Spots Global Cancer Trial Database for Leflunomide for the Treatment of High-Risk Smoldering Multiple Myeloma

Study Description

Brief Summary: This pilot trial studies how well leflunomide works for the treatment of patients with high-risk smoldering plasma cell myeloma, for the delay of disease progression. Anti-inflammatory drugs, such as leflunomide lower the body's immune response and are used with other drugs in the treatment of some types of cancer. The information learned from this study will help researchers to learn more about the anti-myeloma activity of leflunomide, and whether it may delay the onset of symptomatic multiple myeloma in patients with high-risk smoldering multiple myeloma.

Detailed Description: PRIMARY OBJECTIVE: I. To estimate the anti-myeloma activity of leflunomide, when given as a single agent, as assessed by 6-month progression-free response rate based on International Myeloma Working Group (IMWG) criteria. SECONDARY OBJECTIVES: I. To evaluate the safety and tolerability of single agent leflunomide. II. To summarize and assess toxicities by type, frequency, severity, attribution, time course and duration. III. To estimate overall and progression-free survival probabilities. IV. To estimate response rate and duration of response. V. To describe the impact of treatment on quality of life, as assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) Score version (v)3.0. EXPLORATORY OBJECTIVES: I. To characterize the molecular evolution of the tumor cells. II. To evaluate whether specific genetic subtypes respond differently to leflunomide. III. To evaluate the role of immune cells in the progression of smoldering multiple myeloma (SMM). IV. To evaluate the role of leflunomide in modulating the immune system. V. To examine the relationship between immunological changes and disease progression. OUTLINE: Patients receive leflunomide orally (PO) once daily (QD). Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After the completion of study treatment, patients are followed up at 30 days, every 28 days until an alternative myeloma therapy has commenced or until disease progression, and then up to 6 months.
