Targeted therapies are a type of cancer treatment that target cancer cells, specifically. They mostly spare healthy cells. Other treatments, like chemotherapy, can damage normal cells too.

These days, most of the drugs we use are targeted therapies. These include bortezomib, lenalidomide, carfilzomib, daratumumab, and many others.

Most people with myeloma will receive a targeted therapy. The type of targeted therapy you receive will depend on the your circumstances. For example, if you have a specific translocation, you might be eligible for a drug like venetoclax. In the future, we will also have specific drugs for KRAS mutations or other mutations of myeloma.

The duration of your treatment will depend on whether you’re newly diagnosed, or if you went into remission and your cancer has relapsed.

Yes. Every drug has side effects. The type of side effects you experience will depend on your overall treatment plan. Side effects of targeted therapy for multiple myeloma can include fatigue, nausea, diarrhea, infections, and more.

If you start experiencing side effects while on targeted therapy, talk to your doctor. They can help you with ways to manage any side effects, and let you know if there is medication to help.

To determine whether you’ll receive targeted therapy, your doctor will consider things like:

  • your age
  • your treatment history
  • the type of myeloma you have
  • your overall health
  • your preferences

Targeted therapy is sometimes used in combination with other cancer treatments like chemotherapy, stem cell transplant, or radiation.

Targeted therapy may come in the form of a pill that you take orally, or as an injection.

You will continue to see your doctor regularly during your treatment. How often you’ll need to see your doctor depends on your specific circumstances.

At these visits, you’ll have an exam and any tests as needed. This is so your doctor can check the progress of your treatment and that it’s working.
