relapsed and/or refractory non-hodgkin lymphoma study

Conditions: Non-Hodgkin Lymphoma

Summary: the purpose of this study is to determine the rate of response to the drugs bortezomib (velcade) and vorinostat (zolinza), when used in combination, in patients with relapsed (recurrent) and/or refractory (difficult to treat) non-hodgkin lymphoma, and to determine the safety and tolerability of this regimen.

more selective and less toxic therapeutic strategies are needed to improve cure rates and prolong survival in patients with relapsed and/or refractory non-hodgkin lymphoma. amongst the multiple new pathways recently studied two have emerged as potentially important targets for new agents in lymphoma. these include the ubiquitin proteasome pathway and the biochemical reactions that control histone acetylation. the first two agents in each class to have been studied in lymphomas are: bortezomib and vorinostat. bortezomib has been granted fda approval for the treatment of mantle cell lymphoma and has established activity in a variety of b-cell lymphomas including follicular, marginal zone and diffuse large b-cell lymphoma. vorinostat or saha (suberoylanilide hydroxamic acid) has been fda approved for the treatment of refractory cutaneous t-cell lymphomas and has also shown activity in other lymphomas. synergistic activity between vorinostat and bortezomib has been observed in different cell lines. the proposed study will be a phase ii trial of the combination of vorinostat and bortezomib at the recommended dose-schedule in patients with recurrent and/or refractory lymphomas, indolent and aggressive, and b or t.

or oral, injectable, or implanted birth control; or abstinence ) to prevent pregnancy throughout the study, starting with visit 1 * female patients of childbearing potential must have a negative serum pregnancy test (beta-hcg) within 72 hours of enrollment and should not be nursing due to the potential for congenital abnormalities and of harm to nursing infants due to this treatment regimen * male patient agrees to use an adequate method of contraception (i.e., a condom if female partner uses a diaphragm, spermicidal jelly; or oral, injectable, or implanted birth control; or abstinence) for the duration of the study and for 12 weeks after the last dose * patient must be able to swallow capsules * signed and dated irb/ethics committee-approved informed consent before any protocol specific screening procedures are performed * both men and women of all races and ethnic groups are eligible for this trial exclusion criteria: * prior investigational therapy within 3 weeks of enrollment. investigational therapy is defined as treatment that is not approved for any indication * cns metastases, as indicated by clinical symptoms,cerebral edema, requirement for corticosteroids and/or progressive growth (treated cns metastases must be stable for greater than 2 weeks prior to enrollment) * active second malignancy that requires treatment or that would interfere with assessment of response * prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer with \< 5 years of documented disease-free status * treatment with the following within the timeframe specified prior to enrollment: * chemotherapy, radiotherapy, immunotherapy (active (such as vaccines) or passive (such as monoclonal antibodies or immunotoxins)) or major surgery \< or = to 3 weeks; * nitrosourea, or mitomycin \< or = to 6 weeks * radioimmunotherapy (e.g. bexxar or zevalin) \< or = to 12 weeks * concurrent enzyme-inducing anticonvulsant agents or valproic acid in last 4 weeks * prior bortezomib or any other proteasome inhibitor * prior vorinostat or any other histone deacetylase inhibitor * concurrent systemic corticosteroids (\<10 mg/day of prednisone or equivalent for adrenal insufficiency or acute allergic reactions allowed) * uncontrolled current illness including, but not limited to: * clinically or laboratory determined active infection * clinically limiting congestive heart failure or ejection fraction (ef) \<45% * clinically unstable angina pectoris (or myocardial infarction within 6 months of day 1) * clinically significant cardiac arrhythmia * limiting pulmonary hypertension * pre-existing neuropathy ≥ grade 2 * patients with pleural effusions, ascites or peripheral edema grade 2 or \> * hiv * active viral hepatitis * major surgery or significant traumatic injury within 21 days prior to enrollment (this does not apply to placement of a venous access device) * hypersensitivity to any of the components in vorinostat or bortezomib or agents containing boron or mannitol * significant psychiatric illness/social situations that would limit compliance with study medication and requirements of the study as determined by study md * significant medical illness or abnormal laboratory finding that would, in the investigator's judgment, increase the subject's risk by participating in this study
