A new worldwide clinical trial for mesothelioma is now open for enrollment
The “handshake” between the tumor and T cell prevents a T cell immune attack against mesothelioma. Disrupting the “handshake” holds the key to an immune response against this cancer. This Phase 3 immunotherapy clinical trial for mesothelioma tests a drug made to do exactly that and is now available to patients in the United States and across the world.
A new phase 3 clinical trial testing the efficacy of dual checkpoint inhibitor immunotherapy in combination with chemotherapy is now available to patients in the United States as well as around the world. The official name for the study is MEDI5752 in Combination With Carboplatin Plus Pemetrexed in Unresectable Pleural Mesothelioma and the shortened name is eVOLVE-Meso.
This AstraZeneca study tests a single immunotherapy agent called volrustomig in combination with standard chemotherapy against either standard of care chemotherapy alone or immunotherapy alone. The study builds on the recent FDA-approval of immunotherapy for mesothelioma which saw two agents, nivolumab (Opdivo) and ipilimumab (Yervoy), activate the immune system against cancer cells by binding to two receptors located on the T cell: the PD-1 and the CTLA-4. Single agent volrustomig targets the same two proteins, but the study also adds standard chemotherapy to its protocol.
How to inquire about enrollment?
The clinical trial is widely available at centers across the United States. A patient should contact their treating physician to discuss enrollment. Locations where the Evolve-Meso clinical trial is available are listed here: https://clinicaltrials.gov/study/NCT06097728#contacts-and-locations.
How does immunotherapy work to kill mesothelioma cells?
To understand how immunotherapy treatment works, we must first understand why the immune system tends to stay inactive against mesothelioma cells. Both the T cell and other cells, including tumors, express proteins. When certain proteins on the T cell bind to their counterparts on a healthy cell, this communicates to the T cell to not attack the healthy cell. This is an important preservation mechanism that prevents autoimmune reactions. So when the tumor’s proteins bind to the ones on the T cell, they tell the immune system not to attack which allows the cancer to proliferate. Immunotherapy medications act as a decoy binding protein that binds to either the T cell or the tumor cell, disrupting their ability to bind with one another.
In the top part of this image, the T cell and the tumor cell connect causing no immune response against the tumor. In the bottom part of the image, the immunotherapy drugs connect to the expressed proteins on either the T cell or tumor thus inhibiting the connection between the two which in turn creates an immune reaction against the tumor. This is the basis of checkpoint inhibitor immunotherapy.
Immunotherapy + Chemotherapy: what is the rationale?
A common and valid question about combining chemotherapy with immunotherapy is: are we just throwing the kitchen sink at mesothelioma to see what sticks?
The answer is no.
There are, in fact, scientific reasons that would suggest that combining these two methods would lead to better results than administering them one at a time. Reason number one can be found in the answer to the question “why does the immune system not recognize mesothelioma as a foreign entity worth attacking from the beginning?” The answer is that mesothelioma cells’ receptors mimic those on the surface of healthy cells and they use the brakes built into the immune system to their advantage. But when chemotherapy is used to kill the cancer, the by-product of those dead cancer cells is seen as a foreign body by the immune system. So, adding chemotherapy to an immunotherapy regimen is one way to maximize the anti-tumor activity of both agents.
Timeline of FDA-approvals for mesothelioma
2004: Chemotherapy (Alimta/cisplatin)
2022: Immunotherapy (nivolumab / ipilimumab)
2024: Immunotherapy + chemotherapy for advanced mesothelioma (pembrolizumab also known by the brand name Keytruda, which is an anti-PD-1 agent, plus standard chemotherapy)
What is the difference between volrustomig and other immunotherapy agents used against mesothelioma
The volrustomig study is different from the 2024 immunotherapy (Keytruda) plus chemotherapy combination approval because volrustomig singularly binds to both the PD-1 and CTLA-4 receptors. Immunotherapy drugs targeting only the PD-1 or PDL1 receptors have shown to not be as effective as those also targeting the CTLA-4 receptor.
These two proteins, also known as checkpoint inhibitors, are located on the T cell. There, they play a crucial role in signaling to the immune system whether to attack the cancer cells or not. Without immunotherapy treatment, the tumor receptors (PD-L1 and CD80) bind to the reciprocal T cell receptors, signaling to the immune system not to attack the tumor. With immunotherapy that binds to them instead, the “handshake” between the tumor and the T cell is disrupted letting the immune system to attack the tumor.
Why should a patient consider participation in this study?
Mesothelioma patients have limited options for treatment available to them while the cancer is aggressive and moves fast. This study is an opportunity to try the combination of chemotherapy plus immunotherapy to potentially reap the most benefits.
What are the risks?
As with any study and/or treatment, one risk is that the treatment won’t work. With mesothelioma, this is a significant risk because the disease is quick and aggressive. However, over time, survival for mesothelioma patients has increased at least in part due to advancements in treatment options, and this study is one such option. Being a Phase 3 clinical trial, the drugs it uses have already been extensively studied for safety, but it is important to note that undergoing any type of immunotherapy can cause unintended immune reactions some of which can be life threatening. Speaking with the treating physician about potential risks and benefits is an important part of enrolling into a clinical trial.
What other treatments are in the works for mesothelioma?
Two other significant studies have been released in the last two years, both holding promise with regards to further treatment approvals. Both studies showed an improvement in survival in the most aggressive type of mesothelioma called the sarcomatoid subtype.
One of these studies combined Alimta/cisplatin (chemotherapy) with atezolizumab (immunotherapy) and also with bevacizumab (a VEGF inhibitor agent that limits vascular development leading to the tumor).
The other study, called ATOMIC, was successful in improving survival in the sarcomatoid and biphasic mesothelioma subtypes (most aggressive) by depriving the cancer cells of arginine, which is generally widely present in the most aggressive mesotheliomas.

