  • Female participants pregnant or breast-feeding. Pregnant women are excluded from this study because dabrafenib, and trametinib may have teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study drugs, breastfeeding should be discontinued if the mother is treated with the study drugs. Dabrafenib was teratogenic and embryotoxic in rats at doses three times greater than the human exposure at the recommended clinical dose.
  • A history or current evidence of retinal vein occlusion (RVO)
  • History of interstitial lung disease or pneumonitis
  • Patients with known human immunodeficiency virus (HIV) on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with dabrafenib and trametinib. In addition, these participants are at increased risk of lethal infections when treated with marrow-suppressive therapy.
  • Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the study treatments, their excipients, and/or dimethyl sulfoxide (DMSO).

About this study

Official title: An Open-label, Pilot Study of Dabrafenib and/or Trametinib in Patients With Relapsed and/or Refractory Multiple Myeloma

This research study is studying a targeted therapy as a possible treatment for multiple myeloma.

The names of the study drugs involved in this study are:

  • Trametinib
  • Dabrafenib
Read the detailed description

This research study is a Pilot Study, which is the first time investigators are examining this study drug in this disease. "Investigational" means that the combination of drugs is being studied. It also means that the FDA (U.S. Food and Drug Administration) has not approved the drugs for your type of cancer.

The FDA has not approved Trametinib or Dabrafenib for your specific disease but they have been approved for other uses.

Some cancers have changes (mutations) in a gene called BRAF or other genes, called KRAS or NRAS. These three genes tell the body to make a protein called BRAF, KRAS, or NRAS, respectively, which are all involved in sending signals in cells that can lead to cell growth. Certain mutations in these three genes cause a change in these proteins that can increase the growth and spread of cancer cells.

Dabrafenib and trametinib work to prevent these altered proteins from working and sending signals in cancer cells, and thereby may block the growth and spread of cancer cells in people with cancers with BRAF, KRAS, or NRAS gene mutations. Dabrafenib and trametinib have been used in the treatment for other cancers in other research studies, and information from those research studies suggest that these agents may help to kill multiple myeloma cells.

Dabrafenib and trametinib, which are investigated in this research study may or may not kill myeloma cells effectively. We would like to see if these drugs given alone or in combination safely and effectively kill these cancer cells.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dabrafenib and Trametinib in people with Multiple Myeloma, run by Massachusetts General Hospital at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 26 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 31 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate (time frame: 100 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2026.
