Used primarily in the treatment of multiple myeloma and other hematological cancers. It functions as an immunomodulatory agent with anti-inflammatory and anti-angiogenic properties. Enhances T-cell activation and cytokine production while inhibiting the growth of tumor cells by interfering with cell cycle progression and inducing apoptosis. Commonly used in combination with dexamethasone for improved therapeutic outcomes. Also under investigation for use in solid tumors and autoimmune disorders due to its modulatory effects on the immune system.