New episode of Meet the Mesothelioma Experts About Financial Compensation for Mesothelioma
Last week, the Mesothelioma Applied Research Foundation released a new episode of its Meet the Mesothelioma Experts: Legal Edition series discussing financial compensation issues for mesothelioma patients. Featured guest of the program was Joseph Belluck, partner with the Belluck & Fox firm, who was interviewed by the organization’s board of directors’ member, Cheryl Bruner. Mr. Belluck answered a number of questions of interest to those who have just had a mesothelioma diagnosis and their families.
Acting with Urgency
One of the take-home messages is that while a mesothelioma diagnosis requires medical urgency and treatment, so does the legal process. This is due to a number of issues, the statute of limitations being one, but not the only one. As Mr. Belluck states in this program, it is important to file a lawsuit as soon as realistically possible in order to get a place in line, even if later adjustments are necessary. An experienced law firm will know enough information about a case very quickly and will be able to proceed with expedience.
“Usually, right after contact, we file the case, we start working on the bankruptcy trust claims and also starting to work on the lawsuit, which we do in tandem. Typically, the first settlements will come in about 45 – 60 days and the whole case will be completed within 12 months,” said Mr. Belluck in the program.
Mr. Belluck adds that whether a patient chooses to hire his firm or another firm, he still encourages them to make sure to do so quickly for the reasons outlined above.

Compensation Programs for Mesothelioma Patients and their Families
There are several main compensation programs that are typically available to mesothelioma patients. They include simple programs like health insurance, private disability insurance, social security disability benefits, and workers compensation if the person is still employed. Additionally, veterans’ benefits are available for people who served in the military and have a service connection to asbestos exposure. Mesothelioma bankruptcy trusts are another avenue to pursue for compensation. There are about 40-50 individual funds that have been set up by companies that made asbestos products and went into bankruptcy. As part of their bankruptcy reorganization, they set up a fund for their product. And the last option available is to file a lawsuit individually, not a class action, against the companies that made asbestos products that the patient was exposed to.

Mesothelioma Treatment News: Delivering therapies directly into the pleural space
In a new article published in the medical journal The Lancet (Leveraging the pleural space for anticancer therapies in pleural mesothelioma by Blythe at al., 2024), authors make an argument for renewed focus toward therapies that can be delivered directly into the intrapleural space.
The benefit of such therapies is that by targeting the tumor directly, doctors are able to use higher doses of medication for increased likelihood of success while limiting toxicity to the patient.
Pleural mesothelioma is a cancer of the lining that surrounds the lung, which is called the pleura. So far, most attention has been devoted toward finding systemic treatments that work – a feat that has proven to be quite challenging. Systemic treatments are treatments such as chemotherapy or immunotherapy, which are administered through a vein, that travel throughout the entire body to kill the cancer cells wherever they may be. These treatments are currently the standard of care, but many patients’ tumors still don’t respond to them well. Because most patients’ cancer is quite advanced at diagnosis, this approach is often the only option anyway.
However, some patients receive a very early diagnosis either incidentally, meaning they underwent a surgical procedure for a different issue when mesothelioma was found; or because they presented with fluid buildup in the pleural space (called a pleural effusion) that prompted further testing. Recent staging studies suggest that this population of patients is significantly larger than previously thought and might include anywhere between 15% to 40% of diagnoses. For such patients, benefits of systemic therapies are unclear because studies that led to the FDA approval of chemotherapy and immunotherapy predominantly included unresectable (non-surgical candidates) stage 3 and 4 patients. Typically, early-stage patients are either offered surgery, or watchful waiting. But in the past year, this approach has been further complicated by a somewhat controversial surgical study called MARS 2 which showed limited benefits of surgery in the management of mesothelioma. Therefore, the expectation is that the number of early-stage patients who receive no immediate treatment will increase.
For this reason, the authors suggest that development of studies to test the effectiveness of localized intrapleural treatment is important and feasible and can be performed during the wait period between diagnosis and standard treatment, called window of opportunity.
In its early stages, mesothelioma’s only symptom might be a pleural effusion, either symptomatic or not. If symptomatic, once the effusion is drained, the patient feels better. But as long as mesothelioma is present on the pleura, it is rare for the fluid to stop building up. Currently, there are two ways to manage this problem:
- With a procedure called pleurodesis. The purpose of the procedure is to close the space in the pleura where fluid accumulates. This procedure makes the pleural space mostly inaccessible.
- By inserting a drain catheter into the pleural space to drain the fluid as it builds up, thus leaving the pleural space accessible.
Critically, administering intrapleural therapy will require access to the pleura, so the initial course of action for palliation of the pleural fluid will need to be reviewed and will require consensus among providers. It is important to note that a previous pleurodesis might not necessarily be a disqualifying factor as long as pleural pockets of air/fluid are still present.

