- 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.


- To test the safety and efficacy of the drug combination of bortezomib and clofarabine.


- Adults age 18 and over with advanced cancer that has progressed after receiving standard treatment or that has no effective therapy.


- 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.

-- Bortezomib will be injected under the skin on days 1 and 4.

-- 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 a clinical evaluation throughout the study, before the start of each cycle, before receiving treatment.

- 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.

Patients must have:

3.1.1 Histologically confirmed solid tumors that have progressed on standard therapy known to prolong survival or for which no standard treatment options exist, or histologically confirmed myelodysplastic syndrome that has progressed on standard therapy or for which no standard treatment options exist.

3.1.2 Age greater than or equal to18 years.

3.1.3 ECOG performance status less than or equal to 2.

3.1.4 Life expectancy of greater than 3 months

3.1.5 Patients must have normal organ and marrow function as defined below:

-Absolute neutrophil count: greater than or equal to 1,500/mcL for solid tumors and lymphomas only

-Platelets: greater than or equal to 100,000/mcL for solid tumors and lymphomas only

-Total bilirubin: less than or equal to 1.5 X institutional ULN

-AST(SGOT)/ALT(SGPT): less than or equal to 3 X institutional upper limit of normal

creatinine: ess than or equal to 1.5 X institutional ULN


creatinine clearance greater than or equal to 60 mL/min/1.73 m2 for patients with creatinine levels >1.5 mg/dL

3.1.6 Bortezomib and clofarabine have both been assigned to pregnancy category D by the FDA. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for at least 3 months after dosing with study drugs ceases. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 3 months after completion of study drug administration.

3.1.7 Patients must have completed any chemotherapy, radiation therapy, or biologic therapy greater than or equal to 3 weeks (or greather than or equal to 5 half-lives, whichever is shorter) prior to entering the study. Patients must be greater than or equal to 2 weeks since any prior administration of a study drug in a Phase 0 or equivalent study and be greater than or equal to 1 week from palliative radiation therapy. Patients must have recovered to eligibility levels from prior toxicity or adverse events. Treatment with bisphosphonates is permitted.


3.2.1 Sensory/motor neuropathy greater than or equal to Grade 2

3.2.2 QTc interval (Fridericia formula) > 450 msec for men or > 470 msec for women at study

entry; history of congenital long QT syndrome

3.2.3 Patients who are receiving any other investigational agents.

3.2.4 Patients with active brain metastases, CNS disease, or carcinomatous meningitis are excluded from this clinical trial. Patients with treated brain metastases, whose brain metastatic disease has remained stable for greater than or equal to 4 weeks without requiring steroid and anti-seizure medication, are eligible to participate.

3.2.5 History of allergic reactions attributed to compounds of similar chemical or biologic composition to study drugs. Patients who have previously received either clofarabine or bortezomib will be excluded as this may affect accurate determination of the MTD.

3.2.6 Uncontrolled intercurrent illness including, but not limited to, serious untreated infection, symptomatic respiratory failure/congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

3.2.7 Pregnant women are excluded from this study because bortezomib and clofarabine have been assigned to pregnancy category D by the FDA. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study drugs, breastfeeding should be discontinued prior to the first dose of study drug and women should refrain from nursing throughout the treatment period and for 3 months following the last dose of study drug.

3.2.8 HIV-positive patients on combination antiretroviral therapy are ineligible because of possible pharmacokinetic interactions with study drugs.

3.2.9 Both men and women of all races and ethnic groups are eligible for this trial.
