What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new combination of treatments for certain cancers, such as non-Hodgkin or Hodgkin lymphoma and multiple myeloma, that have not responded to previous treatments. Researchers are testing how choline salicylate, an anti-inflammatory drug, works with selinexor, a drug that may inhibit cancer cell growth. The goal is to determine the best dose and identify any side effects. People with these cancers, especially if previous treatments failed, might be suitable candidates. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the chance to be among the first to receive this new combination therapy.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, if you are on active anticoagulant therapy with certain medications like direct oral anticoagulants, aspirin, or warfarin, you may not be eligible, except for low-dose aspirin (81 mg) for heart disease prevention, which must be paused during the trial.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Previous studies have led to FDA approval of selinexor for treating multiple myeloma and certain types of lymphoma, indicating it has been tested for safety in some patients. Common side effects include nausea, tiredness, and low blood platelet counts, which can affect blood clotting. Many patients find these side effects manageable.

Choline salicylate, similar to aspirin, reduces swelling and pain. Lab tests have combined it with selinexor, showing promise in treating blood cancers. Safety data suggests it is generally well-tolerated, but like aspirin, it may cause stomach upset or bleeding in some individuals.

Researchers are testing both treatments together to determine the best dose with the fewest side effects. This is an early phase study, so while some safety information is available, more data is needed to fully understand how well this combination is tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of selinexor and choline salicylate for treating lymphoma and multiple myeloma because it offers a fresh approach. Unlike traditional chemotherapy and targeted therapies, selinexor works by inhibiting the export of tumor suppressor proteins from the nucleus, potentially enhancing the body's natural ability to fight cancer. Meanwhile, choline salicylate, a salicylate-based anti-inflammatory, may help to manage inflammation and pain associated with these cancers. This dual-action approach could provide a more comprehensive treatment strategy, potentially improving outcomes for patients who have limited options with current therapies.

What evidence suggests that selinexor and choline salicylate might be an effective treatment for lymphoma and multiple myeloma?

Research has shown that selinexor, when adjusted to the right dose, improves treatment outcomes for multiple myeloma, particularly in patients with recurrent cancer. Studies have also found that combining selinexor with other drugs can be both effective and safe for treating multiple myeloma and diffuse large B-cell lymphoma. In this trial, participants will receive a combination of selinexor and choline salicylate. Choline salicylate, an anti-inflammatory drug, may enhance selinexor's cancer-fighting ability by reducing the immune response and inhibiting cancer cell growth. Early results suggest that this combination might be beneficial when previous treatments have failed. The goal is for these drugs to better control conditions like lymphoma, multiple myeloma, and histiocytic/dendritic cell neoplasm by preventing cancer cell growth. ^{3 4 5 6 7}
