About
This phase II trial investigates how well brentuximab vedotin and bendamustine work in treating patients with follicular lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Brentuximab vedotin is a monoclonal antibody, brentuximab, linked to a toxic agent called vedotin. Brentuximab attaches to CD30 positive cancer cells in a targeted way and delivers vedotin to kill them. Chemotherapy drugs, such as bendamustine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial is being done to determine if the combination of brentuximab vedotin plus bendamustine is safe and to determine the effectiveness of the combination.
Full description
PRIMARY OBJECTIVE:
I. Obtain a preliminary estimate of the anti-tumor activity of brentuximab vedotin plus bendamustine hydrochloride (bendamustine) in patients with relapsed/refractory (R/R) CD30+ follicular lymphoma as determined by the complete response rate (CR) and best overall response rate (ORR) as defined per Lugano criteria.
SECONDARY OBJECTIVES:
To obtain the duration of response (DOR). To obtain the time to response (TTR). To obtain the progression-free survival (PFS) among subjects with relapsed or refractory CD30-positive follicular lymphoma (FL) receiving brentuximab vedotin and bendamustine. To obtain data on overall survival (OS). To evaluate the safety and tolerability.
OUTLINE:
Patients receive brentuximab vedotin intravenously (IV) over 30 minutes on day 1 and bendamustine IV over 60 minutes on days 1 and 2 of each cycle. Treatment repeats every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who respond to combination treatment and do not experience excessive toxicity may continue to receive additional single-agent brentuximab vedotin IV over 30 minutes on day 1 (once every 21 days) for up to 10 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days, and then every 3 months for 2 years.

Inclusion criteria
Histologically or cytologically confirmed relapsed or refractory follicular CD30+ non-Hodgkin lymphoma (NHL) (included in this category are follicular grade I, II, IIIa). CD30 positivity > 1% (tumor cells or surrounding peripheral microenvironment)
Patients must have measurable disease by computed tomography (CT) or positron emission tomography (PET) scan, with one or more sites of disease >= 1.5 cm in longest dimension
Relapsed or refractory disease after at least 1 prior regimen, defined using the 2014 Lugano classification
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
Life expectancy of greater than 3 months
Leukocytes >= 2,500/mcL
Absolute neutrophil count >= 1,000/mcL
Platelets >= 50,000/mcL
Hemoglobin >= 8 g/dL
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (however, patients with known Gilbert disease who have serum bilirubin level =< 3 x ULN may be enrolled)
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x ULN (AST and/or ALT =< 5 x ULN for patients with liver involvement)
Alkaline phosphatase =< 2.5 x ULN (=< 5 x ULN for patients with documented liver involvement or bone metastases)
Creatinine clearance >= 30 mL/min/1.73 m^2 by Cockcroft-Gault
Institutional normalized ratio (INR) and partial thromboplastin time (aPTT) =< 1.5 x ULN (This applies only to patients who do not receive therapeutic anticoagulation; patients receiving therapeutic anticoagulation, such as low-molecular-weight heparin or warfarin, should be on a stable dose.)
Administration of bendamustine or brentuximab vedotin may have an adverse effect on pregnancy and poses a risk to the human fetus, including embryo-lethality. 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, for the duration of study participation, and for 5 months (150 days) after the last dose of study agent. 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
Ability to understand and the willingness to sign a written informed consent document
Patients positive for human immunodeficiency virus (HIV) are allowed on study, but HIV-positive patients must have:
Exclusion criteria
Patients who have had chemotherapy, or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C, steroid treatment for follicular lymphoma is allowed per protocol) prior to entering the study or those who have not recovered from adverse events (other than alopecia) due to agents administered more than 2 weeks earlier. Specifically, the following therapies are not allowed:
Current or prior use of immunosuppressive medications (including, but not limited to, prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor [anti-TNF] agents) within 14 days prior to first dose (cycle 1, day 1). The following are exceptions to this criterion:
Patients with known uncontrolled central nervous system (CNS) involvement by lymphoma, including leptomeningeal involvement
History of hypersensitivity to bendamustine or brentuximab vedotin or any excipient
Known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies
History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
History of allergic reactions attributed to compounds of similar chemical or biologic composition to other agents used in study
Known clinically significant liver disease, including active viral, alcoholic, or other hepatitis; cirrhosis; fatty liver; and inherited liver disease.
Neuropathy grade > 1
Patients with eczema, psoriasis, lichen simplex chronicus of vitiligo with dermatologic manifestations only (e.g., patients with psoriatic arthritis would be excluded) are permitted provided that they meet the following conditions:
Patients with known active tuberculosis (TB) are excluded
Severe infections within 4 weeks prior to cycle 1, day 1, including, but not limited to, hospitalization for complications of infection, bacteremia, or severe pneumonia
Signs or symptoms of infection within 2 weeks prior to cycle 1, day 1
Received oral or intravenous (IV) antibiotics within 2 weeks prior to cycle 1, day 1. Patients receiving prophylactic antibiotics (e.g., for prevention of a urinary tract infection or chronic obstructive pulmonary disease) are eligible
Major surgical procedure within 28 days prior to cycle 1, day 1 or anticipation of need for a major surgical procedure during the course of the study
Influenza vaccination should be given during influenza season only (approximately October to March). Patients must not receive live, attenuated influenza vaccine within 4 weeks prior to cycle 1, day 1 or at any time during the study
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
