Clinical Trials Cancer

What Do We See For Future Cancer Treatment?

Clinical Trials Cancer

The clinical trials are research and findings related to this dreaded disease which is having a tight grip over the lives of many people. The cause is not known and we always fear the unknown. Sometimes though we feel that ignorance is bliss, in this case ignorance is a killer. It is better to be for warned and fore armed.

Hundreds of tests are conducted all over the world in the field of oncology. Animals are used for these tests. Rats and pigs are used for these tests.

Clinical Trials Cancer

Clinical trials are conducted in phases. There are four phases. They are:

Phase I: These trials determine the safety of a new treatment. Here the decision to introduce a new drug whether orally or intravenous is decided and the patient is watched for any allergy or symptoms relating to this new drug. Around twenty people who have already gone through the standard treatment and found no improvement are used as guinea pigs. These 20 people are divided into groups of four and given low dose drug and medium dose and higher dose respectively. Then they are monitored for side effects. Their urine and blood samples are constantly monitored to get results.

Phase II: These trials determine whether a certain kind of cancer responds to a new treatment. On successful completion of phase one trials the phase two progresses to see how well the new drug is working its way. These patients could have gone through chemotherapy and radio therapy. If the new treatment seems to be effective against cancer in a certain percentage of patients, researchers may consider it successful enough to continue study in a Phase III clinical trial.

Phase III: In this phase the trials study whether a new treatment is better than standard treatment. Here the treatment is monitored to see if there is any improvement in the condition of the patient. Researchers track whether a new treatment is better than, the same as, or less effective than the standard treatment. The patients are randomly selected and divided into two groups such as the control group and experimentation group.

Phase IV: Lastly the trials find more information about a new treatment that has been already approved for use in patients. Phase IV clinical trials are not as common as Phase I, Phase II and Phase III trials. In Phase IV trials, researchers study drugs and/or treatments that have already received FDA approval. The goal of Phase IV trials is to study how safe and effective a drug or procedure is over time.

Lastly the U.S (FDA) Food and Drugs Association is to make sure medical treatments are safe and effective for people to use. Based on this information, the FDA may approve the drug or treatment and makes it available to all patients as a new standard treatment.
