Mesothelioma Clinical Trials

What Are Mesothelioma Clinical Trials?

Clinical research trials offer the latest therapies before they become widely available. Researchers use clinical trials to investigate more effective treatments. They also improve screening and diagnosis methods and uncover new ways of preventing disease. As of April 2022, more than 124 clinical research trials are actively recruiting mesothelioma patients.

Cancer research trials often last several years. They go through many phases. Once recruitment starts, enrollment may be paused. These checkpoints are for researchers to analyze the data. If results are inadequate, the study sponsor may suspend or terminate the study early.

Mesothelioma Clinical Trials Actively Recruiting Patients

Dozens of clinical trials are recruiting mesothelioma patients. The U.S. National Institutes of Health maintains a database of past and present clinical trials for mesothelioma malignancy.

How Clinical Trials Can Help Mesothelioma Patients

Clinical trials can be a valuable resource for mesothelioma patients. They offer access to promising new treatments. These therapies may not be available through standard treatment options. 

These trials are testing new treatments. Examples include experimental drugs that target specific proteins or pathways in cancer cells. Immunotherapy trials harness the power of the patient’s immune system to fight cancer.

By participating in a clinical trial, mesothelioma patients can benefit from these new treatments. They may help to improve their prognosis and quality of life. Experimental drugs, for example, can provide a targeted approach to treating cancer. Targeted drugs attack specific molecular pathways. These pathways are involved in the growth and spread of the tumor.

In some cases, clinical trials may offer the chance for patients to receive a combination of experimental therapies. These combinations have been shown to be effective in early studies. This approach can be particularly beneficial for mesothelioma patients. The disease often requires a multimodal therapeutic approach to achieve the best outcomes.

I want to be as helpful as I can. Being in a clinical trial has allowed me to do that, providing information to researchers about therapies that could help patients in the future. Sure, I was hoping it could help me, but it’s also rewarding when you know you’re helping others, which is what a clinical trial does.

Are Clinical Trials for Mesothelioma Safe?

Mesothelioma Clinical Trial Phases 1:13

Clinical trials always come with certain risks. The experimental treatment may not be as effective as anticipated. You could experience unexpected side effects that harm your health.

A mesothelioma clinical trial can last weeks, months or years. The time depends on the trial’s goal, the number of patients involved and the results. Most drugs have to pass through multiple phases of trials. It can take years before getting U.S. Food and Drug Administration approval.

Participation of patients with mesothelioma in clinical trials is essential if we are going to make progress and develop novel therapies.

How Successful Are Clinical Trials for Mesothelioma?

Not all patients will find success during a mesothelioma clinical trial. However, every patient in a clinical trial receives, at minimum, the current standard of care. Experimental therapy doesn’t always work. In that case, physicians discuss other options with their patients. 

If a trial is unsuccessful for most patients, the investigators will discontinue the study. Many factors determine effectiveness. These include treatment type, medical history and adverse effects. Successful mesothelioma clinical trials lead to more extensive studies and approved treatments. 

For example, a 2019 study published in The Lancet Oncology tested a combination of nivolumab and ipilimumab immunotherapy. The study found that 52% of pleural mesothelioma patients who received the combination had disease control for 12 weeks. For comparison, less than 30% of pleural mesothelioma patients achieved disease control in previous studies of second-line drugs. 

The success of this trial led to the FDA approval of Opdivo and Yervoy immunotherapy for pleural mesothelioma patients in October 2020. Studies like these help researchers determine which treatments have the potential as safe and effective new therapies. 

In 2023, researchers confirmed a new phase II study is underway investigating the synergistic effect of gavocabtagene autoleucel (gavo-cel). The researchers are testing gavo-cel with Opdivo and Yervoy. In early phase I results, 93% of patients experienced tumor regression.

What Are the Risks Associated With Mesothelioma Clinical Trials?

There are risks involved when trying a new therapy. Researchers understand these risks and set protocols to avoid them, such as closely monitoring patients for signs of toxicity and side effects. Mesothelioma clinical trials are designed to prioritize patient safety. 

Potential participants should consider the possible inconvenience. There is a traveling and time commitment in addition to potential side effects of treatment. The new treatments are still being tested. It is uncertain if they will be effective at treating mesothelioma.

Participating in a clinical trial can be emotionally challenging. It may involve uncertainty and the possibility of negative outcomes. Discuss the risks and benefits of joining a clinical trial with your doctor and your family.

Mesothelioma Clinical Trials Lead to New Treatments and Better Survival Rates

There is no cure for mesothelioma. Doctors are researching new therapies to improve survival rates and quality of life.

Sometimes a clinical trial results in a breakthrough. It can change the way doctors approach cancer treatment. For example, research studies led to FDA approval of the first mesothelioma chemotherapy option. They also led to the more recent Tumor Treating Fields.

Chemotherapy Trial of Cisplatin and Alimta

In 2003, one of the most important mesothelioma clinical trials announced its success. They study treated patients with a combination of the chemotherapy drugs Alimta (pemetrexed) and cisplatin. In 2004, the combination therapy was approved by the FDA to treat pleural mesothelioma.

Tumor Treating Fields (TTFields) Clinical Trial

Clinical trials led to the May 2019 FDA approval of Tumor Treating Fields. Together, chemotherapy and TTFields control the growth of pleural mesothelioma. The results of the trial that led to FDA approval showed an improved overall survival of more than six months.

This emphasizes the importance of patient participation. Many mesothelioma trials struggle to get enough participants to truly test a new drug or therapy. Joining a trial helps researchers get closer to developing a cure for mesothelioma.

How Do I Enroll in a Clinical Trial for Mesothelioma?

Most patients enroll in trials at the recommendation of their doctor. They generally know which clinical trials their patient may be eligible to join.

Cancer centers and clinics participating in research trials will typically have staff dedicated to running clinical trials. A research coordinator may reach out if you meet eligibility requirements.

Every mesothelioma clinical trial has specific criteria for who is eligible to participate. Some trials are only for patients who have not been treated before. Other trials are exclusively for patients who did not respond well to standard treatments.

Steps to Enroll in a Clinical Trial

Step 1: Talk to Your Doctor

Your oncologist can recommend clinical trials tailored to your diagnosis and medical history.

Step 2: Get a Second Opinion

Seek a second opinion from a mesothelioma specialist. It may open the door to other clinical trials.

Step 3: Which Trials Interest You?

Take the time to completely understand the trials that most appeal to you. Review and discuss the research trial information with your family. Together, you can determine if the trial expectations and stress may be too much to bear.

Step 4: Ask Questions and Finalize Your Decision

Ask your doctor as many questions as necessary to understand the risks and benefits of the trial. Once you’ve finalized your decision, your medical team will walk you through the necessary paperwork to begin the screening process.

Common Eligibility Factors of Clinical Trials

After you enroll in a clinical trial, research personnel will conduct a series of blood and imaging tests. These extra precautions ensure that you are eligible for the study. They also ensure that the experimental treatment won’t cause extra harm. Some requirements include patients who have metastatic cancer. Others may specify no prior therapy.

Questions to Ask Your Doctor Before Participating

Prior to enrolling, it is important for a mesothelioma patient to fully understand the details and purpose of the trial.
