherapy drug. Early studies suggested that Keytuda might offer real hope for people with the aggressive cancer, malignant pleural mesothelioma.  But the latest Keytruda study shows most patients do not have lasting results with this treatment. That is especially true for patients whose cells do not express high levels of the protein PD-1. How the Latest Keytruda Study Worked Keytruda is an immunotherapy drug. It works by activating the immune system. Mesothelioma cells can use a protein called PD-1 to protect themselves from … Continue reading Latest Keytruda Study Shows Limited Results for Most Mesothelioma Patients »

Different Mesothelioma Subtypes: Gene Study Could Lead to Targeted Treatments

different mesothelioma subtypes

A group of European pathologists say the different mesothelioma subtypes have significant differences in their pattern of gene expression. Exploiting these differences could help scientists craft more effective mesothelioma treatments.  Asbestos exposure is the primary cause of mesothelioma. But doctors know that genetics play a role, too. Newly-approved immunotherapy drugs target proteins expressed by specific genes. But these drugs work much better in some mesothelioma patients than they do in others.  The new study suggests that differences in the genetic profiles of different mesothelioma subtypes could help explain why.  Immunotherapy Drugs for Mesothelioma Immunotherapy is an up-and-coming treatment approach for mesothelioma and other cancers. It harnesses the power of the person’s immune system to fight cancer.  In people with mesothelioma, … Continue reading Different Mesothelioma Subtypes: Gene Study Could Lead to Targeted Treatments »
