Immunomodulators and Their Side Effects
Immunomodulators are a group of drugs that mainly target the pathways that treat multiple myeloma and a few other cancers. They have many ways to work, including working on the immune system directly by turning down some proteins and turning up others.
Thalidomide, lenalidomide, and pomalidomide
Thalidomide (Thalomid), lenalidomide (Revlimid), and pomalidomide (Pomalyst) are known as immunomodulating drugs (or IMiDs).
These drugs can cause side effects such as drowsiness, fatigue, constipation, low blood cell counts, and neuropathy (painful nerve damage). There is also an increased risk of serious blood clots (that start in the leg and can travel to the lungs). These tend to be more likely with thalidomide than with the other drugs.
These drugs can also cause severe birth defects if taken during pregnancy.
叠补肠颈濒濒耻蝉&苍产蝉辫;颁补濒尘别迟迟别-骋耻é谤颈苍
叠补肠颈濒濒耻蝉&苍产蝉辫;颁补濒尘别迟迟别-骋耻é谤颈苍 (BCG) is a germ that doesn’t cause serious disease in humans, but it does infect human tissues and helps activate the immune system. This makes BCG useful as a form of cancer immunotherapy. BCG was one of the earliest immunotherapies used against cancer and is still being used today.
BCG is used to treat early stage bladder cancer. It is a liquid put into the bladder through a catheter. BCG attracts the body’s immune system cells to the bladder, where they can attack the bladder cancer cells. Treatment with BCG can cause symptoms that are like having the flu, such as fever, chills, and fatigue. It can also cause a burning feeling in the bladder. BCG can also be used to treat some melanoma skin cancers by injecting it directly into the tumors. It's also used as a vaccine against tuberculosis.
Imiquimod
Imiquimod is a drug that is applied to the skin as a cream. It stimulates a local immune response against skin cancer cells. It is used to treat some very early stage skin cancers (or pre-cancers), especially if they are in sensitive areas such as on the face.
The cream is applied anywhere from once a day to twice a week for several months. Some people have serious skin reactions to this drug.
