Introduction
According to the World Health Organization, cancers are one of the leading causes of morbidity and mortality worldwide, and their incidence is expected to increase in the coming years. Mesothelioma is a rare type of cancer that affects the lining of certain organs, usually the lungs or abdomen. It is typically caused by exposure to asbestos and can take years to develop. This type of cancer is notoriously difficult to treat, and traditional therapies such as chemotherapy and radiation have had limited success.
However, there is hope on the horizon for mesothelioma patients. Pembrolizumab, a drug that has shown promise in treating other types of cancer, is being tested in clinical trials for its efficacy in treating mesothelioma. In this article, we will explore the Pembrolizumab Mesothelioma Trial, its promising results, and what it means for the future of cancer treatment.
What is Pembrolizumab?
Pembrolizumab, also known by its brand name Keytruda, is a type of immunotherapy drug that works by blocking the activity of a protein called PD-1 on T-cells. This protein normally helps regulate the immune system and prevent it from attacking healthy cells in the body. However, some cancer cells can produce a protein called PD-L1 that binds to PD-1 and prevents T-cells from recognizing and attacking them. By blocking PD-1, pembrolizumab allows T-cells to recognize and attack cancer cells.
How Does Pembrolizumab Work?
Unlike traditional cancer treatments such as chemotherapy and radiation, which target all rapidly dividing cells in the body, pembrolizumab specifically targets cancer cells while leaving healthy cells alone. This makes it a more targeted and less toxic treatment option with potentially fewer side effects than traditional therapies.
What is the Pembrolizumab Mesothelioma Trial?
The Pembrolizumab Mesothelioma Trial is a clinical trial that is testing the efficacy of pembrolizumab in treating mesothelioma. The trial is sponsored by Merck, the company that produces pembrolizumab, and is being conducted at multiple sites worldwide.
What Are the Results of the Pembrolizumab Mesothelioma Trial?
The results of the Pembrolizumab Mesothelioma Trial have been promising. In a phase 1b study, pembrolizumab was given to 25 patients with mesothelioma who had previously received at least one type of chemotherapy. Of these patients, 20% had a partial response to the treatment, meaning their tumors shrank by at least 30%. Additionally, 68% of patients had stable disease, meaning their tumors did not grow or shrink significantly. The median overall survival was 18.2 months, and the treatment was generally well tolerated with few serious side effects.
Who is Eligible for the Pembrolizumab Mesothelioma Trial?
The eligibility criteria for the Pembrolizumab Mesothelioma Trial vary depending on the specific study being conducted. However, in general, patients must have a confirmed diagnosis of mesothelioma and have received at least one type of chemotherapy prior to enrolling in the trial. Patients may also need to meet certain other criteria, such as having measurable disease on imaging scans and a certain level of overall health.
What Are the Potential Side Effects of Pembrolizumab?
Like any treatment, pembrolizumab can cause side effects. However, because it is a targeted therapy, it may have fewer side effects than traditional treatments such as chemotherapy and radiation. Common side effects include fatigue, nausea, diarrhea, and skin rash. More serious side effects can occur, such as pneumonitis (inflammation of the lungs) and hepatitis (inflammation of the liver), but these are rare.

FAQs
How long does each treatment with pembrolizumab last?
The length of treatment with pembrolizumab can vary depending on the patient’s individual case and the stage of their cancer. In some cases, patients may receive pembrolizumab for several months, while in others it may be given for a longer period of time.
Is pembrolizumab only used to treat mesothelioma?
No, pembrolizumab is used to treat a variety of different types of cancer. It has been approved by the FDA to treat melanoma, non-small cell lung cancer, head and neck squamous cell carcinoma, and classical Hodgkin lymphoma.
What is the cost of pembrolizumab?
The cost of pembrolizumab can vary depending on a number of factors, including the patient’s insurance coverage and the dosage they require. However, it is generally an expensive treatment, with some estimates placing the cost at over $150,000 per year.
How is pembrolizumab administered?
Pembrolizumab is administered intravenously, meaning it is given through a vein in the arm. Patients typically receive the treatment in an outpatient setting, such as a clinic or hospital.
What are the chances of a patient with mesothelioma responding to pembrolizumab?
The chances of a patient with mesothelioma responding to pembrolizumab can vary depending on a number of factors, including the patient’s overall health, the stage of their cancer, and the genetic makeup of their tumor. However, clinical trials have shown that a significant proportion of patients have responded positively to the treatment.
What is the mechanism of action of pembrolizumab?
Pembrolizumab works by blocking the activity of a protein called PD-1 on T-cells. This protein normally helps regulate the immune system and prevent it from attacking healthy cells in the body. By blocking PD-1, pembrolizumab allows T-cells to recognize and attack cancer cells.
What are the advantages of pembrolizumab over traditional cancer treatments?
One of the main advantages of pembrolizumab over traditional cancer treatments such as chemotherapy and radiation is that it specifically targets cancer cells while leaving healthy cells alone. This makes it a more targeted and less toxic treatment option with potentially fewer side effects. Additionally, pembrolizumab has shown promise in treating cancers that are resistant to traditional therapies.
What are the potential risks of participating in the Pembrolizumab Mesothelioma Trial?
Participating in a clinical trial always carries some risks. However, the Pembrolizumab Mesothelioma Trial has been designed with patient safety in mind, and every effort is made to minimize any potential risks. Patients who choose to participate in the trial will be carefully monitored by healthcare professionals throughout the study.
What happens after the Pembrolizumab Mesothelioma Trial?
After the Pembrolizumab Mesothelioma Trial is completed, the data collected will be analyzed to determine the safety and efficacy of the treatment. If the results are promising, pembrolizumab may be approved by regulatory bodies for use in treating mesothelioma. Patients who have participated in the trial will receive follow-up care from their healthcare providers.
What is the expected timeline for pembrolizumab to be approved for use in treating mesothelioma?
The timeline for pembrolizumab to be approved for use in treating mesothelioma will depend on the results of the clinical trials and the regulatory approval process. However, it is estimated that it could take several years before the treatment is widely available.
Are there any alternative treatments for mesothelioma?
There are a variety of different treatments for mesothelioma, including surgery, chemotherapy, and radiation. However, these treatments have had limited success in treating the disease, which is why the development of new treatm
ents such as pembrolizumab is so important.
What should patients with mesothelioma do if they are interested in participating in the Pembrolizumab Mesothelioma Trial?
Patients with mesothelioma who are interested in participating in the Pembrolizumab Mesothelioma Trial should speak with their healthcare provider. They can also visit clinicaltrials.gov for more information on the trial and how to enroll.
How can patients with mesothelioma access pembrolizumab?
Pembrolizumab is a prescription drug that can only be accessed through a healthcare provider. Patients who are interested in the treatment should speak with their healthcare provider about whether it is an appropriate option for them.
