Combination Therapies with Selinexor for Multiple Myeloma
(STOMP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate the safety and effectiveness of different combinations of the drug selinexor for people with multiple myeloma, a type of blood cancer. Researchers are testing several combinations of selinexor with other medications to treat both newly diagnosed and previously treated cases. Currently, the trial seeks participants with relapsed or refractory multiple myeloma who have undergone at least two prior treatments, including specific drug types, and who are ineligible for T-cell therapies like CAR-T. As a Phase 1 and Phase 2 trial, it focuses on understanding the treatment's mechanism and measuring its effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are taking strong CYP3A4 inhibitors or inducers, you may need to stop them before participating in the PK Run-in period for certain trial arms.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that selinexor, when combined with other drugs, generally maintains a known safety profile. The FDA has approved selinexor, often used with dexamethasone and other medications, for treating multiple myeloma, supporting its safety for patients.
Studies have found the combination of selinexor, dexamethasone, and pomalidomide to be generally tolerable for patients with relapsed or refractory multiple myeloma. Common side effects include nausea and fatigue, which are usually manageable.
The combination of selinexor, dexamethasone, and belantamab mafodotin also maintains a known safety profile. However, belantamab can cause eye-related side effects, so patients receive close monitoring for any vision issues.
For the combination of selinexor, dexamethasone, and mezigdomide, selinexor and dexamethasone have been used safely together in other treatments. Mezigdomide, when combined with dexamethasone, has shown promising safety data, indicating it is well-tolerated, especially in patients who have tried other treatments.
Overall, while side effects can occur, they are often manageable, and previous studies have shown a good safety profile for these treatments. Patients should discuss any concerns with their healthcare providers to understand what to expect and how to handle potential side effects.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these combination therapies for multiple myeloma because they incorporate Selinexor, which works uniquely by blocking the protein XPO1, leading to cancer cell death. This mechanism is different from many standard treatments like proteasome inhibitors or immunomodulatory drugs. Additionally, combinations involving novel agents like Belantamab Mafodotin and Mezigdomide bring fresh approaches by targeting different pathways, potentially enhancing effectiveness and offering new hope for patients with resistant disease. Overall, these treatments aim to provide more options and improve outcomes for difficult-to-treat myeloma cases.
What evidence suggests that this trial's treatments could be effective for multiple myeloma?
Research has shown that combinations using selinexor are promising for treating multiple myeloma, especially in patients unresponsive to other treatments. In this trial, participants may receive different combinations of selinexor. For example, the combination of selinexor with pomalidomide and dexamethasone (SPd) reduced cancer in nearly 40% of patients. Another combination in this trial, selinexor with dexamethasone and daratumumab (SDd), proved very effective, benefiting 74% of patients whose cancer returned. Selinexor with carfilzomib and dexamethasone (SKd) also shows high success rates in patients who have undergone many previous treatments. While specific results for selinexor with dexamethasone and belantamab mafodotin (SBd) aren't detailed, studies suggest it could be beneficial. Lastly, the new combination of selinexor, dexamethasone, and mezigdomide (SMd) is under study for its unique effects, and early signs suggest it might help those with recurring or resistant multiple myeloma.12678
