NCT00553189
Background: * PARP is an enzyme that is involved in the repair of damage to DNA. Levels of the enzyme are higher in tumor cells than in normal cells, and may play a part in resistance to cancer chemotherapy and radiation therapy. ABT-888 is an experimental drug that inhibits PARP and may help to increase the effectiveness of cancer treatments designed to damage DNA in cancer cells. * Topotecan is a drug approved by the Food and Drug Administration for treating certain cancers. * This dose escalation study will test the two drugs at successively higher doses in small groups of patients until the highest safe dose is determined. Objectives: * To test the safety of the combination of ABT-888 and Topotecan (TPT) and determine the highest dose of each drug that can be safely given to humans. This is the maximum tolerated dose (MTD). * To learn how the combination of ABT-888 and TPT works in humans and how the body handles the drugs. * To determine the side effects of the combination of ABT-888 and TPT at the tested doses. Eligibility: -Patients with solid tumors, lymphomas and chronic lymphocytic leukemia whose disease has progressed following standard therapy or for whom standard treatments are not available. Design: * ABT-888 and TPT are given in 21-day treatment cycles. At the start of the study, TPT is infused through a vein over 30 minutes about a week before cycle 1 starts. Starting on day 1 of cycle 1, ABT-888 is given by mouth twice a day for 7 days. TPT is given through a vein daily for 4 days starting on day 2. After the last dose of ABT-888 day 7, no more treatment is given for the rest of the 21-day cycle. * For the remaining cycles, ABT-888 is given twice a day by mouth on days 1 to 7 of each cycle, and TPT is given through a vein daily on days 1 to 5 of each cycle. * The first three to six patients enrolled in the study take the smallest study dose of the drugs. If they do not develop significant adverse side effects, successive small groups of patients take the drug at increasingly higher doses until the MTD is reached. Additional patients enrolled receive the MTD. * Patients have periodic clinic visits for their TPT infusions and for tests and examinations. Evaluations include measurement of vital signs, physical examinations, blood and urine tests, electrocardiograms and CT or other imaging tests, such as ultrasound or MRI. Tumor biopsies may be requested to study the effects of the drugs on the...
NCT00705809
Background: * The T-Cell Project, sponsored by the International T-cell non-Hodgkin Lymphoma Study Group, is a consortium of institutions interested in achieving more detailed information on clinical and biological characteristics of T-cell lymphomas. * The T-Cell Project serves as a repository for data on patients with peripheral T-cell lymphoma (PTCL) worldwide. Its overall goal is to improve T-cell subtype classifications and evaluate treatment strategies for each subtype. Objectives: -To implement a standardized epidemiologic questionnaire into the ongoing T-Cell Project to allow evaluation of various potential risk factors for PTLCs. Eligibility: -Untreated patients 18 years of age and older who were diagnosed with PTLC September 1, 2006, or later. Design: -Patients complete a questionnaire containing the following information: Demographic information Smoking history and alcohol use Personal history or cancer History of cancer among first-degree relatives Medical history History of transplants History of blood transfusions Medication use Occupational and residential history Pesticide treatment -The information collected is linked to clinical and pathologic information in the T-Cell Project database.
