Rituxan/Bendamustine/PCI-32765 in Relapsed DLBCL, MCL, or Indolent Non-Hodgkin's Lymphoma

Running, not enrolling · Phase 1

Conditions studied: Extranodal Marginal Zone B-cell Lymphoma of Mucosa-associated Lymphoid Tissue, Nodal Marginal Zone B-cell Lymphoma, Recurrent Adult Diffuse Large Cell Lymphoma, Recurrent Grade 1 Follicular Lymphoma, Recurrent Grade 2 Follicular Lymphoma, Recurrent Grade 3 Follicular Lymphoma, Recurrent Mantle Cell Lymphoma, Recurrent Marginal Zone Lymphoma, Splenic Marginal Zone Lymphoma, Waldenstrom Macroglobulinemia

In brief

This phase I trial studies the side effects and best dose of BTK inhibitor PCI-32765 when given together with rituximab and bendamustine hydrochloride in treating patients with recurrent non-Hodgkin lymphoma (NHL). BTK inhibitor PCI-32765 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving BTK inhibitor PCI-32765 together with rituximab and bendamustine hydrochloride may kill more cancer cells.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically confirmed B-cell NHL of the following subtypes: follicular, marginal zone (nodal, splenic, or extranodal), Waldenstrom's macroglobulinemia, diffuse large B-cell (DLCL) or mantle cell lymphoma (MCL) according to 2008 World Health Organization (WHO) criteria that is relapsed or refractory after at least 1 prior therapy
• Patients with DLCL must be relapsed or refractory after previous autologous stem cell transplant unless transplant is contraindicated
• Patients with MCL, follicular lymphoma (FL), marginal zone lymphoma, or Waldenstrom's macroglobulinemia are eligible after >= 1 prior therapies; however, patients with MCL who are not eligible for stem cell transplant (due to age or other co-morbidities) or refuse up-front stem cell transplantation may receive study treatment as their first-line therapy
• Body weight >= 40 kg
• Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
• Agreement to use contraception during the study and for 30 days after the last dose of study drug if sexually active and able to bear children
• Willing and able to participate in all required evaluations and procedures in this study protocol including swallowing capsules without difficulty
• Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (in accordance with national and local patient privacy regulations)

You may not qualify if…

• Prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer from which the patient has been disease free for at least 2 years or which will not limit survival to < 2 years (Note: these cases must be discussed with the Principal Investigator)
• A life-threatening illness, medical condition or organ system dysfunction which, in the investigator's opinion, could compromise the patient's safety, interfere with the absorption or metabolism of PCI-32765 PO, or put the study outcomes at undue risk
• Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening, or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification
• Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel or ulcerative colitis, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction
• Any immunotherapy, chemotherapy, radiotherapy, or experimental therapy within 3 weeks before first dose of study drug (corticosteroids for disease-related symptoms allowed but require 1-week washout before study drug administration)
• Use of medications known to prolong QTc interval or that may be associated with Torsades de Pointes are prohibited within 7 days of starting study drug and during treatment
• Central nervous system (CNS) involvement by lymphoma
• Grade >= 2 toxicity (other than alopecia) related to prior anticancer therapy including radiation
• Known history of human immunodeficiency virus (HIV), active infection with hepatitis C virus (HCV) or hepatitis B virus (HBV surface antigen positive), carriers of HBV (surface antigen and surface antibody negative, but HBV core antibody positive), or any uncontrolled active systemic infection
• Major surgery within 4 weeks before first dose of study drug
• Previous serious infusion reactions or hypersensitivity to rituximab or bendamustine not controlled or prevented by steroid pre-medication
• Creatinine > 2.0 mg/dL
