Brief Summary:
The goal of this clinical research study is to learn if the combination of the immunotherapy drugs, CT-011 and rituximab, can help control follicular lymphoma. The safety of this drug combination will also be studied.

Arm Intervention/treatment
Experimental: CT-011 in combination with Rituximab
Combination of the immunotherapy drugs, CT-011 and rituximab.
Drug: CT-011
Administered intravenously at a dose of 3.0 mg/kg on days 1, 29 (+/- 7 days), 57 (+/- 7 days), and 85 (+/- 7 days).
Other Name: Monoclonal Antibody CT-011
Drug: Rituximab
Administered intravenously at the standard dose of 375 mg/m^2 weekly for 4 weeks on days 17 (+/- 1 day), 24 (+/- 1 day), 31 (+/- 1 day), and 38 (+/- 1 day).
Other Name: Rituxan

Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: Response measured after completion of the second and fourth infusions of CT-011, and every 12 weeks thereafter for 2 years or until relapse. ]
    Overall response (OR) rate defined as complete response (CR) + partial response (PR). CR: Complete disappearance of all detectable clinical evidence of disease and symptoms if present before therapy. If a PET scan was positive before therapy, a post-treatment residual mass of any size was deemed a complete response provided that it was PET negative. If response was determined by CT scan criteria, lymph nodes that regressed to less than 1·5 cm were deemed to be complete response. The spleen and/or liver, if considered enlarged before therapy should not be palpable on physical examination and be considered normal size by imaging studies, and nodules related to lymphoma should disappear. PR: At least a 50% decrease in sum of the product of the diameters (SPD) of up to six of the largest dominant nodes or nodal masses. No increase in the size of other nodes, liver, or spleen. Splenic and hepatic nodules must regress by ≥ 50% in their SPD. No new sites of disease should be observed.

Secondary Outcome Measures :
  1. Progression-Free Survival [ Time Frame: Measured after completion of the second and fourth infusions of CT-011, and every 12 weeks thereafter for 2 years or until relapse. ]
    Progression-Free Survival (PFS) was measured from enrollment to disease progression or recurrence or death from any cause.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients with histologic proof of follicular lymphoma grade 1 or grade 2 relapsing after at least 1 but no more than 4 prior systemic therapies.Patients may have had prior local radiation therapy in addition to up to 4 prior systemic therapies. History of total body irradiation will be considered as prior systemic therapy.
  2. If patient received prior rituximab-based therapy, should have rituximab sensitive disease defined as a complete or partial response of at least 6 months duration with the rituximab-based regimen.
  3. Patients must be >= 18 years of age.
  4. Should have measurable (>= 1.5 cm) disease.
  5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  6. At least 4 weeks from last chemotherapy, immunotherapy, radiation therapy, monoclonal antibody therapy, or experimental therapy and must have recovered from acute toxic effects of prior therapy.
  7. Absolute neutrophil count >= 1.5 × 10^9/L.
  8. Platelets >= 50 × 10^9/L.
  9. Absolute lymphocyte count >= 0.6 × 10^9/L.
  10. Adequate renal function with creatinine <= 1.5 × the upper limit of normal (ULN).
  11. Adequate hepatic function with total bilirubin <= 1.5 mg/dL; AST and ALT <= 2.5 × ULN.
  12. Women of child-bearing potential (i.e., woman has not been naturally postmenopausal for at least 24 consecutive months or not surgically sterile) and sexually active men must agree to use 2 acceptable contraceptive methods during this study. One of the 2 methods of birth control must be a condom. Acceptable methods of birth control in combination with condoms include diaphragm, birth control pills, injections, intrauterine device, and/or under-the-skin implants. Men and women must agree to maintain effective contraception for up to 3 months after the last dose of drug is administered.
  13. Patients must sign an informed consent indicating that they are aware of the investigational nature of this study.

Exclusion Criteria:

  1. Patients positive for HIV, hepatitis B surface antigen, or hepatitis C antibody.
  2. Patients requiring concurrent immunosuppressive therapy are excluded. Inhaled or topical steroids for treating mild to moderate respiratory illnesses, allergies, skin rashes or ocular inflammations are allowed.
  3. History of central nervous system (CNS) lymphoma.
  4. Active or history of autoimmune disease except Hashimoto's thyroiditis. Patients with type I diabetes mellitus are excluded.
  5. Active infection or other serious intercurrent medical illness
  6. New York Heart Association Class III or IV disease.
  7. Pregnant or nursing.
  8. History of allogeneic stem cell transplantation.
  9. Other concurrent chemotherapy, radiotherapy, immunotherapy, or investigational therapy
  10. Any other malignancy except basal or squamous cell carcinoma of the skin, or cervical carcinoma in situ treated with curative intent. Any cancer from which the patient has been disease free for at least 5 years is permissible.
  11. Any underlying medical condition which, in the Principal Investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of adverse events.
