Mesothelioma

Mesothelioma Drugs

New mesothelioma and anti-cancer drugs are constantly being researched and developed. Such drugs are required by the Food and Drug Administration (FDA) to go through extensive clinical trial testing during which their safety and efficacy is monitored.
The patients who choose to participate in these clinical trials typically suffer from a highly advanced type of cancer. Rather than electing to submit to traditional mesothelioma treatments that have proven ineffective in combating the rare asbestos cancer, patients can instead choose from a variety of experimental treatments. While such experimental treatments are more risk-oriented than traditional treatment modalities, they present cancer patients with a more proactive medium through which to fight to live.

Mesothelioma Drugs
Veglin

Vegin is a new experimental drug manufactured by VasGene Therapeutics, Inc., Veglin is an anti-angiogenesis drug undergoing clinical trials at the University of Southern California’s Keck School of Medicine. Veglin inhibits VEGF proteins, halting the formation of blood vessels and limiting the ability of tumors to grow and spread. Veglin is an antisense oligonucleotide, meaning that it can bond to messenger RNA (nucleic acid that directs protein production) and block the production of VEGF proteins.
If Veglin is successful in blocking tumor secretion of VEGF proteins, it is believed that it will be capable of preventing metastasis while simultaneously killing existing cancer cells.

ALIMTA [ (pemetrexed) is now available on expanded access basis.

ALIMTA is now available for people with malignant pleural mesothelioma, a cancer usually associated with exposure to asbestos. As of July 9, 2002 the Food and Drug Administration agreed to place ALIMTA in an expanded access program, which gives patients access to an agent that isn’t yet commercially available, although the sponsor is actively pursuing marketing approval. Eli Lilly is pursuing approval of ALIMTA in combination with cisplatin for the treatment of malignant pleural mesothelioma, a disease that causes tumors to grow in the linings of the lung, or pleura. Patients live an average of six to nine months following diagnosis. The company said results of a Phase III trial showed that patients treated with ALIMTA and cisplatin combined lived longer and had less pain and shortness of breath, than patients treated with cisplatin alone. In the trial, the most common side effect from cisplatin and ALIMTA was a decrease in infection- fighting white blood cells. Under the expanded access program, ALIMTA will be given free of charge to patients who meet medical eligibility requirements.

L-NDDP (aroplatin).

L-NDDP (aroplatin) Intrapleural administration is intended to exceed the usefulness of other platinum drugs like Cisplatin that are limited by toxicity and drug resistance.

Endostatin.

Endostatin has been shown to inhibit a tumor’s ability to grow blood vessels without destroying normal healthy cells. Works with angiostatin. Lovastatin. A cholesterol drug shown to potentially inhibit the growth of cancer cells.
Intrapleural interferon gamma.
The anti-cancer drug, Interferon Gamma is directly administered into the affected area.

A Word about Clinical Trials

Clinical trials are separated into four distinct phases:

Phase I & II: the first two phases of any clinical trial revolve around drug safety. Candidates for phases I & II include patients with an advanced form of a given disease (in this case, cancer), who are given the opportunity to try experimental treatments.
Phase III: the third phase of any clinical trial revolves around comparing the drug with standard forms of treatment proven to work. Participants of phase III have a more optimistic prognosis while also meeting clinical trial criteria.
Phase IV: the fourth and final phase of any clinical trial coincides with the preliminary marketing of the drug. Studies gather information on the drug’s effect in various populations while monitoring any long-term side effects.
Mesothelioma Treatment Options – Drug Therapy

Traditional Chemotherapy:
This traditional approach uses special anti-cancer (cytotoxic) medicines and chemicals to try to kill the malignant cells. Often, it is offered as an additional therapy alongside radical surgery and/or in combination with radiation therapy or immunotherapy, particularly when the cancer has spread beyond an operable area. Many drugs have been tried; however all have met with only limited success against malignant mesothelioma.
The chemotherapeutic agents can be administered either systemically (in the blood stream) or intrapleurally (in the pleural cavity itself.) These cytotoxic drugs are very potent and can have many severe side effects which you should discuss with your doctor.

Mesothelioma Screening

Mesothelioma screening means testing people for early stages of a disease before they have any symptoms. If you have signs and symptoms that might indicate mesothelioma cancer, your doctor will conduct a physical exam, paying particular attention to areas where you’re experiencing pain. He or she checks for any lumps or other unusual signs. Your doctor may order other tests to determine the cause of your signs and symptoms, including:

Chest X-ray. X-rays may show abnormalities if you have pleural mesothelioma.
Chest or abdominal CT scan. Computerized tomography (CT) may reveal abnormalities in your chest or abdomen if you have mesothelioma.
It’s not uncommon for mesothelioma to be misdiagnosed initially because mesothelioma is rare and its signs and symptoms aren’t specific. Your doctor will likely rule out other more common conditions before considering mesothelioma.

Mesothelioma Screening – Biopsy
Biopsy, a surgical procedure to remove a small portion of the mesothelium for laboratory examination, is the only way to determine whether you have mesothelioma. Depending on what area of your body is affected, your doctor selects the right biopsy procedure for you. Options include:

Fine-needle aspiration. The doctor removes fluid or a piece of tissue with a small needle inserted into your chest or abdomen.
Thoracoscopy. Thoracoscopy allows the surgeon to see inside your chest. In this procedure, the surgeon makes one or more small incisions between your ribs. He or she inserts a tube with a tiny video camera to see inside your chest cavity – a procedure sometimes called video-assisted thoracoscopic surgery (VATS). Special surgical tools allow your surgeon to cut away a piece of tissue.
Laparoscopy. Laparoscopy allows the surgeon to see inside your abdomen. Using one or more incisions into your abdomen, the surgeon inserts a tiny camera and special surgical tools to obtain a small piece of tissue for examination.
Thoracotomy. Thoracotomy is surgery to open your chest to allow a surgeon to check for signs of disease. He or she removes a sample of tissue for testing.
Laparotomy. Laparotomy is surgery to open your abdomen to allow a surgeon to check for signs of disease. He or she removes a sample of tissue for testing.
Once the tissue sample has been collected through biopsy, the sample is analyzed under a microscope. This determines whether or not the abnormal tissue is mesothelioma. Biopsy samples also allow your doctor to test for the type of cells involved in your mesothelioma. The type of mesothelioma you have is used to determine your treatment plan.
Other screening methods for diagnosis of asbestos-related disease include various imaging tests. In addition to X-rays, methods include magnetic resonance imaging (MRI) or positron emission tomography (PET). A more recent and promising screening method is the computed tomography (CT) scan.

Mesothelioma Lawsuit – Note of Urgency

The first lawsuits against asbestos manufacturers were in 1929. Since then, many lawsuits have been filed against asbestos manufacturers and employers, for neglecting to implement safety measures after the links between asbestos, asbestosis, and mesothelioma became known (some reports seem to place this as early as 1898).

A good Mesothelioma attorney understands the unique complexities involved in this kind of litigation lawsuit, including asbestos product identification, specific asbestos-related medical issues, and specific time constraints that narrow the window of opportunity to file a claim.

It is important to find the right Mesothelioma lawyer before your state’s statutes of limitations expires, leaving you and your family grieving and empty-handed. There’s no time to wait – contact our mesothelioma lawyers today for a free case review.
