This study is for patients with multiple myeloma (a type of blood cancer) that has come back or stopped responding to treatments. It looks at a new medicine, inobrodib, combined with other drugs: pomalidomide and dexamethasone. *Pomalidomide* and *dexamethasone* are commonly used cancer treatments. The study aims to see how well these drugs work together and to learn about any side effects.

• The study lasts for 28-day cycles, with certain days off from medication.
• About 100 patients will participate, and the drugs are taken orally (by mouth).
• Patients must be at least 18 years old and have specific prior treatments.

To join, you should not have any severe allergies to the study drugs or have taken certain treatments recently. Pregnant or breastfeeding women cannot participate. If you’re interested, ask your doctor if you meet the requirements and discuss any potential risks or benefits.
