Brief summary
This research study is studying a combination of chemotherapy drugs as a possible treatment for aggressive lymphoma that has not responded to standard treatment. The names of the study interventions involved in this study are: * Cyclophosphamide * Alemtuzumab
Detailed description
This research study is a Phase I clinical trial, which tests the safety of an investigational intervention and also tries to define the appropriate dose of the investigational intervention to use for further studies. Investigational means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved alemtuzumab for aggressive lymphoma but it has been approved for other uses. In this research study, the investigators are studying the combination of cyclophosphamide and alemtuzumab in participants with several types of aggressive lymphoma which are positive for a protein called CD52, the target of alemtuzumab. Studies in laboratory models of CD52 positive lymphoma showed the combination of cyclophosphamide and alemtuzumab was very effective. Cyclophosphamide causes a specific type of immune cell, called a macrophage, to attack lymphoma cells treated with alemtuzumab. Both drugs have been used in participants with lymphoma but have not been previously combined in this way. The investigators hope to identify the highest dose of the drugs that can be safely given together and to see if the combination if effective in treating these lymphomas.
Interventions
DRUGCyclophosphamide
The chemotherapy drugs will be given in the hospital. During the first cycle of treatment, participants will stay in the hospital until their blood counts have recovered after treatment. During cycles 2 and 3, participants may go home after chemotherapy if they are doing well. The length of each cycle is 28 days \- Via IV Day 3
DRUGAlemtuzumab
* The chemotherapy drugs will be given in the hospital. During the first cycle of treatment, participants will stay in the hospital until their blood counts have recovered after treatment. During cycles 2 and 3, participants may go home after chemotherapy if they are doing well. The length of each cycle is 28 days * Alemtuzumab will be administered as follows: * IV Day 1 * IV Day 2 * Target dose IV on Day 3 and 4

Inclusion criteria
* Participants must have histologically confirmed non-Hodgkin lymphoma and be considered ineligible for standard curative therapeutic options, including high dose chemotherapy with autologous stem cell rescue. * Participants with the following subtypes of CD52 positive non-Hodgkin lymphoma (defined as ≥ 50% positive staining by immunohistochemical staining or flow cytometry by local lab) will be considered eligible: * High-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements (DHL) * DLBCL or high-grade B-cell lymphoma NOS or B-cell lymphoma unclassifiable with features intermediate between Burkitt lymphoma and diffuse large B-cell lymphoma with MYC and BCL2 protein over-expression by immunohistochemical (IHC) staining as defined by MYC expression in ≥ 40% of cells and BCL2 positivity ≥ 50% (DOL) * Transformed lymphoma with MYC rearrangement by FISH or over-expression by IHC, as above * CD52 positive mature T-cell lymphoproliferative disorder * There is no limit to the prior number of chemotherapy regimens. Patients with prior autologous or allogeneic stem cell transplantation, as well as prior therapy with cyclophosphamide or alemtuzumab, are eligible. * Age ≥ 18 and ≤75 * ECOG performance status ≤2 (Karnofsky ≥60%, see Appendix A) * Participants must have normal organ and marrow function as defined by peripheral blood values below: * leukocytes ≥1,000/mcL * absolute neutrophil count ≥500/mcL * platelets ≥25,000/mcL * total bilirubin ≤ 2 × institutional upper limit of normal (ULN) unless related to Gilbert's disease * AST(SGOT)/ALT(SGPT) ≤ 3 × institutional ULN * creatinine clearance \< 1.5 x institutional ULN * Ability to understand and the willingness to sign a written informed consent document.
Exclusion criteria
* Participants who have had chemotherapy or radiotherapy within 1 weeks (4 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. * Participants who are receiving any other investigational agents for their lymphoma. * Participants receiving corticosteroids within the past 1 week. * Participants with known active CNS involvement by lymphoma should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. * History of allergic reactions attributed to cyclophosphamide or alemtuzumab * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, uncontrolled hematuria related to bladder injury or psychiatric illness/social situations that could limit compliance with study requirements. * Pregnant women are excluded from this study because cyclophosphamide and alemtuzumab at these doses have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these agents, breastfeeding should be discontinued. Negative serum pregnancy test will be required for women of childbearing potential. * HIV-positive participants on combination antiretroviral therapy are ineligible because of the increased risk of lethal infections when treated with marrow-suppressive therapy.