Thanksgiving: Giving Thanks to all Those in the Mesothelioma Community
Holidays can be challenging when you or a loved one is dealing with a serious medical issue.
Thanksgiving is a day steeped in traditions; A time for turkey, football, family, and all the reasons to give thanks, we share these rituals with family and friends yearly. If this is the first one that you or your loved one are celebrating with a diagnosis of malignant mesothelioma chances are this one is different.
With the new perspective that comes with dealing with a rare cancer, and facing the unknown that is ahead, giving thanks takes on a new meaning. In addition to your usual support systems, this is a time to lean on the community that surrounds and tirelessly advocates for those afflicted with this mostly preventable cancer.
The mesothelioma community is an active group of family members, researchers, advocates, and caregivers all committed to supporting and advocating for patients and their families. From support groups, political activism, and advocates in the medical and legal community, the work moves forward. This small community continues to support and hopefully improve the lives of the victims and their families.
The mesothelioma community has made extensive accomplishments that slowly, and hopefully, will lead to a cure. We are grateful for the teams of researchers who have dedicated their lives to finding treatments for this complex cancer. The team consists of many people that work in behind-the-scenes labs that are required to complete this extensive work. It is not always successful, but they continue tirelessly, as each new day lays the stepping stones leading to a cure. Although the work is necessary and important, it often goes unnoticed. Without their contributions, there can be no new innovative therapies. We applaud and give thanks for their continued work.
Advocates within the mesothelioma community continue to work on behalf of all victims and their families. They have been working for decades now, to place into law, a nationwide ban on asbestos. The goal has never been closer. This could not be made possible without patients and family members who have made this their lives work advocating for a total ban on the leading cause of Malignant Mesothelioma, asbestos. Knowing the devastation that asbestos causes, they continue on so others may not have to suffer the losses they have. We applaud and give thanks for their continued work.
Caregivers of patients with Malignant Mesothelioma are constantly coordinating, researching, and helping the patients on a daily basis. These caregivers consist mostly of unpaid family members who sacrificed their time and energy, often at the cost of their own health. We applaud and give thanks for their continued work.
On this Thanksgiving, we want to take this time to give thanks to all those in the mesothelioma community that continue to support patients and their loved ones.
Happy Thanksgiving!

November is National Family Caregivers Month
It cannot be emphasized enough how important a role family caregivers can play in helping others maintain their optimum health.
Being diagnosed with Malignant Mesothelioma, a rare serious cancer affects the patient as well as the family and their loved ones. As with most diseases, often there is one person that ends up being the primary caretaker. This role is often one that the person did not plan on or is prepared for. The people that are affected by this disease can be anyone. The caregiver can be a family member, a son, a daughter, a husband, a wife, a friend, a neighbor, a relative, or anyone that steps into this vital role.
There are different types of caregivers, the most common ones are someone who takes care of a family member without pay. The other types are professional, independent, private, informal, and volunteer caregivers.
Every November we recognize all the people that are filling that role with National Family Caregivers Month. In the United States, there are over 65 million Americans who care for their aging or disabled loved ones. Of this number, 90% are unpaid care providers.
One in four people at some time in their lives are caregivers to family, friends, or neighbors who have either physical or mental conditions. Of this number, nearly a third are helping someone with mental illness.Those are just the statistics. The statistics do not tell the everyday life of the caregiver. They take care of people in need every day. Often the price the caregiver pays is their own health, mental and physical, and social wellbeings. It has been well documented that often the caregivers’ health suffers due to this role.
To put a face to these statistics, look around you. A few years ago while seeing a mesothelioma patient return to the clinic with his wife, I was struck by the toll that the disease had taken on his wife. The patient looked great, he was doing well and had a positive outlook. His wife, his primary caretaker, was not doing as well. She had lost weight, looked tired, and reported feeling depressed. Being the caretaker had taken a very visible toll on her.
Chances are you know someone, work with someone, or you are someone taking care of another person. Reach out to the caretaker, lend a hand, be specific, and ask if you can help at a specific hour on a specific day. If you can’t physically help, listen to the caretaker. Schedule a time to talk to them regularly. The role they play is a demanding and rewarding one that we can make easier by supporting them. Make their journey less isolating in November and throughout the year.
