Innovations in Treatment

Doctors and researchers are always on the lookout for new ways to treat malignant mesothelioma. The following innovations in treatment, while not a cure for malignant mesothelioma, show some promise in helping to treat the disease.
Alimta
Alimta, when given with another chemotherapy drug called cisplatin, is a chemotherapy drug recently approved by the FDA for the treatment of patients with malignant pleural mesothelioma.
Photodynamic Therapy
Photodynamic therapy uses special drugs and a special type of light to kill cancer cells during surgery. A drug that makes cancer cells more sensitive to light is injected into the patient’s vein several days before surgery. During surgery, a special light is used to locate the cancer. This treatment is being studied for early stages of malignant mesothelioma.
Immunotherapy
This type of treatment harnesses the power of the body’s own immune system. Immunotherapy is currently being researched as a treatment for malignant mesothelioma.
Gene Therapy
In studies of gene therapy for cancer, the goal is to improve the body’s natural ability to fight malignant mesothelioma directly or to make the cancer cells more sensitive to other kinds of therapy.
Brachytherapy
Brachytherapy is radiation therapy applied from within the body as opposed to from a machine outside the body. Radioactive sources are placed in or near the tumor, giving a high radiation dose to the tumor while reducing the radiation exposure in surrounding healthy tissues. This precision can help to minimize side effects.
Clinical Trials
A clinical trial (also clinical research) is a research study using human volunteers to answer specific health questions. Carefully conducted clinical trials help discover treatments that work in people and ways to improve health. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings. If you are interested in participating in a clinical trial, talk to your doctor about whether a clinical trial may be an appropriate option in your case.
Phase I
Phase I trials are considered the first step in testing the safety and efficacy of a new drug. Doctors and researchers are trying to determine many things about the drug’s effect on the disease and on the patient. Among the things that researchers are trying to determine are correct dosage, safety profile, and any side effects.
Phase II
At this stage, researchers select a relatively small group of patients to study the specific effects of the pre-determined dosage. Phase II studies also typically focus on a specific type of disease.
Phase III
During Phase III testing, researchers compare the effectiveness of the new, experimental drug against already existing therapies. Usually, patients are randomly assigned to therapeutic groups to cut down on the possibility of human bias. Phase III trials can be large, recruiting patients from across the country.
