Trial of the Combination of Bortezomib and Clofarabine in Adults With Relapsed Solid Tumors

Background: - Researchers want to develop better ways to treat cancer. In this study, they will give people with cancer two drugs. These drugs have been used on their own to treat some blood cell cancers. Objectives: - To test the safety and efficacy of the drug combination of bortezomib and clofarabine. Eligibility: - Adults age 18 and over with advanced cancer that has progressed after receiving standard treatment or that has no effective therapy. Design: Participants will be screened with medical history, physical exam, and scans to measure their tumors. They will also have heart, blood, and urine tests. All of these may be done by their regular doctors. Participants will get the study drugs in 21-day cyles. They will stay at the clinic for week 1 of every cycle, then have 2 weeks off. <TAB>- Bortezomib will be injected under the skin on days 1 and 4. <TAB>- Clofarabine will be injected in a vein for days 1-5. During cycle 1 only, participants will go to the clinic or their doctor to have a physical exam and blood tests at the start of the second and third week. Participants will have clinical evaluations throughout the study, including before receiving treatment and then before the start of each cycle. Participants may stay in the study as long as they are tolerating the drugs and their tumor is not getting worse. Participants will have follow-up for 30 days after the last dose of study drugs. The first part of this study tests the safety of different doses of clofarabine and bortezomib. The second part of this study involves a separate group of participants who will undergo mandatory research biopsies to learn more about the effects of clofarabine and bortezomib on cancer cells.
