Multiple myeloma is a blood cancer affecting plasma cells in the bone marrow. It's diagnosed in about 35,000 Americans each year, mostly over age 65. Treatment has changed dramatically in the past decade — many people now live years longer than was possible before, using combinations of targeted drugs, immunotherapy, and stem cell transplant.

What's actually going on in research

Trials are testing CAR-T cell therapy earlier in treatment, bispecific antibodies that redirect immune cells to kill myeloma, and combinations that might eliminate the need for chemotherapy. Researchers are also studying minimal residual disease testing to guide treatment decisions, and new drugs for high-risk myeloma that resists standard therapy.

CAR-T cell therapy

Two CAR-T therapies — idecabtagene vicleucel and ciltacabtagene autoleucel — were FDA-approved in 2021 and 2022 for relapsed myeloma. Trials are now testing whether using them earlier, after one or two prior treatments, produces better long-term outcomes.

Bispecific antibodies

These drugs connect a patient's T cells directly to myeloma cells, forcing the immune system to attack the cancer. Teclistamab became the first FDA-approved bispecific for myeloma in 2022, and several others are in late-stage trials.

Minimal residual disease

Ultra-sensitive tests can now detect one myeloma cell among a million normal cells. Trials are studying whether people who reach this level of response can safely stop treatment or skip stem cell transplant.

What to know before you search

Eligibility typically depends on how many prior treatments you've had, specific genetic features of your myeloma, kidney function, and blood counts.

What types of trials are currently open

  • Newly diagnosed trialsTesting new drug combinations or treatment sequences for people just diagnosed with myeloma. Many compare adding a new drug to standard induction therapy.
  • Relapsed myeloma trialsTesting treatments for myeloma that has returned after initial therapy. Often involve newer drug classes like bispecific antibodies or CAR-T cells.
  • Maintenance trialsStudying whether continuing certain drugs after initial treatment keeps myeloma in remission longer.
  • High-risk myeloma trialsTesting more intensive approaches for people whose myeloma has genetic features that predict poorer response to standard treatment.
  • Supportive care trialsTesting treatments for bone pain, fractures, kidney problems, infections, and other complications of myeloma or its treatment.
