Multiple Myeloma

Multiple myeloma is a blood cancer that develops in the bone marrow, the soft, spongy tissue found in the center of many bones where blood cells are produced. In myeloma, plasma cells, which are normal antibody-producing cells, transform into cancerous myeloma cells.

Myeloma cells produce large quantities of abnormal antibodies (or immunoglobulins) called monoclonal (M) proteins, as well as incomplete parts of antibodies (called light chains or Bence-Jones proteins). These cancer cells crowd out and inhibit the production of normal blood cells and antibodies in the bone marrow.

Multiple myeloma is the second most common blood cancer in the world with approximately 30,000+ new cases diagnosed in the U.S. each year. As there is currently no cure for this disease, patients will typically progress following currently available treatments. There are approximately 120,000 Americans currently living with multiple myeloma and this number is expected to rise with advances in treatment.

Signs and Symptoms of Multiple Myeloma

Multiple myeloma is a debilitating disease with many different signs and symptoms.

These symptoms and complications can include:

  • Low blood counts
  • Bone loss / bone pain
  • Infections
  • Kidney impairment
  • Anemia and fatigue
  • Weight loss

Treatment for Multiple Myeloma

There are a number of therapies currently available to treat patients with multiple myeloma. However, despite continued advances, multiple myeloma remains an incurable disease which is why additional research and development of new therapies remains so important.

Relapsed or Refractory Multiple Myeloma

There have been remarkable advances in the treatment of myeloma and for many patients, myeloma will become a chronic illness.

When myeloma responds to treatment, symptoms may improve or even go away, and patients are said to enter a period of time called a remission.  

For most patients with myeloma, a remission is followed by a period of time when symptoms and the disease return. This is called a relapse.

Multiple myeloma is described as refractory when the disease does not respond to treatment or there is a relapse within 60 days of stopping a new treatment.

Karyopharm’s Focus in Multiple Myeloma

At Karyopharm, much of our clinical development is focused on treating patients with relapsed or refractory multiple myeloma and our investigational drugs are being studied when used in combination with low dose steroids, as well as in combination with other commonly prescribed myeloma drugs such as immunomodulatory drugs, proteasome inhibitors, and monoclonal antibodies.
