Introduction: What is Mesothelioma?
Mesothelioma is a life-threatening form of cancer that affects the lining of the lungs or abdomen. It is primarily caused by exposure to asbestos fibers, which can enter the body through inhalation or ingestion. Asbestos was widely used in building materials, insulation, and other products until the 1970s, and the effects of exposure can take decades to manifest.
Unfortunately, there is currently no cure for mesothelioma, and treatment options are limited. However, recent research has shown that a drug called Alimta may be able to slow the progression of the disease and improve the quality of life for patients. In this article, we will explore the benefits of Alimta and how it is being used to treat mesothelioma.
What is Alimta?
Alimta, also known as pemetrexed, is a chemotherapy drug that is used to treat several types of cancer, including mesothelioma. It works by inhibiting the growth and spread of cancer cells, preventing them from dividing and replicating. Alimta is often used in combination with another drug called cisplatin, which enhances its effectiveness.
How does Alimta work?
Alimta works by inhibiting several enzymes that are necessary for the growth and reproduction of cancer cells. One of these enzymes is thymidylate synthase, which is involved in the production of DNA. By blocking this enzyme, Alimta prevents cancer cells from dividing and multiplying. Alimta also inhibits other enzymes that are involved in protein synthesis and cell division.
What are the benefits of Alimta?
The primary benefit of Alimta is that it can slow the progression of mesothelioma and improve the patient’s quality of life. In clinical trials, patients who received Alimta in combination with cisplatin had a longer survival rate than those who received cisplatin alone. Alimta has also been shown to reduce symptoms such as pain and difficulty breathing.
How is Alimta administered?
Alimta is administered intravenously, usually over a period of 10-15 minutes. Patients typically receive treatment once every three weeks, with cisplatin also being given at the same time. The dosage and frequency of treatment may vary depending on the patient’s condition and response to the medication.
What are the side effects of Alimta?
Like all chemotherapy drugs, Alimta can cause side effects. The most common side effects include nausea, vomiting, fatigue, and loss of appetite. It can also cause low white blood cell count, which can increase the risk of infection. Rarely, Alimta can cause more serious side effects such as renal failure or liver damage. Patients should always discuss potential side effects with their doctor before starting treatment.
How effective is Alimta?
Alimta has been shown to be effective in slowing the progression of mesothelioma and improving the patient’s quality of life. In clinical trials, patients who received Alimta in combination with cisplatin had a median survival time of 12.1 months, compared to 9.3 months for those who received cisplatin alone. However, it is important to note that every patient is different and may respond differently to treatment.
How much does Alimta cost?
The cost of Alimta can vary depending on several factors, including the patient’s insurance coverage and the dosage and frequency of treatment. According to GoodRx, the average retail price of Alimta is around $5,000 for a single dose. However, many patients may be eligible for financial assistance through organizations such as the Mesothelioma Applied Research Foundation or the Patient Advocate Foundation.
The Use of Alimta in Treating Mesothelioma
Alimta was approved by the U.S. Food and Drug Administration (FDA) in 2004 for the treatment of malignant pleural mesothelioma, which affects the lining of the lungs. Since then, it has become a standard treatment option for mesothelioma patients.
Clinical Trials
The effectiveness of Alimta in treating mesothelioma has been studied extensively in clinical trials. In a phase III clinical trial, patients who received Alimta in combination with cisplatin had a median survival time of 12.1 months, compared to 9.3 months for those who received cisplatin alone. Another study found that Alimta and cisplatin reduced the risk of disease progression by 25% compared to cisplatin alone.
Real-World Applications
In addition to clinical trials, Alimta has been used in real-world settings to treat mesothelioma patients. A study of over 1,100 patients found that those who received Alimta in combination with cisplatin had a longer median survival time than those who received cisplatin alone. Another study found that Alimta and cisplatin were effective in palliating symptoms such as dyspnea (difficulty breathing) and chest pain.
Limitations
While Alimta has been shown to be effective in slowing the progression of mesothelioma, it is not a cure. The disease can still progress even with treatment, and patients may experience side effects from the medication. In addition, not all patients are eligible for treatment with Alimta, and it may not be the best option for everyone.

FAQs
What are the early signs of mesothelioma?
The early signs of mesothelioma can include shortness of breath, chest pain, coughing, and fatigue. It is important to see a doctor if you experience any of these symptoms, especially if you have a history of asbestos exposure.
How is mesothelioma diagnosed?
Mesothelioma is typically diagnosed through a combination of imaging tests (such as X-rays or CT scans) and a biopsy, which involves taking a sample of tissue for examination under a microscope.
Can mesothelioma be cured?
Unfortunately, there is currently no cure for mesothelioma. Treatment options are focused on slowing the progression of the disease and improving the patient’s quality of life.
What is the life expectancy for someone with mesothelioma?
