Chemotherapy Followed by Zevalin for Relapsed Mantle Cell Lymphoma

Condition(s) targeted: Mantle Cell Lymphoma

Intervention: Fludarabine (Drug); Mitoxantrone (Drug); Rituximab (Drug); Zevalin (Drug)

Phase: Phase 2

Status: Active, not recruiting

Sponsored by: Dana-Farber Cancer Institute

- The purpose of this study is to find out whether combining a short course of

chemotherapy (Fludarabine, Mitoxantrone and Rituximab) followed by Zevalin will be effective in treating relapsed mantle cell lymphoma.

- The secondary purposes of the study are to determine the safety and to evaluate whether

there is additional benefit from Zevalin therapy following the chemotherapy.

Official title: Abbreviated Fludarabine / Mitoxantrone / Rituximab Chemotherapy Followed by Zevalin for Relapsed Mantle Cell Lymphoma

Study design: Treatment, Non-Randomized, Open Label, Single Group Assignment, Safety/Efficacy Study

Primary outcome: The primary objective is to determine the response rate to two cycles of FMR + Zevalin in patients with relapsed mantle cell lymphoma, using a two-stage design.

Secondary outcome:

To describe the progression-free survival

To determine the safety of FMR + Zevalin in these subjects

To determine the impact of Zevalin on minimal residual disease in subjects with relapsed mantle cell lymphoma

Detailed description:

- Patients receive fludarabine (days 1-3), mitoxantrone (day 1), and rituximab (day 1) of

each 28-day cycle.

- Patients undergo a CT scan and bone marrow biopsy after two cycles. Unless the cancer

has progressed, the patient will then receive Zevalin study treatment.

- Blood counts are taken every week for 12 weeks. After 12 weeks, a CT scan and bone

marrow biopsy are performed.

- Long-term followup is 4 years. Physical exam and blood work is performed every 3 months

for the first two years. Following that, physical exams and blood work is every 6 months for another two years. CT scans and bone marrow biopsies are every 6 months during this 4 year followup period.

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Histologically confirmed mantle cell lymphoma in 1st or 2nd relapse, or with

persistent disease following induction therapy.

- Measurable disease (lymph node > 1. 5 cm)

- No anti-cancer therapy for three weeks (six weeks if Rituximab, nitrosourea or

Mitomycin C) prior to study initiation, and fully recovered from all toxicities associated with prior surgery, radiation treatments, chemotherapy, or immunotherapy

- An IRB-approved signed informed consent

- Age >/= 18 years

- Expected survival >/= 3 months

- ECOG performance status 0, 1, or 2

- Acceptable hematologic status within two weeks prior to registration, including: *

Absolute neutrophil count ([segmented neutrophils + bands] x total WBC) ≥ 1,500/mm3; * Platelet counts ≥ 100,000/mm3

- Female patients who are not pregnant or lactating

- Men and women of reproductive potential who are following accepted birth control

methods (as determined by the treating physician, however abstinence is not an acceptable method)

- Patients previously on Phase II drugs if no long-term toxicity is expected, and the

patient has been off the drug for eight or more weeks with no significant post treatment toxicities observed

Inclusion Criteria for Proceeding with Zevalin:

- Hematologic recovery from FMR (ANC >1500, platelets > 100,000)

- Stable or responding disease on restaging following two cycles of FMR

- < 25% of bone marrow cellularity involved with lymphoma on restaging bone marrow

biopsy

- Bone marrow cellularity at least 20% (including lymphoma and normal cells)

- Total bilirubin < 2. 0 mg/dL (if total bilirubin is >75% indirect, then may use direct

bilirubin < 0. 8 mg/dL)

- Serum creatinine < 2. 0 mg/dL

- No G-CSF or GM-CSF therapy within two weeks prior to Zevalin treatment, or neulasta

within four weeks prior to Zevalin treatment

- No evidence of altered biodistribution of 111-In-Zevalin as indicated by:

1. Absent cardiac blood pool on day 1, with high liver / spleen uptake

2. Lung uptake greater than blood pool on day 1 or greater than liver on day 2-3

3. Kidney (in posterior view) or bowel uptake greater than liver on day 2-3

Exclusion Criteria:

- Patients with impaired bone marrow reserve, as indicated by one or more of the

following: * Prior myeloablative therapies with allogeneic or autologous bone marrow transplantation (ABMT) or peripheral blood stem cell (PBSC) rescue; * Platelet count < 100,000 cells/mm3; * Prior external beam radiation to >25% of active bone marrow; * History of failed stem cell collection

- Prior radioimmunotherapy

- Known cardiac ejection fraction < 40%. In patients with prior adriamycin exposure >=

300 mg/m2, echocardiogram must be obtained within three months prior to registration

- Known CNS lymphoma (lumbar puncture only required if symptomatic)

- Chronic lymphocytic leukemia (CLL)

- HIV or AIDS-related lymphoma

- Pleural effusion or ascites

- Abnormal liver function: total bilirubin > 2. 0 mg/dL (if total bilirubin is >75%

indirect, then may use direct bilirubin > 0. 8 mg/dL)

- Abnormal renal function: serum creatinine > 2. 0 mg/dL

- G-CSF or GM-CSF therapy within two weeks prior to treatment, or neulasta within four

weeks

- Positive direct antiglobulin test

- Major surgery, other than diagnostic surgery, within four weeks

- Serious nonmalignant disease or infection which in the opinion of the investigator

would compromise protocol objectives
