What is the purpose of this trial?

This trial explores whether iberdomide, a new potential drug, can serve as a safe and effective ongoing treatment for people with Multiple Myeloma who have undergone a stem cell transplant and previously used lenalidomide as maintenance therapy. The trial aims to determine if iberdomide can help control the cancer after other treatments. It may be suitable for those who received a stem cell transplant within the last 15 months and have not experienced disease progression after using lenalidomide. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, ongoing treatment with chronic immunosuppressants is not allowed, and you must be willing to take DVT prophylaxis while on iberdomide maintenance.

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

Research has shown that iberdomide is generally safe for people with multiple myeloma. Previous studies found that patients tolerated iberdomide well when combined with other treatments like dexamethasone. No unexpected safety problems occurred, and it proved effective for those who had already tried many treatments. This suggests that iberdomide is a well-tolerated option, even for those with extensive treatment histories. Although this trial is in an early stage, consistent safety results from other research indicate its safety. ^{1 2 3 4 5}

Why are researchers excited about this study treatment for Multiple Myeloma?

Iberdomide is unique because it offers a new approach to treating multiple myeloma by modulating the immune system. Unlike standard treatments such as lenalidomide and bortezomib, iberdomide targets specific proteins that degrade harmful cells, potentially leading to more effective control of the disease. Researchers are excited about iberdomide because its novel mechanism may result in fewer side effects and improved outcomes for patients who have already undergone several treatments. This could be a game-changer for those with limited options due to relapsed or refractory multiple myeloma.

What evidence suggests that iberdomide might be an effective treatment for Multiple Myeloma?

Research has shown that iberdomide can help treat multiple myeloma. This trial studies iberdomide as a maintenance therapy for participants who have undergone prior treatments. In previous studies, when combined with other drugs, it achieved a 93.1% success rate in patients who are frail and cannot undergo a transplant. Another study found that it helped people live longer when their multiple myeloma returned or did not respond to other treatments. The treatment targets specific proteins in cancer cells, making it harder for them to survive and grow. These findings suggest that iberdomide could be a promising option for ongoing treatment in multiple myeloma. ^{1 5 6 7 8}

In a study of 198 patients with advanced-stage multiple myeloma, ibandronate did not significantly reduce the occurrence of skeletal-related events (SREs) or improve survival compared to placebo over a treatment period of 12 to 24 months.

However, patients receiving ibandronate who had a significant reduction in bone-turnover markers experienced less bone morbidity, suggesting that monitoring these markers could help identify patients who may benefit from treatment.
