A Pilot Study of the Safety and Efficacy of Escalating Doses of ON 01910.Na in Patients With Relapsed Mantle Cell Lymphoma, Multiple Myeloma, Chronic Lymphocytic Leukemia, and Related Lymphoid Malignancies
In Brief
A Phase 1 clinical trial evaluating ON01910 Na for Lymphoma, Mantle-cell and 4 related conditions. Completed, enrolled 16 participants across 1 site.
Detailed Summary
Background: * Mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), multiple myeloma (MM), and other lymphoid malignancies are all incurable lymphoid malignancies that mainly affect persons in their late 60s and early 70s. Conventional chemotherapy can achieve high rates of clinical response, but relapse following these responses is almost universal. Patients with lymphoid malignancies relapse because their tumor cells become resistant to chemotherapy; therefore, new types of drugs are needed for better treatment responses. * The investigational drug ON 01910.Na has been shown to be active against MCL and CLL cells, but further research is needed to determine the most safe and effective dose for this drug. Objectives: * To determine the maximum tolerated dose (the highest dose that does not cause unacceptable side effects) of ON 01910.Na in patients with cancers of the lymphoid cells. * To study the effects that ON 01910.Na has on cancers of the lymphoid cells. Eligibility: * Patients 18 years of age and older who have been diagnosed with cancer of the lymphoid cells, and who have not been able to take or have not benefitted from existing treatment options. Design: * Evaluations before the treatment period: * Full medical history and physical examination, and pregnancy test for women. * Blood and urine tests. * Disease evaluation with computerized tomography (CT) scan, magnetic resonance imaging (MRI), electrocardiogram; bone marrow and lymph node biopsies; and skeletal x-rays, if clinically indicated. * Treatment with ON 01910.Na: * Different research subjects will receive increasing doses of ON 01910.Na to determine which dose is considered safe. * To reduce the risk of one rare serious side effect of treatment for myeloid malignancies, patients will take allopurinol 12 hours before and 7 days after each drug infusion, one 300 mg pill each day. * Cycles 1 2: Patients will be admitted to the clinical center for 2 days at the beginning of each cycle. Each cycle involves intravenous infusion of ON 01910.Na continuously for a period of 48 hours, followed by 12 days of observation. Researchers will try to maintain the schedule of 2 days of infusion every 14 days, but the interval between doses may be extended if patients experience delayed recovery blood counts. * Cycles 3 4: Patients who are doing well and choose to continue may receive an additional two cycles (2 days of inpatient infusion followed by 12 days of outpatient observation). At the end of cycle 4, researchers will determine if the disease is responding to therapy. Patients who experience side effects may continue to take ON 01910.Na at a lower dose or may stop receiving the drug. * Patients who respond well to four cycles of ON 01910.Na may be eligible for additional cycles of ON 01910.Na. * Patients who need to start another medication to treat their disease will stop taking ON 01910.Na, and the researchers will perform a final study visit 2 weeks after the last dose of ON 01910.Na. After that, participation in the study will be complete.
